板式降膜蒸发器在氧化铝生产中的运行情况

The Operation of the Plate Falling-film Evaporator in the Production of Alumina

在氧化铝生产过程中采用板式降膜蒸发器浓缩铝酸钠溶液是一种新的尝试,运行实践表明,板式降膜蒸发器的建设是成功的,但是,仍有一些问题有待解决。

Adopting the plate falling-film evaporator for concentrating sodium aluminate solution in the production of alumina is a new trail. The operating practice shows that the construction of the plate falling-film evaporator is successful, however there are still some problems to be solved.
