摘要： A multi-stage system is disclosed for removing particles from a gaseous medium and comprises an upstream precipitating stage of spaced corona discharging wires between parallel collecting plates, followed by a downstream precipitating stage having one or more electrically charges shells with flat sides generally parallel to collecting side plates for providing a uniform electric field in the medium carrying space, the sides of the shell having openings through which ions generated in the interior pass into the gaseous medium. A corona discharge apparatus 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.

摘要： An electrical precipitator which uses a combination of field charging, diffusion charging, and electron charging for the enhancement of fine particle charging and collection. A precipitator is described for the collection of fine particles of less than 1.0 micron in diameter from an effluent by enhancing the charge thereon by electrons of high kinetic energy. Another feature of the invention describes a precharging stage which can be added to the electron charging stage, or other conventional precipitator stage, that operates the basis of ion bombardment or diffusion of thermally active ions. The precharging stage charges the fine particles and they can later be increased in charge and precipitated by the electron charging stage. Another feature of the invention describes disposing a conventional stage for coarse particulates over 1.0 micron in diameter between the diffusion charging stage and the electron charging stage.

摘要： A system is disclosed for removing particles from a gaseous medium and comprises an upstream precipitating stage followed by a downstream precipitating stage having one or more electrically charged shells with corona discharge apparatuses therein which produce ions at predictable, generally uniformly spaced locations. The shells have flat sides and openings at the upstream and downstream ends so as to permit a portion of the gaseous medium to flow through the interior of the shell and flat sides which act as collecting means. The flat sides of the shells are generally parallel to collecting side plates for providing a uniform electric field between the shells and collecting plates, the sides of the shells having openings to permit the passage of ions generated in the interior of the shell.
