Problems solved by technology

[0006] However, the contact frequency between the photocatalyst and polluted gas in the existing purification equipment is low, and the mass transfer efficiency of pollutants diffused to the surface of the photocatalyst is low, so that VOCs cannot be completely removed; at the same time, the light receiving surface of the photocatalyst is not enough.

Abstract

The invention relates to an air purification device. A rotating wheel type photocatalysis air purification device applied indoors comprises a shell (1), a rotating shaft (2), a motor (3), ultraviolet lamps (4) and clamps (7), wherein the ultraviolet lamps (4) and the clamps (7) are arranged on the surface of the rotating shaft at intervals, strip-shaped photocatalyst carriers are fixed through the clamps in a pressing fixing mode, the photocatalyst carriers are distributed in the radial direction of the shell, and the length of the photocatalyst carriers is smaller than the radius of the shell. The rotating wheel type photocatalysis air purification device can be applied to various occasions such as newly-decorated houses, office buildings and production workshops. The clamps and the ultraviolet lamps are arranged on the surface of the rotating shaft, the strip-shaped photocatalyst carriers are arranged, and therefore the utilization rate of the space inside the rotating wheel type photocatalysis air purification device is greatly increased, the contact area of polluted air and catalysts is enlarged, the contact frequency of polluted air and the catalysts is increased, the mass transfer efficiency between pollutants and the photocatalysts is effectively improved, the rotating wheel type photocatalysis air purification device is suitable for various occasions, and the utilization efficiency of the ultraviolet lamps is improved.

Description

technical field [0001] The invention relates to an air purification device, in particular to a wheel-type photocatalytic air purification device applied indoors. Background technique [0002] The continuous development of society makes people more and more enjoy the comfort and convenience brought by economy and technology, but at the same time pushes human beings to the embarrassing situation of resource depletion and environmental degradation. [0003] In today's society, "indoor air pollution" is considered to be the third largest type of pollution after "soot type" and "photochemical smog type" pollution. The "2002 World Health Report" published by the World Health Organization shows that nearly half of the world's people are exposed to indoor air pollution, which has caused 35.7% of respiratory diseases, 22% of chronic pneumonia, and 15% of tracheitis, bronchitis and Lung cancer is caused by indoor air pollution. Indoor environmental pollution has been listed as the to...
