摘　　要：为了研究钴氨络合物烟气脱硝的传质系数,搭建了湿壁塔反应装置。通过改变进入湿壁塔内模拟烟气的NO和SO_2浓度、钴氨络合物的浓度、反应温度等,对钴氨络合物吸收NO的传质系数进行了实验研究。实验结果表明,当烟气中NO浓度和钴氨络合物浓度增加时,NO传质系数增大;当SO_2浓度增大时,NO传质系数减小。并且发现,钴氨络合物吸收NO的最佳反应温度为55℃。可为开发钴氨络合物同时脱硫脱硝技术提供参考。In order to study mass transfer coefficient of flue gas denitration by hexamminecobalt（Ⅱ） complex,a reaction device including wetted-wall column was set up. Experimental research on mass transfer coefficient of NO absorption was carried out by changing parameters of NO concentration, SO2 concentration, reaction temperature and hexamminecobalt（Ⅱ） complex concentration,respectively.The experimental results showed that the mass transfer coefficient of NO increased with the enhancement of NO concentration and hexamminecobalt（Ⅱ） complex concentration; the mass transfer coefficient of NO decreased with the rise of SO2 concentration. The optimal reaction temperature of NO absorption by hexamminecobalt（Ⅱ） complex was 55 ℃. Research results of this paper could provide a reference to developing simultaneous desulfurization and denitration technology by hexamminecobalt（Ⅱ） complex.
