本発明は、液体中においてオゾンを含む微細な気泡を発生させ、オゾンを含む液体を製造する製造装置の技術に関する。   The present invention relates to a technique of a manufacturing apparatus for producing a liquid containing ozone by generating fine bubbles containing ozone in the liquid.

近年、液中において気泡のサイズ(直径)が数百nm〜数十μmの超微細気泡を使用する技術が注目されている。前記超微細気泡は、表面積が非常に大きい特性及び自己加圧効果などの物理化学的な特性を有しており、その特性を生かして、魚介類の養殖、植物の栽培、食物の洗浄・殺菌、及び排水の脱色等に使用する技術が開発されている。   In recent years, attention has been focused on a technique using ultrafine bubbles having a bubble size (diameter) of several hundred nm to several tens of μm in a liquid. The ultrafine bubbles have a very large surface area and physicochemical properties such as a self-pressurizing effect. Taking advantage of these properties, fish culture, plant cultivation, food washing and sterilization And technology used for decolorization of waste water has been developed.

従来は、オゾンを含む液体の製造装置は、水銀灯やハロゲン灯による短い波長の紫外線照射や、無声放電などによりオゾンを発生させている。ここで、短い波長の紫外線とは185nmの波長を含む紫外線である。例えば、紫外線照射によるオゾンの発生においては、紫外線を発生させる水銀灯やハロゲン灯などの光源が必要であり、この光源はオゾン発生時に高熱となる。オゾンの製造工程において周囲の温度が高温になると、製造効率が落ちるため、光源の周囲を水等によって冷却する必要がある。
また、液体が水である場合、オゾンが水中で分解される過程においては活性酸素の一つであるヒドロキシラジカルが発生し酸化剤として働く。そこで、ヒドロキシラジカルの発生量を向上させることで酸化作用を強化することが望まれていた。
Conventionally, an apparatus for producing a liquid containing ozone has generated ozone by irradiation with a short wavelength ultraviolet ray by a mercury lamp or a halogen lamp, silent discharge, or the like. Here, the short wavelength ultraviolet light is ultraviolet light having a wavelength of 185 nm. For example, in the generation of ozone by ultraviolet irradiation, a light source such as a mercury lamp or a halogen lamp that generates ultraviolet light is required, and this light source becomes hot when ozone is generated. When the ambient temperature becomes high in the ozone production process, the production efficiency is lowered. Therefore, it is necessary to cool the periphery of the light source with water or the like.
Further, when the liquid is water, in the process where ozone is decomposed in water, hydroxy radicals, which are one of active oxygens, are generated and act as an oxidizing agent. Therefore, it has been desired to enhance the oxidation action by improving the amount of hydroxy radicals generated.

そこで、本発明はかかる課題に鑑み、オゾン発生時の熱を効率的に放熱することができ、オゾンを含む液体の酸化作用を向上させることができるオゾンを含む液体の製造装置を提供する。   Then, in view of this subject, this invention provides the manufacturing apparatus of the liquid containing ozone which can thermally radiate the heat | fever at the time of ozone generation | occurrence | production, and can improve the oxidation effect | action of the liquid containing ozone.

Here, the ultrafine bubbles mean bubbles having a size (diameter) of several hundred nm to several tens of μm. Moreover, ozone is contained in the ultrafine bubble which concerns on this embodiment. Ozone is a substance having a high oxidizing power, and has effects such as sterilization, decolorization, deodorization, and removal of organic substances in addition to an oxidizing action. In addition, by making ozone into ultrafine bubbles, unlike ordinary bubbles, it has a very large surface area and chemical properties such as a self-pressurizing effect, so ozone can be immersed in water for a longer time. Can exist.
Ozone water is used for aquaculture, plant cultivation, food cleaning and sterilization, and drainage decolorization.
In the present embodiment, ozone water is given as an example of a liquid containing ozone, but the present invention is not limited to this. For example, ozone can be mixed into skin lotion or seawater.

オゾン水製造装置1は、紫外線を照射する紫外線照射灯2と、紫外線照射灯2を内部に格納する第一の筒体3と、第一の筒体3を内部に格納する第二の筒体4と、紫外線照射灯2、第一の筒体3及び第二の筒体4の両端を密閉しつつ支持する壁体5と、第一の筒体3の外壁と第二の筒体4の内壁との間に液体通路6と、第一の筒体3の内部に気体を圧縮して送る気体圧送手段であるポンプ7と、第一の筒体3の内部に送られた気体に紫外線照射灯2によって紫外線を照射することで発生したオゾンを用いて液体中にオゾンを含む超微細気泡を発生させる超微細気泡発生装置10と、を備える。   The ozone water production apparatus 1 includes an ultraviolet irradiation lamp 2 that irradiates ultraviolet rays, a first cylinder 3 that stores the ultraviolet irradiation lamp 2 therein, and a second cylinder that stores the first cylinder 3 therein. 4, an ultraviolet irradiation lamp 2, a wall body 5 that supports both ends of the first cylinder body 3 and the second cylinder body 4 while being sealed, an outer wall of the first cylinder body 3, and a second cylinder body 4.

紫外線照射灯2は、圧送された気体へ紫外線を照射してオゾンを発生させる部材である。
紫外線照射灯2は、オゾンに対する耐性を備えている。また、紫外線照射灯2は、第一の筒体3の内部に配置されており、両端が壁体5・5によって支持されている。また、紫外線照射灯2は、図示せぬ安定器を介して図示せぬ電源に接続されている。
The ultraviolet irradiation lamp 2 is a member that generates ozone by irradiating ultraviolet rays to a pumped gas.

Further, the ultraviolet irradiation lamp 2 is disposed inside the first cylindrical body 3, and both ends thereof are supported by the wall bodies 5. The ultraviolet irradiation lamp 2 is connected to a power source (not shown) through a ballast (not shown).

第一の筒体3は、円筒状の部材であり、その内側に紫外線照射灯2を格納している。第一の筒体3は、石英によって形成されている。石英は、耐熱性が高く、紫外線を透過し、オゾンに対する耐腐食性も高い。このため、紫外線照射灯2からの熱に耐え、紫外線照射灯2から照射される紫外線を第一の筒体3の外側に透過させることができる。また、内部で発生したオゾンによる腐食も発生し難い。第一の筒体3の両端は、壁体5・5によって支持されている。   The 1st cylinder 3 is a cylindrical member, and stores the ultraviolet irradiation lamp 2 in the inner side. The first cylinder 3 is made of quartz. Quartz has high heat resistance, transmits ultraviolet light, and has high corrosion resistance to ozone. For this reason, the heat from the ultraviolet irradiation lamp 2 can be withstood, and the ultraviolet light irradiated from the ultraviolet irradiation lamp 2 can be transmitted to the outside of the first cylinder 3. Further, corrosion due to ozone generated inside is hardly generated. Both ends of the first cylinder 3 are supported by wall bodies 5.

The 2nd cylinder 4 is formed with the metal, and is formed with SUS316L which is a typical steel type of austenitic stainless steel in this embodiment. In addition, a reflective surface 4 a that has been subjected to a mirror finish is formed on the inner peripheral surface of the second cylindrical body 4. Thereby, the ultraviolet rays that have reached the inner peripheral surface can be reflected again into the second cylindrical body 4. Both ends of the second cylinder 4 are supported by wall bodies 5.
The second cylinder 4 is not limited to metal as long as it is a material that reflects ultraviolet rays into the second cylinder 4. For example, the second cylinder 4 is made of quartz, It is also possible to form a reflecting surface by depositing aluminum on the peripheral surface.

壁体5・5は、紫外線照射灯2、第一の筒体3及び第二の筒体4の両端を密閉しつつ支持する部材であり、円形の部材で構成されている。一方の壁体5には、気体圧入用孔5aと、オゾン水排出用孔5bと、が設けられており、他方の壁体5には、オゾン水流入用孔5cと、オゾン排出用孔5dと、が設けられている。気体圧入用孔5aおよびオゾン排出用孔5dは、第一の筒体3の内部と連通している。また、オゾン水排出用孔5b及びオゾン水流入用孔5cは、第二の筒体4の内周面と第一の筒体3の外周面とによって囲まれた液体通路6と連通している。   The wall bodies 5 and 5 are members that support the ultraviolet irradiation lamp 2, the first cylindrical body 3, and the second cylindrical body 4 while sealing the both ends, and are configured by circular members. One wall body 5 is provided with a gas injection hole 5a and an ozone water discharge hole 5b, and the other wall body 5 is provided with an ozone water inflow hole 5c and an ozone discharge hole 5d. And are provided. The gas press-fitting hole 5 a and the ozone discharge hole 5 d communicate with the inside of the first cylinder 3. Further, the ozone water discharge hole 5 b and the ozone water inflow hole 5 c communicate with the liquid passage 6 surrounded by the inner peripheral surface of the second cylinder 4 and the outer peripheral surface of the first cylinder 3. .

液体通路6は、オゾン水を通すための通路であり、第二の筒体4の内周面と第一の筒体3の外周面とによって囲まれている。液体通路6の上流側には、オゾン水流入用孔5cが設けられており、液体通路6の下流側には、オゾン水排出用孔5bが設けられている。   The liquid passage 6 is a passage through which ozone water passes, and is surrounded by the inner peripheral surface of the second cylinder 4 and the outer peripheral surface of the first cylinder 3. An ozone water inflow hole 5 c is provided on the upstream side of the liquid passage 6, and an ozone water discharge hole 5 b is provided on the downstream side of the liquid passage 6.

ポンプ7は、第一の筒体3の内部に気体を圧縮して送る装置であり、気体圧入用孔5aと連結している。ポンプ7によって送られる気体は、酸素を含む気体であり、例えば空気である。また、圧送される気体に、水素や窒素などを含ませることも可能である。   The pump 7 is a device that compresses and sends gas into the first cylindrical body 3 and is connected to the gas press-fitting hole 5a. The gas sent by the pump 7 is a gas containing oxygen, for example, air. In addition, hydrogen or nitrogen may be included in the gas to be pumped.

超微細気泡発生装置10は、液体中にオゾンを含む超微細気泡を発生させる装置である。
超微細気泡発生装置10は、図1及び図2に示すように、液体を圧送する液体圧送手段である液体噴射ポンプ11と、グラファイトと非金属との複合体であって多孔質である高密度複合体で形成された気泡発生媒体12と、を備える。
The ultrafine bubble generating device 10 is a device that generates ultrafine bubbles containing ozone in a liquid.
As shown in FIGS. 1 and 2, the ultrafine bubble generating device 10 is a high-density liquid injection pump 11 that is a liquid pumping means for pumping a liquid, a composite of graphite and nonmetal, and porous. A bubble generating medium 12 formed of a composite.

液体噴射ポンプ11は、液体を圧送することで液流を作成する装置である。液体噴射ポンプ11によって作成された液流は、気泡発生媒体12の周囲を移動する。   The liquid jet pump 11 is a device that creates a liquid flow by pumping liquid. The liquid flow created by the liquid jet pump 11 moves around the bubble generating medium 12.

気泡発生媒体12は、グラファイトと非金属との複合体であって多孔質である高密度複合体で形成されている。グラファイトと非金属との複合体とは、少なくとも、グラファイトと、セラミックス等の非金属とを含む材料で形成された複合体であり、他にガラスや金属等を含む素材であってもよい。含まれる金属は、例えば、オーステナイト系ステンレスの代表的な鋼種であるSUS316Lである。
また、多孔質とは、直径数百nm〜数十μmの無数の孔12b(図3参照)を有する性質を意味し、多孔質である高密度複合体は、通気性を備えるが、透水性は備えない。
高密度複合体は、熱伝導効率が高い素材であり、高密度複合体を介して効率よく熱交換を行うことができる。また、高密度複合体は、オゾンに対する耐腐食性を備えている。また、高密度複合体は、導電性を備えている。
The bubble generating medium 12 is a composite of graphite and nonmetal and is formed of a porous high density composite. The composite of graphite and nonmetal is a composite formed of a material containing at least graphite and a nonmetal such as ceramics, and may be a material containing glass or metal. The metal contained is, for example, SUS316L, which is a typical steel type of austenitic stainless steel.
Moreover, the porous means a property having innumerable pores 12b (see FIG. 3) having a diameter of several hundred nm to several tens of μm, and the porous high-density composite has air permeability, Will not prepare.
The high-density composite is a material having high heat conduction efficiency, and heat exchange can be efficiently performed through the high-density composite. Moreover, the high-density composite has corrosion resistance against ozone. In addition, the high-density composite has conductivity.

気泡発生媒体12は、内部に空間(内部空間12a)を設けた立体状に形成されており、本実施形態においては、直方体状に形成されている。また、内部空間12aとは、第一の筒体3において生成されたオゾンを圧入するための空間であり、その形状は限定するものではなく、例えば、長手方向へ延伸した一つの大きな空洞で構成することも可能である。ポンプ7から圧送されたオゾンは、図3に示すように、孔12bから液体中へ放出される構造となっている。すなわち、ポンプ7から圧送された気体のガス圧で、超微細気泡が孔12bから液体中へ放出されるものである。ガス圧は、周囲の水圧よりも高く設定されており、内部空間12aは陽圧となるように構成されている。   The bubble generating medium 12 is formed in a three-dimensional shape having a space (internal space 12a) therein, and is formed in a rectangular parallelepiped shape in the present embodiment. The internal space 12a is a space for press-fitting ozone generated in the first cylinder 3, and the shape thereof is not limited. For example, the internal space 12a is composed of one large cavity extending in the longitudinal direction. It is also possible to do. As shown in FIG. 3, the ozone pumped from the pump 7 has a structure that is discharged from the hole 12b into the liquid. That is, the ultrafine bubbles are discharged from the holes 12b into the liquid by the gas pressure of the gas pumped from the pump 7. The gas pressure is set higher than the surrounding water pressure, and the internal space 12a is configured to be a positive pressure.

次に、本実施形態に係るオゾン水製造装置1を用いたオゾン水の製造方法について説明する。
まず、ポンプ7によって空気が気体圧入用孔5aから第一の筒体3の内部へと圧送される。この際空気の圧力は、具体的には大気圧(約0.1MPa)よりも高い0.2MPaとなるように構成されている。これにより空気は加圧された状態で第一の筒体3の内部に流入する。
加圧された空気中の酸素は、第一の筒体3内部において紫外線照射灯2によって照射された紫外線によってオゾンとなる。ここで、空気が加圧された状態で、紫外線照射によるオゾン発生過程が行われるため、オゾンから酸素への逆反応が発生し難くなる。
Next, the manufacturing method of the ozone water using the ozone water manufacturing apparatus 1 which concerns on this embodiment is demonstrated.
First, air is pumped from the gas press-fitting hole 5 a into the first cylinder 3 by the pump 7. At this time, the air pressure is specifically configured to be 0.2 MPa, which is higher than atmospheric pressure (about 0.1 MPa). Thereby, air flows into the inside of the 1st cylinder 3 in the state pressurized.
The oxygen in the pressurized air becomes ozone by the ultraviolet rays irradiated by the ultraviolet irradiation lamp 2 inside the first cylindrical body 3. Here, since the ozone generation process by ultraviolet irradiation is performed in a state where air is pressurized, the reverse reaction from ozone to oxygen hardly occurs.

第一の筒体3内部で発生したオゾンは、オゾン排出用孔5dから排出され、超微細気泡発生装置10の気泡発生媒体12の内部空間12aへと流入する。このときオゾンの圧力の方が外部の液圧よりも高い陽圧状態であるので、内部空間12aには液体が流入せず、気体のみが充填されている。   The ozone generated inside the first cylinder 3 is discharged from the ozone discharge hole 5d and flows into the internal space 12a of the bubble generating medium 12 of the ultrafine bubble generating device 10. At this time, since the ozone pressure is in a positive pressure state higher than the external fluid pressure, the liquid does not flow into the internal space 12a, and only the gas is filled.

内部空間12aに流入したオゾンは、孔12bを通って、超微細気泡となって液体中へと放出される。このように放出されたオゾンを含む超微細気泡は、サイズ(直径)が数百nm〜数十μmの気泡である。このとき、液体噴射ポンプ11によって圧送された液体が気泡発生媒体12の周囲を移動することにより、超微細気泡は気泡発生媒体12の表面から離間しやすくなる。   The ozone flowing into the internal space 12a passes through the holes 12b and becomes ultrafine bubbles and is released into the liquid. The ultrafine bubbles containing ozone thus released are bubbles having a size (diameter) of several hundred nm to several tens of μm. At this time, the liquid pumped by the liquid jet pump 11 moves around the bubble generating medium 12, so that the ultrafine bubbles are easily separated from the surface of the bubble generating medium 12.

オゾンを含む超微細気泡が混入された水であるオゾン水は、オゾン水流入用孔5cから液体通路6へと流入する。液体通路6内のオゾン水は、紫外線照射灯2から発生する熱を吸収し、紫外線照射灯2の周囲の雰囲気および第一の筒体3を冷却する。オゾン水は、オゾンが超微細気泡の状態で含まれているため、気泡の表面積が大きくなり、熱伝導率が高くなる。このため、紫外線照射灯2の周囲の雰囲気および第一の筒体3の冷却効果が普通の水よりも高くなる。   Ozone water, which is water mixed with ultrafine bubbles containing ozone, flows into the liquid passage 6 from the ozone water inflow hole 5c. The ozone water in the liquid passage 6 absorbs heat generated from the ultraviolet irradiation lamp 2 and cools the atmosphere around the ultraviolet irradiation lamp 2 and the first cylinder 3. Since ozone water contains ozone in the form of ultrafine bubbles, the surface area of the bubbles is increased and the thermal conductivity is increased. For this reason, the cooling effect of the atmosphere around the ultraviolet irradiation lamp 2 and the first cylinder 3 is higher than that of ordinary water.

液体通路6内のオゾン水には、第一の筒体3を透過した紫外線が照射される。また第二の筒体4内面に反射面4aが形成されているため、反射面4aによって反射した紫外線が再びオゾン水に照射される。紫外線の照射により、オゾン水の中にヒドロキシラジカルが発生し易くなる。このため、ヒドロキシラジカルの発生量が向上して酸化作用が強化される。   The ozone water in the liquid passage 6 is irradiated with ultraviolet rays that have passed through the first cylindrical body 3. Moreover, since the reflective surface 4a is formed in the 2nd cylinder 4 inner surface, the ultraviolet-ray reflected by the reflective surface 4a is again irradiated to ozone water. Irradiation with ultraviolet rays facilitates the generation of hydroxy radicals in ozone water. For this reason, the generation amount of hydroxy radicals is improved and the oxidation action is enhanced.

ヒドロキシラジカルを多く含むオゾン水は、酸化作用の他、殺菌・脱色・脱臭・有機物の除去等の作用を奏することができる。例えば、食物の洗浄・殺菌、魚介類の養殖、植物の栽培等に使用することができる。
また、化粧品に用いる液体内で、超微細気泡発生装置10を用いた場合には、化粧品に用いる液体内にオゾンを含む超微細気泡が存在することで、オゾンの酸化作用を用いた肌の角質除去効果を奏することができる。
Ozone water containing a large amount of hydroxy radicals can exhibit sterilization, decolorization, deodorization, removal of organic substances, and the like in addition to oxidation. For example, it can be used for washing and sterilizing food, aquaculture, plant cultivation, and the like.
In addition, when the ultrafine bubble generating device 10 is used in the liquid used for cosmetics, the superficial bubbles containing ozone are present in the liquid used for cosmetics, so that the horny skin of the skin using the oxidizing action of ozone. A removal effect can be achieved.
