ELECTRIC FILTER CORONA-FORMING ELECTRODE ELEMENT Russian patent published in 2004 - IPC

FIELD: electric cleaning gases from dust; heat-power engineering; chemical industry; manufacture of building materials; metallurgy. SUBSTANCE: corona-forming element has band-shaped body with central profiled part. Body includes flat edge sections which are notched from one point over inclined lines directed to different sides at acute angle relative to end line of edge section, thus forming three triangular end-pieces. Points of notch are smoothly distributed over length of body and on both edge sections. End-pieces adjoining end lines of edge sections of body are bent from plane of edge section and third end-piece formed by two inclined lines remains in plane of body and its angle between inclined lines exceeds angle of bent end-pieces. EFFECT: enhanced operational efficiency due to use of corona-forming electrode at reduced ignition voltage and high current of corona. 5 dwg
