TWO-ZONE ELECTRIC FILTER FOR CLEANING OF GASES (VERSIONS) Russian patent published in 1996 - IPC

FIELD: environmental control. SUBSTANCE: invention is meant for electric gas cleaning in low-volume dust technological processes and in cleaning of aerosols. Filter has charge chamber in the form of parallel grounded plates between which corona electrode is placed in symmetry plane perpendicular to longitudinal axis. Precipitation chamber includes system of flat parallel electrodes one of which is positioned in symmetry plane. In agreement with one version precipitation electrodes nearest to symmetry plane are located at greater distance from electrode lying in symmetry plane than distance between pairs of other adjacent electrodes. In compliance with another version electrode in symmetry plane and precipitation electrodes nearest to symmetry plane have smaller length than adjacent precipitation electrodes. EFFECT: improved cleaning efficiency of electric filter. 7 cl, 3 dwg
