| 摘 要： | 采用臭氧定量氧化NO，并结合湿法吸收进行脱硫脱硝实验研究。吸收实验选取3种常见碱性吸收液，采用鼓泡法进行NOx脱除效果对比，最终选定0.05 mol·L-1的Ca（OH）2乳浊液为吸收液。考察了NO和NO2不同配比下的吸收效果，当氧化度为60%（NO2/NO物质的量比1.3）时，吸收效果最佳。臭氧氧化实验结果表明，O3/NO物质的量比为0.6时能达到最佳氧化度，碱液吸收NOx脱除效率能达到76%，SO2脱除效率达100%。当改进鼓泡方式后，最佳氧化度条件下NOx脱除效率提高到85%。碱液pH对该法脱硝效率有影响，SO2的存在对NOx的脱除有一定促进作用。

| Abstract: | NO was quantitatively oxidized by ozone. NOx and SO2 were simultaneous absorbed with solution. Absorption test chose 3 common alkaline liquor to screen removal efficiency of NOx with bubbling. Finally 0.05 mol·L-1 Ca(OH)2 emulsion was chosen to use. Analysis of absorption performance by finding best ratio of NO2 to NO showed the best oxidizability is 60%. Oxidation experiment comes to the best oxidizability when ratio of O3 to NO is 0.6. And removal efficiency of NO reached 76%, SO2 reached 100%. Removal efficiency of NOx raised to 85% with the best oxidizability when bubble more fine. pH has an impact on removal efficiency and SO2 plays a role in helping NOx absorption. |
