Abstract: Electrostatic precipitating apparatus in which particles entrained in a gas stream are charged in an ionization zone established between one or more ionizer electrodes and a movable attractor electrode and collected, by reaction with a transverse precipitation field, in an adjacent downstream zone including a movable dielectric collection surface. The dielectric collection surface may be carried by the same conductive member constituting the attractor electrode. Electric fields that are non-attractive to the charged particles, and that have components directed against gas flow, are established in the vicinity of the ionization zone-collection zone interface, thus increasing collection efficiency by retarding downstream movement of the particles, including turbulence in the gas stream, and creating non-linear precipitation field conditions. A series of such collection zones or of additional ionization zones and associated collection zones may be spaced along the gas stream to further enhance precipitation efficiency and to reduce re-entrainment of particles in the gas stream. The ionizer and attractor electrodes and the dielectric collection surfaces are movable to a cleaning zone remote from the gas stream where collected particles are neutralized and removed.

Abstract: An electrostatic precipitator in which particles entrained in the gas stream are charged electrically by a corona discharge field established in opposition to the gas stream between a plurality of emitter electrodes and a screen attractor electrode upstream of an surrounding the emitter electrodes, inducing turbulence in the stream. The velocity at which the particles pass through the charging field is increased by a dielectric converging-diverging nozzle located across the gas stream closely adjacent the particle charging field to retard migration of the charged particles to the screen attractor. The charged particles are collected downstream of the discharge field on an electrically charged moving dielectric member by which an electric precipitation field terminating at a passive reference electrode is maintained across the gas steam. Charges and charged particles are held on the collection surface of the dielectric member by an electric field created between that surface and a conductive member adjacent the opposite surface of the dielectric member. At a location isolated from the gas stream, the collected particles are removed from the collecting surface.
