Abstract:
An electrostatic precipitator for removing particulate matter from a gas stream, said gas stream flowing through said precipitator, comprising, in combination:a plurality of spaced pairs of corrugated plate electrodes, each of which extends in the direction of the flow of the gas stream and are spaced from each other transverse to the flow direction, said electrodes connected to a first electrical potential; each of said pairs of corrugated plate electrodes forming a plurality of spaced alternating wide zones and narrow zones, the spacing extending in the flow direction; each of said wide zones containing at least one electrically conductive barrier filter in communication with a gas outlet port, said conductive barrier filter being connected to a second electrical potential; each of said narrow zones containing at least one relatively flat elongated electrode, said elongated electrode having a leading and a trailing edge with respect to said gas flow, said elongated electrode essentially parallel to said corrugated plate electrodes, said elongated electrode connected to said second electrical potential; said first and second electrical potentials chosen to cause corona discharge from the leading and/or trailing edges of said elongated electrodes, said corona discharge extending from said elongated electrode to said corrugated plate electrodes.
