ABSTRACT:
An open-cell electrolyte chlorine generator such as a type used for the chlorination of various aqueous streams including swimming pools is constructed without the use of a diaphragm or membrane isolating or partitioning the electrolyte between the anode and cathode. Instead, a gas separating plate separates the electrolyte above horizontally projecting electrodes, in order to keep the different gasses generated at the different electrodes separated as they rise to the top of the cell. Aqueous buffering reagents are added to the chloride-containing electrolyte to neutralize the hydroxide anions generated at the cathode and to optimize the evolution of chlorine gas by stabilizing the pH of the electrolyte. The chlorine and hydrogen gasses produced may be separately added to the solution which is to be treated, with an optional cooling circuit taking the pre-treated solution and passing it through the cell (in heat-exchanging tubing) prior to treatment with the gasses. Thus during much of the operation of the cell, only the desired product (chlorine gas) and the easily disposed of hydrogen gas must be removed from the cell.
