Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a high-efficiency low-temperature plasma generator. Background technique [0002] In recent years, low-temperature plasma technology has attracted more and more attention. Plasma is called the fourth form of matter besides solid, liquid and gas, and is composed of electrons, ions, free radicals and neutral particles. Yes, the overall electrical neutrality is maintained. In the low-temperature plasma, there are a large number of high-energy electrons and active particles such as O and OH produced by high-energy electrons, and then a series of complex physical and chemical reactions are triggered to transform complex macromolecular pollutants into simple small molecular substances. Or change toxic and harmful substances into non-toxic, harmless or low-toxic and low-harm substances, so that pollutants can be degraded and removed. Low-temperature plasma technology has the ...
