Definitions

  • the invention relates to the production of aluminum by igneous electrolysis. It relates more particularly to the means for confining gaseous effluents produced during electrolysis.
  • Aluminum metal is produced industrially by igneous electrolysis, namely by electrolysis of alumina in solution in a bath of molten cryolite, called electrolyte bath, according to the well-known Hall-Héroult process.
  • the electrolyte bath is contained in tanks, called “electrolysis cells", comprising a steel box, which is coated internally with refractory and / or insulating materials, and a cathode assembly located at the bottom of the tank.
  • Anodes made of carbonaceous material are partially immersed in the electrolyte bath.
  • the assembly formed by an electrolytic cell, its anodes and the electrolyte bath is called an electrolysis cell.
  • a widely used solution consists in providing the electrolysis cells with an effluent collection device.
  • This device covers the electrolysis tanks and comprises means of containment, which include in particular a rollover device, and means for suctioning and chemical treatment of the effluents.
  • the known effluent treatment processes include the recovery of fluorinated gases by reaction with alumina.
  • the cowling device comprises access means, such as covers, generally removable, and a casting door, which allow to intervene on the tank.
  • the rollover device delimits a confined suction zone and in depression with respect to the ambient atmosphere, which makes it possible to effectively recover the effluents. This results in steady-state capture efficiencies of over 97% in the most modern industrial facilities, so that the rates of atmospheric emissions of gaseous fluorinated products are well below regulatory thresholds.
  • the anodes are connected to an electrical power supply bar, located outside the collection device, via metal rods which pass through the device through openings in the device.
  • the free space (or "clearance") left by the rods in these openings is not sealed to allow vertical and horizontal movements of the metal rods.
  • Vertical displacements are frequent and allow, in particular, to compensate for the wear of anodes during electrolysis.
  • Horizontal displacements generally come from the replacement of spent anodes.
  • the free spaces between the anode rods and the inner edge of the passage openings constitute a rupture of confinement which is of small importance for each anode rod, but which becomes significant for all the anodes of a cell, and a fortiori for a series of several hundred cells.
  • the present invention relates to a leak limiter adapted to reduce the confinement breakage from the passage openings of the anode rods. More specifically, the leakage limiter according to the invention is intended to limit the air and gas passages between the inside and the outside of the capture device of an aluminum production cell by igneous electrolysis through passage openings of the anode rods.
  • the leakage limiter of an electrolysis cell according to the invention is characterized in that it comprises at least one support, able to surround all or part of an anode rod, and at least one sealing body.
  • flexible device arranged on all or part of the periphery and intended to close all or part of the free space between the inner edge of the passage openings and the anode rod.
  • the flexible body provides a certain seal around the anode rod and allows the maintenance of this seal, thanks to the flexibility of the body, despite inevitable variations in the position of the rod.
  • the invention makes it possible to substantially limit gaseous exchanges by said free space.
  • the support is advantageously in the form of notch in order to simplify the construction of the leak limiter and to allow lateral insertion of an anode rod through the opening of the notch.
  • the subject of the invention is also an electrolysis cell comprising at least one leakage limiter according to the invention.

  • the confinement means typically comprise removable hoods (14) and a fixed hood (15).
  • the sensing device comprises openings (17) able to freely pass an anode rod (3).
  • This opening usually takes the form of a slot to allow the insertion of an anode rod.
