  Verfahren zur Elektrolyse von Chloralkalien mittels   Horizontaldiaphrag8en.   



   Bei der Elektrolyse von Chloralkalion mittels Horitontaldiaphragmen ist es for die Stromausbeute von Wichtigkeit, dass die Bildung von Hypochlorit, welche beim Eindringen 
 EMI1.1 
   tnndcrt   wird. Dies sucht man durch eine genaue Schichtung in der Flüssigkeit zu erroiche, indem   man z. n.   auf dem Filterasbesttuch eine dicke Schicht von Bariumsulfat und Asbest ausbreitet. Dadurch wird zwar eine Bildung von Hypochlorit fast vermieden, doch bedingt dies eine bedeutende Spannungsorhöhung. 



   Gemäss der Erfindung wird eine gute Schichtung der Flüssigkeit ohne eine solche Belastungsschicht dadurch erreicht, dass der Flüssigkeitsraum über dem   Asbesttoch   in eine möglichst grosse Zahl kleiner Abteilungen unterteilt wird. Dies kann, wie in   Fig, 1   und 2 schematisch dargestellt, durch die Anordnung paralleler Querstreifen a aus chlor-und alkalibeständigem Material, wie Glas, Porzellan, Ton, Kunstmasse aus Zement und Asbest. in den Behälter B Über dem Filtertuch b erfolgen.   Diese Querwände können   in geeigneten Rillen der Behälterwände eingesetzt sein. Die   Querwände verhindern Wirbelbewegungen   in der Flüssigkeit und Infolgedessen ein Eindringen des Chlors   10   die untere Schichte überdemDiaphragma. 



   Eine noch weitergehende Unterteilung erreicht man durch in die Abteilungen ein- 
 EMI1.2 
   dieR gleichzeitig zum Festbalten   der Querwände a dienen. Andererseits kann eine Untertoilung des Flüssigkeitsraumes auch durch eine regelmässige oder unregelmässige Anordnung dieser Hohlkörper allein erzielt werden, wie dies in Fig 4 dargestellt ist.

  Process for the electrolysis of chlor-alkalis using horizontal diaphragms.



   In the electrolysis of chloralkali ions using horizontal diaphragms, it is important for the current yield that the formation of hypochlorite, which occurs when it penetrates
 EMI1.1
   tnndcrt is. One tries to achieve this through a precise stratification in the liquid, e.g. n. Spread a thick layer of barium sulfate and asbestos on the filter asbestos cloth. Although this almost prevents the formation of hypochlorite, it causes a significant increase in tension.



   According to the invention, a good stratification of the liquid without such a loading layer is achieved in that the liquid space above the asbestos hole is divided into the largest possible number of small compartments. As shown schematically in FIGS. 1 and 2, this can be achieved by arranging parallel transverse strips a made of chlorine- and alkali-resistant material, such as glass, porcelain, clay, synthetic material made of cement and asbestos. into the container B above the filter cloth b. These transverse walls can be inserted into suitable grooves in the container walls. The transverse walls prevent turbulence in the liquid and, as a result, the chlorine 10 from entering the lower layer above the diaphragm.



   An even more extensive subdivision can be achieved by entering the departments
 EMI1.2
   dieR also serve to fix the transverse walls a. On the other hand, a subdivision of the liquid space can also be achieved by a regular or irregular arrangement of these hollow bodies alone, as shown in FIG.
