Abstract
A dirty gas inlet configuration for a cyclone-type particulate matter gas separator device has two annular concentrically disposed converging dirty gas channels. The outer annular channel has a plurality of gas flow directing vanes disposed therein to impart a spinning or whirling motion to a dirty gas stream passing into the separator device through the outer annular channel from outside the separator device. The inner annular channel has an adjustable dirty gas inlet for varying the volume rate of flow of dirty gas passing into the separator device through the inner annular channel from outside the separator device. The dirty gas streams exiting the outer and inner annular converging channels are mixed together in an annular mixing chamber located downstream from and coaxially disposed with the outer and inner annular channels. While mixing together, the whirling gas stream from the outer channel imparts a whirling motion to the dirty gas stream from the inner annular channel. The mixed whirling gas stream then exits the annular mixing chamber and moves downstream in the gas separator device for further processing to separate particulates therefrom.
