专利汇可以提供Bipolar diaphragmless electrolytic cells专利检索，专利查询，专利分析的服务。并且Electrode assemblies and cells for electrolytic processes, including the production of alkali metal hypochlorite, alkali metal chlorate, and other inorganic and organic chemical products, comprise a diaphragm-less electrolytic cell having at least one assembly of a plurality of planar, parallel, closely spaced foraminous dimensionally stable substantially horizontally disposed anodes and a plurality of parallel foraminous cathodes substantially horizontally disposed, the cathodes interleaved with the anodes in substantially face-to-face closely spaced parallel alignment. Organic chemical products, alkali metal hypochlorite and alkali metal chlorate are produced by placing the assembly of electrodes provided with means for supplying current to the individual anodes and current from the individual cathodes, in alkali metal halide solutions, solutions of organic electrolytes and electrolyzing the solutions while maintaining operating parameters suitable for the production of alkali metal hypochlorite and alkali metal chlorate and organic chemical products.，下面是Bipolar diaphragmless electrolytic cells专利的具体信息内容。

权利要求

1. In an electrolytic cell comprising side, end, and bottom walls defining an electrolyte chamber and having disposed in said chamber at least one electrode assembly connected to an electrical source, the improvement wherein said assembly consists essentially of a plurality of parallel, horizontally disposed, foraminous, dimensionally stable anodes and a like number of parallel, horizontally disposed, foraminous, cathodes, said anodes and cathodes being interleaved in an alternate, face-to-face, spaced apart arrangement, said assembly being substantIally enclosed on four sides.

2. The cell of claim 1 wherein a central wall is positioned intermediate the side walls of the chamber and divides the chamber into a circulation area and an electrode assembly area, a portion of the wall adjacent the bottom wall of the chamber being open to permit circulation of the solution through the entire cell chamber.

3. IN AN ELECTROLYTIC CELL COMPRISING SIDE, END, AND BOTTOM WALLS DEFINING AN ELECTROLYTE CHAMBER, SAID CHAMBER HAVING DISPOSED THEREIN A MULTIUNIT ELECTRODE ASSEMBLY, THE IMPROVEMENT WHEREIN SAID ASSEMBLY COMPRISES: A. A TERMINAL ANODE ASSEMBLY CONSISTING ESSENTIALLY OF A PLURALITY OF PARALLEL, HORIZONTALLY DISPOSED, FORAMIDIMENSIONALLY STABLE ANODES; B. A TERMINAL CATHODE ASSEMBLY CONSISTING ESSENTIALLY OF A LIKE NUMBER OF PARALLEL, HORIZONTALLY DISPOSED, FORAMINOUS, CATHODES; C. AT LEAST ONE BIPOLAR ELECTRODE ASSEMBLY INTERMEDIATE SAID TERMINAL ANODE AND TERMINAL CATHODE ASSEMBLIES, EACH BIPOLAR ASSEMBLY CONSISTING ESSENTIALLY OF A VERTICALLY DISPOSED, ELECTRICALLY INSULATING AND LIQUID IMPERVIOUS PARTITION AND A PLURALITY OF PARALLEL, HORIZONTALLY DISPOSED, FORAMINOUS, BIPOLAR ELECTRODES EXTENDING THROUGH SAID PARTITION, THE PORTION OF THE BIPOLAR ELECTRODE ADJACENT THE TERMINAL ANODE ASSEMBLY BEING CATHODES AND BEING INTERLEAVED WITH THE TERMINAL ANODES IN AN ALTERNATE, FACE-TO-FACE, SPACED APART ARRANGEMENT, THE PORTION OF THE BIPOLAR ELECTRODE ADJACENT THE TERMINAL CATHODE ASSEMBLY BEING DIMENSIONALLY STABLE ANODES AND BEING INTERLEAVED WITH THE TERMINAL CATHODES IN AN ALTERNATE, FACE-TO-FACE, SPACED APART ARRANGEMENT, ALL OTHER BIPOLAR ELECTRODE PORTIONS BEING INTERLEAVED WITH HORIZONTALLY ADJACENT BIPOLAR ELECTRODE PORTIONS IN A LIKE FASHION; D. THE ENTIRE MULTIPLE UNIT ELECTRODE ASSEMBLY BEING CONSTANTIALLY ENCLOSED ON FOUR SIDES; AND E. SAID TERMINAL ANODE AND CATHODE ASSEMBLIES BEING CONNECTED TO AN ELECTRICAL SOURCE.

4. THE CELL ACCORDING TO CLAIM 3 WHEREIN A CENTRAL WALL IS POSITIONED INTERMEDIATE THE SIDE WALLS OF THE CHAMBER AND DIVIDES THE CHAMBER INTO A CIRCULATION AREA AND AN ELECTRODE ASSEMBLY AREA, A PORTION OF THE CENTRAL WALL ADJACENT THE BOTTOM WALL OF THE CHAMBER BEING OPEN TO PERMIT CIRCULATION OF THE SOLUTION THROUGH THE ENTIRE CELL CHAMBER.
