摘　　要：本文介绍了氢氧化铝浆液水力旋流器的工作原理,并针对某铝业公司氧化铝生产线晶种分解工序旋流器使用年限过长、结疤严重、分级效果不好、动力消耗大等生产实际情况进行节能技术改造。经过设计和选型计算,确定了水力旋流器的各种参数,选用1组处理能力为600 m^(3)/h的氢氧化铝浆液水力旋流器替代原有的2台旋流器,合理优化布置新旋流器,停用非必要的耗电设备,精简了晶种分解工序。工序优化后,每年可节约成本约188.5万元,并实现氢氧化铝浆液的高效分级。The working principle of aluminum hydroxide slurry hydrocyclone was introduced,and the en-ergy-saving technical transformation was carried out according to the actual production situation of alumina production line in an aluminum company,such as long service life,serious scarring,poor classification effect and large power consumption.After design and selection calculation,various parameters of the hydrocyclone were determined.A group of aluminum hydroxide slurry hydrocyclone with processing ca-pacity of 600 m^(3)/h was selected to replace the original two groups,and the new hydrocyclone was reason-ably optimized.The seed decomposition process was simplified by removing unnecessary power consump-tion equipment.After process optimization,the cost can be saved about 1.885 million yuan per year,and the efficient classification of aluminum hydroxide slurry can be realized.
