发电厂蒸发冷却通风空调机组空气过滤器的探讨

摘要

通过对空气过滤器过滤机理、过滤材料以及分类的介绍，并根据蒸发冷却通风空调机组在发电厂中的应用现状，阐释了科学合理选用空气过滤器的重要性。提出为了减缓室外环境中污染物对直接（间接）蒸发冷却器换热性能的影响，应正确选择空气过滤器的类别和级数。%The air filtration theory, air filtration material and classification of air filters are introduced. Based on the current situation of evaporative cooling ventilation and air-conditioning unit used in power plants, these give a explanation of the importance of choose air filters scientifically. In order to slow the effect of evaporative cooler’s heat exchange performance by pollutant in outdoor, the classification and stage of air filters should choose correctly.
