Example Embodiment

[0029] Please check figure 1 , A device for producing heavy water using natural water, including an electrochemical reaction device 10, a vessel body 20, a gas extraction device 30, a deuterium extraction device and a reactor.

[0030] The body 20 is used for the flow of water supply, and is provided with a flow channel for the flow of water supply, such as an electrolytic cell. In this embodiment, the electrolytic cell is taken as an example but not limited to the electrolytic cell. Other structures only need to be capable of flowing water or storing water, and the electrode unit can be inserted and the electrode unit can contact water. The body is made of insulating material.

[0031] The electrochemical reaction device 10 includes an electrode unit and a power supply unit 11 electrically connected to the electrode unit. The electrode unit includes an anode 12 and a cathode 13.

[0032] The anode 12 adopts a material with high catalytic activity and low oxygen evolution (characte...

Abstract

The invention discloses heavy water production equipment and a heavy water production method thereof.The equipment comprises an electrochemical reaction device.The electrochemical reaction device comprises an electrode unit and a power unit electrically connected with the electrode unit.The electrode unit comprises a positive electrode and a negative electrode.The electrode unit enables water to undergo an electrochemical reaction, thus, .OH free radicals can be generated at the positive electrode, and H ions and D ions can be generated at the negative electrode; the H ions can be recombined with the .OH free radicals to form water more easily than the D ions, so that there are D ions which are combined by themselves to react to generate deuterium and precipitate; gas which is separated from a water body and contains deuterium is collected, and deuterium and oxygen react to generate heavy water.The equipment has the advantages of being simple, easy to control and low in energy consumption, water consumption and extraction cost.

Description

technical field [0001] The invention relates to heavy water production equipment and a heavy water production method thereof. Background technique [0002] Deuterium is an isotope of hydrogen and is the core raw material for thermal fusion reactions. Because there is one more neutron in the deuterium nucleus than protium, the atomic weight of deuterium is larger than that of protium, which is 2.014. Deuterium water widely exists in natural water. The content of deuterium in glacier snow mountain water is 130-135ppm (mass content is 0.013-0.0135%), the content of deuterium in natural water in plain areas is 150ppm, and the content of deuterium in coastal areas is slightly higher, near the equator and equator region is 155ppm. The production methods of existing heavy water (deuterium water) mainly contain several kinds such as freezing method, rectification method, electrolysis method and exchange method. [0003] Freezing method: Using the principle of different freezing p...
