Problems solved by technology

These optimization results only reduce the corona inception voltage of the cathode line to a certain extent and improve the discharge capacity, but do not fundamentally solve or optimize the problem of the uniformity of charge distribution in the dust removal space, so the cost reduction and efficiency increase are not obvious

Abstract

The invention discloses a cathode ray structure based on bionics, a discharging system and a method. A supporting piece is included, a plurality of discharge electrodes are arranged on the supportingpiece in the circumferential direction, each discharge electrode comprises a base connected with the supporting piece, discharge tips with different lengths are arranged on each base in the circumferential direction in a staggered manner, and a center discharge tip is vertically arranged at the middle portion of each base; the length of each center discharge tip is larger than the lengths of the corresponding discharge tips arranged on the corresponding base in the circumferential direction, the center discharge tip is used for reducing the distance between the cathode ray structure and an anode, the formed electric field intensity enables the driving force of an electric field obtained after smoke charging to be high, and the discharge tips arranged on the bases in the circumferential direction are used for increasing spatial distribution homogeneity of electric charge, and therefore the smoke in the space can be better charged.

Description

technical field [0001] The invention relates to the technical field of electrostatic precipitators, in particular to a cathode wire structure, discharge system and method based on bionics. Background technique [0002] The wet electrostatic precipitator solution is the main technology to achieve ultra-low emission of flue gas and dust after wet desulfurization such as limestone-gypsum method and ammonia method. Improving the approach speed of dust in the dust collector is the key method to reduce the equipment height and cost of the dust collector. Usually, the focus of increasing the approach speed of soot is to increase the driving force of soot moving to the anode. The method includes: (1) reducing the corona inception voltage of the cathode line. (2) Increase the voltage between the cathode and anode, and the driving force of the lateral motion of the soot will increase under the premise of the same charge; (3) Improve the uniformity of the discharge charge of the catho...
