Cleaning device for contaminated air comprises use of finely dispersed liquid, high speed rotor and rotated cylindrical filter wall to improve capture of particulates and to centrifugally separate liquid

摘要

A housing (1) contains a cylindrical chamber closed at one end, with contaminated air entering at the other end via a duct (5). The closed end contains a mechanical break-up head (100) for dispersion of liquid droplets and for promoting high turbulence. The chamber and liquid disperser are rotated at high speed causing liquid and wetted particles to be thrown outwards on to the filter walls. A housing (1) contains a cylindrical chamber defined by a cylindrical wall (17). The chamber is closed at one end and at the other end contaminated air enters via a duct (5) in the housing. The closed end contains a mechanical break-up head (100) for dispersion of liquid droplets and for promoting high turbulence. A fluid, preferably water, may be introduced into the air flow via inlets (23) at the air inlet duct. The chamber and liquid disperser are rotated at high speed causing liquid and wetted particles to be thrown outwards on to the filter walls, where the liquid is coalesced and separated by flowing down the inside of the housing wall to the outlet (4) and the cleaned air is discharged through the perforated bottom (3) of the housing.
