Abstract
The utility model discloses an electricity outlet structure of an electrolysis bath. The electricity outlet structure comprises a cathode carbon block (1), a cathode steel rod (2), a steel rod paste (3) and an electricity outlet steel rod (4), wherein the electricity outlet steel rod (4) is arranged at the bottom of the electrolysis bath and the direction is vertically downward. At the bottom of the cathode carbon block (1), the cathode steel rod (2) which is transversely placed is connected with the electricity outlet steel rod (4) which is vertically placed. The electricity outlet structure can not only reduce the voltage of a cathode of the electrolysis bath, but also greatly reduce the horizontal current of the electrolysis bath and have very obvious effects for enhancing the stability of the electrolysis bath and reducing the direct current power consumption of the electrolysis bath, so that the electricity outlet structure has relatively high practical value and is worthy of popularization.
Description
Technical field
The utility model relates to a kind of electrolyzer and goes out electric structure, belongs to technical field of aluminum electrolysis.
Background technology
The stability of aluminium cell and horizontal current and vertical magnetic field have confidential relation, reduce stability and current efficiency that horizontal current can obviously improve electrolyzer to greatest extent, cut down the consumption of energy.Particularly under electrolyzer maximizes the megatrend of strengthening with electric current, the electrolyzer Study on Stability has become one of problem more and more important in design and the production of electrolyzer.
In theory; The instability of electrolyzer is to cause that by the electromagnetic force that horizontal current in the aluminium liquid and vertical magnetic field effect produce promptly the form of
component of three directions of being write as then becomes:
(1)
When
then above-mentioned formula becomes:
In the formula:
is electromagnetic force;
is current density, and
is magneticstrength;
;
;
refers to the long axis direction of electrolyzer respectively; Short-axis direction and vertical direction.
Can find out from top formula; When electrolyzer horizontal current value
when being 0, electromagnetic force
will not receive the influence in the magnetic field
of vertical direction.As long as therefore can control the horizontal current of aluminium liquid layer short-axis direction very for a short time, even magnetic environment is a bit weaker, electrolyzer still can be produced more stablely, that is to say that electrolyzer will be diminished by the influence of vertical magnetic field.
Because long axis direction horizontal current
is very little in the electrolyzer aluminium liquid layer; Basically can not consider; That therefore pay close attention to is
; Be the horizontal current of aluminium liquid layer short-axis direction, the said horizontal current of hereinafter all refers to
.
In the conventional cathode structure aluminum electrolysis bath, the 420kA electrolyzer that designs with Guiyang Institute of Al-Mg-Design is an example, does not do at the electric tank cathode device under the situation of any optimization, and cathode drop is at 292mV, and the horizontal current peak is at 5000A/m
2About, MV is at 2721A/m
2, as shown in Figure 1.
Horizontal current and cathode drop are a pair of contradiction; Reducing of a common side can be with the opposing party's the cost that increases to; Both reduce cathode drop in order to reach; Reduce the purpose of horizontal current again, the contradiction between unified electric tank cathode pressure drop and the horizontal current, the present invention has designed a kind of bottom and has gone out electric cathode construction.
The utility model content
The technical problem that the present invention will solve is, provides a kind of new electrolyzer to go out electric structure, deficiencies such as the horizontal current that prior art exists is big to overcome, electrolyzer operation stability difference.
In order to solve described technical problem, the present invention takes following technical scheme:
It comprises cathode carbon pieces, cathode steel bar, rod iron paste, goes out electric rod iron, goes out electric rod iron and is arranged on bottom of electrolytic tank, is directed downwards.
In the cathode carbon pieces bottom, the cathode steel bar of laterally placing is connected with the electric rod iron that goes out of vertical placement.
Cathode steel bar current output terminal satisfies
wherein L be the length of cathode steel bar 2; L1 goes out the width centreline of electric rod iron 4 to the distance between the length medullary ray of cathode steel bar 2; H is the height of cathode steel bar 2, and W is the width that electric rod iron 4.
The present invention has adopted bottom of electrolytic tank to go out electric cathode construction, goes out electricity from the electrolyzer both sides and changes into from bottom of electrolytic tank and go out electricity traditional, reaches the purpose that not only reduces cathode drop but also reduce the electrolyzer horizontal current.
Range of application: the present invention can reduce electric tank cathode voltage; Simultaneously can reduce the electrolyzer horizontal current significantly again; For stability that strengthens electrolyzer and the direct current consumption that reduces electrolyzer very significantly effect is arranged, therefore have higher utility, be worthy to be popularized.

Embodiment
Embodiment of the present invention:
Like Fig. 2,3, shown in 4, it comprises cathode carbon pieces 1, cathode steel bar 2, rod iron paste 3, goes out electric rod iron 4, goes out electric rod iron 4 and is arranged on bottom of electrolytic tank, is directed downwards.
In the cathode carbon pieces bottom; The cathode steel bar of laterally placing 2 is connected with the electric rod iron 4 that goes out of vertical placement; In
formula; L is the length of cathode steel bar 2; L1 goes out the width centreline of electric rod iron 4 to the distance between the length medullary ray of cathode steel bar 2, and H is the height of cathode steel bar 2, and W is the width that electric rod iron 4.
The present invention has changed the traditional cathode construction that goes out electricity from sidepiece of electrolyzer into go out electricity from bottom of electrolytic tank cathode construction, and this mode has shortened the flow through path of electrolyzer of electric current, therefore can reach the purpose that reduces negative electrode.Simultaneously, owing to adopted the end to go out electricity, so it can suppress electric current well and in electrolyzer, outbound flow, and can reduce horizontal current significantly.From calculation result, to adopt after this structure, the electric tank cathode pressure drop has been reduced to 235mV by original 292mV, and the horizontal current of aluminium liquid layer has also obtained remarkable reduction simultaneously, and its MV is by 2721 original A/m
2Be reduced to 423A/m
2(as shown in Figure 5).
