Matrix type dielectric barrier discharge plasma odor processing device

Abstract

The invention relates to a matrix type dielectric barrier discharge plasma odor processing device which is characterized by comprising a housing, discharge dielectrics, a fixing device, electrodes, electrode outgoing lines, discharge zones and a pulse power supply, wherein the discharge dielectrics are arranged by the fixing device in a matrix type, the electrodes are arranged in the discharge dielectrics and are connected with the pulse power supply through the electrode outgoing lines, and the discharge zones are arranged between the neighboring discharge dielectrics. The odor processing device can be convenient for regulating according to the concentrations of pollutants and the processing air amount of waste gas with foreign smell to make the strength generated by plasma match with the strength of the waste gas to be processed, thereby achieving the optimal pollutant removing effect and running energy consumption. The air resistance and the additionally applied voltage of the plasma reaction system are greatly reduced, the gas flux is enlarged, and the removing efficiency of odorants is improved by above 30%. The device has the advantages of compact structure, good processing effect on the pollutants with the odor and high efficiency and wide generalization and application prospect, and can be widely applied to processing waste gas containing the odorants, such as styrene, hydrogen sulfide, carbon disulfide, organic amine and the like.

Description

technical field [0001] The invention relates to a device for treating odor gas, in particular to a matrix type dielectric barrier discharge plasma processing device for odor gas. Background technique [0002] Odor is a kind of public nuisance gaseous pollutants that cause unpleasant sensations caused by the odorous substances in the atmosphere, water, soil, solid waste and other substances that act on the perception of human olfactory organs through the air medium and are harmful to human health. There are many kinds of odorous substances. So far, there are more than 4,000 kinds of odorous substances that can be felt by human sense of smell, but they are generally divided into three categories: ① sulfur-containing compounds, such as hydrogen sulfide, mercaptans, dimethyl Sulfur, sulfides and sulfur-containing heterocyclic compounds, etc.; ② nitrogen-containing compounds, such as ammonia, amines, nitriles, nitro compounds and nitrogen-containing heterocyclic compounds, etc.; ...

AI Technical Summary

Problems solved by technology

[0006] At present, the methods of generating plasma by dielectric barrier discharge mainly include sleeve type and flat plate type. In order to achieve a better discharge effect, the net distance between the inner and outer sleeves is generally less than 10mm, so the air resistance is relatively large, which greatly affects the flow of gas, making this discharge method only applicable to small-volume waste gas treatment

However, the flat-plate dielectric barrier discharge method for generating plasma is difficult to apply due to the problem of the connection between the electrode and the dielectric layer and the problem of sharp discharge at the corners.
