摘    要:以氧化铝生产流程的基准物流图概念为基础, 构筑了拜耳法生产氧化铝流程的基准物流图, 为定量分析拜耳法流程中物流对能耗的影响提供了一个比较的基准,并以某拜耳法氧化铝厂生产数据为依据, 绘制了该厂的实际物流图, 构筑了与其相对应的基准物流图。 用基准物流图法定量地分析了各个工序的工序能耗变化和折合比变化对氧化铝综合能耗的影响,以及生产流程中物流对能耗的影响, 为指导该厂今后的节能降耗工作提供了定量的依据。

Abstract: Based on the concept of standard materials flow diagram (SMFD) of alumina manufacturing process, the SMFD of alumina manufacturing process by Bayer method was constructed. A comparative benchmark for analyzing the influence of material flow on energy intensity was provided. On the basis of the data of an alumina manufacturing plant by Bayer method, the real material flow diagram of this plant was drawn and the SMFD was constructed accordingly. The influence of the change of the unit process energy intensity and the alumina-process product-ratios on the overall energy intensity and the influences of material flow in a manufacturing process on its energy intensity were analyzed quantitatively as an example.
