Microwave plasma industrial organic waste gas treatment system

Abstract

The invention discloses a microwave plasma industrial organic waste gas treatment system and belongs to the technical field of organic waste gas treatment equipment in the chemical industry. The treatment system comprises a housing with the size matching with the size of an industrial organic waste gas pipe and multiple same microwave plasma torch generation devices fixedly and uniformly distributed around the housing along the circumferential direction. Each one of the microwave plasma torch generation devices comprises a microwave generator, a circulator, a water load and a microwave waveguide resonance cavity and the above parts are orderly connected. A non-metallic microwave discharge tube is arranged at a position with the maximal microwave electric field amplitude in the microwave waveguide resonance cavity. A discharge pipe is perpendicular to the axial direction of the microwave waveguide resonance cavity and the lower end of the discharge pipe extrudes from the microwave waveguide resonance cavity. A discharge metal wire is fixedly arranged in a discharge pipe cavity. The microwave generator is close to the center of the housing. The tail end of the microwave waveguide resonance cavity is fixedly connected to the housing. The system utilizes air plasma produced by microwave to treat industrial organic exhaust gas and has the characteristics of high overall efficiency,short process and cost saving.

Description

technical field [0001] The invention belongs to the technical field of organic waste gas treatment equipment in the chemical industry, and in particular relates to a microwave plasma industrial organic waste gas treatment system. Background technique [0002] With the continuous development of the scale of my country's chemical industry manufacturing enterprises, there are many black factories that produce and discharge waste in the production process of chemical enterprises, especially the industrial organic waste gas discharged by a large number of chemical enterprises is discharged into the air without treatment, directly polluting the atmosphere Quality, which has a serious impact on the global climate and local environment. [0003] The current treatment methods for waste gas in the chemical industry mainly include thermal combustion, catalytic combustion, absorption and adsorption, condensation recovery, biological treatment and corona discharge. And this kind of metho...
