摘要：

There are few studies on the correlation between the weighting and counting efficiencies of filter media of bag dust collector，which leads to the fact that its filtration performance cannot be accurately evaluated. Two factors that affect the weighting and counting efficiencies of the filter media were analyzed through building a filtration performance test platform. The results show that the filtration efficiency decreases with the increase of filtration velocity，and the filtration efficiency of low-efficiency filter media decreases more than that of high-efficiency filter media. Compared with alumina powder，the filtration efficiency of filter media under atmospheric dust source environment is more easily affected by the filtration velocity. The weighting and counting efficiencies of low-efficiency filter media under the two kinds of dust sources environment are quite different. The filtration efficiency of the filter media under alumina powder environment is significantly higher than its filtration efficiency under atmospheric dust source environment. The dust source has little effect on the filtration efficiency of high-efficiency filter media. It is more reasonable to use both the weighting and counting efficiencies to characterize the filtration performance of filter media. © 2025 Northeast University. All rights reserved.
