| 摘 要： | 目前，全世界生产的氧化铝有90％是采用拜耳法生产的。1992之后国内少数铝厂开始采用“管道预热一压煮溶出”和“管道化高温溶出”间接加热溶出技术及装备。自2003年以来这两种溶出技术得到了优化和改造，并广泛应用于工厂生产。本文在实际生产数据和物热平衡计算的基础上，结合理论分析，论述了管道加热一停留罐溶出技术，管道预热一压煮溶出技术及管道化高温溶出技术所适用的不同工况。总结出管道加热一留罐溶出技术是溶出技术中最优的技术。

| Abstract: | More than 90 percent of alumina was produced by Bayer Process. Bushing Preheating- Autoclave Stripping Process and Channelization High- temperature Stripping Process were used by few alumina plants. These stripping processeswere optimized and they were applied by many alumina plants since 2003. Based on the data of the field- work and the material - heat balance method and combined the theories, Bushing Heating- Retention Tank Stripping Process and Bushing Preheating- Autoclave Stripping Process and Channelization High- temperature Stripping Process were expounded and compared. And the Bushing Heating- Retention Tank Stripping Process is the best process. |
