FIELD: chemistry.
SUBSTANCE: in an electrolysis cell for producing chlorine, bipolar electrode elements are made from a bimetallic sheet (steel+titanium); frames of bipolar chambers are made from shaped tubes; anode and bipolar chambers are made from a bimetallic sheet which is made by welding sheets with insert bimetallic (steel+titanium) elements; the anode and the cathode chambers are equipped with built-in heat exchangers, one part of which is formed by placing shortened metallic separating strips inside the chambers and hermetic sealing of the outer surface of the chambers with a metal sheet; the second part is formed by making supporting frames of the chambers hollow, which enables to use water cooling.
EFFECT: intense process of producing chlorine, easier and higher air-tightness of the electrolysis cell.
