Abstract:
A laminar flow, wet electrostatic precipitator for collecting matter from a gas stream flowing through a flue, the laminar flow, wet electrostatic precipitator comprising:a) at least one substantially planar discharge electrode disposed in the gas stream substantially parallel to a direction of flow of the gas stream, the discharge electrode having an electrical charge; b) at least one substantially planar collecting electrode disposed in the gas stream substantially parallel to the discharge electrode and close enough to the discharge electrode that a portion of the gas stream flowing between the electrodes has substantially laminar flow characteristics, the collecting electrode being made of a substantially water-saturated porous membrane having a water-wetted, exterior surface, the collecting electrode having an electrical charge that is opposite in polarity to the electrical charge of the discharge electrode, thereby forming an electric field between the electrodes to cause particulate matter from the gas stream to be precipitated onto the collecting electrode during operation; and c) at least one charging electrode disposed in the gas stream upstream of said at least one collecting electrode for charging at least some of the matter in the gas stream before the matter flows between the collecting and discharge electrodes.
