油页岩在回转干馏炉内停留时间的综合分析

Comprehensive Analysis of Oil Shale Residence Time in Rotary Retorting

通过对油页岩在回转干馏炉内停留时间的影响因素进行的实验研究,结果表明:抄板形式、填充率、回转干馏炉倾角以及回转干馏炉转速4个因素对停留时间影响由强至弱依次为倾角、转速、填充率、抄板形式,最佳工况组合为回转干馏炉倾角4.33°、回转干馏炉转速4.8 r/min,填充率20%,直抄板。

In this work,the residence time of oil shale particle in rotary retorting is influenced by many factors,which include the lifting flight types,the vessel filling percentage,angle and the rotational speed of rotary retorting.According to high-low influence degree,the result indicates that the order of impact factor is the angle,the rotational speed of rotary retorting,the vessel filling percentage and the lifting flight types.The best combination is right-angled flights forms at 20%vessel filling percentage,4.33°dip angle with 4.8 r/min rotation speed and the mixing degree of rotary retorting.
