Dual current supply system for aluminum-producing electrolyzers

摘要

A dual current supply system for aluminum-producing electrolyzers longitudinally arranged in a series-connected row comprises at least four anode risers in each space between next-adjacent electrolyzers. The system includes anode systems and anode buses electrically connected to the anode risers for supplying current from the anode risers to the anode systems. Two of the anode risers of one of a pair of next-adjacent electrolyzers are coaxially positioned in the space between the next-adjacent electrolyzers and two of the anode risers of the other of the pair of next-adjacent electrolyzers are positioned in the space between the next-adjacent electrolyzers in coplanar relation with the anode risers of the one of the next-adjacent electrolyzers. The arrangement of the anode risers enables a more uniform distribution of the magnetic field and permits the total length of the electrolyzer body and current supply buses to be reduced.
