The invention relates to the technical field of
air filter products, in particular to an
electrostatic precipitation filter which is used for
trapping particulate matters in air efficiently and has an integrated structure and a polarization process for the
electrostatic precipitation filter. A main body of the
electrostatic precipitation filter is formed by overlaying a plurality of
layers of pore plates, wherein array holes through which the air passes are formed in the pore plates integrally; the pore plates are micro-foamed and made of a plastic material added with a polarization reinforcing material, a negative
ion emitting material and a magnetic material; closed conducting films for applying high-
voltage electric fields are arranged on upper and lower surfaces of each layer of pore plate, and
ion emitting devices are arranged in one or more of
layers of pore plates; and a high-
voltage power supply for supplying power to a high-potential
electrode and a low-potential
electrode is encapsulated on the lateral surface of an overlaid structure, the overlaid structure and the high-
voltage power supply are encapsulated in an outer frame of a protective structure integrally, and the outside of the outer frame is powered by low-voltage
direct current or a mains supply. The electrostatic
precipitation filter is processed by an on-line polarization technology to form a practical product. Due to the adoption of the technical scheme, the particulate matter filter can eliminate interelectrode sparking and
electric shock hidden troubles, is easy to clean, low in wind resistance and high in efficiency, has long service life, can be recycled and is suitable for household and industrial
air purification devices.
