摘要
本次实验研究了强电离介质阻挡放电方法脱除烟气中的SO2,将其直接氧化成雾状H2SO4微粒,认为强电离介质阻挡放电脱硫方法是一种很有前景的方法.并就等离子体反应时间、SO2原始浓度、O2浓度以及H2O浓度对SO2脱除率的影响进行了实验研究,其结果显示,在SO2浓度为4.00×10-4(v/v),O2浓度为21.0%(v/v),H2O浓度为4.0%(v/v)条件下,SO2脱除率最高达到了84%.
The removal of SO_2 from flue is experimentally investigated by the strong ionization discharge of barrier discharge. SO_2 is directly ionized into liquid drop of H_2SO_4. In addition, some parameters such as plasma reaction time, original concentration of SO_2, concentration of O_2, concentration of O_2 and H_2O are studied in this experiment, which influence the removal efficiency of SO_2. The result shows that the removal efficiency of SO_2 attains to 84% when concentration of SO_2 is 4.00×10~-4(v/v), concentration of O_2 is 21.0%(v/v),concentration of H_2O is 21.0%(v/v).
