A Coulomb anode plate and a Coulomb anode plate dedusting system

Abstract

The invention discloses coulomb electrode plates and a coulomb positive plate dust removal system. The coulomb positive plates comprises positive plate bodies, wherein each positive plate body comprises an arc-shaped convex section, arc-shaped concave sections and side edge sections; the arc-shaped convex sections are in symmetrical arrangement by using the arc-shaped convex section as the symmetry center; the two ends of the arc-shaped convex section are connected with the arc-shaped concave sections; the opening directions of the arc-shaped convex section and the arc-shaped concave sectionsare opposite; the ends, far away from the one ends connected with the arc-shaped convex section, of the arc-shaped concave sections are connected with the side edge sections; the ends, far away from one ends connected with the arc-shaped concave sections, of the side edge sections are arranged in a way of facing the opening direction of the arc-shaped concave sections. The coulomb positive plate and the coulomb positive plate dust removal system have the effects of improving the dust removing efficiency and improving the positive plate heat radiation performance and anti-oxidization performance.

Description

technical field [0001] The invention relates to the technical field of Coulomb electric dust removal, in particular to a Coulomb anode plate and a Coulomb anode plate dust removal system. Background technique [0002] During the operation of the coal pyrolysis device, a large amount of dust is mixed with the pyrolysis gas, which seriously affects the subsequent process. Therefore, advanced dust removal equipment is needed to remove the dust in the flue gas. One of the more effective methods of collecting particles in flue gas is electrostatic precipitator. [0003] The method of electrostatic precipitator to separate suspended dust particles in gas mainly includes four steps: ionization of gas, charging of suspended dust particles, movement of charged dust particles to electrodes, and deposition of charged dust particles on electrodes. The gas is first ionized under the high-voltage electric field, and the dust suspended in the flue gas is charged, and then the gas is pass...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: the anode plate in the electrostatic precipitator is usually a conductive straight steel plate, and when the flue gas produced by coal pyrolysis passes through the steel plate, the dust adsorbed on the steel plate by Coulomb force will be due to The blowing force of the flue gas flow on the dust makes the dust fall from the steel plate again, which makes the dust removal efficiency lower
