Definitions

  • the invention relates to a method for managing the operation of an igneous electrolysis aluminum production plant. It also relates to the installation implementing this method.
  • the production of aluminum by igneous electrolysis implements an electrolysis reaction of alumina in a molten cryolite bath according to the reaction:
  • This reaction uses a melt comprising a mixture of cryolite and alumina, the temperature of which is generally greater than 800 ° C.
  • the aluminum production facilities using this technology generally operate continuously in series of aluminum tanks, the number and dimensions of which are a function, on the one hand, of the available amperage of the current continuous feeding the tanks, and secondly, the amount of production desired.
  • the installations are frequently organized in such a way that they have a series of tanks in series, mounted parallel to one another, installed in the same building or in separate buildings, arranged symmetrically by relative to a central aisle intended in particular to allow the handling of molten cryolite bath bags for electrolytic cells, the lifting beams of the anode frames and other circulations of the tank accessories, and more particularly for the handling of pockets of reception of molten aluminum obtained by electrolysis.
  • each of said machines (5) is capable of carrying out all the tasks corresponding to the functions necessary for the proper functioning of the installation. More specifically, a machine (5) performs, during a first translation over a batch (11) of tanks to which it is assigned the same task determined, so that it repeats this task at the level of (n- 1) consecutive vats. Then, said machine is translated to the original tank of the batch (11) considered, in order to perform a second task, different from the previous one, and, the cycle is thus recommenced for the various tasks necessary for the operation of the installation .
  • this mode of operation induces a complexity in the technological organization of the machines, unfavorable to the automation of the functions.
  • This complexity of organization also induces the implementation of heavy and bulky machines, burdening the manufacturing costs of the machines, but also more general civil engineering related to the size of buildings and factories in which such facilities are mounted.
  • the object of the present invention is therefore to optimize the equipment, thereby increasing their productivity and as a corollary, to reduce both the operating costs and the construction costs of the facilities of the type in question.
  • This method consists in ensuring the various handling operations at each of the tanks, necessary for the operation of the installation, in a closed loop, the organs necessary for said operation being translated at the level of the whole of the tanks of the electrolysis halls. according to continuous cycles and always in the same direction.
  • said members are translated at the first hall in a specific direction to the end of said hall, then are transferred to the adjacent end of the parallel hall, called the second hall, and then translate in the opposite direction relative in the direction of translation adopted at said first hall at said second hall, and finally are transferred to said first hall, to start again the different cycles necessary for the operation of the installation.
  • each of these organs provides a smaller number of operations than in the context of prior art installations, repeated from one tank to another, and constantly traveling in the same direction to the end halls, where they are transferred to the parallel hall via a transfer bridge or ferry bridge.
  • the invention consists in ensuring a cyclisation of the displacement of the organs necessary for the operation of the installation, said installation operating in a rotating flow with respect to said members.
  • this mode of operation leads to an improvement in productivity and profitability, reducing downtime and ensuring full operation of organs or machines, and requiring less equipment in reserve to deal with any unavailability of machines during operation.
  • each type of specialized machine or body is characterized by dimensions, volumes and weights that are lower than those of the multifunctional machines of the prior art. This leads to the possibility of reducing the volumes and dimensions of buildings intended to house this type of installation, but also the dimensioning of the structural elements, resulting in a significant reduction in investment costs.
  • the members are mono-function.
  • these single-function devices operate in series or trains of several organs.
  • the members are multifunctional and advantageously are divided into two basic machines, respectively an anode handling machine, providing the tapping of the surface crust, the tearing of worn anodes, the cleaning of the cavity of the tank, the introduction of new anodes with leveling measure of the anodes, and a more general function machine handling of the ladle of aluminum casting and handling of the lifting beam of the frames of anodes at the level of the tanks, ensuring further work annexes.
  • the installation is therefore provided with a series of pairs each consisting of these two types of machine, always operating in a closed cycle.
  • the invention finally relates to the installation implementing this method.
  • the figure 1 is a schematic representation, illustrating, as already said, the mode of operation of the installations of the prior art.
  • the figure 2 is a schematic representation illustrating the operating principle of the installation according to the invention.
  • the figure 3 is a schematic representation in perspective illustrating the machine for handling and lifting anodes, of the type used in the invention.
  • the figure 4 is a diagrammatic representation in perspective illustrating the machine with multiple objectives and handling of the ladle, of the type used in the invention.
  • the figure 2 relates to the invention itself, and in particular the method of managing the operation of an aluminum production plant according to the technology of igneous electrolysis.
  • the installation of the type in question is installed in a building represented by the general reference (1) and may comprise a single building or two separate buildings. It integrates two halls, respectively (2) and (3), each comprising a series of electrolysis cells mounted parallel to each other, and symmetrically to each other with respect to a central aisle (4). ) bounded by the two halls.
  • This central aisle is used, in known manner, as an implantation zone of the alumina supply device of said tanks, and moreover, to receive the implantation of a system for capturing and treating fumes, in particular gases from the electrolysis reaction (in particular carbon monoxide and dioxide, oxygen and fluorinated emanations).
  • tanks are substantially identical to each other and include the elements necessary for their operation. They receive in particular the molten electrolysis bath consisting of alumina and fused cryolite.
  • the machines ensuring the operation of the installation work in closed loop at the two series of tanks (2) and (3).
  • five pairs of two machines (13, 14) thus operating in a closed loop. More precisely, four of these pairs (13, 14), (13 ', 14'), (13 ", 14") and (13 "', 14"') are operational, the latter represented in the maintenance zone (15). ) not being required to operate during normal operation of the installation, and being intended only to allow replacement during a malfunction or failure of one of the pairs.
  • Each of the pairs consists of two different machines, respectively an anode handling machine (13) and a machine performing the other tasks necessary for the operation of the installation, and in particular the handling of the ladle and the lifting of the anode frames .
  • This crane basically consists of a crane (15), intended to move over the series of tanks.
  • This crane comprises different raceways, respectively (16), (17) and (18), oriented perpendicular to the translation direction of the bridge (15), each of the aforementioned raceways being intended to receive a carriage carrying organs providing different functions.
  • the raceway (16) receives a carriage (19) for receiving a lifting tool, at the end of which is mounted a tapping tool of the surface crust present at the surface of each of the tanks.
  • the raceway (17) receives a carriage (20), also receiving a hoist provided at its free end with a tool for tearing the worn anodes.
  • This carriage (20) is also intended to ensure the introduction of new anodes with a corollary a measure of the leveling of the anodes.
  • raceway (18) receives a carriage (21) for receiving a hoist carrying a tool for cleaning the cavity of the vessel.
  • this machine (13) can perform several tasks and that for example, at a tank n, it is likely to perform the stitching function while at the level of the tank (n + 1) it performs, for example, the function of tearing off spent anodes, and at the level of the tank (n + 2), the cleaning function of the cavity of the tank, the machine (13 ') having preceded it at the level of this tank having already provided the previous stitching function.
  • This crane (22) comprises two parallel raceways (23) and (24), oriented perpendicular to the translation direction of the bridge (22).
  • the inner raceway (24) is intended to receive a carriage (25) for handling the ladle alumina or aluminum bath. It typically has a lifting capacity of the order of 20 to 40 tons.
  • the outer raceway (23) is intended to receive two substantially identical carriages (26) and (27) capable of passing over the carriage (25) and intended, particularly when they operate simultaneously, to provide the lifting anodic frames.
  • auxiliary work such as for example the handling of metering pingers, inter-cell slabs during the shutdown of a tank, as well as all accessories. useful for this operation, as well as those useful for restarting a tank.
  • a pipe (31) extends from said hopper (30), so as to allow feeding of the machines (14) molten alumina.
  • said machines are routed to the end of said hopper, in order to proceed with reloading alumina.
  • the machines (14) are provided with a secondary hopper (32) integrated in the beam of the bridge supporting one of the parts of the raceways (23, 24), capable of being positioned under the end of the end of the pipe (31).
  • These secondary hoppers (32) are themselves provided with a tank filling system (33) associated with hoppers (34) associated with the tanks themselves.
  • the secondary hoppers (32) have an alumina storage capacity of about 15 to 20 tonnes, depending on the capacity of the hoppers (34) of each tank, the filling period of said tanks, and the number of tanks to be served. between two fillings of the secondary hoppers (32).
  • the alumina filling operation of a tank is carried out during the casting (ie the collection liquid aluminum) which operates at the level of the neighboring tank.
  • the synchronization of these two operations is first made possible because the filling time of an alumina tank is less than the aluminum casting time.
  • the pitch between two consecutive tanks of the same hall being constant, the structure of the crane constituting the machines (14) is made such that when such a machine is positioned in the casting position at the level of a tank, the filling mouth of the adjacent vessel coincides with the alumina supply system (32) of said machine (14).
  • the machines (13) and (14), respectively (13 ', 13 “, 13"') and (14 ', 14 ", 14"') can be transferred from an electrolysis hall to the other by means of ferry bridges, schematically represented by the references (10) and (12), and positioned at both ends of the two halls.
