Electrostatic precipitator

Abstract

The present invention provides an electrostatic precipitator, comprising an electrically charged unit and an electrostatic dust collection unit, and the electrostatic precipitator is characterized in that: the electrostatic dust collection unit adopts a spacer made from a metal material or an inorganic conductive material to keep a certain distance between dust collection plates and sheets. The air contact surface of the dust collection plates and sheets is made from an insulation material, so that adjacent dust collection plates and sheets may not be conducted. The spacer can be prepared by stamping molding of a metal plate such as an aluminum plate and a copper plate, also can be prepared by die-cast molding, metal bar pressing molding, and other manners, and an inorganic conductive material also can be used. Compared with a traditional electrostatic precipitator, electrostatic precipitator has the advantages of high efficiency, no arc discharge, low ozone and higher security.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an electrostatic dust collector. Background technique [0002] Most traditional electrostatic precipitators use metal plates as dust collection materials, and insulating materials such as plastics are used as spacers between the metal plates to maintain the distance between the metal plates and increase the overall rigidity of the dust collector. The more common method of the spacer is a comb-shaped plastic clip, which on the one hand clamps each metal plate, and on the other hand keeps the distance between each metal plate unchanged. [0003] This method is simple in process, but there are the following outstanding problems: [0004] 1) There must be dust accumulation in the gap between the spacer and the metal plate. When the air is humid, it is easy to cause a short circuit or violent discharge on the adjacent dust collecting plate; [0005] 2) After the dust collector is cle...

AI Technical Summary

Problems solved by technology

[0004] 1) There must be dust accumulation in the gap between the spacer and the metal plate. When the air is humid, it is easy to cause a short circuit or violent discharge on the adjacent dust collecting plate;

[0005] 2) After the dust collector is cleaned, the gaps of the spacer are easy to store water, which will lead to short circuit and violent discharge;

[0006] 3) In actual use, it is common for the spacer to be burned by the discharge between the plates or even catch fire
