ABSTRACT:
A scrubber for use with a cyclone collector having a vortex finder through which the collected exhaust gas containing fine particles flows vertically in a rapidly swirling vortex. As the vortex exits from the vortex finder in the cyclone collector, it passes radially outwardly through a parallel plate diffuser into a scrubber housing which has a diameter substantially larger than that of the vortex finder and which extends down over the exit end of the vortex finder. As the vortically flowing exhaust gas vortex passes through the parallel plate diffuser, still having a high tangential velocity, a liquid spray is introduced into the larger diameter vortex to trap fine particles in the exhaust stream, with a baffle means disposed over the end of the vortex finder blocking the entry of the liquid spray into the vortex finder. The liquid droplets and the fine particles trapped therein impinge on the suface of the scrubber housing, due to the relatively great mass of the liquid droplets, and then run or drop down onto the bottom wall of the housing and on out through a drain opening. The cleansed exhaust gas continues to swirl upwardly through the scrubber housing and is discharged through an exhaust duct.
