[Method for producing hydrogen water]
FIG. 4 is a flowchart showing the hydrogen water production method of the hydrogen water production apparatus 100. Hereinafter, the hydrogen water production method of the hydrogen water production apparatus 100 will be described with reference to FIG.

(Step S01: Water supply)
In step S01, water in the first and second tanks 41 and 51 is supplied to the anode side space 11a and the cathode side space 11b.

First, water is supplied to the first and second tanks 41 and 51. At this time, since the filters F1 and F2 are attached to the water supply ports 41a and 51a of the first and second tanks 41 and 51, the water supplied to the tanks 41 and 51 is filtered and included in this water. Impurities and odors are removed.
In step S01, water purified using a filter having filters F1 and F2 may be supplied to the first and second tanks 41 and 51.

  The water supplied to the first and second tanks 41 and 51 is typically tap water, but is not limited thereto, and may be deaerated water, distilled water, pure water, ultrapure water, or the like. . Moreover, it is preferable that the water temperature of the water supplied to the 1st and 2nd tanks 41 and 51 is 20 degrees C or less, for example.

  Next, the first and second pumps 42 and 52 suck water in the tanks 41 and 51, and pump the sucked water. At this time, the amount of water supplied to the anode side space 11a and the cathode side space 11b by the first and second pumps 42 and 52 is about several liters to several tens of liters.

Subsequently, by adjusting the first and second valves V1 and V2, the first and second pressures and the flow rate of water flowing into the dissolution unit 20 are adjusted.
Specifically, the first and second valves V1 and V2 are adjusted so that the first pressure is 0.3 MPa or more and the second pressure is 0.1 MPa or more and 0.2 MPa or less. In step S01, the first pressure may be set to 0.4 MPa or less by adjusting the first and second valves V1, V2, and the flow rate may be set to about several L / min.

  In order to adjust the first and second pressures and the flow rate, it is possible not only to adjust the first and second valves V1 and V2, but also to adjust the inner diameter of the transport unit 30, for example. In this case, it is preferable that the inner diameter of the conveyance unit 30 is about several tens of mm.

(Step S02: Electrolysis)
In step S02, hydrogen and oxygen are generated by electrolyzing the water supplied to the anode side space 11a. At this time, hydrogen becomes fine bubbles and is generated from several tens to several hundreds ml per minute from the cathode 12 b of the water electrolysis cell 11.

Here, in this embodiment, the particle size of the fine bubbles (hydrogen) can be further reduced by making the electrodes 12a, 12b (titanium substrate) of the water electrolysis cell 11 into a porous shape or a mesh shape. . Specifically, fine bubbles (hydrogen) having a particle size of about several μm to several tens of μm can be generated.
As a result, in step S03, which will be described later, it is possible to dissolve a large amount of fine bubbles (hydrogen) in water, and high-concentration hydrogen water can be produced.

  The method of reducing the particle size of the fine bubbles (hydrogen) is not limited to the above method, and the mixed water generation unit 10 can also apply a pulse voltage to the water electrolysis cell 11. Specifically, the particle size is several μm by applying a pulse voltage of 0.1 to 200 V to the water electrolysis cell 11 under a condition where the pulse frequency is 1 to 1000 Hz and flowing a current of 1 to 100 A. It is possible to generate fine bubbles (hydrogen) of about tens of μm.

  On the other hand, the oxygen generated in step S03 is dissolved in water supplied to the anode side space 11a and becomes oxygen water. This oxygen water is pumped to the first tank 41 by the discharge pressure of the first pump 42. Thereby, it becomes possible to reduce the power consumption of the mixed water production | generation part 10 rather than releasing the oxygen which generate | occur | produced by electrolysis as it is to air | atmosphere.

  In step S02, since the first pressure is adjusted to be 0.3 MPa or more in the previous step S01, the mixed water generating unit 10 is configured so that the water electrolysis cell 11 is in water having a pressure of 0.3 MPa or more. Mixed water containing the generated fine bubbles (hydrogen) is generated in the cathode side space 11b. This mixed water contains about several percent to several tens percent of fine bubbles (hydrogen) when the volume of the mixed water is 100%, and a small amount of fine bubbles are dissolved.

(Step S03: dissolution)
In step S03, fine bubbles (hydrogen) mixed in the mixed water generated in the previous step S02 are dissolved.

  In step S03, first, the conveyance unit 30 conveys the mixed water generated in the mixed water generation unit 10 to the first dissolver 20a by the discharge pressure of the second pump 52. Here, since the first pressure is adjusted to be 0.3 MPa or more in the previous step S01, the transport unit 30 is mixed with the mixed water in the process of transporting the mixed water to the dissolving unit 20. The fine bubbles (hydrogen) are dissolved under pressure.

  FIG. 5 is a diagram illustrating a state in which the mixed water is being stirred in the first dissolver 20a. In addition, the dashed-dotted line shown in FIG. 5 shows the locus | trajectory of the mixed water which flows in the 1st dissolver 20a typically.

  The mixed water conveyed to the first dissolver 20a flows through the first dissolver 20a as shown in FIG. 5 and is stirred by colliding with the baffle wall 221a. Thereby, the fine bubbles (hydrogen) mixed in this mixed water are dissolved, and hydrogen water is generated.

Here, in the step in which the first dissolver 20a agitates the mixed water, the second pressure is adjusted to be 0.1 MPa or more and 0.2 MPa or less in the previous step S01.
By setting the first pressure to 0.1 MPa or more, the mixed water can be stirred while suppressing the release of fine bubbles (hydrogen) from the mixed water.
Further, by setting the second pressure to 0.2 MPa or less, the fluidity of the mixed water conveyed to the first dissolver 20a is improved, and the mixed water easily collides with the baffle wall 221a. Thereby, the stirring efficiency which stirs mixed water improves.

  Next, the hydrogen water produced | generated in the 1st dissolver 20a is conveyed by the discharge pressure of the 2nd pump 52 to the 2nd dissolver 20b. Thereby, hydrogen water is stirred under the pressure of 0.1 MPa or more and 0.2 MPa or less, and fine bubbles (hydrogen) mixed in the hydrogen water are dissolved.

  That is, the dissolving unit 20 according to this embodiment includes the first dissolver 20a and the second dissolver 20b provided in multiple stages, so that the second dissolver 20b is added to the hydrogen water generated by the first dissolver 20a. Can be used to further dissolve fine bubbles (hydrogen). This makes it possible to produce high-concentration hydrogen water.

(Step S04: Drainage)
In step S04, the hydrogen water generated by the dissolution unit 20 is drained. In step S04, the hydrogen water may be drained via the flow path P7, but may be drained to the second tank 51 via the flow path P8.

In the present embodiment, the second pump 52 sucks the hydrogen water in the second tank 51 and supplies this hydrogen water to the cathode side space 11b (step S01), and the step of electrolyzing the water (step S02). ), The step of dissolving the fine bubbles (hydrogen) mixed in the hydrogen water (step S03) and the step of draining the hydrogen water (step S04) may be repeated.
In this case, the number of times the above process is repeated is about several times to several tens of times. Thereby, it becomes possible to manufacture hydrogen water with a higher concentration.

(Operation of the above manufacturing method)
The hydrogen water production apparatus 100 according to this embodiment generates mixed water in which a small amount of fine bubbles (hydrogen) are dissolved in the cathode-side space 11b, and finely conveys the mixed water under a pressure of 0.3 MPa or more. Bubbles (hydrogen) are further dissolved under pressure.
And the fine bubble (hydrogen) can be further melt | dissolved when the melt | dissolution part 20 stirs mixed water under the pressure of 0.1 Mpa or more and 0.2 Mpa or less. That is, the process of dissolving fine bubbles (hydrogen) can be performed in three stages. Thereby, it becomes possible to manufacture hydrogen water with a higher concentration.

  Examples of the present invention will be described below.
