ELECTROCHEMICAL MODULAR CELL FOR PROCESSING ELECTROLYTE SOLUTIONS

摘要

The invention relates to the production of different chemical products by the electrochemical processing of electrolyte solutions of different concentrations. A cylindrical electrochemical cell for processing solutions comprises an inner, hollow, tubular anode, an outer, cylindrical cathode, and a permeable, tubular, ceramic diaphragm that is arranged between said anode and cathode and divides the interelectrode space into anode and cathode chambers so that a working section of the cell is formed. The cell comprises units for mounting, securing and sealing the electrodes and the diaphragm, which are located at the end sections of the cell, and devices for supplying and removing the processed solutions. The cathode and anode of the cell are made of titanium tubes; furthermore, the ratio of the cross-sectional area of the cathode chamber to the total cross-sectional area of the anode chamber and the diaphragm ranges from 0.9 to 1.0, and the length of the working section of the cell is 15-25 times the outside diameter of the anode. The invention makes it possible to preserve the stability of the hydrodynamic characteristics of the electrode chambers and the electric field characteristics, intensify the electrolysis process and extend the cell functionalities.
