The high-energy and high ozone ultraviolet beam is used to decompose oxygen molecules in the air to produce free oxygen, namely active oxygen. Because the positive and negative electrons carried by free oxygen are unbalanced, it needs to combine with oxygen molecules to produce ozone. UV+O2 → O -+O * (active oxygen) O+O2 → O3 (ozone). As we all know, ozone has a strong oxidizing effect on organic matter, and has an immediate effect on the removal of organic gases and other irritating odors. After the organic gas is input into the purification equipment through the exhaust equipment, the organic (odor) gas is decomposed and oxidized by high-energy ultraviolet beam and ozone, so that the organic gas substances can be degraded into low molecular compounds, water and carbon dioxide, and then discharged out of the room through the exhaust pipe.
