循 环 冷 却 水 系 统 的 电 化 学 水 质 稳 定 技 术 案 例 分 析

Scale deposits and metal corrosion in circulating cooling water systems can lead to reduced heat transfer efficiency and increased energy consumption in circulating water systems，seriously affecting the safe and stable operation of industrial production. This paper takes the electrochemical descaling equipment of a plant’s circulating water system as a case study，and provides a basis for the application of electrochemical technology for the treatment of circulating cooling water by analyzing its treatment effects and economic benefits. Operational results from the site show that the electrochemical descaling equipment used in the plant can effectively improve water quality，prevent scaling and control the corrosion of the circulating cooling water system. It can reduce 4.38×10⁵ t of water recharge and discharge from the circulating water system each year，and significantly reduce the amount of chemicals added. Economic calculations show that the electrochemical descaling equipment can save approximately 2.129 million yuan per year.
