ALUMINUM ELECTROLYZER BUS ARRANGEMENT Russian patent published in 2006 - IPC C25C3/16 

FIELD: electrolytic production of aluminum; arrangement of electrolyzer buses.

SUBSTANCE: bus arrangement of aluminum electrolyzer at longitudinal position of electrolyzers in body has cathode rods connected with cathode bus stacks located on longitudinal sides of electrolyzer; each of them consists of at least one cathode bus, input and output anode risers connected with cathode bus stacks by means of connecting buses and with anode buses by means of transmitting buses. Anode buses are provided with jumpers at input and output and with additional jumper. To obtain the required current load on anode mass of subsequent electrolyzer, current load supply electric circuits have differentiated electric resistance. Bus arrangement may be made of four risers: two input risers are located at input end face of electrolyzer in projection of its cathode arrangement and two output risers are located on logitudinal sides at distance from central transversal axis of electrolyzer equal to 0.05-0.16 of electrolyzer length; bus arrangement is made at the following distribution of current load among risers, %: LH input riser, 15-35; RH input riser, 10-40; LH output riser, 15-35 and RH output riser, 10-40.

EFFECT: optimization of electromagnetic characteristics of process, optimization of metal and electrolyte circulating rate; improved parameters of process.
