Description

Technical Field

[0001] This utility model relates to the technical field of aluminum electrolysis equipment, and in particular to a heat dissipation balancing device for an aluminum electrolysis tank shell. Background Technology

[0002] In aluminum electrolysis, the principle of molten salt electrochemistry is employed, using a fluoride system (such as cryolite) as the molten salt, with electrolysis temperatures reaching approximately 950 degrees Celsius. The energy utilization rate of the aluminum electrolysis cell is around 50%, meaning about half of the energy is lost through the cell itself. This energy is dissipated through the upper and lower sides of the cell; however, the heat dissipation rates differ between the upper and lower parts, requiring control as needed; sometimes, insulation is also necessary. The heat dissipation from the side of the aluminum electrolysis cell shell is closely related to the cell's operation. Heat dissipation in the molten salt region is crucial for the formation of a solid furnace lining. This solid lining, formed by the crystallization of the fluoride molten salt, protects the internal structure, shell rigidity, and strength of the aluminum electrolysis cell, ensuring long-term stable operation. If the furnace lining is thin, side heat dissipation will be greater; conversely, if the furnace lining is thick, side heat dissipation will be less, while heat dissipation from other parts of the electrolysis cell will increase. These factors affect the operation of the electrolytic cell, leading to various adverse effects such as irregular furnace shape, large voltage fluctuations, unstable operation, reduced current efficiency, and increased energy consumption.

[0003] However, most existing large electrolytic cell shells use heat sinks welded to the side of the shell for heat dissipation. In this method, the position of the heat sink is fixed and cannot be adjusted or modified as needed. Alternatively, magnets can be used to attach the heat sink to the shell of the electrolytic cell. However, since the magnetic attraction is limited and the performance of the magnet will decrease or even demagnetize when used for a long time in a high-temperature environment, the heat sink may slide down or even fall off when it is fixed, which is not conducive to the long-term stable operation of the electrolytic cell.
