摘要: 简要介绍了除氧器的除氧原理、主要作用;详细描述了岭澳核电站二期采用的STORK型除氧器与红沿河、宁德核电厂采用的淋水盘式除氧器的具体结构、除氧原理。通过分析这两种不同型式除氧器对核电站安全运行和系统设计的影响,提出了红沿河、宁德核电厂淋水盘式除氧器系统相关设计优化方案。结果表明:改进的淋水盘式除氧器的安全性、经济性更高。Abstract: This article briefly describes the deaeration principle and the main functions of the deaerator, introduces the detailed structure and the deaeration principle of STORK deaerator used in LAII （Ling’ao Nuclear power station phase II） and deaerator used in HYH and ND power station. After analyzing the different influence by these two types deaerators on the safety operation and the system design of the nuclear power station, the optimized system design proposal of the deaerator of HYH and ND power station was presented with examples. The conclusion is the safety and the economy of improved Tray-spray steam deaerator is more higher than the other one.
