[0002] Volatile organic compounds are usually represented by VOCs, and total volatile organic compounds are sometimes represented by TVOC. VOCs participate in the formation of ozone and secondary aerosols in the atmospheric environment, and have an important impact on regional atmospheric ozone pollution and PM2.5 pollution. Most VOCs have a special unpleasant odor and are toxic, irritating, teratogenic and carcinogenic. Benzene, toluene and formaldehyde in particular can cause great harm to human health. VOCs are important precursors to urban haze and photochemical smog, and are mainly derived from coal chemical industry, petrochemical industry, fuel coating manufacturing, solvent manufacturing and use, and other processes.

[0003] According to the description of a disclosed air volatile organic pollutant purification device (authorization announcement number: CN207324514U), "an air volatile organic pollutant purification device includes a dust collector, a catalytic reactor and an exhaust gas absorption device; after the air volatile organic pollutants are purified by the dust collector, the synergistic effect of plasma and catalyst in the catalytic reactor greatly improves the efficiency of removing air volatile organic pollutants, while avoiding the secondary pollution gas generated by photocatalyst technology, and the equipment is simple and easy to clean and maintain."
