Chemical Reaction Kinetics Simulation Of Desulfuration And Denitration Via Dielectric Barrier Discharge

In recent years,considering the higher efficiency and the less energy wasted, Dielectric Barrier Discharge(DBD) plasma is regarded as the new and promising technology to resolve the problem recently.The micro mechanism of DBD influences the efficiency of DeSO₂/NO directly;the paper analysis chemical reaction kinetics of it, and a simplified model was built to describe the desulfuration and denitration process by DBD plasma.The software of Matlab as to be an auxiliary tool has been used to numerical calculated on computer.In a single pulse in DBD,the evolution of the main radicals and reactive species in different gas system as functions of time,volume concentration of component was analyzed in this paper;then,in the system of NO/SO₂/N₂/H₂O/O₂,the effect of the concentration of O₂ and H₂O,pulse energy and impulse frequency for DeSO₂/NO was studied;Last,simulation of the typical flue gas composition,Considering important effect of O,OH radicals on the DeSO₂/NO efficiency,the article researched of them primarily,the calculated results were in good agreement with related literature,verified the model is reasonable,could provide theoretic references of with practical application.
