Abstract

The invention discloses an air purifying method and device. The method comprises the following steps of: feeding a gas into an ultraviolet-ozone treatment region; reacting with ozone under the actions of ultraviolet irradiation and a photocatalyst; composing organic components in an oxidized gas; feeding the gas into a liquid absorbing device; further transforming difficultly-treatable organic components into treated substances and a harmless gas; and making the gas pass through a solid absorbing and drying device and exhausting the gas which reaches a purification standard. The device comprises a gas adjusting valve, an ultraviolet-ozone reaction device, a liquid absorbing device and a solid absorbing and drying device. According to the invention, the aim of purifying an environment is fulfilled by undergoing a photooxidation reaction under the action of the photocatalyst, air purifying efficiency can be increased, purification cost is reduced, safety is enhanced, damage of direct irradiation of ultraviolet rays to human bodies is avoided, and the defects of the prior art are overcome.

Description

technical field [0001] The invention relates to an air purification method and a device thereof, belonging to the fields of chemical engineering and environmental protection. Background technique [0002] With the development of industry and the improvement of life, people gradually realize the importance of environmental protection. How to deal with waste pollution is an urgent problem in the field of environmental protection. A large amount of volatile organic compounds and acid gases will be produced in production and life, especially benzene, toluene, xylene, sulfide and nitrate, which have become environmental pollutants that seriously affect human health. In modern life, it is inevitable that people will Exposure to harmful gases, such as newly bought cars, newly renovated rooms, newly bought furniture, etc., will release harmful gases. The media has repeatedly reported that the indoor formaldehyde concentration after decoration is too high, and mild cases can cause as...
