Photocatalytic exhaust gas treatment equipment

Mainly using a specially designed high-energy high ozone UV beam to irradiate waste gas, cracking industrial waste gases such as ammonia, trimethylamine, hydrogen sulfide, methylthio, methyl sulfide, butyl acetate, ethyl acetate, dimethyl disulfide, carbon disulfide, styrene, sulfide H2S, VOC, benzene, toluene, xylene molecular chain structures are degraded and transformed into low molecular weight compounds such as CO2 and H2O under high-energy UV beam irradiation. Using high-energy and high ozone UV ultraviolet beams to decompose oxygen molecules and water molecules in the air to produce free oxygen (reactive oxygen species) and OH radicals. Due to the imbalance between free oxygen and the positive and negative electrons carried, it needs to combine with oxygen molecules to produce ozone. UV+O2-O+O * (reactive oxygen species)+O2-O3 (ozone), it is well known that ozone has a strong oxidizing effect on organic matter and has an effect on industrial waste gas and other irritating odors.

In addition, by adding special catalysts: more than 27 corresponding inert catalysts are configured according to different exhaust gas components. The catalyst uses honeycomb shaped metal mesh as a carrier, which is in contact with a light source. The inert catalyst undergoes catalytic reaction below 338 nanometer light source, amplifying the light source effect by 10-30 times, allowing it to fully react with the exhaust gas, shortening the contact time between the exhaust gas and the light source, and thus improving the exhaust gas purification efficiency. Catalysts also have a purification effect on exhaust gases similar to plant photosynthesis. By irradiating with specific wavelengths of light, nano photocatalysts are activated to generate electron hole pairs, which interact with surrounding H2O molecules and O2 molecules to generate hydroxyl radicals OH. Through the hydroxyl free base layer, various harmful components in the air are locked in, and the structure of harmful molecules is decomposed to inhibit bacterial growth and virus activity, thereby achieving the goals of sterilization, air purification, deodorization, and pollution elimination. After the industrial waste gas is input into this purification equipment through exhaust equipment, the purification equipment uses high-energy UV ultraviolet beams and ozone to synergistically decompose and oxidize the industrial waste gas, degrading and converting it into low molecular weight compounds, water, and carbon dioxide, which are then discharged outdoors through pipelines. By using high-energy UV beams to break down the molecular bonds of bacteria in industrial waste gas, the bacterial nucleic acid (DNA) is destroyed, and then oxidized by ozone to achieve the purpose of purification and killing bacteria. From the perspective of air purification efficiency, we have chosen a high corona current device that combines C-band ultraviolet radiation and ozone. We use the principle of pulse corona adsorption technology to eliminate harmful gases. C-band ultraviolet radiation is mainly used to remove organic gases such as hydrogen sulfide, ammonia, benzene, toluene, dimethylbenzene, formaldehyde, ethyl acetate, ethane, acetone, urea, resin, etc., transforming organic matter into inorganic matter.

The UV photolysis purification device consists of equipment and components such as a primary filtration unit, C-band ultraviolet device, catalytic device, degradation collection, ozone generator, and filtration unit.
