Layout method of decomposing and grading system and corresponding water circulating system in aluminium plant

Abstract

The layout method of decomposing and grading systems and corresponding water circulating systems in aluminum plant includes setting two corresponding water circulating systems in every two decomposing and grading systems within the same production area. The present invention has shortened water circulating pipeline, reduced underwater pipeline, simplified construction, lowered power consumption and production cost and other advantages.

Description

technical field [0001] The invention relates to a decomposition and classification system of an aluminum plant and a layout method of a corresponding circulating water system, and belongs to the technical field of the layout and configuration of the decomposition and classification system of an aluminum oxide plant and circulating water system equipment. Background technique [0002] The decomposition and classification system is one of the key processes in the production of alumina by the Bayer method. In the process of decomposition and classification, it is very important to control the appropriate temperature. In order to achieve the purpose of decomposition temperature control, a circulating water system is generally used to cool the decomposition tank through water. The internal flowing solution reaches a predetermined temperature to meet production requirements. Generally, in the general layout of an aluminum factory, the decomposition and classification system and th...

Problems solved by technology

Generally, in the general layout of an aluminum factory, the decomposition and classification system and the circulating water system are classified into different factory production areas, the decomposition and classification section belongs to the production area, and the circulating water section belongs to the auxiliary production area. It can also be applied to the expansion planned factory, but for a modern large-scale alumina production factory, when considering the general layout of the factory area, if the decomposition and classification system is still in accordance with the conventional design concept and method, the decomposition and classification system and the corresponding cycle The water system is arranged in different plant areas, which will inevitably increase the laying length of the circulating water system pipeline, the area of ​​the plant area and the transmission energy of the cooling water; in addition, the water pipes of the circulating water system must pass through a long plant area if they are not in the same area. Reach the corresponding decomposition and classification system, resulting in difficulties in the layout and construction of underground pipelines in the plant
