Problems solved by technology
At present, the air purifiers on the market mostly use methods such as filtration, electrostatic adsorption, and ultraviolet irradiation because of their single function and weak passive sterilization effect. Irritation; although hydrogen peroxide is an ideal bactericidal disinfectant, it is not operable in a dynamic environment; as for photocatalyst, it can only be an antibacterial agent rather than a disinfectant, and it is even less likely to be used in air disinfection

The invention discloses a micro-plasma air purifying method. According to the method, air is introduced into a micro-plasma device comprising a micro-plasma reactor and a high-voltage power supply; the high-voltage power supply is started and the micro-plasma reactor starts working; air between electrodes is broken down and ionized through the applied high voltage to generate micro-arc micro-plasma; air in a plasma area is subjected to plasma-chemical reaction under the effects of high-energy electrons, free-radical active materials and an electric field and the DNA of bacteria and viruses can be directly destroyed, so that the bacteria and viruses can be effectively extinguished, and the purified air is exhausted through an air outlet. The micro-plasma air purifying method is free of medicals, can be quickly performed or stopped, is nearly applied to air purification in various indoor environments, and is particularly applicable to bacteria removal and killing of viruses spreading through the air.
Description
technical field [0001] The invention relates to air purification technology, in particular to a micro plasma air purification method. Background technique [0002] In my country, in recent years, with the frequent attacks of various infectious diseases and smog, people are paying more and more attention to indoor air quality. From the government, hospitals, enterprises to consumers, they have begun to pay great attention to air quality. Buying air purifiers Devices have become one of the methods for people to prevent the spread of viruses. There is no doubt that the market prospect of air purifiers in China is promising. At present, the air purifiers on the market mostly use methods such as filtration, electrostatic adsorption, and ultraviolet irradiation because of their single function and weak passive sterilization effect. Irritation; although hydrogen peroxide is an ideal bactericidal disinfectant, it is not operable in a dynamic environment; as for photocatalyst, it ca...
