摘要:
THE REFINED BRINE RECIRCULATED TO A MERCURY-CATHODE CELL IS INTRODUCED INTO THE CELL IN THE FORM OF A FALLING LAMINARFLOW CURTAIN ALONG ALMOST THE ENTIRE INNER SURFACE OF AN INLET TRANSVERSE WALL OF THE CELL ABOVE THE RECOVERED MERCURY INLET, THE LAMINAR-FLOW CURTAIN OF BRINE THEREBY REACHING AND THROUGHLY WASHING THE ENTERING MERCURY TO PREVENT ANY ALKALINE WASH WATER FLOWING ABOVE THE MERCURY FROM REACHING THE GRAPHITE ANODE. THIS LAMINAR-FLOW CURTAIN IS FORMED BY A LONG AND NARROW BRINE INLET PROVIDED IN AND EXTENDING HORIZONTALLY ACROSS THE FULL WIDTH OF THE TRANSVERSE WALL AT A POSITION SUFFICIENTLY HIGH ABOVE THE SURFACE LEVEL OF THE ELECTROLYTE IN THE CELL.
