| 摘要 |
The invention relates to an electrolysis cell for preparing liquid alkali metal from a liquid alkali metal-heavy metal alloy, which comprises a tube ( 1 ) which is arranged essentially horizontally and has a closure device ( 4 ) at each of the two ends of the tube ( 1 ), at least one solid electrolyte tube ( 12 ) arranged in the tube ( 1 ), which conducts alkali metal ions and is closed at one end and has an opening ( 11 ) at the other end, with the solid electrolyte tube ( 12 ) being arranged concentrically in the tube ( 1 ) and having the opening ( 11 ) facing one end of the tube ( 1 ) so that a first annular gap ( 13 ) for conducting the liquid alkali metal-heavy metal alloy which forms one anode is present between the inside of the tube ( 1 ) and the outside of the solid electrolyte tube ( 12 ), an interior space ( 14 ) in the solid electrolyte tube ( 12 ) for accommodating the liquid alkali metal which can be utilized as cathode, where the closure device ( 4 ) comprises an alkali metal-heavy metal alloy inlet ( 8 ) or outlet ( 9 ) opening into the first annular gap ( 13 ), a holder for the solid electrolyte tube ( 12 ), an alkali metal outlet ( 15 ) connected to the interior space ( 14 ) of the solid electrolyte tube ( 12 ) and a sealing system for sealing the interior space ( 14 ) of the solid electrolyte tube ( 12 ) and the alkali metal outlet ( 15 ) off from the first annular gap ( 13 ), the alkali metal-heavy metal alloy inlet ( 8 ) or outlet ( 9 ) and from the surroundings of the electrolysis cell.
