Description

【0001】
【発明の属する技術分野】
本発明はオゾン気泡を含むオゾン水を生成する装置に関するものである。更に詳しくは、本発明の装置は、食品その他を製造する加工工場、公共施設、飲食店舗、トイレ、浴室などの床、壁、器具、備品などの洗浄、除菌、脱臭または排水溝などの水場に発生する虫害の予防を行う装置に関するものである。
【0002】
【従来の技術】
一般に、大気を原料とするオゾン水の生成あるいはオゾン気泡混合水の生成には、オゾンガスと水とを混合するためのエジェクターやミキサーなどの器具を使用している。すなわち、エジェクター部分に水を導入し、水が通過する勢いによってエジェクター部分の途中に設けたオリフィスと管壁の間が真空状態になり、管上部に開いた穴からオゾンガスを吸入する。得られる水とオゾンガスを次の工程のミキサーに送り、水とオゾンガスを混合する。このときオゾンガスはミキサーによって細かい気泡状になり、水中に混合してオゾン気泡混合水を生成する。
【0003】
しかし、エジェクターとミキサーを使用した場合、その後、一旦オゾン気泡混合水中の気泡を減少させオゾン水とするために、一時滞留させる貯蔵タンク(反応槽)が必要である。例えば、装置内に毎分10リットルのオゾン気泡混合水を通過させ、最低3秒以上の滞留時間をとると、貯蔵タンク(反応槽)としては約0.5リットル以上の大きさのものが必要である。
しかし、本発明の装置は、小型・軽量で、装置の取扱いおよび運搬が容易であり、しかも片手で操作できるものである。本装置は、オゾン気泡およびオゾンを溶解状態で含有するオゾン水の混合物を同時に生成させることができる。
【0004】
携帯可能な小型の装置では、前記のような大きさの反応槽を内蔵することは困難である。また、エジェクターとミキサーのみを使する従来の生成方法では、貯蔵タンクを小さくし、あるいは除外することも考えられる。その場合には、オゾンが溶存する水を生成することは不可能であり、単にオゾン気泡が分散した水を生成できるのみである。また、オゾンが溶存するオゾン水の生成を促進するためにオゾン発生濃度を高くする場合には、高濃度のオゾンガスが気泡として装置外部に排出されて周辺の環境を劣化させる懸念がある。
【0005】
【発明が解決しようとする課題】
本発明は、従来小型化および軽量化できなかったエジェクター、ミキサーおよび反応槽からなる方式の装置を改良たものである。すなわち、エジェクターおよびミキサーの組み合わせの代わりに、2つオリフィスを持ち、エジェクター機能と即時に気泡の生成を行う機能とを一体化した気泡生成インジェクターノズルを使用し、さらに生成するオゾン気泡と水との反応時間を可能な限り長くするために邪魔板を内蔵した滞留配管および反応槽を設けることによって、オゾン気泡と水との反応タンクを小型化することを可能にし、かつ、片手で操作できる携帯可能なオゾン気泡を含むオゾン水を生成する装置を創案した。
【0006】
【課題を解決するための手段】
本発明の装置は、前記のような課題を解決するために鋭意検討を行った結果開発されたものである。すなわち、片手で操作でき、かつ容易に持ち運びできるように小型軽量化を図り、さらにオゾン発生能力を適正かつ安全に制御し、オゾン気泡の生成とオゾン水の生成とを同時に行うことができる装置を提供するものである。また、この装置の使用目的に合ったオゾン洗浄処理を行うために必要な能力を満たすために、オゾン気泡の生成とオゾン気泡の混合の両機能を一体化した気泡生成インジェクターノズルを使用したことを特徴とするものである。
【0007】
すなわち、本発明は、電磁弁を有する給水制御部、オゾンガス発生部、オゾン気泡を生成し、オゾン気泡と水とを混合するオゾン気泡-水混合部、およびオゾン水生成反応槽からなる、オゾン気泡を含むオゾン水の生成装置に関するものである。
【0008】
また、前記オゾンガス発生部の空気吸込み側の配管に逆止弁および排オゾン分解触媒からなる排ガス処理部を設け、装置を停止したときに大気に残余のオゾンガスが流出することを防止することができる装置である。
【0009】
さらに、前記給水制御部、オゾン発生部、オゾン気泡-水混合部、オゾン水生成反応槽、及び排ガス処理部を一体的に単一の筐体に収納したことを特徴とするものである。
【0010】
また、前記オゾン気泡-水混合部とオゾン水生成反応槽との中間に、オゾン気泡−水混合物を所定時間維持するための滞留配管を付加することができる。
【0011】
【発明の実施の形態】
以下に本発明の実施の形態を詳細に説明する。
本発明の小型軽量のオゾン気泡を含むオゾン水の生成装置の全体構成を図1に模式的に示す。
【0012】
まず、通常は上水道水を供給する給水ホース(図示せず)を給水制御部の給水口1に接続し、100V/AC電源を電源スイッチ2に接続する。次に、電源スイッチ2を操作し、制御基盤2bを経て給水制御用電磁弁3を開く。電磁弁3から混合部のインジェクターノズル7へ水が送られる。そこで水は、インジェクターノズル7のオリフィス7a(図2)によって激しい水流となり、オゾンガスの吸引口7bに負圧Vが発生する。
一方、オゾンガス発生部に設けたオゾン発生器4のスイッチ5を投入すると、オゾン発生確認ランプ2aが点灯し、オゾン発生器4が始動してオゾンガスが発生される。オゾン発生器4は2基示してあるが、制御基盤2bによって、1基のみを作動させる弱運転と2基を同時に作動させる強運転とに切り換えることも可能である。
【0013】
生成したオゾンガスは逆止弁6を経てインジェクターノズル7の吸引口7bへ吸入され、そこでオゾンガスと霧状に微細化された水とが混合されつつオゾンも微細な気泡になる。インジェクターノズル7で混合された霧状の微細な水とオゾンの微細な気泡は滞留配管8内で滞留して一部のオゾンが水の中に溶解し、さらにオゾン水生成反応槽9へ送られて反応槽9内に貯留されて充分に混合され、オゾンを溶解した状態で含有するオゾン水と未溶解のオゾン気泡からなる混合水になり、装置外に吐出することができる。このようなインジェクターノズルとしては、スプレーイングシステムスジャパン(株)製の商品名「バブリング・ジェット・ノズルYBJT−PVC10」などを例示することができる。
【0014】
前記滞留配管8にオゾン気泡混合水が入ると、滞留配管8の途中に設置してある邪魔板8aの作用によって混合水が激しく攪拌された状態で圧損がかかり貯留状態になる。なお、オゾン気泡混合水とは別に一部分が第一次オゾン水生成反応を行う。滞留配管8の寸法は、例えば、内径13mm以上、全長は150mm以上とし、邪魔板8aのオリフィスの径は管8の内径の1/2程度であり、邪魔板8aの設置位置は管8の全長の2/3よりも後方が好ましい。滞留配管8の構造を図3(a)および図3(b)に例示する。
【0015】
オゾン気泡−水混合物は滞留配管8を通過した後、最終処理としてオゾン水生成反応槽9に入る。オゾン水とオゾン気泡の混合水は、反応槽9内の邪魔板9aによって作られた複雑な通路を、オゾン水生成反応に必要な約3秒以上の時間をかけて通過し、オゾンがより高濃度に溶解したオゾン水と残余のオゾン気泡との混合物となり、装置の外部に吐出される。反応槽9の内部構造の一例を図4に示す。
【0016】
上記の装置を通過し、装置外部に吐出されたオゾン気泡を含むオゾン水の水部分のオゾン濃度は、本発明の目的である除菌、脱臭、洗浄、虫害発生の予防などに適する濃度が必要である。また、同時に装置から吐出されるオゾン気泡を含むオゾン水から発生するオゾンガスが使用領域周辺の環境の悪化を誘発しない程度でなければならない。
【0017】
そのためにオゾン水濃度を0.1ppm〜0.5ppmにすることが好ましい。また、吐出される混合水のオゾン気泡中のオゾン濃度は1ppm〜3ppm程度が好ましい。このオゾン水及びオゾン気泡のオゾン濃度の範囲内になるように、装置に付属する濃度調整機構によって適宜に調整することができる。例えば、図示のようにオゾン発生器4を2基使用して、2基を同時に作動させる「強」の相と1基のみを作動させる「弱」の相に使い分ける方法や、給水速度を増減することによって適宜に調節することが可能である。
【0018】
なお、装置の使用後に停止するとき、装置系内に残存するオゾンガスが大気中に放出されることを防止するために、前記オゾン発生器4の空気吸込み側の配管に逆止弁10および排オゾン分解触媒11からなる排ガス処理部を設けることができる。その場合、通常運転における空気の取入れは、分解触媒11および逆止弁10を経由して行えばよく、または他所に空気取入口を設けてもよい。
【0019】
図5および図6に、本発明の装置を筐体に収納した例について、装置を長手方向に半裁した両側の縦断側面を示す。
筐体12a、12bを形成する材質は、加工が容易で低廉な材料であれば、合成樹脂、軽金属など特に制限はない。本発明の装置の小型・軽量である特徴および製造コストなどを考慮すると、PVC(ポリ塩化ビニル)、ABS(アクリロニトリル-ブタジエン-スチレン)、ポリプロピレンなどの合成樹脂が好適である。
【0020】
図5および図6に示すように、筐体は大きく分けて電気制御部分12bとオゾン気泡-水混合生成部12aとに分離することができ、漏電や衝撃による故障や事故などの発生を防止している。
すなわち、図5に示す筐体12a側には、電磁弁3を有する給水制御部A、インジェクターノズル7を有するオゾン気泡−水混合部C、滞留配管8および反応往相槽9を有する反応槽部Dおよびおよび混合水吐出部Eを設ける。
【0021】
なお、第6図に示す反対側の筐体12bには、電気制御部や、端子台、フューズ、オゾン発生器4などのオゾンガス発生部Bを設け、それらが水に濡れないように装置内部に別室を設けるか、あるいは防水加工を施し、全体を前記筐体12aの反対側に取り付ける。
なお、オゾン発生器4の電源は多少の発熱を伴なうため、密閉状態ではなく、オゾン発生器の電源や、端子台、フューズなどの収納別室と装置筐体12bの外壁の適宜の個所に空気取入れ孔13を設けることが望ましい。
【0022】
【発明の効果】
本発明は、以上説明したような構造を有するので小型軽量で操作が容易であるとともに、オゾン気泡とオゾン水との混合物を効率よく生成することができ、しかも水にはオゾンが溶解している。
したがって、諸設備や器具類の洗浄、消毒、殺菌、脱臭あるいは虫害発生の予防などを効率的に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for generating ozone water containing ozone bubbles. More specifically, the apparatus of the present invention is used for processing plants, public facilities, restaurants, toilets, bathrooms and other floors, walls, appliances, fixtures, etc. for washing, sanitizing, deodorizing or draining water. The present invention relates to a device for preventing insect damage occurring on the ground.
[0002]
[Prior art]
Generally, instruments such as an ejector or a mixer for mixing ozone gas and water are used to generate ozone water using ozone as a raw material or ozone bubble mixed water. That is, water is introduced into the ejector part, and the space between the orifice provided in the middle of the ejector part and the tube wall is evacuated by the momentum of passing water, and ozone gas is sucked from a hole opened in the upper part of the tube. The obtained water and ozone gas are sent to the mixer in the next step to mix water and ozone gas. At this time, the ozone gas is formed into fine bubbles by a mixer and mixed in water to generate ozone bubble mixed water.
[0003]
However, when an ejector and a mixer are used, a storage tank (reaction tank) that temporarily retains is necessary in order to reduce the bubbles in the ozone bubble mixed water once to obtain ozone water. For example, if ozone bubble mixed water of 10 liters per minute is passed through the apparatus and a residence time of at least 3 seconds is taken, a storage tank (reaction tank) having a size of about 0.5 liters or more is required. It is.
However, the device of the present invention is small and light, can be easily handled and transported, and can be operated with one hand. This apparatus can simultaneously generate a mixture of ozone water containing ozone bubbles and ozone in a dissolved state.
[0004]
In a small portable device, it is difficult to incorporate a reaction tank having the above size. Moreover, in the conventional production method using only an ejector and a mixer, it is conceivable to reduce or eliminate the storage tank. In that case, it is impossible to generate water in which ozone is dissolved, and it is only possible to generate water in which ozone bubbles are dispersed. Further, when the ozone generation concentration is increased in order to promote the generation of ozone water in which ozone is dissolved, there is a concern that high-concentration ozone gas is discharged as bubbles to the outside of the apparatus and deteriorates the surrounding environment.
[0005]
[Problems to be solved by the invention]
The present invention is an improvement of an apparatus of a system comprising an ejector, a mixer and a reaction tank that could not be reduced in size and weight. That is, instead of a combination of an ejector and a mixer, a bubble generating injector nozzle that has two orifices and integrates the ejector function and the function of generating bubbles immediately is used. In order to make the reaction time as long as possible, it is possible to miniaturize the reaction tank of ozone bubbles and water by providing a staying pipe with a baffle plate and a reaction tank, and it can be operated with one hand A device to generate ozone water containing various ozone bubbles was devised.
[0006]
[Means for Solving the Problems]
The apparatus of the present invention has been developed as a result of intensive studies to solve the above-described problems. In other words, a device that can be operated with one hand and is reduced in size and weight so that it can be easily carried, and the ozone generation capability is appropriately and safely controlled, so that ozone bubbles can be generated and ozone water can be generated simultaneously. It is to provide. In addition, in order to meet the capacity required to perform ozone cleaning treatment that suits the purpose of use of this device, it was confirmed that a bubble generation injector nozzle that integrated both ozone bubble generation and ozone bubble mixing functions was used. It is a feature.
[0007]
That is, the present invention is an ozone bubble comprising a water supply control unit having an electromagnetic valve, an ozone gas generation unit, an ozone bubble-water mixing unit that generates ozone bubbles and mixes the ozone bubbles and water, and an ozone water generation reaction tank. It is related with the production | generation apparatus of ozone water containing.
[0008]
In addition, an exhaust gas treatment unit including a check valve and an exhaust ozone decomposition catalyst is provided in the air suction side pipe of the ozone gas generation unit, so that the remaining ozone gas can be prevented from flowing out to the atmosphere when the apparatus is stopped. Device.
[0009]
Furthermore, the water supply control unit, the ozone generation unit, the ozone bubble-water mixing unit, the ozone water generation reaction tank, and the exhaust gas treatment unit are integrally housed in a single casing.
[0010]
In addition, a retention pipe for maintaining the ozone bubble-water mixture for a predetermined time can be added between the ozone bubble-water mixing unit and the ozone water generation reaction tank.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 schematically shows the overall configuration of a device for generating ozone water containing small and light ozone bubbles of the present invention.
[0012]
First, a water supply hose (not shown) that normally supplies tap water is connected to the water supply port 1 of the water supply control unit, and a 100 V / AC power supply is connected to the power switch 2. Next, the power switch 2 is operated to open the water supply control solenoid valve 3 through the control board 2b. Water is sent from the electromagnetic valve 3 to the injector nozzle 7 in the mixing section. Accordingly, the water becomes a violent water flow through the orifice 7a (FIG. 2) of the injector nozzle 7, and a negative pressure V is generated at the ozone gas suction port 7b.
On the other hand, when the switch 5 of the ozone generator 4 provided in the ozone gas generator is turned on, the ozone generation confirmation lamp 2a is turned on, and the ozone generator 4 is started to generate ozone gas. Although two ozone generators 4 are shown, the control base 2b can be switched between a weak operation in which only one unit is operated and a strong operation in which two units are simultaneously operated.
[0013]
The generated ozone gas passes through the check valve 6 and is sucked into the suction port 7b of the injector nozzle 7, where the ozone gas becomes fine bubbles while the ozone gas and water atomized in a mist form are mixed. The mist-like fine water and fine ozone bubbles mixed in the injector nozzle 7 stay in the stay pipe 8 and a part of ozone is dissolved in the water, and further sent to the ozone water generation reaction tank 9. Thus, it is stored in the reaction tank 9 and mixed sufficiently, and becomes a mixed water composed of ozone water contained in a dissolved ozone state and undissolved ozone bubbles, and can be discharged out of the apparatus. An example of such an injector nozzle is a product name “Bubbling Jet Nozzle YBJT-PVC10” manufactured by Spraying Systems Japan Co., Ltd.
[0014]
When the ozone bubble mixed water enters the staying pipe 8, the mixed water is vigorously stirred by the action of the baffle plate 8 a installed in the middle of the staying pipe 8, resulting in a storage state due to pressure loss. In addition, a part of the ozone bubble mixed water performs a primary ozone water generation reaction. The dimensions of the staying pipe 8 are, for example, an inner diameter of 13 mm or more and an overall length of 150 mm or more, the diameter of the orifice of the baffle plate 8 a is about ½ of the inner diameter of the pipe 8, and the installation position of the baffle plate 8 a is the entire length of the pipe 8. The rear is more preferable than 2/3. The structure of the staying pipe 8 is illustrated in FIGS. 3 (a) and 3 (b).
[0015]
The ozone bubble-water mixture passes through the residence pipe 8 and then enters the ozone water generation reaction tank 9 as a final treatment. The mixed water of ozone water and ozone bubbles passes through the complicated passage formed by the baffle plate 9a in the reaction tank 9 over about 3 seconds required for the ozone water generating reaction, and the ozone is higher. It becomes a mixture of ozone water dissolved in the concentration and the remaining ozone bubbles, and is discharged outside the apparatus. An example of the internal structure of the reaction vessel 9 is shown in FIG.
[0016]
The ozone concentration in the water portion of the ozone water containing ozone bubbles that have passed through the device and discharged outside the device must be suitable for the purpose of the present invention, such as sterilization, deodorization, washing, and prevention of insect damage. It is. At the same time, the ozone gas generated from the ozone water containing ozone bubbles discharged from the apparatus must be such that the environment around the use area is not deteriorated.
[0017]
Therefore, the ozone water concentration is preferably 0.1 ppm to 0.5 ppm. Further, the ozone concentration in the ozone bubbles of the mixed water to be discharged is preferably about 1 ppm to 3 ppm. The concentration can be appropriately adjusted by a concentration adjusting mechanism attached to the apparatus so as to be within the ozone concentration range of the ozone water and the ozone bubbles. For example, as shown in the figure, two ozone generators 4 are used, and a method of selectively using a “strong” phase in which two units are operated simultaneously and a “weak” phase in which only one unit is operated, or a water supply speed is increased or decreased. It is possible to adjust appropriately.
[0018]
In order to prevent the ozone gas remaining in the apparatus system from being released into the atmosphere when the apparatus is stopped after use, a check valve 10 and exhaust ozone are connected to the air suction side piping of the ozone generator 4. An exhaust gas treatment unit comprising the cracking catalyst 11 can be provided. In that case, the intake of air in the normal operation may be performed via the cracking catalyst 11 and the check valve 10, or an air intake may be provided elsewhere.
[0019]
FIG. 5 and FIG. 6 show the longitudinal side surfaces on both sides of the example in which the apparatus of the present invention is housed in a casing, in which the apparatus is half cut in the longitudinal direction.
The material forming the casings 12a and 12b is not particularly limited as long as the material is easy to process and inexpensive. Considering the small size and light weight of the device of the present invention and the manufacturing cost, synthetic resins such as PVC (polyvinyl chloride), ABS (acrylonitrile-butadiene-styrene), and polypropylene are suitable.
[0020]
As shown in FIG. 5 and FIG. 6, the housing can be roughly divided into an electric control part 12b and an ozone bubble-water mixture generation part 12a to prevent the occurrence of breakdown or accident due to electric leakage or impact. ing.
That is, on the housing 12 a side shown in FIG. 5, a water supply control unit A having an electromagnetic valve 3, an ozone bubble-water mixing unit C having an injector nozzle 7, a residence pipe 8 and a reaction tank unit having a reaction forward phase tank 9. D and the mixed water discharge part E are provided.
[0021]
The opposite housing 12b shown in FIG. 6 is provided with an electrical control unit, an ozone gas generation unit B such as a terminal block, a fuse, and an ozone generator 4, so that they are not wetted with water. A separate chamber is provided or waterproofing is performed, and the whole is attached to the opposite side of the casing 12a.
Since the power source of the ozone generator 4 is somewhat heated, it is not hermetically sealed, and is not provided in an appropriate place on the ozone generator power source, a separate storage room such as a terminal block or a fuse, and the outer wall of the device housing 12b. It is desirable to provide an air intake hole 13.
[0022]
【The invention's effect】
Since the present invention has the structure as described above, it is small and light and easy to operate, and can efficiently generate a mixture of ozone bubbles and ozone water, and ozone is dissolved in water. .
Therefore, it is possible to efficiently perform cleaning, disinfection, sterilization, deodorization, or prevention of insect damage of various facilities and instruments.
