循环水二次清洗预膜的技术探讨

Technology of Circulating Water Secondary Pre-cleaning Film

化工装置运行一定周期后,因为循环水水质控制因素的复杂性,实际存在各种结垢和腐蚀,因此根据条件会对循环水系统进行二次清洗预膜。但设备的状态和初次投用时已发生了很大的变化,因此清洗预膜的过程难度增大,旁路挂片检测有效性降低,简要对循环水二次清洗预膜过程进行分析总结,为化工装置的循环水系统再次清洗预膜提出切实可行的解决办法以及有效的建议。

The chemical plant is running a certain period,because the circulating water quality control factors of the complexity of the actual existence of various scaling and corrosion,so the secondary pre-cleaning fi lm based on criteria that have circulating water system.But the state apparatus and put into use for the fi rst time when great changes have taken place,so the pre-cleaning fi lm process more diffi cult,reduce the effectiveness of detection bypass coupon briefl y secondary circulating water cleaning pre-fi lm process are summarized,and the circulating water system of chemical cleaning pre-film device again propose practical solutions and effective recommendations.
