蒸发是氧化铝生产的重要过程之一,它是平衡氧化铝生产过程中水分和杂质盐类的工序。不同的氧化铝生产工艺所产出的种分母液成分不同,蒸发过程排出盐类的成分及数量也不同。所以,不同的氧化铝生产工艺应采用不同的蒸发工艺及装置。在我国氧化铝行业中已采用的蒸发装置有标准式蒸 Evaporation is one of the important processes of alumina production. It is a process that balances the water and impurity salts in the alumina production process. Different alumina production process produced by the species of the mother liquor composition is different from the evaporation process of salt components and the amount is also different. Therefore, different alumina production processes should use different evaporation processes and devices. In our alumina industry has been used in the evaporation device standard steam
