Vertical UV indoor air disinfection purifier

Abstract

The invention relates to a vertical UV indoor air disinfection purifier comprising a shell, wherein the inside of the shell is divided into a pressure-balancing chamber, a UV disinfection chamber and an adsorption filtration chamber in turn from bottom to top; the upper part of the pressure-balancing chamber is provided with a pressure-balancing pore plate, the inside of the UV disinfection chamber is provided with a UV lamp for disinfection, the inside of the adsorption filtration chamber is provided with an adsorption filtration layer, the upper top of the shell is provided with an air outlet, the side of the lower part of the shell is provided with an air inlet, and the air inlet is connected with the lower part of the pressure-balancing pore plate. The multi-stage adsorption filtration layer can comprise a coarse filtration layer, a fine filtration layer and an adsorption layer in turn from bottom to top and also can be the adsorption filtration layer which is consistent upwards and downwards, the coarse filtration layer can be a plurality of layers of filter screens which are overlapped together, the fine filtration layer can be a plurality of layers of filter cloths which are overlapped together, and the adsorption layer or the adsorption filtration layer can be made from activated carbon fiber cotton or can be an activated carbon shell particle or molecular sieve particle layer. The invention has simple structure and convenient use, and is mainly suitable for the sterilization and purification of the indoor air with lower pollution concentration.

Description

technical field [0001] The invention relates to an air pollution control device, in particular to a purification and humidity control device for eliminating suspended solids and organic gas pollution in indoor air and adjusting indoor air humidity. 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. The existence of these pollutants not only makes people feel bad, but also affects people's health. Therefore, with the improvement of people's living standards and the aggravation of air pollution, the problem of indoor air pollution has become more and more widely con...

Problems solved by technology

At present, the method of indoor air purification mainly adopts pure mechanical filtration, electrostatic, chemical (or physical) adsorption, negative ion and photocatalytic at home and abroad. Due to the limited effect of pure mechanical filtration 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.
