Description

technical field [0001] The invention relates to the technical field of seawater treatment, in particular to a system for producing chlorine by electrolysis of raw seawater and a pickling method. Background technique [0002] Due to the existence of marine organisms in seawater, such as barnacles, mussels, seaweeds and algae, these marine organisms have strong adhesion. When they and their spores or eggs enter the cooling water system of the condenser, they tend to attach and breed on the pipe wall, increasing the resistance of the pipe, seriously affecting the heat exchange effect of the condenser, and ultimately affecting the output and safe operation of the steam turbine. . [0003] The electrolytic seawater chlorine production device converts the AC10KV alternating current into direct current through the rectifier transformer and rectifier, and applies it to the cathode and anode of the seawater electrolyzer to electrolyze the seawater to generate active chlorine, which ...

AI Technical Summary

Problems solved by technology

[0005] The existing technology involves a single operation mode of the electrolytic seawater chlorine production system, which cannot be used as a backup for each other, and the operation reliability is poor. The sediment, algae, and shellfish carried in the original seawater can easily block the circulation channel of the chlorine production generator and the electrode contact end surface, resulting in Chlorine generators have frequent daily failures, and the frequency of outage backwashing and pickling has greatly increased; and the existing technology involves complex operations in the pickling process of seawater chlorine production systems, low degree of automation, poor cleaning effect, and long equipment outage periods
