Problems solved by technology

At present, the air purifiers sold in the domestic market are mainly dust-removing air purifiers. Although the photocatalyst air purifiers that have appeared in recent years have the function of degrading VOC in principle, their actual efficiency is far from ideal.
[0004] After searching, there is no purification technology for catalytic degradation of harmful gases using plasma discharge in the existing literature

Embodiment Construction

[0021] The "plasma discharge catalytic air purifier" proposed by the present invention is divided into two parts, a dust removal area and a plasma discharge catalytic area. The dust removal area can be divided into two structures: single area dust removal and double area dust removal. For single-zone dust removal, the dust removal area generates plasma through corona discharge with an extremely uneven electric field, and the plasma adheres to the dust and makes the dust oriented under the action of electric field force and mechanical force (generated by the wind force in the fan or central air conditioning system) Dust is adsorbed on the electrodes; for dual-zone dust removal, the dust removal area is divided into a charging area and a dust collection area. The dust reaches the dust collection area under the action of electric field force and mechanical force, and is adsorbed by the dust collection electrodes in the dust collection area, so the dust removal efficiency of the d...

Abstract

A plasma discharge catalytic air cleaning device has a plasma discharge catalytic region, where the ions and ultraviolet ray generated by plasma discharge can stimulate the semiconductor catalyst chosen from TiO2, ZnO, ZnS, Fe2O3, CdS, CdSe, WO3 and their mixture for generating the hydroxy free radicals to degradate harmful gas, sterilize and disinfect.

Description

Technical field: [0001] The utility model relates to a plasma discharge catalytic air purifier, which belongs to the field of environmental protection and medical treatment, and particularly relates to the technical field of air purification. Background technique: [0002] With the advancement of science and technology and the development of human civilization, the air quality on which human beings depend is declining, especially the indoor air pollution is still increasing. Indoor air pollution is mainly harmful refractory organic compound pollution and microbial pollution. These pollutions can lead to various diseases such as leukemia, cancer and so on. Therefore, how to create a clean living environment is a top priority that is related to the health and even life safety of the broad masses of the people. [0003] In order to purify polluted air, people have developed various air purifiers. Indoor air purifiers are mainly divided into three types: dust-removing air pur...
