    摘要: The invention describes heat exchange devices for dry-type inlet end-boxes of mercury cathode chlor-alkali electrolysis cells. The devices increase the heat exchange between recycled mercury and feed brine with the purpose of reducing the temperature of mercury to a substantial extent The devices consist of a first element directed to subdivide the mercury flow into a fine and a stable dispersion of rivulets and droplets and of a second element capable of increasing the brine level to allow the prolonged contact thereof with mercury. The decrease of mercury temperature below the critical value of 90-95 ° C. determines an advantageous duration improvement of the end-box internal lining.

    摘要: An adjustable elastic element (19) for forcing the surfaces of expandable-type anodes for diaphragm chlor-alkali cells wherein such element consists of a U-shaped elastic sheet provided with at least one adjusting mechanism comprising both one collar (29) which fastens the elastic sheet through openings obtained in the sheet itself and one gear (23) connectable to a removable external tool consisting of a handle and a shaft whereby turning the tool, a rotation of the gears is produced, in its turn acting on the collar controlling the span of the anode surfaces. And the span is freely adjustable in order to establish a predetermined controlled gap between anode and finger-supported diaphragm surfaces, or alternatively to bring such surfaces in contact without introducing however a useless and hazardous compression.

    摘要: The invention concerns a motorized device for adjusting the interelectrodic gap in mercury cathode electrolysis cells, mainly consisting of a frame, to which a number of anodes are suspended, movable in the vertical direction by means of a single jackscrew driven by a gear motor acting on double levers. The jackscrew with the motor and the lever system are fixed to a main frame, supported on the cell bottom by means of supports positioned on adjustable columns, while the above mentioned movable frame (also called sub-frame) carrying the anodes, is connected to the lever arms by means of four hinged supports. The shifting of the movable frame and, consequently, of the anodes can be controlled by a centralized and computerized system (which is not part of the invention) as a function of voltage and current variation measurements.

    摘要: The invention relates to a current collector for electrochemical diaphragm or membrane-type cells, comprising a layer obtained by interlacing or weaving of a multiplicity of first sets of metal wires with a multiplicity of single metal wires or of second sets of metal wires and provided with substantially parallel corrugations. Such layer is coupled to a planar element consisting of a cloth or a flattened stocking formed by weaving of a single metal wire. The current collector is characterised by a low angular coefficient of the pressure/thickness ratio over a wide range of compression levels.
