| 摘 要： | 采用自行开发的介质阻挡结合电晕放电装置进行模拟烟气脱除NO的实验研究,考察了丙酮对不同组成的烟气体系中脱除NO的影响,同时探讨了烟气脱除NO过程中丙酮添加剂的作用机理。结果表明:在NO/O_2/N_2体系中,增加O_2含量会降低NO的脱除率,极少量丙酮的加入可完全抵消O_2的抑制影响并能大幅提高NO的脱除率;在NO/O_2/N_2/CO_2体系中,CO_2的增加可降低NO的脱除率,极少量丙酮的加入可以明显减弱CO_2对NO脱除的抑制;在NO/O_2/N_2/CO_2/H_2O体系中,H_2O的加入可降低NO的脱除率,极少量丙酮的加入可以明显减弱H_2O对NO脱除的抑制。

Effects of Acetone on NO Removal by Dielectric Barrier and Corona Discharge |
| |
| Abstract: | The experiment of NO removal was conducted in a self-designed dielectric barrier and corona discharge device. The effects of acetone on NO removal from flue gas with different gas compositions and the function mechanism of acetone on NO removal were discussed. The results indicated that the NO removal efficiency decreased with the increase of O2 content in the NO/O2/N2 system, and the addition of a small amount of acetone could counteract the inhibition of O2 and improve the NO removal efficiency dramatically. In the NO/O2/N2/CO2 system, the increase of CO2 could reduce the NO removal efficiency, and the addition of a very small amount of acetone could reduce the inhibition of CO2 on NO removal significantly. In the NO/O2/N2/CO2/H2O system, the addition of H2O could reduce the NO removal efficiency, and the addition of small amount of acetone could greatly reduce the inhibition of H2O on NO removal. |
