Abstract

The invention relates to a one-stage plasma catalysis in-situ diffuse reflection infrared detection device. Using in situ infrared methods to understand the role of plasmas in catalytic reaction mechanisms provides a method for optimizing catalyst and plasma operating parameters. The invention provides a detailed description for the design of the infrared diffuse reflection pool for the plasma synergistic heterogeneous catalytic reaction. The working gas is introduced into the gas chamber and discharged at the catalytic bed. The discharge tube and the window support are fixed and sealed with PTFE screws. The end of the high-voltage electrode is connected to the insulating pad, inserted from the bottom of the discharge tube, and is flush with the upper surface of the catalytic bed. The detection signal passes through the window and is diffusely reflected on the surface of the sample to be tested, and then converged by the concave lens and sent to the detector. The invention can realize in-situ infrared online monitoring of a one-stage plasma catalytic reaction process, and provides an important characterization means for exploring the reaction mechanism, and meanwhile, the invention is easy to operate and has a wide application range.

Description

technical field [0001] The invention relates to the design of a "one-stage" plasma catalysis in-situ diffuse reflection infrared detection device, which mainly includes the related design of the reactor window and the one-stage plasma discharge reactor. Background technique [0002] From PM, VOCs and NO x The problem of air pollution is becoming more and more prominent, so it is imminent to develop efficient and convenient solutions. The use of electrostatic precipitating methods to treat coal-fired power plants, heating boilers and other major industrial PM pollution sources in my country has made staged progress. At the same time, catalytic combustion and microbial degradation methods have been used to purify trace VOCs in industrial waste gases. effectiveness, but for industrial NO x There is currently no effective governance plan for governance, and the research work is still in the process of exploration. The selective catalytic reduction of hydrocarbons is considered...
