It should be understood that, in the apparatus for preparing hydrogen-rich water provided in the embodiment of the present invention, the hydrogen bubbles are not easy to crack due to their small size, and the principle is as follows: since the hydrogen bubbles are tiny and are micro-scale or nano-scale, the bubble floating speed can be calculated according to the Stokes formula R ═ ρ gd2/18 μ (ρ ═ density, g ═ gravity acceleration, d ═ bubble diameter, μ ═ viscosity). The floating velocity on the bubble is proportional to the square of the bubble diameter, and this relationship is only applicable to small bubbles. Large bubbles with a diameter greater than 2mm do not suffer from diameter variations due to shape variations. Nanobubbles below 1 micron rise very slowly, well below brownian motion, and appear as no rise overall.

And due to the reduction effect of hydrogen, experiments prove that the negative potential of the high-pressure hydrogen-rich water can reach 800-900MV through the measurement of the oxidation-reduction potential OPR, the bubbles have zeta negative potential, and the mutual electrostatic repulsion can limit the fusion of the bubbles. Since the smaller the bubble, the more energy is required, and therefore the small bubble breakup does not easily occur. Therefore, small bubbles can grow or shrink, but fusion and rupture do not easily occur (mattesy effect).

The process comprises three times of generation of micro bubbles: injecting high-pressure hydrogen into the pressure reaction tank for the first time, wherein the high-density membrane only allows the hydrogen to pass through, and undissolved hydrogen can be combined with water to generate micron-nanometer bubbles; hydrogen is transferred from high pressure to a low pressure reaction tank, and is fully mixed with water for the second time to generate bubbles for storage; the third time is when opening valve 17, and pressure reduces, and high low pressure's change can promote aquatic again to generate a large amount of micro-nano bubbles.

Experiments show that under 5 standard atmospheric pressures, a 10 gallon pressure reaction bin with a diameter of 50cm is selected, and after 6 hours, the negative potential in the capsule in the pressure bin can reach about 700 MV; if a 50-liter pressure reaction tank is selected, the negative potential in the capsule in the pressure cabin can reach about 700MV after 10 hours. Set up gas-liquid mixing device before the pressure retort, if gas-liquid mixing pump 8, earlier carry out the primary mixing of hydrogen and water under the ordinary pressure state, during gas-liquid mixture gets into the pressure chamber inner bag through the inlet again, then can shorten reaction time greatly. Besides, a plurality of pressure bins with gradually decreased pressure are selected for connection, the contact area of the hydrogen and the pressure bin inner bag is increased, and the pressure is increased.

The particular features, structures, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
