摘要：

The periodical filter cleaning process has a marked effect on the filtration performances of fabric filters. A model was proposed to express the non-uniformity of residual dust cake distribution after filter cleaning in a simpler manner, in which two parameters, i.e. the surface cleaning fraction, f, and the residual dust load on un-cleaned surface, R-D, were introduced. Three filter media with different surface finishing were tested and f and R-D were calculated by using the testing results. It can then be concluded that filter with surface finishing of calendar + singe has a better filter regeneration effect than that of singe + calendar. Lamination with PTFE membrane results in an excellent filter regeneration effect.
