MINI-CYCLONE BIOCOLLECTOR AND CONCENTRATOR

摘要

Multiple mini cyclones operating in parallel in radial geometry or in a bipolar or unipolar longitudinal design to reduce the size and velocity of a n airstream containing large and small particles through the cyclones while maintaining the same flow rate as compared to one large cyclone. A blower or vacuum pump draws the airstream into the cyclones through tangential radial inlets (40) and the airstream swirls downwardly. A portion of the airstream carrying the small particles reverses direction and leaves the cyclones through an upper vent assembly (50). A remaining portion of the airstream carrying the large particles continues downwardly as well as outwardly towar ds walls of the cyclones; the airstream exits at a bottom apex while the large particles stick to the walls. Liquid is pumped into the cyclones from a liqu id reservoir (10) to flush the large particles into the reservoir (10). The liquid is continuously recirculated and can be monitored for toxic microorganisms.
