Description

【0001】
【産業上の利用分野】本発明は諸種の技術分野において有用な製品或いは中間製品となる微小気泡含有液状物及び其の製造方法に関するものである。
【0002】
【従来の技術】液中に微小気泡を作る技術は従来から多くの提案がなされており、近年では特に水質改善、浴槽関連の分野に関心が集まっている。これらの方法のうち主要なものは、概ね次のように分類される。
(1)加圧等により液中に気体を過剰に溶解させたものを減圧状態に導き、過剰溶解分を気体(気泡)として析出させるもの。気泡量は過剰溶解分以上には出来ない。
(2)気体を微量づつ液中に放出するもの。放出口としては微小孔板、メッシュ、連続気泡を有する高分子発泡材、焼結体等が用いられる。生成する気泡径は放出口径よりもかなり大きく、一例では0.2mm径の放出口からの生成気泡径は2mmに達するるので、10μm以下のような微小気泡を作ることは実用的には困難である。
(3)液中に気体を放出し、生成した気液混合物に噴流、旋回等の運動を与えて液/液間の剪断力によって気泡を破砕・微細化するか、或いは気液混合物と器壁・突起等との衝突によって気泡を破砕・微細化するもの。この方法による気泡径は通常400〜500μmであるとされる。静止型混合器と突起とを備えた管中を通液する事により直径10μm以下の気泡が得られるとの提案もあるが、本発明者の経験による限りでは、この方法によって該直径の気泡を定常的に製造することは実用的には困難であると思われる。また、固定円筒中に回転円筒を設置し、円筒間の円管壁状細隙に気液混合物を導入して気泡を微細化する提案或いはこれに磁場作用を付加する提案もあるが、何れも直径10μm以下の気泡を定常的に製造するには不十分である。
(4)超音波等の振動を利用するもの。これには、振動による液圧で気泡を開裂・微細化させるものと、液体−固体界面における固体の振動によって局所的に負圧部分(キャビテイ)をつくり、ここに生ずる減圧気泡と気体との合体によって微小気泡を発生させるものとがあるが、前者は効率的な問題があり、後者で得られている気泡径は10μm以下に到達していない。
(5)上記の方法の何れか2つをを組み合わせて使用する提案においても、直径10μm以下の気泡の製造に十分な結果は得られていない。また、3者以上の方法を組み合わせた提案は見出すことが困難である。 更に、従来の提案においては、生成した気泡の安定性については殆ど関心が払われておらず、実際には界面活性剤を使用しない限り、長時間安定な状態を保持できる微小気泡は得られていない。このため、活性剤等の狭雑物を含まぬ、直径10μm以下の安定した微小気泡を含有する液状物は、気/液或いは気/気反応工程、有機物・無機物の発泡工程等の工業技術、酸素供給を主体とする環境、農業、養殖、食品等の生活技術或いは泡沫消火等の安全技術など、広範囲な応用が期待されるにも拘わらず、従来実用されていない。
【0003】
【発明が解決しようとする課題】本発明は、上記の従来技術における問題点を解決し、直径略10μm以下の安定な微小気泡を長時間保持・含有する水その他の液状物を容易に製造する方法と、各種の有用な微小気泡含有液状物とを提供しようとするものである。
【0004】
【課題を解決するための手段】本発明においては、目的とする微小気泡含有物を得る手段の一つとして、特願2001−247661に記載された液体浄化装置(以下基本装置と言う)を利用する。基本装置は固定筒21の内部に、モータ23により回転軸24を介して駆動される回転筒25を配置し、回転軸の他端は軸受26によって支持される。固定筒21の一方の端部には吸液口27及び吸気口29が設けられ、他方の端部には、固定筒21と外部とを連通するための連通室31が設置される。連通室は連結柱34によって連結された上板31a及び下板31bで構成される。連通室31内にはモータ23により駆動される気液送出装置33を設け、気液送出装置33が作動して連通室31内の気液を外部に送出することにより、連通室31内及び固定筒21内とが負圧となって、吸液口27と吸気口29からそれぞれ液体と気体とが固定筒21内に導入される。気液送出装置は目的に応じて例えば回転翼のような種種の形式のものを用いることが出来る。
【0005】固定筒21の内周面41及び回転筒25の外周面43には、それぞれ長さ方向にほぼ台形の断面を持つ複数本の堤防上突起が設置され、この結果、突起45−45間又は突起47−47間にはほぼ逆台形状の溝49または溝51が形成される。負圧により導入された液体及び気体は、このような固定筒21の内周面41と回転筒25の外周面43とにより形成される空間52を通路として連結室側に導かれる。突起45、47における傾斜面45’、47’の傾斜角a、bは必要に応じて定められるが、通常は20〜60度の範囲にある。
【0006】溝49及び溝51の底面には永久磁石35、37が設置される。永久磁石35、37の設置個所は、必要に応じ突起45の頂面と溝51の底面、或いは溝49の底面と突起47の頂面のような組み合わせが選択される。いずれの場合においても、回転筒25における溝の深さdは、固定筒21における溝の深さcよりも大きく設定される。
【0007】永久磁石35,37の材質は必要に応じ選定されるが、例えばネオジム又はジルコニウムを主材料とするものは本発明の目的に適している。
【0008】固定筒21における吸液口27及び吸気口29の下流側には、モータ23により回転する攪拌装置を設置しこれに伴って逆止弁60を設ける。攪拌装置は例えば回転軸24に固定された2枚の円板65,67の相対する表面の各々に攪拌棒61,63を上下一対として配置した構造又は円板65,67のいずれか一方の攪拌棒を省略した構造とする。攪拌棒は必要に応じ複数個設置され、例えば69,71のような位置に配置される。攪拌棒の全個数又は一部の個数には好ましくは磁界発生手段又はイオン発生手段或いはその双方を備えるものとし、上記磁界発生手段としては例えば永久磁石の設置により、同じく上記イオン発生手段としては例えばトルマリンと誘電セラミックスとよりなる特殊セラミックスないしイオンセラミックス、或いは他の適宜なイオン発生装置の設置により目的を達することが出来る。
【0009】基本装置によって安定な微小気泡含有液状物が得られる過程は、未だ学術的にも十分に解明されていない部分もあり、如何なる理論にも拘束されることを好むものではないが、例えば微小気泡が主として空気によって形成され、液体が水である場合には概ね次のように考えることが出来る。
(A)吸液口27および吸気口29からそれぞれ固定筒21内に導入された水及び空気は、攪拌装置により混和され、空気泡を含む液状物となって固定筒21と回転筒25の間に形成される通路に入る。攪拌装置に磁界発生手段が備えられている場合には、水は磁場を通過するすることによって気泡の微細化に有利な新しい性質を付与される。水に対する磁場の影響については、現象としては認められていても理論的には未だ解明されない部分が多いが、導電性物質としての水が磁場を通過することによって起電力が発生し、水分子が電解若しくはそれに至らぬまでも高いエネルギー状態に保持され、この結果水のクラスターの細分化若しくはクラスター内部構造の変化が生じ、水に新しい性質が与えられるとする見解が有力である。 本装置においては回転筒に設置された永久磁石の回転に伴い磁束が高速移動するため、通常の水の磁化処理装置のように水が磁場内を流動する場合に比べて水と磁場との相対速度は遥かに大きく、起電力の発生に有利である。また、攪拌装置にイオン発生手段が付加されている場合には、液の導電性の増大により起電力の発生を大きなものとする。
(B)固定筒21と回転筒25との間に形成された液体通路断面の半径方向の幅は、21及び25に設けられた突起の頂部が正対した時の頂部間を最狭、其の時の溝底部間を最広として、回転筒の回転に伴って規則的に変動する。この通路に導入された気泡を含む液体は、回転筒の回転による円周方向の激しい運動と、送出手段33の齎す負圧による送出手段側へのやや緩徐な運動との合成により、スパイラル状の軌跡に沿って激しく回転しつつ徐々に連通室31側へ移動する。その間、気泡を含む液体には通路の幅の変動に伴う速度変化によりベルヌイの定理に従う内部圧力の急激な変動が高い週波数で生起し、これによって気泡の著しい細分化を生ずる。
(C)また、気泡を含む液体は、上記通路を移動する間、絶えず固定筒及び回転筒に設けられた突起との衝突によって受ける剪断或いは固定筒及び回転筒に設けられた溝の深さが固定筒側がより深いために起きる内外液間の速度差による剪断の作用を受け、これによっても気泡の細分化を生ずる。
(D)更に、回転筒の回転に伴う液体圧力の高周波変動は、固定筒壁の高調波での共振を惹起し、壁・液界面に生ずるキャビテーションによって気泡はさらに微細化する。
【0010】上記(A)乃至(D)の過程は個々には従来技術における微小気泡製造手段と原理的に一致するものもあるが、本基本装置にあってはこれらの過程が簡易な装置によって逐次又は同時に生起し、導入された気液混合物はスパイラルを描きつつ降下する長い行程中、絶えずそれらの作用を受ける。これにより、基本装置より送出された微細気泡含有液状物中の気泡は直径略10μm以下で、かつ極めて安定で液中で浮上・放散を起こさず、例えば微細気泡が主として空気によって形成され、液体が水である場合には、レーザー光散乱による測定の一例では全気泡中直径5〜10μmのものが約40%、2〜3μmのものが約20%であり、密閉容器中でこの状態が20日以上持続することが観測されている。
【0011】請求項13記載の製造方法は、液体浄化のために開発された基本装置を利用し、必要な改良を加えた製造装置(以下本装置と言う)を用いて、種種の用途を持つ微小気泡含有液状物の製造を行うものである。
【0012】請求項13記載の製造方法において、基本装置78に加える改良は以下の諸点である。
(a)気泡形成に必要な気体の貯蔵槽72を設置し、流速制御装置80を介して基本装置吸気口81に接続する。複数の混合気体によって気泡を形成する場合には、各気体ごとに必要数の貯蔵槽72を設置し、各々流速制御装置80を介して複数設けられた基本装置吸気口に接続するか、若しくは必要があれば各貯蔵槽を各々流速制御装置80を介して一個の混合装置73に結合し、更に混合装置と基本装置吸気口81とを流速制御装置80を介して接続する。常温で液体のもののの蒸気を気泡形成に使用する場合には、当該液体の貯蔵槽及び加熱気化装置を設置し、適当な温度保持手段を講じつつ流速制御装置を介して基本装置吸気口又は混合装置に接続する。必要に応じ気体又は液体の送行路の適当個所に送気ポンプ又は送液ポンプ79を設置する。
(b)必要な液体の貯蔵槽75を設置し、流速制御装置77を介して基本装置吸液口82に接続する。複数の液体を混合して使用する場合には、各液体ごとに必要数の貯蔵槽75を設置し、各々流速制御装置77を介して複数設けられた基本装置吸液口に接続するか、若しくは必要があれば各貯蔵槽75を各々流速制御装置77を介して一個の混合装置74に結合し、更に混合装置と基本装置吸液口82とを流速制御装置77を介して接続する。必要に応じ液体の送行路の適当個所に送液ポンプ76を設置する。
(c)連通室83を気密構造とし、連通室の一端に送出口84を設ける。微小気泡含有液状物を貯蔵する必要がある場合は製品貯蔵槽85を設置し、送出口と連結する。
(d)必要に応じ基本装置回転筒の回転速度を可変とする。
(e)必要に応じ基本装置送出手段の駆動を別途設備されたモータで行い、負圧による気・液の吸引速度を回転筒の回転速度から独立したものとする。
(f)必要に応じ基本装置固定筒溝底面および回転筒溝底面の一方又は双方に発振板を設置し、キャビテーション効果を向上させる。永久磁石の材質及び形状を適宜に選定することにより発振板の機能を付加してもよい。
(g)必要に応じ本装置の全体又は一部に断熱処理を含む温度制御・保持機構を付加する。
本装置の規模は小型可搬式のものから固定施設まで、広範囲に設定することが出来る。
【0013】請求項1記載の微小気泡含有液状物は、液体中に直径略10μm以下の安定な気泡を含有させた液状物であつて、製造方法は特に限定されるものではないが、例えば本装置を用いることにより、確実に製造することが出来る。上記液体としては目的に応じて単一種液体又は複数種液体の混合物を使用することが出来、これらに1種または複数種の添加物を含有させることも出来る。混合物及び添加物含有物の形態としては、溶液の他、ゾルの形態のものも使用可能である。上記気泡を形成する気体としては目的に応じて単一種気体又は複数種気体の混合物を使用することが出来、製造工程に適当な温度制御を施すことにより、常温では気体として存在しないものを気化して使用することもる。通常の気体の他、エアゾルの形態のものも使用可能である。気体と液体との種類及び両者の存在比率は目的に応じて任意に選定される。
【0014】請求項2記載の微小気泡含有液状物は、請求項1の微小気泡が主として空気によって形成されたものであって、製造方法は特に限定されるものではないが、例えば本装置を用いることにより、確実に製造することが出来る。空気と液体との混合比率は目的に応じて任意に選定される。

【発明の実施の形態および実施例】本発明における微小気泡含有液状物は、気/液又は気/気反応工程、有機物・無機物の発泡工程等の工業技術、酸素供給を主体とする環境、農業、養殖、食品等の生活技術或いは泡沫消火等の安全技術など、広範囲にわたり種種の形態で実用が可能である。以下にその実施例を示す。

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microbubble-containing liquid material which is useful or an intermediate product in various technical fields and a method for producing the same.
[0002]
2. Description of the Related Art Many techniques for producing microbubbles in a liquid have been proposed so far, and in recent years, there has been a particular interest in water quality improvement and bathtub-related fields. The main ones of these methods are roughly classified as follows.
(1) A method in which a gas in which a gas is excessively dissolved by pressurization or the like is brought into a reduced pressure state, and an excessively dissolved component is precipitated as a gas (bubbles). The amount of bubbles cannot be more than the excess dissolved amount.
(2) A device that releases a small amount of gas into a liquid. As the discharge port, a microporous plate, a mesh, a polymer foam having open cells, a sintered body, or the like is used. Since the diameter of the generated bubble is considerably larger than the diameter of the discharge port, for example, the diameter of the generated bubble from the discharge port having a diameter of 0.2 mm reaches 2 mm, it is practically difficult to produce microbubbles of 10 μm or less. is there.
(3) The gas is released into the liquid, and the generated gas-liquid mixture is given a motion such as jetting or swirling to break and fine the bubbles by the shear force between the liquid and the liquid, or the gas-liquid mixture and the vessel wall・ Crushing and miniaturizing bubbles by collision with projections. The bubble diameter according to this method is generally considered to be 400 to 500 μm. It has been proposed that bubbles having a diameter of 10 μm or less can be obtained by passing the solution through a tube provided with a static mixer and a projection. However, according to the experience of the present inventor, bubbles having the diameter are reduced by this method. It seems that it is practically difficult to manufacture regularly. In addition, there is a proposal to install a rotating cylinder in a fixed cylinder and introduce a gas-liquid mixture into a cylindrical wall-shaped gap between the cylinders to make air bubbles finer, or to add a magnetic field action to this, It is insufficient to constantly produce bubbles having a diameter of 10 μm or less.
(4) A device utilizing vibration such as ultrasonic waves. This involves breaking and miniaturizing bubbles by the liquid pressure caused by vibration, and creating a negative pressure part (cavity) locally by the vibration of the solid at the liquid-solid interface, and the coalescence of the depressurized bubble and gas generated here. However, the former has an efficient problem, and the bubble diameter obtained in the latter does not reach 10 μm or less.
(5) Even in the proposal using a combination of any two of the above methods, sufficient results for producing bubbles having a diameter of 10 μm or less have not been obtained. Further, it is difficult to find a proposal combining three or more methods. Furthermore, in the conventional proposals, little attention has been paid to the stability of the generated bubbles, and microbubbles capable of maintaining a stable state for a long time have been obtained unless a surfactant is actually used. Absent. For this reason, liquid materials containing stable microbubbles having a diameter of 10 μm or less, which do not contain impurities such as activators, can be produced using industrial technologies such as a gas / liquid or gas / gas reaction process, and a foaming process for organic and inorganic substances. Although it is expected to be used in a wide range of applications, such as environmental technology mainly for oxygen supply, living technology for agriculture, aquaculture, food and the like, and safety technology for foam fire extinguishing, it has not been practically used.
[0003]
SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the prior art and easily produces water and other liquids containing stable microbubbles having a diameter of about 10 μm or less for a long time. It is intended to provide a method and various useful microbubble-containing liquids.
[0004]
In the present invention, a liquid purifying apparatus (hereinafter referred to as a basic apparatus) described in Japanese Patent Application No. 2001-247661 is used as one of means for obtaining a target containing microbubbles. I do. In the basic device, a rotating cylinder 25 driven by a motor 23 via a rotating shaft 24 is disposed inside a fixed cylinder 21, and the other end of the rotating shaft is supported by a bearing 26. A liquid suction port 27 and a suction port 29 are provided at one end of the fixed cylinder 21, and a communication chamber 31 for communicating the fixed cylinder 21 with the outside is provided at the other end. The communication chamber includes an upper plate 31a and a lower plate 31b connected by connecting columns 34. A gas-liquid delivery device 33 driven by the motor 23 is provided in the communication chamber 31, and the gas-liquid delivery device 33 is operated to send out the gas-liquid in the communication chamber 31 to the outside. The inside of the cylinder 21 becomes a negative pressure, and the liquid and the gas are introduced into the fixed cylinder 21 from the liquid suction port 27 and the suction port 29, respectively. As the gas-liquid delivery device, various types such as a rotary wing can be used according to the purpose.
[0005] On the inner peripheral surface 41 of the fixed cylinder 21 and the outer peripheral surface 43 of the rotary cylinder 25, a plurality of embankment protrusions each having a substantially trapezoidal cross section in the longitudinal direction are provided, and as a result, the protrusions 45-45 are provided. A substantially inverted trapezoidal groove 49 or groove 51 is formed between the protrusions or between the protrusions 47-47. The liquid and the gas introduced by the negative pressure are guided toward the connection chamber through the space 52 formed by the inner peripheral surface 41 of the fixed cylinder 21 and the outer peripheral surface 43 of the rotary cylinder 25 as a passage. The inclination angles a and b of the inclined surfaces 45 'and 47' in the projections 45 and 47 are determined as necessary, but are usually in the range of 20 to 60 degrees.
[0006] Permanent magnets 35 and 37 are provided on the bottom surfaces of the grooves 49 and 51. Where the permanent magnets 35 and 37 are installed, a combination such as the top surface of the protrusion 45 and the bottom surface of the groove 51 or the bottom surface of the groove 49 and the top surface of the protrusion 47 is selected as necessary. In any case, the depth d of the groove in the rotating cylinder 25 is set to be larger than the depth c of the groove in the fixed cylinder 21.
The materials of the permanent magnets 35 and 37 are selected as required, but those containing neodymium or zirconium as a main material are suitable for the purpose of the present invention.
A stirrer rotated by the motor 23 is installed downstream of the liquid suction port 27 and the suction port 29 in the fixed cylinder 21, and a check valve 60 is provided accordingly. The stirrer has, for example, a structure in which stirrers 61, 63 are arranged as a pair of upper and lower parts on each of opposing surfaces of two disks 65, 67 fixed to the rotating shaft 24, or stirs one of the disks 65, 67. The rod is omitted. A plurality of stirring rods are provided as necessary, and are arranged at positions such as 69 and 71, for example. The whole number or a part of the stirrer bar preferably includes a magnetic field generating means and / or an ion generating means, and the magnetic field generating means is, for example, a permanent magnet provided. The purpose can be achieved by installing special ceramics or ionic ceramics composed of tourmaline and dielectric ceramics, or other suitable ion generators.
[0009] The process of obtaining a stable liquid containing microbubbles by the basic device has not yet been sufficiently elucidated scientifically, and it is not preferable to be bound by any theory. When the microbubbles are mainly formed by air and the liquid is water, it can be generally considered as follows.
(A) Water and air introduced into the fixed cylinder 21 from the liquid suction port 27 and the suction port 29, respectively, are mixed by a stirrer to form a liquid containing air bubbles. Enter the passage formed at When the stirrer is provided with a magnetic field generating means, water passes through the magnetic field and is given new properties that are advantageous for miniaturization of bubbles. Although the effect of a magnetic field on water has been recognized as a phenomenon, there are many parts that have not been theoretically elucidated yet, but when water as a conductive substance passes through a magnetic field, an electromotive force is generated and water molecules are generated. The prevailing view is that electrolysis or, if not, a high energy state is maintained, which results in the fragmentation of the water clusters or a change in the internal structure of the clusters, giving the water new properties. In this device, the magnetic flux moves at high speed with the rotation of the permanent magnet installed in the rotating cylinder, so the relative position of water and the magnetic field is smaller than when water flows in a magnetic field as in a normal water magnetizer. The speed is much higher, which is advantageous for generating electromotive force. When an ion generating means is added to the stirring device, the generation of electromotive force is increased due to an increase in the conductivity of the liquid.
(B) The radial width of the cross section of the liquid passage formed between the fixed cylinder 21 and the rotary cylinder 25 is the narrowest between the tops when the tops of the projections provided on 21 and 25 face each other. The distance between the groove bottoms at the time of (1) is the widest, and fluctuates regularly with the rotation of the rotary cylinder. The liquid containing bubbles introduced into this passage is formed into a spiral shape by a combination of a violent movement in the circumferential direction due to the rotation of the rotary cylinder and a slightly slower movement toward the sending means due to the negative pressure caused by the sending means 33. While rotating violently along the trajectory, it gradually moves to the communication chamber 31 side. In the meantime, in the liquid containing bubbles, a sudden change in the internal pressure according to Bernoulli's theorem occurs at a high frequency due to a change in velocity with a change in the width of the passage, thereby causing significant fragmentation of the bubbles.
(C) In addition, the liquid containing air bubbles is constantly sheared by collision with the projections provided on the fixed cylinder and the rotating cylinder while moving through the passage, or the depth of the groove provided on the fixed cylinder and the rotating cylinder is reduced. Due to the velocity difference between the inner and outer liquids caused by the deeper fixed cylinder side, shearing action is also caused, which also causes fragmentation of bubbles.
(D) Further, the high frequency fluctuation of the liquid pressure accompanying the rotation of the rotary cylinder causes resonance of the fixed cylinder wall at higher harmonics, and the bubbles are further miniaturized by cavitation generated at the wall-liquid interface.
The above steps (A) to (D) may in principle correspond to the microbubble producing means in the prior art, but in the present basic apparatus, these steps are performed by a simple apparatus. Sequentially or simultaneously occurring, the introduced gas-liquid mixture is constantly affected by it during a long stroke descending in a spiral. Thereby, the bubbles in the liquid containing fine bubbles sent from the basic device have a diameter of about 10 μm or less, and are extremely stable and do not float or diffuse in the liquid. For example, the fine bubbles are mainly formed by air, and the liquid is In the case of water, in an example of measurement by laser light scattering, about 40% of all bubbles have a diameter of 5 to 10 μm, and about 20% of those having a diameter of 2 to 3 μm. It has been observed that this persists.
According to a thirteenth aspect of the present invention, there is provided a manufacturing method which utilizes a basic apparatus developed for liquid purification and has various uses by using a manufacturing apparatus (hereinafter referred to as the present apparatus) with necessary improvements. This is for producing a liquid material containing microbubbles.

Connect to device. If necessary, an air supply pump or a liquid supply pump 79 is installed at an appropriate place in the gas or liquid passage.
