Device for treating organic smelly waste gas by utilizing coupled dielectric barrier discharge plasma

Abstract

The invention relates to a device for treating organic smelly waste gas by utilizing coupled dielectric barrier discharge plasma and belongs to the technical field of organic smelly waste gas treatment process. The device comprises an upper air inlet distribution pipe, an upper air outlet collecting pipe, a lower air inlet distribution pipe, a lower air outlet collecting pipe, an upper discharging pipe air inlet, an upper discharging pipe air outlet, a lower discharging pipe air inlet, a lower discharging pipe air outlet, a bracket, a pedestal, a discharging pipe, a discharging pipe flushing system and a spraying system which is coupled in the upper air outlet collecting pipe and the lower air outlet collecting pipe. The coupled dielectric barrier discharge plasma has a compact structure, a good smelly pollution treatment effect and high energy efficiency, and can be widely applied to treatment on waste gas containing smelly substances such as benzene series, aldehyde, alcohol, carbon disulfide, organic amine and the like.

Description

technical field [0001] The invention belongs to the technical field of organic odor waste gas treatment technology, and is a process technology that combines two methods of dielectric barrier discharge plasma and spray washing method in one device to realize cooperative treatment of organic odor waste gas. Background technique [0002] Odor, as an environmental hazard, has become a hot spot of residents' complaints and concerns, and it has a wide range of sources, such as petrochemical, pharmaceutical, chemical fiber, leather and other industries. There are many kinds of odorous substances. So far, there are more than 4,000 kinds of odorous substances that can be sensed by people's sense of smell, and most of them are organic pollutants that are more harmful to the human body. In order to improve the quality of the living environment of residents and solve the problem of disturbing residents caused by odorous gases, the purification and treatment of organic odor pollution ha...

AI Technical Summary

Problems solved by technology

[0008] In view of the above two problems, the present invention provides a dielectric barrier discharge plasma combination device with wider adaptability and better purification effect, which eliminates the deposit problem affecting stable discharge through the discharge tube flushing system, and eliminates the problem of deposits affecting stable discharge through the discharge tube flushing system, and through the The spray system performs deep purification of exhaust gas to eliminate secondary pollution problems. At the same time, through instant spray washing, it also avoids the deposition of aerosol-like substances in the air outlet collection pipe, eliminates potential safety hazards, and realizes the large-scale industrialization of DBD plasma application
