放射性厂房不同送风过滤器组合对排风过滤器寿命的影响

Influence of different combinations of supply air filters on life of exhaust air filters in radioactive workshops

通过建立放射性厂房颗粒物浓度平衡模型,分析了排风系统净化过滤器容尘负荷的主要影响因素。实测了6种空气过滤器组合对6个粒径区间粒子的过滤效率,并根据实测效率计算了各空气过滤器组合对试验尘、实测大气尘中粒径≥0.3μm颗粒物的计重过滤效率。分析了某核电厂废物暂存库送风系统不同的空气过滤器组合对排风系统净化过滤器容尘负荷和寿命的影响。

By establishing a particle concentration balance model for radioactive workshops,analyses the main influencing factors of the dust holding load of the purification filter of the exhaust system.Measures the filtration efficiency of six types of air filter combinations for particles in six size ranges,and calculates the filtration efficiency of each air filter combination for test dust and measured atmospheric dust particles with a particle size of≥0.3μm based on the measured efficiency.Analyses the influence of different air filter combinations in the air supply system of a nuclear power plant’s waste storage warehouse on the dust holding load and life of the exhaust system purification filter.
