UV photocatalytic oxidation equipment

The UV photocatalytic oxidation equipment adopts advanced technological concepts in China and has been developed through long-term experiments by technical personnel. It is an environmentally friendly purification product with independent intellectual property rights that can decompose toxic and harmful substances in industrial waste gas and achieve deodorization and purification effects. The decomposed industrial waste gas can be discharged harmlessly without producing secondary pollution, while achieving high efficiency in killing bacteria.

UV photocatalytic oxidation equipment uses high-intensity nano ultraviolet radiation to destroy and decompose large molecular chains into small molecular chains, and then uses ozone and hydroxyl radicals for oxidation and catalytic oxidation with catalysts to convert organic matter into water and carbon dioxide, in order to achieve the goal of removing organic matter.

Working principle of UV photocatalytic oxidation equipment

Most semiconductor photocatalysts are n-type semiconductor materials (currently widely used as TiO2) that have a special band structure distinct from metals or insulating substances, namely a bandgap between a valence band and a conduction band.

Due to the relationship between the light absorption threshold and bandgap of semiconductors with the formula K=1240/Kg (eV), the absorption wavelength threshold of commonly used wide bandgap semiconductors is mostly in the ultraviolet region. When light with photon energy higher than the absorption threshold of the semiconductor is irradiated, the valence band electrons of the semiconductor undergo interband transitions, that is, from the valence band to the conduction band, thereby generating photo generated electrons (e -) and holes (h+). At this point, the dissolved oxygen adsorbed on the surface of the nanoparticles captures electrons to form superoxide anions, while the holes oxidize the hydroxide ions and water adsorbed on the catalyst surface into hydroxide radicals. And superoxide anions and hydroxyl radicals have strong oxidizing properties, which can oxidize the vast majority of organic matter to products CO2 and H2O, and even decompose some inorganic substances.

Performance advantages of UV photocatalytic oxidation equipment

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

2. No need to add any substances: just set up corresponding exhaust pipes and exhaust power to allow odor/industrial waste gas to be deodorized, decomposed and purified through this equipment, without adding any substances to participate in chemical reactions.

3. Strong adaptability: GY series odorous gas (industrial waste gas) UV photolysis waste gas purification equipment can adapt to high concentration, atmospheric volume, and different industrial waste gas substances for deodorization and purification treatment. It can work continuously 24 hours a day and operate stably and reliably.

4. Low operating cost: GY series odorous gas (industrial waste gas) UV photolysis waste gas purification equipment has no mechanical action, no noise, no need for dedicated management and daily maintenance, only requires regular inspections. This equipment has low energy consumption and extremely low air resistance<50pa, which can save a lot of exhaust power energy consumption.

5. The equipment has a small footprint and light weight: suitable for special conditions such as compact layout and narrow space. The equipment occupies an area of less than 1 square meter and can handle an air volume of 10000m3/h.

6. Imported material manufacturing: High fire and corrosion resistance, stable equipment performance, made of stainless steel material, equipment service life of more than 15 years.

7. Explosion proof certified products: The equipment has explosion-proof characteristics and has passed the Ex explosion-proof qualification certification (certificate number: CNEx13.0792X) of China's Explosion proof Electrical Product Quality Supervision and Inspection Center. It can be widely used in industries with high explosion-proof requirements such as oil and gas fields, petrochemicals, and pharmaceuticals.
