Multilayer electrostatic air filter plate

Abstract

The invention provides a multilayer electrostatic air filter plate which is composed of more than two parallel dust collecting plates, wherein each dust collecting plate is composed of a metal plate and an insulating electret material combined with the metal plate; the electrodes connected with the adjacent two dust collecting plates have opposite polarities; a plurality of filtered air channels are formed in each dust collecting plate and perpendicular to the dust collecting plate. Air passes through a plurality of electrostatic fields, the adjacent two electrostatic fields have opposite polarities, and the polarization effect on the air is different. The particles repeatedly polarized are more easily adsorbed by the electrostatic fields. Thus, the air is filtered through multilayer electrostatic fields, and the purifying effect of air is better.

Description

technical field [0001] The invention relates to an electrostatic air filter plate, in particular to a multi-layer electrostatic air filter plate. Background technique [0002] In the air that is constantly polluted in real life, fine particles, especially particles with a particle size less than or equal to 2.5 microns (PM2.5), cause great harm to human health; in order to improve the air in the living room or in the cab of a car, There are many devices that use the adsorption function of the electrostatic filter plate to achieve clean air. The electrostatic filter plate itself will absorb a lot of dust in the process of filtering air, but how to clean the filter plate has always been a technical problem that plagues the industry; if the gap between the filter plates is large, sometimes it is convenient to clean, but The filtering effect is reduced again. The patent of authorized announcement number CN202893510U discloses a kind of dust collecting board; The patent of auth...
