| 摘 要： | 采取模拟烟气通过含有强氧化性的溶液（H2O2和KMnO4）在鼓泡反应装置中进行单一的实验，研究吸收剂的温度和浓度对脱硝效率的影响，得出其最优脱硝条件，选取3种氧化剂的最优值进行并联实验，并分析其脱硝机理得出并联条件下的最优脱硝试剂。结果表明，H2O2的最优脱硝条件为：温度为60 ℃，浓度为0.5%，其达到稳定时的脱硝效率为58%；KMnO4的最优脱硝条件为温度为40 ℃，浓度为0.2%，达到稳定时的脱硝效率为77%；并联条件下最优脱硝试剂为KMnO4和NaClO2，其脱硝效率为83%。

| Abstract: | Take simulated flue gas through the solution (H2O2, KMnO4) containing strong oxidizing conducting impact single experiment, study absorbent temperature and concentration on denitrification efficiency in bubbling reaction apparatus, obtain optimal denitrification conditions, and select the optimal value three-oxidants pairwise parallel experiment analysis denitrification mechanism of denitration reagents obtained under optimal parallel conditions. The experimental results show that:the optimal Denitrification Conditions of H2O2 are as follows, the temperature is 60℃, the concentration is 0.5%, and the denitrification efficiency is 58%;The optimal Denitrification temperature and concentration of KMnO4 were 40℃, 0.2%, and the denitrification efficiency was 77%;and the denitrification efficiency was as follows, KMnO4 and NaClO2, the denitrification efficiency was 83%. |
