摘　　要：根据卧式内外间接加热脱溶器(HCD脱溶器)的工作原理,建立了HCD脱溶器的传质单元模型。模型包括含溶粕在降速脱溶阶段的固气两相运动速率、平衡关系、传质速率、含溶粕在脱溶器内的聚集状态,以及达到一定脱溶要求所需的脱溶段长度。该模型可用于对浸出粕脱溶实验数据进行关联,用于HCD脱溶器的设计与选型,亦可用于对HCD脱溶器的操作运行过程进行监控。According to the principle of the horizontal cylinder desolventizer (HCD) with indirectheating surfaces of inside and outside surfaces, a mass transfer unit modeling was proposed. The modeling contained a number of parameters, describing the behavior of the marc desolventization during the fallingrate periods in the HCD desolventizer, such as the movingrates of the solid and the vapor phases, the equilibrium relationship and mass transfer rate between the two phases, the void fraction of the solid phase within the HCD desolventizer. The modeling could be applied to the correlation of parameters in a marc desolventizing experiment, the design and selection of an industrialscale HCD desolventizer and the control of a HCD desolventizer in operation.
