Abstract
An aluminum electrobath series of busbar device with several rows of deoxidizing electrobaths, in which, the cathode collecting busbar B-[1], and B-[2] are respectively arranged every long edges under the electrobath, the current may reach to the next electrobath from the B-[1] farest from the next electrobath through two busbar K-[1],K-[6] at the short end of electrobath and two busbars (K-[2],K-[5]), four (K-[2],K-[3],K-[4],K-[5]) or more busbars under the electrobath. The cross section of two busbars K-[1],K-[6] at the short end of electrobath may ensure them to conduct the current 2 times more than that arranged under the electrobath.
Description
The present invention relates to be used for the arrangement of busbars of potline, this series comprises many row's reduction electrolyzers, transversely arranged these electrolyzers in every row, more particularly, the predetermined electric current that passes described bottom of electrolytic tank conduction electrolyzer of described arrangement of busbars.
Usually these electrolyzers in the potline are arranged according to above-mentioned way.Row-to-row distance, or say more accurately, the distance between row's the medullary ray is from 30 meters to 50 meters.It is useful that these electrolyzers are arranged in two or more rows, so just can save the extra bus-bar that is used to reflux.Current direction among the two adjacent rows is reciprocal.
Use is these row's magnetic influence each other of reduction electrolyzer up to the serious problems of the large-scale aluminum electrolytic cell series existence of the electric current of 300KA, thereby the molten metal that constitutes negative electrode at each bottom of electrolytic tank is subjected to passing owing to electric current the influence of the electromagnetic force that described metal causes.In order to compensate for the vertical vector in the unwanted magnetic field that causes by main adjacent row, general importing than the more electric current of other narrow end surface in the face of near described adjacent row's the narrow end surface or its bottom at these electrolyzers.This is to have obtained Patent right well-known method.Utilize this known solution might make vertical magnetic field be symmetrical in the unitary longitudinal axis of each groove and transverse axis, but, the absolute value in magnetic field is easy to rise to more than 30 Gausses, sometimes greater than 100 Gausses.
In addition, described known solution is with more bus-bar, thereby will increase capital cost.
The purpose of this invention is to provide the way of the absolute value of reduction/minimizing vertical magnetic field as much as possible, well and stably move with the described reduction electrolyzer that guarantees potline.Further aim of the present invention is the magnetic influence of eliminating from main adjacent row, and reduces the number of employed bus-bar, thereby reduces investment cost.
According to the present invention, realize the method for above-mentioned purpose: negative electrode current collection bus-bar is set under these electrolyzers, and, from being arranged on from next electrolyzer described negative electrode current collection bus-bar farthest, have bigger horizontal area via two bus-bars in the narrow end surface outside that is arranged on these electrolyzers separately and each root of being arranged in couples under these cell bottom two, four or the more bus-bars, this makes electric current that their can conducting double under these cell bottom other each root bus-bar approximately.
In a most preferred embodiment, at two bus-bars of beneath configuration of above-mentioned these electrolyzers, these two bus-bars are arranged on the appropriate location near the narrow end surface of these electrolyzers.
In another most preferred embodiment, at four bus-bars of beneath configuration of above-mentioned these electrolyzers, wherein two are configured in the narrow end surface place, and other two are configured in the narrow end surface of described electrolyzer and the mid-way between the transverse axis separately.
Below will further introduce the present invention by embodiment and with reference to accompanying drawing, in the accompanying drawing:
Fig. 1 illustrates the vertical cross section that passes the embodiment that the reduction bottom of electrolytic tank draws electric current,
Fig. 2 schematically illustrates the vertical view of the arrangement of busbars that is used for these electrolyzers.
Among the figure: A is an anode, and C is a carbon cathode, and R and F are connection conductors, and I is a cathodic bus bars, and B1, B2 are electric current current collection bus-bar, and K1-K6 is a bus-bar, and S1-S5 is a bus-bar of receiving next electrolyzer.
In electrolytic process, electric current is introduced from anode A, passes electrolyzer and melt metal, continues to be passed down through two steel cathodic bus bars I(of carbon cathode C arrival 23 carbon pieces are shown altogether, and each carbon piece is joined two cathodic bus bars).General steel bus-bar is that stretch out the side of passing these electrolyzers, and the conductor R that makes of copper or steel is welded in the centre of each steel cathodic bus bars I in the present embodiment.Electric current is by described conductor, and the bottom of passing described electrolyzer arrives electric current current collection bus-bar B1, B2 by soft conductor F again.
In these electrolyzers, the number of the cathode block of configuration in parallel depends on the width of described carbon piece.In the large scale electrolytic cell group, carbon piece number can reach 26, but sees Fig. 1 for 23(in the present embodiment).
One of current collection bus-bar B1 is straight be configured in the long limit of cathode shell below, and, stretch out about 0.5 meter from the narrow end surface of electrolyzer.Another current collection bus-bar is configured in the opposite side of electrolyzer with the same manner.
Although in the above-described embodiments current collection bus-bar B1, B2 straight be configured in these electrolysis flute length limits below, but the present invention is not restricted to the described embodiments, and for example, Theoretical Calculation is pointed out, the current collection bus-bar can be placed on the outside a little of described cathode shell, preferably from 0.5 meter of box hat.
The one part of current that is collected among the current collection bus-bar B1 arrives electrolyzer No. 2 by two bus-bar K1 and K6, K1 and K6 be arranged at each narrow end surface outside of these electrolyzers and be in electrolyzer in the molten metal surface sustained height or be lower than the position (seeing Fig. 2, No. 2 electrolyzer) of molten metal surface.Remaining electric current arrives current collection bus-bar B2 by cell bottom following four bus-bar K2, K3, K4, K5 and arrives next electrolyzer by bus-bar S1, S2, S3, S4 and the S5 that raises again.
According to the present invention, the distribution of current from the six roots of sensation bus-bar of the conduction current of current collection bus-bar B1 depends primarily on the size of bus-bar K1 to the cross-sectional area of K6.If these electrolyzers respectively arrange wide apart each other, for example 50 meters or farther, then the cross-sectional area of bus-bar K1 and K6 should be the twice of the cross-sectional area of bus-bar K2, K3, K4 and K5.This will make two times for the electric current that passes through in the K5 at bus-bar K2 of the electric current that passes through in bus-bar K1 and K6, such distribution of current will provide very gratifying magnetic field.
Utilize mathematical model to calculate distribution of current and the magnetic field in all metal vessels of these electrolyzers in all bus-bars of arrangement of busbars, can provide the most satisfied magnetic field, and selected very correct cross-sectional area.
Utilize the method for introducing here, the maximum value of the vertical magnetic field that described arrangement of busbars forms is very low, is lower than 10 Gausses under whole anode, simultaneously, in these electrolyzers, the magnetic influence of arranging from main adjacent has obtained compensating for completely, thereby, can reduce the bus-bar number of use.
