The plasma generates particles with high chemical activity, such as electrons, ions, free radicals and excited molecules. The pollutants in the waste gas react with these active genes with high energy, and finally convert into C02, H20 and other substances, so as to achieve the goal of purifying the waste gas. Wide application range, high purification efficiency, especially applicable to multi-component odor and organic waste gas that are difficult to be treated by other methods. The equipment occupies a small area; Electronic energy is high, and it can interact with almost all odor and organic waste gas molecules; Low operation cost; Quick reaction, very fast stop, with Sui Kai. But the one-time investment cost is high.
