【摘要】 应用介质阻挡放电方法在高温、不用催化剂的条件下,将模拟烟气中的SO2直接氧化成雾状H2SO4微粒,再采用静电收雾器回收,实现了资源化烟气脱硫.并就SO2原始浓度、H2O浓度以及等离子体反应时间等因素对SO2脱除率的影响进行了实验研究,结果表明,在SO2体积分数为400×10-6,O2浓度为21.0%,H2O浓度为4.0%条件下,SO2脱除率最高,达到了84.0%.更多还原

【Abstract】 The removal of SO2 from simulate flue is experimentally investigated using a dielectric barrier discharge and SO2 is directly oxidized into liquid drop H2SO4 under the conditions of high temperature and noncatalyst. In addition, some parameters which influence the removal efficiency of SO2 such as original concentration of SO2, concentration of H2O and plasma reaction time are studied in this experiment. The result shows that the removal efficiency of SO2 attains to 84.0% when concentration of SO2 is 400 ppm, concentration of O2 is 21.0%, concentration of H2O is 4.0%.更多还原
