METHOD OF AERODYNAMIC CLEANING OF AIR MEDIA OF DUST, AERODYNAMIC DUST COLLECTING MODULE AND PLANT FOR AERODYNAMIC CLEANING OF AIR MEDIA (VERSIONS) Russian patent published in 1997 - IPC

FIELD: dedusting of air. SUBSTANCE: method consists in delivery of dustladen air to cavity of aerodynamic dust concentrator where dust separating unit is coaxially mounted. Dust separating unit is made in form of profiled round or linear members converging in form of cone or wedge, evacuation of air through lateral gaps between members, layer by layer, turning jets in each layer, repeated quantized transfer of dust particles from layer to layer within gaps followed by direction of air flow to hopper at reduced pressure; air entering the hopper is returned to inlet portion of concentrator through filter. Aerodynamic dust collecting module includes cone-shaped or wedge-shaped aerodynamic dust separating unit whose inlet is connected with taper air intake and outlet is connected with dust removal unit including dust removal head and impact disturbance device. Three versions of plant for aerodynamic cleaning of air media are proposed; plant includes dust collecting module-hopper with dust removal branch pipe inserted in it, labyrinth filter and gas drawing unit. EFFECT: enhanced efficiency of cleaning. 11 cl, 37 dwg
