ABSTRACT:
A dual purpose dust-collecting device consisting of an upright cylinder tapered at the lower end to form a settling chamber containing water. An inner cylinder formed with a plurality of circumferentially spaced tangential inlets is secured to the inside of the cylinder to define therewith an annular gas stream passage. A swinging inlet damper mounted in a manifold having an upper tangential gas outlet and a lower tangential gas outlet leading to the upper and lower ends of the cylinder respectively is employed for selectively admitting gas from the manifold inlet to the upper end of the cylinder or to the annular gas passage. When dirty gas enters the annular passage under the action of an exhaust fan mounted atop the cylinder, a whirling gas stream will be created therein and forced through the tangential inlets into the inner cylinder wherein a rapidly rotating whirlpool will be created which causes separation of particles from the dirty gas stream. When dirty gas is admitted to the upper end of the cylinder, the gas will be induced to spiral downward by an inverted cone depending from the top of the cylinder and cause the water in the cylinder to become a rising whirling water curtain whereby particles separated from the dirty gas stream by centrifugal force settle to the bottom of the settling chamber while the cleaned gas is discharged through the cone by the fan. The device may serve as a conventional dry cyclone dust collector if water is not used.
