摘要
本文提出了基于Fenton试剂连续滴加的原位Fenton法(in situ Fenton,IF)用于氧化脱除烟气中NO的思路,并检验了其在氧化脱硝效果方面的优势。在此基础上,验证了将含有Fe^2+M^n+(M^n+=Fe^3+,Cu^2+,Co^2+,Mn^2+)的溶液作为诱导剂加入后的氧化脱硝效果。结果表明,原位Fenton法较常规Fenton法(premixed Fenton,PF)对NO的氧化效率高;除Fe^2+Fe^3+双离子溶液外,其他三种双离子溶液的加入对NO的氧化效率较单一离子参与的IF法都有明显的提升.此外,讨论了双离子间的适宜配比并推断出可能的氧化脱硝反应机理。
The in-situ Fenton system was put forward in this work for the first time,the advantages of it for the oxidation removal of NO from flue gas also has been verified.Besides,the experiments on the oxidation efficiency of NO through the in-situ Fenton system with Fe^2+Mn^+(Mn^+=Fe^3+,Cu^2+,Co^2+,Mn^2+)as reagents have been conducted.The results demonstrated that the oxidation efficiency of NO by the in-situ Fenton system was higher than the efficiency in the conventional premixed Fenton system.Except for Fe^2+Fe^3+ dual ions reagent,the oxidation efficiencies of NO through the other dual ionic in situ Fenton system were improved obviously when compared with the efficiencies by the single ionic in situ Fenton systems.Furthermore,the optimal molar ratio of Fe2^+:Mn^+ and possible mechanism of oxidation denitration were investigated and proposed.
