缓蚀是发电机组循环冷却水水质稳定处理中不可缺少的环节。对于珠三角地区而言,更是如此。这是因为珠江水系中,东江水的水质硬度、碱度较低,属腐蚀性水质。东莞塘厦电力有限公司对使用东江水为循环冷却水的系统进行了以缓蚀为核心的水质稳定处理研究与实践,对使用的水质处理药剂进行反复试验和检测,以验证其处理效果;同时,加强对水质的管理和系统运行的监控,使循环冷却水的缓蚀、阻垢和杀菌灭藻处理取得了良好的效果。
Corrosion inhibition is an indispensable link in the process of stabilizing the quality of circulating cooling water of generating units. For the Pearl River Delta region, even more so. This is because the Pearl River water system, the Dongjiang water hardness, alkalinity lower, is a corrosive water quality. Dongguan Tangxia Electric Power Co., Ltd. on the use of Dongjiang water as the cooling water circulation system to corrosion as the core of the stability of water treatment research and practice of the use of water treatment reagents for repeated testing and testing to verify the treatment effect; the same time , To strengthen the management of water quality and system operation monitoring, so that the cooling water corrosion, scale and sterilization algae treatment achieved good results.
