The utility model designs a distribution of the busbar around and underneath the electrolytic bath, ensuring the vertical component in magnetic field of super large electrolytic bath (500K-600KA) appears to be comparatively low, and establishes the best current sharing ratio of the busbar around and underneath the electrolytic bath.
Description
Technical field
A kind of ultra-large type aluminum cell bus-bar structure relates in a kind of aluminium electrolysis process, ultra-large type aluminum cell bus-bar structure.
Background technology
Aluminium electrolytic industry is the industry of energy-intensive, energy-saving and cost-reducing be always and be aluminum electrolyzation technology progressive theme with continuing.Nearest two more than ten years, the main trend that aluminium cell maximizes, large becomes international aluminum electrolyzation technology development leads world aluminum industry to develop towards producing low cost, resource low consumption, refuse low emission and product high quality direction.With French Pechiney Chinalco is representative, rely on specialized commerical test base, adhere to walking the integrated technology route, succeed in developing AP18, AP30 and AP50 aluminium cell complete set technology leading in the world in succession, in the aluminium production capacity of west, form 20% share, become the pioneer of modern electrolytic aluminum industrial technology.
The electrolytic aluminum process be in electrolyzer by the smelting process of powerful direct current to aluminum oxide because electrolyzer inside has powerful electric current to pass through, around electric current, certainly lead to magnetic field.Concerning Aluminium Electrolysis, major concern be Distribution of Magnetic Field in melt metal aluminium one ionogen because it is the principal element that influences the flow field.The principal element that produces this part magnetic field has: the magnetic field that all current carrying bus of (1) groove produce in groove; (2) magnetic field of groove inner wire (comprising guide rod, steel pawl, anode and cathode carbon piece, melt, cathode steel bar etc.) generation; (3) influence of ferromagnetic substance (pot shell, groove upper mechanism etc.); (4) magnetic field of in this groove, producing of upstream and downstream groove, adjacent row groove etc.The influence of all the other factors such as ferromagnetic substances such as workshop steel structure, overhead traveling crane is less, can ignore.In order to design the large-scale aluminum electrolytic cell of high current efficiency, the electromagnetic force of necessary weakening and control flume internal magnetic field and Interaction Law of Electric Current.
Summary of the invention
The present invention be directed to the ultra-large type (Magnetic Field Design of 500～700KA) electrolyzers, provide a kind of bath circumference bus and bottom land bus distribution mode that can guarantee that ultra-large type electrolyzer magnetic field vertical component is less, the ultra-large type aluminum cell bus-bar structure that the bath circumference bus and the ratio of sharing electric current of bottom land bus are optimized.
The purpose of this utility model is achieved through the following technical solutions.
A kind of ultra-large type aluminum cell bus-bar structure is characterized in that its structure is to adopt i.e. 72 outflows in two ends of 36 negative electrodes; Its total current adopts 7 end columns to distribute the electric mode of advancing of electric current; It is 2～3 that bath circumference bus is shared the ratio that electric current and bottom land bus share electric current.
A kind of ultra-large type aluminum cell bus-bar structure of the present utility model, it is characterized in that the described electric mode of advancing, article 4, bath circumference bus thoughtfully descends the platform trough column from two groove respectively, article two, the bottom land bus passes electrolyzer to following platform trough column through bottom land in two respectively, and intermediate column only connects the electric current that B face rod iron comes out.
A kind of ultra-large type aluminum cell bus-bar structure of the present utility model, electric current is from i.e. 72 outflows in two ends of 36 negative electrodes of a last electrolyzer, distribute by bus current, enter next electrolyzer through 7 end columns, it is 2～3 that its end grooves circumference bus is shared with sharing current division ratio by the bottom land bus, can guarantee that (less bath circumference bus and the bottom land bus distribution mode of magnetic field vertical component of 500K～600KA) determined the ratio of sharing electric current of best bath circumference bus and bottom land bus to the ultra-large type electrolyzer.
