Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic dust removal, in particular to an electrostatic dust collector equipped with a self-cleaning device. Background Art

[0002] Electrostatic precipitation is a method for removing dust from gases. It works by first generating a high-voltage DC electric field using the principle of ionizing electrode corona discharge. This ionizes gas molecules in the air, generating a large number of electrons and ions, which charge dust particles in the surrounding dirty air. The charged dust-laden gas then passes through the dust collection assembly, where it is adsorbed by the oppositely charged dust collecting plates, achieving dust collection and purifying the polluted air. Simultaneously, the high voltage captures bacterial particles, instantly conducting electricity and breaking down the protein-based cell walls, thus also providing a sterilizing and disinfecting effect.

[0003] The advantage of electrostatic dust removal devices based on this working principle is that they have no consumable air filter elements. They are widely used in space purification and disinfection in smart buildings and public places, and are also used for household dust removal and sterilization.

[0004] However, after a period of use, dust is easily accumulated on the dust collecting plates of the filter element, which affects the dust removal efficiency and even causes a series of safety problems such as sparks and electric creepage. Therefore, the dust collecting plates of the electrostatic dust collector need to be manually cleaned and maintained regularly. At present, the industry mainly uses water washing as a cleaning method for high-voltage electrostatic dust collectors. After water washing, they need to be dried or wait for them to be thoroughly dry before they can be installed and used to avoid safety problems after turning on the power. This maintenance and cleaning process requires regular disassembly and operation in a professional and correct manner. It is more troublesome, and multiple disassembly and cleaning can easily damage the dust collecting device, resulting in increased maintenance costs. The existing electrostatic dust removal device also has low cleaning efficiency during the cleaning process. The upper and lower surfaces of each plate need to be thoroughly cleaned. In addition, in order to increase the dust removal effect, the span of the dust collecting plate is large, which can easily cause the middle of the plate to sag, affecting the dust removal effect.
