ABSTRACT:
A method and system for collecting fine particles from a gas stream is disclosed. A shallow dense mobile bed of solid collector granules is moved over a plate containing a plurality of perforations; and a gas stream containing fine particles is moved upward through the perforations to form high velocity gas jets moving upward through the granule bed for causing the collector granules to collect the fine particles from the gas stream by inertial impaction and interception. The bed is only deep enough in relation to the velocity of the gas jets to prevent the gas jets from penetrating the bed without the fine particles therein being collected by the granules. The granule bed is not more than approximately one inch deep. Preferably the granules are moved over a plurality of perforated plates that are positioned in tandem vertically, and the gas stream is moved successively through the perforations in the plurality of plates and thereby through the granules that are moving across the plurality of plates.
