Description

A kind of 600KA aluminium electrolysis cell anode carbon block configuration structure

Technical field: a kind of 600KA aluminium electrolysis cell anode carbon block configuration structure is mainly applied with current density at 0.73 ~ 0.85A/Cm ², the structure design and the electrolyzer that are demarcated as the aluminium cell of 600KA level are produced and technological transformation.

Background technology: existing general 600KA aluminium cell, the pole charcoal block configuration structure adopted is the group number of anode carbon block is 56 groups, the width of anode carbon block is 740 ~ 800 millimeters, the length of anode carbon block is 1700 ~ 1900 millimeters, height≤655 millimeter of anode carbon block, (are about 0.75 ~ 0.83A/Cm in aluminum cell current density ²) and after current efficiency determines, the work-ing life (anode change cycle of single block anode charcoal block) of its anode carbon block is about about 31 days, average every day change poles 1.6 pieces, change poles frequency is higher.

The work-ing life of anode carbon block on aluminium cell and anode change cycle, depend primarily on the height of anode carbon block, consume 13.5 ~ 16 millimeter (relevant with current density and current efficiency) average every day.Anode carbon block effective consumption in electrolyzer is highly about 500 millimeter, when anode height is depleted to 130 ~ 150 millimeters, anode scrap will be taken out from the aluminium cell of online production, and replace with the new anode that a tile height is≤655 millimeters.Be commonly called as pole changing.

Due to height≤655 millimeter of anode carbon block adopted in design, the anode change cycle in work-ing life of its charcoal block is shorter, causes change poles frequency higher, can produce following defect:

1, the anode scrap hair consumption produced in Aluminum Electrolysis Production process is higher.

2, change poles causes the heat leakage of aluminium cell to increase, and destroys the thermal equilibrium in aluminium cell, and cause circuit current decrease in efficiency, consumption of electric energy is too much.

3, change poles frequency is higher, not only can cause pole changing added cost, and can cause, and anode assembling and novel residual anode processing workload strengthen, and cause the explained hereafter of aluminium electrolysis enterprise to strengthen.

Summary of the invention: for overcome now general 600KA electrolysis of aluminum due to anode carbon block configuration structure lower, the above-mentioned defect produced, reduce aluminum electrolytic residual electrode charcoal block hair consumption, improve current efficiency, reduce pole changing, anode assembling, novel residual anode processing cost, increase the performance of enterprises, the invention provides a kind of 600KA aluminium electrolysis cell anode carbon block configuration structure technical scheme.

The three-dimensional structure size that anode carbon block is different, it is the core of aluminum cell structure design and process design, a kind of technological line of aluminium electrolysis cell anode carbon block configuration structure is, at the former anode carbon block conductive area of maintenance aluminium cell, length takes advantage of wide area size substantially constant, anode scrap height is substantially constant, on the substantially constant basis of current density, effectively use the dimensional height consuming part, to reach the object extending the anode carbon block cycle in work-ing life by increasing in single block anode charcoal block three-dimensional structure.

The feature of this technical scheme is: the group number of 600KA aluminium electrolysis cell anode carbon block is 56 groups, specification is adopted to be length 1700 ~ 1900 millimeters, wide is 740 ~ 800 millimeters, highly >=805 millimeters of monomer superelevation anode carbon blocks are configured, and aluminum electrolysis cell upper part horizontal smoke cover plate is to the operation height 1300 ~ 1500 millimeters of bottom slot shell.

After anode carbon block is increased, for solving insulation and the problem of oxidation of anode carbon block, its technical scheme is, in aluminium cell, seam place and sidepiece are provided with anode carbon block mulch blocking material plate.

The electrolyzer of differing capacities, the configuration of its anode carbon block should be different, on 600KA aluminium cell, adopts the superelevation anode carbon block of above-mentioned three-dimensional structure size to be optimized configuration, the anode change cycle of aluminium electrolysis cell anode carbon block can be made to extend to more than 40 days, reach 56 days.Thus reach and reduce aluminum electrolytic residual electrode charcoal block hair consumption, reduce pole changing to the thermally equilibrated interference of electrolyzer, improve current efficiency, reduce anode assembling, novel residual anode processing cost, realize increasing the economic performance of enterprises and to save energy and reduce the cost production object.

Accompanying drawing illustrates: accompanying drawings of the present invention then can state this technical scheme more clearly.
