Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0013] Such as figure 1 As shown, a multi-stage plasma air cleaner includes a housing 1, air 2, fan 3, filter layer 4, dielectric barrier discharge reaction system 6, first air inlet 11, third air outlet 12, and support plate 13 , ozone decomposition catalyst 14, purified gas 15. The dielectric barrier discharge reaction system is composed of a high-voltage electrode 8 , a ground electrode 9 , an insulating dielectric tube 7 , and a composite catalyst 10 . The air 2 containing volatile organic compounds (VOCs) is conveyed under the power of the fan 3, and after being dedusted and purified by the filter layer 4, it passes through the first air inlet 11 according to the figure 2 According to the connection mode, it enters the dielectric barrier discharge reaction system 6 of each stage, VOCs are oxidized and degraded into carbon dioxide and water by the dielectric barrier di...

Abstract

The invention provides a multistage plasma air purifier. The multistage plasma air purifier is composed of a draught fan, a shell, a filtering layer, multiple stages of medium blocking and discharging reactors and an ozone decomposing catalyst. The multiple stages of medium blocking and discharging reactors and the ozone decomposing catalyst are core parts of the multistage plasma air purifier. According to the purifying principle, after particles are removed from air containing volatile organic compounds (VOCs) through the filtering layer; the VOCs are subjected to oxidative degradation through the multiple stages of medium blocking and discharging reactors to become carbon dioxide and water; ozone and not completely-decomposed organic matter which are generated by the medium blocking and discharging reactors are decomposed by the ozone decomposing catalyst; and final indoor air quality reaches the purification requirement.

Description

technical field [0001] The invention relates to the technical field of an air purification device, in particular to a multi-stage plasma air cleaner, which can be used for indoor air purification. Background technique [0002] With the development of my country's economic level, great changes have taken place in the indoor environment of people's lives. Various chemical materials such as coatings, paints, and adhesives used in the decoration and decoration process release a large amount of volatile organic compounds into the room. It can cause headaches, insomnia and other reactions, and reduce the immune function of the body, which is very harmful to the human body. Therefore, it is of great significance to research and develop VOCs purifiers and strive to improve the indoor air quality. [0003] At present, there are many types of indoor air purifiers on the market, but most of them have some defects. Filter purifiers can only remove particulate matter in the air, but can...
