Electrolyzer, insert for an electrolyzer, supply pipe for an electrolyzer and discharge pipe for an electrolyzer

Abstract

The invention relates to an electrolyzer having a plurality of cell elements and having a supply pipe and a discharge pipe for supplying and discharging an electrolyte to and away from the cell elements, wherein, at least in sections, the supply pipe and/or the discharge pipe have at least two sub-lines designed to be galvanically isolated from one another, wherein the sub-lines are designed as eccentrically disposed sub-lines.

1 . An electrolyzer having a plurality of cell elements and having a supply pipe and a discharge pipe for supplying and discharging an electrolyte to and away from the cell elements, wherein, at least in sections, the supply pipe and/or the discharge pipe have at least two sub-lines designed to be galvanically isolated from one another, wherein the sub-lines are designed as eccentric sub-lines and are configured such that a current path extension of the current paths of electrical stray currents is effected in the supply pipe and/or the discharge pipe. 
     
     
         2 . The electrolyzer according to  claim 1 , wherein at least one of the sub-lines is designed to form a comb structure. 
     
     
         3 . The electrolyzer according to  claim 2 , wherein at least one of the sub-lines has a hexagon-shaped cross-sectional area. 
     
     
         4 . The electrolyzer according to  claim 1 , wherein the sub-lines are each designed to provide an equal cross-sectional area. 
     
     
         5 . The electrolyzer according to  claim 1 , wherein the sub-lines extend in the supply pipe with a predetermined length (L) in a direction opposite to an electrolyte flow direction (E) and/or in the discharge pipe with a predetermined length (L) in the direction of the electrolyte flow direction (E). 
     
     
         6 . The electrolyzer according to  claim 5 , wherein at least one of the sub-lines is formed by a passage extending through an insert in the supply pipe and/or discharge pipe. 
     
     
         7 . The electrolyzer according to  claim 6 , wherein at least one of the sub-lines is formed by a groove extending parallel to the passage. 
     
     
         8 . The electrolyzer according to  claim 6 , wherein the insert has at least one tube section and an annular element associated with each tube section, wherein the respective annular element extends radially outwards from the respective tube section and terminates one sub-line each. 
     
     
         9 . An insert for an electrolyzer according to  claim 1 . 
     
     
         10 . A supply pipe for an electrolyzer having an insert according to  claim 9 . 
     
     
         11 . A discharge pipe for an electrolyzer having an insert according to  claim 9 .
