Abstract
An apparatus is disclosed for the electrolytic production of a solution of an aqueous alkali metal hypochlorite solution. The apparatus is especially useful for chlorinating swimming pools. The single vessel is partitioned horizontally into an upper compartment for the brine and a lower compartment serving as the electrolytic cell and provided with a removable electrode assembly with an electrode spacing of at least 0.5 inch. Brine feeds through and evolved gas emerges through the partition.
Claims9
An apparatus for the controlled production of an aqueous alkali metal hypochlorite solution, which comprises:
- (a) tank and means forming a vent at an upper part of said tank;
- (b) a tank cover movably mounted on the upper end of said tank;
- (c) an electrode assembly inserted into said tank and removable therefrom, said electrode assembly comprising an anode, a cathode, and a support holding the anode and the cathode at least one-half inch from one another, but in juxtaposed relation;
- (d) a D.C. power source electrically connected to said anode and to said cathode;
- (e) a partition within said tank dividing said tank into an upper compartment for containing brine and a lower compartment containing the electrode assembly, said partition defining at least one hole to controllably allow brine to pass from said upper compartment to said lower compartment and being provided with means for allowing hydrogen produced in the electrolytic cell in the lower compartment to pass through the brine in the upper compartment to then exit the tank through said vent;
- and
- (f) means communicating with said lower compartment to remove aqueous alkali metal hypochlorite solution therefrom.

An electrolysis tank which comprises:
- (a) a vessel and means forming a vent at an upper part of said vessel;
- (b) a cover movably mounted on said vessel;
- (c) an electrode assembly inserted into said tank and removable therefrom, said electrode assembly comprising an anode, a cathode, and a support holding the anode and the cathode at least one-half inch from one another, but in juxtaposed relation;
- (d) a partition within said tank dividing said tank into an upper compartment for containing a solution to be electrolyzed and a lower compartment containing the electrode assembly, said partition defining at least one hole to controllably allow said solution to pass from said upper compartment to said lower compartment and being provided with means for allowing gas produced in the lower compartment to pass through the solution in the upper compartment to then exit the tank through said vent;
- and
- (e) means communicating with said lower compartment to remove electrolysis product solution therefrom.
