【摘要】 本文研究邻氨基酸磺酸盐的亚铁鳌合物清除ＮＯｘ的原理和方法，并用气相色谱法监测ＮＯ清除体系中不断变化的ＮＯ浓度，ＮＯ清除率可达８９％以上。经对不同人口浓度的ＮＯ进行实验，ＮＯ清除率均在８０％以上，从而可为不同来源的ＮＯｘ治理提供一种可供选择的方法。随着ＮＯ的吸收，Ｆｅ２＋被氧化，ＮＯ吸收率逐渐下降。采用酸性条件下加锌粉还原高铁为亚铁的方法，可使吸收液再生而循环使用，再生吸收液的ＮＯ清除率仍可保持在８０％左右。本研究不仅可降低ＮＯ治理成本，还可实现烟道气同时脱硫和脱硝。更多还原

【Abstract】 This paper deals with the use of ferrous complexes of orthalkamine sulfosaltfor the removal of NO in wet flue gas clean - up systems, and we use the gas chromatography to determine the comsistency of NO in the flue gas system. Orthogonal design is usedto optimize the experimental condition of the absorbing experiments, the absorbing effeciencyis 89 %. The effciencies of absorbing are all above 80% When we change the consistency ofthe inlet simulated gas, and it could provide a selective method for the absorption of NO.With the absorbing experiment going on, the ferrous ions could be oxidized into the ferricions, and it make the effeciencies of NO absorption is lowered. When the excess Zn powderis put into the solution and Fe2+ could be reduced back Fe3+. The experimental resultshowed that the effeciencies of the NO absorbing could still reach 80 % after the regenerationexperiment carried out, thus, it is possible that the recycle of the reagents. Thus, this process not only make the comprehensive utilization of the raw material, but also make it possible for the simultaneous removal of NO and SO2 in wet flue gas clean M up systems.更多还原
