Abstract
The invention discloses a partition multichamber aluminum electrolysis cell which comprises an anode (1) and a cathode (2), wherein the cathode (2) is provided with a diversion trench (3); a plurality of partitions (4) are arranged among the anode (1); and the partitions (4) are embedded or arranged on the upper surface of the aluminum electrolysis cell cathode (2) to form the multichamber aluminum electrolysis cell. The partitions (4) adopt an embedded slab structure or flatwise staircase structure. The height of the partitions (4) is slightly greater than that of the molten aluminum layer. The intervals between every two partitions (4) are equal or unequal. By adopting the unique partition technology, the invention can effectively reduce the horizontal current, prevent or reduce the radial flow rate of the molten aluminum layer, reduce the interfacial oscillation and secondary reaction of the molten aluminum, and enhance the stability and current efficiency of the aluminum electrolysis cell, thereby implementing energy saving and consumption reduction.
Description
Technical field
The present invention relates to a kind of partition-board multi-chamber aluminum electrolytic cell, belong to the aluminium cell technical field.
Background technology
During existing aluminium cell electrolysis production, the aluminium liquid of separating out is accumulated in charcoal piece negative electrode top, forms the aluminium liquid layer of certain altitude, and as the part of negative electrode.The impact that is subject to electromagnetic field owing to the aluminium liquid layer of certain altitude on the charcoal piece negative electrode moves overruns, and causes aluminium liquid secondary reaction probability to increase, and greatly reduces the current efficiency of aluminium cell.Along with the development of aluminum electrolyzation technology, improve and industry policy, energy-conservation, consumption reduction on requirement, electrolyzer is gradually to large scale development, theoretical and the production practice both domestic and external according to electrolysis of aluminum, the aluminium cell grooved is larger, its phenomenon that bias current occurs is more serious, aluminium liquid layer radially flow velocity is larger, make the stability of electrolyzer poorer, directly have influence on normal production operation and the management of aluminium cell, cause the interior aluminium liquid interfacial layer fluctuation of groove excessive, increase secondary reaction reaction probability, reduce current efficiency.
Therefore, stop and slow down radially flow velocity of aluminium liquid layer, reduce trough inner water ordinary telegram stream, stability that can the Effective Raise aluminium cell reduces the fluctuation at aluminium liquid interface, improves current efficiency, realizes energy-saving and cost-reducing.
Summary of the invention
Technical problem to be solved by this invention is: a kind of partition-board multi-chamber aluminum electrolytic cell is provided, this electrolyzer can effectively stop and slows down radially flow velocity of aluminium liquid layer, reduce trough inner water ordinary telegram stream, increase the stability at aluminium liquid interface, reduce aluminium liquid secondary reaction, cause in the groove fluctuation of aluminium liquid interfacial layer excessive with what overcome that prior art exists, increase secondary reaction reaction probability, reduce the deficiencies such as current efficiency.
The technical solution adopted in the present invention is: a kind of partition-board multi-chamber aluminum electrolytic cell, and its anode, negative electrode are processed with curb on the negative electrode, several dividing plates are set between anode, and dividing plate is inlayed or is positioned over the aluminium electrolytic cell cathode upper surface, forms multi-chamber aluminum electrolytic cell.
Be processed with curb on the electric tank cathode charcoal piece, the aluminium liquid that electrolytic reaction produces can flow into the Aluminum storage pond through curb.
Dividing plate adopts inserted slab construction or flatwise halfpace structure.
Described dividing plate height is a little more than the aluminium liquid layer.
The spacing of dividing plate adopts equidistantly or is not equidistant.
Beneficial effect of the present invention: this aluminium cell adopts to be inlayed or the halfpace diaphragm structure, can effectively stop and slow down radially flow velocity of aluminium liquid layer, reduce trough inner water ordinary telegram stream, reduce aluminium liquid interface fluctuation, improve the stability of electrolyzer, reduce the secondary reaction of aluminium liquid, the current efficiency of Effective Raise aluminium cell realizes energy-saving and cost-reducing.
