GAS DYNAMIC APPARATUS FOR REMOVING DUST FROM EMISSIONS Russian patent published in 1995 - IPC

FIELD: cleaning gases. SUBSTANCE: apparatus has modules of hydrodynamic concentrators of dust contaminants made up as axially symmetrical assembly of modules connected in parallel. The cleaned gas is directed to the common discharging collector. The outlet ends of the modules of the dust concentrators are connected to the common dust collector through dust conducting pipes and couplings. The space of the dust collector is positioned above the exit section of dust discharging pipes and separated into two parts by the labyrinth filter. The space above the filter is, in turn, connected with the inlet of the additional dust concentrator. The outlet of the additional dust concentrator is connected with the common discharging collector through the additional fan. The dust discharging pipe of the additional dust concentrator is connected with the additional chamber of the common dust collector. EFFECT: enhanced efficiency. 1 dwg
