| 摘 要： | 本文建立了干法烟气脱硫反应的实验装置 ,对以氧化钙为脱硫剂的干法烟气脱硫反应进行了实验研究 ,并利用压汞仪分析反应过程中参与反应的固体颗粒的孔隙结构的变化情况 ,对干法烟气脱硫反应过程中的固体颗粒孔隙结构特性进行动态分析 ,揭示和确定了反应过程中固体颗粒孔隙结构变化规律和脱硫转化率。研究结果表明 ,孔隙结构 ,包括孔径分布、最可几孔半径等是决定和影响干法烟气脱硫反应的因素 ,其中孔隙率决定脱硫反应的最终转化率 ,孔隙分布则控制着反应的过程特性。

| Abstract: | A test apparatus of the reactions of dry desulphration of a flue gas was set up,and an experimental research on its reactions by taking CaO as a desulphurizing agent was also conducted.The results showed that the pore structures,including the proe size distribution, the radii of the most probable pores etc were the factors deciding and influencing the reactions of dry desulphuration of the flue gas, of which the porosity determined the final conversion rate of the desulphuration reaction whereas the pore distribution controlled the features of the reaction processes. |

| Keywords: | desulphuration of flue gas gas solid reaction pore structure and mass transfer |
