针对多晶硅厂循环冷却水系统水质不稳定造成生产设备事故频发的问题,采用 Puckorius指数理论分析水质稳定性,研究了循环冷却水对设备腐蚀结垢的影响,结合现场实际提出可行的水处理指导。经一年运行监测表明水质指标稳定,设备运行情况平稳。
In view of production equipment accident caused by instable water quality of recirculating cooling water system in polysilicon plant,the water quality stability was analyzed by the Puckorius index theory. The effect of recirculating cooling water on equipment corrosion and scaling was studied. Finally,a feasible water treatment guide was put forward with the actual situation. One year's operation and monitoring indicates water quality is stable and the equipment running status is ideal.
