Abstract
759,275. Electrodialytic cells. PERMUTIT CO., Ltd. Oct. 12, 1954 [Oct. 19, 1953], No. 28812/53. Class 41. An electrodialytic cell comprises an anionexchange membrane 3 and a cation-exchange membrane 4 wound about a central electrode 1 (the anode) and within an outer electrode 2 (the cathode) to form two continuous compartments 5, 6 which alternate across any radius from the central electrode 1. The membranes 3, 4 may be wound spirally or polygonally, pins extending between end caps to form guides, and the central electrode may be a rod in a former about which the diaphragms 3, 4 are wound. The membranes may be separated by insulation, e.g. by coated, integral projections thereon, or by two corrugated sheets on each side of one membrane, the corrugations running along each compartment, or by rubber or plastic bands interposed between the edges of the membranes. There may be static liquids in both compartments, or liquid may be passed continuously through one or both compartments, e.g. brine to be demineralized enters the compartment 6 at 12 and leaves at 8, and the concentration stream, which may be brine, enters the compartment 5 at 7 and leaves at 11 in a central space 13. The diaphragms 3, 4 are connected at each end to each electrode 1, 2 by insulation 16, 17, and some of the insulation 16 may be removed at the anode 1 to allow chlorine produced there to dissolve in the water in the compartment 6 which is otherwise shielded from both electrodes. Liquid flow through the cell may be concurrent.
