核电站循环水虹吸出水设计

滨海核电站循环水采用淹没式虹吸管双重出流设计,在保证CC虹吸井合理水位控制基础上,对压力主流道、无压辅助流道及排水暗涵处采取了消能、减泡、拦泡、消涡等措施,并结合外海拦截和化学加药消泡系统,从而使CC出水不仅满足凝汽器真空度要求而且解决了排水泡沫问题。

Design of Circulating Water Siphon Outlet for Nuclear Power Station

The stubttletged siphon double flow has been adopted in nuclear power station at the side of sea, which ensured the water level in CC well under control to maintain the appropriate vacuum degree of condenser. The measurements have been taken to eliminate the foam in the main flow with pressure and auxiliary flow as well as buried drainage culvert, such as the energy dissipation, bubble blockage, bubble elimination and burble deceasing. The above measurements in combination with chemical reagent addition and obstruction meshwork in sea successfully solved the CC foam problem.
