ELECTRIC FILTER WITH SELF-CENTERING CORONA-FORMING ELEMENTS Russian patent published in 2012 - IPC B03C3/41 

FIELD: process engineering.

SUBSTANCE: invention relates to electric cleaning of gases of suspended solid and fluid particles in heat power engineering, chemical industry, production of construction materials, metallurgy, etc. Proposed filter consists of casing, precipitation and corona-forming electrodes and electrode shakers. Corona-forming electrodes has different-length-and-cross-section-needles. Note here that long needles have smaller cross-section than that of short needles.

EFFECT: higher quality of gas cleaning due to better centering.
