Abstract
A chlorine generator is disclosed as including an assembly for an electrolytic cell generating the chlorine and a separate assembly for feeding the chlorine gas into a body of water. The cell assembly preferably includes two separate electrolytic solutions separated by an ion permeable membrane, such that an anode and a cathode are positioned on each side of the membrane. The gas feed assembly is in fluid communication with the cell housing by two separate conduits which accommodate the flow of gas from the cell to the feed assembly, within which the gases are accumulated and intermixed with a portion of water which has been diverted from the main body of water to flow through the feed assembly and then back to the main body of water.
Claims22
In a method of injecting chlorine into a desired stream of water, the steps of:
- (a) simultaneously, electrolytically generating chlorine gas and hydrogen gas within an electrolytic cell comprising an anode and a cathode immersed in an aqueous electrolytic solution;
- (b) collecting the chlorine and hydrogen gas in respective separate regions in the electrolytic cell above the electrolytic solution;
- (c) in response to the naturally occuring pressure developed by the generation and collection of gases in Steps (a) and (b);
- separately conveying the chlorine and hydrogen gases essentially free of electrolytic solution through two individual conduits to a gas feed system including an enclosed housing and an interior chamber into which the gases are directly conveyed by said two conduits;
- (d) flowing at least a portion of said desired stream of water into the enclosed housing of the gas feed system and into the interior chamber;
- and then
- (e) flowing the water, chlorine and hydrogen from said interior chamber to the desired stream of water.
A chlorine generation and supply assembly including an electrolytic cell having a housing enclosing an anode and cathode for the generation of gases, including chlorine, and means for accommodating the aspiration of the gases from the housing, the improvement of:
- a gas-feed system for fluid communication with the electrolytic cell and including a housing for receiving water from a body of water to be chlorinated, the housing including
- (a) an enclosed major chamber for receiving the flow of water and an enclosed minor chamber to receive both the gaseous chlorine and the flow of water, the major and minor chambers being in fluid communication such that the water supplied to the major chamber may freely flow into the minor chamber, and the minor chamber being formed as a compartment in the major chamber;
- (b) means for supplying a stream of water to the major chamber;
- (c) a control valve for regulating the flow of water from the supply means to the major chamber in order to maintain an essentially constant volume of water within the housing;
- (d) a first conduit in fluid communication with the minor chamber for supplying the gaseous chlorine thereto from the electrolytic cell, and
- (e) a second conduit in fluid communication with the minor chamber for conveying water and intermixed chlorine from the housing to the desired body of water.
