            摘要:

            通過建立放射性廠房顆粒物濃度平衡模型,分析了排風系統凈化過濾器容塵負荷的主要影響因素。實測了6種空氣過濾器組合對6個粒徑區間粒子的過濾效率,并根據實測效率計算了各空氣過濾器組合對試驗塵、實測大氣塵中粒徑≥0.3 μm顆粒物的計重過濾效率。分析了某核電廠廢物暫存庫送風系統不同的空氣過濾器組合對排風系統凈化過濾器容塵負荷和壽命的影響。

            Abstract:

            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 0.3 μm 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.
