Photooxygen catalytic deodorization equipment The general process is that after the odor gas is input into the purification equipment by the exhaust equipment, the purification equipment uses high-energy UV beam and ozone to carry out cooperative decomposition and oxidation reaction on the odor gas, so that the odor gas substances can be degraded into low molecular compounds, water and carbon dioxide, and then discharged out of the room through the exhaust pipe. At the same time, the high-energy UV beam is used to split the molecular bonds of bacteria in the odor gas, destroy the nucleic acid (DNA) of bacteria, and then carry out the oxidation reaction through ozone to completely achieve the purpose of deodorization and sterilization.
