ABSTRACT:
Apparatus for producing a chlorine gas or a hypochlorite compound comprising a housing, a plurality of carbon electrodes arranged in series, with electrodes being spaced to form chambers between adjacent electrodes and one or more hollow tubes extending through the electrodes for delivering a chloride salt brine solution to the chambers. Each chamber is divided into an anode compartment and a cathode compartment by a chloride ion permeable membrane. A fluid sealing ring or rings around the outside perimeter of each electrode and around each hollow tube separates the permeable membrane from each electrode thereby dividing each chamber into an anode compartment and a cathode compartment divided by the membrane. The salt solution is applied to a hollow tube and flows through apertures therein into each anode compartment. A negative D.C. current is supplied to the electrode on one end of the series of electrodes and a positive D.C. current is supplied to the electrode on the other end to thereby induce a chlorine gas producing reaction in the chambers. When producing a hypochlorite the housing has means whereby the chlorine gas, hydrogen and alkali or alkaline earth hydroxide may be intermixed. When elemental chlorine is desired, the housing has a plurality of hollow tubes extending through the electrodes one of which opens into the anode chamber through which the chlorine is allowed to escape and the other opening into the cathode chamber through which hydrogen gas and the alkali or alkaline earth hydroxide may be withdrawn.
