Horizontal indoor air purifier mainly using ozone oxidation

Abstract

The invention relates to a horizontal indoor air purifier mainly using ozone oxidation. The horizontal indoor air purifier comprises a casing, wherein the cross section of the casing is rectangular, and the inside of the casing is divided into a pressure balancing chamber, an ozone oxidation chamber and an adsorption chamber successively. The product provided by the invention has the following beneficial effects: air enters the casing from an air inlet, particulate matters in the air are filtered and removed through multiple stages of filtration layers, and then the air flow continues to move backwards; and in the ozone oxidation chamber, volatile organic gas molecules in the air are oxidized by ozone generated by irradiation of an ozone ultraviolet lamp to form harmless or basically harmless inorganic matters, then the air flow enters an adsorption layer, the residual volatile gas molecules are adsorbed, and after the purification treatments, purified air flows out of an air outlet.

Description

technical field [0001] The invention relates to a horizontal indoor air purifier mainly based on ozone oxidation. Background technique [0002] People spend at least half of their life indoors. Due to the effective indoor space and less exchange with outdoor space, the indoor environment itself not only has no natural purification ability, but also due to the popularity of indoor decoration and air conditioners As well as people's daily life, pollutants are continuously discharged into the indoor space, mainly volatile organic compounds, solid suspended particles and aerosols, among which the main pollutants include formaldehyde and benzene series. The existence of these pollutants not only makes People have bad feelings, but also affect people's health, so with the improvement of people's living standards and the aggravation of air pollution, the problem of indoor air pollution has been more and more widely concerned by people. At present, the method of indoor air purifica...

AI Technical Summary

Problems solved by technology

At present, the method of indoor air purification mainly adopts pure mechanical adsorption, electrostatic, chemical (or physical) adsorption, negative ion and photocatalytic at home and abroad. Due to the limited effect of pure mechanical adsorption and electrostatic dust removal on air purification , mainly used to remove suspended particles, the degree of purification of organic pollution is not high, so it has been gradually eliminated

The products under several other technologies also have their own advantages and disadvantages, which are respectively adapted to different pollutant purification and different customer requirements. For example, the adsorption purifier can absorb specific or even most organic pollutants according to the characteristics of the selected adsorption materials. matter, but there is a problem of saturation of the adsorption material, which requires regeneration and replacement of the material. For occasions with a high concentration of particulate matter, the clogging of the particulate matter will affect the adsorption capacity of the adsorption material, and negative ions are conducive to the decomposition of organic matter, making it form Basically harmless carbon dioxide, water and other inorganic substances, and also has a certain air freshening effect, which helps to improve the quality and comfort of the air, but the products in the reaction process also have adverse effects on the human body to some extent , its ability to control bacteria, viruses and chemical pollutants is also very limited; in recent years, a rapidly developing technology is photocatalytic purification technology based on nano-photocatalysts. Under the irradiation of natural light, it decomposes organic pollutants and has a good bactericidal effect. However, as a unit operation process, it still has limitations, such as relatively low purification efficiency, and the ability to remove pollutants is limited in practical applications.
