Abstract (en)

[origin: EP0734772A1] A filter for use in an electrostatic type dust collector including a flexible sheet-like filtering member pleated into a corrugated configuration in such a manner that alternating crest lines face toward an upstream side of a dust containing gas flow and the remaining alternating crest lines face a downstream side of the gas flow, a first set of electrically conductive or insulating spacers provided between successive facets of an upstream side of the filtering member, and a second set of electrically conductive spacers provided between successive facets of a downstream side surface of the filtering member. The electrically insulating and conductive spacers serve to connect successive facets to each other with keeping a given distance therebetween, and the electrically conductive spacers also serve as electric conductors for applying an electric field. <IMAGE>
