Electrostatic trapping device for fine particles based on rotating polar lines

Abstract

The invention relates to a rotary-electrode-wire-based electrostatic capturing device for fine particulate matters and solves the problems of single function, poor dust removal effect to the fine particulate matters, high energy consumption and the like in existing dust collection devices. According to the technical scheme, the electrostatic capturing device comprises a cylinder body, a motor and at least one layer of electrostatic assembly which is driven by the motor. Each layer of electrostatic assembly comprises an insulated shaft coupling and an electrified shaft connected with the insulated shaft coupling, 1-3 layers of conductive discs are arranged along the axial direction of the electrified shaft, a plurality of combined electrode wires are uniformly arranged on the conductive discs, one ends of the combined electrode wires are connected to the conductive discs and the other ends of the combined electrode wires are free ends; the combined electrode wires are composed of a plurality of braided wires and metal static wires which are crossed with one another and are bundled together, and the braided wires are made of hygroscopic cellulosic materials. The rotary-electrode-wire-based electrostatic capturing device is extremely simple in structure, low in resistance, high in efficiency, small in occupied area, light in weight, small in energy consumption and low in cost, is simple and convenient to operate, can resist corrosion and has functions of dust extraction, sterilization and demisting.

Description

technical field [0001] The invention relates to an industrial gas purification device, in particular to an electrostatic collection device for fine particles based on rotating polar lines. Background technique [0002] There are many kinds of existing industrial flue gas dust removal methods and dust removal facilities, including dry dust removal and wet dust removal. Dust removal, especially for pM2.5, pM10 and aerosols, has extremely poor capture effect. How to achieve simultaneous high efficiency, low cost, low energy consumption, and rapid separation has always been a technical problem that those skilled in the art want to solve. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems, and provide a kind of structure extremely simple, easy to operate, low resistance, high efficiency, small footprint, corrosion resistance, no fouling blockage, light weight, low energy consumption, low cost, An electrost...
