Definitions

  • the present invention relates to the general technical field of aluminum production by electrolysis in an electrolysis cell containing a cryolite bath (hereinafter referred to as " cryolite bath ").
  • the anodes are more particularly carbon type precooked.
  • Aluminum is essentially produced by electrolysis of alumina dissolved in a cryolite bath.
  • the electrolysis cell also comprises a cryolite bath contained in the box and consisting in particular of cryolite and dissolved alumina.
  • a precooked carbon block constituting the anode of an anode assembly is immersed in the cryolite bath and consumed as the electrolysis reaction producing the aluminum progresses.
  • the tank generally comprises a cowling consisting of a series of hoods placed between the upper edges of the box and the superstructure.
  • the cowling is intended to cap the open upper part between the box and the superstructure to contain the pollutant gases inside the tank.
  • At the bottom of the electrolytic cell is formed a layer of liquid aluminum discharged periodically by suction or siphoning.
  • a disadvantage of this type of electrolysis cell concerns the risks of exhausting polluting gases to the outside. These risks of gas escape can have different origins.
  • various products used in the electrolysis reaction - such as the cover product - can accumulate on the edges of the box against which the covers are supported. This accumulation of products can prevent the correct positioning of the covers. This induces the appearance of leaks of polluting gases at the upper edge of the box and between the covers disposed on each side of the tank.
  • anode rods of the anode assemblies pass through the cowling.
  • These anode rods are associated with dynamic sealing means provided to prevent the escape of gas through the junctions between the cowling and the anode rods.
  • the dynamic sealing means can be damaged, especially when handling the anode rods to change an anode used by a new anode. The damage of the dynamic sealing means induces the appearance of leaks of polluting gases at the junctions between the cowling and the anode rods.
  • Another disadvantage of this type of electrolytic cell concerns the movement kinematics of the anode assemblies when replacing a spent anode with a new anode. Indeed, the presence of the superstructure above the opening of the box generates an obstacle to the vertical displacement of the anode assemblies. It is therefore necessary to implement a kinematics of complex displacement of the anode assemblies around this superstructure to allow their extraction from the electrolytic cell.
  • US3575827 discloses a vessel in which walls, forming with the vessel and the anode assemblies a confinement enclosure, are fixed on the anode assemblies.
  • the anodic assemblies being in perpetual movement, the walls become deformed and do not quickly assume their role.
  • An object of the present invention is to provide an electrolytic cell to overcome at least one of the aforementioned drawbacks.
  • an object of the present invention is to provide an electrolytic cell having improved sealing to polluting gases and in which the extraction of the anode assemblies is facilitated.
  • the invention proposes an electrolytic cell that can be used for the production of aluminum, comprising a box covered with an inner lining and including a bottom and side walls, the box being intended to receive a cryolite bath, characterized in that the vessel further comprises a containment enclosure including side walls extending above the side walls of the vessel, and at least one vessel element moving in translation along an axis T-T ', at least one lateral walls of the enclosure being offset towards the outside of the box with respect to one of the side walls of the box, and in that the side walls offset from the box and the chamber are mechanically connected by at least one shoulder including at least one minus a window through which the tank element and the TT axis pass
  • a side wall of the chamber is considered to be offset relative to a side wall of the box when the lower edge of the side wall of the chamber is offset horizontally with respect to the upper edge of the wall.
  • side of the box. To the outside of the box means the opposite side inside the box with respect to the side wall.
  • the shoulder advantageously extends between the lower edge of the side wall offset from the containment chamber and the upper edge of the side wall of the box.
  • the shoulder is more particularly a physical wall sealing between the offset side walls of the containment chamber and the box that connects mechanically.
  • the shoulder may further advantageously support and ensure the mechanical strength of the containment enclosure.
  • the tank comprises one (or more) shoulder (s) between the box and the enclosure.
  • Each shoulder includes one (or more) window (s) through which pass (s) an element (elements) movable (s) in translation along a translation axis TT 'through the (the) window (s), in particular perpendicular to the plane in which (said) said window (s) (s).
  • This particular arrangement ie shoulder / window assembly for the passage of a respective vessel member moving in translation along an axis TT 'passing through the window) makes it possible to limit the dimensions of the window (s) so as to avoid exhausting pollutant gases to the outside of the electrolytic cell through that (s).
  • This particular arrangement also makes it possible to arrange the moving elements of an electrolysis cell - such as lifting or drilling devices - at the periphery of the box, unlike the electrolysis cells of the prior art where the devices of lifting and / or mobile drilling devices are generally positioned to the right of an opening defined by the walls of the box. Positioning the lifting devices and / or the drilling devices at the periphery of the box allows the absence of obstacle to a vertical stroke of the anode assemblies. This facilitates the realization of a sealed containment enclosure and a replacement of the anode assemblies by the top of the electrolytic cell, without requiring the implementation of a kinematic complex displacement of the anode assemblies.
  • the containment chamber makes it possible to confine the tank gases to facilitate their capture and treatment.
  • the containment enclosure advantageously comprises a removable cowling system closing an opening formed by the upper portions of the side walls of the containment chamber so as to achieve without embarrassment a change of anode assembly from the top of the electrolytic cell. .
