水垢沉积和金属腐蚀会导致循环冷却水系统传热效率下降和能耗增加,严重影响工业生产的安全稳定运行。以某厂循环水系统的电化学除垢设备为案例,通过分析其处理效果和经济效益,为电化学技术处理循环冷却水的应用推广提供依据。现场所得运行数据表明,该厂所采用的电化学除垢设备能够有效改善水质,防止结垢,控制循环冷却水系统的腐蚀情况。每年减少循环水系统补水量和排污量各4.38×10^(5) t,并显著降低药剂投加量。经济核算显示该电化学系统每年可节省约212.9万元。

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 4.38×10^(5) 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.
