Calculating the size and operating parameters of a slotted filter

Abstract

The calculation method that yields rational ratios of the thickness of the filter layer and the rate and time of filtration of a slotted filter that provide the target cleaning efficiency of dusted gases in processes at a constant filtration rate has been proposed. The method is based on the concepts of stationary factor and residence time of dusted gas in the filter layer; it considers the efficiency decrease caused by the secondary dust entrainment. It helps to determine the necessary data for the design of a slotted filter that has any target capacity and cleaning efficiency.
