ABSTRACT:
A Particulate Matter Filtration System, finding application for the filtration of particulate matter which is present in the combustion exhaust gases of internal combustion engines in general, manufacturing processes resulting in the generation of industrial factory exhaust, coal, wood or oil fired furnaces and the like and all particulate laden gas streams. The system comprises a rotating filter assembly comprised of a plurality of materials suitable for the filtration of such particulate matter from all particulate laden gas streams and is of sufficient volumetric construction in order to provide the proper filtering and flow with respect to the volume of gases generated by a particular application, an outer shell enclosure providing a radial boundary to confine the particles, a collector for the particles to come to rest in, and having a drive to provide the necessary rotational speed to provide aerodynamic and centrifugal forces. The exhaust gases are temporarily confined in the outer shell enclosure by a seal near the exit end of the unit and are forced to pass through the rotating filter assembly to exit the particulate matter filtration system. As particulates accumulate on the outer surface of the rotating filter assembly, they are caused to be spun off by aerodynamic and centrifugal forces acting to lift them from the filter element surface. The particulates combine with other particulates achieving a sufficient density, whereby settling occurs due to terrestrial gravitational forces into the collector for subsequent removal.
