Abstract

This chapter provides a description of the working of pollution control hardware, and highlights technologies and equipment that may be applicable to pollution prevention opportunities. Settling chambers, low pressure drop cyclones, and dynamic precipitators are among the most common and important devices applied in end of pipe control applications for dust and particulate matter. In specifying settling chamber dimension, gas flow velocities must be maintained below the re-entrainment velocity of deposited particulate. Fabric filter pulse-jet cleaned type equipment is used for the capture of Particulate Matter (PM), including PM less than or equal to 10 μm. Operating conditions are important determinants of the choice of filter media and sealant used in the cartridges. Practical application of cartridge collectors requires the use of a large media area in order to avoid an unacceptable pressure drop across the filter media. The number of cartridges utilized in a particular collector is determined by the choice of air to cloth ratio, or the ratio of volumetric air flow to filter media area.
