山铝电解铝厂电解槽设计特点

山铝电解铝厂在技术改造中采用200kA预焙阳极电解槽取代60kA自焙槽,该槽型具有优异的磁流体稳定性,合理的电热场设计,采用了窄加工面、阳极升降、“船形”槽壳、实腹板梁等多项先进技术和高性能的内衬材料。目前,电解槽已连续生产986天,电流效率达到了94.5%,吨铝直流电能消耗13100 kW.h,氟化氢和粉尘等主要污染物排放量全部达到了国家排放标准。

Design Characteristics of the Electrolytic Tank in the Electrolytic Aluminum Plant of Shanlv

200kA prebaked anode cell is adopted by in the Electrolytic Aluminum Plant of Shandong Aluminum Co.,Ltd instead of 60kA self-baking cell in technical modification.This prebaked anode cell has excellent magnetohydrodynamic stability and reasonable electric heating field design and adopts new techniques such as narrow treating surface,the anode rise and drop,ship-pattern pot shell and solid web plate girder;and inner lining of high performance.The electrolytic tank has kept running for 986 days up to now,the power yield reaches 94.5 %, while the direct electric power consumption is only 13100 kW.h,furthermore,the discharge of main pollutants such as hydrogen fluoride and dust etc is up to the national effluent standard.
