Die gleichmäßige Geschwindigkoitsverteilung über den gebauten Wannenquerschnitt ei'folgt durch Einbauton (c,c!) an den beiden' Stirnseiten der allen Elektrolysezellen gemeinsamen Waim^-. Diese Einbauten können gleich oder ähnlich den Einbauten sein, wie sie in der deutschen Patentschrift 1 132 "}h 1 für eine einzelne Zelle beschrieben sind.The uniform velocity distribution over the built tank cross-section is due to the built-in tone (c, c!) On the two end faces of the waim, which is common to all electrolysis cells. These internals can be the same or similar to the internals, as they are described in German patent specification 1132 "} h 1 for an individual cell.
Es kann von Vorteil sein, zwischen den einzelnen Zellen in der gemeinsamen Wanne für die Elektrolytströinung Ur.ilonkeinrichtungen (e) aus elektrisch nicht leitendem Material einzubauen, um dadurch den linearen Abstand der Einzelze11en von a auf a. zu verkürzen. It can be beneficial to move between individual cells in the common tub for the electrolyte flow Ur.ilonkeinrichtungen (e) to incorporate from electrically non-conductive material to thereby the linear distance between the individual lines from a to a. To shorten.
Je nach den Erfordernissen des elektrochemischen Verfahrens können auch Anoden oder Kathoden mit Diaphragmen (f) verwendet werden, die zweckmäßigerweise strömungögünstig ausgebildet sind.Depending on the requirements of the electrochemical process, anodes or cathodes with diaphragms (f) can also be used which are expediently designed to be aerodynamically favorable.
