结晶浓缩沉降槽设计及在氧化铝生产流程中应用

Design of crystallization settler and its application in alumina production

在氧化铝生产流程中,沉降槽设备主要用于赤泥的分离、洗涤及氢铝沉降等,沉降槽首次应用在氧化铝蒸发工序,作为结晶浓缩的关键设备,进行碳分母液的结晶析盐获得成功。本文较详细地介绍了结晶浓缩沉降槽的创新设计及实际应用情况。

The settler is mainly used in separation and washing of red mud and settling to hydrate in alumina production. However, it is firsdy used in evaporation as main equipment for successful crystallization settling. The paper presents the design of crystallization settler and its application in detail.
