Embodiment Construction

[0028] Examples Select toluene, a representative organic pollutant, as the treatment object to illustrate the implementation and treatment effect of the sleeve-type DBD plasma-coupled discharge tube flushing system and the outlet air collection pipe spray system.

[0029] Under the action of induced draft fan, the concentration is 850mg / m 3 The toluene-containing organic odor gas enters the coupled dielectric barrier discharge plasma reaction device. The gas treated by the plasma reactor is dewatered by the water eliminator and then discharged from the chimney. It is sampled and analyzed at 1m from the outlet of the induced draft fan. The accuracy of each sampling is fixed, and the sampling starts after the reactor runs stably for 30 minutes.

[0030] Coupled DBD plasma reactor: 1 set, processing capacity 3000m 3 / h.

[0031] The number of discharge tubes assembled is 96 pieces.

[0032] Use 1% lye as discharge tube flushing solution.

[0033] The sprinkler system uses H ...

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...
