Electrostatic dust removal is one of the methods of gas dedusting. The dust-containing gas is electrically separated when passing through a high-voltage electrostatic field, and after the negative combination of the dust particles and the negative ions, the surface of the anode is discharged and deposited. Used in the metallurgical, chemical and other industries to purify gases or recover useful dust particles. A dust collecting method for ionizing a gas by an electrostatic field to electrically adsorb dust particles to the electrode. In a strong electric field, air molecules are ionized into positive ions and electrons, and electrons encounter dust particles in the process of the positive electrode, so that the dust particles are negatively charged and absorbed to the positive electrode to be collected.

Of course, through technological innovation, there is also a way of collecting dust using a negative plate. In the past, it was often used in coal-fired factories and power stations to collect coal ash and dust from flue gas. Metallurgy is used to collect oxides of tin, zinc, lead, aluminum, etc., and there are also dust sterilization products that can be used in households.
　　 Technical characteristics
　　 The ordinary purifier uses filter paper to filter the dust in the air, which is easy to block the filter hole, and the dust accumulates more, which not only has no sterilization effect, but also easily causes secondary pollution. The electrostatic precipitator technology has the following advantages:
　　 (1) High dust removal efficiency;
　　 (2) can purify a large amount of gas;
　　 (3) The particle size range that can be removed is wide;
　　 (4) It can purify high dusty flue gas;
　　 (5) The structure is simple, the air flow speed is low, and the pressure loss is small;
　　 (6) Energy consumption is lower than other types of dust collectors;
　　 (7) The electrostatic precipitator can realize microcomputer control and long distance operation.
