核电厂用高效过滤器介绍

The Introduction of HEPA Filters in Nuclear Power Plant

本文结合核电厂用高效空气粒子过滤器的使用情况,对核电用过滤器分类,效率测试方法尤其是钠焰法、荧光素钠法,阻力及容尘量实际判定方法进行了说明和分析。

Based on the practice of the HEPA filters in the nuclear power plant,this paper introduces the classifications of HEPA filters,and presents a brief descriptions of efficiency tests methods,especially sodium flame method,uranine method as well as the method to measure resistance and dust holding capacity.
