粤东海门岬角动力及取排水工程比选研究

Analysis on the dynamic process and intake and drainage outlets engineering application of Haimen Cape in East Guangdong

基于流动结构特征进行火/核电厂优化取排水口工程布置,对于提高工程运行效率、降低工程投资有重要意义。本文建立了粤东海门岬角附近海域水域温排水数学模型,对四种类型14个分列式取排水口布置方案进行了比较分析,并提出类似地形、流动结构条件下取排水口的布置原则。结果表明南取北排方案符合粤东沿岸流及海门岬角西侧广澳湾近岸潮流运动规律,是合理的布置方案。防波堤阻隔作用不足以使南取北排方案成立。其他方案不成立原因是取排水口之间的距离稍短,存在一次“短路”现象。

Optimizing the layout of intake and drainage outlets of thermal or nuclear power plans based on flow structure is of great significance to improve the operation efficiency and reduce the project investment. In this paper, a numerical model of cooling water is established in the sea area near the Haimen Cape in eastern Guangdong Province. The layout schemes of 14 separate intake and drainage outlets of four types were compared and analyzed, and the layout principles of intake and drainage outlets under similar topography and flow structure conditions were put forward. The results showed that the South-intake & North-drainage drainage scheme is a reasonable layout scheme, which accords with the coastal current of Eastern Guangdong and the tidal current movement law of Guang'ao Bay on the west side of Haimen Cape. The barrier function of the breakwater was insufficient to enable North-intake & South-drainage scheme. Other schemes were infeasible due to the short distance between the intake and outlet, and there is a “short circuit” phenomenon in the water intake.
