Abstract

1,179,662. Mercury cathode electrolysis cells. ORONZIO DE NURA IMPIANTI ELETTROCHIMICI S.A.S. March 4, 1968 [March 3, 1967], No.10415/68. Heading C7B. In a flowing mercury electrolysis cell comprising a cathode base plate over which mercury can flow, anodes terminating above and adjacent the base plate, means to introduce into and withdraw electrolyte from the cell while maintaing the cell substantially filled with electrolyte, and means to introduce mercury into and discharge amalgam from the cell, and insulating mercury spreader member extends across the cell above the base-plate adjacent the mercury inlet, the member being so shaped and located that mercury introduced into the cell through the inlet is separated from the electrolyte by the member for a distance approximately equal to one sixth of the length of the base plate in a longitudinal direction. In the form shown in Fig. 1 a tier of 5 cells 1a, b, c, d and e superposed one above the other and connected to a source of current via anode bus bars 34 and cathode bus bars 35, the bases of the cells intermediate thereof forming bi-polar electrodes Mercury is supplied to the cells by means of pump 10 driven by motor 10a via conduit 11, electromagnetic flow meter 11d, a mercury feed proportionator 12 where it is separated into five equal streams each of which is passed to a mercury feed star wheel circuit breaker 12a. (Figs. 6-8, not shown) and thereafter via the inlets 14a, .. e to the cells 1a ... e. Amalgam leaves the cell via conduits 15a ... .. ... e, the streams of amalgam passing via amalgam discharge star wheel circuit to separate decomposers 16a ... e from whence the mercury recovered is recirculated. Electrolyte is supplied to the cells via inlets 4a .., e (4a only shown) and is discharged via outlets 2a .., e. Above the mercury inlet of each cell is positioned the mercury spreader member 23 (see Fig.13), and the electrolyte inlets 4a being positioned above this member (not shown in Fig. 13). The anodes may comprise perforated platinum plated titanium sheets connected by conductor rods to the under surface of the cathode base plate of the tier above. (Fig. 4 not shown).
