Abstract
The invention relates to a method for decreasing level current of an electrolytic cell. Electric diversion materials are laid on a cathode, a steel bar or between the cathode and the steel bar. The electric diversion materials can select different resistance values according to actual demands, and distribution of cathode carbon block resistance is adjusted, and so the current in an aluminum liquid can go into the cathode uniformly. The method is advantageous in that the resistance distribution can be changed effectively, the level current in an aluminum liquid can be decreased, the stability of the electrolytic cell can be raised, the current efficiency can be raised and the service life of the electrolytic cell can be prolonged.
Description
Technical field
The present invention relates to the electrolysis field, especially relate to a kind of method that reduces the electrolyzer horizontal current.
Background technology
In traditional electrolyzer, electric current enters downwards in groove through anode, by fused electrolyte and aluminium liquid, arrives cathode carbon pieces, through the charcoal piece, with being connected by negative electrode, the rod iron in level embedding cathode carbon pieces from the electrolyzer both sides out, enters next groove by negative busbar again.Under this structure, due to always can the flow through path of resistance minimum of electric current, make to approach the steel bar current outlet side 1/3rd loads most electric current, cause in the aluminium liquid layer producing a large amount of horizontal currents, aluminium liquid layer and cathode carbon pieces distribution of current inequality are higher the closer to the current output terminal current density.And in aluminium liquid, larger horizontal current can produce electromagnetic force under the effect in magnetic field, increase the unstable of electrolyzer, reduce current efficiency, increase power consumption; The inhomogeneous meeting of distribution of current in cathode carbon pieces causes the charcoal piece to be corroded, and reduces the life-span of groove.At present, along with the maximization of electrolyzer, the increase of electrolyzer width, can arrive only more aluminum liquid horizontal electric current existence and cathode current distribution inhomogeneous.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, a kind of method that reduces the electrolyzer horizontal current is provided.
For realizing above-mentioned goal of the invention, technical scheme of the present invention is as follows:
A kind of method that reduces the electrolyzer horizontal current, at negative electrode, rod iron or lay electric water conservancy diversion material between the two, described electric water conservancy diversion material can be chosen different resistances according to actual needs, adjusts the cathode carbon pieces distribution of resistance, makes electric current in aluminium liquid enter uniformly negative electrode.
Described electric water conservancy diversion material can adopt common charcoal piece, graphite charcoal piece, semi-graphite carbon piece or other to have metallic substance or the semiconductor material of conductivity.
Can adjust the distribution of resistance of charcoal piece or rod iron by the distributing position that changes electric water conservancy diversion material, make the electric current in aluminium liquid evenly enter negative electrode.
Can adjust and being connected of negative electrode or rod iron by the shape that changes electric water conservancy diversion material, make integrated connection more smooth, thereby reach the purpose of adjusting electric current, make electric current more steady.
The invention has the beneficial effects as follows: can effectively change distribution of resistance, the horizontal current in aluminium liquid is reduced, increase the stability of electrolyzer, improve current efficiency and bath life.
