Research and Design of Self-Powered Electrolytic Seawater Chlorination Sterilization and Antifouling System

A wind driven rotating disc friction nano generator (WRD-TENG) as the main body, combining with solar cells, energy storage lithium batteries, and time-controlled switches, and a self powered chlorine analysis system with precise time control was successfully constructed. The test results show that the active chlorine generated by the DSA electrode′s electrochemical analysis of chlorine for 20 minutes had a significant killing effect on pseudomonas aeruginosa and staphylococcus aureus, with all the bactericidal rates over 95%. The solar cells and WRD-TENG of the self-powered system could collect energy separately or simultaneously, and their outputs were complementary. Lithium batteries and time-controlled switches endowed the composite system with energy storage and precise time-control characteristics, and the composite system could successfully drive the electrolytic chlorine evolution system.
