ABSTRACT:
A dust contaminated air stream enters a cyclone-type dust separator having a curved outer wall and follows a path that spirals downwardly and inwardly. The primary air stream, which occurs during the first revolution, is separated from the subsequently occurring secondary air stream by an inner wall or baffle in the form of a curved member extending inwardly into the separator approximately one-half revolution along a path generally paralleling said air stream and defined by a continuously decreasing radius. The inner wall terminates at the dust separation point, which is also the turning point of the air stream. The inner wall and corresponding portion of the outer wall converge slightly to cause an acceleration of the primary air stream. A discharge cylinder extends downwardly through the top of the separator into the interior thereof and has a lower edge or inlet at a point in substantially the same horizontal plane as the above-mentioned turning point of the air stream.
