摘　　要：原有造气循环水系统采用“闭式微涡澄清器+闭式冷却塔”的工艺进行处理,由于造气循环水采用直接冷却的方式,水质较差,容易造成管道及设备的腐蚀、堵塞等,闭式微涡澄清器和冷却塔经常停休维护,不利于系统的稳定运行。通过采用“平流沉淀池+开式冷却塔”的方式对现有系统进行改造,同时考虑一定的富余量,并保留原有系统备用。The process of"closed micro-vortex clarifier+closed cooling tower"was used to treat the original circulating water system for gas production.Because gas making circulating water adopts direct cooling method,water quality is poor,which can easy to cause corrosion and blockage of pipelines and equipment and so on.Closed micro-vortex clarifier and cooling tower often stop for maintenance,which is not conducive to the stable operation of the system.The existing system was reformed by adopting the method of"Advection Sedimentation Tank+Open Cooling Tower",At the same time considering a certain margin,and keeping the old system in reserve.
