Abstract: An electrolytic pool chlorinator produces chlorinated pool water that is added to the cathode chamber to continuously dilute the caustic concentration of the catholyte before being returned to the pool. The cathode chamber includes a series of baffle plates between the primary cathode and the chlorinated pool water entry port in order to maintain the hydroxyl ion concentration near the primary cathode high enough to provide good current efficiency, yet low enough to avoid significant back-migration of hydroxyl ions. The baffle plates also cause metal hardness ions such as calcium to precipitate before reaching the primary cathode. A negatively-charged second cathode spaced apart from the primary cathode also helps to prevent precipitation of metal hardness ions upon the primary cathode.

Abstract: An electrolytic pool chlorinator for chlorinating a swimming pool includes a water distribution chamber which automatically distributes fresh pool water to a brine tank, to a cathode chamber, and to a packed column in which liberated chlorine gas is intermixed with pool water before being returned to the pool. The water distribution chamber includes a first compartment for continuously receiving pool water and having a hole therein for distributing water to the brine tank. A second compartment contiguous with the first compartment of the water distribution chamber receives pool water which spills over from the first compartment. A conduit conveys water from the second compartment to the cathode chamber for continuously diluting the concentration of sodium hydroxide therein. The conduit delivers pool water to the cathode chamber at a controlled rate and at a point relatively remote from the cathode to prevent calcium deposit formations upon the cathode.

Abstract: An electrolytic pool chlorinator for chlorinating a swimming pool or the like generates chlorine gas by electrolyzing a sodium chloride solution. A baffle within an anode chamber of the chlorinator isolates undissolved salt from an anode element while collecting chlorine gas liberated at the anode element. A level indicator slidingly extends downwardly into the anode chamber to indicate the level of undissolved salt therein. Chlorine gas collected by the baffle is intermixed with water in a packed column and discharged into a feeder tank. The feeder tank includes a float valve for regulating the flow of water into the packed column and out of the feeder tank.
