Description

Hydrogen water manufacturing device, manufacturing method thereof and storage method

The present invention relates to a hydrogen water production apparatus, a method for producing the same, and a storage method, and more particularly to a hydrogen production apparatus, a method for producing the same, and a storage method for hydrogen water which is mixed with water under hydrogen pressure and dissolved in water.

Under the awareness of health, the hydrogen water in which hydrogen is dissolved is attracting attention. Hydrogen water enters the body and its active oxygen disappears due to its reducing power, which is considered to have an anti-aging effect. The hydrogen gas dissolved in the hydrogen water is taken up as a beverage water through the mouth, and is ingested through the skin by washing the face, bathing, or even the cosmetics.

Further, since hydrogen water has a reducing power, it also has a method of using a detergent as an electronic component. The oxide film covering the surface of the electronic component can be removed by washing the electronic component with hydrogen water.

The hydrogen water to be used in the present invention is a so-called "active hydrogen water" which dissolves atomic hydrogen (hydrogen radical or hydride ion) by dissolving hydrogen molecules in water.

A method of dissolving hydrogen molecules in water to produce hydrogen water is known as a hydrogen injection method in which hydrogen gas is sprayed into a water through a porous tube to be bubbled to dissolve hydrogen. (For example, refer to Japanese Patent Literatures 1, 2).

The hydrogen molecule is a gas at normal temperature and pressure, and its solubility in water is 1 atm (0.101 MPa) at 20 ° C (normal temperature. atmospheric pressure) is 1.62 ppm (1.62 mg in 1 liter of pure water), which is normal temperature. Saturated solubility at atmospheric pressure.

According to the Henry method, the solubility of gas is proportional to the pressure, so the dissolution rate of hydrogen to water is fast and the amount of dissolution increases. However, when it returns to normal pressure, the hydrogen dissolved in the water will degas and return to the saturated solubility at normal temperature and pressure.

Hydrogen water manufacturing equipment installed in general households, there are a wide variety of products available on the market, but they are all large-scale devices, and the price is also high. There will be problems with the need for larger-scale equipment for professional use in food and beverage outlets or beauty salons.

A method called solid ceramic method is a method for easily producing hydrogen water. In this method, only a powder of mixed metal magnesium such as cerium oxide (quartz) or calcium carbonate (coral calcium) is formed into a rod shape, and a container in which water is placed can form hydrogen water, but there is a lack of actual data and Lack of repetitive issues.

It is commercially available to replace the magnesium hydride or calcium hydride mixed with hydrogen bath to the metal magnesium described above.

Any one way is at room temperature. Under normal pressure, so of course at room temperature. The saturation concentration under normal pressure will of course fall, by means of very low concentrations.

In addition, the concentration of hydrogen contained in hydrogen water is only a very small amount of 1.6 ppm even at a saturated concentration, and hydrogen itself must not become too large a cost, but in the case of the existing method, depending on the method, but electrical or disposable Materials, etc., will cost several times to hundreds of times the cost of hydrogen itself.

There are also problems with preservation and transportation for the problem of hydrogen water. In other words, the hydrogen gas dissolved in the water is easily degassed, and it is considered that the hydrogen water in a saturated state is allowed to stand in an open state and reduced to a concentration of 1/10 over 2 hours (refer to Japanese Patent Laid-Open Publication No. 3).

According to a survey conducted by the weekly magazine, the dissolved hydrogen concentration of the hydrogen water charged into the PET bottle purchased by the online shopping was examined, and the dissolved hydrogen concentrations of the two brands examined were both 0 ppm. At the same time, the dissolved hydrogen concentration of the three types of hydrogen water filled in the aluminum can was measured in the range of 0.1 to 0.8 ppm. These hydrogen waters are produced at the factory by beverage water manufacturers. According to the label, the amount of hydrogen dissolved in water is close to that of the water during the production. Therefore, the hydrogen dissolved in the transportation and during storage disappears by 90% or more. Hydrogen water can also be purchased in supermarkets, supermarkets, pharmacies, etc. However, there is a problem that these sales channels including online shopping cannot purchase high-concentration hydrogen water.

The present invention relates to an apparatus for producing hydrogen water and a method of manufacturing the same.

1 and 2 are side views showing a manufacturing apparatus for producing hydrogen water of hydrogen water.

The manufacturing apparatus of the hydrogen water of the present invention has a container which is capable of sealing the water and a pressurizing means, and pressurizes the hydrogen gas in a gas state accommodated in the container together with water to a pressure of not more than 10 air pressure or less as a container. The hydrogen pressure inside, the pressure means is the pressure of hydrogen contained in the hydrogen storage container or the mechanical pressure for compressing the hydrogen by pumping, and the hydrogen storage container is connected with the container to supply hydrogen to the connecting tube of the container containing the water. It is also characterized by a mixing means for mixing the water in the vessel to bring the water into contact with the hydrogen.

Further, the method for producing a hydrogen water according to the present invention is characterized in that it has a container which is capable of hermetically accommodating water and a pressurizing means, and pressurizes a hydrogen gas in a state of being contained in a container together with water, and the pressurizing means is a pressure of hydrogen in a hydrogen storage container or a mechanical pressure for compressing hydrogen by pumping, having a hydrogen storage container connected to a container filled with water to supply hydrogen to a connecting pipe of the container, and the inside of the container is pressurized by means of pressure The hydrogen pressure is set to 1 atmosphere or more and less than 10 atmospheres, and the vessel or hydrogen gas is uniformly sprayed into the water to bring the water into contact with hydrogen to dissolve the hydrogen in the water.

The sealed container used in the present invention is a container that can accommodate water in the interior and can accommodate hydrogen gas of an atmospheric pressure or higher. The shape, size, and material of the sealed container are not particularly limited, but the container of the size of the hydrogen water in the drinking container can be held regardless of the plastic. Bottles or plastic bags, glass bottles, ceramic vessels, and metal containers are available.

Among them, in the case where a high pressure is formed in the container, it is also possible to use a screw cap that can be rotated and locked to maintain airtightness, and to form a group of plastic bottles, plastic bags, glass bottles, and metal bottles.

Plastics used in plastic bottles include polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, polystyrene, and polyvinyl acetate. (polyvinyl acetate), polytetrafluoroethylene, ABS resin, acrylonitrile styrene resin, acrylic resin, polyamide, nylon, poly Polyacetal, polycarbonate, modified polyphenylene ether, polyester, PBT polybutylene terephthalate, polyethylene terephthalate A thermoplastic resin such as PET polyethylene terephthalate. Among them, polyethylene, polypropylene, polyvinyl chloride, and polyethylene terephthalate can be utilized well because of their low cost and excellent strength. In particular, polyethylene terephthalate bottles, also known as PET bottles, have been widely used and can be utilized.

Plastics used in plastic bags include polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, polystyrene, and polyvinyl acetate. (polyvinyl acetate), polytetrafluoroethylene, ABS resin, acrylonitrile styrene resin, acrylic resin, polyamide, nylon, poly Polyacetal, polycarbonate, modified polyphenylene ether, polyester, PBT polybutylene terephthalate, polyethylene terephthalate A thermoplastic resin such as PET polyethylene terephthalate.

Among them, polyethylene, polypropylene, polyvinyl chloride, and polyethylene terephthalate can be utilized well because of their low cost and excellent strength. These plastic bags are preferably a multi-layered construction of a thin film of aluminum. The hydrogen gas degassing of the hydrogen water can be delayed by laminating the aluminum film.

The glass bottle for producing hydrogen water is not limited in shape, material or color tone as long as the bottle mouth can be sealed with a screw cap and a pressure of 10 MPa. Glass bottles for use as containers for wine or carbonated beverages can be used.

Metals used in metal bottles include aluminum, steel, titanium, and the like. Among them, aluminum and steel bottles are being circulated as beverage containers such as carbonated drinks or coffee, and are therefore readily available, and these beverage containers can be used well.

On the other hand, in the case of producing hydrogen water in a facility requiring a large-capacity hydrogen water such as a restaurant, a beauty salon, a bathhouse, or a hospital, it is necessary to manufacture a large-sized sealed container.

Examples of large-sized closed containers include milk delivery tubes, 50-gallon iron drums, and reaction tanks of various sizes. The shape is generally cylindrical, and the material is made of metal.

Metals used in large containers include iron, copper, aluminum, etc., but alloys such as stainless steel or brass may also be used. In addition, it is possible to use a metal which is applied to a glass lining process or a ruthenium coating, and even a metal which is subjected to electroplating or painting on the surface.

These containers can be supplied to a manufacturing apparatus for assembling hydrogen water by simple processing using a commercially available existing product.

The water contained in these containers can be used for beverage water, and is not particularly limited. It is soft water having a hardness of 0 to 100, medium-hard water having a hardness of 100 to 300, and hard water having a hardness of 300 or more. Further, it may be a beverage water containing an additive such as a juice or a milk component.

The amount of water contained in the container is preferably 50 to 80% of the container capacity in consideration of the contact efficiency between water and hydrogen. Below 50%, the amount of hydrogen water that can be completed in one operation is too small, and it is not efficient. When 80% or more, the contact area between water and hydrogen is extremely small during mixing, and there is a fear that time will be spent on the production of hydrogen water.

The method for producing hydrogen gas dissolved in hydrogen water of the present invention includes various methods, for example, (A) a method of adding hydrogen such as sulfuric acid to a metal such as iron to produce hydrogen, and (B) a method for producing hydrogen in aluminum (Al). a method of adding an amphoteric metal such as zinc (Zn), tin (Sn) or lead (Pb) to alkaline water, and (C) a method of adding water to a reducing agent such as calcium hydride, magnesium hydride or sodium borohydride, (D) A method of electrolyzing water, and the like.

Hydrogen produced by any of these methods can also be used as a raw material for hydrogen water, but compression is carried out by hydrogen obtained by the reaction of an industrially produced metal with an acid, or absorbed by a hydrogen adsorption alloy, and filled into a hydrogen storage container. Hydrogen is both easy to use and easy to use.

The hydrogen storage container comprises a compressed hydrogen storage gas cylinder for compressing and storing 1 to 35 MPa of hydrogen, a liquid hydrogen storage tank using an ultra-low temperature insulated container, a hydrogen adsorption alloy gas cylinder capable of storing hydrogen at normal temperature and normal pressure, and a high pressure container. A hybrid gas cylinder combined with storage by a hydrogen adsorption alloy. Any of the hydrogen storage tanks can be used as the hydrogen supply source of the present invention, but the price is advantageously stored by compressing the hydrogen storage cylinder, and the hydrogen can be operated at normal temperature and pressure based on the safety level. It is advantageous to adsorb the alloy gas cylinder.

The hydrogen storage container and the sealed container can be connected to each other by a pressure-resistant connecting pipe to supply hydrogen gas in the hydrogen storage container to the water in the closed container.

In the case of storing a gas cylinder using compressed hydrogen, it is preferred to add a pressure gauge and a pressure regulator as a group of regulators in the hydrogen cylinder. In the case where the sealed container is, for example, a PET bottle, since the hydrogen gas can be supplied under reduced pressure, the connecting tube connecting the hydrogen bottle and the sealed container can be made of a pressure-resistant flexible tube made of plastic or rubber, and the hydrogen bottle and the closed container can be maintained. Hydrogen water was produced by uniformly shaking and mixing in a state in which the connecting pipes were joined.

In the case of using a hydrogen adsorption alloy gas cylinder as a hydrogen storage container, in order to stably take out hydrogen gas, a heating device may be installed in the hydrogen adsorption gas cylinder. Further, a compressor for compressing hydrogen may be provided in a connecting pipe connecting the hydrogen storage container and the hermetic container. By providing a compressor, hydrogen gas of 1 to 10 atmospheres can be supplied when the pressure of the compressed hydrogen storage cylinder is lowered, and when the hydrogen supply from the hydrogen adsorption alloy cylinder is too slow.

Hydrogen adsorption alloys have developed a wide variety of adsorption alloys. Representative adsorbing alloys include AB5 type LaNi, AB type TiFe, Mg type Mg2Ni, and the like. In the present invention, any adsorbent alloy can be used if it is an adsorbing alloy that adsorbs hydrogen gas as needed.

In the case of using a hydrogen bottle, the hydrogen bottle and the sealed container may be connected by a pressure-resistant connecting tube. For example, in the case of producing hydrogen gas in a reaction tank, it is preferable to use a metal tube made of stainless steel or brass as the connecting tube. Further, a tube made of a synthetic resin of a polyolefin resin, a polyamide, or a polytetrafluoroethylene may be changed into a metal connecting tube.

In order to firmly connect the hydrogen storage container to the connecting pipe, the reaction tank and the connecting pipe, end connectors are attached to both ends of the connecting pipe.

On the other hand, for example, when the sealed container is a PET bottle, the connecting tube is a flexible connecting tube that is easy to remove, and has high convenience. In the case where a flexible connecting pipe is used, since the mixing can be uniformly performed while the connecting pipe is joined, hydrogen water can be produced while supplying hydrogen gas.

For example, in the case of using a PET bottle as a sealed container, it is necessary to have a connection portion in which a flexible tube connected from a hydrogen bottle is combined with a PET bottle. The connecting portion is a cylindrical protrusion extending outward from the center of the bottle cap of the PET bottle, and the front end thereof is an insertion port, and one end of the pressure-resistant tube is inserted to communicate with the hydrogen bottle.

An end connector for connecting to the connecting portion is attached to the end of the connecting tube. Preferably, the end connector attached to the end of the flexible tube is connected to the end connector provided at the connecting portion by screwing or fitting. The end connector attached to the end of the flexible tube is connected to the end connector provided at the connecting portion to form a strong connection against hydrogen pressure.

Preferably, a check valve is provided at the connecting portion. By providing the check valve, the pressure inside the container can be maintained even if the connecting pipe is removed from the connecting portion. Hydrogen water which dissolves hydrogen in water can be produced by uniformly shaking and mixing the hydrogen pressure in the vessel at a high pressure.

The type of the check valve includes a swing check valve having a hinged end of the valve, a lift check valve having a S-shaped flow path, and a circle using a spring force switch. A disc type check valve or the like, but any of these valves can be used as a check valve for the connecting portion. In addition, the super valve that performs the switching of the disc type check valve by the force of the rubber can be utilized for miniaturization.

The connecting portion may be provided with a double-pass cock between the front end and the cover portion instead of a check valve. The cock may be closed after filling with hydrogen, and the flexible tube is removed, and the bottle is shaken to uniformly mix water and hydrogen.

For example, in the case of using a PET bottle as a closed container, the bottle cap of the closed container is prepared. The cap of the invention is processed using a cap that is grouped with a bottle as a container. A hole is inserted through the connecting portion at the center of the top (or bottom) of the cap, and a part of the check valve that penetrates the check valve, that is, the connecting portion, is fixed by an adhesive. In order to improve the airtightness, a flange that adheres to the side portion of the bottle cap may be provided on the outer peripheral portion of the connecting portion. Of course, it can also be made into a bottle cap.

The cap having the connecting portion with the check valve and the cap having the connecting portion including the double-pass cock can also be integrally formed by extrusion molding together with the cap having the internally threaded groove.

For example, in the case where the closed container is a glass bottle or an aluminum can, the bottle cap of the closed container is generally made of aluminum. In this case as well, a hole is inserted into the center of the top (or bottom) of the cap to insert the connecting portion, and the hole is inserted into the connecting portion having the check valve to be fixed. In order to improve the airtightness, a flange that adheres to the side portion of the bottle cap may be provided on the outer peripheral portion of the connecting portion. Further, in order to ensure the tightness of the cap and the container, a gasket may be provided at the bottom of the cap.

For example, in the case where the closed container is a steel bottle, the bottle cap can be prepared in the same manner as the aluminum bottle.

The filling amount of hydrogen gas stored in the closed container is faster, and the faster the hydrogen gas is dissolved, the hydrogen water can be produced in a short time. However, for example, in the case of using a PET bottle, the pressure limit of the internal pressure of the container is At the pressure of 10 atmospheres, the filling pressure of hydrogen is 1 to 10 atmospheres (0.1 to 1 MPa), preferably 2 to 8 atmospheres (0.2 to 0.8 MPa), more preferably 3 to 5 atmospheres (0.3 to 0.5 MPa).

The method of bringing water into contact with hydrogen is considered to be: (A) a container sealed with hand-held water and hydrogen, a method of uniformly mixing by shaking the upper and lower or left and right movements of the wrist, and (B) fixing the closed container to a horizontal reciprocating vibration. , a method of uniformly shaking and mixing, (C) a method of placing a sealed container in an ultrasonic vibrator to impart ultrasonic vibration, (D) a method of stirring water by a stirring device, and (E) inserting a nozzle into water to inject a high-pressure hydrogen gas The method and (F) a method of spraying a mist-like water into a high-pressure hydrogen gas filled in a container.

In the case where the water is brought into contact with hydrogen by a hand-held bottle container, it is the easiest method to uniformly mix the upper and lower or left and right movements of the wrist of the item (A). Hydrogen water can be produced at any time and any place if there is a hydrogen storage container and a pressure-sensitive connecting pipe and a dedicated cap for the joint.

By mixing with water in a state where the pressure inside the container is high, the hydrogen can be dissolved in a saturated solution concentration of 1 atmosphere or more. When the pressure is returned to normal pressure, the excess dissolved hydrogen becomes a fine foam and is degassed, and becomes a normal atmospheric pressure. Dissolution concentration.

In the case where the hydrogen water in which the hydrogen gas has been stored is stored, the pressure inside the container is maintained at a high pressure, and the hydrogen gas is stored in a high concentration for a long period of time. In this period, the saturated hydrogen concentration can be supplied.

On the other hand, in the case of producing hydrogen water from a medium to large closed container, it is considered that: (B) a method of fixing the sealed container to a horizontally reciprocating vibrator, uniformly shaking the mixture, and (C) placing the sealed container a method of applying ultrasonic vibration to an ultrasonic vibrator, (D) a method of stirring water by a stirring device, (E) a method of inserting a nozzle into water to inject high-pressure hydrogen, and (F) spraying a mist-like water into the filling A variety of methods, such as a method of high-pressure hydrogen in a vessel.

In the case where hydrogen water is produced in a medium to large sealed container, hydrogen gas may be injected from a part of the high pressure near the bottom of the water contained in the sealed container. In this case, the finer the bubble of the injected hydrogen or the larger the number of bubbles, the wider the contact area of hydrogen and water, and the faster the hydrogen is dissolved into the water. In addition, since the water is stirred by the bubbles, the manufacturing efficiency is improved.

In another embodiment, for example, when a hydrogen water is produced from a medium-sized milk can, a magnet having a rod-shaped magnet is sealed in the inside of the can, and the other magnet is rotated from the outside of the container. Rotate the device, stir the water inside the milk can, and contact with hydrogen.

In another embodiment, for example, when hydrogen water is produced in a large reaction vessel, the agitator may be placed in the upper portion of the vessel to stir the water. At this time, the motor for rotating the stirring flap may be disposed on the outer upper portion of the container or in a space inside the container. Example 1

Embodiments of the present invention will be described in detail based on embodiments. The redox potential was measured by a portable ORR meter RM-30P manufactured by Japan East Asia DKK Co., Ltd.
