DEVICE FOR CLEANING AIR OF FLYING VEHICLE PRESSURE CABIN FROM DUST Russian patent published in 1995 - IPC

FIELD: air-conditioning systems. SUBSTANCE: air flow comes to first cleaning stage on side of inlet branch pipe where it is cleaned of coarse particles of dust passing through cyclones getting twisted in screw blades; coarse particles of dust interact with metal rods, coagulate and accumulate in chamber between partitions of first stage wherefrom they are evacuated through dust discharge branch pipe. Then flow of air enters second stage of cleaning replaceable casette; in replaceable casette air is finally cleaned of dust and is fed to pressure cabin. EFFECT: enhanced efficiency. 5 dwg
