Description

Technical field: [0001] The invention relates to alumina production equipment, in particular to a dissolution device for alumina production. Background technique: [0002] Over the past ten years, my country's alumina industry has made great progress in large-scale equipment. At present, for the Bayer process alumina production system, the maximum production capacity of a production series can reach 400-450kt / a alumina, which is higher than that in the 1980s. more than 5 times. The large-scale equipment has greatly improved the production capacity and technical equipment level of my country's alumina plants, and the economic benefits have been significantly improved. [0003] Large-scale equipment is the development trend of the alumina industry at home and abroad. It can increase the production capacity of alumina plants, the level of automation equipment and labor productivity, improve technical and economic indicators, and reduce consumption. The newly-built Bayer proces...
