Abstract
An exhaust treatment system having a water scrubber, a centrifugal water trap for removing water droplets from exhaust flow and a filter for cleaning exhaust gases. The components are housed contiguously so that exhaust piping is not needed between the components. The water trap includes a frustoconical peripheral wall and a plurality of conduits having apertures for directing exhaust obliquely against the wall. The conduit apertures face in the same rotational direction to generate a rotational circulation of exhaust within the trap, which is entirely encircled by an annular filter. The water trap and filter are housed in a portion of the housing that is a low profile flat disc shaped to extend only a limited distance above the scrubber to which it is directly attached.
