DEVICE AND METHOD FOR COLLECTION OF AEROSOL PARTICLES AND THEIR CONCENTRATION DEFINITION Russian patent published in 2010 - IPC B01D47/06 

FIELD: mechanics.

SUBSTANCE: invention is intended for collection of aerosol particles and their concentration definition. The device contains a cyclone consisting of a turbulence chamber with a tangential intake nipple and a deposition chamber, the sorbent liquid reservoir, the recirculating sorbent liquid collector and a return pipe for delivery of the sorbent liquid collected in the collector to the reservoir. The intake nipple contains two cylindrical channels positioned vertically one under the other and having a common conic nozzle on the inlet side. The reservoir is represented by a detachable cartridge mounted on the cyclone outer wall. The method includes stages of delivery of clean sorbent liquid into the cartridge, collection of aerosol particles with the sorbent liquid, sampling the sorbent liquid contained in the cartridge, contamination level measurement, drain of sorbent liquid from the cartridge when the contamination level exceeds the value preset and replenishment of the cartridge with a new portion of clean sorbent liquid. The stage of aerosol particles collection includes mixture of sprayed sorbent liquid and air in the inlet nipple and delivery of the mixture into the cyclone, catching aerosol particles with a sorbent liquid film and collection of the letter, delivery of the collected sorbent liquid into the inlet nipple for re-mixture with air.

EFFECT: improved efficiency of aerosol particles collection and reduced loss of recirculating sorbent liquid.
