摘　　要：根据某核电站AC厂房送风系统要求和框架文件设计了一种可复用的金属空气预过滤器,与核电站原空气预过滤器的安装方案和运行压差进行了对比。结果表明,运行相同时间后,金属空气预过滤器上游、下游压力和压差上升比例均低于原空气预过滤器,表明金属空气预过滤器运行更稳定。达到终阻力时,金属空气预过滤器可清洗后复用,有良好的应用前景。A reusable metal air pre-filter was designed based on the requirements and framework documents of the air supply system in the AC building of a nuclear power plant,and was compared with the installation scheme and operating pressure difference of the original air pre-filter in the nuclear power plant.The results showed that after running for the same time,the upstream and downstream pressure and pressure difference increase ratios of the metal air pre-filter are lower than those of the original air pre-filter,indicating that the metal air pre-filter operates more stably.When the final resistance is reached,the metal air pre-filter can be cleaned and reused,which will have good application prospects.
