摘　　要：回转式烘干机因其适应性强而广泛应用于各类颗粒物料的烘干,其中三筒回转式烘干机更具优越性及广阔的市场前景,但其回转装置关键结构参数普遍存在以下问题:内筒及中筒尺寸不科学,导致烘干效率较低,流体运行阻力大,物料易堵塞;三层筒体的钢板厚度不合理,磨损不均匀,尤其外筒磨损特别严重。本文对回转装置进行了传热学、两相流运动学及三层筒体磨损规律的分析,并从工程应用角度提出了其关键结构参数的具体确定方法。In industry rotary dryers are widely used for drying all sorts of particle materials due to their adaptability, of which three-cylinder rotary dryers have the superiority and broad market prospect, but the following unreasonable problems still exist in the determination of key structural parameters of rotary device： the sizes of inner and middle cylinder are not scientific, resulting in low drying efficiency, great fluid running resistance and easy blockage of materials. The steel plate for three-cylinder is unreasonable in thickness with uneven wear, especially the outer cylinder wearing more seriously. The heat transfer, two-phase flow kinematics and three-cylinder wear law for the rotary device are analyzed and the specific methods of determining key structural parameters are proposed separately from a point view of engineering application.
