Abstract
A potline for the electrolytic production of aluminium comprising at least two rows of reduction cells (1 and 2) with the cells arranged transversely in each row. The electric current is conducted to and from the end cells by three or more asymmetrically arranged supply bars (T) via a distribution bar (A,B,C,D) on each end cell, so that a net current is formed in the distribution bar, providing compensation for the magnetic influence from the rectifier field and end cell field.
Description
The present invention relates to the layout of harmful electromagnetic interference in and rectifier zone regional from the end solution groove at the terminal electrolytic cell place of potline for setoff, said potline comprises at least two row's reduction electrolytic cells, and the electrolytic cell in each row is transversely arranged.
Utilizing electric energy with efficient manner is crucial for the production economy of aluminum electrolysis process.Also having very, the important point is to want so that electric current first electrolytic cell from rectifier guiding one row, and from first electrolytic cell of this row's the contiguous row of last electrolytic cell guiding, and then from the arrangement of the bus various piece of last electrolytic cell guiding rectifier, can make the induced field in the electrolytic cell reduce to the most weak.
A kind of typical layout of aluminium cell is that the electrolytic cell among each row is laterally placed, and electric current flows to next electrolytic cell from an electrolytic cell, and from a current drainage to next row.Current opposite in direction during the sense of current among one row is arranged with contiguous one.
Electrolysis process of the present invention utilizes 200 to 300KA electric current.This electric current can induce the high-intensity magnetic field of the adjacent row of impact and adjacent electrolytic cell and cause various serious problems, because magnetic field can hinder motlten metal to form negative electrode at each bottom of electrolytic tank.Motlten metal can be subjected to flowing through owing to electric current the impact of the electromagnetic force that produces.
, the distance between two row's electrolytic cells of cell line is usually all far away, so that only have the vertical component in magnetic field that a contiguous discharge is given birth to effect.In order to compensate for caused harmful bias field component by a contiguous row, narrow end next door or the beneath current ratio of passing through towards a contiguous row is big by the electric current of other parts of electrolytic cell in transversely arranged electrolytic cell usually.
First of each row all is the electrolyzer that is subjected to disturbance of electromagnetic field maximum with last electrolyzer (terminal electrolyzer), because they both had been subjected to the influence from a contiguous row's magnetic field, be subjected to influence again from (endways between the electrolyzer) bus magnetic field, said bus conducts back rectifier to electric current from the end in pot line zone, and at the other end electric current is transmitted to next row's electrolyzer from row's electrolyzer.By increasing the distance between rectifier and the cell line, and increase (electric current) last electrolytic cell from a row and guide the distance of a contiguous row's horizontal bus into and can weaken this interference., owing to need long bus and bigger place, this is the method for a costliness.
The objective of the invention is and to reach sufficient setoff to the magnetic disturbance of the stub area at the terminal electrolytic cell place of the cell line that forms from rectifier zone and by aluminium cell row, another purpose then is to reduce assembly cost by reducing bus length, and by reducing the distance between rectifier and cell line one end, and reduce the distance between horizontal bus and the cell line other end and save space.
Above-mentioned purpose can reach like this, promptly as shown in the drawing, allow electric current in three above power source buss, be transmitted to the terminal electrolyzer of pot line asymmetricly or flow out from this end electrolyzer, produce net current in order to induction in distribution bus, thereby to recompensing from the magnetic interference of rectifier and stub area.
The present invention is only by example, include with reference to expression layout of the present invention pot line accompanying drawing and at length introduce.The present invention includes only the terminal electrolytic cell in row's electrolytic cell, and does not comprise full row's electrolytic cell.Should be understood that in addition the well-known technology that adopts, just can make and respectively arrange electrolytic cell itself and be not subjected to arrange the interference of electrolytic cell and reach stable from the neighbour.
In the accompanying drawing, label A represents the distribution bus of first electrolyzer of first row, B represents the distribution bus of last electrolyzer of first row, C represents the distribution bus of first electrolyzer of second row, D represents the distribution bus of last electrolyzer of second row, S represents the upright bus of distribution bus A, and T represents power source bus, and L represents rectifier.
Be transported to first terminal electrolyzer of first row from the electric current of rectifier L by three above power source buss, and asymmetric flowing to includes the distribution bus A of upright bus S more than four that arranges symmetrically with respect to electrolyzer.This layout just provides the net current that conducts from right to left in distribution bus A, and first terminal electrolytic cell of first row is afforded redress.Thereafter, electric current is transmitted to the anode of adjacent downstream electrolyzer from the negative electrode of upstream electrolyzer, and conducts to another terminal electrolyzer of first row in this way.
Electric current conducts to distribution bus B from this another terminal electrolytic cell.Electric current is from described electrolyzer three first electrolyzers that conduct to vicinity second row who is run into along the sense of current with Up Highway UHW T through arrange with respect to distribution bus B mid point asymmetricly then.This layout from left to right provides net current in distribution bus B, and provides essential extra compensation to this another terminal electrolytic cell of first row.
Electric current is further conducted to the second distribution bus C that ranked first on the electrolyzer asymmetricly.Its after-current conducts to the anode of adjacent downstream electrolyzer from the negative electrode of upstream electrolyzer, and conducts to another terminal electrolyzer of second row in this way.Electric current conducts to distribution bus D from this another terminal electrolytic cell of second row.As shown in the figure, electric current is again from this bus D, conducts through the bus T more than three that arranges with respect to the mid point of distribution bus asymmetricly and gets back to rectifier.
Obviously, be in the distribution bus in rectifier zone and the stub area, stand the size of bus and power source bus and position and will determine current strength in the distribution bus, and to the degree of compensation of terminal electrolytic cell.
When building and design the potline in the magnetic field that has high current intensity and weaken, consider that from various important factors and condition actual arrangement of the present invention can utilize normal building process to realize.Usually the terminal electrolyzer that has only electric current to surpass the pot line of 200KA just needs extra compensation.
