Abstract

The invention provides an electrostatic precipitator which comprises a multi-stage dust remover, wherein the multi-stage remover at least consists of a fine particle dust remover, the fine particle dust remover consists of a plurality of pole plates, a plurality of wire meshes and a plurality of high-voltage polar lines, wherein the wire meshes and the high-voltage polar lines are arranged between every two adjacent pole plates and are alternately distributed with preset intervals. The embodiment of the invention can increase the chargeability of particles by corona wind and friction and reinforce the inertia capture by utilizing the acceleration and deceleration effect of the corona wind and the Brownian movement of the particles among the dense meshes, and the electrostatic force capture can also be enhanced even in smaller mesh gaps. Therefore, under multiple actions, the embodiment of the invention can greatly increases the desorption efficiency of the electrostatic precipitator to inhalable particles especial for micronano particulate matters.

Description

technical field [0001] The invention relates to the technical field of industrial dust removal, in particular to an electric dust removal device based on enhanced diffusion and capture. Background technique [0002] Coal is the main energy source of my country's industrial production, and it will still occupy a dominant position for a long time in the next few decades. The gas emitted by combustion devices in industrial production such as power generation, metal smelting, and cement manufacturing often contains a large amount of particulate matter. These particles are dispersed in the air and spread widely, seriously polluting the environment. Particular particles with very small particle size (for example <2.5 μm) can enter the human body from the respiratory tract. Because the surface of these fine particles is easier to accumulate a large amount of heavy metals, it is very harmful to human health. [0003] Due to the characteristics of concentrated separation force,...
