Combined electrostatic dust separator

Abstract

A combined electrostatic dust separator for removing the nanoparticles is composed of the first high-voltage DC discharging electric field connected to harmful fume pipeline for pre-collecting dust, the second high-voltage pulse discharging electric field for electrically charging the dust particles, and the third and fourth high-voltage DC discharging electric fields for coagulating and collecting dust.

Description

technical field [0001] The invention relates to a dust collector, in particular to a compound electrostatic dust collector. Background technique [0002] Coal is the main source of electricity in our country. In the foreseeable next few decades, coal-fired thermal power generation will occupy a dominant position in my country's power industry for a long time. This long-term energy structure that relies on coal-fired power generation has caused serious environmental pollution. The smoke and dust emitted by coal-fired power plants is one of the important sources of inhalable particulate matter in the atmosphere. Inhalable particulate matter, especially particulate matter (PM2.5) with a diameter of less than 2.5 microns is an important pollutant affecting the air quality of our country. The harm is huge and has attracted widespread attention from the international community. [0003] At present, most power plants in my country use electrostatic precipitators (ESP) to collect ...
