Abstract

The invention relates to a treating system for governing waste gas of volatile organic compounds (VOCs) through plasma. The treating system comprises a heat exchanger, a combustion chamber, an induceddraft fan, a plasma spray gun, a waste gas connecting pipeline and a valve; a waste gas source is connected with the combustion chamber through the heat exchanger and is a place or equipment capableof generating the waste gas of the VOCs, and the heat exchanger can initially heat the waste gas of the VOCs; and the combustion chamber is connected with the induced draft fan through the heat exchanger, the heat exchanger can conduct heat exchanging on gas and water generated in the combustion chamber, and the induced draft fan can discharge the gas treated through the heat exchanger into atmosphere. The treating system can be used in the aspect of governing the waste gas, generated by various industries and equipment, of the VOCs, the treated waste gas can meet the requirements of the emission standard of emitted gas in China, through the treating system, the treating efficiency of the waste gas of the VOCs is significantly improved, the waste gas is discharged to reach the standard, environment pollution is reduced, and the application prospects are quite wide.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a treatment system, treatment method and application of plasma treatment of VOCs waste gas. Background technique [0002] In recent years, my country's printing, steel industry, painting and drying room and other industries have developed rapidly, and industrial development is accompanied by environmental pollution. During the development process, a large amount of volatile organic compounds (Volatile Organic Compound, hereinafter referred to as VOCs) are produced. With the development of industry and the improvement of people's living standards, VOCs emissions are increasing day by day, and have the characteristics of wide range and large emissions. VOCs exhaust gas has a huge impact on human health. When VOCs exhaust gas in the indoor environment reaches a certain concentration, people will have headaches, nausea, vomiting, fatigue, etc., and in severe cases, ...
