Problems solved by technology

[0006] At present, the means of purifying the air is to use 185nm single-wavelength ultraviolet rays, but the purification efficiency of 185nm single-wavelength ultraviolet rays is low, and the use of 185nm single-wavelength ultraviolet rays alone will release ozone, which is strongly irritating and harmful to human health. Harmful, it can stimulate and damage the human respiratory tract, and can also damage the central nervous system, and has a mild stimulating effect on the eyes

Abstract

The invention provides a device and a method for decomposing air pollutants by dual-wave-length ultraviolet rays. The device comprises a box body and a box cover arranged on the box body. The device is characterized in that two sides of the box body are respectively provided with an air inlet and an air outlet, and the box body is internally provided with a baffle which separates the interior of the box body to be a first reaction area and a second reaction area, and the baffle is provided with a channel hole through which air passes; the first reaction area and the second reaction area are internally provided with ultraviolet lamps. The method for decomposing the air pollutants in the air comprises the following treatment steps: (1) irradiating polluted air by the ultraviolet lamp with the double wave lengths of 185nm and 254nm; and (2) irradiating the air treated from the step (1) by the ultraviolet lamp with the wavelength of 254nm. The air purified by adopting the method does not contain ozone, and prevents the secondary pollution.

Description

technical field [0001] The invention relates to an air purification device and method, in particular to a device and method for decomposing air pollutants by dual-wavelength ultraviolet rays. Background technique [0002] Environmental issues have always been the focus of attention of all countries in the world. As the largest developing country in the world, China's environmental pollution issues cannot be underestimated. [0003] China's resource consumption is mainly based on coal. With the increase of coal consumption, the total amount of sulfur dioxide emissions has risen sharply, and the scope of acid rain pollution caused by sulfur dioxide emissions has also continued to expand, directly causing my country's grain, vegetable and fruit production to decrease, and forests to die. Acidification of soil and water bodies. In addition, the harm caused by environmental pollution is also manifested in: 1) sulfur dioxide in the air even causes human respiratory diseases and in...
