Apparatus for the production of chlorine in chlor-alkali diaphragm cells

Abstract

Abstract THIS INVENTION PROVIDES A NEW AND NOVEL ARRANGEMENT AND DEVICES FOR A CHLOR-ALKALI BATTERY WHEREIN THE CELLS ARE MADE FROM PRESTRESSED AND POLYMER INPREGNATED CONCRETE FOR BETTER RESISTANCE TO CHLORINE CORROSION, AND THE CELLS ARE DIVIDED INTO CATHODE AND ANODE SECTIONS WITH EXTERNAL ELECTRICAL CONTACT STRIPS FOR ELECTRICAL CONTINUITY AND ARRANGED SO THAT THE CATHODE SECTIONS MAY BE VERTICALLY REMOVED FROM THE BATTERY LINE FOR REPLACEMENT OR REPAIR OF THE CATHODE SCREEN OF DIAPHRAGM WITHOUT OTHERWISE DISTURBING THE ANODE UNITS. THE CELLS, WITHIN EACH BATTERY LINE, ARE HELD TOGETHER BETWEEN END MEMBERS BY USING CORROSION PROTECTED STEEL CABLES THAT ARE STRESSED AND ANCHORED THROUGH EACH END MEMBER. IN ADDITION THE CHLOR-ALKALI BATTERY LINES MAY BE ARRANGED BETWEEN CANALS SO THAT A STRADDLE-BARGE DEVICE MAY BE UTILIZED TO PLACE THE CELLS INTO THE BATTERY LINE AND INDIVIDUAL CELL UNITS MAY BE THUS VERTICALLY REMOVED AND REPLACED WITHOUT OTHERWISE DISTURBING ADJACENT CELLS IN THE CHLOR-ALKALI BATTERY LINE. A CELL WASHING AND TREATING DEVICE, INCLUDING A SERIES OF INTERNAL SPRAY JETS, IS INCORPORATED INTO EACH CELL FOR TREATMENT TO RESTORE PERMEABILITY OF THE DIAPHRAGMS WITHOUT CELL DISASSEMBLY.
