[0003] 例えば、特許第 3227567号公報 (特許文献 1)には、回転式散水板と導水板とによ り遠心ポンプを構成し、外部筒に設けられた吸気孔力 空気を、吸水口から処理対 象水をそれぞれ吸引し、内部筒の高速回転により激しい渦流により空気を処理対象 水に混合して無数の微小な気泡を発生させ、更に散水板の回転により分割、微小化 させ、更に散水板や外部筒内面、内部筒外面等に設けた永久磁石によるボンビング 作用と電磁作用との相乗作用によりサブミクロン(10, 000分の 1ミリメートル; 10_7) オーダーの極微細気泡を処理対象水中に生成し、気泡中の酸素成分をより多く処理 対象水中に溶け込ませることで水質浄ィ匕を図ることが記載されて 、る。 [0003] For example, in Japanese Patent No. 3227567 (Patent Document 1), a centrifugal pump is constituted by a rotating water spray plate and a water guide plate, and air suction force air provided in an external cylinder is supplied from a water intake port. Water to be treated is sucked in, the air is mixed with the water to be treated by vigorous vortex flow due to the high speed rotation of the inner cylinder to generate countless minute bubbles, and further divided and miniaturized by the rotation of the water spray plate.

[0004] また、特開 2003— 053373号公報 (特許文献 2)には、固定筒の内周面と回転筒 の外周面とにそれぞれ断面略台形状の突条を該固定筒ないし回転筒の長さ方向に 複数本形成することにより、これら各突条間を断面略逆台形状の溝とし、これら各溝 内に永久磁石を配設したものが提案されて ヽる。  [0004] Further, Japanese Patent Laid-Open No. 2003-053373 (Patent Document 2) discloses protrusions having a substantially trapezoidal cross section on the inner peripheral surface of the fixed cylinder and the outer peripheral surface of the rotary cylinder, respectively.

発明が解決しょうとする課題  Problems to be solved by the invention
[0006] し力しながら、生成する気泡が小さければ小さいほど、水域中に長時間留まってい ることが出来、水域全般に拡散することが出来るため水質浄ィ匕作用に寄与するが、 前述の特許文献 1の技術では、内部筒及び散水板を固定した回転軸を水中モータ の回転軸に連結して回転させる構成であったため、内部筒及び散水板の回転数が 水中モータの回転数 (例えば 1500回転 Z分〜 3600回転 Z分程度)に拘束されてし まい、十分な高速運転が得られないためナノ(1, 000, 000分の 1ミリメートル; 10_9) オーダーの超極微細気泡を得ることが出来な力つた。 [0006] However, the smaller the bubbles generated, the longer they remain in the water area. However, in the technology of Patent Document 1 described above, the rotating shaft with the inner cylinder and watering plate fixed is used as the rotating shaft of the submersible motor. Since it is connected and rotated, the rotation speed of the inner cylinder and the water spray plate is restricted by the rotation speed of the submersible motor (for example, about 1500 rpm Z to 3600 rpm Z), and sufficient high-speed operation is obtained. It was not possible to obtain ultra-fine bubbles of nano (1,000,000 / millimeter; 10 _9 ) order.
[0007] また、イオン水精製を重視したと見られる、特許文献 2も磁石量を多くすることにより 、起動時に大きな回転トルクが必要となる上、水中モータの回転数が 1800回転以下 でしか運転できず、これにより特許文献 1よりも気泡自体は大きな気泡となってしまう。 即ち、磁力を大きくするとイオンィ匕効果が増大するが、その反面、負荷が大きくなつて 回転数が上がらず気泡の微細化効果が低減するという相反する関係となってしまい 、結果的に特許文献 1, 2の技術では微細気泡の発生原理が判然とせず、回転体と 磁力と気泡との相互関係が全く解らない状態であった。  [0007] In addition, Patent Document 2, which is considered to place importance on ionic water purification, requires a large rotational torque at the start-up by increasing the amount of magnets and operates only when the rotational speed of the submersible motor is 1800 revolutions or less. As a result, the bubbles themselves are larger than those in Patent Document 1. In other words, when the magnetic force is increased, the ionic effect increases, but on the other hand, the load becomes large and the rotational speed does not increase and the effect of reducing the size of bubbles is reduced. In the techniques of No. 2 and No. 2, the principle of generation of fine bubbles was not clear, and the interrelationship between the rotating body, magnetic force and bubbles was not understood at all.
[0008] 本発明は前記課題を解決するものであり、その目的とするところは、回転駆動源の 回転数に拘束されることなく、それ以上の高速回転により回転部を回転させてナノ( 1 , 000, 000分の 1ミリメートル; 10_9)オーダーの超極微細気泡を得ることが出来る泡 発生装置を提供せんとするものである。 [0008] The present invention solves the above-described problems, and an object of the present invention is to rotate the rotating portion by high-speed rotation beyond that without being restricted by the rotational speed of the rotational drive source. , 000,000 / 000 millimeters; 10 _9 ) A bubble generator capable of obtaining ultrafine bubbles of the order is to be provided.

[0010] 前記目的を達成するための本発明に係る泡発生装置の第 2の構成は、前記第 1の 構成において、前記空転許容手段は、前記回転駆動源により回転する第 1の回転体 と、該第 1の回転体に対向する前記回転部の一端部との対向面にそれぞれ互いに 磁力による引力が作用するように設けられた一対の第 1の異極磁石と、前記回転駆 動源により回転する第 2の回転体と、該第 2の回転体に対向する前記回転部の他端 部との対向面にそれぞれ互 ヽに磁力による弓 I力が作用するように設けられた一対の 第 2の異極磁石とを有して構成したことを特徴とする。 [0010] A second configuration of the foam generating apparatus according to the present invention for achieving the above object is that, in the first configuration, the idling permission means is a first rotating body that is rotated by the rotation drive source; A pair of first different magnets provided so that attractive force due to a magnetic force acts on a surface facing the one end of the rotating unit facing the first rotating body, and the rotation driving source. A pair of first rotators provided so that a bow I force by a magnetic force acts on the opposing surfaces of the rotating second rotating body and the other end of the rotating part facing the second rotating body. It is characterized by having two different pole magnets.
[0011] 前記目的を達成するための本発明に係る泡発生装置の第 3の構成は、前記第 1の 構成において、前記第 1、第 2の回転体の少なくとも何れか 1つにポンプ羽根が設け られたことを特徴とする。  [0011] A third configuration of the foam generating apparatus according to the present invention for achieving the above object is that, in the first configuration, a pump blade is provided in at least one of the first and second rotating bodies.

発明の効果  The invention's effect
[0012] 本発明に係る泡発生装置の第 1の構成によれば、回転駆動源により回転部に回転 駆動力を付与して回転させた後、空転許容手段により該回転部の空転を許容すると 共に、外筒と回転部との対向面にそれぞれ設けた第 1、第 2の同極磁石による斥力を 作用させて、回転部をそれ以上に高速回転 (例えば 3600回転 Z分〜 10, 000回転 Z分)させることが出来、これによりナノ(1, 000, 000分の 1ミリメートル; 10_9)オーダ 一の超極微細気泡を得ることが出来る。 [0012] According to the first configuration of the foam generating device of the present invention, after rotating the rotating part by applying a rotational driving force to the rotating part by the rotation driving source, the idling of the rotating part is permitted by the idling permission means. In both cases, the rotating part rotates at a higher speed (for example, 3600 rotations Z min to 10,000 rotations) by applying repulsive force by the first and second homopolar magnets provided on the opposing surfaces of the outer cylinder and the rotating part, respectively. Z minute), and this makes it possible to obtain nano ( 1,000,000 / 000 millimeters; 10 _9 ) ultrafine bubbles.
[0013] 即ち、第 1、第 2の同極磁石同士が対面した状態で互いの対向面が平行になるよう 配置され、且つ外筒及び回転部でそれぞれ互いに隣設される磁石同士は、該それ ぞれの磁石表面を含む平面同士が、第 1、第 2の同極磁石同士が対面して力 離れ る迄に発生する斥力による回転増速力が、第 1、第 2の同極磁石同士が近づいて対 面する迄に発生する斥力による回転抑止力よりも大きくなる所定の角度で交差するよ うに設定されたことにより、第 1、第 2の同極磁石同士が対面する際に発生する斥力 により回転駆動源の回転数よりも大きな回転数で回転部の回転速度を増速すること が出来、第 1、第 2の同極磁石同士がすれ違う際に発生する反発力による回転抑止 力よりも回転増速力が大きくなるため共振共鳴により回転駆動源の回転数よりも大き な回転数で回転しょうとする回転部の回転増速作用を連続的に発生することが出来 る。 That is, the first and second homopolar magnets facing each other are arranged so that their opposing surfaces are parallel to each other, and the magnets adjacent to each other in the outer cylinder and the rotating part are The rotational acceleration force due to the repulsive force generated until the planes including the respective magnet surfaces face each other and the first and second homopolar magnets face each other is separated from each other by the first and second homopolar magnets. Occurs when the first and second homopolar magnets face each other because they are set to intersect at a predetermined angle that is greater than the rotational deterrent force generated by the repulsive force that occurs until the two face each other. The rotational speed of the rotating part is increased at a rotational speed greater than the rotational speed of the rotational drive source by repulsive force. The rotational acceleration force is greater than the rotational deterrence force due to the repulsive force that occurs when the first and second homopolar magnets pass each other, so resonance resonance causes the rotational speed to be greater than the rotational speed of the rotational drive source. It is possible to continuously generate the rotational acceleration action of the rotating part that is to rotate.
[0014] また、本発明に係る泡発生装置の第 2の構成によれば、第 1、第 2の異極磁石の引 力により回転部を外筒の内部で宙吊り状態で支持することが出来、しかも異極磁石 の引力により高速回転する回転部の回転位置を安定して支持することが出来る。  [0014] In addition, according to the second configuration of the foam generating apparatus of the present invention, the rotating portion can be supported in a suspended state inside the outer cylinder by the attractive force of the first and second heteropolar magnets. In addition, the rotational position of the rotating part that rotates at a high speed can be stably supported by the attractive force of the heteropolar magnet.
[0015] また、本発明に係る泡発生装置の第 3の構成によれば、回転駆動源によりポンプ羽 根を回転させて外筒内を負圧にすることが出来、外筒に設けられた吸液口と吸気口 から液体と気体とを外筒内に導き、高速回転する回転部により混合させてナノ(1, 00 0, 000分の 1ミリメートル; 10_9)オーダーの超極微細気泡を得ることが出来る。 図面の簡単な説明 [0015] In addition, according to the third configuration of the foam generating device of the present invention, the pump blade can be rotated by a rotational drive source so that the pressure inside the outer cylinder can be made negative, and is provided in the outer cylinder. Liquid and gas are introduced into the outer cylinder from the suction port and the suction port, and mixed by a rotating part that rotates at high speed to create ultrafine bubbles of nano ( 1,000,000 / millimeter; 10 _9 ) order. Can be obtained. Brief Description of Drawings

[0040] 前述した構成を有する泡発生装置 1は、例えば、処理対象水内に設置して水質浄 化装置として作用させることが出来る。吸気口 18は図示しない吸気管を介して外気に 連通されて外筒 3内に空気を取り入れ、吸液口 2は泡発生装置 1が設置される処理 対象水を取り入れる。吸気管としては長尺且つ可撓性性の管体 (ホース)を用いて構 成することが出来、外気に連通する剛性の管体を用いて構成することも出来る。吸気 管の数は 1個或いは複数設けることが出来る。  [0040] The foam generating device 1 having the above-described configuration can be installed in the water to be treated, for example, to act as a water purification device. The intake port 18 communicates with the outside air through an intake pipe (not shown) to take air into the outer cylinder 3, and the liquid intake port 2 takes in water to be treated in which the foam generating device 1 is installed. The intake pipe can be configured using a long and flexible tube (hose), or can be configured using a rigid tube communicating with the outside air. One or more intake pipes can be provided.
[0041] 外筒 3のポンプ羽根 17に対応する部位には排出口 3aが設けられており、ポンプ羽 根 17により送り出されたナノ(1, 000, 000分の 1ミリメートル; 10_9)オーダーの極微 細気泡を含有する処理対象水が外部に送出される。 [0041] A discharge port 3a is provided in a portion of the outer cylinder 3 corresponding to the pump blade 17 and is in the order of nano ( 1,000,000 / millimeter; 10 _9 ) delivered by the pump blade 17 Water to be treated containing ultrafine bubbles is sent to the outside.
[0042] 吸液口 2の外側には、不測のゴミ流入防止のために、金網等のゴミ除 (よ)けを付設 することも出来る。  [0042] To prevent unexpected inflow of dust, a dust screen such as a wire mesh can be attached to the outside of the liquid suction port 2.
[0043] 回転部 4の回転反発用磁石 16は、図 2及び図 4に示すように、該回転部 4の円周方 向に所定のピッチで設けられた断面台形状の突起部 4aの傾斜面に取り付けられて おり、この突起部 4aが遠心ポンプにおける回転羽根の役割も兼ねる。 [0043] As shown in FIGS. 2 and 4, the rotational repulsion magnet 16 of the rotating part 4 is arranged in the circumferential direction of the rotating part 4. Is attached to the inclined surface of the projection portion 4a of the trapezoidal shape provided at a predetermined pitch in direction, the protrusion 4 a is also function of the rotary vane of the centrifugal pump.
[0044] 回転部 4の外周面と外筒 3の内周面との間に形成された間隙 19において吸気口 18 力 吸入した空気を吸液口 2から吸入した処理対象水に混合させて無数の微小な気 泡を生成させると共に、該各気泡中の酸素成分を該処理対象水中に溶解させる。  [0044] In the gap 19 formed between the outer peripheral surface of the rotating part 4 and the inner peripheral surface of the outer cylinder 3, the intake air 18 force is mixed with the water to be treated sucked from the liquid suction port 2 and innumerable And the oxygen component in each bubble is dissolved in the water to be treated.
[0045] 水中モータ 8を回転させると、回転軸 8aに接続された連結部材 5、ポンプ羽根 17、 支軸部材 7及び拘束部材 12に回転駆動力が伝達され、異極磁石 10, 11, 13, 14の作 用により回転部 4がポンプ羽根 17及び拘束部材 12の回転に連れ回りすることにより水 中モータ 8と回転部 4とが一体的に回転する。  When the submersible motor 8 is rotated, the rotational driving force is transmitted to the connecting member 5, the pump blade 17, the support shaft member 7, and the restraining member 12 connected to the rotating shaft 8 a, and the different polarity magnets 10, 11, 13 , 14 causes the rotating part 4 to rotate with the rotation of the pump blade 17 and the restraining member 12, so that the underwater motor 8 and the rotating part 4 rotate integrally.
[0046] 水中モータ 8の回転数は例えば 1800回転 Z分〜 3600回転 Z分程度のものが使 用され、これに従って回転部 4の回転数も先ずは 1800回転 Z分〜 3600回転 Z分 程度で回転する。水中モータ 8が最大回転数に達した後は、空転許容手段となるポ ンプ羽根 17及び拘束部材 12と回転部 4の両端部に設けられた異極磁石 10, 11, 13, 14による磁力による引力よりも、外筒 3の内周面に設けられた固定反発用磁石 15と回 転部 4の外周面に設けられた回転反発用磁石 16との磁力による斥力が大きいため回 転部 4は水中モータ 8の最大回転速度を超えて増速され超高速回転で回転する。  [0046] The rotation speed of the submersible motor 8 is, for example, about 1800 rotation Z minutes to 3600 rotation Z minutes, and according to this, the rotation speed of the rotating unit 4 is also about 1800 rotation Z minutes to 3600 rotation Z minutes. Rotate. After the submersible motor 8 reaches the maximum number of revolutions, the pump blade 17 and the restraining member 12 that serve as idling allowance means and the magnetic force generated by the opposite pole magnets 10, 11, 13, 14 provided at both ends of the rotating part 4 Since the repulsive force due to the magnetic force between the fixed repulsion magnet 15 provided on the inner peripheral surface of the outer cylinder 3 and the rotary repulsion magnet 16 provided on the outer peripheral surface of the rotating portion 4 is larger than the attractive force, the rotating portion 4 is Underwater motor 8 is increased beyond the maximum rotation speed and rotates at ultra-high speed.
[0047] 一方、水中モータ 8と一体的に回転するポンプ羽根 17により遠心ポンプと同様な役 割を果たす。即ち、ポンプ羽根 17が回転すると、間隙 19に連通された隙間 20内の処 理対象水がポンプ羽根 17により図 1の上下方向に搔き出されて排出口 3aから外部に 放出され、隙間 20内の水圧が低下して大気圧以下 (負圧)となる。  On the other hand, the pump blade 17 that rotates integrally with the submersible motor 8 performs the same function as the centrifugal pump. That is, when the pump blade 17 rotates, the water to be treated in the gap 20 communicated with the gap 19 is pumped up and down in FIG. 1 by the pump blade 17 and discharged from the discharge port 3a to the outside. The water pressure inside decreases to below atmospheric pressure (negative pressure).
[0048] そのため、隙間 20に連通する間隙 19内も負圧となって外筒 3内の水面が降下し、吸 気口 18力 空気が流入すると共に、吸液口 2から処理対象水が流入する。  [0048] Therefore, the pressure in the gap 19 communicating with the gap 20 also becomes negative, the water surface in the outer cylinder 3 falls, the suction port 18 force air flows in, and the water to be treated flows from the liquid suction port 2 To do.
[0049] 間隙 19内に流入した処理対象水は回転部 4の高速回転に引き摺られて高速で回 転する。それによつて、外筒 3内における降下した水面は激しく波立つと同時に泡立 ち、当該水面下では 2次流れとしての無数の小渦が発生する。この時の渦発生現象 はティラー渦流れ (Taylor Couette Flow或いは Taylor Vortex)と呼ばれている現象で ある。  The water to be treated that has flowed into the gap 19 is dragged by the high-speed rotation of the rotating unit 4 and rotates at a high speed. As a result, the descending water surface in the outer cylinder 3 undulates and bubbles at the same time, and countless small vortices are generated as secondary flows below the water surface. The vortex generation phenomenon at this time is a phenomenon called Taylor Couette Flow (Taylor Couette Flow or Taylor Vortex).
[0050] ここで、ティラー渦とは、大きな円筒力もなる外筒 3とその中に小さな円筒或いは円 柱力もなる回転部 4があり、その 2つに挟まれた空間である間隙 19には処理対象水が 満たされており、回転部 4の回転により、その付近の処理対象水は遠心力を受けて外 筒 3方向へ押し出される。そして、状態平衡を保つように処理対象水には作用'反作 用力が働き、外側へ押し出される一方で、回転部 4側へ戻ってくる作用が起きる。こ れにより無数の小渦が発生する。 [0050] Here, the Tiller vortex is an outer cylinder 3 having a large cylindrical force and a small cylinder or circle in the outer cylinder 3. There is a rotating part 4 that also has column force, and the space 19 that is sandwiched between the two is filled with water to be treated, and the water to be treated nearby receives centrifugal force due to the rotation of the rotating part 4. Is pushed out in three directions. In order to maintain the state equilibrium, the water to be treated has an action / reaction force that is pushed outward while returning to the rotating part 4 side. As a result, countless small vortices are generated.
[0051] そのため、吸気口 18力 流入した空気は吸液口 2から流入した処理対象水に効率 的に混合され、無数の微小な気泡となる。また、発生した各微小気泡中の酸素成分 は酸素不足の当該処理対象水中に効率的に溶け込む。  [0051] Therefore, the air that has flowed into the intake port 18 is efficiently mixed with the water to be treated that has flowed in from the liquid suction port 2 to form countless minute bubbles. In addition, the oxygen component in each generated microbubble is efficiently dissolved in the water to be treated that is deficient in oxygen.
[0052] 間隙 19内の処理対象水は微小気泡の数と溶解酸素の量とを増カロさせながら固定 反発用磁石 15と回転反発用磁石 16による電磁作用との相乗作用を受けて該間隙 19 内に流入した処理対象水中の全ての微小気泡について分割と再分割とがなされ、ナ ノ(1, 000, 000分の 1ミリメートル; 10_9)オーダーの極微細気泡が生成されると共 に、該各極微細気泡中の酸素成分が処理対象水中に更に溶解される。 [0052] The water to be treated in the gap 19 is subjected to a synergistic effect of the electromagnetic action of the fixed repulsion magnet 15 and the rotary repulsion magnet 16 while increasing the number of microbubbles and the amount of dissolved oxygen. All microbubbles in the water to be treated that flowed into the inside are divided and subdivided to generate nano- sized bubbles of the order of nano ( 1,000,000 / millimeter; 10 _9 ). The oxygen component in each ultrafine bubble is further dissolved in the water to be treated.
[0053] 極微細気泡と溶解酸素を含んだ処理対象水は、ポンプ羽根 17の回転によるポンピ ング作用によって、排出口 3aから図 1の上下方向に放出され、泡発生装置 1が設置 された処理対象水域に拡散される。このようにして成る極微細気泡と溶解酸素とは、 処理対象水域内から短時間で浮上してしまうことがなぐ同水域中に極めて長時間 留まって!/ヽることが出来、同水域全般に拡散することが出来る。  [0053] The water to be treated containing ultrafine bubbles and dissolved oxygen is discharged from the discharge port 3a in the vertical direction in FIG. 1 by the pumping action caused by the rotation of the pump blades 17, and the foam generator 1 is installed. Spread to the target water area. The ultrafine bubbles and dissolved oxygen formed in this way stay in the water area for a very long time without rising in a short time from within the water area to be treated! Can diffuse.
[0054] 本発明による泡発生装置 1は、水中モータ 8の最大回転数を超えて空転許容手段 となるポンプ羽根 17及び拘束部材 12と回転部 4の両端部に設けられた異極磁石 10, 11, 13, 14による磁力による引力による結合により空転が許容され、空転された回転 部 4は回転反発用磁石 16と固定反発用磁石 15とにより作用する斥力により水中モー タ 8の最大回転速度を超える超高速回転を実現したことにより、気泡微細化の程度に おいて、また、極微細気泡と溶解酸素の滞水時間の長さにおいて、前述の従来の特 許文献 1, 2に記載された技術よりも格段に優れている事実が本発明者等によって実 験的に確認されたものである。  [0054] The foam generating device 1 according to the present invention includes a pump blade 17 and a restraining member 12 that serve as idling allowance means exceeding the maximum number of rotations of the submersible motor 8, and different polar magnets 10 provided at both ends of the rotating unit 10. The rotating part 4 that has been idled is allowed to rotate at the maximum rotational speed of the underwater motor 8 by the repulsive force acting by the rotating repulsion magnet 16 and the fixed repulsion magnet 15. As a result of achieving ultra-high-speed rotation exceeding that described in the conventional patent documents 1 and 2 described above, in terms of the degree of bubble miniaturization and the length of time of stagnant ultrafine bubbles and dissolved oxygen. The fact that it is far superior to the technology has been experimentally confirmed by the present inventors.
[0055] 各個の水分子は、良く知られているように、水素 酸素一水素の結合状態が、直線 的でなぐ且つ、電子の確率分布が対称でなぐ電気双極子を成している。それ故、 それらの水分子は、液相では単体では存在せず、水素結合により幾つかが寄り集ま つてクラスターを形成している。クラスターの大きさや形は、溶存する不純物の種類や 量、それに温度によって、様々に変化する。 [0055] As is well known, each water molecule forms an electric dipole in which the bonding state of hydrogen and oxygen is not linear and the probability distribution of electrons is symmetric. Therefore, These water molecules do not exist alone in the liquid phase, and some of them gather together due to hydrogen bonding to form a cluster. The size and shape of the cluster varies depending on the type and amount of dissolved impurities and the temperature.
[0056] 電気双極子を成す水分子 (イオン水)は、外筒 3の内周面と回転部 4の外周面と〖こ それぞれ設けられた固定反発用磁石 15及び回転反発用磁石 16による磁界との相対 運動、更にはその相対運動が与えられると、それによつてエネルギー(主に分子の回 転運動のエネルギー、それに伸縮運動や並進運動のエネルギー)が与えられ、エネ ルギー準位が引き上げられる。  [0056] The water molecules (ionic water) forming the electric dipoles are magnetic fields generated by the fixed repulsion magnet 15 and the rotation repulsion magnet 16 provided on the inner peripheral surface of the outer cylinder 3 and the outer peripheral surface of the rotating part 4, respectively. When given relative motion, and then relative motion, energy (mainly molecular rotational energy, stretching and translational energy) is given, and the energy level is raised. .
[0057] 即ち、水分子が活性化された結果、当該水分子のクラスターはより小さくなり、従つ て、極微細気泡中の酸素がクラスタ一間に溶け込み易くなり、また、極微細気泡が分 割され易くなる。更に、導電性流体である処理対象水と磁場とが相対運動をすると、 処理対象水中に電流が誘起する。同時に、 B2/2 μの等方的な圧力(磁気圧)と、 Β 2Ζ の磁力線の方向(ここでは垂直方向)への張力とが発生する。尚、 Βは磁力の 強さ、 μは磁束の透磁率である。これらの現象もまた、水分子のクラスターをより小さく する。  That is, as a result of the water molecule being activated, the water molecule cluster becomes smaller, so that oxygen in the ultrafine bubbles easily dissolves between the clusters, and the ultrafine bubbles are separated. It becomes easy to be cracked. Furthermore, when the water to be treated, which is a conductive fluid, and the magnetic field move relative to each other, an electric current is induced in the water to be treated. At the same time, an isotropic pressure (magnetic pressure) of B2 / 2 μ and a tension in the direction of the magnetic field line of Β 2Ζ (here, the vertical direction) are generated. Here, 強 is the strength of the magnetic force, and μ is the magnetic permeability of the magnetic flux. These phenomena also make water molecule clusters smaller.
[0058] 一方、酸素分子は磁気双極子を成す常磁性であるから固定反発用磁石 15と回転 反発用磁石 16とにより形成される磁界との相対運動が与えられると、それによつてェ ネルギー(主に分子の回転運動のエネルギー、それに並進運動のエネルギー)が与 えられエネルギー準位が引き上げられる。その結果、磁界内の酸素分子は活性化さ れ、気泡表面の酸素分子は水の境界面を突破してその中に溶け込み易くなる。  [0058] On the other hand, since oxygen molecules are paramagnets forming a magnetic dipole, when relative motion between the magnetic field formed by the stationary repulsion magnet 15 and the rotation repulsion magnet 16 is given, the energy ( The energy level is raised mainly by the energy of the rotational motion of the molecule and the energy of the translational motion. As a result, oxygen molecules in the magnetic field are activated, and oxygen molecules on the bubble surface break through the boundary surface of water and easily dissolve in it.
[0059] 処理対象水中に放出された極微細気泡の直径が微細化すればするほど全ての極 微細気泡が短時間で水面に浮上してしまうことがなぐ従ってその滞水時間が限りな く長くなり極微細気泡全体の表面積、即ち極微細気泡全体と処理対象水との接触面 積が限りなく大きくなる。  [0059] As the diameter of the ultrafine bubbles released into the water to be treated becomes finer, all the ultrafine bubbles do not float on the water surface in a short time. Therefore, the surface area of the entire ultrafine bubbles, that is, the contact area between the entire ultrafine bubbles and the water to be treated becomes extremely large.
[0060] このように、処理対象水中域に拡散されたイオン水は、種々の対象物を効率的に酸 化 (Ν極反発)または、アルカリ化(S極反発)する。酸ィ匕によって生じたイオン水は、病 原菌ゃ微生物だけを殺菌する。アルカリ化によって生じたイオン水は、タンパク質や 油脂分の分解をし優れた洗浄力を発揮する。 [0061] また、太陽光が存在するときは浮遊性の藻類 (例えばァォコ等)を死滅'凝集させる ことが出来る。浮遊性藻類の死滅'凝集によって生じた微小浮遊物質は気泡と付着し て水面に浮上し、浮上スカム(かす)と成る。更に、この極微細気泡は水底のへドロ( 微生物層)に無数に結合してそれらに浮力を与え、大きな単位で浮上させることも出 来る。 [0060] Thus, the ionized water diffused into the water area to be treated efficiently oxidizes (extreme repulsion) or alkalins (solar repulsion) various objects. The ionic water produced by the acid will kill only the microorganisms. Ionized water generated by alkalinization decomposes proteins and fats and oils and exhibits excellent cleaning power. [0061] In addition, when sunlight is present, planktonic algae (for example, cocoons) can be killed and aggregated. Death of floating planktonic algae 'Floating matter produced by agglomeration adheres to bubbles and floats on the surface of the water, forming floating scum. In addition, these microbubbles can bind to countless sludge (microbe layer), give them buoyancy, and float in large units.
[0062] 尚、浮上スカムは定期的に捕集され、且つ廃棄されることによって対象水域につい ての水質浄化処理が達成される。  [0062] The floating scum is periodically collected and discarded to achieve the water purification process for the target water area.
[0063] また、外筒 3の内周面及び回転部 4の外周面に設けられた固定反発用磁石 15及び 回転反発用磁石 16の働きによって間隙 19内の各点において回転部 4の半径方向の 磁界が発生しており、前述した磁界と水分子との相互作用、誘起電流と水分子との 相互作用、並びに磁界と酸素分子との相互作用、そしてそれらの相乗効果によって 、より微細な気泡を間隙 19内の処理対象水中に生成させ、また、該極微細気泡中の 酸素成分をより多く該処理対象水中に溶解させることが出来る。  [0063] In addition, the fixed repulsion magnet 15 and the rotation repulsion magnet 16 provided on the inner peripheral surface of the outer tube 3 and the outer peripheral surface of the rotation portion 4 act in the radial direction of the rotation portion 4 at each point in the gap 19. The magnetic field is generated, and the finer bubbles are generated by the above-described interaction between the magnetic field and water molecules, the interaction between the induced current and water molecules, and the interaction between the magnetic field and oxygen molecules, and their synergistic effect. Can be produced in the water to be treated in the gap 19 and more oxygen components in the ultrafine bubbles can be dissolved in the water to be treated.
[0064] 上記泡発生装置 1に各種気体発生装置を適宜併用することが出来る。例えば、ォ ゾン発生装置または活性空気発生装置は地上に設置され、長尺且つ可撓性の吸気 管を介して外筒 3の吸気口 18に気密且つ水密に接続される。  [0064] Various gas generators can be used in combination with the bubble generator 1 as appropriate. For example, the ozone generator or the active air generator is installed on the ground, and is airtight and watertightly connected to the intake port 18 of the outer cylinder 3 through a long and flexible intake pipe.
[0065] 吸気管は処理対象水域景観が損われることがないようにするために、運転時には 同水域の水面下に敷設される。それらの装置で発生したオゾン或いは活性空気は可 橈性の吸気管から吸気口 18を介して外筒 3の内部に送り込まれる。 [0065] The intake pipe is laid under the surface of the water area during operation so that the scenery of the water area to be treated is not damaged. Ozone or active air generated in these devices is sent from the flexible intake pipe into the outer cylinder 3 through the intake port 18.
[0066] 外気の代りに、オゾン入りの空気または活性空気を吸気口 18に送り込むことにより、 それらと極微細気泡化との相乗作用によって、水質浄化作用を更に増進させることが 出来る。 [0066] By sending ozone-containing air or active air into the intake port 18 instead of outside air, the water purification effect can be further enhanced by the synergistic effect of these and the formation of microbubbles.
[0067] 処理対象水域に雨水等が流入してその水面が変動すると、吸気口 2の水深と水圧 が変動して処理対象水と空気との最適な混合比が崩れる場合があるため処理対象 水域の水面変動に対応して泡発生装置 1本体を適宜の浮子に結合して水底から浮 上させ、水面が変動したときでも同泡発生装置 1本体の水深位置が変動しないように 、また、吸気口 2の水深と水圧が変動しないようにすることが出来る。  [0067] When rainwater or the like flows into the water area to be treated and its water level fluctuates, the water depth and water pressure at the inlet 2 may fluctuate, and the optimal mixing ratio of the water to be treated and air may collapse. In response to the water level fluctuation, the foam generator 1 is connected to an appropriate float and floated from the bottom of the water, so that the water depth position of the foam generator 1 body does not fluctuate even when the water level fluctuates. It is possible to prevent the water depth and water pressure at mouth 2 from fluctuating.
[0068] 処理対象水の汚れや酸性化が酷!、時は、即時の改善を計るために、初めの期間 のみであるが、中和剤及び Zまたは凝集剤等の薬剤を散水または散布することが出 来る。これによつて有機物が強制浮上され、 pH度が改善される。薬剤による改善後 は泡発生装置 1によって水質浄ィ匕を続行することが出来る。水質浄化がある程度進 んだ段階でバクテリア (好気性バクテリア或 、はアンモニア分解バクテリア)を投入す る。以上の相乗効果によって処理対象水を十分に水質浄化することが出来る。 [0068] The water to be treated is heavily soiled and acidified! Sometimes it is the first period to measure immediate improvement. However, it is possible to spray or spray chemicals such as neutralizing agents and Z or flocculants. As a result, the organic matter is forcedly levitated and the pH is improved. After improvement with chemicals, water purification can be continued with the foam generator 1. Bacteria (aerobic bacteria or ammonia-degrading bacteria) are introduced after water purification has progressed to some extent. The water to be treated can be sufficiently purified by the above synergistic effect.
