ELECTROFILTER Russian patent published in 1997 - IPC

FIELD: filtration technics. SUBSTANCE: invention relates to dedusting of process and aspiration gas releases. Electrofilter contains two separate box-like casings enclosing block of precipitation electrodes in the form of horizontally arranged overflow air duct provided with sets of dust-intake windows on the both ends, disk precipitation electrodes being disposed parallel to each other between dust-intake windows. Dusted gas flow passes through active zone of corona discharge in the first dedusting step and, through overflow air duct, gets into the second dedusting step and therefrom, through discharge gas duct, into atmosphere. Settled layer due to continuous rotation of precipitation electrode block assisted by brush knife is collected in bunker - dust-catcher and is periodically removed by dust discharge mechanism. EFFECT: enhanced dedusting process. 2 cl, 3 dwg
