中文摘要：

采用自制回转窑换热装置对离心粒化后的高温炉渣颗粒进行余热回收,采用有限元分析软件及欧拉双流体模型对装置内气固两相流场进行数值模拟,研究进风风速及回转窑转速对气固换热效率的影响,并通过现场试验对模拟结果进行验证。结果表明,当回转体转速为16r/min、进风风速4.31 m/s时,颗粒的离散效果较好,热风温度达1 050K,此时的换热效果最好,数值模拟与试验结果高度吻合。

英文摘要：

Self-made rotary heat transfer device was applied to recover waste heat of high temperature centrifugal slag particles.Gas-solid phase flow was simulated by finite element analysis software and Euler model.The effects of inlet air velocity and rotating velocity of rotary kiln on heat transfer rate were investigated.The simulated result was verified by field test.The results show that the optimum heat transfer and dispersing effect are obtained under the conditions including rotator velocity of 16r/min and inlet air velocity of 4.31 m/s with hot air temperature of 1 050 K.Numerical simulation results highly coincide to experimental study.
