Description

Technical Field

[0001] The utility model relates to the technical field of aluminum oxide production equipment, in particular to a new steam condensate treatment device for an aluminum oxide plant. Background Art

[0002] Alumina is mostly produced by wet smelting. During the production process, bauxite slurry and caustic soda undergo a high-temperature and high-pressure dissolution reaction in an autoclave to produce a high-temperature and high-pressure mixture of sodium aluminate and red mud. High-pressure dissolution is a relatively important process and usually uses a flash tank. The function of the flash tank is to fully release secondary steam from the material after high-temperature and high-pressure dissolution after several stages of flash distillation, so that the material temperature and pressure can be reduced.

[0003] Most of the common new steam condensate treatment tanks in alumina plants are of an integral tank structure, which makes it inconvenient to clean the inside. In addition, due to the long-term use of the device, a large amount of impurities will remain on the inner wall of the treatment tank, affecting the normal operation of the device and failing to meet the working requirements of condensate treatment. Therefore, a new steam condensate treatment device for alumina plants is proposed. Utility Model Content
