Ultraviolet photocatalytic deodorization equipment, also known as ultraviolet deodorization equipment, photoelectric ion exhaust gas purification equipment, photocatalytic oxidation exhaust gas purification equipment, etc. It is an environmentally friendly equipment that can quickly remove various odorous gases such as volatile organic compounds, inorganic substances, hydrogen sulfide, ammonia, thiols, benzene, etc. The deodorization effect is good, and the deodorization effect greatly exceeds the odor pollutant emission standards issued by China (GB14554-93).

Application scope of ultraviolet photocatalytic deodorization equipment

Spray painting waste gas treatment, ink waste gas treatment, plastic waste gas treatment, chemical waste gas treatment, pharmaceutical waste gas treatment, sewage tank odor treatment, feed waste gas treatment, food workshop waste gas treatment, electroplating factory waste gas treatment, electronic waste gas treatment, rubber waste gas treatment, tire factory waste gas treatment, furniture factory spray painting waste gas treatment

Deodorization and purification of various types of exhaust gases with pollution sources such as car spray painting exhaust gas treatment, plastic factory exhaust gas treatment, casting exhaust gas treatment, etc.

Working principle of UV photocatalytic deodorization equipment:

After the organic waste gas is input into the photocatalytic deodorization equipment through exhaust equipment, UV ultraviolet beams and ozone are used to synergistically decompose and oxidize the odorous gases, reducing them into low molecular weight compounds, water, and carbon dioxide, which are then discharged outdoors through exhaust pipes

Introduction to UV photocatalytic deodorization equipment technology

This product utilizes a high ozone UV beam to irradiate odorous gases and TiO2 photocatalysis, catalyzing the cracking of odorous gases such as nitrogen, trimethylamine, hydrogen sulfide, methylmercaptan, dimethyl disulfide, carbon disulfide, and styrene, sulfides H2S, VOCs, benzene, toluene, and xylene. The molecular chain structure of organic or inorganic high molecular weight odorous compounds is degraded and transformed into low molecular weight compounds such as CO2 and H2O under UV beam irradiation.

The catalytic activity of TiO2 photocatalysis greatly affects the rate of photocatalytic reactions, and the photocatalytic activity of TiO2 is mainly influenced by its crystal form and particle size. The catalytic activity of rutile TiO2 is high. As the particle size decreases, the probability of simple recombination between electrons and holes decreases, and the photocatalytic activity increases. In addition, porosity, average pore size, particle surface state, purity, and other factors also have an impact on its photocatalytic activity. In order to improve the efficiency of photocatalytic degradation, TiO2 photocatalysts have been evolved and modified, such as developing nano TiO2, preparing TiO2 composite semiconductors, metal ion doping, dye photosensitization, etc. Various advanced methods can also be used to prepare TiO2 catalysts to enhance the activity of photocatalysts.

Using ozone UV beam to decompose oxygen molecules in the air to produce free oxygen, also known as reactive oxygen species. Due to the imbalance of positive and negative electrons carried by free oxygen, aerobic molecules combine to produce ozone. UV+O2 → O -+O * (reactive oxygen species) O+O2 → O3 (ozone). It is well known that ozone has a strong oxidizing effect on organic matter and has an effect on odorous gases and other irritating odors.

By using UV beams to break down the molecular bonds of pathogenic bacteria in odorous gases, the nucleic acid (DNA) of the bacteria is destroyed, and then oxidized by ozone to achieve deodorization and kill the bacteria.

Advantages of UV photocatalytic deodorization equipment

Removing Odor

It can remove major pollutants such as volatile organic compounds (VOCs), inorganic substances, hydrogen sulfide, ammonia, thiols, as well as various odors, with a deodorization efficiency of over 90%. The deodorization effect greatly exceeds the odor pollutant emission standards issued in China in 1993 (GB14554-93) and 1996 (GB16297-1996).

Need to add any substance

Just need to set up corresponding exhaust ducts and exhaust power, so that the odor/industrial waste gas can be decomposed and purified through this equipment without adding any substances to participate in chemical reactions.
