摘要
烧结法赤泥的沉降性能试验结果表明,选用适当的进料固含和絮凝剂,可以达到最佳的沉降效果;采用E-Duc稀释系统及多点加入方式,絮凝剂加入量为30～50kg/t,稀释倍数为8～10。高效沉降槽用于烧结法赤泥的分离、洗涤,提高了运转率和产能,简化了生产流程,优化了技术指标,年经济效益280余万元,达到增产降耗的目的。
The settling performance test of digestion red mud in the alumina production with sintering process and the application of high-efficient procipitation tank in the red-mud separation and washing are introduced. The settlement test results show that the best settling effect can be achieved by selecting proper solids content in the feeding and flocculants. Adopting E-Duc dilute system and multipoint input method, - 50kg/t flocculants and 8 - 10 dilute multiple, the application of high-efficient precipitation tank improves the operating rate effectively, simplify the production procedure, optimize the technical indexes, has the year economic efficiency in 280 ten thousand Yuan and realizes increasing the output and decreasing the consumes .
