A water electrolysis device

Abstract

The invention discloses a water electrolysis device, comprising an electrolysis unit, a water tank, a gas-liquid mixer, a gas-liquid separator and a power supply. The electrolysis unit comprises a shell, top of the shell is provided with a water intake, and an anode titanium electrifying pore plate, a beta-PbO2 anode catalytic plate, a solid polymer electrolyte membrane, a Pt/C cathode catalytic plate and a cathode titanium electrifying pore plate are arranged under the water intake; the bottom of the water tank is provided with an engaging interface while the top thereof is movably provided with a top cover, the top cover is provided with an ozone outlet pipe and a water supply port, and the water tank is provided with an ozone outlet; the gas-liquid mixer comprises a mixer container on which an ozone inlet, the water intake and an ozone water outlet are arranged; the gas-liquid separator comprises a separator container on which a hydrogen water intake, a hydrogen outlet pipe and a water outlet are arranged; an anode of the power supply is connected with the anode of the electrolysis unit, and the cathode of the power supply is connected with the cathode of the electrolysis unit.The water electrolysis device can electrolyze water into ozone, ozone water, hydrogen and hydrogen-contained water, is simple in structure, less in energy consumption and lower in cost, and can be widely used.

Description

technical field [0001] The invention relates to a water electrolysis device. Background technique [0002] Ozone is a strong oxidant, which has strong functions of instant sterilization, sterilization, disinfection, deodorization, decolorization, preservation, etc., and can also decompose organic matter that is difficult to decompose. In the field of public health and medical treatment where infectious diseases and viruses are prevalent, the environmental field of air pollution and water pollution, the industrial field of food and pharmaceuticals, the cleaning field of the electronic industry, the disinfection of tap water and drinking water, industrial wastewater and nuclear waste, etc. In the field of decomposition and treatment of difficult chemical substances, its application is already very important. [0003] The application of ozone has two aspects: one is the application of ozone body, which is mainly used for disinfection and purification of air, decomposition of m...

AI Technical Summary

Problems solved by technology

[0010] (1) Since ozone is a strong oxidant, all over-current parts must be made of materials with strong corrosion resistance, such as titanium alloy, stainless steel 316 or above, or resin materials such as polytetrafluoroethylene PTFE and PFA. There are many connections, and it is difficult to connect materials, resulting in quite expensive costs. The complex structure will complicate the control systems of water supply, liquid level, temperature, etc., and also increase the difficulty for users in management, operation, and maintenance. Large, these have caused application limitations;

[0011] (2) Limited by its process, once the power supply is interrupted, the β-PbO in the anode catalytic layer 2 It is very easy to restore and deteriorate, and it takes a long time to reach a certain current efficiency and concentration when restarting. Therefore, once the current is applied, the power cannot be cut off. The device needs to be equipped with a battery or emergency backup power supply, so it is difficult to popularize;

[0012] (3) The ozone concentration of the ozo...
