Abstract
The invention discloses an electrolyte tank negative bar collocation method. It uses large-end face negative bar at electrolyte tank current inlet side, and much-less current inlet section at electrolyte tank current outlet side. The current flowed in flue end negative bar is bigger than in aluminum outlet end. And their current are respectively sent to middle riser bus and aluminum outlet riser bus. The invention resolves the defect of bad magnetic field compensation strength and bias current of current inlet outlet side bar in current technique. It is of great advantages to improve electrolyte tank magneto fluid mechanics and running stability. It has the advantages of simple operation, low investment, and obvious effect.
Description
Technical field:
The present invention relates in a kind of Aluminum Electrolysis Production process the collocation method of aluminium electrolytic cell cathode bus.
Background technology:
Along with modern prebaked anode cell continuous advancement in technology, and the further investigation of physical field and the foundation of relevant mathematical model in the electrolytic process, the design of electrolyzer is developed from the computer aided design (CAD) direction of experience to science.For bringing bigger economical efficiency, the production strength of current of aluminium cell constantly increases, and according to the description of Faraday's law, when other conditions equated, magnetic field will increase with the increase of electric current.Thereby the magnetic environment of melt is for guaranteeing that stably manufactured also becomes more and more important in the electrolyzer.For guaranteeing busbar system Magnetic Field Design reliability, must accomplish that in the design of bus section (electric physical field) bus-bar system various piece distribution of current is even, with prevent because of electrolyzer anode and cathode distribution of current inhomogeneous, make groove internal magnetic field distribution curve produce drift, change the flow condition of interior magnetic properties of groove and melt, cause the interface of melt in the electrolyzer to be fluctuateed, seriously disturb the ordinary production of electrolyzer.Cause the new instability of electrolyzer.In the large-scale design of giving the roasting groove, for the needs of engineering and reduce investment outlay, to consider that usually two row's electrolyzers produce series as one.Because therefore the directivity that exists pot line to arrange, in the busbar system design, must consider the current affects of adjacent row slot around electrolytic bath, thereby make electrolyzer flue side and go out the magneticstrength difference of aluminium side compensation, institute's strength of current of walking is also different.
With the electrolyzer medullary ray is the boundary, the left and right sides of electricity input side bus and electricity output side bus is as adopting identical busbar arrangement and specification, not only can cause the field compensation dynamics not enough, and can produce the bias current phenomenon, make groove internal magnetic field distribution curve produce drift, change the flow condition of interior magnetic properties of groove and melt, cause electrolyzer stability to wreck, bring very big harm to production operation.
Summary of the invention:
The objective of the invention is to: the collocation method of the aluminium electrolytic cell cathode bus of the not enough and electric current bias current phenomenon of a kind of field compensation dynamics that can effectively solve electrolyzer is provided,, overcomes the deficiencies in the prior art to guarantee the stably manufactured of electrolyzer.
The present invention is achieved in that its electricity input side at electrolyzer, to be arranged on flue end, and make by electricity input side and flow to the electric current of negative busbar of flue end greater than the electric current that flows to the negative busbar of aluminium inlet by electricity input side promptly near adjacent row's electrolyzer end be arranged on aluminium inlet and promptly adopt big section away from the negative busbar that the neighbour arranges the electrolyzer end; It will be arranged on simultaneously near the negative busbar at electrolyzer center and adopt light section, and make by electricity input side and flow to the negative busbar electric current of flue end greater than the electric current that is flowed to the negative busbar of aluminium inlet by electricity input side; Electricity output side at electrolyzer, it adopts the negative busbar less than the electricity input side section, and the electric current that will be arranged on the negative busbar of aluminium inlet is sent in the riser bus bar of aluminium inlet, the electric current that is arranged on the negative busbar of flue end is sent to the intermediate column bus, to guarantee the current balance type of whole riser bus bar.
Being arranged on aluminium inlet is 330cm with the end face that is arranged on the negative busbar of flue end
2～2000cm
2, the end face that is arranged on the negative busbar at close electrolyzer center is 35cm
2～300cm
2
At aluminium inlet and flue end, the current ratio that is flowed to the negative busbar of flue end by electricity input side is flowed to aluminium inlet by electricity input side the electric current of negative busbar is big by 10%～40%; Near the center of electrolyzer, the negative busbar current ratio that flows to aluminium inlet by electricity input side is flowed to flue end by electricity input side the electric current of negative busbar is big by 10%～40%.
Owing to adopted technique scheme, under the voltage condition such as utilization of the present invention, the relation principle that electric current and resistance (bus distance) are inversely proportional to, left and right sides negative busbar by electrolyzer electricity input side bus and electricity output side bus distributes asymmetric and negative busbar specification asymmetric of electric current, walk distance to advancing with the different magnitudes of current and electric current, electricity output side each several part bus adopts different size, different distributing style balances are advanced, the electricity output side electric current, make into, electricity output side electric current distributed uniform, electrolyzer internal magnetic field gradient is reduced, improved the homogeneity of magnetic fluid greatly, effectively solved the field compensation dynamics not enough and since the difference of distance advance, the phenomenon of electricity output side bus current bias current, hydromagnetics and the operation stability that improves electrolyzer there is certain benefit, it is simple to have configuration, less investment, the outstanding effect advantage.
