Description

technical field [0001] The invention relates to a vertical multi-stage double-drive coupling electrostatic precipitator, which is used for purifying dust-containing gas discharged in industrial processes. Background technique [0002] Coal-fired power generation, metallurgy, petrochemical, mining and many other industrial production processes will emit various dusty gases, such as flue gas, tail gas, waste gas, etc. Dusty gas refers to the gas containing a certain concentration of solid dust particles or particles, and its particle size ranges from a few hundred microns to several microns, even reaching nanometers. Due to the different physical and chemical characteristics of the solid particles carried by the dusty gas, the hazards caused are also different, which not only affects industrial production, but even causes environmental pollution and endangers human health. Electrostatic precipitators are widely used in the purification of dusty gases in industrial processes. ...

AI Technical Summary

Problems solved by technology

However, there are mainly the following common problems at present, such as the unreasonable arrangement of electrodes and charging space during the charging process of dust particles, resulting in limited effective charging area, and the phenomenon of shielding in periodic local areas, which makes the charging effect of dust particles poor. It directly affects the dust removal efficiency; for another example, it is difficult for traditional electrostatic precipitators to remove fine particles; in addition, the secondary dust during the dust removal process, as well as the dust hardening phenomenon that exists during equipment cleaning and maintenance, are difficult to deal with and easily cause secondary dust. secondary pollution
