Automation method for water quality management of open circulation cooling water

摘要

The present invention relates to a method of managing open water circulating cooling water system, which features steel production In the mill open circulating cooling water treatment plants plenty of oil flowing into the cooling water in the process, the sampling pipe means for water analysis on the pipeline that supplies water to the steel production lines for water management automation (8) After installation, , with a constant flow rate of cooling water flow and cooling water flow conditions as pH, oxidation-reduction electric current or the effective residual chlorine concentration (ORP), conductivity, since the analyzer, such as corrosion and adhesion nor, water quality monitoring, and control means to analyze in real-time transmission, by supplying a neutralizing agent and disinfectant according to the set control measures the amount of the neutralizing agent solution feed pump and the disinfectant solution stored in the movable water tank, so control the pH and the effective residual halogen concentration of the cooling water into the water a predetermined range set in advance can be maintained stably.
