ABSTRACT:
A low velocity converging flow filter for removing at least part of the solids content from a solids-bearing fluid or fluid mixture comprising a generally conically shaped housing the larger diameter end of which forms an inlet for the fluid or fluid mixture and the smaller diameter end of which an exit therefor, a plurality of spaced, annular segments of progressively decreasing diameter being mounted in the housing in a manner complementary to the conical shape of the housing, each segment including a lip or flange at the downstream end thereof to deflect solids striking same into the main fluid stream passing through the filter while permitting fluid to pass around the lip or flange into the spacing between adjacent segments for removal from the filter. The segments may be porous to allow injection of fluid into the fluid stream to enhance dilution of solids in the stream in the region of the lip or flange.
