uvPhotolysisWaste GasEquipment Processing Overview
UV photodecomposition waste gas treatment equipment is a very common device in waste gas treatment. UV stands for ultraviolet light, and in our daily conversations, we often refer to "UV" as a shorthand for UV photodecomposition equipment. However, there is a misconception here. In UV equipment, there is also a device called a UV photodecomposition device. Both can be used to treat pollutants, but they have significant differences. Simply put, UV photodecomposition is a more advanced and efficient treatment device, and the photocatalytic reaction within it requires the illumination of a semiconductor (with titanium dioxide, TiO2 being the most widely used semiconductor) by ultraviolet light. Waste gas passes through the TiO2 grid, and pollutants are oxidized and decomposed.
uvPhotolysisTechnical Features of Waste Gas Treatment Equipment:
1. Free of any toxic side effects. Significantly surpasses traditional treatment devices, capable of continuous sterilization in occupied environments without posing harm to humans. It can broadly capture and eliminate various types of bacteria in the air, with tests showing a kill rate of over 95% for Bacillus subtilis, black variant spores, and natural bacteria. It effectively removes inhalable particles, achieving a cleanliness level of 1 to 100,000.
2. It effectively eliminates harmful and malodorous gases. Primary electrons are accelerated in the electric field, colliding with oxygen molecules in the air. When the energy exceeds the ionization potential of oxygen molecules, they rapidly ionize. Oxygen molecules that lose electrons become positively charged oxygen ions (O2+), while the released electrons combine with another neutral oxygen molecule to form negatively charged oxygen ions (O2-). The result is the polarization of oxygen ions and the adsorption of neutral oxygen molecules to form ion clusters such as O2+, O2-, and O2, which have oxidizing properties. They can oxidize and decompose harmful components in polluted air into harmless products and water in a very short time.
uvPhotolysisPerformance Advantages of Waste Gas Treatment Equipment:
1. Eliminate Odors: Capable of removing volatile organic compounds (VOCs), inorganic substances, and various malodorous gases, the deodorization efficiency can reach over 98%, significantly exceeding the 1993臭气污染物排放标准 (GB14554-93) and the 1996 Comprehensive Emission Standard for Air Pollutants (GB16297-1996) issued by the state.
2. No additional substances required: Simply set up the corresponding exhaust ducts and fans to facilitate the odor removal and purification of industrial waste gases through this equipment, without the need for any substances to participate in chemical reactions.
3. Versatile: UV photo-decomposition exhaust treatment can accommodate low, medium, and high concentrations as well as varying air volumes, and is suitable for deodorization and purification of industrial waste gases. It can operate continuously for 24 hours a day.
4. Low Operating Costs: The photochemical catalytic exhaust treatment equipment has no mechanical movements, produces no noise, and requires no dedicated personnel for management or daily maintenance. It only needs regular inspections. This equipment has low energy consumption and low air resistance ≤400Pa, which can save a significant amount of exhaust air power consumption.
5. The UV gas treatment equipment has a small footprint and light weight, making it suitable for installation under special conditions with compact layout and limited space.
6. Material Manufacturing: High fire and corrosion resistance, with safe and stable equipment performance, made of stainless steel, the equipment's lifespan exceeds 15 years.
7. Utilizing cutting-edge international technology concepts, the system can decompose toxic and harmful substances in industrial waste gases, achieving deodorization and purification. After decomposition, the industrial waste gases can be completely rendered harmless for emission, without causing secondary pollution, while also providing sterilization and bactericidal effects.
8. The UV photodecomposition waste gas treatment equipment features safety and explosion-proof capabilities, has passed the explosion-proof qualification certification from the National Supervision and Inspection Center for Quality of Explosion-Proof Electrical Appliances, and can be widely used in industries with high explosion-proof requirements such as oil (gas) fields and petrochemicals.
