摘　　要：循环水系统框架式正面进水旋转滤网,由于其设计结构原因,对机组的安全性、经济性影响较大,文章提出了将旋转滤网结构形式由正面进水改为网内进水侧向出水的布置形式。通过对循环水泵房的进水流道进行建模,并在各工况下进行模型试验,经对比分析发现,侧面旋转滤网若前移到拦污栅井位置,并在网后设置合适的导流墙,基本可以满足循泵正常运行的要求。The framework type front inlet rotaryfilter screen of the circulating water system has a significant impact on the safety and economy of the unit due to its design structure.The article proposes to change the layout of the rotaryfilter screen structure from front inlet to side outlet inside the network.By modeling the inlet channel of the circulating water pump room and conducting model tests under various operating conditions,it was found through comparative analysis that if the side rotatingfilter screen is moved forward to the position of the trash rack well and a suitable guide wall is set behind the screen,it can basically meet the requirements of normal operation of the circulating pump.
