Abstract—The periodical filter cleaning process has a marked
effect on the filtration performances of fabric filters. A model II. A MODEL FOR REGENERABLE FABRIC FILTERS
was proposed to express the non-uniformity of residual dust cake
distribution after filter cleaning in a simpler manner, in which of residual dust distribution expression
two parameters, . the surface cleaning fraction, , and the N. Mao et. al. (2005) proposed a new model that focuses on
residual dust load on un-cleaned surface, , were introduced. the residual dust distribution after each filter regeneration
Three filter media with different surface finishing were tested
operation. In order to express the non-uniformity of residual
using VDI type-1 test rig and and were calculated by using the
testing results. It can then be concluded that filter with surface dust cake distribution after filter cleaning in a simpler manner,
finishing of calendar + singe has a better filter regeneration effect the model introduces two parameters, . the surface cleaning
than that of singe
