CORONA ELECTRODE OF ELECTRIC FILTER Russian patent published in 1997 - IPC

FIELD: gas purification. SUBSTANCE: corona electrode made of polymer material consists of carrying part made of multiple-channel plate, its axes being parallel to each other, and corona part. The latter is continuation of at least one of longitudinal edges of multiple-channel plate, shaped as a whole with carrying part and made in the form of tape with fixed discharge points. Ratio of width of carrying part to that of corona part is (0.8-1.0): 1. Corona electrode may be made of n interconnected multiple-channel plates located in intersecting planes. Intersection axis of planes is parallel to axes of channels. Intersection angles of planes are equal to each other and range from 10 to 90 deg., whereas n is at least 2. EFFECT: improved structure of filter. 2 cl, 3 dwg, 2 tbl
