| 摘 要： | 回转窑内物料颗粒的横向运动使物料的传热和传质得到加强,其研究对于回转窑的优化设计和运行是十分重要的。本文在数学模型的基础上采用数码摄像的方法对多种物料颗粒在旋转筒体内的横向运动进行了实验研究,考察了筒体直径、旋转速度、料床内物料的动态休止角等参数对于泻落层厚度、颗粒运动速度、流量以及物料在料床表面停留时间的影响,并通过实验验证了数学模型。

| Abstract: | The transverse motion of particle enhances the heat and mass transfer of material in the rotary kiln, and it is important for the optimal design and practical use of the equipment. Based on mathematical model, this paper experimentally investigated the transverse motion of selected particles in the cylinder by using of video camera. The influences of cylinder diameter, rotating speed and dynamic angle of repose of the bed material on the thickness of cascading layer, velocity, mass flow rate as well as the residence time on the bed surface were studied, and the mathematical model was verified by results from the experiment. |
