Description

Hydrogenation system and liquid container used in the system

The present invention relates to a system for adding hydrogen to a liquid by a simple technique, and a liquid container used in the system.

In recent years, the health effects of drinking hydrogen water have become a hot topic. In addition to anti-inflammatory and antioxidant effects, many other health effects such as diabetes, constipation, periodontal disease, and other health effects have been confirmed by drinking hydrogen water, and the number of drinkers is increasing as health consciousness increases.
In addition, it is thought that the health effect by drinking hydrogen water correlates with the intake amount and frequency of hydrogen. That is, if the concentration of hydrogen water is doubled, the same level of health effects can be expected by drinking half the amount of hydrogen water.

As an apparatus for producing hydrogen water, for example, there is one disclosed in Patent Document 1. This is a factory facility for producing hydrogen water by introducing hydrogen generated in the hydrogen generation section to a pressure tank and cannot be easily used at home or the like.

On the other hand, it has been proposed that a test tube (Spitz) filled with a hydrogen generating material is placed in a container such as a plastic bottle containing water, the cap with a check valve is closed, and hydrogen water is produced in the container. (For example, Patent Document 2). However, Spitz is made to be used exclusively for a specific volume of PET bottles. For example, Spitz used for a 500 ml PET bottle contains a hydrogen generating material in an amount corresponding thereto, and the amount of hydrogen generating material required varies depending on the capacity of the target PET bottle. Therefore, the following problems remain.
For example, when Spitz dedicated to a 500 ml PET bottle is used for a 300 ml PET bottle, the hydrogen concentration increases, but the pressure becomes excessive and exceeds the pressure resistance of the PET bottle. On the other hand, when used for a 1000 ml PET bottle, the hydrogen concentration is lower than the expected value. That is, it is necessary to prepare a dedicated spitz for each capacity of the PET bottle, which is inferior in versatility.

In addition, although the water purifier type hydrogen water manufacturing apparatus is disclosed by patent document 3, it is indispensable to connect this apparatus to the faucet which supplies tap water. In addition, since a hydrogen gas cylinder is used, there are many restrictions in use, such as the need to install a gas leak detector in accordance with the High Pressure Gas Safety Law.

JP 2013-22567 A Japanese Patent No. 4651479 Japanese Patent No. 5095020

The present invention was devised in view of the current state of the prior art, and its purpose is to add high-concentration hydrogen to a liquid regardless of the size of the container by a simple and versatile technique. It is to provide means.

Means and effects for solving the problem

The hydrogenation system of the present invention includes a “hydrogen gas generator that extracts hydrogen gas from water (preferably purified water) under pressure control” and a “hydrogen gas supply that supplies hydrogen gas generated by the hydrogen gas generator to the outside” ”And“ a liquid container that is open when connected to the hydrogen gas supply path and is connected to the hydrogen gas supply path by an opening / closing means that closes when the connection is disconnected and that can contain liquid therein ” With.
The “liquid” referred to here is typically water, tea, coffee, any other beverage, and an electrolyte solution (physiological saline solution, infusion solution containing an electrolyte, etc.) used for medical purposes.

In the present invention, using a hydrogen gas generator that extracts hydrogen gas from water, the hydrogen obtained therefrom is added to the liquid. That is, since no hydrogen gas cylinder is used, it is possible to easily add hydrogen to the liquid with a compact device that can be easily installed at home, office, other sports clubs, and the like.
In addition, the hydrogen gas generator used in the present invention can take out hydrogen gas under pressure control, and the pressure of the generated hydrogen gas can be set to about 0.2 to 0.5 MPa, for example. In that case, since it does not become 1 MPa or more, it does not correspond to the high-pressure gas referred to in the high-pressure gas safety law, and it is not necessary to install a gas leak detector compliant with the law.

In the present invention, a hydrogen gas generator that can control the pressure of the generated hydrogen gas is used. Therefore, according to Henry's law, a hydrogen addition amount corresponding to the adjusted gas pressure can be realized, so that high concentration hydrogen can be added in the same manner regardless of the size of the liquid container.
Henry's law is a law concerning the amount of gas that can be dissolved in a liquid. In short, the gas in contact with the liquid can be dissolved in the liquid in an amount proportional to the pressure. That is, the higher the hydrogen gas pressure is, the more hydrogen gas can be added.

Using the hydrogenation system of the present invention, a consumer can make a beverage with added hydrogen (for example, hydrogen water) on the spot when he / she wants to drink it. Alternatively, in a medical field, an electrolyte solution (physiological saline solution, infusion solution containing an electrolyte, etc.) can be made in a necessary amount when necessary.
Conventionally, hydrogen water produced in factories has been sold in plastic bottles, aluminum pouches and cans, but since hydrogen was released over time after hydrogen was added, there was dissatisfaction with the hydrogen concentration. According to the present invention, it is possible to drink freshly prepared hydrogen water on the spot, so that such dissatisfaction with insufficient concentration is eliminated.

In the present invention, hydrogen gas is extracted from “water” using a hydrogen gas generator, but the “water” to be used is preferably “purified water”. "Purified water" generally means "water" from which impurities have been removed by techniques such as distillation, filtration, and ion exchange. “Purified water” is available at a low price in the general market.
Once the hydrogenation system of the present invention is installed, it can be continuously used by replenishing water (preferably purified water) thereafter, and therefore has an advantage of low running costs.

The liquid container of the present invention is suitable for use in the above hydrogenation system, and includes “opening / closing means that opens when connected to an external hydrogen gas supply path and closes when the connection is disconnected”. The liquid can be stored inside.
The opening / closing means provided in the liquid container is preferably composed of one or both of a detachable plug and a socket, but a check valve or the like may be used.

1 is an external perspective view of a hydrogenation system according to an embodiment of the present invention. The block diagram which shows the internal mechanism about the hydrogen gas generator in FIG. The perspective view which expands and demonstrates the liquid container in FIG.

The present invention relates to adding hydrogen to a liquid such as a beverage or a medical electrolyte solution. In the following embodiment, an example of adding hydrogen to a beverage will be described. Hydrogen can be added to the medical electrolyte solution in the same manner.

<Example of hydrogen gas generator>
First, a hydrogen gas generator 10 used in the present invention will be described with reference to FIGS. In the present invention, a hydrogen gas generator that can take out hydrogen gas from the charged water (preferably purified water) under pressure control is used.
Such a hydrogen gas generator itself is generally known, and any hydrogen gas generator can be used in the present invention as long as it has such a function. One example will be described with reference to FIGS.

FIG. 1 shows the external appearance of the hydrogen gas generator 10, and FIG. 2 is a block diagram schematically showing its internal mechanism. The cap 11 is opened and purified water is poured into the water tank 12 in the apparatus. The amount of water in the tank can be confirmed from a window 18 provided on the apparatus wall surface.
Purified water is sent from the water tank 12 to the electrolysis cell 13 while the switch 17 is turned on and the electrolysis cell 13 is energized. On the anode side of the electrolytic cell 13, a chemical reaction represented by the following formula (1) occurs.
Formula (1): 2H ₂ O → O ₂ + 4H ⁺ + 4e ⁻
Part of the generated oxygen (O ₂ ) and water (H ₂ O) is returned to the water tank 12 from the anode side of the electrolysis cell 13.

On the other hand, a chemical reaction represented by the following formula (2) occurs on the cathode side of the electrolytic cell 13.
Formula (2): 4H ⁺ + 4e ⁻ → 2H ₂
Part of the generated hydrogen gas (2H ₂ ) and water (H ₂ O) is sent from the cathode side of the electrolysis cell 13 to the hydrogen separation tank 14. In the illustrated example, water is returned from the hydrogen separation tank 14 to the water tank 12. The hydrogen gas stored in the hydrogen separation tank 14 flows into an external hydrogen gas supply tube (hydrogen gas supply path) 30 through the connection portion 20.

A pressure sensor 15 and a pressure gauge 16 are provided in a flow path 19 from the hydrogen separation tank 14 to the connection portion 20 in the hydrogen gas generator 10, and the hydrogen gas pressure detected by the sensor is displayed on the pressure gauge 16. Is done. The pressure gauge 16 is arranged on the apparatus wall surface and can read the value from the outside.

The power supplied to the electrolysis cell 13 is controlled as follows so that the hydrogen gas pressure discharged to the outside from the connection portion 20 is kept constant. That is, the output of the DC power source 19 is controlled using the output from the pressure sensor 15 to keep the gas pressure at a constant value. The fixed value may be fixed, or may be changed by the user operating a lever or the like. In either case, it may be realized by a generally known method and is not a point of the present invention, and therefore will not be described in detail here.

In the hydrogenation system of the present invention, a hydrogen gas generator that generates hydrogen gas by using water is used without using a hydrogen gas cylinder. Therefore, the entire system can be made compact, and sports clubs and homes can be made compact. It can be installed in an office or other suitable place. The size of the hydrogen gas generator 10 can be designed to be, for example, about a width (37 cm), a depth (44 cm), a height (36 cm), or less, and therefore has a great advantage in terms of compactness.
In addition, since hydrogen gas can be taken out under pressure control, if the pressure of the generated hydrogen gas is set to, for example, about 0.2 to 0.5 MPa, it does not correspond to the high-pressure gas referred to in the high-pressure gas safety method, Therefore, it is not necessary to install a gas leak detector compliant with the law.

<< Liquid container 80 >>
Next, an example of the liquid container used in the hydrogenation system of the present invention will be described. Liquid container 80
Is connected to the hydrogen gas generator 10 via a coupler 50 (opening / closing means) located at the tip of a hydrogen gas supply tube (hydrogen gas supply path) 30. Although details will be described later, in FIG. 1A, the coupler 50 is disconnected, and in FIG. 1B, the coupler 50 is connected.

3 shows an enlarged detail of the liquid container 80 in FIG. The liquid container 80 contains a liquid to be hydrogenated, and the cap 81 is provided with a plug 56. The plug 56 is an element constituting the coupler 50 as shown in FIG. That is, the coupler 50 is constituted by a socket 55 and a plug 56, and when both are connected, the flow path is opened, and when separated, the flow path is closed. When the connected socket 55 and plug 56 are removed, the separation button 55 a provided on the side surface of the socket 55 is pressed.

In FIG. 3 (a), the tube 85 is extended from the plug 56 to the inside of the beverage. Therefore, hydrogen gas is directly supplied into the beverage, so that the hydrogenation efficiency is considered to be increased. However, since the hydrogen addition amount according to the gas pressure can be obtained according to Henry's law, the tube 85 can be omitted.

《Opening and closing means》
The liquid container 80 has an opening / closing means that opens when connected to the hydrogen gas supply tube (hydrogen gas supply path) 30 and closes when the connection is broken. The specific configuration is not limited to a specific one.
For example, in the liquid container 80 shown in FIG. 3A, the plug 56 is an opening / closing means. In addition, the socket 55 may be provided in the liquid container and this may be used as the opening / closing means, or the entire coupler 55 including the socket 55 and the plug 56 may be provided in the liquid container and used as the opening / closing means. As yet another example, a check valve may be employed as the opening / closing means.
In any case, the liquid container 80 is sealed by the cap 81 before being connected to the hydrogen gas supply tube 30, and when connected to the hydrogen gas supply tube 30, the hydrogen from the hydrogen gas supply tube 30 is Gas can enter the container.

<Modification>
In the illustrated example, the liquid container 80 includes a cap 81, and the cap includes an opening / closing means (plug 56). However, such a configuration is not necessarily required. In the present invention, the liquid container may be a container that can store a liquid therein, and may be provided with opening / closing means having the same function as described above at any position (for example, a container wall surface).

In the example shown in FIG. 1, the connecting portion 20 provided in the hydrogen gas generator 10 is also composed of the same coupler as the coupler 50 shown in FIG. However, since the coupler 50 as the opening / closing means exists on the liquid container 80 side, the connecting portion 20 may be formed of a normal joint member.
When the coupler 50 is used as the connection part 20, the tube 30 may be omitted and the liquid container 80 may be directly connected to the connection part 20. In that case, the hydrogen gas generated in the hydrogen gas generator 10 is supplied into the liquid container 80 from the flow path 19 (hydrogen gas supply path) through the connection part 20 as an opening / closing means. The connection unit 20 is not limited to the upper surface of the apparatus as illustrated, and can be disposed at any convenient position such as the front surface or the side surface.

<< Usage example of the hydrogenation system 10 >>
With reference to FIG. 1, the usage example of the hydrogenation system 10 is demonstrated. First, as shown in FIG. 1A, with the coupler 50 disconnected, the switch 17 is turned on, and the gas pressure generated in the hydrogen gas generator 10 has a desired value (for example, 0.2 to 0.00). 5 MPa). The gas pressure can be read with a pressure gauge 16 provided on the apparatus wall surface.

When the gas pressure reaches a desired value, the socket 55 provided at the tip of the hydrogen gas supply tube 30 is connected to the plug 56 provided in the cap 81 of the liquid container 80 as shown in FIG. As a result, hydrogen gas is injected into the liquid container 80 at a desired gas pressure.
Since hydrogen gas is injected into the container instantly, the socket 55 is removed thereafter. As described above, since the flow path is closed simultaneously with the removal of the socket 55, the container is sealed in a pressurized state. The consumer can shake the container to dissolve the hydrogen gas in the liquid and drink it.

The amount of dissolved hydrogen follows Henry's law. For example, if the gas pressure is 0.5 MPa, a theoretical hydrogen concentration of 8 ppm can be realized.
At normal temperature and normal pressure, only a hydrogen concentration of 1.6 ppm or less can be realized according to Henry's law. In the present invention, hydrogen gas generated under pressure control using the hydrogen gas generator 10 is contained in a liquid container. Therefore, it is possible to add hydrogen at a high concentration by controlling the gas pressure at the time of injection.

Also, since the amount of hydrogen added can be controlled by the gas pressure, it is possible to add hydrogen at a desired concentration regardless of the size of the liquid container. If a liquid container of a size that can be consumed at a time (for example, 150 to 200 ml) is used, it is possible to drink up all of the beverage with hydrogen added on the spot. Conventionally, hydrogen water produced in factories has been sold in plastic bottles, aluminum pouches and cans, but since hydrogen was released over time after hydrogen was added, there was dissatisfaction with the hydrogen concentration. According to the present invention, such dissatisfaction can be completely eliminated.

As described above, the hydrogen gas pressure may be fixed as a value inherent to the hydrogen gas generator 10, or may be changed by the user operating a lever or the like.

In the illustrated example, one system of hydrogen gas supply tubes 30 is provided for the hydrogen gas generator 10, but as another example, if two or more systems of hydrogen gas supply tubes 30 are provided, two or more liquid containers are provided. Hydrogen gas can be supplied simultaneously in parallel with 80. When importance is attached to the compactness of the apparatus, the hydrogen gas supply tube 30 is preferably a single system.
One hydrogen gas supply tube may be branched into two or three or more on the way. When such a plurality of systems are used, for example, it is possible to supply hydrogen gas simultaneously to containers of different sizes, or to supply hydrogen gas simultaneously to different liquids.
