摘要： In an alkali salt electrolysis operation by the mercury process in which mercury recovered in a denuding tower is recirculated with wash water through a return passageway to return to an electrolysis vessel, a large portion of this mecury is thus returned to the electrolysis vessel, and the remainder portion of the mercury, together with the wash water and mecury emulsion floating and flowing above it, undergo auxiliary recirculation back to the denuding toward.

摘要： A multiple vertical diaphragm type electrolytic cell which is fitted with a plurality of gas-bubble guiding partition plates and/or in a style of up-and-down stages to the confront surfaces of electrodes and/or in every anode chamber and/or cathode chamber so as to form a perpendicular gas-bubble passageway at the vertical central plane position of said electrode chamber; wherein the gas-bubble guiding plates incline upwards toward the gas-bubble passageway. The guiding plates are constructed of heat-resistant synthetic resin and are slightly separated from the walls of the electrodes.

摘要： In an alkali salt electrolysis operation by the mercury process wherein mercury recovered in a denuding tower is recirculated with wash water through a mercury return passageway to be returned to an electrolytic cell, a portion of the mercury is caused to constantly overflow together with washing water over a weir provided in the mercury return passageway and then to undergo auxiliary circulation to a mercury reservoir interposed between the denuding tower and a mercury pump. An alkali chloride electrolytic apparatus, in which a reservoir tank is provided between a denuding tower and a mercury pump and an auxiliary circulation passageway communicates between a mercury return passageway and an entrance of the reservoir tank.

摘要： A BAFFLE PLATE WITH AN OUTLET OPENING BELOW IS LOWER EDGE FORMS A PARTIAL SIDE WALL OF PASSAGEWAY THROUGH WHICH MERCURY OR MERCURY AMALGAM FLOWS TOGETHER WITH CONTAMINANTS AND A SOLUTION FLOATING ABOVE IT IN A MERCURY PROCESS APPARATUS AND ONLY THE MERCURY OR AMALGAM IS PERMITTED TO PASS UNDER AND PAST THE BAFFLE INTO ANOTHER PASSAGEWAY PARALLEL TO THE FIRST PASSAGEWAY,
THEREBY BEING SEPARATED FROM THECONTAMINANTS AND SOLUTION, WHICH ARE BLOCKED BY THE BAFFLE. THE BAFFLE ALONG THE SIDE WALL AFFORDS THOROUGH SEPARATION WITHOUT MIXING DUE TO TURBULENCE OF CONTAMINANTS AND SOLUTION WITH SEPARATED MERCURY OR AMALGAM.-

摘要： An electrolytic cell for producing caustic soda comprising a large number of unit cells installed compactly in a cathode tank in electrically parallel connection, each of said unit cells consisting of two anode plates interwelded by at least two electroconductive supporting rods which in turn are connected to outer bus bars, an iron mesh cathode frame lined with an asbestos diaphragm surrounding the anode plates at a prescribed narrow distance, a corrosion-resistance cap mounted on the iron mesh cathode frame and a bottom dish inserted thereinto. The outer upper side walls of the anode plates are supported by setscrews to prevent the upper part of the anode plates from rocking.
