Design Description
Lianlv aluminium cell is the main equipment, the design in the analysis of a large number of literature and field research on the basis of aluminium cell structure of the design, electrolytic aluminum production process of the energy balance is calculated to familiar with the aluminum Electrolysis process, and in the calculation on the basis of major equipment selection and workshop graphic design and the total transport scheme for the plans. This paper also introduced the electrolytic process of physical and chemical reactions, electrolyte aluminum nature of the system, the start-up cell and conventional electrolysis processes and the basic principles of design workshops. Design selection of the aluminum electrolytic process of basic parameters, current intensity selection of 300KA, groove type selection of intermediate material four point feeding prebaked pot, and a control machine. The bus is four point of entry, current efficiency is 94%, the total production capacity of 180,000tons.
System design specification, drawing the electrolytic trough structure, workshop floor plan and process flow diagram, plete the study of aluminum electrolysis flue gas pollution and its control in writing.
