Problems solved by technology

[0004] However, the above two methods only optimize the local geometric structure size, and do not fundamentally change the type of the existing cathode line to improve the discharge capacity and space charge uniformity of the electrostatic precipitator. For low-concentration smoke pollutants ( Inlet dust concentration is less than or equal to 30mg / Nm 3 ) has a limit in removal efficiency, resulting in high cost and poor economy of the wet electrostatic precipitator system

Abstract

The invention discloses a cathode wire device and an electric precipitator for removing low-concentration smoke pollutants, which include a conductive splint, and the conductive splint clamps a plurality of discharge electrodes made of non-metallic conductive materials. The present invention adopts non-metallic conductive material as the discharge electrode of the cathode line, adopts non-metal discharge electrode, for example, a bundle of carbon fiber filaments is non-rigid, and each fiber filament will have a certain repulsion during the discharge process, so that the ions generated during the discharge process more evenly distributed.

Description

technical field [0001] The invention relates to the technical field of electric precipitators, in particular to a cathode line device and an electric precipitator for removing low-concentration soot pollutants. Background technique [0002] Wet electrostatic precipitator is used in power plants, iron and steel plants, etc. to achieve ultra-clean low-concentration soot 3 ) and near zero (less than or equal to 1mg / Nm 3 ) One of the main technologies of emission standards. The discharge system of the wet electrostatic precipitator is based on the discharge system of the dry electrostatic precipitator, especially the cathode line adopts RS prickly type, acupuncture type or other traditional conventional types. [0003] Under the same operating conditions (operating voltage, cathode and anode length), improving the efficiency of the electrostatic precipitator is to improve the discharge capacity of the cathode and anode discharge system on the one hand, and to increase the unif...
