Novel electrochemical/photocatalysis circulating cooling water treatment device

Abstract

The invention relates to a novel electrochemical / photocatalysis circulating cooling water treatment device used for treating circulating cooling water and device self cleaning, and belongs to the field of water treatment. The novel electrochemical / photocatalysis circulating cooling water treatment device mainly comprises an electrolysis unit and a photocatalytic unit. The electrolysis unit is capable of removing ions in the circulating cooling water via electrochemical electrolysis technology, and preventing scaling and removing scale, wherein scaling is easily caused by the ions; the photocatalytic unit possesses high efficiency sterilization and algae extermination performance on circulating cooling water via photocatalysis technology. Innovations of the novel electrochemical / photocatalysis circulating cooling water treatment device are that: 1, organic combination of advantages of two water treatment technologies, including electrochemistry and photocatalysis, is realized, complementary performance of the two technologies is fully used, equipment comprehensive water treatment effect is improved, and a problem that comprehensive performance of single utilization is poor is solved; 2, polarities of the cathode and the anode of an electrode module are switched, cathode surface automatic descaling is realized under low current intensity in a short time; a rapid flow water washing nozzle arranged on the top of a photocatalysis box body can be used for washing pollutants on photocatalysis nets and ultraviolet lamps.
