摘　　要：容积换热系数是决定回转圆筒干燥器载热体向物料传热的主要因素。在设计任务给定后,确定了设计所需的基本参数。进行了物料衡算和热量衡算,解决了需要消耗多少干燥介质和热量的问题。依据物料衡算和热量衡算的结果计算并确定了设备的规格参数。本文从容积换热系数入手,结合油页岩干燥的工程实例,对直接加热转筒式干燥机参数(筒体直径、长度)进行了理论设计计算。The volumetric heat transfer coefficient is the main factor to decide heating medium transferring heat from rotary drum dryer to material. Determined the basic parameters needed for the design after design task was given. Conducted the material balance and heat balance and solved how many drying medium and heat need to consume. Calculated and determined the equipment specification parameters according the balance results. In this paper, We studied from the volumetric heat transfer coefficient combined with engineering example about oil shale drying, and calculated the direct heating rotary drum dryer parameters with theoretical design, such as cylinder diameter and length.
