Vertical indoor air purifier capable of effectively removing volatile organic gas

Abstract

The invention relates to a vertical indoor air purifier capable of effectively removing volatile organic gas. The vertical indoor air purifier comprises a shell. The interior of the shell is sequentially divided into an ozone oxidation chamber, a photo-catalytic reaction chamber and an adsorption chamber from bottom to top. The ozone oxidation chamber is internally provided with ozone ultraviolet lamps. A filter layer is arranged below the ozone ultraviolet lamps. A photo-catalytic ultraviolet lamp is arranged in the photo-catalytic reaction chamber. Photocatalyst filter screens are arranged above and below the photo-catalytic ultraviolet lamp. An adsorption layer is arranged in the adsorption chamber. An air outlet is formed in the top of the shell, and an air inlet is formed in the side face of the lower portion of the shell. The air inlet is connected to the space, below the filter layer, in the shell. The photocatalyst filter screens are coated with a nano titanium dioxide photocatalyst. Blocky active carton fiber cotton is preferably selected as an adsorption material. The vertical indoor air purifier is simple in structure and convenient to use, has a quite high purification rate to the volatile organic gas, and is mainly suitable for indoor air pollution control.

Description

technical field [0001] The invention relates to a vertical indoor air cleaner capable of efficiently removing volatile organic gases. 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...

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.
