Description

technical field [0001] The invention belongs to the field of air purification, in particular to an air purification device for treating pollutants. Background technique [0002] With the rapid development of modern industry and urbanization, people's living standards have been improved to varying degrees, and the requirements for high quality of life are getting higher and higher. However, the surrounding environment where people can survive is deteriorating day by day, especially It is air pollution, including indoor air pollution. According to the survey, everyone spends at least half of their time in the indoor environment on average. Among them, the elderly, children, pregnant women and patients spend longer indoors and have higher requirements for air quality. . [0003] Since the indoor air treatment method is very different from the industrial waste gas treatment method, it is required to be carried out under normal temperature and pressure, so advanced oxidation tec...

AI Technical Summary

Problems solved by technology

[0003] Since the indoor air treatment method is very different from the industrial waste gas treatment method, it is required to be carried out under normal temperature and pressure, so advanced oxidation technology has become a commonly used method, and the more commonly used methods are photocatalytic technology and adsorption filtration method. And plasma method, for photocatalytic technology, under the irradiation of ultraviolet lamp, photocatalyst can decompose volatile harmful gas into harmless small molecular gas, but because the concentration of volatile harmful gas in indoor air is low, using light The removal effect of the catalytic form is not ideal; the adsorption filtration method mainly uses activated carbon and molecular sieve to filter the pollutants to achieve the purpose of purification, but the adsorption materials have a certain adsorption capacity. After the maximum adsorption capacity of the adsorption material, the adsorption material will lose its adsorption function, and it will easily cause secondary pollution to the air.

Most of the current mainstream air purifiers use adsorption filters to purify the air, so customers must frequently replace and clean the filters, which is cumbersome

[0004] The plasma method is to treat air pollutants through plasma discharge. The plasma suitable for indoor air treatment is classified according to the discharge method. There are two main types, one is corona discharge, the other is dielectric barrier discharge, corona discharge It is generally suitable for the treatment of particulate matter and microorganisms. Due to the weak discharge, the treatment effect on volatile organic compounds is average. The current corona discharge generally uses a single positive corona or negative corona, lacking positive and negative corona, that is, lacking solid particles. The growth process; dielectric barrier discharge is more suitable for the treatment of volatile organic compounds, but it has almost no treatment effect on solid particles. At present, the dielectric barrier discharge used in indoor purifiers generally uses air as the discharge gas, and the air discharge method Ozone plays a major role in the treatment of pollutants. Ozone is a broad-spectrum fungicide, which has a good effect on removing volatile harmful gases and bacteria and microorganisms. However, when the concentration of ozone exceeds a certain standard, it will It will cause certain harm to the human body, so many plasma air technologies now use as little plasma generating devices as possible to generate ozone. The reduction of ozone production will definitely weaken the effect of air purification. In addition, this method is still It is difficult to ensure that the ozone content produced by the plasma air purifier exceeds the standard after working in a closed indoor environment for a long time
