珠江电厂循环水一次旋转滤网的改造

Alteration of Primary Rotating Filter in Circulating Water in Zhujiang Power Plant

珠江电厂循环水系统采用开式循环方式运行,由于珠江水携带有大量垃圾,同时珠江电厂循环水一次旋转滤网又存在设计缺陷,净水效果差,从而导致凝汽器真空不符合要求,冷却器不能有效工作,威胁机组的安全经济运行。通过用XW C-Ⅱ一次滤网系统对1号机组进行改造,有效保证了循环水水质和水量,一年来的运行实践证明,该次改造是成功的。

An opening system in the circulating water system in zhujiang power plant is adopted. There are large amount of weeds and rubbish in it because of the deteriorating environment ,and the existed design defection in the circulating water primary rotating filter in Zhujiang Power Plant led to lower condenser vacuum and bad coolers efficiency, so it is a intimidator to safety and economy operation of generate electricity units. Alteration of the primary rotating filter in unit 1 with XWC-Ⅱ ,it guarantee the quality and quantity of circulating water efficiently. It was proved that the Alteration of the primary rotating filter in unit 1 is successful through a year operation.
