Technical Field

The invention relates to a plate electrode ozone generator with cathode electrode reverse descaling function, and belongs to the technical field of electrolytic water.

Background

Ozone can be generated by electrolyzing tap water under the action of an electric field and an anode catalyst. The electrolysis process is quite complex, and the generation mechanism of the electrolysis process is as follows:

the anode mainly reacts: 3H₂O ＝ O₃ + 6H⁺ + 6e^–

And (3) side reaction of the anode: 2H₂O ＝ O₂ + 4H⁺ + 4e^–

The cathode mainly reacts: 2H⁺ + 2 e^–＝H₂

The ozone generated by electrolysis is rapidly combined with water to form ozone water, and the ozone water has extremely high oxidation potential. Can react with organic substances in water instantly to oxidize the organic substances to generate stable substances harmless to human bodies, so that the water purifying agent can be used for water purification, disinfection and sterilization. The method for producing ozone water by electrolyzing tap water in the latest prior art is widely applied to the fields of pesticide residues, worm eggs, microorganisms and similar application of a vegetable washer for removing food.

However, there is a side reaction at the cathode during the process of electrolyzing tap water, and calcium and magnesium ions in water will accumulate at the cathode, and scale will be gradually formed on the surface of the cathode, which is difficult to remove, especially the electrolysis efficiency of the water electrolysis device will be seriously affected under the conditions of poor water quality and more scale accumulation. Some applications adopt the method of reverse electrode descaling proposed in patent CN105174386A, i.e. the reverse electrodes of the anode and the cathode, which is only suitable for the anode using noble metals such as platinum, etc., and for some water electrolysis devices using metal oxides as the anode catalyst, if the anode and the cathode are directly reverse electrode descaled, the anode catalyst will rapidly fail.
