Description

  The present invention relates to a gas dissolving device, and more particularly to a gas dissolving device that can dissolve a gas in a liquid in a supersaturated state, stably maintain the supersaturated state, and can be easily attached to a water server or the like.

  In recent years, soft drinks and the like in which beverages such as water and tea are filled with gas such as carbon dioxide and hydrogen have been sold. In this way, by ingesting a gas filled in a liquid, it is possible to easily take into the human body what was difficult to take into the human body if the gas remains as it is. It is easy to demonstrate.

  For example, soft drinks such as water and tea filled with hydrogen gas are sold. This is intended to reduce active oxygen present in the human body by ingesting hydrogen gas filled in a liquid.

  Active oxygen, on the other hand, plays an important role in creating ATP (adenosine triphosphate) in the citric acid cycle, and is also essential for life support and also plays a role in eliminating foreign substances that have entered the body. Is known. In addition, active oxygen that has not been used in in vivo reactions or the like is usually decomposed by enzymes present in cells. However, not all active oxygen is decomposed by the enzyme, and surplus active oxygen is present without being decomposed. As a result, cells are damaged by surplus active oxygen, causing diseases such as cancer and lifestyle-related diseases, and aging, and eliminating surplus active oxygen is required for health maintenance.

  Therefore, in recent years, hydrogen has been used as a substance that eliminates such surplus active oxygen. This is because hydrogen has a very low molecular weight and is easily absorbed into the body, and further changes to water when it reacts with active oxygen, and has high safety reasons. Also, among the many active oxygens, only hydroxy radicals are selected and reduced, and the active oxygen useful for the body is not affected.

It is sectional drawing which shows an example of the gas dissolving apparatus of this invention. It is a figure which shows an example of use of the gas dissolving apparatus of this invention.

Hereinafter, the gas dissolving apparatus of the present invention will be described in detail.
FIG. 1 is a cross-sectional view showing an example of a gas dissolving apparatus of the present invention. In the figure, 1 is a gas dissolution apparatus, 2 is a gas generation mechanism, 3 is a pressurized gas dissolution mechanism, 4 is a dissolution mechanism, and 5 is a pressure-lowering mechanism. The gas dissolving apparatus 1 includes a gas generating mechanism 2 that generates gas, a pressurized gas dissolving mechanism 3 that pressurizes and dissolves the gas in a liquid, and a dissolving mechanism 4 that dissolves the liquid dissolving the gas. And a pressure-lowering mechanism 5 that lowers the pressure by flowing the liquid through the narrow tube. The liquid in which the gas is supersaturated and dissolved flows down in the thin tube and is depressurized, so that the gas can be dissolved in the liquid in a supersaturated state, and the supersaturated state can be maintained stably. Here, “supersaturation” means that the solubility of a gas in a liquid varies depending on the temperature, but the amount of gas dissolved in a liquid at a certain temperature A (° C.) is more than the solubility at that temperature A (° C.). Indicates the state.

  In FIG. 1, the gas generation mechanism 2 includes a hydrogen generation mechanism 21 and further includes an ion exchange mechanism 22. Furthermore, the hydrogen generation mechanism 21 generates hydrogen by electrolysis. The ion exchange mechanism 22 performs ion exchange using an ion exchange resin or the like.

  In FIG. 1, water is used as the liquid this time. Water is sucked from the liquid suction port 7 and sucked into the pressurization type gas dissolution mechanism 3 via the suction port 8 of the pressurization type gas dissolution mechanism 3, and then water is discharged from the discharge port 9 of the pressurization type gas dissolution mechanism 3. The discharged water is subjected to ion exchange by the ion exchange mechanism 22 and then sent to the hydrogen generation mechanism 21 via the hydrogen generation mechanism inlet 23. In the hydrogen generation mechanism 21, hydrogen is generated by electrolysis using ion-exchanged water and is sent to the suction port 8 of the pressurized gas dissolution mechanism through the hydrogen supply pipe 24. Further, oxygen generated by the electrolysis is discharged out of the gas dissolving apparatus 1 through the oxygen discharge port 25.

  Hydrogen generated by the electrolysis is sent to the suction port 8 of the pressurized gas dissolving mechanism, and is pressurized and dissolved in the water sucked from the liquid suction port 7 by being pressurized by the pressurized gas dissolving mechanism 3. The water in which hydrogen is dissolved under pressure is discharged from the discharge port 9 of the pressurized gas dissolving mechanism 3 and dissolved in the dissolved mechanism 4 in a supersaturated state. The liquid dissolved in the dissolution mechanism 4 is depressurized by flowing through a thin tube that is the depressurization mechanism 5, and discharged from the hydrogen water discharge port 10 to the outside.

  Moreover, in the gas dissolving apparatus 1 of the present invention, it is preferable that the inner diameter of the thin tube which is the pressure reducing mechanism 5 is larger than 1.0 mm and not larger than 5.0 mm. By setting it as such a range, it is not necessary to install a plurality of thin tubes to lower the pressure as in the technique described in Japanese Patent Laid-Open No. 8-87771, and the pressure can be lowered. Therefore, it can be easily attached to a water server or the like, and further, manufacture and repair at the time of failure are facilitated, and attachment to the water server or the like becomes easier.

  Furthermore, the gas dissolving device 1 of the present invention preferably has a control mechanism 6 that controls the gas generating mechanism 2 and the pressurized gas dissolving mechanism 3. The control mechanism 6 is connected to a power source by a power plug 61. The control mechanism 6 is connected to the gas generating mechanism 2 and the pressurized gas dissolving mechanism 3 with a wiring 62 connected to the gas generating mechanism 2 and a wiring 63 connected to the pressurized gas dissolving mechanism 3. Yes. Thereby, the gas generation mechanism 2 and the pressurized gas dissolution mechanism 3 can be controlled using electric power.

  Furthermore, the gas dissolving apparatus 1 of the present invention is such that the operation time of the gas generating mechanism and the pressurized gas dissolving mechanism is 5 to 60 minutes by the control mechanism, and is stopped 1 to 5 times the operating time. It is preferable to control the gas generation mechanism and the pressurized gas dissolution mechanism with time, the operation time of the gas generation mechanism and the pressure gas dissolution mechanism is 10 to 30 minutes, and 2 to 2 of the operation time. More preferably, the gas generation mechanism and the pressurized gas dissolution mechanism are controlled with a stop time four times longer, the operating time of the gas generation mechanism and the pressure gas dissolution mechanism is 10 to 20 minutes, and Most preferably, the gas generation mechanism and the pressurized gas dissolution mechanism are controlled with a stop time three times as long as the operation time. By such control, hydrogen can be efficiently dissolved in a liquid in a saturated state. The control can be performed by providing the control mechanism with a timer function.

  Further, the gas dissolving device 1 of the present invention is not particularly limited as long as the pressurized gas dissolving mechanism 3 can pressurize and dissolve the gas into the liquid, but is preferably a diaphragm pump. By using the diaphragm pump, the pressurized gas dissolving mechanism 3 can be provided in a smaller space.

  Furthermore, the gas dissolving device 3 of the present invention preferably has two or more dissolved mechanisms 4. In FIG. 1, it has the dissolution tank 41 and the dissolution tank 42, and can maintain a supersaturated state more stably by this.

  FIG. 2 is a diagram showing an example of use of the gas dissolving apparatus of the present invention. In the figure, 100 is a water server. By attaching the gas dissolving apparatus 1 to the water server 100, hydrogen gas can be generated using the water in the water server 100, and supersaturated hydrogen water can be supplied using the hydrogen gas. Moreover, since supersaturated hydrogen water can be preserve | saved in the water server 100 and it can circulate, supersaturated hydrogen water can always be supplied.

  In the above, an example in which hydrogen is used as the gas is shown, but other gases can be dissolved in a supersaturated state. For example, if a carbon dioxide gas cylinder, a nitrogen gas cylinder, an oxygen gas cylinder or the like is used as the gas generation mechanism 2, various gases can be dissolved with supersaturation.

  However, hydrogen is most preferable as the gas. Hydrogen has a small molecular weight, and it is considered that hydrogen enters between the contents in the liquid, for example, between water and water molecules, and is more likely to maintain a supersaturated state. Moreover, it is preferable that the density | concentration of the hydrogen in the said liquid is larger than 1.5 ppm at 7 degreeC. A supersaturated state can be maintained by exceeding 1.5 ppm.

  In the present invention, when hydrogen is used as the gas, it is preferably hydrogen generated by electrolysis as shown in the hydrogen generation mechanism 21 in FIGS. For example, an aqueous solution containing 25% KOH can be placed in an alkaline electrolytic cell, and this can be electrolyzed to generate hydrogen, which can be used as a gas. As a result, the conventional filling with a hydrogen cylinder requires about 15 MPa, whereas it can be used at a pressure of about 1 MPa or less and can be used more safely. Further, by using hydrogen generated from the hydrogen generation mechanism 21 on-site as a gas, the cost can be remarkably reduced as compared with the case of supplying from a cylinder.

  In the present invention, the liquid is not particularly limited, and water, drinks such as tea and coffee can be exemplified, and water is particularly preferable. Water can dissolve various gases and minimize the influence of other components.

  Furthermore, in the present invention, the pressure of the pressurized gas dissolution mechanism 3 at 20 ° C. is preferably 0.4 to 0.9 MPa, and more preferably 0.3 to 0.5 MPa. By setting the pressure within the range, the gas can be easily dissolved in the liquid.

  Further, in the present invention, the thin tube that is the pressure-lowering mechanism 5 can use a member that can be used for flowing a normal liquid or gas within a range that does not interfere with the effect of the present invention. Can be used. Moreover, it is preferable to have a structure in which no gas leaks, such as vapor deposition of aluminum on the outside of the thin tube.

  Hereinafter, although this invention is demonstrated still in detail using an Example, this invention is not limited to these Examples.
