摘要:

目的 调相机循环冷却水在运行过程中由于浓缩效应导致换热器与冷却水填料出现结垢,影响调相机的安全稳定运行。为了解决循环冷却水的结垢问题,需要添加各种阻垢剂来缓解结垢趋势。 方法 为探究不同配方阻垢剂在不同工况下的阻垢效果,通过极限碳酸盐沉积法和极限碳酸盐浓缩倍率法对PBTCA、HEDP、LQ-8531、TQ低膦阻垢剂、TQ阻垢剂进行阻垢性能评价。利用自制阻垢实验台探究了温度、硬度、添加量对5种阻垢剂阻垢性能的影响。 结果 综合评估得出LQ-8531在5种阻垢剂中阻垢性能最优,其在高硬度高温度环境中也能维持较高的阻垢效率。 结论 研究结果可为高温高盐地区换热设备循环冷却水阻垢剂选型提供有价值的参考。

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.
