At present, the biological deodorization method is the most common process for treating odor and has the advantages of low investment cost, low operation cost and the like. However, the biological deodorization method also has the defects of unstable treatment effect, large floor area, difficult start-up and the like. The chemical agent or the adsorbent is used for treating the odor, and is not economical and has common effect. Improper handling directly affects environmental safety and public health.
Therefore, an ultraviolet catalytic oxidation odor treatment device with low preparation cost, good chemical stability, good abrasion resistance and high treatment efficiency is needed. In order to solve the above problems, it is important to design a deodorizing device for efficiently catalyzing and oxidizing odor.

The wind-guard plates (7) in the device box body (9) are alternately arranged up and down, and a space is reserved between the front wind-guard plate and the rear wind-guard plate (7) to form an odor channel.
An LED ultraviolet lamp strip is arranged in the middle of the odor channel of the device.
The working process of the ultraviolet light catalytic oxidation odor treatment device is as follows:
1. cover odor collection cover (2) is added to odor source (1) top, and cover (2) are collected with the odor to tuber pipe a (3) one end, and the other end links to each other with air exhaust fan (4), and air exhaust fan (4) air outlet links to each other with tuber pipe b (5), and the other end and the ultraviolet photocatalytic oxidation odor treatment device of tuber pipe b (5) link to each other.
2. When the device operates, the ultraviolet light catalytic oxidation odor treatment device is started firstly, the air exhaust fan (4) starts to start after stable ultraviolet light is generated, and odor of the odor source (1) is sent into the ultraviolet light catalytic oxidation odor treatment device through the air exhaust fan (4), the air pipe a (3) and the air pipe b (5). After the odor enters the odor channel, organic matters in the odor begin to be continuously decomposed under the irradiation of ultraviolet light; meanwhile, when the ultraviolet rays pass through the air, oxygen in the air is ionized to generate ozone, the sterilization effect is enhanced, and organic pollutants are decomposed into carbon dioxide and water under the oxidation effect of the ozone, so that the defects of physical adsorption saturation and secondary pollution are overcome; the ultraviolet light irradiates titanium dioxide (TiO2) to generate electron holes or hydroxyl free radicals OH, organic protein is damaged, organic matters in odor are oxidized into carbon or CO2 and other harmless substances under the strong oxidation condition, and finally, the clean gas is discharged up to the standard.
