Apparatus for separating particles from a gas stream

Claim 1

Apparatus for the separation of solid particles from a stream of gas comprising: A. a housing having defined therein a chamber and having a gas input port defined in one end region thereof and a gas output port defined in an opposed end region thereof for passage of a gas stream longitudinally through said chamber, B. a plurality of spaced, parallel deflecting plates located in said chamber so as to extend generally diagonally across said chamber transversely relative to the direction of flow of a said gas stream therethrough, the front face of each said deflecting plates being inclined to said gas input port and to said direction of flow, C. wall members connected with each said deflecting plate to define a relatively shallow cavity over and about the rear face of each said deflecting plate said wall members further being connected with each said deflecting plate to define a transversely extending channel along the terminal edge portion of each deflecting plate relative to said direction of flow, the mouth of each channel being in generally parallel relationship to its adjacent said deflecting plate, D. each said deflecting plate having a plurality of small gas flow apertures extending therethrough, E. gas pressurizing means, gas pressure regulating means, and first conduit means interconnecting said gas pressurizing means and said gas pressure regulating means with each one of said cavities, and F. particle collection means and second conduit means interconnecting said particle collection means with an end region of each one of said channels.
