    An improved anode element for monopolar filter-press electrolysis cells comprises providing said anode element with an integral hollow member positioned above the upper surface of said anode element. Preferably, said hollow member is formed as an integral extension of the electrode frame, said hollow member having an outlet for withdrawing chlorine gas and being adapted to permit continuous fluid contact with said anode element, said hollow member being further adapted to provide sufficient hydrostatic pressure in said anode element for optimal liquid flow through the diaphragm over the entire operating cycle of the electrolysis cell.

    专利说明:

    The invention relates to the construction of filter press monopolar diaphragm electrolyzers, which are widely used in the electrolysis of solutions of cooking salt, to produce hydrogen, chlorine and alkali.
    A perforated box-shaped anode for filterpress monopole Q diaphragm electrolysers is known. The diaphragm separates the cathode and anode chambers and thereby prevents the mixing of gases. To ensure continuous electrolysis through the diaphragm into the cathode chamber, it is necessary to maintain a uniform flow of liquid. For this purpose, various levels of liquid in the anodic and cathodic chambers 1 are maintained in the known electrolyzer.
    However, during operation, the diaphragm changes its resistance to the solution and it is necessary to maintain an overpressure. 25
    The aim of the invention is to increase the efficiency of the electrolyzer by providing a uniform rate of electrolyte flow through the diaphragm.
    This goal is achieved by the fact that the perforated box-shaped anode for filterpress monopolar diaphragm electrolyte jets is equipped with a camera mounted on it and communicating with it.
    The presence of a chamber / mounted on the anode allows the level of the liquid in the anode chamber to be adjusted in such a way as to maintain an appropriate flow of electrolyte through the diaphragm during the entire operating time of the electrolyzer.
    The chamber can be made as one unit with the anode and serve as its continuation. The gas released at the anode is removed through the chamber through an outlet line. The height of the hollow element is selected in accordance with the resistance of the applied membrane or diaphragm. A preferred option is when the Kgmer height is 300-800 mm, for the case of asbestos diaphragms.
    The drawing shows a schematic diaphragm electrolyzer.
    In the box perforated anodes 1 pipe 2 serves the electrolyte. Through the side perforated
    the walls of the anodes 1 electrolyte flows into the cathode chambers 3. The box-shaped perforated anodes 1 are equipped with chambers 4, connected to the box-shaped anodes 1, Chambers 4 are mounted on the anodes 1. Between the anodes 1 and the cathode 5 cameras 3 a diaphragm 5 is placed. in the anodes 1 due to the chambers 4 set higher than in the cathode chambers 3.10
    When using a membrane electrolyzer, the solution is transported to the cathode chamber 3 through the holes in the membranes.
    In the electrolysis cell operating. | -5 thus, establish the same fluid levels in the anode and cathode chambers, i.e. chamber 4 does not contain liquid under conditions.
    Thus, the use of predn of anode design for filter presses electrolyzers allows
    to conduct electrolysis more efficiently due to a more uniform flow of electrolyte through the diaphragm during the electrolysis process.
