Microwave plasma exhaust gas purification method

Abstract

The invention relates to a microwave plasma exhaust gas purification method. According to the microwave plasma exhaust gas purification method, a microwave plasma generator is used as a plasma gas source for generating high-energy active substances; a reaction chamber communicates with the gas outlet of the microwave plasma generator; air is introduced into the microwave plasma generator, and after a continuous and stable plasma gas flow occurs at the gas outlet, exhaust gas to be purified is introduced into the reaction chamber; and the plasma gas flow and the exhaust gas are mixed in the reaction chamber, the high-energy active substances contained in the plasma gas flow realize oxygenolysis of organic matters included in the exhaust gas, and then the exhaust gas is discharged. Through the split design of the exhaust gas and the plasma gas flow, volatile organic oxides and impurities such as dust in the exhaust gas are effectively prevented from contaminating the functional components of the microwave plasma generator; and thus, the service life of the microwave plasma generator is prolonged, and the purification effect of the microwave plasma generator is ensured. At the same time, since the exhaust gas does not enter and pass through the microwave plasma generator, plasma purification can be directly performed without pre-treatment.
