AN APPARATUS FOR PICKING UP AND COLLECTING PARTICULATE MATERIAL

摘要

An apparatus (10) to separate a particle containing fluid such as dust laden air uses a Coanda blowing slot (14) to entrap particles into a recirculating fluid stream, and strips the particles out of the fluid stream in a separati on chamber (31, 16) preferably using a vortex system. The apparatus can be a ze ro emission apparatus making it suitable in areas where conventional vacuum cleaners are inappropriate.
