Collection Efficiency of Fibrous Filter on Dust Load
As time increasing, the dust particles of air gradually deposited in fibrous filter resulting in the variety of the inner structure of filtration media, which made collection efficiency increase. At this time, the logarithm interpenetration law was no longer valid. In this paper, the mathematics mod...

| description | As time increasing, the dust particles of air gradually deposited in fibrous filter resulting in the variety of the inner structure of filtration media, which made collection efficiency increase. At this time, the logarithm interpenetration law was no longer valid. In this paper, the mathematics model of concentration distribution of dust particles was established according to the law of quality conservation. The models were solved under two assume conditions: the first one was no varying of collecting efficiency of singer fiber with dust load, and another condition was changing of collecting efficiency of singer fiber with dust load. Two calculation formulas of collecting efficiency were obtained, and results of calculation were compared with the relative experiment. The theoretical results were coinciding with experimental ones. Research results showed that two kinds of theories calculation's result were almost homology; it would be applicable in both stationary filtration and non-stationary filtration. And the logarithm interpenetration law was a special case of formulas of this paper. |
