ELECTRIC FILTER CORONA ELECTRODE ELEMENT Russian patent published in 2023 - IPC B03C3/41 

FIELD: gas cleaning.

SUBSTANCE: devices for cleaning gases in various industries. The corona electrode element with fixed corona discharge points includes a tape body with a profiled central part and flat edge sections notched at an angle to the end lines to form triangular tips bent away from the flat edge sections. The internal radii between the triangular tip and the flat edge section and between the profiled central part and the flat edge sections are at least 1.25 times the thickness. The distance from the base of the triangular tip to the profiled central part is at least 2 thicknesses. The angle between the end line and the side of the triangular tip is between 10° up to 45°.

EFFECT: increased reliability of corona elements with reduced corona ignition voltage when exposed to repeated shock loads necessary to remove dust deposits from them.
