Abstract

The invention discloses a multi-chamber aluminum electrolysis tank and a bus system thereof. Anodes and cathodes are arranged in the multi-chamber aluminum electrolysis tank in an alternating manner in the horizontal direction. Platy electrode structures of the same size are adopted in the anodes and the cathodes. The anodes and the cathodes are vertically parallel to each other and fixed into theelectrolysis tank. At least two electrolysis chambers are formed between the adjacent anodes and the cathodes. Anode guide rods of all the anodes in the aluminum electrolysis tank are connected in parallel and collected to the same anode bus. Horizontal flow collecting steel bars of all the cathodes in the aluminum electrolysis groove extend out of the same side of the aluminum electrolysis tankand are connected in parallel and collected to a stand column bus through cathode buses. The stand column bus is connected to a power source negative pole or connected into an anode bus of the next electrolysis tank in series. The anode bus is connected to a power source positive pole or connected into a stand column bus of the former electrolysis tank connected in series. The aluminum electrolysis tank has great significance for energy conservation and economic operation, and guarantee can be provided for deep energy conservation and environmental protection.

Description

technical field [0001] The invention belongs to the aluminum electrolysis technology, in particular to an economical aluminum electrolytic cell busbar structure with single-side electricity output. Background technique [0002] The Hall-Héroult aluminum electrolysis process has always been the only method for industrial aluminum smelting, and its core reaction is carried out in the aluminum electrolytic cell. [0003] In the aluminum electrolysis series, all the electrolytic cells are connected in series, and the bus bar mainly undertakes the function of transmitting the current from the cathode rod of the upstream electrolytic cell to the anode rod of the downstream electrolytic cell. At the same time, the bus bar of the electrolytic cell, especially the cathode bus bar, plays a decisive role in the stability of the electrolytic cell. Different cathode configurations will produce completely different magnetic field configurations and stability. In addition, the cost of the...
