Abstract
A multi-stage system is diclosed for removing particles from a gaseous medium and comprises an upstream precipitating stage (10) of spaced corona discharging wires between parallel collecting plates, followed by a downstream precipitating stage (12) having one or more electrically charged shells (30) with flat sides generally parallel to collecting side plates (24, 26) for providing a uniform electric field in the medium carrying space, the sides of the shell having openings (55) through which ions generated in the interior pass into the gaseous medium. A corona discharge apparatus (62, 64, 68) inside the shell produces the ions at predictable, generally uniformly spaced locations. Alternative embodiments of the system include another stage located ahead of the upstream stage for removing the larger particles in the gaseous medium which can comprise a gravitational precipitator, a cyclone separator, a low voltage electrostatic precipitator or a low voltage ion beam generator. A further embodiment of the system includes a downstream electrostatic precipitator stage for recharging and removing particles which may become reentrained in the gaseous medium after initial collection thereof.
