Chemical Kinetics And Experiment Study Of Removing Pollutants From The Gas Stream By Dielectric Barrier Discharge

The low temperature plasma technology, dielectric barrier discharge reactor has a good application prospect in the field of gaseous pollutants removal reduction. But the dielectric barrier discharge reactor is not widely used in China, because its high energy consumption, gas flow quantity and high cost. This paper mainly states the treatment of gas by self-made cylindrical dielectric barrier discharge reactor, the gas contains O2, N2, NO and Ar. This paper mainly studies the NO removing rate and the energy consumption under different conditions. Optimization dielectric barrier discharge reactor from four aspects:the length of the reactor, gas flow amount and gas gap. Anglicizing the NO removing rate and energy consumption under different gas components. Useing Plasma Plug Flow Reactor model simulates different gas.The results showed that the NO removing rate increases as dielectric barrier discharge reactor's length increases, the longer dielectric barrier discharge reactor not only takes too much spaces but also increase NO removing rate indistinctively, because the dielectric barrier discharge reactor's length has tremendous influence to the production of O; The flow rate affects NO removing rate mainly through the creation of N; After add Ar, the energy consumption is reduced. Because the adding Ar makes is easier to electric discharge and reduce the energy for discharge; The adding oxygen increase the quantity of O, but NO dose not dramatic decline.This research will prepare for the further mechanism analysis, for further studies to reduces the space which the dielectric barrier discharge reactor occupies and reduce the energy consumption, increases the gas quantity, enable this technology will be able to apply in the actual production.
