Embodiment 1

[0016] The present invention is applicable to the configuration of the bus bar of the super-large aluminum electrolytic cell, which is realized by adopting a large-area multi-point power supply method.

[0017] In large-scale electrolytic aluminum processing, the electrolytic cell system is usually composed of two or more rows of single electrolytic cells connected in series, and the number of electrolytic cells in each row can be determined according to actual needs. Such two or more rows of electrolytic cells are adjacent to each other, and there is a certain degree of electromagnetic interference between the adjacent cells, which has an impact on the stable production of electrolytic aluminum. In the present invention, the electromagnetic interference between electrolytic cells in the same row and between each electrolytic cell and cells in adjacent rows is reduced through the configuration of the bus bars of the electrolytic cells, so as to ensure the stability of productio...

Embodiment 2

[0028] figure 2 It is the way in which the anode column busbar 11 and the anode balance busbar 16 are completely equidistantly arranged. After calculation, this way is not much different from the average value of the magnetic field results in Example 1, but the maximum value appears within the range of the anode projection, and its stability Weaker than Example 1.

[0029] The asymmetric layout of the cathode bus bar, multi-layer detour around the tank, anti-symmetrical introduction of the column bus bar of the lower platform, and the outward movement of the column bus bar and the anode balance bus bar in the present invention solve the problem of series current between 550kA and 700kA. The magnetic field configuration problem of the first-level ultra-large electrolyzer. This ensures the stability of the aluminum electrolytic cell production.

Abstract

The invention discloses a busbar configuration structure for an aluminum cell, which belongs to the technical field of metallic aluminum electrolysis. The busbar configuration structure for the aluminum cell comprises an upstream cathode busbar which is arranged on the upstream end of the cell, a downstream cathode busbar which is arranged on the downstream end of the cell, an anode mast and an anode mast busbar which is arranged between the anode mast and an anode busbar, wherein partial upstream cathode busbar passes through the bottom of the cell and arrives at the downstream side to become a cell bottom compensating busbar; partial upstream cathode busbar respectively passes by both ends of the cell and arrives at the downstream side to become a cell circumference compensating busbar; and the cell bottom compensating busbar and the cell circumference compensating busbar join up with the downstream cathode busbar. The busbar configuration structure for the aluminum cell solves the problem of electromagnetic disturbance between electrolytic cells and between electrolytic cells and electrolytic cells of adjacent rows, so as to realize optimum magnetic field distribution and stability of fused masses in the cells.

Description

technical field [0001] The invention relates to a current supply device for an aluminum electrolytic cell, in particular to a bus bar configuration method for an ultra-large aluminum electrolytic cell. Background technique [0002] With the improvement of aluminum electrolytic cell design and operation technology level, the newly designed and constructed aluminum electrolytic cell at home and abroad is increasingly developing in the direction of large-scale. However, with the increase of the series current, the influence of the magnetic field distribution generated by the current-carrying busbar and the melt current on the stability of the slot production and operation becomes more and more prominent. [0003] Therefore, in the design of large and super-large current tank busbars, its influence on the stability of the tank must first be considered. Through the analysis of the stability theory, we can know that in order to obtain good production stability of the aluminum ele...
