Description

TECHNICAL FIELD

[0002] With the rapid development of industrialization and urbanization, waste gas emission problem is increasingly serious, waste gas contains not only a large amount of harmful substances, but also may carry viruses and bacteria, which has a serious impact on human health and ecological environment. As a new type of waste gas treatment technology, plasma technology has been widely concerned and applied in recent years. The plasma waste gas sterilization and deodorization device is based on the principle of plasma technology, which utilizes the active particles such as high-energy electrons, positive and negative ions, excited state particles and active free radicals in plasma to chemically react with harmful substances in waste gas, and converts them into harmless substances. Specifically, a large number of small ion groups are generated by using electric field effect, and the small ions collide with oxygen molecules in the air to form positive and negative oxygen ions. The positive oxygen ions have strong activity and can oxidize and decompose methyl mercaptan, ammonia, hydrogen sulfide and other pollution factors in a very short time, and destroy the chemical chain of organic volatile gases. After a series of reactions, carbon dioxide and water are finally generated. At the same time, the positive oxygen ions can also destroy the living environment of bacteria in the air, so that the bacteria and spores lose activity, achieving the effect of sterilization and deodorization, and the negative oxygen ions can adsorb suspended particles that are several tens of times heavier than themselves, remove suspended colloids in the air, and achieve the purpose of purifying air.
