Microwave photocatalytic oxidation waste gas treatment equipment


working principle:
1. This product uses a special high-energy, high-ozone UV ultraviolet light beam to illuminate malodorous gases, and cracks malodorous gases such as ammonia, trimethylamine, hydroge sulfide, methyl sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide and benzene. The molecular chain structure of ethylene, sulfide H2S, VOC, benzene, toluene, xylene and other exhaust gases, so that the molecular chain of organic or inorganic high-molecular malodorous compounds is degraded into low molecular compounds such as CO2 under the irradiation of high-energy ultraviolet light beams. H2O and so on.
The high-energy UV beam is used to crack the molecular bonds of bacteria in the malodorous gas, destroy the nucleic acid (DNA) of the bacteria, and then carry out oxidation reaction through ozone to completely achieve the purpose of deodorizing and killing bacteria.
Second, the use of high-energy high-ozone UV ultraviolet light beam to decompose oxygen molecules in the air to produce free oxygen, that is, active oxygen, due to the imbalance of positive and negative electrons carried by free oxygen, it needs to be combined with oxygen molecules to produce ozone.
UV+O2→O-+O* (reactive oxygen) O+O2→O3 (ozone), it is well known that ozone has a strong oxidation effect on organic matter, and has an immediate effect on the removal of malodorous gases and other irritating odors.
Third, nano-photocatalytic TiO2, its mechanism of action is simple: nano-photocatalyst TiO2 is excited to generate "electron-hole" pair (a kind of high-energy particle) under the irradiation of light of a specific wavelength, this "electron-hole" pair After acting on the surrounding water and oxygen, it has a strong oxidation-reduction capacity, which can directly decompose pollutants such as aldehydes and hydrocarbons in the air into harmless and odorless substances, and destroy the cell walls of bacteria and kill them. Bacteria break down their mesh cells to achieve the goal of eliminating air pollution.
4. After the odorous gas is collected into the purification equipment by the collection and exhaust equipment, the purification equipment uses a combination of high-energy UV ultraviolet light beam, ozone O3 and nano photocatalytic TiO2 to synergistically decompose and decompose the exhaust gas to convert the exhaust gas into harmless. Odorless compounds, water and carbon dioxide are then discharged through the exhaust duct.
