Abstract

Abstract Discloses an electrostatic precipitator of the two chamber type and specifically, a parallel plate electrostatic cell for the precipitation chamber of said precipitator. The parallel plate electrostatic cell is made up of a plurality of identical modular electrode units in the form of louvered plates, having reinforcing ribs and projecting vanes which are mounted so that the vanes of one plate are interleaved with the vanes of an oppositely charged plate and so that the plates are in parallel and insulated relationship one to the other. The projecting vanes form a plurality of open air passages and a plurality of electrostatic fields across said open air passages.
