A diffusion chamber for diffusing the mixed fluid of hydrogen supplied to the gas, a porous element filled in the diffusion chamber and having a predetermined pore diameter for passing the supplied hydrogen as fine bubbles, and the other of the tube An apparatus for producing hydrogenated water containing a large amount of hydrogen as fine bubbles, which is provided with a discharge port for discharging the produced hydrogenated water formed at the end, has been proposed (for example, see Patent Document 1).

　しかしながら、特許文献１に記載の水素水製造装置では、特許文献１に記載されているように、製造される水素水における水素ガスの気泡の直径は、２μｍ程度が限界となる。水素ガスの気泡の直径は小さければ小さいほど水素水の特性が向上するため、さらなる気泡の小型化がのぞまれている。 However, in the hydrogen water production apparatus described in Patent Document 1, as described in Patent Document 1, the diameter of bubbles of hydrogen gas in the produced hydrogen water is limited to about 2 μm. As the diameter of hydrogen gas bubbles is smaller, the characteristics of the hydrogen water are improved, and further bubble size reduction is desired.
　本発明は前記事情に鑑みてなされたものであり、その目的とするところは、従来よりも直径の小さな気泡を含む液体を製造することのできる微小気泡生成装置、水素水製造装置及び水素水製造方法を提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to produce a micro-bubble generating apparatus, a hydrogen water producing apparatus, and a hydrogen water producing apparatus capable of producing a liquid containing bubbles having a smaller diameter than conventional ones. It is to provide a method.
　本発明によれば、一端側から他端側へ流体が流通する筒体と、前記筒体内における前記流体の流通方向へ延び、前記流体の通路の内壁をなす外周面を有する内側部材と、前記筒体における前記流体の流通方向へ延び、前記流体の通路の外壁をなし前記内側部材の前記外周面と対向する内周面を有する外側部材と、前記内側部材及び前記外側部材を前記流通方向を軸として相対的に回転させる回転部と、前記内側部材の前記外周面と、前記外側部材の前記内周面の少なくとも一方に、周方向に周期的に形成される凹凸部と、を備え、前記筒体の一端側から流入する気液混合流体を、微小気泡を含む液体として前記筒体の他端側から流出させる微小気泡生成装置が提供される。 According to the present invention, a cylindrical body through which fluid flows from one end side to the other end side, an inner member having an outer peripheral surface that extends in the flow direction of the fluid in the cylindrical body and forms an inner wall of the fluid passage, An outer member having an inner peripheral surface extending in the fluid flow direction in the cylinder and forming an outer wall of the fluid passage and facing the outer peripheral surface of the inner member; and the inner member and the outer member in the flow direction. A rotating portion that relatively rotates as an axis; and an uneven portion that is periodically formed in a circumferential direction on at least one of the outer peripheral surface of the inner member and the inner peripheral surface of the outer member, There is provided a microbubble generating device that causes a gas-liquid mixed fluid flowing from one end side of a cylindrical body to flow out from the other end side of the cylindrical body as a liquid containing microbubbles.
　この微小気泡生成装置によれば、筒体の流入口から気液混合流体が供給されると、気液混合流体は内側部材と外側部材により形成される流体通路へ流入する。ここで、流体通路は、内側部材と外側部材の少なくとも一方に周期的な凹凸部が形成されていることから、周方向について幅寸法が変化している。そして、回転部を駆動して内側部材と外側部材を相対的に回転させると凹凸部が周方向へ移動し、流体通路内の流体には周期的に圧縮及び開放の力が作用し、流体が周期的に収縮及び膨張される。このとき、気体が微小気泡となって液体中に含有されることとなる。これにより、筒体内の気液混合流体は、微小気泡を含む液体となり、筒体の流入口から流出する。 According to this microbubble generating device, when the gas-liquid mixed fluid is supplied from the inlet of the cylinder, the gas-liquid mixed fluid flows into the fluid passage formed by the inner member and the outer member. Here, since the fluid passage has a periodic uneven portion formed in at least one of the inner member and the outer member, the width dimension changes in the circumferential direction. Then, when the rotating portion is driven to relatively rotate the inner member and the outer member, the concavo-convex portion moves in the circumferential direction, and force of compression and release periodically acts on the fluid in the fluid passage, and the fluid Periodically contracts and expands. At this time, the gas becomes microbubbles and is contained in the liquid. Thereby, the gas-liquid mixed fluid in the cylinder becomes a liquid containing microbubbles and flows out from the inlet of the cylinder.

The bubble diameter can be further reduced.
　また、上記微小気泡生成装置において、前記ロータと一体的に設けられ、前記モータにより前記ロータとともに回転し、前記筒体内の前記流体の流通を促進するファンを備えてもよい。 The microbubble generator may include a fan that is provided integrally with the rotor and that rotates together with the rotor by the motor and promotes the flow of the fluid in the cylinder.
　この微小気泡生成装置によれば、ロータを駆動するモータによりファンが駆動するので、筒体内にファンを設けても駆動部品点数が増大することはない。 According to this microbubble generator, since the fan is driven by the motor that drives the rotor, the number of drive parts does not increase even if the fan is provided in the cylinder.

　電気分解装置は、陰極と陽極が配置される電解槽を有し、供給管を通じて供給された水の一部を電気分解する。電解槽にて水の一部が電気分解されると、陰極にて水素ガスが発生し、陽極にて酸素ガスが発生する。本実施形態においては、電解槽の内部には、板状の陰極と板状の陽極が間隔をおいて互い違いに配置されている。 The electrolyzer has an electrolytic cell in which a cathode and an anode are arranged, and electrolyzes a part of water supplied through a supply pipe. When part of the water is electrolyzed in the electrolytic cell, hydrogen gas is generated at the cathode and oxygen gas is generated at the anode. In the present embodiment, plate-like cathodes and plate-like anodes are alternately arranged at intervals inside the electrolytic cell.

　ここで、連結管３０へ流出する水には、気泡として水素ガスが含まれているので、水素水ということもできる。本明細書においては、水素ガスの気泡を含む水を「水素水」という。 Here, since the water flowing out to the connecting pipe 30 contains hydrogen gas as bubbles, it can also be referred to as hydrogen water. In this specification, water containing hydrogen gas bubbles is referred to as “hydrogen water”.
　微小気泡生成装置４０は、連結管３０から供給される水と水素ガスの混合流体から、当該水素ガスの微小な気泡が含まれる水素水を生成する。ここでいう微小とは、電気分解装置にて生成される水素水の水素ガスの気泡よりも小さいことをいう。具体的には、数ｎｍから数十ｎｍのレベルの気泡が生成可能である。本実施形態においては、微小気泡生成装置４０は、排出水槽６０の内側に配置され、微小気泡生成装置４０にて生成された水素水は、一旦、排出水槽６０内に貯留されてから、流出管５０を通じて排出される。 The micro-bubble generating device 40 generates hydrogen water containing micro bubbles of the hydrogen gas from the mixed fluid of water and hydrogen gas supplied from the connecting pipe 30. Here, the term “microscopic” means that it is smaller than hydrogen gas bubbles of hydrogen water produced by an electrolyzer. Specifically, bubbles having a level of several nanometers to several tens of nanometers can be generated. In the present embodiment, the microbubble generating device 40 is disposed inside the discharge water tank 60, and the hydrogen water generated by the microbubble generating device 40 is once stored in the discharge water tank 60 and then the outflow pipe. 50 is discharged.
　図２に示すように、微小気泡生成装置４０は、上下に延び一端側から他端側へ流体が流通する筒体４１と、筒体４１内にて上下方向へ延び流体の通路の内壁をなす外周面４２ａを有するロータ４２と、筒体４１内にて上下方向へ延び流体の通路の外壁をなす内周面４３ａを有するステータ４３と、ロータ４２を上下方向を軸として回転させるモータ４４と、を備えている。筒体４１の上端は蓋部材４５により、筒体４１の下端は底部材４６により、それぞれ閉塞され、筒体４１は外部と気密となっている。また、微小気泡生成装置４０は、ロータ４２と一体的に設けられ、モータ４４によりロータ４２とともに回転し、筒体４１内の前記流体の流通を促進するファン４７を備えている。 As shown in FIG. 2, the microbubble generator 40 includes a cylinder 41 that extends vertically and from which fluid flows from one end side to the other end side, and extends in the vertical direction within the cylinder 41 to form an inner wall of a fluid passage. A rotor 42 having an outer peripheral surface 42a, a stator 43 having an inner peripheral surface 43a extending in the vertical direction in the cylinder 41 and forming an outer wall of a fluid passage, and a motor 44 for rotating the rotor 42 about the vertical direction; It has.

　筒体４１は、円筒状に形成され、上部に混合流体が流入する流入口４１ａと、下部に水素水が流出する流出口４１ｂと、を有している。すなわち、本実施形態においては、筒体４０の上端側から下端側へ流体が流通する。流入口４１ａから流入した流体は、内側部材としてのロータ４２及び外側部材としてのステータ４３の間隙を通じ、流出口４１ｂまで流通する。本実施形態においては、流入口４１ａは、筒体４１上部に１箇所形成され、流出口４１ｂは、筒体４１下部に周方向に並んで複数箇所形成されている。 The cylindrical body 41 is formed in a cylindrical shape, and has an inflow port 41a into which a mixed fluid flows in an upper portion and an outflow port 41b from which hydrogen water flows out in a lower portion. That is, in the present embodiment, fluid flows from the upper end side of the cylindrical body 40 to the lower end side. The fluid flowing in from the inflow port 41a flows through the gap between the rotor 42 as the inner member and the stator 43 as the outer member to the outflow port 41b. In the present embodiment, the inflow port 41a is formed at one location on the upper portion of the cylinder 41, and the outflow ports 41b are formed at a plurality of locations along the circumferential direction at the lower portion of the cylinder 41.
　ロータ４２は、上下に延びるシャフト４４ａに連結され、シャフト４４ａはモータ４４の駆動により回転するようになっている。シャフト４４ａは、蓋部材４５を挿通し、底部材４６に回転自在に固定されている。また、シャフト４４ａには、ロータ４２の下方にてファン４７が固定されている。 The rotor 42 is connected to a shaft 44 a extending vertically, and the shaft 44 a is rotated by driving of the motor 44. The shaft 44a is inserted through the lid member 45 and is rotatably fixed to the bottom member 46. A fan 47 is fixed to the shaft 44a below the rotor 42.
　シャフト４４ａの上端は、カップリング４４ｂにより歯車機構４４ｃと接続されている。すなわち、モータ４４からの出力は、歯車機構４４ｃ及びカップリング４４ｂを介してシャフト４４ａに伝達される。カップリング４４ｂ、歯車機構４４ｃ及びモータ４４は、蓋部材４５に設けられるカバー４４ｄにより全体的に覆われている。 The upper end of the shaft 44a is connected to the gear mechanism 44c by a coupling 44b. That is, the output from the motor 44 is transmitted to the shaft 44a through the gear mechanism 44c and the coupling 44b. The coupling 44b, the gear mechanism 44c, and the motor 44 are entirely covered by a cover 44d provided on the lid member 45.
　図３に示すように、ロータ４２の外周面４２ａは、周方向に周期的に形成される凹凸部４２ｂが形成される。本実施形態においては、凹凸部４２ｂは、径方向外側へ突出する凸部４２ｃが周方向へ等間隔に６箇所形成され、径方向内側へ凹む凹部４２ｄが各凸部４２ｃの間に各凸部４２ｃと連続的に形成されている。 As shown in FIG. 3, the outer circumferential surface 42a of the rotor 42 is formed with uneven portions 42b that are periodically formed in the circumferential direction. In the present embodiment, the convex and concave portions 42b are formed with six convex portions 42c protruding outward in the radial direction at equal intervals in the circumferential direction, and concave portions 42d concave inward in the radial direction are provided between the convex portions 42c. 42c is formed continuously.
　図５に示すように、ステータ４３の内周面４３ａと対向する上下区間にわたって、凹凸部４２ｂが同一断面を呈している。すなわち、各凸部４２ｃは、上下へ延びる突条部ということもでき、各凹部４２ｄは、上下へ延びる溝部ということもできる。 As shown in FIG. 5, the concave and convex portion 42 b has the same cross section over the upper and lower sections facing the inner peripheral surface 43 a of the stator 43. That is, each convex part 42c can also be called a protrusion part extending up and down, and each concave part 42d can also be called a groove part extending up and down.
　また、ロータ４２は、凹凸部４２ｂの上端から上方へ向かって径方向内側へ傾斜する上端傾斜部４２ｅと、凹凸部４２ｂの下端から下方へ向かって径方向内側へ傾斜する下端傾斜部４２ｆと、を有している。上端傾斜部４２ｅと下端傾斜部４２ｆの近傍では、筒体４１内の流体の通路が大きくなり、凹凸部４２ｎの上側及び下側にて流体の流通が阻害されることはない。 The rotor 42 includes an upper end inclined portion 42e that is inclined radially inward from the upper end of the uneven portion 42b, and a lower end inclined portion 42f that is inclined radially inward from the lower end of the uneven portion 42b, have. In the vicinity of the upper end inclined portion 42e and the lower end inclined portion 42f, the fluid passage in the cylindrical body 41 becomes large, and the flow of the fluid is not hindered on the upper side and the lower side of the uneven portion 42n.
　図３に示すように、ステータ４３は、筒体４１の内面に固定され、内周面４３ａには周方向に周期的に形成される凹凸部４３ｂが形成される。本実施形態においては、凹凸部４３ｂは、径方向内側へ突出する凸部４３ｃが周方向へ等間隔に６箇所形成され、径方向外側へ凹む凹部４３ｄが各凸部４３ｃの間に各凸部４３ｃと連続的に形成されている。 As shown in FIG. 3, the stator 43 is fixed to the inner surface of the cylinder 41, and the inner peripheral surface 43a is formed with uneven portions 43b that are periodically formed in the circumferential direction. In the present embodiment, the concave and convex portions 43b are formed with six convex portions 43c protruding radially inward at equal intervals in the circumferential direction, and concave portions 43d recessed radially outward are provided between the convex portions 43c. 43c is formed continuously.
　図６に示すように、凹凸部４３ｂは、上下にわたって同一断面を呈している。すなわち、各凸部４３ｃは、上下へ延びる突条部ということもでき、各凹部４３ｄは、上下へ延びる溝部ということもできる。 As shown in FIG. 6, the concavo-convex portion 43b has the same cross section in the vertical direction. That is, each protrusion 43c can also be referred to as a protrusion extending vertically, and each recess 43d can also be referred to as a groove extending vertically.
　本実施形態においては、ロータ４２とステータ４３により形成される流体通路は、上下に６０ｍｍとなっており、最小の隙間は２ｍｍとなっている。そして、モータ４４を駆動してロータ４２を回転させると、最小の隙間の部分で流体に一時的に５０００気圧程度の圧力を加えることができる。この隙間は小さい方がよいが、２．５ｍｍ以下とすることにより、１５００気圧以上の圧力が流体に加わることが確認されている。 In the present embodiment, the fluid passage formed by the rotor 42 and the stator 43 is 60 mm in the vertical direction, and the minimum gap is 2 mm. Then, when the motor 44 is driven to rotate the rotor 42, a pressure of about 5000 atmospheres can be temporarily applied to the fluid at the minimum gap portion. Although it is preferable that the gap is small, it has been confirmed that a pressure of 1500 atm or more is applied to the fluid by setting the gap to 2.5 mm or less.
　図２に示すように、ファン４７は、シャフト４４ａと連結される円板状の平板部４７ａと、平板部４７ａ上に形成され径方向へ延びる複数の羽根４７ｂと、を有している。本実施形態においては、各羽根４７ａは、筒体４１の流出口４１ｂと同じ高さに形成されている。また、図４に示すように、各羽根４７ａは、平板部４７ａの径方向外側に形成されている。また、図７に示すように、ファン４７は、平板部４７ａの中心が厚く形成され、シャフト４４ａとの係合時にがたつかないようになっている。ファン４７がモータ４４の駆動により回転すると、筒体４１内の流体が流出口４１ｂへ向けて移動される。 As shown in FIG. 2, the fan 47 has a disk-shaped flat plate portion 47a connected to the shaft 44a, and a plurality of blades 47b formed on the flat plate portion 47a and extending in the radial direction. In the present embodiment, each blade 47 a is formed at the same height as the outlet 41 b of the cylindrical body 41. Moreover, as shown in FIG. 4, each blade | wing 47a is formed in the radial direction outer side of the flat plate part 47a. Further, as shown in FIG. 7, the fan 47 is formed so that the center of the flat plate portion 47a is thick and does not rattle when engaged with the shaft 44a. When the fan 47 is rotated by driving the motor 44, the fluid in the cylinder 41 is moved toward the outlet 41b.
　以上のように構成された水素水製造装置１の微小気泡生成装置４０によれば、筒体４１の流入口４１ａから気液混合流体が供給されると、気液混合流体はロータ４２とステータ４３により形成される流体通路へ流入する。ここで、流体通路は、ロータ４２とステータ４３に周期的な凹凸部４２ｂ，４３ｂがそれぞれ形成されていることから、周方向について幅寸法が変化している。そして、モータ４４を駆動してロータ４２をステータ４３に対して回転させると各凹凸部４２ｂ，４３ｂが相対的に周方向へ移動し、流体通路内の流体には周期的に圧縮及び開放の力が作用し、流体が周期的に収縮及び膨張される。このとき、水素ガスが微小気泡となって水の中に含有されることとなる。これにより、筒体４１内の水素ガスと水の混合流体は、水素ガスの微小気泡を含む水（水素水）となり、筒体４１の流出口４１ｂから流出する。流出する水素水には、１００ｎｍ以下の直径の気泡が含有されており、従来よりも直径の小さな気泡を含む水素水を製造することができる。 According to the micro-bubble generating device 40 of the hydrogen water producing apparatus 1 configured as described above, when the gas-liquid mixed fluid is supplied from the inlet 41a of the cylindrical body 41, the gas-liquid mixed fluid is converted into the rotor 42 and the stator 43. Flows into the fluid passage formed by Here, the width dimension of the fluid passage is changed in the circumferential direction because periodic uneven portions 42 b and 43 b are respectively formed in the rotor 42 and the stator 43. When the motor 44 is driven to rotate the rotor 42 with respect to the stator 43, the concave and convex portions 42b and 43b move relatively in the circumferential direction, and the force in the fluid in the fluid passage is periodically compressed and released. Acts and the fluid is periodically contracted and expanded. At this time, hydrogen gas becomes microbubbles and is contained in water. As a result, the mixed fluid of hydrogen gas and water in the cylinder 41 becomes water (hydrogen water) containing micro bubbles of hydrogen gas, and flows out from the outlet 41 b of the cylinder 41. The hydrogen water flowing out contains bubbles with a diameter of 100 nm or less, and hydrogen water containing bubbles with a smaller diameter than before can be produced.
　実際に、本実施形態の微小気泡生成装置４０を作成し、水素水を製造したところ、得られた水素水中の水素ガスの気泡の直径は２０ｎｍ以下であり、１ｃｃ当たり１５００万個以上の気泡が観測され、酸化還元電位は－８４０ｍＶであった。この水素水では、ナノレベルの気泡となった水素ガスが、水の隙間に入り込むため、長時間経過した後も水中に浮遊し続ける。従って、長時間経過し、水素ガスの浮力により、水と水素ガスが分離する水素水とは異なるものである。 Actually, when the microbubble generating device 40 of this embodiment was created and hydrogen water was produced, the diameter of the bubbles of hydrogen gas in the obtained hydrogen water was 20 nm or less, and 15 million or more bubbles per cc. Observed, the redox potential was -840 mV. In this hydrogen water, hydrogen gas that has become nano-level bubbles enters the gaps in the water, and therefore continues to float in the water even after a long time has passed. Therefore, it is different from the hydrogen water that has passed for a long time and separated from water and hydrogen gas due to the buoyancy of hydrogen gas.
　また、本実施形態においては、ロータ４２及びステータ４３の両方に凹凸部４２ｂ，４３ｂを形成したので、流体通路の周方向の幅寸法変化を大きくすることができる。これにより、圧縮時及び開放時に流体に加わる力を大きくすることができ、気泡の微小化に効果的である。 In the present embodiment, since the uneven portions 42b and 43b are formed in both the rotor 42 and the stator 43, the change in the width dimension in the circumferential direction of the fluid passage can be increased. Thereby, the force added to the fluid at the time of compression and opening can be increased, which is effective for miniaturization of bubbles.
　また、本実施形態の微小気泡生成装置４０によれば、筒体４１を円筒形状とし、ステータ４３を筒体４１に固定するとともにロータ４２を回転可能とし、ロータ４２がモータ４４により回転するようにしてので、装置４０の構成を比較的簡単にすることができる。また、ロータ４２を駆動するモータ４４によりファン４７が駆動するので、筒体４１内にファン４７を設けても駆動部品点数が増大することはない。 Further, according to the microbubble generating device 40 of the present embodiment, the cylinder 41 is cylindrical, the stator 43 is fixed to the cylinder 41, the rotor 42 is rotatable, and the rotor 42 is rotated by the motor 44. Thus, the configuration of the device 40 can be made relatively simple. In addition, since the fan 47 is driven by the motor 44 that drives the rotor 42, the number of drive parts does not increase even if the fan 47 is provided in the cylinder 41.
