摘要
在鼓泡反应装置中进行了MgO为吸收区吸收剂、NaClO2为氧化区吸收剂的脱硫脱硝实验,研究了NaClO2浓度、NaClO2溶液的pH、温度和烟气体积流量等参数对脱硫脱硝效率的影响,并在液相产物分析的基础上推测了反应历程。结果表明:在最佳条件下,SO2和NO的脱除效率均达到100%,NOx的脱除效率可达65%。
Based on separated layout of different absorbents,an experimental study was carried out in two bubbling reactors on the simultaneous desulfurization and denitrification with MgO and NaClO2 as the absorbents respectively for the absorption region and oxidizing region,so as to analyze the effects of following factors on the desulfurization and denitrification efficiency,such as the concentration and initial pH value of NaClO2 solution,the reaction temperature and the flue gas flow rate,etc.In addition,the reaction mechanism was deduced based on an analysis of the liquid products.Results show that the removal efficiency of both SO2 and NO could reach 100%,under optimal experimental conditions,while the removal rate of NOx could achieve 65%.
