调相机循环冷却水阻垢剂筛选实验及静态阻垢性能评估
Screening Experiments and Static Scale Inhibition Performance Evaluation of Scale Inhibitors for Synchronous Condenser Circulating Cooling Water
摘要
Abstract
[Objectives]During the operation of the circulating cooling water of the regulating camera,the concentration effect leads to the scaling of the heat exchanger and the cooling water packing,which affects the safe and stable operation of the regulating camera.[Methods]In order to solve the scaling problem of circulating cooling water,it is necessary to add various scale inhibitors to alleviate the scaling trend.In order to explore the scale inhibition effect of different formulations of scale inhibitors under different working conditions,the scale inhibition performance of PBTCA,HEDP,LQ-8531,TQ low phosphine scale inhibitors and TQ scale inhibitors was evaluated by limiting carbonate deposition method and limiting carbonate concentration ratio method.The effects of temperature,hardness and dosage on the scale inhibition performance of five kinds of scale inhibitors were studied by using self-made scale inhibition test bench.[Results]The comprehensive evaluation shows that LQ-8531 has the best scale inhibition performance among the five scale inhibitors,and it can maintain high scale inhibition efficiency in high hardness and high temperature environment.[Conclusions]The research results provide a valuable reference for the selection of scale inhibitor for circulating cooling water of heat exchange equipment in high temperature and high salt area.关键词
