Cleaning contaminated air from grinding of polishing equipment - includes passing air through duct into which moistened air is tangentially injected, feeding to vertical centrifuge and then washing vessel, etc.

摘要

Contaminated air is passed through a duct into which moistened air is injected tangentially to produce a swirling action. The air enters a vertical centrifuge where solid material is deposited at the bottom, the partly cleaned being removed through a vertical pipe to enter a vertical washing vessel contg. a structure of pockets. Clean air is extracted at the top by a duct connected to a suction unit and liquid falls to the base to pass to a microfilter, the fine solid material being discharged into a collector. At the tangential spray zone at the inlet duct, the air temp. and saturation are regulated by a control system. The process is interrupted to prevent explosion. USE/ADVANTAGE - Used to clean contaminated air from grinding or polishing equipment.
