UV Photocatalytic Oxidation Deodorizing Equipment Remove Odor Light Oxygen Catalytic Exhaust Gas Purifier
UV photocatalytic equipment is an efficient waste gas treatment device, which is widely used in the field of industrial waste gas treatment through the combination of UV photolysis technology and catalytic oxidation technology to decompose the harmful substances in the waste gas. It is especially suitable for removing odour, volatile organic compounds (VOCs) and some toxic and harmful gases, such as benzene, toluene, xylene, hydrogen sulphide, ammonia and so on.
1. Working principle
The working principle of UV photocatalytic equipment mainly includes the following stages:
(1) UV photolysis
The high-energy ultraviolet lamps inside the equipment emit ultraviolet light with wavelengths of 185nm and 254nm, which directly destroys the chemical bonds in the molecules of the exhaust gas and breaks down the large-molecule pollutants into small-molecule compounds. For example, the benzene ring is decomposed into CO₂ and H₂O.
(2) Ozone oxidation
UV light can also break down oxygen molecules (O₂) in the air to form highly reactive ozone (O₃). Ozone is a strong oxidising agent that can further oxidise harmful substances in exhaust gases and convert them into non-toxic and harmless substances.
(3) Catalytic oxidation
The interior of the equipment is usually equipped with a catalyst coating or filler (e.g., titanium dioxide TiO₂), which, through the excitation of ultraviolet rays, forms highly active free radicals, further accelerating the degradation of hazardous substances in the exhaust gas.
(4) Discharge to standard
After the above treatment, the exhaust gas is converted into harmless substances such as carbon dioxide and water, and meets the environmental emission standards.
2. Applicable working conditions
A wide range of air volumes (from a few thousand cubic metres per hour to hundreds of thousands of cubic metres per hour).
Exhaust gases with complex composition, odours or VOCs (but with moderate concentration).
Exhaust gases that do not contain a lot of particles or are highly humid, and require front-end dust removal or dehumidification equipment.
