Description

本発明は、液体中に微細な気泡、あるいは粉体を混入して生成したマイクロバブル、マイクロ粒子を発生させるマイクロバブルおよび／またはマイクロ粒子を含む液体発生装置、およびマイクロバブルおよび／またはマイクロ粒子を含む液体、並びにマイクロバブルおよび／またはマイクロ粒子を含む液体の製造方法に関する。   The present invention relates to a microbubble generated by mixing fine bubbles or powder in a liquid, a microbubble and / or a microparticle that generates microparticles, and a microbubble and / or microparticle. The present invention relates to a liquid containing liquid and a method for producing a liquid containing microbubbles and / or microparticles.

一般に、微細な気泡を液体中に発生させるには、液体と気泡を発生させるための装置を用意して、上記液体に気泡を注入、あるいは液体を撹拌等によって直接気泡を当該液体中に発生させるマイクロバブルを発生装置が提案されている。
マイクロバブル発生装置として、例えば、液体を電気分解によってマイクロバブルを発生させるため、多孔質性を有する導電性材料を用いて液体を電気分解するための２電極で構成した特開２００７−３８１４９号が提案されている。
特開２００７−３８１４９号 Generally, in order to generate fine bubbles in a liquid, a device for generating the liquid and bubbles is prepared, and bubbles are injected into the liquid, or bubbles are directly generated in the liquid by stirring the liquid. Microbubble generating devices have been proposed.
As a microbubble generator, for example, Japanese Patent Application Laid-Open No. 2007-38149 is composed of two electrodes for electrolyzing a liquid using a porous conductive material in order to generate microbubbles by electrolyzing the liquid. Proposed.
JP 2007-38149 A

ところが、先行技術として上述の公報に示された構成では、導電性材料に多孔質性を有するチタン又は導電性セラミック等の比較的高価な材料を用いる必要があると共に、上記マイクロバブルを形成させる場合、そのマイクロバブルの粒径又はその分布のコントロールが出来ない、あるいは気体（ガス）として酸素、水素に限定される欠点があるので、マイクロバブル発生装置として、種々の要求に応えられるものではなく、必ずしも有効な構成とはいえない。   However, in the configuration disclosed in the above-mentioned publication as the prior art, it is necessary to use a relatively expensive material such as porous titanium or conductive ceramic as the conductive material and to form the microbubbles. , The particle size of the microbubbles or their distribution cannot be controlled, or because there is a drawback that the gas (gas) is limited to oxygen, hydrogen, as a microbubble generator, it does not meet various requirements, It is not necessarily an effective configuration.

本発明は、上記要求に対して、マイクロバブルあるいはマイクロ粒子の径あるいはその分布がコントロール出来、更に、液体中に気体のマイクロバブル、又は液体、固体およびその混合体の微細な粒径を有するマイクロ粒子を液体中に発生させることが出来る新規な構成のマイクロバブル、マイクロ粒子発生装置、及びマイクロバブル、マイクロ粒子を有する液体、並びにその製造方法を提供するものである。   The present invention can control the diameter of microbubbles or microparticles or the distribution thereof in response to the above requirements, and further, the microbubbles in the liquid or the microparticles having a fine particle diameter of a liquid, a solid and a mixture thereof. The present invention provides a microbubble having a novel configuration capable of generating particles in a liquid, a microparticle generator, a microbubble, a liquid having microparticles, and a method for producing the same.

先ず、本発明は、液体槽と、多数の貫通孔を有する多孔のノズルと、圧力槽と、超音波振動素子を有する振動源からなり、上記液体槽に所定の液体を貯蔵し、圧力槽に気体、液体、粉体、あるいはその混合体を注入し、ホーンを構成する多孔のノズルを通して液体中に圧入または噴射することによって、上記液体中に種々の超微細な気泡または液体、気体、固体、およびその混合体の微粒子体を発生させるマイクロバブルおよび／またはマイクロ粒子を含む液体発生装置、およびマイクロバブルおよび／またはマイクロ粒子を含む液体、並びにマイクロバブルおよび／またはマイクロ粒子を含む液体の製造方法を提供すものである。   First, the present invention comprises a liquid tank, a porous nozzle having a large number of through holes, a pressure tank, and a vibration source having an ultrasonic vibration element. The liquid tank stores a predetermined liquid, and the pressure tank By injecting or injecting gas, liquid, powder, or a mixture thereof into the liquid through a porous nozzle constituting a horn, various ultrafine bubbles or liquids, gas, solid, And a liquid generator including microbubbles and / or microparticles for generating fine particles of the mixture thereof, a liquid including microbubbles and / or microparticles, and a method for producing a liquid including microbubbles and / or microparticles It is to provide.

更に、本発明は、上記圧力槽に設けた振動源の超音波振動素子を上記多孔のノズルに密着させて多孔を有する多孔膜を振動させて、液体槽に向かって圧力槽から所定の気体、液体、粉体、およびその混合体等を、上記液体中にマイクロバブル、マイクロ粒子として発生させる構成を提案するものである。   Further, according to the present invention, an ultrasonic vibration element of a vibration source provided in the pressure tank is brought into close contact with the porous nozzle to vibrate a porous film having a porosity, and a predetermined gas is discharged from the pressure tank toward the liquid tank, The present invention proposes a configuration in which liquid, powder, a mixture thereof, and the like are generated as microbubbles and microparticles in the liquid.

また、本発明は、上記振動源に超音波振動素子を用いる、あるいは超音波振動素子としてチタン酸ジルコン酸鉛（ＰＺＴ）、チタン酸バリューム、フェライト等を用いることによって上記液体槽中に微細な粒径のマイクロバブル、マイクロ粒子を発生させる構成である。   Further, the present invention uses an ultrasonic vibration element as the vibration source, or uses fine particles in the liquid tank by using lead zirconate titanate (PZT), titanium titanate, ferrite, or the like as the ultrasonic vibration element. This is a configuration for generating microbubbles and microparticles having a diameter.

更に、本発明は、上記振動源の周波数及び電圧を調整し、上記多孔のノズルの孔形状、孔径を種々選択することによって上記液体槽中に発生させるマイクロバブル、マイクロ粒子の粒径を調整することが可能なマイクロバブル、マイクロ粒子発生装置を提案する。
また、本発明は、上記装置および構成により製作されたマイクロバブル、マイクロ粒子を含む機能性を有する液体、その液体の製造方法を提供するものである。 Furthermore, the present invention adjusts the frequency and voltage of the vibration source, and adjusts the microbubbles generated in the liquid tank and the particle size of the microparticles by variously selecting the hole shape and hole diameter of the porous nozzle. We propose a microbubble and microparticle generator.
The present invention also provides a microbubble produced by the above-described apparatus and configuration, a liquid having functionality containing microparticles, and a method for producing the liquid.

本発明に関わるマイクロバブルおよび／またはマイクロ粒子を含む液体発生装置は、上述の構成によって液体槽に貯蔵した液体中に、気体、液体、粉体、あるいはその混合体として例えば油脂等を適宜選択して、ノズルの孔径、密度に応じて所定の粒径、あるいはその分布を有する微細な粒体としてのマイクロバブルおよび／またはマイクロ粒子を発生させることができる。   The liquid generator including the microbubbles and / or microparticles according to the present invention appropriately selects, for example, fats and oils as gas, liquid, powder, or a mixture thereof in the liquid stored in the liquid tank with the above-described configuration. Thus, it is possible to generate microbubbles and / or microparticles as fine particles having a predetermined particle size or distribution according to the nozzle hole diameter and density.

この場合、上記多孔のノズルの素材として耐食性を有するものを選べば、多孔のノズルの寿命が長く、従って装置としての寿命も長く保つことが可能となる。
この際、更に、上記多孔のノズルの表面を、液体槽内の液体に応じて親水性、撥水性、あるいは撥油性処理を施すことによって気液の界面及び液界面に位置する多孔のノズルの液体切れ、気体切れの有効に微細な粒径のマイクロバブルおよび／またはマイクロ粒子を発生させることが出来る。 In this case, if a material having corrosion resistance is selected as the material of the porous nozzle, the life of the porous nozzle is long, and therefore the life of the device can be kept long.
At this time, the surface of the porous nozzle is further subjected to hydrophilic, water repellency, or oil repellency treatment according to the liquid in the liquid tank, so that the liquid of the porous nozzle located at the gas-liquid interface and the liquid interface is provided. It is possible to generate microbubbles and / or microparticles having a fine particle size that are effectively cut or out of gas.

また、上記振動源の電圧、周波数を選択することによって多孔のノズル振動モードが制御出来る、その結果マイクロバブルあるいはマイクロ粒子の直径を制御できるので、従来では得られなかったマイクロバブルおよび／またはマイクロ粒子の粒子径を発生源である多孔のノズルの表面で粒子径が制御可能となる。   In addition, by selecting the voltage and frequency of the vibration source, the porous nozzle vibration mode can be controlled. As a result, the diameter of microbubbles or microparticles can be controlled. The particle size can be controlled on the surface of the porous nozzle that is the source of the particle size.

Then, a predetermined gas, powder, or liquid is introduced to give pressure (P1), and a pressure tank 4 connected to the liquid tank 1 through the porous nozzle 2 and the pressure tank 4 A vibration source 3 provided with a piezoelectric vibration element on the side wall facing the porous nozzle 2 and a piezoelectric vibration element provided on the vibration source 3 are connected to generate a drive signal having a predetermined voltage and frequency. And at least a drive source 5.

次に、図１（Ａ）及び図１(Ｂ) について説明すると、マイクロバブルおよび／またはマイクロ粒子発生装置は、圧電振動素子等からなる駆動源５から圧力槽４の一方の壁からなる振動源３に対して所定の電圧と周波数を有する駆動信号を供給し、振動源３の圧電振動素子を所定の振幅と、所定の振動を発生させる。
上記液体槽１における前記多孔のノズル２の近傍は、中に貯蔵された液体の重量に伴う一定の圧力（Ｐ０）となっている。前記圧力（Ｐ０）と前記圧力槽４に加えられる圧力（Ｐ１）の関係は、Ｐ１＞Ｐ０の関係に設定しておく。 Next, FIG. 1 (A) and FIG. 1 (B) will be described. A microbubble and / or microparticle generator includes a vibration source consisting of one wall of a pressure vessel 4 from a driving source 5 consisting of a piezoelectric vibration element or the like. 3 is supplied with a drive signal having a predetermined voltage and frequency, and the piezoelectric vibration element of the vibration source 3 generates a predetermined amplitude and a predetermined vibration.
The vicinity of the porous nozzle 2 in the liquid tank 1 has a constant pressure (P0) associated with the weight of the liquid stored therein. The relationship between the pressure (P0) and the pressure (P1) applied to the pressure vessel 4 is set to a relationship of P1> P0.

先ず、実施例である図１について説明する。マイクロバブルおよび／またはマイクロ粒子発生装置は、液体槽１に投入された液体６と、多数の微細な貫通孔を設けた多孔のノズル２と、振動源３に設けた超音波振動素子と、一定の圧力（Ｐ１）がエアポンプ等によって加えられた圧力槽４と、所定の電圧によって上記多孔のノズル２に向かって振動を発生させる駆動源５で上記超音波振動素子を駆動させることにより、圧力槽４から多孔を有するノズル２を通して液体槽１内にマイクロバブルおよび／またはマイクロ粒子として多孔のノズル２の孔の大きさに対応した、極めて微細な気泡及び微粒子となって発生させることができる。   First, FIG. 1 as an embodiment will be described. The microbubble and / or microparticle generator includes a liquid 6 charged into the liquid tank 1, a porous nozzle 2 provided with a large number of fine through holes, an ultrasonic vibration element provided in the vibration source 3, and a constant By driving the ultrasonic vibration element with a pressure tank 4 to which the pressure (P1) is applied by an air pump or the like and a drive source 5 that generates vibration toward the porous nozzle 2 with a predetermined voltage, the pressure tank The microbubbles and / or microparticles corresponding to the size of the pores of the porous nozzle 2 can be generated as microbubbles and / or microparticles in the liquid tank 1 through the nozzle 2 having porosity from 4.

図１は（Ａ）、（Ｂ）で示すように、この場合、多孔のノズル２と振動源３とは、別体で上記振動源３を圧力槽４の端部に上記多孔のノズル２に対向した位置に配置してある。
従って、この例において、上記振動源３は、多孔のノズル２に向かって圧力槽４のホーンとしての機能を用いるべく振動源３に設けた圧電振動素子によって振動を与える構成である。 As shown in FIGS. 1A and 1B, in this case, the porous nozzle 2 and the vibration source 3 are separated from each other, and the vibration source 3 is provided at the end of the pressure tank 4. It is arranged at the opposite position.
Therefore, in this example, the vibration source 3 is configured to apply vibration to the porous nozzle 2 by a piezoelectric vibration element provided in the vibration source 3 so as to use the function as the horn of the pressure tank 4.

一方、図２に示した例において、本発明に関わるマイクロバブルおよび／またはマイクロ粒子発生装置は、内部に液体６を貯蔵する液体槽１と、前記液体槽１の下部近傍の側壁に設けられた多数の微細な貫通孔を有する多孔のノズル２と、所定の気体、粉体、又は液体が投入されて圧力（Ｐ１）が与えられるとともに、前記多孔のノズル２を介して前記液体槽１に連設された圧力槽４と、前記多孔のノズル２に密着させた振動源３と、前記振動源３に設けた圧電振動素子に接続され、所定の電圧と周波数を有する駆動信号を発生する駆動源５とから少なくとも構成されている。この図２の実施例は、圧力槽４の端部が図２の右端のようにストレート構造で事足り、圧力P1を加える部分が簡単な構造となる。   On the other hand, in the example shown in FIG. 2, the microbubble and / or microparticle generator according to the present invention is provided in the liquid tank 1 for storing the liquid 6 therein and the side wall near the lower part of the liquid tank 1. A porous nozzle 2 having a large number of fine through-holes and a predetermined gas, powder, or liquid are introduced to apply pressure (P1) and communicate with the liquid tank 1 through the porous nozzle 2. A pressure source 4 provided, a vibration source 3 closely attached to the porous nozzle 2, and a piezoelectric vibration element provided in the vibration source 3, and a drive source for generating a drive signal having a predetermined voltage and frequency 5 and at least. In the embodiment of FIG. 2, the end of the pressure vessel 4 is sufficient as a straight structure as shown in the right end of FIG. 2, and the portion to which the pressure P1 is applied becomes a simple structure.

例えば、圧力槽４に12パスカルの圧力をかけ、振動源にチタン酸ジルコン酸鉛（ＰＺＴ）を用い、６V の電圧印加で130kＨｚの振動を発生させ、多孔のノズルの孔径を2.0 μｍφにして、酸素ガスを液体層１に注入したところ、おおよそ数μｍφ、好ましくは５μｍφの酸素ガス微粒子が液中に注入出来た。   For example, a pressure of 12 Pascals is applied to the pressure tank 4, lead zirconate titanate (PZT) is used as a vibration source, a vibration of 130 kHz is generated by applying a voltage of 6 V, and the pore diameter of the porous nozzle is set to 2.0 μmφ. When oxygen gas was injected into the liquid layer 1, oxygen gas fine particles of approximately several μmφ, preferably 5 μmφ, could be injected into the liquid.

また、圧力槽４にサラダオイルを入れその中に200 ｎｍの粒径の銀の粉末を３重量パーセント混合して12パスカルの圧力をかけながら振動源３にチタン酸ジルコン酸鉛（ＰＺＴ）を用い、６ボルトの電圧で、130kＨｚの交流を印加させた場合、多孔ノズルの孔径を６μｍφにして銀の微粒子を混入させると、液体中には微細な銀粉末が上記サラダオイルによって覆われた状態の微粒子が得られる。   In addition, salad oil is put into the pressure vessel 4 and mixed with 3% by weight of silver powder having a particle size of 200 nm, and while using 12 Pascal pressure, lead zirconate titanate (PZT) is used as the vibration source 3. When an alternating current of 130 kHz is applied at a voltage of 6 volts, a fine silver powder is covered with the salad oil when the pore diameter of the porous nozzle is set to 6 μmφ and silver fine particles are mixed. Fine particles are obtained.

次に、振動源３に用いる圧電振動素子は、極めて振動効率が良いチタン酸ジルコン酸鉛（ＰＺＴ）、チタン酸バリューム、フェライトを使用すれば有効である。また、上記液体槽に貯蔵させる液体６は、水あるいは各種化学薬品、特に、薬剤でも良く、また、有機溶媒でも良い。上記液体槽１に貯蔵された液体は、圧力槽４に挿入するものを、それぞれ要求する機能を有した気体、液体、粉体、およびその混合体を選べば、新たな機能を有する液体として調合が可能となる。   Next, the piezoelectric vibration element used for the vibration source 3 is effective when lead zirconate titanate (PZT), titanium titanate, or ferrite having extremely good vibration efficiency is used. Further, the liquid 6 stored in the liquid tank may be water or various chemicals, particularly a chemical, or an organic solvent. The liquid stored in the liquid tank 1 is prepared as a liquid having a new function by selecting the gas, liquid, powder and mixture thereof having the functions required for the one to be inserted into the pressure tank 4. Is possible.

金属粒子を製作は、上記多孔のノズル２を挟んで液体槽１に還元液を、圧力槽４に金属錯塩溶液をそれぞれ投入して、圧力槽４より金属錯塩溶液の微粒子を噴射させ、酸化還元反応を行うことができる。   The metal particles are produced by putting the reducing liquid into the liquid tank 1 and the metal complex salt solution into the pressure tank 4 with the porous nozzle 2 sandwiched between them, and spraying the metal complex salt solution fine particles from the pressure tank 4 to perform oxidation reduction. The reaction can be performed.

また、上記多孔のノズル３を挟んで液体槽１に摂氏５０度〜９０度の液体を投入し圧力槽４に所定の樹脂を合成するモノマーと、開始剤、たとえば、メタクリル酸メチル（モノマー Ｍｅｔｈａｃｒｙｌａｔｅ−ＭＭＡ）、エチレングリコールジアメタアクリル（Ｅｔｈｙｌｅｎｅ Ｇｌｙｃｏ Ｄｉａｍｅｔｈａ Ａｃｒｙｌ−ＥＧＤＭＡ）、アゾビスイソスプチロニトリル（Ａｚｏｂｉｓ Ｉｓｏｂｕｔｙｒｏｎｉｔｒｉｌｅ−ＡＩＢＮ）、硬化剤、触媒の混合液を投入し、圧力槽４よりモノマー混合液を多孔のノズル３より微粒子を液体槽１に噴射させ、液体槽１の液中にモノマー粒子を一定時間漂わせ、モノマーをポリマー樹脂に合成して、その結果、ポリマーのマイクロ粒子を発生させることが出来る。   In addition, a monomer that synthesizes a predetermined resin into the pressure tank 4 by introducing a liquid at 50 to 90 degrees Celsius into the liquid tank 1 with the porous nozzle 3 interposed therebetween, and an initiator such as methyl methacrylate (monomer Methacrylate- MMA), ethylene glycol diamethacrylic acid (Ethylene Glyco Diametha Acryl-EGDMA), azobisisospythronitrile (Azobis Isobutyronitrile-AIBN), a curing agent, and a mixed solution of catalyst, and a monomer mixed solution from pressure vessel 4 is made porous. Fine particles are sprayed from the nozzle 3 into the liquid tank 1, the monomer particles are allowed to float in the liquid in the liquid tank 1 for a certain period of time, and the monomer is synthesized into a polymer resin. As a result, polymer microparticles can be generated. .

更に、上記多孔のノズル２を挟んで液体槽１に酸性水溶液、例えば塩酸の１規定溶液を満たし、圧力槽４に珪酸ソーダの５０％水溶液を投入し、多孔のノズル３を通じて圧力槽４より珪酸ソーダ溶液の微粒子を液体槽１の酸性溶液に噴射し、珪酸ソーダが中和され、二酸化珪素（SiO2）の微粒子に合成することができる。 Further, an acidic aqueous solution, for example, 1N solution of hydrochloric acid is filled in the liquid tank 1 with the porous nozzle 2 interposed therebetween, and a 50% aqueous solution of sodium silicate is introduced into the pressure tank 4. The fine particles of the soda solution are sprayed onto the acidic solution in the liquid tank 1, so that the sodium silicate is neutralized and synthesized into fine particles of silicon dioxide (SiO 2 ).

更に、振動源３に設けた超音波振動素子に与える駆動源５からの駆動信号の電圧あるいは周波数を変えることによって、マイクロバブルの粒径を変化させて所望のマイクロバブルおよび／またはマイクロ粒子を発生させることができる。上記多孔のノズル２の孔径を変えることによって、上述のような粒径あるいは分布を変化させることも可能となる。   Further, by changing the voltage or frequency of the drive signal from the drive source 5 applied to the ultrasonic vibration element provided in the vibration source 3, the microbubbles particle size is changed to generate desired microbubbles and / or microparticles. Can be made. By changing the hole diameter of the porous nozzle 2, the particle diameter or distribution as described above can be changed.

上記多孔のノズル２の材質を種々の材料を用いて選択すれば、耐食性が達成することが出来ると共に、特に、薬剤の調合、あるいは食品の製造に本発明を用いる場合、人体等に無害な材質を選択出来る。   If the material of the porous nozzle 2 is selected using various materials, corrosion resistance can be achieved. In particular, when the present invention is used for pharmaceutical preparation or food production, the material is harmless to the human body or the like. Can be selected.

更に、上記多孔のノズル２に表面処理、即ち、上記多孔のノズル２の表面に親水性、撥水性、親油性、あるいは撥油性処理を行うことによって、液体槽１に貯蔵する液体と、圧力槽４に挿入する材料を選択することが出来る。また、液体槽１に貯蔵する液体は、燃料とした場合、本発明によって、マイクロバブルを上記液体中に発生させると、その燃焼効率が向上させることが可能となり、例えば、輸送機器におけるエンジンに利用することが出来る。   Furthermore, the surface of the porous nozzle 2 is subjected to surface treatment, that is, the surface of the porous nozzle 2 is subjected to hydrophilicity, water repellency, oleophilicity, or oil repellency treatment. The material to be inserted into 4 can be selected. In addition, when the liquid stored in the liquid tank 1 is fuel, if microbubbles are generated in the liquid according to the present invention, the combustion efficiency can be improved. I can do it.

上記圧力槽４に水に対して溶解しにくい無機ガス、あるいは有機ガスを挿入することによって、液体中に気泡を保持することが可能となり、その結果、同液体を農業、園芸、林業関係の、殺菌、酸素供給、等各種の目的に対応した水が出来る。その気体の例として、酸素ガス、オゾン、窒素ガス、二酸化炭素ガス、あるいはメタンガス、ブタンガスを含む有機ガスを、たとえば、数μｍφ、好ましくは５μｍφ以下にする事により液中にいつまでも存在する所定の気泡混入液が得られる。   By inserting an inorganic gas or an organic gas that is difficult to dissolve in water into the pressure tank 4, it becomes possible to retain bubbles in the liquid. As a result, the liquid can be used for agriculture, horticulture, forestry, Water corresponding to various purposes such as sterilization and oxygen supply can be produced. Examples of the gas include oxygen gas, ozone, nitrogen gas, carbon dioxide gas, or organic gas containing methane gas and butane gas, for example, several μmφ, preferably 5 μmφ or less, for example, predetermined bubbles that exist in the liquid forever. A mixed liquid is obtained.
