ABSTRACT:
An electrostatic precipitation system (100) utilizes laminar flow of a particulate-laden gas in order to enhance the removal of sub-micron sized particulates. The system incorporates a vertically oriented housing (105) through which the gas flows downwardly therethrough to a lower outlet port (110). The gas, which may be a flue gas enters the laminar flow precipitator (102) through an inlet port (108) for passage through a charging section (104). The charging section (104) imparts a charge to the particulates carried by the flue gas. The flue gas and charged particles then flow to a collecting section (106) which is downstream and below the charging section (104). The collecting section (106) is formed by a plurality of substantially parallel tubular members, each tubular member defining a collecting passage therein. Each tubular member (118) is electrically coupled to a potential that is of opposite polarity to that imparted to the particulates, so as to attract the charged particulates to an inner surface thereof. The collected particulates are subsequently collected in a hopper (112) or reentrained in the gas stream as agglomerates for subsequent removal from the gas by a secondary filter (120), the gas stream then being conveyed to a stack (14) wherein the particulate-free gas can be emitted into the atmosphere.
