Diaphragm-free type device for circularly electrolyzing hypochlorous acid and sodium hypochlorite

Abstract

The invention provides a diaphragm-free type device for circularly electrolyzing hypochlorous acid and sodium hypochlorite. The device comprises a water softener, a water storage tank, a sodium chloride storage tank, a water supply pump, a saline water conveying pump, a diaphragm-free type electrolytic cell, a hypochlorous acid and sodium hypochlorite storage tank and an electrical control system. The device is characterized in that the diaphragm-free type electrolytic cell is provided with a cooling electrolyte flow-in opening and an electrolyte flow-out opening; an electrolyte output pump, a heat exchanger and an electrolyte input pump are sequentially connected between the electrolyte flow-out opening and the cooling electrolyte flow-in opening; the electrical control system comprises a touch screen, a PLC control module and a rectifier; and control circuits are arranged among the PLC control module, the touch screen, the rectifier, the water softener, the water supply pump, the saline water conveying pump, a conductive electrode of the diaphragm-free type electrolytic cell, the heat exchanger, the electrolyte output pump and the electrolyte input pump. The diaphragm-free type device is high in electrolytic reaction speed, high in hypochlorous acid and sodium hypochlorite yield, high in conversion rate and low in running cost.

Description

technical field [0001] The invention relates to a hypochlorous acid and sodium hypochlorite generating device, in particular to a device for producing hypochlorous acid and sodium hypochlorite by circulating electrolysis without a diaphragm. Background technique [0002] With the development of social science and technology and the improvement of living standards, people pay more and more attention to human health, and the disinfection of drinking water, domestic sewage, swimming pools, food processing plant environment, food materials and tableware in restaurants and public canteens is becoming more and more important. Pay attention to. The prior art mainly contains two kinds of chemical medicine washing and disinfection methods and ozone sterilization and disinfection methods. The use of chemical washing and disinfection methods has problems such as high cost and hazards caused by residual drugs after use. Food processing plants, restaurants, public canteens, especially l...

AI Technical Summary

Problems solved by technology

Ion membrane electrolysis can effectively improve the conversion rate of hypochlorous acid and sodium hypochlorite, but the ion membrane has the disadvantages of short service life, frequent alternate use, easy failure, high production cost, low output of hypochlorous acid and sodium hypochlorite, and slow reaction speed. Therefore, improving the sodium hypochlorite conversion rate of non-diaphragm hypochlorous acid and sodium hypochlorite generators has become an urgent technical problem for those skilled in the art.
