摘要： A filter-press type ion exchange membrane-method electrolysis cell comprising(a) an anode structure which comprises a rectangular anode frame including a top element, a bottom element and two side elements and anode plates welded to the anode frame,(b) a cathode structure which comprises a rectangular cathode frame including a top element, a bottom element and two side elements and cathode plates welded to the cathode frame, and(c) an ion exchange membrane interposed between the anode structure and the cathode structure;whereinthe two side elements of the anode frame and the two side elements of the cathode frame have a tubular structure with a rectangular cross section,the top and bottom elements of the anode frame and the top and bottom elements of the cathode frame have a .].-shaped cross section, and are secured such that their open portions face the inside of an anode compartment and a cathode compartment, respectively, andat least one end of the top element of the anode frame communicates with the top end of the side element of the anode frame and at least one end of the top element of the cathode frame communicates with the top end of the side element of the cathode frame so that the side element communicating with the top element of the anode frame, and the side element communicating with the top element of the cathode frame form conduits for withdrawing gas and solution flowing from the anode compartment and the cathode compartment, respectively,(d) a current disperser surrounding an anode lead bar welded to anode plates within the anode structure and a current disperser surrounding a cathode lead bar welded to cathode plates within the cathode structure, whereby a region not permitting passage of gas is formed between the periphery of the anode lead bar and the inside of the current disperser welded to the anode plates and between the periphery of the cathode lead bar and the inside of the current disperser welded to the cathode plates, thus serving as a passage for a downwardly moving stream of electrolytic solution, and(e) a pipe for supplying an anolyte solution disposed within the anode compartment and a pipe for supplying a catholyte solution disposed within the cathode compartment.
