Description
Technical field
The present invention relates to a kind of aluminum cell bus-bar structure, more particularly to a kind of configuration of aluminum cell bus-bar aluminum cell current from balanced bus networks structure.
Background technology
Since the nineties in last century, the development of world aluminum cell technologies is fast, characterizes the advanced important indicator current strength of aluminium cell and has developed into 600kA from 160kA.Aluminium cell is a direct current electrochemical reaction appts, the electric current passed through and distribution it is stable be aluminium cell can efficiently, the deciding factor of stable operation.Aluminium cell is such conduction electric current, electric current flows out from upstream slot cathode sets, flow through bus around upstream slot, then this groove riser bus bar is come together in, anode unit is flowed into by the balance bus for the big bus of anode large bus bar and jointed anode for hanging anode unit, again by the electrolyte of molten condition, aluminium liquid, finally exited into from this groove cathode sets to next electrolytic cell.
Aluminium liquid is the good conductor of electricity, may be regarded as equipotentiality body under normal circumstances, plays a part of even level's electric current.And compared with aluminium liquid, the resistivity of electrolyte is the 10 of aluminium liquid4Times, do not have horizontal current substantially and occur in the electrolyte.Due to the good electric conductivity of aluminium liquid, upstream cell current passes through the distribution of aluminium liquid equipotentiality body, and the electric current flowed out from each cathode sets of upstream slot is relatively uniform, after this groove dielectric substrate is reached, because resistance is big in dielectric substrate pole span, the electric current for flowing through each anode unit is also relatively uniform.In actual production process, aluminium cell inevitably fluctuates, either concentration control out of control, thermal balance regulation unstability, manual operation or accidental factor cause, and it is unbalance that the essence of fluctuation can be attributed to electric equilibrium, and volatile magnetic fluid is further caused by electric equilibrium is unbalance.The severe fluctuation such as anode effect or the big swing of aluminium liquid, in addition to influenceing this groove, also affects adjacent electrolytic cell.See from production practices, there is severe fluctuation or even influences the situation of adjacent cell happening occasionally in aluminium cell, and compared with general fluctuates, eliminate such fluctuation difficulty it is bigger, it is necessary to time it is longer, the harm thereby resulted in is just bigger.Therefore, it is necessary to taken seriously and solved.
The content of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of aluminum cell current from balanced bus networks structure, it is therefore an objective to reduces anode effect or aluminium liquid is big the influence badly fluctuated to this groove and its adjacent aluminium cell such as swings.
A kind of aluminum cell current of the invention is from balanced bus networks structure for the above-mentioned purpose, the anode large bus bar of insertion is set respectively in aluminium cell long axis centerline both sides, the anode large bus bar of both sides is connected by balance bus, the anode large bus bar of side is connected with branch road bus around groove and intermediate equilibria bus respectively by riser bus bar, the single riser bus bar loop of each bar is connected and forms a bulk loop by intermediate equilibria bus, in entering for aluminium cell, electricity output side respectively sets groove surrounding cathode bus, groove surrounding cathode bus connects negative electrode soft ribbons, branch road bus is connected with groove surrounding cathode bus around groove, intermediate equilibria bus and/or groove surrounding cathode bus are insertions.
Anode large bus bar, intermediate equilibria bus and any part of groove surrounding cathode bus of insertion can not be cut off, and be made up of a complete conductors, or are made up of segmented conductor connection.
The current density of connector is not higher than the current density of segmented conductor between segmented conductor.
The anode large bus bar of insertion decides whether to be segmented according to the quantity of anode lifting mechanism, and for a set of hoisting mechanism, one side has two suspension centres, and anode large bus bar is not segmented, and for a set of above hoisting mechanism, one side has two or more suspension centre, anode large bus bar segmentation.
Electric tank working electric current is in 160 ~ 800kA.
Advantages of the present invention effect：The present invention is using intermediate equilibria bus as tie, to the single riser bus bar loop of each bar in the prior art, it is changed into a bulk loop, anode large bus bar, the groove surrounding cathode bus of insertion are set simultaneously, bus-bar system is improved to interconnect ability, in the case of the severe fluctuations such as the big swing of anode effect or aluminium liquid, it is effectively conducted the abnormal high current triggered by severe fluctuation, conduction and generation harmful level electric current of these electric currents in electrolytic cell in aluminium liquid, and the adjacent cell fluctuation thereby resulted in are avoided to greatest extent.
