摘　　要：在氧化铝流态化焙烧炉系统中 ,采用气流干燥设备来脱除湿氢氧化铝的附着水。本文通过分析及研究气流干燥的过程 ,建立过程数学模型 ,运用计算机对给定的某氧化铝厂的文丘里干燥器进行计算 ,比较计算结果与实际值 ,以校核验证模型的正确性和可用性。In the Fluidized Bed System of the Alumina Calciner,the surface moisture of the hydrate is evaporated by pneumatic dryer. This article presents a method of mathematical model was established through analyzing and studying the process of pneumatically drying. The pneumatic dryer was calculated in an alumina factory of setting by using computer, and compares the results of calculation and actual values in order to check and prove the exactness and usability of the model. This model is of practicability and advantage even more than traditional model of pneumatic dryer on engineering application.
