| 摘 要： | 实验研究了回转干馏炉内非等粒径油页岩与固体热载体颗粒群的混合行为，以回转干馏炉出口油页岩质量分数的样本变异系数作为混合指数。对2种填充率、2种抄板形式、2种倾角在5种转速的不同工况下出口的混合指数进行计算，对比分析了混合指数的变化趋势及不同影响因素的混合机理，得出20%填充率采用直角抄板在倾角为3.24°时混合度优于其它对应工况，以对流混合为主。

| Abstract: | A rotary retorting reactor was designed and built for studying the mixing behavior of particulate oil shale and granular solid heat carrier. The sample coefficient of variation（cv，%）of mass percent of oil shale at the rotary retorting outflow was taken as mixing index. Mixing index was calculated at different work conditions（2 percentages of vessel filling，2 types of lifting flight，2 vessel dip angles and 5 different rotating speeds）. Comparison and analysis the variation trend of mixing index and mixing mechanism showed that the mixing degree with right-angle lifting flight was better at 20% vessel filling and 3.24°dip angle and convective mixing played a major role. |
