Background technology
Along with the development of China's aluminum i ndustry production technology, the resource of bauxite is more and more nervous, needs to adopt new resource.At present, some areas flyash aluminium content is up to 40 ~ 60%, this is a kind of very important non-traditional alumina resource, and from aluminous fly-ash, extract aluminum oxide, to alleviating flyash environmental pollution, expand Ash Utilization approach, expanding China's aluminum oxide industry raw material sources has positive effect.The aluminum oxide extracted from aluminous fly-ash needs special modern large-scale aluminum electrolytic cell to carry out series of experiments, this is not only because will understand, adapt to the performance of this aluminum oxide, also need a set of production technique matched with it, therefore need special experimental cell.
At present, Faradaic current powerful in electrolyzer is transported on electrolyzer by the direct current after rectification by aluminium busbar, and to be together in series formation series by aluminium busbar between electrolyzer.And the electromagnetic force that in magnetic field and electrolyzer that the production electric current of electrolyzer produces, melt Interaction Law of Electric Current produces makes melt cyclical acceleration in groove, cause that liquid aluminum generation is swelled, deflection and fluctuation, even may affect electrolyzer can not normally produce.Therefore in order to realize the stable of electrolyzer magnetic fluid, in potroom busbar require affect electrolyzer administration measure important factor---groove internal magnetic field distribution character (requires that magnetic field value is little, gradient is little) become even more important, and also bus-bar system various piece homogeneous current distribution must be accomplished in the design of bus section (electric physical field), to prevent because electrolyzer anode and cathode distribution of current is uneven, groove internal magnetic field distribution curve is made to produce drift, cause the interface of melt in electrolyzer to be fluctuated, have a strong impact on the normal production of electrolyzer.
Due to test potroom only four large-scalely give roasting groove, in potroom busbar system design, must consider how to return rectifier from electrolyzer bus out, the design adopts and returns rectifier from electric currents such as electrolyzer two ends, thus making electrolyzer flue side and go out aluminium strength of current that side is walked identical, the magneticstrength of compensation is also identical.Namely with electrolyzer medullary ray for boundary, the left and right sides of electricity input side bus and electricity output side bus adopts identical busbar arrangement and specification.
Summary of the invention
The technical problem to be solved in the present invention is, there is provided a kind of to consider from technology, economy, for the bus-bar collocation structure of test potroom, more reasonably to design large-scale aluminum electrolytic cell field compensation scheme, make it can obtain good field compensation effect, bus consumption around groove can be saved again, thus overcome the deficiency of prior art existence.
The present invention is formed like this:
1) test potroom and configure 4 electrolyzers, 4 root post buses of First electrolyzer are connected with the current enter bus A-1 introduced from rectifier, and wait current bus bar and current output terminal bus A-2 that 4 false riser bus bars of the 4th electrolyzer are equal apart from electrolyzer longitudinal center with two groups connect and connect rectifier;
2) 4 root post buses and 36 cathode soft bus are set, pass in and out electric zygomorphy and distribute; 4 root post bus geometric ratios enter electricity;
3) negative busbar of electrolyzer electricity input side adopts big cross section, and electricity input side electrolyzer two ends cathode soft bus is connected with the intermediate column bus of downstream slot; In the middle part of electricity input side, cathode soft bus is connected with the termination riser bus bar of downstream slot;
