Air purifier

Abstract

The invention discloses an air returning box type photocatalysis air purifier which comprises a shell, a draught fan, a filter and photocatalysis structures. Photocatalysis filter screens and ultraviolet sources are arranged in the photocatalysis structures, the photocatalysis filter screens are longitudinally arranged in the shell in parallel, and the ultraviolet sources are horizontally mounted in the shell. The purification process design is as follows: multiple photocatalysis structure assemblies are mounted in the shell, after the photocatalysis structure assemblies are placed on an air filtering work section of an air returning box, a central air-conditioning system sucks returned air with a large number of pollutants into the air returning box through a return fan, the returned air is mixed by a mixing section and cooled by a surface cooling section and then enters the shell to be subjected to photocatalysis air purification, after purification is completed, the air is processed and disposed through other work sections in an air-conditioner, and at last the air is blown out through a forced draught blower after being filtered; accordingly, circulation is conducted in this way, the air is continuously purified, and the quality requirement for indoor air is met. The air returning box type photocatalysis air purifier is characterized in that the photocatalysis structures are directly mounted in the air returning box of the central air-conditioning system, the space is saved, meanwhile, the self reaction efficiency is high, the ultraviolet sources are fully used, energy consumption is small, the air purifier can be combined with the other functions of the central air-conditioner, and the air is processed to be in the best state.

Description

technical field [0001] The invention relates to an air purifier, especially one that is combined with heating, gas supply, ventilation and air-conditioning systems, uses photocatalytic technology to effectively degrade volatile organic compounds VOCs produced by indoor air pollution in the return air box, and monitors air quality. An adjusted and improved purification device belongs to the field of air purification. Background technique [0002] In recent years, the increase in the pollution degree of the outdoor atmosphere has continuously aggravated the deterioration of the indoor air quality. At the same time, with the improvement of people's requirements for the comfort of indoor living environment, all kinds of new household items bring convenience to our life, but also bring us serious pollution in terms of indoor air quality—these household materials A large amount of poisonous and harmful gases released gather indoors, resulting in a serious decline in indoor air qu...

Problems solved by technology

Its products use photocatalytic technology to purify indoor air, but its own structure is complicated to install, and it does not take into account the above-mentioned improvement and optimization of the structural module space of the air purification itself, and it does not reflect that it is installed in combination with the air conditioning system. The advantages of improving air quality together with other air treatment functions of the system
