Description
Technical field
The present invention relates to technical field of aluminum electrolysis.
Background technology
At present, the flat cathode production process of the common employing of domestic aluminum electrolysis industry large-scale pre-baked aluminum electrolysis cell.Because the density of electrolyte melt and aluminium liquid there are differences, and electrolyte melt and aluminium liquid layer distributed are on cathode surface, and aluminium liquid is above the negative electrode top layer, electrolyte melt is above the aluminium liquid layer in electrolyzer.
During the electrolyzer ordinary production, electric current in the electrolyzer can produce powerful magnetic field, Interaction Law of Electric Current in magnetic field and electrolyte melt and the aluminium liquid produces powerful electromagnetic force, electrolyte melt and aluminium liquid are circulated, thereby the interface that makes electrolyte melt and aluminium liquid produces fluctuation and protuberance distortion, can make metallic aluminium that electrolysis comes out again by the anodic gas oxidation, cause the loss of aluminium, reduce the efficient of electric current.In addition, aluminium liquid circulates and fluctuates also and brought difficulty for the stable operation of producing.
Now, along with continuing to increase of aluminium cell capacity, distributing rationally of bus makes the interface of electrolyte melt and aluminium liquid produce fluctuation and protuberance distortion, and very big improvement has been arranged.But its flow state in electrolyzer can't be controlled effectively all the time.In the aluminium cell normal productive process, influenced by single anode turbulent simultaneously, can only rely on the operating voltage that improves electrolyzer to eliminate the fluctuation of electrolyzer, so more aggravated the increase of power consumption, cause the reduction of current efficiency.
Traditional flat aluminium cell is subjected to the influence of electromagnetic force, the interface wave of electrolyte melt and aluminium liquid props up and to swell distortion bigger in the electrolyzer, so can't keep stable operation down in lower pole span (promptly low groove operating voltage), otherwise will cause declining to a great extent of current efficiency.
Existing common prebaked cell often needs the pole span that keeps bigger because the aluminium fluid wave that cause in magnetic field is moving for the stably manufactured that guarantees electrolyzer.Electric energy efficiency is hanged down and has been caused the meaningless consumption of huge electric energy on the industrial cell, and the energy-saving and cost-reducing means of aluminium cell have two kinds, and a kind of is to improve current efficiency, and another kind is exactly to reduce pole span, reduces bath voltage.And existing electrolyzer, mostly between 90 one 95%, the space of improving current efficiency is limited for current efficiency.Aluminum current electrolyzer pole span is generally about 4.5 1 6cm, the pressure drop that pole span brings is about 40% of total energy consumption, the energy-saving and cost-reducing very big space that provides is provided in the reduction of pole span, but because the restriction of traditional this body structure of electrolyzer, reduce pole span, because the aluminium liquid electrolyte interface influence of fluctuations that brought by magnetic field, it is unstable that electrolyzer will become, lose current efficiency, be difficult to reach purpose of energy saving.
Therefore, want to realize low-work voltage, the high current efficiency of electrolyzer production, must solve and improve electrolyte melt and the moving state of aluminium liquid recycle stream, reduce fluctuation of electrolyte melt and aluminium liquid interface and protuberance distortion problem, and single anode disturbance causes the defective of whole electrolyzer fluctuation to the current efficiency influence.
Summary of the invention
Purpose of the present invention: a kind of novel control fluid is provided, and its density is greater than aluminium liquid, and the electrolyte-resistant corrosion is placed above-mentioned control fluid at aluminum electrolytic cell bottom (on the cathode carbon pieces), and huge aluminium liquid pool is divided into several little zones.The present invention adopts the method to the control of aluminium cell subregion, has reduced the fluctuation of having flowed, reduced aluminium liquid of aluminium liquid in the aluminium cell, reduces the interpolar pressure drop,, reduce the influence of magnetic field to Aluminium Electrolysis stability, realized the method for electrolyzing aluminum of energy-conservation production.Improve the electric energy efficiency of aluminium cell, reached purpose of energy saving.It can be transformed on the basis of the aluminium cell of known ordinary production.
