Photo-oxygen plasma purifier integrates ions, electrons, excited tai-atoms, molecules and free radicals in plasma, which are very active reactive species. It makes it difficult or slow to react quickly under normal conditions. They further react with pollutant molecules and ions, so that pollutants can be degraded, especially in favor of the treatment of refractory pollutants.

At present, under the increasingly stringent requirements of environmental protection, our country has also strengthened the control system for odor, especially for wood factories and forging hydraulic equipment after heat treatment. The odor produced in production is unpleasant and unpleasant. It is directly discharged into the atmosphere outdoors, which seriously affects the air pollution. Now a new type of equipment is introduced, which can deal with a small amount of dust brought by odor, and better deal with odor. The cost is cheap. The lamp tube in the equipment generally does not appear in 100,000 hours. The service life is long. The replacement lamp tube only needs to be taken down directly and put on the new lamp tube. The operation is simple and the maintenance is convenient. It is a modern equipment. The equipment covers a small area, has compact interior and is very light. The outer shell of the equipment is plastic-sprayed carbon steel, which is not easy to aging and has good corrosion resistance.

In addition, due to the downward transition of some energetic excited particles in the discharge of active ions and free radical gases, ultraviolet light can be generated. When the energy of photons or electrons is larger than the band gap of semiconductors, electrons in semiconductors will be stimulated, so that electrons jump from valence band to conduction band, forming a pair of highly active electron holes, and further inducing a series of redox reactions.
