循环冷却水系统的日常运行与管理

加强循环水系统管理的目的是在保证循环冷却水温度、压力、流量的基础上,保持水质良好,防止设备腐蚀和结垢,提高设备的使用寿命和取得良好的经济效益。详细介绍了尿素装置循环冷却水系统的日常监控项目,对减少不良水质对设备的腐蚀因素进行分析并提出相应的减缓腐蚀的措施,对循环冷却水系统日常监测及巡检工作、黏泥剥离方案及特殊情况的处理提出相应的措施。

Routine Operation and Management of Circulating Cool Water System

The aim of tightening up the management of the circulating cooling water system is on the basis of ensuring the temperature, pressure and flowrate of the circulating cooling water to maintain the water quality in a good condition, prevent the equipment from corrosion and scaling, lengthen the service life of the equipment, and reap good economic benefit. A detailed explanation is given of the routine monitoring items of the system in the urea unit, an analysis is made of a decrease in corrosion factors of the equipment by poor water quality, with relevant measures suggested for slowing down the corrosion rate, routine monitoring and rounds of inspection of the system, schemes for stripping slime and handling of exceptional cases.
