Model for fabric-filter cleaning: single-element and multiple-compartment effects
A model for fractional removal in a fabric filter was applied to filtration systems. A method for allowing for the effect of imperfect cleaning of an element or compartment was developed; it was shown that this must be taken into account when modeling a system. Relations for superficial velocity through a dust-cake layer, as well as the buildup of this layer during filtration when cleaning is imperfect, were shown. Finally, the tools necessary for modeling a multicompartment system are described, and the reasons for changes in penetration when a compartment is taken out of service for cleaning are given. Increases in outlet grain loading can be explained as being due to the removal of the compartment with the highest efficiency, the subsequent increase in gas flow through the other compartments, and the return to filtration by a cleaned compartment with relatively high penetration.
