Description

technical field

[0001] The invention relates to a waste gas purification device, in particular to a non-uniform field strength plasma waste gas treatment device and a treatment system. Background technique

[0002] With the development of the economy, the gaseous pollution produced in the field of industrial production, such as H 2 S, SO 2 , NO x 、VOC s problems are also becoming more and more serious. Relevant national laws and regulations and industry standards have strict restrictions on gas emission standards, and the control of polluted gases is the key to improving environmental quality.

[0003] The traditional methods of controlling polluted gases include combustion method, adsorption method, biological method, membrane separation method, photocatalytic method and so on. The disadvantage of the combustion method is that it consumes more auxiliary fuel, wastes heat energy, and causes secondary pollution during incomplete combustion; High consumption, complex pro...
