Abstract

The invention belongs to the technical field of gas purification and relates to an electric purifying component and an air purifier containing the same. The electric purifying component comprises a charge part and a dust collecting part, wherein the dust collecting part comprises a dust collecting electrode, and the dust collecting electrode comprises a dust collecting electrode main body and a porous layer arranged on the surface of the dust collecting electrode main body; or the material of the dust collecting electrode is a porous conductive material. By arranging the porous layer on the surface of the dust collecting electrode main body or directly adopting the porous conductive material to make the dust collecting electrode, the dust collecting electrode has a porous structure, so that the use period can be prolonged. Besides, by arranging a catalyst layer between the dust collecting electrode main body and the porous layer or directly arranging the catalyst layer on the surface of the dust collecting electrode, the dust collecting electrode also has the function of absorbing gaseous pollutants; and by reasonably selecting a corona generating electrode material and combining power supply voltage control and power supply time control, ozone generating quantity can be reduced.

Description

technical field [0001] The invention belongs to the technical field of gas purification, and in particular relates to an electric purification component and an air purifier comprising the same. Background technique [0002] The existing air purification technology mainly adopts the filtering method. Due to the objective existence of the filter mesh, suspended particles smaller than the diameter of the mesh can still pass through the filter and cannot achieve efficient purification. In addition, the filtration technology also has large wind resistance and secondary Pollution, secondary consumption caused by frequent replacement of filter screens and other defects. With the rapid development of air purification technology, the electrostatic precipitator technology that can solve the above-mentioned drawbacks emerged as the times require, and was quickly favored by researchers. [0003] Electrostatic precipitator technology uses a strong electric field generated by high voltag...
