ABSTRACT:
An apparatus for electrically separating particles from a gaseous stream in which high-tension means and a plurality of earthed collecting means are positioned in a housing having inlet and outlet means for flow of the gaseous stream therebetween. The high-tension means is connected to a source of high voltage direct current and charges the particles in the gaseous stream. The plurality of earthed collecting elements are disposed in the gaseous stream in the housing to collect charged particles in the gaseous stream. Each collecting element comprises a matrix of alternate flat paper strips and corrugated paper strips glued to each other to form through-flow channels for the gaseous stream. The periphery of the matrix is connected with an electrically conducting, earthed metallic layer to form a block of corrugated paper with edge portions connected to current conducting earthing means. The block of corrugated paper is divided into layers along at least some of the flat paper strips and interleaved between the layers with electrically conducting metal foil each connected to the earthed metallic layer along the periphery of the block. The housing has an opening to receive the collecting elements therein and the housing includes supporting means for supporting the collecting elements in the gaseous stream within the housing. The high-tension means are disposed between the collecting elements in the housing, preferably with at least one collecting element positioned between the first high-tension means and the inlet.
