<p>A method for allocating higher and lower cathodes of an aluminum electrolytic cell in an energy-saving way is disclosed, in which cathode carbon blocks and cathode steel bars (3) are arranged at the bottom of the aluminum electrolytic cell, and the cathode carbon blocks are formed by alternatively mounting higher cathode blocks (1) and lower cathode blocks (2) with different thickness. The parts of the higher cathode blocks (1) higher than the low cathode blocks (2) shall be chamfered or cambered on both sides, such that a good effect of fluid resistance can be obtained. The stability of the interface between the aluminum solution and the electrolyte is properly improved in the aluminum electrolytic cell, and then the polar distance is effectively reduced during normal production. A lower working voltage thus obtained in the electrolytic cell will in turn lead to an effect of saving and reducing energy consumption.</p> |
