Definitions
- This presentation relates to a multipod and an anode assembly comprising said multipod.
- Aluminum is conventionally produced by electrolysis in electrolytic cells according to the Hall-Héroult process.
- Electrolytic cells conventionally comprise a steel box inside which is arranged a coating of refractory material, a cathode of carbonaceous material arranged at the bottom of the box, an electrolytic bath in which the alumina is dissolved, and a plurality of anode assemblies.
- An anode assembly comprises at least one anode immersed in the electrolytic bath connected to an anode rod.
- the anode rod may include a multipod structure having a plurality of bonding members or logs sealed into the anode.
- the anode assembly is traditionally suspended from an anode frame via the anode rod.
- Application WO2019123131 describes a multipod structure having a plurality of arms and logs sealed in an anode. At a given intensity, the multipod structure contributes to the thermal balance of the tank. When the current increases, the additional energy engaged must be discharged. To maintain the thermal balance of the electrolysis cells, it is therefore necessary to dissipate this excess heat resulting from the increase in the intensity of the electrolysis current. Nevertheless, the multipod structure does not increase the heat dissipation capacity of the tank.
- the anodes are more particularly of the prebaked anode type formed from prebaked carbonaceous anode blocks, that is to say baked before introduction into the electrolytic cell.
- a covering product conventionally alumina and/or electrolysis bath recovered and ground.
- the covering product generally has a fluid form which, during electrolysis operations, flows so as to permanently cover the anodes. The anodes being consumed during the electrolysis reaction, the anode assemblies are therefore regularly replaced by new anode assemblies.
- the electrolytic cells further comprise electrical conductors connecting the cathode to the anode frame of the following cell in order to conduct the electrolysis current from cell to cell.
- the electrolysis cells are connected in series and traversed by an electrolysis current whose intensity can reach several hundreds of thousands of amperes.
- one solution consists in increasing the intensity of the electrolysis current, which leads to an increase in the heat produced within the electrolysis cells. It is also necessary to maintain the thermal balance of the electrolysis cells by dissipating this excess heat resulting from the increase in the intensity of the electrolysis current.
- an anode assembly When an anode assembly is changed, coating product is poured onto the new anode in order to form a continuous cover that is as airtight as possible for the anode and to prevent the surfaces of the anode from being in direct contact with the air. Due to the high temperature prevailing in the tank near the anodes, any contact of the oxygen in the air with the carbon constituting the anode would cause oxidation of this carbon and therefore deterioration of the anode. In general, a new anode assembly is located higher than the adjacent anode assembly(s) whose anode is already partly consumed.
- the covering product poured onto the new anode of the new anode assembly also tends to pour over the adjacent anode in consumed part of the adjacent anode assembly and to pass between and/or over the logs of the multipod structure, or even possibly above the crosspiece, logs or bars and the multipod structure of the adjacent anode.
- This adjacent anode is thus covered by an excess of covering product, originating from the flow of covering product intended for the new anode, the thickness of which must in particular make it possible to protect the vertical side of the new anode from the oxidation.
- This additional covering product comes, by collapse and flow between and/or on the logs, to fill the clearance under the multipod structure and at least partially bury the logs through which some of the heat dissipation takes place. Furthermore, if the new anode is poorly covered, for example to avoid the addition of coating product on the adjacent anode, the anode mainly made up of carbon oxidizes and the logs mainly made up of iron then become accessible to the bath. electrolytic. Contact between the electrolytic bath and the logs can cause the logs to dissolve and increase the iron content in the bath and the metal.
- the present presentation aims to overcome these drawbacks by proposing a multipod and an anode assembly making it possible to reduce the effects of flow from the excess of roofing product between and/or on the logs of adjacent anode assemblies, in particular in the center of the logs, and burial of the logs and making it possible to maintain the thermal balance of the electrolytic cell, in particular by increasing the dissipation of the heat produced within the electrolytic cells, that is to say by increasing the loss or heat dissipation within the electrolytic cells.
- One embodiment relates to a multipod for the production of aluminum by electrolysis having a longitudinal axis, a transverse axis and a vertical axis, said multipod being configured to be mechanically and electrically linked to two anodes and an anode support, said multipod comprising: two parallel rows each comprising a plurality of logs configured to be connected to said anodes, at least one bar cooperating with one of said two rows mechanically and electrically, and a body connecting the two rows and being configured to be connected to the anode support.
- a single row of logs, or both rows of logs is/are provided with one or more bars. It is understood that each bar only cooperates with a single row of logs among the two rows of logs. In other words, each bar of the at least one bar cooperates with a single row of logs (e.g. with one or more logs of the same row of logs).
- Said at least one bar makes it possible to block the excess of covering product, thus limiting the flow of the excess of covering product between and/or on the logs. Furthermore, a bar cooperates with a single row so as to dissipate the heat produced within the electrolytic cells, in particular the heat produced at the level of the logs. An increase in the heat loss (or dissipation) within the electrolytic cells is then achieved. Thus, the intensity of the electrolysis current flowing through a tank equipped with this multipod can be increased, the productivity of this tank can be increased while maintaining a thermal balance.
