Description

オゾン液生成器及びオゾン液生成方法ならびに便器Ozone liquid generator, ozone liquid generation method and toilet
　本発明は、オゾン液生成器及びオゾン液生成方法ならびに便器に関し、特に、オゾンガス循環式のオゾン液生成器及びオゾン液生成方法ならびに当該オゾン液生成器を備えた便器に関する。 The present invention relates to an ozone liquid generator, an ozone liquid generation method, and a toilet, and more particularly to an ozone gas circulation type ozone liquid generator, an ozone liquid generation method, and a toilet equipped with the ozone liquid generator.
　通常、オゾン液生成器には、オゾンガスを発生させるオゾンガス発生器が搭載される。一般的なオゾンガス発生器においては、絶縁物を挟んだ電極間に交流電圧が印加されることで無声放電が発生させられ、これら電極間に大気圧以上の空気または酸素などの気体が通過させられることにより、オゾンガスが発生する。オゾン液生成器においては、発生させたオゾンガスと水などの液体とが気液混合器において混合させることにより、オゾン液が生成される。 Ordinarily, an ozone gas generator that generates ozone gas is mounted on the ozone liquid generator. In a general ozone gas generator, a silent discharge is generated by applying an alternating voltage between electrodes sandwiching an insulator, and a gas such as air or oxygen at atmospheric pressure or higher is passed between these electrodes. As a result, ozone gas is generated. In the ozone liquid generator, the ozone liquid is generated by mixing the generated ozone gas and a liquid such as water in a gas-liquid mixer.
　オゾン液生成器は、浄水、洗浄、消臭などの目的に使用されるため、浄水器、トイレ、医療現場などの製品に搭載される場合が多い。そのため、殺菌力や消臭力が強い高濃度のオゾン水を生成することができるオゾン液生成器の開発がなされている。 Ozone liquid generators are often used for products such as water purifiers, toilets, and medical sites because they are used for purposes such as water purification, washing, and deodorization. Therefore, an ozone liquid generator capable of generating high-concentration ozone water having strong sterilizing power and deodorizing power has been developed.
　例えば、特開平２０１０－６４０５９号公報（特許文献１）には、オゾンガス混合機構とガス分離タンクとオゾンガス接触機構とを備えたオゾン水製造装置が開示されている。当該オゾン水製造装置にあっては、オゾンガス混合機構とガス分離タンクとに接続されたオゾン水循環ラインにオゾン水を循環させてその高濃度化が図られていると共に、生成したオゾンガスを有効に利用するため、ガス分離タンクで分離された廃オゾンガスをオゾンガス接触機構に供給し、廃オゾンガスと純水とを混合させて生成したオゾン水をオゾン水循環ラインに供給している。 For example, Japanese Patent Laid-Open No. 2010-64059 (Patent Document 1) discloses an ozone water production apparatus including an ozone gas mixing mechanism, a gas separation tank, and an ozone gas contact mechanism. In the ozone water production system, ozone water is circulated through the ozone water circulation line connected to the ozone gas mixing mechanism and the gas separation tank to increase its concentration, and the generated ozone gas is used effectively. Therefore, waste ozone gas separated in the gas separation tank is supplied to an ozone gas contact mechanism, and ozone water generated by mixing waste ozone gas and pure water is supplied to an ozone water circulation line.
　ここで、上記オゾンガス接触機構は、フッ素樹脂で形成された膜を有し、膜によって区画された一方の室に純水を、他方の室にオゾンガスをそれぞれ供給してオゾン水を生成している。生成されたオゾン水は、その後、オゾン水循環ラインに供給されることになり、これによりオゾンガスの有効利用を図り、安定したオゾン濃度のオゾン水の提供を可能にしている。 Here, the ozone gas contact mechanism has a film made of a fluororesin, and supplies pure water to one chamber partitioned by the film and ozone gas to the other chamber to generate ozone water. . The generated ozone water is then supplied to the ozone water circulation line, thereby making it possible to effectively use ozone gas and to provide ozone water having a stable ozone concentration.
特開平２０１０－６４０５９号公報JP 2010-64059 A
　しかしながら、上記公報に開示のオゾン水製造装置にあっては、オゾンガス発生器が設けられておらず、オゾン水を生成するためにオゾンガス混合機構が設けられ、オゾン水製造装置の外部からオゾンガス混合機構にオゾンガスを導入することで、オゾン水を生成させている。また、廃オゾンガスからオゾン水を生成するために、上記オゾン水製造装置にあっては、オゾンガス混合機構を設けることでオゾン水を生成することとしている。このため、２種類のオゾンガス混合手段及び複雑な配管経路を設けることが必要となり、装置の大型化を招くという問題が生じてしまう。 However, in the ozone water production apparatus disclosed in the above publication, an ozone gas generator is not provided, an ozone gas mixing mechanism is provided to generate ozone water, and an ozone gas mixing mechanism is provided from the outside of the ozone water production apparatus. Ozone water is generated by introducing ozone gas into the tank. Moreover, in order to produce | generate ozone water from waste ozone gas, in the said ozone water manufacturing apparatus, it is supposed that ozone water is produced | generated by providing an ozone gas mixing mechanism. For this reason, it is necessary to provide two types of ozone gas mixing means and a complicated piping path, which causes a problem of increasing the size of the apparatus.
　加えて、上記オゾン水製造装置においては、廃オゾンガスの再利用が可能なオゾンガス混合機構にて比較的低濃度のオゾン水を生成する場合には、オゾン水循環ラインを循環するオゾン水の高濃度化を図ることが可能ではあるが、オゾンガス混合機構にて高濃度のオゾン水を生成する場合には、オゾン水の高濃度化を図ることができない問題が生じてしまう。これは、廃オゾンガスのオゾン濃度が、外部から供給されるオゾンガスのオゾン濃度に比べて低いためであり、オゾンガス接触機構にて混合されるオゾン水のオゾン濃度が、オゾンガス混合機構にて混合されるオゾン水のオゾン濃度に比べて低くなることに起因している。すなわち、オゾン水循環ラインを比較的高濃度のオゾン水が循環している場合には、オゾンガス接触機構により生成された低濃度のオゾン水を導入することで、逆に循環するオゾン水の低濃度化を招くこととなってしまう。 In addition, in the above-mentioned ozone water production apparatus, when generating ozone water having a relatively low concentration with an ozone gas mixing mechanism capable of reusing waste ozone gas, the concentration of ozone water circulating in the ozone water circulation line is increased. However, when high-concentration ozone water is generated by the ozone gas mixing mechanism, there is a problem that the concentration of ozone water cannot be increased. This is because the ozone concentration of waste ozone gas is lower than the ozone concentration of ozone gas supplied from the outside, and the ozone concentration of ozone water mixed by the ozone gas contact mechanism is mixed by the ozone gas mixing mechanism. This is due to the fact that it becomes lower than the ozone concentration of ozone water. In other words, when ozone water with a relatively high concentration is circulating in the ozone water circulation line, the concentration of ozone water that is circulated is reduced by introducing ozone water with a low concentration generated by the ozone gas contact mechanism. Will be invited.

It is possible to provide an ozone liquid generator, an ozone liquid generation method, and a toilet equipped with the ozone liquid generator.

　オゾン液生成器１００の気体循環経路Ａは、オゾンガス発生器１０１と気液混合器１０２と気液分離器１０３とに接続され、オゾンガスを含有する気体を循環させることで、高濃度のオゾンガスを生成する。一方、液体循環経路Ｂ１は、気液混合器１０２と気液分離器１０３と貯液槽１１５とに接続され、オゾン液などの液体を循環し、生成させたオゾンガスと気液混合器１０２において混合させることで、高濃度のオゾン液を生成する。生成された高濃度のオゾン液は、貯液槽１１５、気液分離器１０３または液体循環経路Ｂ１に貯液され、洗浄、殺菌、消臭などの用途に利用するためにオゾン液生成器１００外に導出される。なお、オゾン液生成器１００は、様々な製品、例えば、浄水器、トイレ用、医療用などの製品に組み込まれて利用することが可能である。 The gas circulation path A of the ozone liquid generator 100 is connected to the ozone gas generator 101, the gas-liquid mixer 102, and the gas-liquid separator 103, and circulates a gas containing ozone gas to generate high-concentration ozone gas. To do. On the other hand, the liquid circulation path B1 is connected to the gas-liquid mixer 102, the gas-liquid separator 103, and the liquid storage tank 115, circulates a liquid such as ozone liquid, and mixes in the generated ozone gas and the gas-liquid mixer 102. By doing so, high-concentration ozone liquid is generated. The generated high-concentration ozone liquid is stored in the liquid storage tank 115, the gas-liquid separator 103 or the liquid circulation path B1, and is used outside the ozone liquid generator 100 for use in applications such as cleaning, sterilization, and deodorization. To be derived. The ozone liquid generator 100 can be used by being incorporated into various products such as water purifiers, toilets, and medical products.
　オゾンガス発生器１０１は、空気または酸素などの気体を導入する配管ａと接続された導入口１０４と、金属などの電極により形成され、導入された空気や酸素を材料にオゾンガスを発生させるオゾンガス発生素子と、オゾンガスを導出する導出口１０５とを備えている。オゾンガス発生器１０１は、導入口１０４より導入された酸素または空気に含まれる酸素からオゾンガスを生成し、導出口１０５からオゾンガスを導出する。また、オゾンガス発生器１０１は、より高密度の酸素や空気などの気体をもとにオゾンガスを生成した場合には、より高濃度のオゾンガスを生成する。これは、オゾンガス発生素子に接触する酸素濃度が上昇し、オゾンガスの発生量が増加することに起因する。ここで、オゾンガス発生器１０１は、導入される空気や酸素などの気体からオゾンガスを生成する構成であれば、一般的なオゾンガス発生器を用いることが可能である。 The ozone gas generator 101 is formed by an inlet 104 connected to a pipe a for introducing a gas such as air or oxygen, and an electrode such as a metal, and an ozone gas generating element that generates ozone gas using the introduced air or oxygen as a material. And an outlet 105 for deriving ozone gas. The ozone gas generator 101 generates ozone gas from oxygen introduced from the introduction port 104 or oxygen contained in the air, and derives ozone gas from the discharge port 105. Further, the ozone gas generator 101 generates ozone gas having a higher concentration when the ozone gas is generated based on a gas having higher density such as oxygen or air. This is because the oxygen concentration in contact with the ozone gas generating element increases and the amount of ozone gas generated increases. Here, if the ozone gas generator 101 is a structure which produces | generates ozone gas from gas, such as air and oxygen introduce | transduced, it is possible to use a general ozone gas generator.
　気液混合器１０２は、水などの液体を導入する導入口１０６と、配管ｂに接続されオゾンガスや空気などの気体を導入する導入口１０７と、配管ｃに接続され、気体と液体とを混合した気液混合体を導出する導出口１０８とを備えている。導入口１０６から導入された水などの液体は、導入口１０７から導入された空気やオゾンガスなどの気体と混合され、導出口１０８からオゾン液などの気液混合体として導出される。 The gas-liquid mixer 102 is connected to the inlet 106 that introduces a liquid such as water, the inlet 107 that is connected to the pipe b and introduces a gas such as ozone gas or air, and is connected to the pipe c to mix the gas and the liquid. And an outlet 108 for extracting the gas-liquid mixture. A liquid such as water introduced from the introduction port 106 is mixed with a gas such as air or ozone gas introduced from the introduction port 107, and is led out from the outlet 108 as a gas-liquid mixture such as ozone liquid.
　ここで、気液混合体は、液体に気体が溶解した液体、または、液体に気体が気泡として含有された気体含有液が混合された状態のものを意味し、「液体」の概念に含まれる用語として使用する。また、オゾン液は、液体にオゾンガスが溶け込んだオゾン溶液、または、液体にオゾンガスが気泡として混合されるオゾン含有液が含まれる用語として使用する。また、混合される液体には、水や農耕用の溶媒として利用される栽培養液や医療用の溶媒として利用される溶液など、オゾンガスを混合させる溶液が含まれる。 Here, the gas-liquid mixture means a liquid in which a gas is dissolved in a liquid, or a gas-containing liquid in which a gas is contained in a liquid as bubbles, and is included in the concept of “liquid”. Use as a term. The ozone liquid is used as a term that includes an ozone solution in which ozone gas is dissolved in a liquid, or an ozone-containing liquid in which ozone gas is mixed as bubbles in the liquid. The liquid to be mixed includes a solution in which ozone gas is mixed, such as water or a cultivation nutrient solution used as an agricultural solvent or a solution used as a medical solvent.
　なお、気液混合器１０２は、より高密度の気体が導入されてこれが液体と混合される場合において、より高い気液混合率にて混合される。これは、例えば気液混合器にて水とオゾンガスとが混合される場合に、水と接触するオゾンガスのオゾン濃度が上昇するため、より効率的に溶解できることに起因する。 Note that the gas-liquid mixer 102 is mixed at a higher gas-liquid mixing rate when a higher-density gas is introduced and mixed with the liquid. This is because, for example, when water and ozone gas are mixed in a gas-liquid mixer, the ozone concentration of ozone gas in contact with water increases, so that it can be dissolved more efficiently.
　次に、気液混合器１０２の一構成例の詳細について、図２を用いて説明する。図２は、ベンチュリー型の気液混合器の概略説明図である。 Next, details of one configuration example of the gas-liquid mixer 102 will be described with reference to FIG. FIG. 2 is a schematic explanatory diagram of a Venturi type gas-liquid mixer.
　ベンチュリー型の気液混合器１０２（ａ）は、液体が導入される導入口１０６と、導入口１０６と連通した導入経路２１と、導入経路２１に連通し、導入経路２１に比べて小さな径を有する連通経路２２と、連通経路２２と連通し、連通経路２２に比べて大きな径を有する導出経路２３と、導出経路２３に連通された導出口１０８とを備え、導出口１０８からは液体が導出される。 The venturi-type gas-liquid mixer 102 (a) has an introduction port 106 through which a liquid is introduced, an introduction path 21 communicating with the introduction port 106, a communication with the introduction path 21, and a smaller diameter than the introduction path 21. A communication path 22, a lead-out path 23 that communicates with the communication path 22 and has a larger diameter than the communication path 22, and a lead-out port 108 that communicates with the lead-out path 23. Liquid is led out from the lead-out port 108. Is done.
　また、連通経路２２は、経路の途中に開設して設けられた導入口１０７を備え、配管ｂを介してオゾンガス発生器１０１と接続されている。ここで、開設とは、配管の側面に穴などを設けることを意味し、穴として配管に開設された開設口は、他の配管と連通させて接続させることが可能である。なお、穴の形状は、丸、楕円、多角形など適宜、自由に設計して構わない。 Further, the communication path 22 includes an introduction port 107 that is opened and provided in the middle of the path, and is connected to the ozone gas generator 101 via the pipe b. Here, the term “opening” means that a hole or the like is provided on the side surface of the pipe, and the opening opening opened in the pipe as a hole can be connected to and connected to other pipes. The shape of the hole may be freely designed such as a circle, an ellipse, or a polygon.
　導入口１０６から液体を導入することで導入経路２１を通り、連通経路２２に到達した液体は、導入経路２１に比べ細い管に導入されることになるため、ベルヌーイの定理に知られるように、流速が増加し静圧が減少する。この結果、流動する液体の静圧は負圧になり、配管ｂを介して連通経路２２に向かって気体が自吸される。その後、導入された気体と液体とが混合され、導出経路２３と連通された導出口１０８から気液混合体として導出される。例えば、オゾンガス発生器１０１により発生させたオゾンガスを導入口１０７から導入し、水を導入口１０６から導入させる場合には、水とオゾンガスとが混合されてオゾン水が生成される。ここで、気液混合器の一構成例として、図２のベンチュリー型の気液混合器１０２（ａ）を用いた場合について説明したが、他の構成の気液混合器を用いても構わない。 By introducing the liquid from the inlet 106, the liquid that has reached the communication path 22 through the introduction path 21 is introduced into a narrower tube than the introduction path 21, so that Bernoulli's theorem is known, The flow rate increases and the static pressure decreases. As a result, the static pressure of the flowing liquid becomes negative, and the gas is self-primed toward the communication path 22 through the pipe b. Thereafter, the introduced gas and liquid are mixed and led out as a gas-liquid mixture from the outlet 108 connected to the outlet path 23. For example, when ozone gas generated by the ozone gas generator 101 is introduced from the inlet 107 and water is introduced from the inlet 106, water and ozone gas are mixed to generate ozone water. Here, as a configuration example of the gas-liquid mixer, the case where the venturi-type gas-liquid mixer 102 (a) in FIG. 2 is used has been described, but a gas-liquid mixer having another configuration may be used. .
　図１の気液分離器１０３は、導入された気体を含有する気体含有液を気体と液体とに分離して導出することが可能であり、例えば第１構成例に係る気液分離器１０３においては、これが密封可能な容器などから形成される。気液分離器１０３は、配管ｃに接続され、液体を導入する導入口１０９と、オゾン液生成器１００の外部へ水やオゾン液などの液体を導出する液体導出口１１０と、配管ａに接続され、空気やオゾンガスなどの気体を循環させるための気体循環口１１１と、配管ｅに接続され、水やオゾン液などの液体を循環させるための液体循環口１１２とを備えている。 The gas-liquid separator 103 in FIG. 1 can separate and derive the gas-containing liquid containing the introduced gas into a gas and a liquid. In the gas-liquid separator 103 according to the first configuration example, for example, Is formed from a container which can be sealed. The gas-liquid separator 103 is connected to the pipe c and connected to the inlet 109 for introducing the liquid, the liquid outlet 110 for leading the liquid such as water and ozone liquid to the outside of the ozone liquid generator 100, and the pipe a. And a gas circulation port 111 for circulating a gas such as air or ozone gas, and a liquid circulation port 112 connected to the pipe e for circulating a liquid such as water or ozone liquid.
　気液分離器１０３においては、気体を含有した液体が導入口１０９から導入されると、気液分離器１０３の下層において比重の重い液体が貯液され、上層において液体に含有されていた比重の軽い空気やオゾンガスなどの気体が貯蔵されることなる。このため、気液分離器１０３によって、気体が含有された液体を気体と液体とに分離することが可能となる。例えば、オゾンガスが含有されるオゾン液が気液分離器１０３の導入口１０９から導入される場合には、オゾン液に気泡として含まれていたオゾンガスや空気などの気体が分離され、これが気液分離器１０３の上層に貯蔵され、気液分離器１０３の下層にオゾンガスが溶解したオゾン溶液が貯液される。 In the gas-liquid separator 103, when a liquid containing gas is introduced from the inlet 109, a liquid having a high specific gravity is stored in the lower layer of the gas-liquid separator 103, and the specific gravity contained in the liquid in the upper layer is stored. Gases such as light air and ozone gas are stored. For this reason, the gas-liquid separator 103 can separate the liquid containing the gas into the gas and the liquid. For example, when ozone liquid containing ozone gas is introduced from the inlet 109 of the gas-liquid separator 103, gases such as ozone gas and air contained in the ozone liquid as bubbles are separated, and this is gas-liquid separation. The ozone solution in which ozone gas is dissolved is stored in the lower layer of the gas-liquid separator 103 and stored in the upper layer of the vessel 103.
　また、気体循環口１１１は、液体導出口１１０や液体循環口１１２と比較した場合に、重力方向に沿って高い位置に設けられている。このため、気液分離器１０３に貯蔵された空気やオゾンガスなどは、気液分離器１０３の気体循環口１１１から配管ａに効率的に導出される。 Further, the gas circulation port 111 is provided at a higher position along the direction of gravity when compared with the liquid outlet port 110 and the liquid circulation port 112. For this reason, air, ozone gas, etc. stored in the gas-liquid separator 103 are efficiently led out from the gas circulation port 111 of the gas-liquid separator 103 to the pipe a.
　一方、液体導出口１１０は、貯液された液体の水位が液体導出口１１０が設けられた高さを超えたときにオゾン液生成器１００の外部にこれを導出することが可能である。なお、液体導出口１１０またはこれに接続された配管には、第１の開閉弁Ｖ１が設けられ、これにより液体の導出量を制御することができる。 On the other hand, the liquid outlet 110 can lead out the ozone liquid generator 100 when the water level of the stored liquid exceeds the height at which the liquid outlet 110 is provided. The liquid outlet 110 or a pipe connected thereto is provided with a first on-off valve V1, whereby the amount of liquid discharged can be controlled.
　また、液体循環口１１２は、気液混合器１０２に液体を循環させるための配管ｅに接続され、気液分離器１０３に貯液された液体を気液混合器１０２に循環させることが可能である。 The liquid circulation port 112 is connected to a pipe e for circulating the liquid to the gas-liquid mixer 102, and the liquid stored in the gas-liquid separator 103 can be circulated to the gas-liquid mixer 102. is there.
　なお、図面においては、液体導出口１１０及び液体循環口１１２の２つの導出口を設けているが、液体導出口１１０と液体循環口１１２とを共有させて１つの導出口を設け、導出口に二股に分岐させた配管を接続させた構成にしても構わない。 In the drawing, the two outlets of the liquid outlet 110 and the liquid circulation port 112 are provided. However, the liquid outlet 110 and the liquid circulation port 112 are shared, and one outlet is provided. You may make it the structure which connected the piping branched into two branches.
　また、気液分離器１０３の貯液許容量は、オゾン液生成器１００の用途に応じて適宜変更が可能である。なお、気液分離器１０３は、気体含有液を気体と液体とに分離して導出できる構成であれば、他の構成を有した一般的な気液分離器を備えていても構わない。 Further, the liquid storage allowable amount of the gas-liquid separator 103 can be appropriately changed according to the use of the ozone liquid generator 100. Note that the gas-liquid separator 103 may include a general gas-liquid separator having another configuration as long as the gas-containing liquid can be separated into gas and liquid and derived.
　また、気液分離器１０３には、気体と液体とへの気液分離の効率を向上させるために、気液分離器１０３に導入された液体の流動を抑制する位置に流動抑制板などの流動抑制手段を設けてもよい。例えば、液体導出口１１０を閉状態にし、液体循環口１１２を開状態にして、導入口１０９から液体を導入させる場合に、気液分離器１０３に導入される気泡が含まれた液体が、導入口１０９から液体循環口１１２へと高速に流動してしまい、液体に含まれる気泡を気液分離しきれずに、これが液体循環口１１２から導出されてしまうことがある。このため、気液分離器１０３内で液体の流動速度を抑え、気液分離の効率を向上させることが効果的である。 In addition, the gas-liquid separator 103 has a flow suppression plate or the like at a position where the flow of the liquid introduced into the gas-liquid separator 103 is suppressed in order to improve the efficiency of gas-liquid separation into gas and liquid. Suppression means may be provided. For example, when the liquid outlet 110 is closed, the liquid circulation port 112 is opened, and liquid is introduced from the inlet 109, the liquid containing bubbles introduced into the gas-liquid separator 103 is introduced. The liquid may flow from the port 109 to the liquid circulation port 112 at a high speed, and the bubbles contained in the liquid may not be completely separated from the gas and the liquid may be led out from the liquid circulation port 112. For this reason, it is effective to suppress the flow rate of the liquid in the gas-liquid separator 103 and improve the efficiency of gas-liquid separation.
　例えば、図３Ａ及び図３Ｂのように、容器内に流動抑制板を備えた気液分離器１０３（ａ）を用い、気液分離の効率を向上させてもよい。図３Ａ及び図３Ｂは、本実施形態に係るオゾン液生成器に具備される気液分離器の第２構成例を示す斜視図及び断面図であり、当該気液分離器１０３（ａ）は、図１の第１構成例に係る気液分離器１０３の底面に流動抑制手段を設けた構成を有している。 For example, as shown in FIGS. 3A and 3B, a gas-liquid separator 103 (a) provided with a flow suppression plate in the container may be used to improve the efficiency of gas-liquid separation. 3A and 3B are a perspective view and a cross-sectional view showing a second configuration example of the gas-liquid separator provided in the ozone liquid generator according to the present embodiment, and the gas-liquid separator 103 (a) It has the structure which provided the flow suppression means in the bottom face of the gas-liquid separator 103 which concerns on the 1st structural example of FIG.
　図３Ａ及び図３Ｂの気液分離器１０３（ａ）は、外壁３１に囲まれた密封可能な容器部１２０を有し、容器部１２０に液体を導入する導入口１０９と、オゾン液などの液体を導出する液体導出口１１０と、気体を導出する気体循環口１１１と、液体を導出する液体循環口１１２と、流動抑制板３２とを備えている。なお、気液分離器１０３（ａ）には、液体導出口１１０及び液体循環口１１２の２つの導出口を設けているが、１つの導出口により共有させた構成としてもよい。また、液体導出口１１０を利用しないオゾン液生成器の構成では、液体導出口１１０を設ける必要はない。 The gas-liquid separator 103 (a) in FIGS. 3A and 3B has a sealable container part 120 surrounded by an outer wall 31, an inlet 109 for introducing a liquid into the container part 120, and a liquid such as ozone liquid. The liquid outlet 110 for extracting the gas, the gas circulation port 111 for extracting the gas, the liquid circulation port 112 for extracting the liquid, and the flow suppression plate 32 are provided. The gas-liquid separator 103 (a) is provided with two outlets, ie, the liquid outlet 110 and the liquid circulation port 112, but may be configured to be shared by one outlet. Further, in the configuration of the ozone liquid generator that does not use the liquid outlet 110, it is not necessary to provide the liquid outlet 110.
　気体循環口１１１は、気液分離器１０３（ａ）に設けられた液体循環口１１２の位置よりも重力方向に沿って高い位置に設けられ、効率的に気体を導出させるために、容器部１２０の天井近傍に設けられることがよい。また、液体導出口１１０及び液体循環口１１２は、効率的に液体を導出させるために、容器部１２０の底面近傍に設けることがよい。 The gas circulation port 111 is provided at a position higher in the direction of gravity than the position of the liquid circulation port 112 provided in the gas-liquid separator 103 (a), and in order to efficiently lead out the gas, the container portion 120 is provided. It is preferable to be provided in the vicinity of the ceiling. Further, the liquid outlet 110 and the liquid circulation port 112 are preferably provided in the vicinity of the bottom surface of the container portion 120 in order to efficiently lead out the liquid.
　流動抑制板３２は、容器部１２０の底面に配置され、導入口１０９から導入された液体の流動を抑制する流動抑制手段としての役割を担う。なお、図３Ａ及び図３Ｂでは、長方体状の流動抑制板３２を記載しているが、導入される液体の流動を抑制することができれば、多角柱状や多角錐状、円弧状の壁など、他の形状の流動抑制板を形成しても構わない。 The flow suppression plate 32 is disposed on the bottom surface of the container 120 and plays a role as a flow suppression means for suppressing the flow of the liquid introduced from the inlet 109. In FIGS. 3A and 3B, a rectangular flow suppression plate 32 is shown. However, if the flow of the introduced liquid can be suppressed, a polygonal column shape, a polygonal pyramid shape, an arc-shaped wall, etc. Other shapes of flow suppression plates may be formed.
　導入口１０９から導入された液体は、流動抑制板３２に衝突し、液体の流動速度が抑制された後に、液体導出口１１０または液体循環口１１２から導出される。このため、導入された液体は、一定時間にわたって気液分離器１０３（ａ）内を滞留することになるため、オゾン液に含まれるオゾンガスなどの気体の分離をより効果的に行うことが可能となる。 The liquid introduced from the introduction port 109 collides with the flow suppressing plate 32 and is discharged from the liquid outlet port 110 or the liquid circulation port 112 after the flow rate of the liquid is suppressed. For this reason, since the introduced liquid stays in the gas-liquid separator 103 (a) for a certain period of time, it is possible to more effectively separate gases such as ozone gas contained in the ozone liquid. Become.
　また、例えば図４Ａ及び図４Ｂのような二重管構造の容器を備えた気液分離器１０３（ｂ）を用い、気液分離の効率を向上させてもよい。図４Ａ及び図４Ｂは、本実施形態に係るオゾン液生成器に具備される気液分離器の第３構成例を示す斜視図及び断面図である。 Further, for example, a gas-liquid separator 103 (b) provided with a container having a double tube structure as shown in FIGS. 4A and 4B may be used to improve the efficiency of gas-liquid separation. 4A and 4B are a perspective view and a cross-sectional view showing a third configuration example of the gas-liquid separator provided in the ozone liquid generator according to the present embodiment.
　図４Ａ及び図４Ｂの気液分離器１０３（ｂ）は、外壁４１に囲まれた液体や気体を貯蔵する容器部１２０を有し、容器部１２０に液体を導入する導入口１０９と、オゾン液などの液体を導出する液体導出口１１０と、気体を導出する気体循環口１１１と、液体を導出する液体循環口１１２とを備えている。なお、気液分離器１０３（ｂ）には、液体導出口１１０及び液体循環口１１２の２つの導出口を設けているが、１つの導出口により共有させた構成としてもよい。また、液体導出口１１０を利用しないオゾン液生成器の構成では、液体導出口１１０を設ける必要はない。 The gas-liquid separator 103 (b) in FIGS. 4A and 4B has a container part 120 for storing liquid or gas surrounded by an outer wall 41, an inlet 109 for introducing liquid into the container part 120, and ozone liquid. And a liquid circulation port 112 for deriving a gas, and a liquid circulation port 112 for deriving a liquid. The gas-liquid separator 103 (b) is provided with two outlets, ie, the liquid outlet 110 and the liquid circulation port 112, but may be configured to be shared by one outlet. Further, in the configuration of the ozone liquid generator that does not use the liquid outlet 110, it is not necessary to provide the liquid outlet 110.
　また、容器部１２０は、導入口１０９と連通し、内壁４２により形成された内水筒４３と外壁４１と内壁４２との間に形成され、液体を貯液可能な外水筒４４を備えた２重管構造として形成されている。気体循環口１１１は、内壁４２により形成される壁の高さよりも重力方向に沿って高い位置に設けられ、液体導出口１１０及び液体循環口１１２は、内壁４２により形成される壁の高さよりも重力方向に沿って低い位置に設けられている。ここで、気体循環口１１１は、効率的に気体を導出させるために、容器部１２０の天井近傍に設け、液体導出口１１０及び液体循環口１１２は、効率的に液体を導出させるために、容器部１２０の底面近傍に設けることがよい。 The container portion 120 communicates with the introduction port 109 and is formed between the inner water tube 43 formed by the inner wall 42, the outer wall 41, and the inner wall 42, and is provided with a double water tube 44 that can store liquid. It is formed as a tube structure. The gas circulation port 111 is provided at a position higher in the direction of gravity than the height of the wall formed by the inner wall 42, and the liquid outlet port 110 and the liquid circulation port 112 are higher than the height of the wall formed by the inner wall 42. It is provided at a low position along the direction of gravity. Here, the gas circulation port 111 is provided in the vicinity of the ceiling of the container portion 120 in order to efficiently derive gas, and the liquid outlet 110 and the liquid circulation port 112 are containers for efficiently leading out the liquid. It is good to provide near the bottom face of the part 120.
　導入口１０９から導入された液体は、容器部１２０の内水筒４３に貯液され、やがて貯液された液体の水位が内壁４２の壁の高さを超えて溢れると、外水筒４４に貯液されることとなる。その後、外水筒４４に貯液された液体は、液体導出口１１０または液体循環口１１２から導出される。このため、気液分離器１０３（ｂ）においては、容器部１２０の下層に液体が貯液され、容器部１２０の上層に気体が貯蔵されることとなる。この結果、気液分離器１０３（ｂ）は、導入口１０９から液体を導入し、気体循環口１１１から気体を導出させることが可能となる。なお、気液分離器１０３（ｂ）は、導入口１０９から導入させた液体を内壁４２に衝突させることでその流れを遮り、内水筒４３に貯液させた後に、液体導出口１１０または液体循環口１１２から導出させるため、オゾン液に含まれるオゾンガスなどの気体の気液分離をより効果的に行うことが可能となる。 The liquid introduced from the introduction port 109 is stored in the inner water cylinder 43 of the container portion 120, and when the liquid level of the stored liquid overflows beyond the height of the inner wall 42, the liquid is stored in the outer water cylinder 44. Will be. Thereafter, the liquid stored in the outer water tube 44 is led out from the liquid outlet 110 or the liquid circulation port 112. For this reason, in the gas-liquid separator 103 (b), the liquid is stored in the lower layer of the container part 120, and the gas is stored in the upper layer of the container part 120. As a result, the gas-liquid separator 103 (b) can introduce the liquid from the introduction port 109 and lead out the gas from the gas circulation port 111. The gas-liquid separator 103 (b) blocks the flow of the liquid introduced from the inlet 109 by colliding with the inner wall 42 and stores the liquid in the inner water tube 43, and then the liquid outlet 110 or the liquid circulation. Since the gas is led out from the port 112, gas-liquid separation of a gas such as ozone gas contained in the ozone liquid can be performed more effectively.
　なお、図４Ａ及び図４Ｂでは、液体導出口１１０または液体循環口１１２を気液分離器１０３（ｂ）の底面に設けているが、オゾン液を外水筒４４に貯液できるように、外水筒４４の底面と内壁４２の上部との間に位置する外壁４１に液体導出口１１０及び液体循環口１１２を設けても構わない。 4A and 4B, the liquid outlet 110 or the liquid circulation port 112 is provided on the bottom surface of the gas-liquid separator 103 (b). However, the outer water cylinder is provided so that the ozone liquid can be stored in the outer water pipe 44. The liquid outlet 110 and the liquid circulation port 112 may be provided on the outer wall 41 located between the bottom surface of 44 and the upper part of the inner wall 42.
　なお、図４Ａ及び図４Ｂでは、二重管構造により形成された気液分離器１０３（ｂ）について説明をしたが、円筒形状として構成する必要はなく、多角形状等の二重構造にしてもよく、気体と液体とを分離することが可能な構成であれば、他の構成を用いても構わない。 4A and 4B, the gas-liquid separator 103 (b) formed by the double tube structure has been described. However, the gas / liquid separator 103 (b) does not need to be configured in a cylindrical shape, and may be formed in a double structure such as a polygonal shape. Any other configuration may be used as long as it can separate the gas and the liquid.
　また、オゾン液生成器１００においては、気液分離器１０３の気体循環口１１１に開閉制御手段を設けてもよい。本実施形態に係るオゾン液生成器１００は、気体循環経路Ａに閉じ込められたオゾンガスを循環させ、オゾンガスなどの気体と液体とを混合させてオゾン液などの気液混合体を生成する。その後、気液分離器１０３で気体と液体とに分離され、このうちの液体が導出されるが、液体に溶解したオゾンガスや、一部の液体に含有するオゾンガスが気液分離器１０３の液体導出口１１０または液体循環口１１２から導出される。 Further, in the ozone liquid generator 100, an open / close control means may be provided at the gas circulation port 111 of the gas-liquid separator 103. The ozone liquid generator 100 according to the present embodiment circulates ozone gas confined in the gas circulation path A, and mixes a gas such as ozone gas and a liquid to generate a gas-liquid mixture such as ozone liquid. Thereafter, the gas-liquid separator 103 separates the gas into a liquid, and the liquid is led out. The ozone gas dissolved in the liquid or the ozone gas contained in a part of the liquid is introduced into the liquid-liquid separator 103. Derived from the outlet 110 or the liquid circulation port 112.
　このため、長時間にわたってオゾン液生成器１００を動作させた場合に、気体循環経路Ａを循環する気体が減少することにより、気液分離器１０３の水位が高くなり、気体循環口１１１から液体が溢れ出す恐れがある。そこで、開閉制御手段を設けることにより、液体が気体循環口１１１から溢れ出すことが防止できる。 For this reason, when the ozone liquid generator 100 is operated for a long time, the gas level circulating in the gas circulation path A decreases, so that the water level of the gas-liquid separator 103 is increased, and the liquid is discharged from the gas circulation port 111. There is a risk of overflow. Therefore, by providing the opening / closing control means, it is possible to prevent the liquid from overflowing from the gas circulation port 111.
　例えば、気液分離器１０３の気体循環口１１１に開閉制御手段１１９として、フロート弁を用いることが可能である。開閉制御手段を備えた気液分離器１０３（ｃ）について、図５Ａ及び図５Ｂを用いて説明する。図５Ａ及び図５Ｂは、本実施形態に係るオゾン液生成器に具備される気液分離器の第４構成例を示す上面図及び模式断面図である。 For example, a float valve can be used as the opening / closing control means 119 in the gas circulation port 111 of the gas-liquid separator 103. The gas-liquid separator 103 (c) provided with the opening / closing control means will be described with reference to FIGS. 5A and 5B. 5A and 5B are a top view and a schematic cross-sectional view showing a fourth configuration example of the gas-liquid separator provided in the ozone liquid generator according to the present embodiment.
　図５Ａ及び図５Ｂの気液分離器１０３（ｃ）は、液体や気体を密封して貯蔵可能な容器部１２０を備え、容器部１２０に液体を導入する導入口１０９と、液体を導出する液体導出口１１０と、気体を導出する気体循環口１１１と、液体を導出する液体循環口１１２と、開閉制御手段１１９ａとを有している。なお、気液分離器１０３（ｃ）には、液体導出口１１０及び液体循環口１１２の２つの導出口を設けているが、１つの導出口により共有させた構成としてもよい。また、液体導出口１１０を利用しないオゾン液生成器の構成では、液体導出口１１０を設ける必要はない。 The gas-liquid separator 103 (c) in FIGS. 5A and 5B includes a container part 120 that can store a liquid or gas in a sealed state, an inlet 109 that introduces the liquid into the container part 120, and a liquid that leads out the liquid. It has an outlet 110, a gas circulation port 111 for extracting gas, a liquid circulation port 112 for extracting liquid, and an opening / closing control means 119a. The gas-liquid separator 103 (c) is provided with two outlets, ie, the liquid outlet 110 and the liquid circulation port 112, but may be configured to be shared by one outlet. Further, in the configuration of the ozone liquid generator that does not use the liquid outlet 110, it is not necessary to provide the liquid outlet 110.
　容器部１２０は、例えば直径が３０ｍｍ～８０ｍｍ、高さが１００ｍｍ～３００ｍｍ程度の円筒形状をした密封可能な容器に、導入口から３Ｌ／ｍｉｎ程度の流量で水が導入されるように設計がなされている。気体循環口１１１は、液体導出口１１０または液体循環口１１２よりも重力方向に沿って高い位置に設けられ、気体循環口１１１には、気液分離器１０３の液面に応じて開閉制御が可能な開閉制御手段１１９ａが備えられている。 The container part 120 is designed so that water is introduced into the sealable container having a diameter of, for example, 30 mm to 80 mm and a height of about 100 mm to 300 mm from the introduction port at a flow rate of about 3 L / min. ing. The gas circulation port 111 is provided at a position higher in the direction of gravity than the liquid outlet port 110 or the liquid circulation port 112, and the gas circulation port 111 can be opened and closed in accordance with the liquid level of the gas-liquid separator 103. Open / close control means 119a is provided.
　ここで、図５Ａ及び図５Ｂの開閉制御手段１１９ａは、気液分離器１０３に貯液された液体の液面に応じて開閉制御可能なフロート弁１１９ａとして形成されている。以下、図５Ａ及び図５Ｂの開閉制御手段１１９ａをフロート弁１１９ａと呼ぶ。フロート弁は、液体より比重の小さい物質からなる物体や中空の物体などが液体に浮く浮力を利用し、液体に浮かべた物体を上下させることで開閉状態を切り替える弁のことである。一般的に、フロート弁は、タンクなどに貯液された液体の液面を一定範囲に保つように自動的に調整する水位調整手段としての役割を担う。 Here, the opening / closing control means 119a of FIGS. 5A and 5B is formed as a float valve 119a that can be controlled to open and close according to the liquid level of the liquid stored in the gas-liquid separator 103. Hereinafter, the opening / closing control means 119a of FIGS. 5A and 5B is referred to as a float valve 119a. A float valve is a valve that switches between open and closed states by using the buoyancy of an object made of a substance having a specific gravity smaller than that of a liquid or a hollow object floating on the liquid and moving the object floating on the liquid up and down. In general, the float valve plays a role as a water level adjusting means that automatically adjusts the liquid level of the liquid stored in a tank or the like so as to keep it within a certain range.
　図５Ａ及び図５Ｂのフロート弁１１９ａは、フロート１２１ａとフロートガイド１２２ａとフロート栓１２３ａとから形成される。フロート１２１ａは、気液分離器１０３に貯液される液体の比重より小さな値を有する物質からなる物体または中空の物体などにより形成され、気液分離器１０３（ｃ）に貯液された液体に浮かべられ、液面の高さに応じて上下し、液面の上昇に応じて上昇し、液面の下降に応じて下降する。 5A and 5B are formed of a float 121a, a float guide 122a, and a float plug 123a. The float 121a is formed of an object made of a substance having a value smaller than the specific gravity of the liquid stored in the gas-liquid separator 103 or a hollow object, and the liquid stored in the gas-liquid separator 103 (c). It floats up and down according to the height of the liquid level, rises as the liquid level rises, and descends as the liquid level falls.
　フロート栓１２３ａは、フロート１２１ａと接続されており、気体循環口１１１と接触し、流路を塞ぐ栓としての役割を果たすため、円錐形状、円柱状、角柱状、球状、平板状、円板状などの形状を有している。なお、フロート弁１１９ａは、フロート１２１ａとフロート栓１２３ａとを個別に形成して接続することで構成してもよいし、一体に形成しても構わない。例えば、フロート栓１２３ａを貯液槽に貯液される液体の比重より小さな値を有する物質からなる物体または中空の物体などにより形成し、流路を塞ぐ栓の役割とフロート１２１ａの役割とを兼ねさせてもよい。 The float plug 123a is connected to the float 121a and contacts the gas circulation port 111, and serves as a plug that closes the flow path, so that it has a conical shape, a cylindrical shape, a prismatic shape, a spherical shape, a flat plate shape, and a disc shape. Etc. The float valve 119a may be configured by forming and connecting the float 121a and the float plug 123a separately, or may be formed integrally. For example, the float plug 123a is formed of an object made of a substance having a value smaller than the specific gravity of the liquid stored in the liquid storage tank or a hollow object, and serves as a plug for closing the flow path and a role of the float 121a. You may let them.
　フロートガイド１２２ａは、棒線状や平板状やストラップ状などに形成され、一端が容器部１２０に接続され、もう一端がフロート１２１ａまたはフロート栓１２３ａと接続される。フロートガイド１２２ａは、気液分離器１０３（ｃ）に貯液された液面の上昇に応じてフロート１２１ａが上昇し、気体循環口１１１をフロート栓１２３ａが閉塞するように設けられている。また、液面の下降に応じてフロート１２１ａが下降し、気体循環口１１１の閉塞を解除する。 The float guide 122a is formed in a bar shape, a flat plate shape, a strap shape, or the like, one end is connected to the container portion 120, and the other end is connected to the float 121a or the float plug 123a. The float guide 122a is provided such that the float 121a rises as the liquid level stored in the gas-liquid separator 103 (c) rises, and the float plug 123a closes the gas circulation port 111. Moreover, the float 121a descends according to the descent of the liquid level, and the blockage of the gas circulation port 111 is released.
　このため、気液分離器１０３（ｃ）に貯液された液体の水位が一定の水位よりも低いときには、気体循環口１１１は開状態となり、気液分離器１０３（ｃ）に貯液された液体の水位が一定の水位以上になったときは、気体循環口１１１はフロート弁１１９ａにより塞がれ、閉状態となる。 For this reason, when the water level of the liquid stored in the gas-liquid separator 103 (c) is lower than a certain water level, the gas circulation port 111 is opened and the liquid is stored in the gas-liquid separator 103 (c). When the liquid level reaches or exceeds a certain level, the gas circulation port 111 is closed by the float valve 119a and is closed.
　例えば、図５Ａ及び図５Ｂでは、円筒形状のフロート１２１ａと円錐形状のフロート栓１２３ａとを含むフロート弁１１９ａを記載し、気液分離器１０３（ｃ）の貯液量が少なく、気体循環口１１１が開状態のときのフロート弁１１９ａを実線で示し、気液分離器１０３（ｃ）の貯液量が多く、気体循環口１１１を塞ぐ閉状態のときのフロート弁１１９ａ´を点線で示している。 For example, in FIGS. 5A and 5B, a float valve 119a including a cylindrical float 121a and a conical float plug 123a is described, and the gas-liquid separator 103 (c) has a small liquid storage amount and the gas circulation port 111. The float valve 119a when the valve is in the open state is shown by a solid line, and the float valve 119a 'when the gas-liquid separator 103 (c) has a large liquid storage amount and closes the gas circulation port 111 is shown by a dotted line. .
　フロート弁１１９ａは、気液分離器１０３（ｃ）に貯液された液面が一定量を超えると気体循環口１１１を開状態から閉状態へと切り換えるため、気体循環口１１１から一定量を超える気体または液体の流出を防止する。このため、フロート弁１１９ａは、水位センサや制御回路や電磁弁などを備えなくても動作が可能であり、低コストで小規模な構成にて気液分離器１０３に貯液された液面の調整を、自力で制御することが可能である。 The float valve 119a switches the gas circulation port 111 from the open state to the closed state when the liquid level stored in the gas-liquid separator 103 (c) exceeds a certain amount, and thus exceeds a certain amount from the gas circulation port 111. Prevent outflow of gas or liquid. For this reason, the float valve 119a can operate without a water level sensor, a control circuit, an electromagnetic valve, etc., and the liquid level stored in the gas-liquid separator 103 with a low-cost and small-scale configuration. Adjustment can be controlled by itself.
　なお、気液分離器１０３（ｃ）の形状は、円筒状や多角柱状、多角錐状、円錐形状などの一般的な形状に形成させてよく、また、気体と液体とへの気液分離の効率をあげるための装置や機構を設けてもよい。また、液体導出口１１０及び液体循環口１１２は、オゾンガスや空気などの気体が気泡として流出することを抑制するため、容器部１２０の底面近傍に設けることが好ましい。また、導出口が設けられる方向は、中心に液体が導入されるように設けられてもよいし、円周方向に液体が導入されるように設けられても構わない。なお、気体循環口１１１は、効率的に気体を導出させるために、容器部１２０の天井近傍に設けられることが好ましい。 The gas-liquid separator 103 (c) may be formed in a general shape such as a cylindrical shape, a polygonal column shape, a polygonal pyramid shape, or a conical shape. Devices and mechanisms for increasing efficiency may be provided. The liquid outlet 110 and the liquid circulation port 112 are preferably provided in the vicinity of the bottom surface of the container part 120 in order to prevent gas such as ozone gas or air from flowing out as bubbles. The direction in which the outlet is provided may be provided so that the liquid is introduced into the center or may be provided so that the liquid is introduced in the circumferential direction. In addition, it is preferable that the gas circulation port 111 is provided in the ceiling vicinity of the container part 120 in order to lead out gas efficiently.
　また、図５Ａ及び図５Ｂでは、液面の上昇に伴いフロート１２１ａが上昇し、気液分離器１０３（ｃ）内の気体循環口１１１の流路を塞ぐフロート弁を記載して説明しているが、他のフロート弁を備えた構成としてもよく、これに限定されない。 In FIGS. 5A and 5B, a float valve is described in which the float 121 a rises as the liquid level rises and closes the flow path of the gas circulation port 111 in the gas-liquid separator 103 (c). However, it is good also as a structure provided with the other float valve, and is not limited to this.
　次に、他の開閉制御手段を備えた気液分離器１０３（ｄ）の詳細について、図６Ａ及び図６Ｂを用いて説明する。図６Ａ及び図６Ｂは、本実施形態に係るオゾン液生成器に具備される気液分離器の第５構成例を示す上面図及び模式断面図である。 Next, details of the gas-liquid separator 103 (d) provided with other opening / closing control means will be described with reference to FIGS. 6A and 6B. 6A and 6B are a top view and a schematic cross-sectional view showing a fifth configuration example of the gas-liquid separator provided in the ozone liquid generator according to the present embodiment.
　図６Ａ及び図６Ｂの気液分離器１０３（ｄ）は、液体や気体を密封して貯蔵可能な容器部１２０を備え、容器部１２０に液体を導入する導入口１０９と、液体を導出する液体導出口１１０と、気体を導出する気体循環口１１１と、液体を導出する液体循環口１１２と、開閉制御手段１１９ｂとを有している。なお、気液分離器１０３（ｄ）は、液体導出口１１０及び液体循環口１１２の２つの導出口を有しているが、１つの導出口により共有させた構成としてもよい。また、液体導出口１１０を利用しないオゾン液生成器の構成では、液体導出口１１０を設ける必要はない。なお、図６Ａ及び図６Ｂの気液分離器１０３（ｄ）は、開閉制御手段１１９ｂを除き、図５Ａ及び図５Ｂの各構成要素と同一であるため、同一部分の構成要素には同一の番号を付与し、詳細な説明は繰り返さない。 The gas-liquid separator 103 (d) in FIGS. 6A and 6B includes a container portion 120 that can store liquid and gas in a sealed state, and includes an inlet 109 that introduces the liquid into the container portion 120 and a liquid that derives the liquid. It has an outlet 110, a gas circulation port 111 for extracting gas, a liquid circulation port 112 for extracting liquid, and an opening / closing control means 119b. The gas-liquid separator 103 (d) has two outlets, ie, the liquid outlet 110 and the liquid circulation port 112, but may be configured to be shared by one outlet. Further, in the configuration of the ozone liquid generator that does not use the liquid outlet 110, it is not necessary to provide the liquid outlet 110. The gas-liquid separator 103 (d) in FIGS. 6A and 6B is the same as each component in FIGS. 5A and 5B except for the opening / closing control means 119b. The detailed description will not be repeated.
　図６Ａ及び図６Ｂの開閉制御手段１１９ｂは、気液分離器１０３（ｄ）に貯液された液体の液面に応じて開閉制御可能なフロート弁１１９ｂとして形成されている。以下、図６Ａ及び図６Ｂの開閉制御手段１１９ｂをフロート弁１１９ｂと呼ぶ。 6A and 6B is formed as a float valve 119b that can be controlled to open and close according to the liquid level of the liquid stored in the gas-liquid separator 103 (d). Hereinafter, the opening / closing control means 119b shown in FIGS. 6A and 6B is referred to as a float valve 119b.
　フロート弁１１９ｂは、フロート１２１ｂとフロートガイド１２２ｂとフロート栓１２３ｂとから形成される。 The float valve 119b is formed of a float 121b, a float guide 122b, and a float plug 123b.
　フロート１２１ｂは、気液分離器１０３（ｄ）に貯液される液体の比重より小さな値を有する物質からなる物体または中空の物体などにより形成され、気液分離器１０３（ｄ）に貯液された液体に浮かべられ、液面の高さに応じて上下し、液面の上昇に応じて上昇し、液面の下降に応じて下降する。 The float 121b is formed of an object made of a substance having a value smaller than the specific gravity of the liquid stored in the gas-liquid separator 103 (d) or a hollow object, and is stored in the gas-liquid separator 103 (d). It floats on the liquid, rises and falls according to the height of the liquid level, rises as the liquid level rises, and falls as the liquid level falls.
　フロート栓１２３ｂは、気体循環口１１１と接触し、流路を塞ぐ栓としての役割を果たすため、円錐形状、円柱状、角柱状、球状、平板状、円板状などの形状をしている。 The float plug 123b contacts the gas circulation port 111 and plays a role as a plug that closes the flow path, and thus has a conical shape, a cylindrical shape, a prismatic shape, a spherical shape, a flat plate shape, a disc shape, and the like.
　フロートガイド１２２ｂは、棒線状や平板状などに形成され、一端が容器部１２０に接続され、もう一端がフロート１２１ｂと接続されている。また、フロートガイド１２２ｂには、容器部１２０との接続点とフロート１２１ｂとの接続点との間の接続間の一部または全面にフロート栓１２３ｂが設けられ、気液分離器１０３（ｄ）に貯液された液面の上昇に応じてフロート１２１ｂが上昇し、フロート栓１２３ｂが気体循環口１１１を閉塞するように設けられている。ここで、フロート１２１ｂは、必ずしもフロートガイド１２２ｂの端に設けられる必要はなく、フロートガイド１２２ｂの中間部分でフロート１２１ｂと接続されていてもよい。 The float guide 122b is formed in a bar shape or a flat plate shape, and one end is connected to the container part 120 and the other end is connected to the float 121b. In addition, the float guide 122b is provided with a float plug 123b on a part or the whole of the connection between the connection point with the container part 120 and the connection point with the float 121b, and the gas-liquid separator 103 (d) is provided with the float guide 122b. The float 121b rises in accordance with the rise in the stored liquid level, and the float plug 123b is provided to close the gas circulation port 111. Here, the float 121b is not necessarily provided at the end of the float guide 122b, and may be connected to the float 121b at an intermediate portion of the float guide 122b.
　このため、気液分離器１０３（ｄ）に貯液された液体の水位が一定の水位よりも低いときには、気体循環口１１１は開状態となり、気液分離器１０３（ｄ）に貯液された液体の水位が一定の水位以上になったときは、気体循環口１１１はフロート弁１１９ｂにより塞がれ、閉状態となる。 For this reason, when the water level of the liquid stored in the gas-liquid separator 103 (d) is lower than a certain water level, the gas circulation port 111 is opened and the liquid is stored in the gas-liquid separator 103 (d). When the liquid level reaches or exceeds a certain level, the gas circulation port 111 is closed by the float valve 119b and is closed.
　なお、フロート弁１１９ｂは、フロートガイド１２２ｂとフロート栓１２３ｂとを個別に形成して接続することで構成してもよいし、一体に形成してもよい。例えばフロートガイド１２２ｂとして、気体循環口１１１を閉塞可能なゴムのような弾力性のある素材で形成し、フロートガイド１２２ｂの役割と、流路を塞ぐフロート栓１２３ｂとしての役割とを兼ねさせてもよい。 The float valve 119b may be configured by forming and connecting the float guide 122b and the float plug 123b individually, or may be formed integrally. For example, the float guide 122b may be formed of an elastic material such as rubber capable of closing the gas circulation port 111, and may serve as the float guide 122b and the float plug 123b that closes the flow path. Good.
　例えば、図６Ａ及び図６Ｂでは、円筒状のフロート１２１ｂと平板状のフロートガイド１２２ｂと平板上のフロート栓１２３ｂとを含むフロート弁１１９ｂを記載し、気液分離器１０３（ｄ）の液面の高さが低く、気体循環口１１１が開状態のときのフロート弁１１９ｂを実線で示し、気液分離器１０３（ｄ）の液面の高さが高く、気体循環口１１１を塞ぐ閉状態のときのフロート弁１１９ｂ´を点線で示している。 For example, in FIGS. 6A and 6B, a float valve 119b including a cylindrical float 121b, a flat float guide 122b, and a flat float plug 123b is described, and the liquid level of the gas-liquid separator 103 (d) is described. The float valve 119b when the gas circulation port 111 is in the open state is indicated by a solid line, and the liquid level of the gas-liquid separator 103 (d) is high and the gas circulation port 111 is closed. The float valve 119b 'is indicated by a dotted line.
　このため、フロート弁１１９ｂは、気液分離器１０３（ｄ）に貯液された液面が一定の高さを超えると気体循環口１１１を開状態から閉状態へと切り換えるため、気体循環口１１１から一定量を超える気体または液体の流出を防止する。 For this reason, the float valve 119b switches the gas circulation port 111 from the open state to the closed state when the liquid level stored in the gas-liquid separator 103 (d) exceeds a certain height. Prevent outflow of gases or liquids above a certain amount.
　また、図６Ａ及び図６Ｂのフロート弁１１９ｂは、てこの原理を利用し、気体循環口１１１に対して、より高い押圧力をもってこれを閉塞することが可能である。すなわち、フロートガイド１２２ｂと容器部１２０との接続点を支点ｘ、フロートガイド１２２ｂとフロート１２１ｂとの接続点を力点ｙ、フロート栓１２３ｂと気体循環口１１１とが接触するフロート栓１２３ｂの接触部を作用点ｚとすることで、てこの原理の利用が可能となる。このため、低い浮力しか得られない小さなフロート１２１ｂを利用して導出口を閉状態にさせることができるため、フロート弁１１９ｂの省スペース化を図ることが可能となる。なお、てこの原理をより有効に利用するためには、力点ｙであるフロート１２１ｂは、支点ｘから可能な限り遠くに配置することがよく、例えばフロート１２１ｂはフロートガイド１２２ｂの端部に設けることがよい。また、作用点ｚであるフロート栓１２３ｂは、支点ｘから可能な限り近い位置に配置することがよいため、気体循環口１１１及びフロート栓１２３ｂは、支点ｘから可能な限り近い位置に設けることがよい。 Further, the float valve 119b shown in FIGS. 6A and 6B can use the lever principle to close the gas circulation port 111 with a higher pressing force. That is, the connection point between the float guide 122b and the container part 120 is the fulcrum x, the connection point between the float guide 122b and the float 121b is the force point y, and the contact part of the float plug 123b where the float plug 123b and the gas circulation port 111 are in contact with each other. By using the action point z, the lever principle can be used. For this reason, since the outlet port can be closed using a small float 121b that can obtain only low buoyancy, the space of the float valve 119b can be saved. In order to use the lever principle more effectively, the float 121b as the force point y is preferably arranged as far as possible from the fulcrum x. For example, the float 121b is provided at the end of the float guide 122b. Is good. Further, since the float plug 123b, which is the action point z, is preferably disposed as close as possible to the fulcrum x, the gas circulation port 111 and the float plug 123b are provided as close as possible to the fulcrum x. Good.
　図１を参照して、気体循環経路Ａは、ホースやパイプなどからなる配管系から形成され、気液分離器１０３の気体循環口１１１とオゾンガス発生器１０１の導入口１０４との間を接続する配管ａと、オゾンガス発生器１０１の導出口１０５と気液混合器１０２の導入口１０７との間を接続する配管ｂと、気液混合器１０２の導出口１０８と気液分離器１０３の導入口１０９との間を接続する配管ｃとから構成される。 Referring to FIG. 1, the gas circulation path A is formed by a piping system including a hose and a pipe, and connects between the gas circulation port 111 of the gas-liquid separator 103 and the introduction port 104 of the ozone gas generator 101. Pipe a, pipe b connecting the outlet 105 of the ozone gas generator 101 and the inlet 107 of the gas-liquid mixer 102, outlet 108 of the gas-liquid mixer 102, and inlet of the gas-liquid separator 103 109 and a pipe c connecting between the two.
　また、気体循環経路Ａは、オゾンガス発生器１０１と気液混合器１０２と気液分離器１０３とに接続され、オゾンガス発生器１０１、気液混合器１０２及び気液分離器１０３に空気やオゾンガスなどの気体を導出入させることで、オゾンガス発生器１０１に気体を循環させることができる。なお、配管ｃは、気体が液体に含有された気液混合体が流動することとなる。 The gas circulation path A is connected to the ozone gas generator 101, the gas-liquid mixer 102, and the gas-liquid separator 103, and the ozone gas generator 101, the gas-liquid mixer 102, and the gas-liquid separator 103 are connected to air, ozone gas, or the like. It is possible to circulate the gas in the ozone gas generator 101 by leading and discharging the gas. In addition, the gas-liquid mixture in which gas was contained in the liquid flows through the pipe c.
　また、配管ａは、経路の途中に開設して設けられた開設口１１７を備え、オゾン液生成器１００の内部と外部との間の、気体の流動を制御する気体流動制御手段１１８と接続させた構成にしてもよい。長時間、オゾン液生成器１００の動作をさせた際に、気体循環経路Ａ内の気体の一部は、オゾン液またはオゾン含有液として導出されるため、気体循環経路Ａ内に循環する気体量が不足する場合があるが、この構成では、オゾン液生成器１００の外部から内部へ気体を導入させることで循環する適切な気体量を維持することが可能である。 The pipe a includes an opening 117 provided in the middle of the path, and is connected to a gas flow control means 118 that controls the flow of gas between the inside and the outside of the ozone liquid generator 100. A configuration may be used. When the ozone liquid generator 100 is operated for a long time, a part of the gas in the gas circulation path A is led out as an ozone liquid or an ozone-containing liquid, so that the amount of gas circulating in the gas circulation path A However, in this configuration, it is possible to maintain an appropriate amount of gas to circulate by introducing gas from the outside to the inside of the ozone liquid generator 100.
　気体流動制御手段１１８は、配管を流動する気体の流動量を制御可能な開閉弁１１３が設けられた配管ｄにより構成される。配管ｄの一方は、配管ａの経路の途中に開設して設けられた開設口１１７と連通して接続され、もう一方には、大気または空気や酸素やオゾンガスが充填されたガスボンベなどと連通した外部口１１４が形成されている。このため、開閉弁１１３を用いて配管ｄを流動する気体の流動量を制御することによって、外部口１１４を通じた気体の流動を制御することが可能である。 The gas flow control means 118 is constituted by a pipe d provided with an on-off valve 113 capable of controlling the amount of gas flowing through the pipe. One of the pipes d is connected to and connected to an opening 117 provided in the middle of the path of the pipe a, and the other is connected to the atmosphere or a gas cylinder filled with air, oxygen, or ozone gas. An external port 114 is formed. For this reason, it is possible to control the flow of the gas through the external port 114 by controlling the flow amount of the gas flowing through the pipe d using the on-off valve 113.
　なお、開閉弁１１３は、例えば逆止弁として形成される。ここで、逆止弁は、気体や液体などの流体が流動する配管などに取り付けられ、ある方向から逆方向への流体の流れを止めるための制御弁である。逆止弁が設けられた配管は、流体を一方向にのみ流動させることが可能となる。このため、逆止弁が設けられた配管ｄは、外部口１１４から配管ａへの一方向にのみ気体を流動させるため、気体循環経路Ａから外部への気体の開放を防止することが可能である。 Note that the on-off valve 113 is formed as a check valve, for example. Here, the check valve is a control valve that is attached to a pipe or the like through which a fluid such as gas or liquid flows, and stops the flow of the fluid from a certain direction to the opposite direction. The pipe provided with the check valve can flow the fluid only in one direction. For this reason, since the pipe d provided with the check valve allows the gas to flow only in one direction from the external port 114 to the pipe a, it is possible to prevent the gas from being released from the gas circulation path A to the outside. is there.
　なお、図１においては、配管ｄが配管ａに連通して接続されているが、これを配管ｂに連通させて接続してもよい。また、気体流動制御手段１１８は、オゾン液生成器１００の内部と外部との間の気体の流動を制御可能な手段であればよく、配管ａの開設口１１７に配管を介さず逆止弁を備えた構成としても構わない。また、逆止弁の代わりにオゾン液生成器１００への導入を制御可能な開閉バルブや電子的に制御が可能な電磁バルブ等によりこれを構成してもよい。 In FIG. 1, the pipe d is connected to the pipe a, but it may be connected to the pipe b. Further, the gas flow control means 118 may be any means that can control the gas flow between the inside and the outside of the ozone liquid generator 100, and a check valve is not connected to the opening 117 of the pipe a without a pipe. It does not matter as a configuration provided. Moreover, you may comprise this by the opening / closing valve which can control introduction to the ozone liquid generator 100 instead of a non-return valve, the electromagnetic valve which can be controlled electronically, etc.
　また、配管ｄには、オゾンガスを還元する機能を有するオゾンフィルタを設けてもよい。オゾンフィルタは、フィルタを通るオゾンガスを分解することが可能なため、外部口１１４からオゾンガスを導出する場合に、分解した後の気体を放出することができる。ここで、オゾンフィルタとしては、オゾン分解触媒を格子状に構成した紙やアルミニウム付着させたものなど、一般的なオゾンフィルタを配置する。 Further, an ozone filter having a function of reducing ozone gas may be provided in the pipe d. Since the ozone filter can decompose the ozone gas that passes through the filter, when the ozone gas is led out from the external port 114, the decomposed gas can be released. Here, as the ozone filter, a general ozone filter such as a paper in which an ozone decomposition catalyst is configured in a lattice shape or aluminum is attached is disposed.
　なお、オゾン液生成器１００において、循環する気体量の不足を考慮する必要がない場合には、気体流動制御手段１１８を設けない構成により、オゾン液を生成することも当然に可能である。 In addition, in the ozone liquid generator 100, when it is not necessary to consider the shortage of the circulating gas amount, it is naturally possible to generate the ozone liquid by a configuration in which the gas flow control means 118 is not provided.
　液体循環経路Ｂ１は、ホースやパイプなどからなる配管系から形成され、気液分離器１０３の液体循環口１１２と貯液槽１１５との間を接続する配管ｅと、貯液槽１１５と気液混合器１０２の導入口１０６との間を接続する配管ｆと、気液混合器１０２の導出口１０８と気液分離器１０３との間を接続する配管ｃとから構成される。 The liquid circulation path B1 is formed by a piping system including a hose, a pipe, and the like, a pipe e connecting the liquid circulation port 112 of the gas-liquid separator 103 and the liquid storage tank 115, the liquid storage tank 115 and the gas liquid. The pipe f is connected between the inlet 106 of the mixer 102 and the pipe c is connected between the outlet 108 of the gas-liquid mixer 102 and the gas-liquid separator 103.
　また、液体循環経路Ｂ１は、気液混合器１０２と気液分離器１０３と貯液槽１１５とに接続され、気液混合器１０２、気液分離器１０３及び貯液槽１１５にオゾン液などの液体を導出入させることで、気液混合器１０２に液体を循環させることができる。また、液体循環経路Ｂ１は、液体や気体を圧送可能なポンプなどからなる圧送手段１１６を備えている。ここで、圧送手段１１６は、配管ｆに設けられているが、その配置位置は、配管ｆに限られるものではない。 Further, the liquid circulation path B1 is connected to the gas-liquid mixer 102, the gas-liquid separator 103, and the liquid storage tank 115, and ozone gas or the like is supplied to the gas-liquid mixer 102, the gas-liquid separator 103, and the liquid storage tank 115. The liquid can be circulated through the gas-liquid mixer 102 by introducing the liquid. Further, the liquid circulation path B1 includes a pressure feeding unit 116 including a pump capable of pumping liquid or gas. Here, the pressure feeding means 116 is provided in the pipe f, but the arrangement position thereof is not limited to the pipe f.
　また、配管ｅには、第２の開閉弁Ｖ２が設けられ、これにより配管ｅを流動する液体の導出量を制御することができる。 Also, the pipe e is provided with a second on-off valve V2, whereby the amount of liquid flowing through the pipe e can be controlled.
　次に、気体循環経路Ａに対して、図５Ａ及び図５Ｂまたは図６Ａ及び図６Ｂなどの開閉制御手段１１９が設けられた気液分離器１０３と、逆止弁を有する気体流動制御手段１１８とが接続されたオゾン液生成器１００の構成について説明する。上述の構成でオゾン液生成の動作を行った場合、自動的にオゾン液生成器１００内へ気体の吸引が可能となる。以下において、自動的に気体を吸引する動作原理について、第１の開閉弁Ｖ１を閉状態とし、第２の開閉弁Ｖ２を開状態とし、オゾンガス発生器１０１を動作させ、液体循環経路Ｂ１に液体を循環させた際の動作に基づいて説明する。オゾン液生成器１００を動作させると、気体循環経路Ａは、気液分離器１０３に貯液された液体と気液混合器１０２の液体との間に閉じ込められ、いわゆる密封状態となる。 Next, with respect to the gas circulation path A, the gas-liquid separator 103 provided with the opening / closing control means 119 such as FIGS. 5A and 5B or FIGS. 6A and 6B, and the gas flow control means 118 having a check valve, The configuration of the ozone liquid generator 100 to which is connected will be described. When the operation of generating the ozone liquid is performed with the above-described configuration, the gas can be automatically sucked into the ozone liquid generator 100. In the following, regarding the operation principle of automatically sucking gas, the first on-off valve V1 is closed, the second on-off valve V2 is opened, the ozone gas generator 101 is operated, and the liquid circulation path B1 is liquidated. A description will be given based on the operation when the is circulated. When the ozone liquid generator 100 is operated, the gas circulation path A is confined between the liquid stored in the gas-liquid separator 103 and the liquid in the gas-liquid mixer 102 and is in a so-called sealed state.
　ここで、密封状態には、物理的に密封された空間だけではなく、気体が液体により閉じ込められた空間も含まれる意味として使用する。例えば、オゾン液生成器１００の気体循環経路Ａに気体を封止することができれば、常時、液体導出口１１０または液体循環口１１２から液体が導出されていても密封状態として表現する。 Here, the sealed state is used to mean not only a physically sealed space but also a space in which a gas is confined by a liquid. For example, if the gas can be sealed in the gas circulation path A of the ozone liquid generator 100, the liquid is always expressed as a sealed state even if the liquid is led out from the liquid outlet 110 or the liquid circulation port 112.
　この状態で長時間にわってオゾン液生成器１００を利用した場合には、気体循環経路Ａ及び気液分離器１０３の気体は液体に混合された後、オゾン液生成器１００の外部に導出されるため、気体循環経路Ａ及び気液分離器１０３の気体量は減少する。やがて気液分離器１０３の液体の貯液量が増加することにより、開閉制御手段１１９が自動的に気体循環口１１１を閉塞させる。この結果、気液分離器１０３の気体循環口１１１から導出される気体の流動が止まり、負圧になっている気体循環経路Ａに対して外部口１１４から逆止弁を通り気体が導入される。これは、気液混合器１０２の吸引力により負圧状態となっている気体循環経路Ａに送られていた気体が開閉制御手段１１９により物理的に遮断されることになるため、代わりに外部口１１４から気体が吸引されることになるためである。 When the ozone liquid generator 100 is used for a long time in this state, the gas in the gas circulation path A and the gas-liquid separator 103 is mixed with the liquid and then led out of the ozone liquid generator 100. Therefore, the gas amount in the gas circulation path A and the gas-liquid separator 103 decreases. Eventually, as the amount of liquid stored in the gas-liquid separator 103 increases, the open / close control means 119 automatically closes the gas circulation port 111. As a result, the flow of the gas led out from the gas circulation port 111 of the gas-liquid separator 103 stops, and the gas is introduced from the external port 114 through the check valve to the gas circulation path A that is in a negative pressure. . This is because the gas sent to the gas circulation path A, which is in a negative pressure state by the suction force of the gas-liquid mixer 102, is physically blocked by the opening / closing control means 119. This is because gas is sucked from 114.
　貯液槽１１５は、液体や気体が貯蔵できる密封可能な容器などから形成され、一方が配管ｅと接続され、もう一方が配管ｆと接続されている。また、貯液槽１１５は、配管ｅを介して導入されるオゾン液などの液体を貯液し、貯液された液体を配管ｆを介して導出する。 The liquid storage tank 115 is formed from a sealable container or the like that can store liquid or gas, and one is connected to the pipe e and the other is connected to the pipe f. The liquid storage tank 115 stores a liquid such as ozone liquid introduced through the pipe e, and guides the stored liquid through the pipe f.
　なお、貯液槽１１５は、オゾン液生成器１００の外部から液体を給水する給水口と貯液された高濃度のオゾン液や水などの液体を出水口を設けてもよい。ここで、貯液槽１１５の一構成例を、図７Ａ及び図７Ｂを用いて説明する。図７Ａ及び図７Ｂは、本実施形態に係るオゾン液生成器に具備される貯液槽の斜視図および断面図である。 In addition, the liquid storage tank 115 may be provided with a water supply port for supplying liquid from the outside of the ozone liquid generator 100 and a water outlet for liquid such as high-concentration ozone liquid or water stored. Here, a configuration example of the liquid storage tank 115 will be described with reference to FIGS. 7A and 7B. 7A and 7B are a perspective view and a cross-sectional view of a liquid storage tank provided in the ozone liquid generator according to the present embodiment.
　図７Ａ及び図７Ｂに示す貯液槽１１５（ａ）には、水やオゾン液などの液体を貯蔵する容器部７５と、配管ｅに接続され、液体を導入する導入口７１と、配管ｆに接続され、液体を導出する導出口７２と、オゾン液を生成するために必要な水をオゾン液生成器１００の外部から給水する給水口７３と、オゾン液生成器１００の外部へオゾン液や水などの液体を導出する出水口７４とが設けられている。貯液槽１１５（ａ）においては、循環するオゾン液を容器部７５に貯液することが可能であるため、高濃度のオゾン液を貯液して使用することが可能である。また、給水口７３には、開閉弁が設けられ、開閉弁を閉じて密封状態にすることで内部の気体の流出を防止することが可能である。また、出水口７４には、開閉弁が設けられ、開閉弁を制御することで液体の導出量を制御することが可能である。 In the liquid storage tank 115 (a) shown in FIGS. 7A and 7B, a container part 75 for storing liquid such as water or ozone liquid, an inlet 71 for introducing liquid connected to the pipe e, and a pipe f are connected. A lead-out port 72 connected to lead out the liquid, a water supply port 73 for supplying water necessary for generating the ozone liquid from the outside of the ozone liquid generator 100, and an ozone liquid and water to the outside of the ozone liquid generator 100. And a water outlet 74 for leading out a liquid such as the above. In the liquid storage tank 115 (a), since the circulating ozone liquid can be stored in the container part 75, it is possible to store and use a high-concentration ozone liquid. Further, the water supply port 73 is provided with an open / close valve, and the internal gas can be prevented from flowing out by closing and closing the open / close valve. Further, the water outlet 74 is provided with an opening / closing valve, and the amount of liquid discharged can be controlled by controlling the opening / closing valve.
　ここで、導入口７１、導出口７２、給水口７３及び出水口７４に関する貯液槽１１５（ａ）への配置は、特に限定されるものではないが、導入口７１及び給水口７３は、貯液槽１１５（ａ）の液体の逆流を防ぐために、貯液槽１１５（ａ）の上層部に設けられることがよく、導出口７２及び出水口７４は、貯液槽１１５（ａ）の下層部に設けられることがよい。 Here, the arrangement of the introduction port 71, the outlet port 72, the water supply port 73, and the water outlet 74 in the liquid storage tank 115 (a) is not particularly limited. In order to prevent the backflow of the liquid in the liquid tank 115 (a), it is preferable to be provided in the upper layer part of the liquid tank 115 (a), and the outlet 72 and the water outlet 74 are the lower part of the liquid tank 115 (a). It is good to be provided.
　なお、オゾン液生成器１００に上述した構成の貯液槽１１５（ａ）を設ける場合には、オゾン液を出水口７４からオゾン液生成器１００の外部に導出することが可能になるため、気液分離器１０３に液体導出口１１０を設ける必要はない。そのため、その場合には、気液分離器１０３には、例えば導入口１０９と気体循環口１１１と液体循環口１１２とだけを設けた構成にしてもよい。 When the liquid storage tank 115 (a) having the above-described configuration is provided in the ozone liquid generator 100, the ozone liquid can be led out of the ozone liquid generator 100 from the water outlet 74. It is not necessary to provide the liquid outlet 110 in the liquid separator 103. Therefore, in that case, the gas-liquid separator 103 may be provided with, for example, only the introduction port 109, the gas circulation port 111, and the liquid circulation port 112.
　＜動作説明＞
　次に、本実施形態に係るオゾン液生成器１００の動作について、図１から図７Ｂを用いて説明する。ここで、開閉弁の開状態は、流体が開閉弁を流動可能な状態を意味し、閉状態は、流体が開閉弁により遮断され、流体の流動が停止された状態を意味するものとして説明する。 <Description of operation>
Next, operation | movement of the ozone liquid generator 100 which concerns on this embodiment is demonstrated using FIGS. 1-7B. Here, the open state of the on-off valve means that the fluid can flow through the on-off valve, and the closed state means that the fluid is blocked by the on-off valve and the fluid flow is stopped. .
　オゾン液生成器１００は、オゾン液の生成時に、高濃度のオゾン液を生成し、オゾン液の導出時に、生成した高濃度のオゾン液を導出する。 The ozone liquid generator 100 generates a high concentration ozone liquid when the ozone liquid is generated, and derives the generated high concentration ozone liquid when the ozone liquid is derived.
　オゾン液生成器１００による高濃度のオゾン液の生成時には、第１の開閉弁Ｖ１を閉状態にし、第２の開閉弁Ｖ２を開状態にし、オゾンガス発生器１０１を動作させ、圧送手段１１６により、貯液槽１１５から液体を気液混合器１０２へ導入する。 When the ozone liquid generator 100 generates high-concentration ozone liquid, the first on-off valve V1 is closed, the second on-off valve V2 is opened, the ozone gas generator 101 is operated, and the pressure feeding means 116 A liquid is introduced from the liquid storage tank 115 into the gas-liquid mixer 102.
　気液混合器１０２の導入口１０６から導入された液体は、もう一方の導入口１０７から導入されたオゾンガスと混合され、オゾン液が生成される。ここで、導入口１０７から導入されるオゾンガスは、オゾンガス発生器１０１により生成されたものである。生成されたオゾン液は、その後、配管ｃを介して、気液分離器１０３に導入されて貯液される。ここで、オゾン液には、液体にオゾンガスが溶け込んだオゾン溶液や液体にオゾンガスが気泡として含有されるオゾン含有液が含まれているため、気液分離器１０３の下層にオゾン溶液が貯液され、上層にオゾンガスや空気などを含む気体が貯蔵される。このため、気液分離器１０３においては、オゾンガスや空気などを含む気体とオゾン溶液を含む液体とに気液分離することが可能となる。 The liquid introduced from the inlet 106 of the gas-liquid mixer 102 is mixed with the ozone gas introduced from the other inlet 107 to generate an ozone liquid. Here, the ozone gas introduced from the inlet 107 is generated by the ozone gas generator 101. The generated ozone liquid is then introduced into the gas-liquid separator 103 via the pipe c and stored. Here, since the ozone liquid contains an ozone solution in which ozone gas is dissolved in the liquid and an ozone-containing liquid in which the ozone gas is contained in the liquid as bubbles, the ozone solution is stored in the lower layer of the gas-liquid separator 103. A gas containing ozone gas or air is stored in the upper layer. For this reason, in the gas-liquid separator 103, it becomes possible to perform gas-liquid separation into a gas containing ozone gas or air and a liquid containing an ozone solution.
　分離されたオゾンガスや空気を含む気体は、配管ａを介して、オゾンガス発生器１０１に導入され、オゾンガス発生器１０１において、オゾンガスを含有する気体を原料にオゾンガスが発生させられる。このため、空気や酸素を原料に発生した場合に比べ、より高濃度のオゾンガスの生成が可能となる。 The separated gas containing ozone gas and air is introduced into the ozone gas generator 101 via the pipe a, and the ozone gas generator 101 generates ozone gas using the gas containing the ozone gas as a raw material. For this reason, compared with the case where air or oxygen is generated in the raw material, it is possible to generate ozone gas having a higher concentration.
　また、気体循環経路Ａ内の気体は、気液分離器１０３に貯液された液体と気液混合器１０２の液体とにより閉じ込められたいわゆる密封状態になっているため、水圧の影響を受けて圧縮された加圧状態となる。このため、オゾンガス発生器１０１または気液混合器１０２に高密度の気体を導入することが可能となるため、オゾンガス発生器１０１により高密度の気体に基づく、より高濃度のオゾンガスが発生させられ、気液混合器１０２により高密度のオゾンガスに基づく、効率的な気液混合効果が得られることになり、飛躍的に高い濃度のオゾン液を生成することが可能となる。 Further, since the gas in the gas circulation path A is in a so-called sealed state confined by the liquid stored in the gas-liquid separator 103 and the liquid in the gas-liquid mixer 102, it is affected by the water pressure. The compressed pressure state is obtained. For this reason, since it becomes possible to introduce a high-density gas into the ozone gas generator 101 or the gas-liquid mixer 102, a higher-concentration ozone gas based on the high-density gas is generated by the ozone gas generator 101, An efficient gas-liquid mixing effect based on high-density ozone gas can be obtained by the gas-liquid mixer 102, and it becomes possible to generate ozone liquid having a drastically high concentration.
　ここで、密封状態には、物理的に密封された空間だけではなく、気体が液体により閉じ込められた空間も含まれる意味として使用する。例えば、オゾン液生成器１００の気体循環経路Ａに気体を封止することができれば、常時、液体導出口１１０または液体循環口１１２から液体が導出されていても密封状態として表現する。 Here, the sealed state is used to mean not only a physically sealed space but also a space in which a gas is confined by a liquid. For example, if the gas can be sealed in the gas circulation path A of the ozone liquid generator 100, the liquid is always expressed as a sealed state even if the liquid is led out from the liquid outlet 110 or the liquid circulation port 112.
　その後、生成されたオゾンガスは、再び気液混合器１０２に導入され、気体循環経路Ａにて再び循環することになる。すなわち、生成されたオゾンガスは、気液混合器１０２、配管ｃ、気液分離器１０３、配管ａ、オゾンガス発生器１０１、配管ｂ、気液混合器１０２、配管ｃ、気液分離器１０３、・・・の順で繰り返し循環することになる。この結果、オゾンガス発生器１０１は、水に溶けきれず、気液分離されたオゾンガスを含有する気体をもとに、これを循環させてオゾン液を生成することになるため、より高濃度のオゾン液が生成されることとなる。 Thereafter, the generated ozone gas is again introduced into the gas-liquid mixer 102 and is circulated again in the gas circulation path A. That is, the generated ozone gas is gas-liquid mixer 102, pipe c, gas-liquid separator 103, pipe a, ozone gas generator 101, pipe b, gas-liquid mixer 102, pipe c, gas-liquid separator 103,. It will cycle repeatedly in the order. As a result, the ozone gas generator 101 does not dissolve in water and circulates it based on the gas containing the gas-liquid separated ozone gas to generate ozone liquid. A liquid will be produced.
　一方、気液分離器１０３により気液分離されたオゾン液は、配管ｅを介して貯液槽１１５に導入され、貯液される。その後、貯液されたオゾン液は、再び気液混合器１０２に導入され、液体循環経路Ｂ１にて再び循環することになる。すなわち、気液分離されたオゾン液は、気液分離器１０３、配管ｅ、貯液槽１１５、配管ｆ、気液混合器１０２、配管ｃ、気液分離器１０３、配管ｅ、貯液槽１１５、配管ｆ、気液混合器１０２、・・・の順で繰り返し循環することになる。この結果、貯液槽１１５に貯液されたオゾン液または液体循環経路Ｂ１を循環するオゾン液は、気液混合器１０２に繰り返し循環されることになるため、混合効率が向上し、より高濃度のオゾン液が生成されることとなる。 On the other hand, the ozone liquid separated by the gas-liquid separator 103 is introduced into the liquid storage tank 115 through the pipe e and stored. Thereafter, the stored ozone liquid is again introduced into the gas-liquid mixer 102 and is circulated again in the liquid circulation path B1. That is, the gas-liquid separated ozone liquid is gas-liquid separator 103, pipe e, liquid storage tank 115, pipe f, gas-liquid mixer 102, pipe c, gas-liquid separator 103, pipe e, liquid storage tank 115. , Piping f, gas-liquid mixer 102,... As a result, the ozone liquid stored in the liquid storage tank 115 or the ozone liquid circulating in the liquid circulation path B1 is repeatedly circulated to the gas-liquid mixer 102, so that the mixing efficiency is improved and the concentration is higher. The ozone liquid will be generated.
　次に、オゾン液生成器１００によるオゾン液の導出時について説明する。オゾン液生成器１００によるオゾン液の導出時には、第１の開閉弁Ｖ１を開状態にし、第２の開閉弁Ｖ２を閉状態にする。なお、オゾンガス発生器１０１は、動作させてもよいし、停止させてもよい。 Next, the time when the ozone liquid is derived by the ozone liquid generator 100 will be described. When the ozone liquid is derived by the ozone liquid generator 100, the first on-off valve V1 is opened and the second on-off valve V2 is closed. The ozone gas generator 101 may be operated or stopped.
　開閉弁を切り替えると、貯液槽１１５に貯液された高濃度のオゾン液は、気液混合器１０２を通って気液分離器１０３に導入され、気液分離器１０３の液体導出口１１０からオゾン液が導出される。なお、貯液槽１１５として図７Ａ及び図７Ｂの貯液槽１１５（ａ）を設けた場合には、オゾン液の導出時に、貯液槽１１５（ａ）の出水口７４を開状態にさせることでオゾン液を導出させてもよい。このとき、貯液槽１１５（ａ）の出水口７４は、気液分離器１０３の液体導出口１１０と同じ役割を担うため、気液分離器１０３に液体導出口１１０を設けない構成のオゾン液生成器としても構わない。例えば、気液分離器１０３は、導入口１０９と気体循環口１１１と液体循環口１１２とのみを備えた構成にしてもよい。 When the on-off valve is switched, the high-concentration ozone liquid stored in the liquid storage tank 115 is introduced into the gas-liquid separator 103 through the gas-liquid mixer 102 and from the liquid outlet 110 of the gas-liquid separator 103. Ozone liquid is derived. When the liquid storage tank 115 (a) of FIGS. 7A and 7B is provided as the liquid storage tank 115, the outlet 74 of the liquid storage tank 115 (a) is opened when the ozone liquid is derived. The ozone liquid may be led out. At this time, since the water outlet 74 of the liquid storage tank 115 (a) plays the same role as the liquid outlet 110 of the gas-liquid separator 103, the ozone liquid having a configuration in which the liquid outlet 110 is not provided in the gas-liquid separator 103. It does not matter as a generator. For example, the gas-liquid separator 103 may be configured to include only the introduction port 109, the gas circulation port 111, and the liquid circulation port 112.
　また、オゾン液の生成時とオゾン液の導出時との切り替えは、開閉弁を手動において切り替えてもよく、また、制御手段を設け、あらかじめプログラムされたタイミングやタイマーやオゾン液の濃度を検出するセンサなどを用いて制御してもよい。 In addition, switching between the time of ozone liquid generation and the time of ozone liquid derivation may be performed manually by switching the on-off valve, and a control means is provided to detect a preprogrammed timing, timer or ozone liquid concentration. You may control using a sensor etc.

Next, an experimental example in which an ozone liquid is generated using the ozone liquid generator 100 described above will be described with reference to FIG. FIG. 8 is a diagram showing experimental results of ozone water generated by the ozone liquid generator according to this embodiment.
　実験例１においては、１００ｍｇ／ｈのオゾンガスを発生する能力を有するオゾンガス発生器１０１と、１０Ｌの水を貯液した貯液槽１１５と、圧送手段として水圧７６ＫＰａ、流量２．３Ｌ／ｍｉｎの液体の圧送が可能なポンプとを利用したオゾン液生成器１００の構成において、生成されるオゾン液のオゾン濃度を測定した。ここで、オゾン液生成器１００の内部、すなわち気体循環経路Ａ、オゾンガス発生器１０１、気液混合器１０２及び気液分離器１０３に含まれる空気容量は、１４．５Ｌであった。なお、実験環境は、室温２２．５℃、湿度８９％、水温２２．９℃の環境のもととした。 In Experimental Example 1, an ozone gas generator 101 capable of generating 100 mg / h of ozone gas, a liquid storage tank 115 storing 10 L of water, and a liquid having a water pressure of 76 KPa and a flow rate of 2.3 L / min as pressure feeding means. In the configuration of the ozone liquid generator 100 using a pump capable of pumping, the ozone concentration of the generated ozone liquid was measured. Here, the volume of air contained in the ozone liquid generator 100, that is, in the gas circulation path A, the ozone gas generator 101, the gas-liquid mixer 102, and the gas-liquid separator 103 was 14.5L. The experimental environment was a room temperature of 22.5 ° C., a humidity of 89%, and a water temperature of 22.9 ° C.
　実験例２においては、１００ｍｇ／ｈのオゾンガスを発生する能力を有するオゾンガス発生器１０１を２つ直列に接続させ、１０Ｌの水を貯液した貯液槽１１５と、圧送手段として水圧７４ＫＰａ、流量２．３Ｌ／ｍｉｎの液体の圧送が可能なポンプとを利用したオゾン液生成器１００の構成において、生成されるオゾン液のオゾン濃度を測定した。ここで、オゾン液生成器１００の内部、すなわち気体循環経路Ａ、オゾンガス発生器１０１、気液混合器１０２及び気液分離器１０３に含まれる空気容量は、１４．５Ｌであった。なお、実験環境は室温２１．３℃、湿度８５％、水温２１．３℃の環境のもととした。 In Experimental Example 2, two ozone gas generators 101 having the ability to generate 100 mg / h ozone gas are connected in series, a liquid storage tank 115 storing 10 L of water, a water pressure of 74 KPa as a pressure feeding means, a flow rate of 2 In the configuration of the ozone liquid generator 100 using a pump capable of pumping a liquid of 3 L / min, the ozone concentration of the generated ozone liquid was measured. Here, the volume of air contained in the ozone liquid generator 100, that is, the gas circulation path A, the ozone gas generator 101, the gas-liquid mixer 102, and the gas-liquid separator 103 was 14.5L. The experimental environment was a room temperature of 21.3 ° C., a humidity of 85%, and a water temperature of 21.3 ° C.
　図８においては、縦軸がオゾン水のオゾン濃度（ｍｇ／ｈ）を示しており、横軸が経過時間（ｓｅｃ）を示している。 In FIG. 8, the vertical axis indicates the ozone concentration (mg / h) of the ozone water, and the horizontal axis indicates the elapsed time (sec).
　実験の結果、実験例１及び実験例２ともに、経過時間とともにオゾン水のオゾン濃度は上昇し、オゾン液生成器１００が有するオゾン濃度能力に飽和していく状況が把握できる。また、オゾンガス発生器を２個にしてオゾン発生能力を倍増させた実験例２では、実験例１に比べ１．６倍のオゾン濃度を有するオゾン水の生成を実現している。このため、本実施形態に係るオゾン液生成器１００においては、オゾンガス発生器１０１のオゾンガスの発生能力を高めた際にも、オゾンガス発生器１０１の発生能力に応じて高濃度のオゾン液を生成することが可能になることが確認された。 As a result of the experiment, in both Experimental Example 1 and Experimental Example 2, it is possible to grasp the situation in which the ozone concentration of the ozone water increases with the elapsed time and is saturated with the ozone concentration capability of the ozone liquid generator 100. Further, in Experimental Example 2 in which the ozone generating capacity is doubled by using two ozone gas generators, the generation of ozone water having an ozone concentration 1.6 times that in Experimental Example 1 is realized. Therefore, in the ozone liquid generator 100 according to the present embodiment, even when the ozone gas generation capacity of the ozone gas generator 101 is increased, a high concentration ozone liquid is generated according to the generation capacity of the ozone gas generator 101. It was confirmed that it would be possible.
　（実施形態２）
　次に、本発明の実施形態２について、図９を用いて説明する。図９は、本発明の実施形態２に係るオゾン液生成器の概略図である。なお、上述した実施形態１のオゾン液生成器１００と同一部分の各構成要素には同一の番号を付与し、詳細な説明を繰り返さない。 (Embodiment 2)
Next, Embodiment 2 of the present invention will be described with reference to FIG. FIG. 9 is a schematic view of an ozone liquid generator according to Embodiment 2 of the present invention. In addition, the same number is provided to each component of the same part as the ozone liquid generator 100 of Embodiment 1 mentioned above, and detailed description is not repeated.
　図９のオゾン液生成器２００は、オゾンガスを発生するオゾンガス発生器１０１と、オゾンガスと液体とを混合する気液混合器１０２と、液体に気体が含有した気体含有液を気体と液体とに分離する気液分離器１０３と、気液混合器１０２またはオゾンガス発生器１０１に気体を循環させる気体循環経路Ａと、気液混合器１０２に液体を循環させる液体循環経路Ｂ２と、液体循環経路Ｂ２に設けられた液体を圧送可能な圧送手段１１６とを備えている。 The ozone liquid generator 200 in FIG. 9 separates an ozone gas generator 101 that generates ozone gas, a gas-liquid mixer 102 that mixes ozone gas and liquid, and a gas-containing liquid containing gas in liquid into gas and liquid. Gas-liquid separator 103, gas-circulation path A for circulating gas to gas-liquid mixer 102 or ozone gas generator 101, liquid-circulation path B2 for circulating liquid to gas-liquid mixer 102, and liquid-circulation path B2 And a pumping means 116 capable of pumping the provided liquid.
　オゾン液生成器２００の気体循環経路Ａは、オゾンガス発生器１０１と気液混合器１０２と気液分離器１０３とに接続され、オゾンガスを含有する気体を循環させることで、高濃度のオゾンガスを生成する。一方、液体循環経路Ｂ２は、気液混合器１０２と気液分離器１０３とに接続され、オゾン液などの液体を循環し、気液混合器１０２で生成させたオゾンガスと混合させることで、高濃度のオゾン液を生成する。生成された高濃度のオゾン液は、気液分離器１０３または液体循環経路Ｂ２に貯液され、洗浄、殺菌、消臭などの用途に利用するためにオゾン液生成器２００外に導出させる。なお、オゾン液生成器２００は、様々な製品、例えば、浄水器、トイレ用、医療用などの製品に組み込まれて利用することが可能である。 The gas circulation path A of the ozone liquid generator 200 is connected to the ozone gas generator 101, the gas-liquid mixer 102, and the gas-liquid separator 103, and generates a high-concentration ozone gas by circulating a gas containing ozone gas. To do. On the other hand, the liquid circulation path B2 is connected to the gas-liquid mixer 102 and the gas-liquid separator 103, circulates a liquid such as ozone liquid, and mixes it with the ozone gas generated by the gas-liquid mixer 102. Produces ozone liquid with a concentration. The generated high-concentration ozone liquid is stored in the gas-liquid separator 103 or the liquid circulation path B2, and is led out of the ozone liquid generator 200 to be used for cleaning, sterilization, deodorization, and the like. The ozone liquid generator 200 can be used by being incorporated into various products such as water purifiers, toilets, and medical products.
　気液分離器１０３は、導入された気体を含有する気体含有液を気体と液体とに分離して導出することが可能であり、例えば密封可能な容器などから形成される。気液分離器１０３は、配管ｃに接続され、液体を導入する導入口１０９と、オゾン液生成器２００の外部へ水やオゾン液などの液体を導出する液体導出口１１０と、配管ａに接続され、空気やオゾンガスなどの気体を循環させるための気体循環口１１１と、配管ｅに接続され、水やオゾン液などの液体を循環させるための液体循環口１１２とを備えている。なお、気液分離器１０３に生成したオゾン液を貯液させる場合は、オゾン液の使用量にあわせて気液分離器１０３の大きさを適宜変更させ、貯液許容量を変更する必要がある。 The gas-liquid separator 103 can separate the gas-containing liquid containing the introduced gas into a gas and a liquid, and is formed from, for example, a sealable container. The gas-liquid separator 103 is connected to the pipe c, connected to the inlet 109 for introducing the liquid, the liquid outlet 110 for leading the liquid such as water and ozone liquid to the outside of the ozone liquid generator 200, and the pipe a. And a gas circulation port 111 for circulating a gas such as air or ozone gas, and a liquid circulation port 112 connected to the pipe e for circulating a liquid such as water or ozone liquid. In addition, when storing the produced | generated ozone liquid in the gas-liquid separator 103, it is necessary to change the magnitude | size of the gas-liquid separator 103 suitably according to the usage-amount of ozone liquid, and to change a liquid storage allowance. .
　図９の液体循環経路Ｂ２は、ホースやパイプなどからなる配管系から形成され、気液分離器１０３の液体循環口１１２と気液混合器１０２の導入口１０６との間を接続する配管ｅ及び配管ｆと、気液混合器１０２の導出口１０８と気液分離器１０３の導入口１０９との間を接続する配管ｃとから構成される。 The liquid circulation path B2 in FIG. 9 is formed by a piping system including a hose, a pipe, and the like, and a pipe e and a pipe e that connect between the liquid circulation port 112 of the gas-liquid separator 103 and the introduction port 106 of the gas-liquid mixer 102. The pipe f is constituted by a pipe c connecting the outlet 108 of the gas-liquid mixer 102 and the inlet 109 of the gas-liquid separator 103.
　また、液体循環経路Ｂ２は、気液混合器１０２と気液分離器１０３とに接続され、気液混合器１０２及び気液分離器１０３にオゾン液などの液体を導出入させることで、気液混合器１０２に液体を循環させることができる。なお、図９では、配管ｅと配管ｆとが連通して接続された構成を示しているが、単一の配管にて構成させても構わない。また、液体循環経路Ｂ２は、液体や気体を圧送可能なポンプなどからなる圧送手段１１６を備え、液体循環経路Ｂ２に液体を循環させることが可能である。また、圧送手段１１６は、配管ｆに設けられているが、その配置位置は、配管ｆに限られるものではなく、配管ｅなどに配置しても構わない。また、液体循環経路Ｂ２は、オゾン液生成器２００の外部へ液体の導出入が可能な外部口１２４を有する配管ｇと接続されている。配管ｇには、第３の開閉弁Ｖ３が設けれ、これにより配管ｇを流動する液体の流動量を制御することが可能である。 Further, the liquid circulation path B2 is connected to the gas-liquid mixer 102 and the gas-liquid separator 103, and a liquid such as ozone liquid is led into and out of the gas-liquid mixer 102 and the gas-liquid separator 103. A liquid can be circulated through the mixer 102. Although FIG. 9 shows a configuration in which the piping e and the piping f are connected in communication, they may be configured by a single piping. In addition, the liquid circulation path B2 includes a pressure feeding unit 116 including a pump capable of pumping liquid or gas, and can circulate the liquid in the liquid circulation path B2. Moreover, although the pressure feeding means 116 is provided in the pipe f, the arrangement position is not limited to the pipe f, and may be arranged in the pipe e. The liquid circulation path B <b> 2 is connected to a pipe g having an external port 124 through which liquid can be led out to and from the ozone liquid generator 200. The pipe g is provided with a third on-off valve V3, whereby the amount of liquid flowing through the pipe g can be controlled.
　このため、外部口１２４を通じてオゾン液生成器２００の外部からオゾン液の生成に必要な水などの液体を給水することが可能であり、外部口１２４は、給水口としての役割を担う。また、外部口１２４は、オゾン液生成器２００の外部へ外部口１２４を通じてオゾン液を導出させることも可能である。このため、外部口１２４をオゾン液の導出口として使用する場合、オゾン液生成器２００の外部にオゾン液を導出することが可能なため、気液分離器１０３に液体導出口１１０を設けなくてもよい。例えば、気液分離器１０３には、導入口１０９と気体循環口１１１と液体循環口１１２とだけを設けた構成にしてもよい。 Therefore, it is possible to supply a liquid such as water necessary for generating the ozone liquid from the outside of the ozone liquid generator 200 through the external port 124, and the external port 124 serves as a water supply port. Further, the external port 124 can lead out the ozone liquid through the external port 124 to the outside of the ozone liquid generator 200. For this reason, when the external port 124 is used as the ozone liquid outlet, the ozone liquid can be led out of the ozone liquid generator 200. Therefore, the liquid outlet 110 is not provided in the gas-liquid separator 103. Also good. For example, the gas-liquid separator 103 may be provided with only the introduction port 109, the gas circulation port 111, and the liquid circulation port 112.
　＜動作説明＞
　次に、本実施形態に係るオゾン液生成器２００の動作について、図２から図７Ｂ及び図９を用いて説明する。ここで、開閉弁の開状態は、流体が開閉弁を流動可能な状態を意味し、閉状態は、流体が開閉弁により遮断され、流体の流動が停止された状態を意味するものとして説明する。 <Description of operation>
Next, operation | movement of the ozone liquid generator 200 which concerns on this embodiment is demonstrated using FIGS. 2-7B and FIG. Here, the open state of the on-off valve means that the fluid can flow through the on-off valve, and the closed state means that the fluid is blocked by the on-off valve and the fluid flow is stopped. .
　オゾン液生成器２００は、オゾン液生成器２００への給水時に、気液分離器１０３または液体循環経路Ｂ２に水などの液体を給水し、オゾン液の生成時に、オゾン液生成器２００により高濃度のオゾン液を生成し、オゾン液の導出時に、生成した高濃度のオゾン液を導出する。 The ozone liquid generator 200 supplies a liquid such as water to the gas-liquid separator 103 or the liquid circulation path B2 when water is supplied to the ozone liquid generator 200. When the ozone liquid is generated, the ozone liquid generator 200 generates a high concentration. The ozone liquid is generated, and the generated high-concentration ozone liquid is derived when the ozone liquid is derived.
　オゾン液生成器２００への給水時は、第１の開閉弁Ｖ１を閉状態にし、第２の開閉弁Ｖ２を開状態にし、第３の開閉弁Ｖ３を開状態にして、外部口１２４からオゾン液生成器２００に水などの液体を導入させ、圧送手段１１６により、液体を気液分離器１０３に導入する。 When water is supplied to the ozone liquid generator 200, the first on-off valve V1 is closed, the second on-off valve V2 is opened, the third on-off valve V3 is opened, and ozone is supplied from the external port 124. A liquid such as water is introduced into the liquid generator 200, and the liquid is introduced into the gas-liquid separator 103 by the pressure feeding means 116.
　導入された水などの液体は、気液分離器１０３に貯液されるとともに、液体循環経路Ｂ２に液体が循環する状態となる。液体の給水は、適切な液体量が気液分離器１０３または液体循環経路Ｂ２に貯液されるまで継続される。ここで、気液分離器１０３に貯液される液体の量は、少なくとも気液分離器１０３の液体循環口１１２を液体で塞ぐ必要があるため、少なくとも液体循環口１１２が設けられた高さを超える水位が必要となる。 The liquid such as introduced water is stored in the gas-liquid separator 103 and the liquid circulates in the liquid circulation path B2. The liquid supply is continued until an appropriate amount of liquid is stored in the gas-liquid separator 103 or the liquid circulation path B2. Here, the amount of liquid stored in the gas-liquid separator 103 needs to be at least the height at which the liquid circulation port 112 is provided because at least the liquid circulation port 112 of the gas-liquid separator 103 needs to be blocked with liquid. A higher water level is required.
　なお、第２の開閉弁Ｖ２を開状態にすると説明したが、閉状態にして気液分離器１０３に液体を貯液させても構わない。また、オゾンガス発生器１０１は、動作をさせてもよいし、停止させてもよい。 In addition, although it demonstrated that the 2nd on-off valve V2 was made into an open state, you may make it close and make the gas-liquid separator 103 store a liquid. Further, the ozone gas generator 101 may be operated or stopped.
　次に、オゾン液生成器２００による高濃度オゾン液の生成時の動作について説明する。オゾン液生成器２００による高濃度オゾン液の生成時には、第１の開閉弁Ｖ１を閉状態にし、第２の開閉弁Ｖ２を開状態にし、第３の開閉弁Ｖ３を閉状態にし、オゾンガス発生器１０１を動作させ、圧送手段１１６により、気液分離器１０３または液体循環経路Ｂ２の液体を循環させる。液体循環経路Ｂ２を循環し、気液混合器１０２の導入口１０６から導入された液体は、もう一方の導入口１０７から導入されたオゾンガスと混合され、オゾン液が生成される。ここで、導入口１０７から導入されるオゾンガスは、オゾンガス発生器１０１により生成されたものである。生成したオゾン液は、その後、配管ｃを介して、気液分離器１０３に導入されて貯液される。ここで、オゾン液には、液体にオゾンガスが溶け込んだオゾン溶液や液体にオゾンガスが気泡として含有されるオゾン含有液が含まれているため、気液分離器１０３の下層にオゾン溶液が貯液され、上層にオゾンガスや空気などを含む気体が貯蔵される。このため、気液分離器１０３においては、オゾンガスや空気などを含む気体とオゾン溶液を含む液体とに気液分離することが可能となる。 Next, the operation at the time of generating a high concentration ozone liquid by the ozone liquid generator 200 will be described. When the ozone liquid generator 200 generates high-concentration ozone liquid, the first on-off valve V1 is closed, the second on-off valve V2 is opened, the third on-off valve V3 is closed, and an ozone gas generator 101 is operated, and the liquid in the gas-liquid separator 103 or the liquid circulation path B2 is circulated by the pressure feeding means 116. The liquid circulating through the liquid circulation path B2 and introduced from the inlet 106 of the gas-liquid mixer 102 is mixed with the ozone gas introduced from the other inlet 107 to generate an ozone liquid. Here, the ozone gas introduced from the inlet 107 is generated by the ozone gas generator 101. The generated ozone liquid is then introduced into the gas-liquid separator 103 via the pipe c and stored. Here, since the ozone liquid contains an ozone solution in which ozone gas is dissolved in the liquid and an ozone-containing liquid in which the ozone gas is contained in the liquid as bubbles, the ozone solution is stored in the lower layer of the gas-liquid separator 103. A gas containing ozone gas or air is stored in the upper layer. For this reason, in the gas-liquid separator 103, it becomes possible to perform gas-liquid separation into a gas containing ozone gas or air and a liquid containing an ozone solution.
　分離されたオゾンガスや空気を含む気体は、配管ａを介して、オゾンガス発生器１０１に導入され、オゾンガス発生器１０１において、オゾンガスを含有する気体を原料にオゾンガスが発生させられる。このため、空気や酸素を原料に発生した場合に比べ、より高濃度のオゾンガスの生成が可能となる。 The separated gas containing ozone gas and air is introduced into the ozone gas generator 101 via the pipe a, and the ozone gas generator 101 generates ozone gas using the gas containing the ozone gas as a raw material. For this reason, compared with the case where air or oxygen is generated in the raw material, it is possible to generate ozone gas having a higher concentration.
　また、気体循環経路Ａ内の気体は、気液分離器１０３に貯液された液体と気液混合器１０２の液体とにより閉じ込められたいわゆる密封状態になっているため、水圧の影響を受けて圧縮された加圧状態となる。このため、オゾンガス発生器１０１または気液混合器１０２に高密度の気体を導入することが可能となるため、オゾンガス発生器１０１により高密度の気体に基づく、より高濃度のオゾンガスが発生させられ、気液混合器１０２により高密度のオゾンガスに基づく、効率的な気液混合効果が得られることになり、飛躍的に高い濃度のオゾン液を生成することが可能となる。 Further, since the gas in the gas circulation path A is in a so-called sealed state confined by the liquid stored in the gas-liquid separator 103 and the liquid in the gas-liquid mixer 102, it is affected by the water pressure. The compressed pressure state is obtained. For this reason, since it becomes possible to introduce a high-density gas into the ozone gas generator 101 or the gas-liquid mixer 102, a higher-concentration ozone gas based on the high-density gas is generated by the ozone gas generator 101, An efficient gas-liquid mixing effect based on high-density ozone gas can be obtained by the gas-liquid mixer 102, and it becomes possible to generate ozone liquid having a drastically high concentration.
　ここで、密封状態には、物理的に密封された空間だけではなく、気体が液体により閉じ込められた空間も含まれる意味として使用する。例えば、オゾン液生成器２００の気体循環経路Ａに気体を封止することができれば、常時、液体導出口１１０または液体循環口１１２から液体が導出されていても密封状態として表現する。 Here, the sealed state is used to mean not only a physically sealed space but also a space in which a gas is confined by a liquid. For example, if a gas can be sealed in the gas circulation path A of the ozone liquid generator 200, the liquid is always expressed as a sealed state even if the liquid is led out from the liquid outlet 110 or the liquid circulation port 112.
　その後、生成されたオゾンガスは、再び気液混合器１０２に導入され、気体循環経路Ａにて再び循環することになる。すなわち、生成されたオゾンガスは、気液混合器１０２、配管ｃ、気液分離器１０３、配管ａ、オゾンガス発生器１０１、配管ｂ、気液混合器１０２、配管ｃ、気液分離器１０３、・・・の順で繰り返し循環することになる。この結果、オゾンガス発生器１０１は、水に溶けきれず、気液分離されたオゾンガスを含有する気体をもとに、これを循環させてオゾン液を生成することになるため、より高濃度のオゾン液が生成されることとなる。 Thereafter, the generated ozone gas is again introduced into the gas-liquid mixer 102 and is circulated again in the gas circulation path A. That is, the generated ozone gas is gas-liquid mixer 102, pipe c, gas-liquid separator 103, pipe a, ozone gas generator 101, pipe b, gas-liquid mixer 102, pipe c, gas-liquid separator 103,. It will cycle repeatedly in the order. As a result, the ozone gas generator 101 does not dissolve in water and circulates it based on the gas containing the gas-liquid separated ozone gas to generate ozone liquid. A liquid will be produced.
　一方、気液分離器１０３により気液分離されたオゾン液は、配管ｅを介して気液混合器１０２に導入され、液体循環経路Ｂ２にて再び循環することになる。すなわち、気液分離されたオゾン液は、気液分離器１０３、配管ｅ、配管ｆ、気液混合器１０２、配管ｃ、気液分離器１０３、配管ｅ、配管ｆ、気液混合器１０２、・・・の順で繰り返し循環することになる。この結果、気液分離器１０３または液体循環経路Ｂ２を循環するオゾン液は、気液混合器１０２に繰り返し循環されることになるため、混合効率が向上し、より高濃度のオゾン液が生成されることとなる。 On the other hand, the ozone liquid separated by the gas-liquid separator 103 is introduced into the gas-liquid mixer 102 via the pipe e and circulates again in the liquid circulation path B2. That is, the gas-liquid separated ozone liquid is gas-liquid separator 103, pipe e, pipe f, gas-liquid mixer 102, pipe c, gas-liquid separator 103, pipe e, pipe f, gas-liquid mixer 102, It will circulate repeatedly in this order. As a result, the ozone liquid circulating in the gas-liquid separator 103 or the liquid circulation path B2 is repeatedly circulated to the gas-liquid mixer 102, so that the mixing efficiency is improved and a higher concentration ozone liquid is generated. The Rukoto.
　次に、オゾン液生成器２００によるオゾン液の導出時について、気液分離器１０３からオゾン液を導出させる場合と、液体循環経路Ｂ２と接続された外部口１２４から導出させる場合とについて説明する。 Next, when the ozone liquid is derived by the ozone liquid generator 200, the case where the ozone liquid is derived from the gas-liquid separator 103 and the case where the ozone liquid is derived from the external port 124 connected to the liquid circulation path B2 will be described.
　気液分離器１０３の液体導出口１１０からオゾン液を導出するオゾン液の導出時には、第１の開閉弁Ｖ１を開状態にし、第２の開閉弁Ｖ２を閉状態にし、第３の開閉弁Ｖ３を閉状態にする。なお、オゾンガス発生器１０１は動作をさせてもよいし、停止をさせてもよい。開閉弁を切り替えると、気液分離器１０３に貯液された高濃度のオゾン液が液体導出口１１０から導出される。 When deriving the ozone liquid from the liquid outlet 110 of the gas-liquid separator 103, the first on-off valve V1 is opened, the second on-off valve V2 is closed, and the third on-off valve V3 is discharged. Is closed. The ozone gas generator 101 may be operated or stopped. When the on-off valve is switched, high-concentration ozone liquid stored in the gas-liquid separator 103 is led out from the liquid outlet 110.
　外部口１２４からオゾン液を導出するオゾン液の導出時には、第１の開閉弁Ｖ１を閉状態にし、第２の開閉弁Ｖ２を開状態にし、第３の開閉弁Ｖ３を開状態にする。なお、オゾンガス発生器１０１は動作をさせてもよいし、停止をさせてもよい。開閉弁を切り替えると、気液分離器１０３に貯液された高濃度のオゾン液が配管ｅを介して外部口１２４から導出される。 When deriving the ozone liquid from the external port 124, the first on-off valve V1 is closed, the second on-off valve V2 is opened, and the third on-off valve V3 is opened. The ozone gas generator 101 may be operated or stopped. When the on-off valve is switched, high-concentration ozone liquid stored in the gas-liquid separator 103 is led out from the external port 124 via the pipe e.
　なお、オゾン液の導出を外部口１２４からのみ導出させる場合は、気液分離器１０３に液体導出口１１０を設ける必要がないため、気液分離器１０３に液体導出口１１０を設けずに動作させても構わない。例えば、気液分離器１０３には、導入口１０９と気体循環口１１１と液体循環口１１２とだけを設けた構成にしてもよい。 In the case where the ozone liquid is led out only from the external port 124, it is not necessary to provide the liquid lead-out port 110 in the gas-liquid separator 103. Therefore, the gas-liquid separator 103 is operated without providing the liquid lead-out port 110. It doesn't matter. For example, the gas-liquid separator 103 may be provided with only the introduction port 109, the gas circulation port 111, and the liquid circulation port 112.
　また、オゾン液の生成時とオゾン液の導出時との切り替えは、開閉弁を手動において切り替えてもよく、また、制御手段を設け、あらかじめプログラムされたタイミングやタイマーやオゾン液の濃度を検出するセンサなどを用いて制御してもよい。 In addition, switching between the time of ozone liquid generation and the time of ozone liquid derivation may be performed manually by switching the on-off valve, and a control means is provided to detect a preprogrammed timing, timer or ozone liquid concentration. You may control using a sensor etc.
