摘要
通过采用新母线设计理念、新式阴极钢棒结构、等量吸风烟道等技术,完成宁东节能型SY400铝电解槽的设计。分析了影响铝电解槽运行的关键因素:降低铝液和电解质流速可提高铝电解槽的稳定性,而等量吸风烟道可降低净化系统能耗。经过两年的生产实践和工艺优化,宁东节能型SY400铝电解系列在平均槽电压3.880 V条件下达到了93.7%的电流效率,吨铝直流电耗仅12 342 k Wh,全系列每年可产生经济效益近9 000万元。
The new design concept of bus bar, the double collector bars and equal suction technology were used in Ningdong SY400 reduction cell. The key factors about the running of the cell were analyzed. The velocity of liquid aluminum and electrolyte were decreased to improve the MHD stability. The equal suction technology can help to cut down the energy resumption of GTC system. After two years of technology optimizing, the current efficiency and direct current consumption reach 93.7% and 12 342 k Wh / t-Al at average cell voltage of 3.880 V. The economical benefit created by these cells can reach 900 million Yuan.
