    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: A structure of cathodic fingers for a chlor-alkali diaphragm cell with improved voltage and faradic efficiency is described, characterized in that a sheet provided with projections is inserted inside each finger. The interwoven wire mesh or the perforated sheet, forming each finger, is secured by a conductive connection, preferably by welding, to the top of each projection, thereby providing optimal uniformity of the electrical current distribution. The projections have a shape preferably equivalent to spherical caps, disposed in a quincuncial pattern. The internal volume of each finger is subdivided by the sheet provided with projections into two portions wherein both the free upward motion of hydrogen bubbles and the free longitudinal motion of the separated hydrogen take place towards the cell perimetrical chamber. Within the internal volume of each finger, which is only partially occupied by the projections, the natural recirculation of the solution constituted by the product caustic soda and the depleted sodium chloride also occurs, supported by the hydrogen bubbles.
