Energy dissipation belongs to technical field of aluminum electrolysis come the method for adjusting side energy balance reduction electrolytic cell energy consumption.
Background technology
Currently, the capacity usage ratio of aluminium cell, 50% or so, there are about half energy to be lost by electrolytic cell, this
A little energy are lost by upper part of the electrolytic cell and side lower part, and the lost energy in top is slightly more than side lower part under normal circumstances.Under side
In the lost energy in portion, side dissipated heat accounts for 80% or so, and in entire radiation loss, heat dissipation accounts for about 35%, it is seen that
Heat dissipation and electrolytic cell energy balance relations are great.
Heat dissipation has substantial connection with electrolytic cell operation, if stove side is relatively thin, heat dissipation will be bigger than normal；If stove is helped
It is thicker, it stretches one's legs long, then heat dissipation will be on the low side, the heat dissipation of other positions of electrolytic cell just will increase.Both are abnormal
Situation has broken the distribution of electrolytic cell energy balance, has influenced electrolytic cell operating status, it may appear that electrolytic cell burner hearth inner mold is not
Many other adverse effects, such as rule, voltage fluctuation is big, and electrolytic cell operation is unstable, and current efficiency reduces, and energy consumption increases.
Therefore, heat dissipation size is conveniently and efficiently adjusted according to electrolytic cell heat dissipation situation, regular burner hearth inner mold is protected
Hinder the steady Effec-tive Function of electrolytic cell, improve current efficiency, reduces energy consumption and have become urgent problem to be solved.
Patent CN205011850U is improved traditional aluminium cell, increases insulating layer, and fill by radiating control
It sets and control is adjusted to the heat that electrolytic cell discharges, ensure that heat can be discharged when aluminium cell is operated in high current in time,
It prevents aluminium cell from crossing thermal explosion, and can guarantee and aluminium cell is kept the temperature when aluminium cell is operated in low current, prevent aluminium
Electrolytic cell crosses cooling solidification.
Patent CN105274569A is become by the way that blast pipe, discharge pipe and air-supply regulating device is arranged according to environment temperature
Change and slot condition needs, by changing air output, the heat dissipation capacity of electrolytic cell lower part cradle pot shell high-temperature region is adjusted flexibly.
Patent CN105239105A is by increasing the corner insulation of electrolytic cell and rationally controlling the guarantor of different piece on anode
The thickness of temperature material radiates to reduce corner, increase corner currents intensity, outside the electrolyte primary crystal temperature thermoisopleth of electrolytic cell corner
It moves, plays prevention and eliminate corner and stretch one's legs, regular burner hearth reaches and realizes electrolytic cell safety and stability and efficient purpose.
Patent CN1442513A welds several cooling fins, and define cooling fin in the outer periphery of pot shell
Welding position achievees the effect that reinforce large capacity pot shell heat-sinking capability.
However in the prior art, for the energy balance regulating device of aluminium cell or only heat sinking function, or only
There is heat insulation function, although or, dismounting inconvenience, it is impossible to be used in flexible regular complicated with heat dissipation and heat insulation function
Stove helps inner mold, and cost is also relatively high, and heat preservation or heat dissipation adjustment position are relatively fixed, it has not been convenient to and it is mobile, it cannot basis
Slot condition freely adjusts heat preservation or heat dissipation position.
Invention content
For the above technical problem, the purpose of the present invention is to provide a kind of sides adjusting aluminum cell side energy balance
Method adjusts heat dissipation size according to electrolytic cell heat dissipation situation, forms ideal stove side, and regular burner hearth inner mold ensures electrolysis
The steady Effec-tive Function of slot improves current efficiency, to reduce electrolytic cell energy consumption.
To achieve the goals above, the present invention uses following technical scheme：
A method of adjusting aluminum cell side energy balance, which is characterized in that energy balance tune is installed in electrolytic cell side
Regulating device, which, which has the function of increasing, radiates and reduces heat dissipation, and according to electrolytic cell heat dissipation situation, selection uses increase
Heat dissipation or the function of reducing heat dissipation, two kinds of function free switchings as needed, quantity of the described device equipped with energy open or close
Adjustable cooling fin, equipped with the cavity that can insert thermal insulation material.
Further, which is ferrimagnet, is removably attached to electrolytic cell side.
Further, the cavity of described device is wherein attached to electrolytic cell side on one side, and the cavity is far from electrolytic cell side
Another side be provided with cooling fin.
When further, using heat sinking function, insulation material is not inserted in cavity, and open different number as needed
Cooling fin adjusts heat dissipation capacity；When using reducing heat sinking function, it is closed cooling fin, and insert different amounts of heat preservation as needed
Material adjusts heat insulation effect.
The present invention can conveniently and efficiently according to electrolytic cell heat dissipation situation adjust heat dissipation size, have heat dissipation and
Heat insulating functions, device conveniently moving can freely adjust heat dissipation or heat preservation position, whole equipment structure according to electrolytic bath condition
Simply, using flexible, cost is relatively low, and using effect is very good, and regular burner hearth inner mold is adjusted to reach, and ensures that electrolytic cell is steady
Effec-tive Function improves the purpose of current efficiency.
