ABSTRACT:
An apparatus for collecting airborne particles includes a cyclone into which external air and an absorbing liquid are sprayed to absorb the airborne particles in the external air with the absorbing liquid, a reservoir in fluid communication with the cyclone and which stores the absorbing liquid to be sprayed into the cyclone as an absorbing liquid film, a collector in fluid communication with the cyclone and which collects the absorbing liquid film from the cyclone, and a feedback pipe in fluid communication with the collector and the reservoir and which transports the absorbing liquid film collected in the collector to the reservoir.
