Abstract
It is known experimentally that much larger mist particles than the incoming ones are blown off from a fibrous filter as filtration of fine mists proceeds. However, the mechanism which causes this phenomenon is not yet elucidated.
In this work, the performance of the filter as a coagulator of fine mist particles was investigated by measuring the time dependencies of collection efficiency and pressure drop of the filter, and particle size distribution of mist from the filter.
Based on the experimental observations, a model which is capable of predicting the evolution of filter performance is also proposed.
