Description

technical field [0001] The invention relates to an air purification device, in particular to an indoor air purification device. Background technique [0002] With the rapid development of modern industry and agriculture, the corresponding pollutants are also increasing. People's demand for life is increasing day by day, especially for the pollutants in the closed space where people and animals live, such as formaldehyde, benzene, ammonia, hydrogen sulfide, smoke and so on. [0003] At present, the methods used to remove these pollutions mainly contain the following: 1. Ozone method: This method utilizes the strong oxidative property of ozone to decompose the polluted gases in the air. Although the method has the effect of purifying the air to a certain extent, the excessive Ozone will cause secondary pollution. In addition, the method of using ultraviolet rays to generate ozone can easily cause ultraviolet rays to leak, thereby causing harm to humans or animals. 2. Low-te...

AI Technical Summary

Problems solved by technology

The low-temperature plasma method can completely decompose organic matter, and has the function of high-voltage electrostatic dust removal, but ozone still remains in the treated air

3. Activated carbon adsorption method: Activated carbon is an important adsorbent for removing polluted gases by physical methods. Pollutants play a role in transfer, and the polluted gas is not really oxidized and decomposed; and the filter element needs to be cleaned and replaced regularly, so this method cannot really remove the pollutants in the air

However, since the photocatalytic reaction is a surface reaction, whether the pollutants can fully contact the surface of the catalyst will directly affect the efficiency of the air purifier.

[0004] It can be seen that due to the limitations of the above-mentioned technology itself, the purpose of efficiently removing pollutants in the air cannot be achieved, and it may even cause secondary pollution
