Liquid treating electrolytic cell
First Claim
1. An electrolytic cell for producing a halogen biocide in a liquid containing a halogen salt as the liquid is passed therethrough, said electrolytic cell comprising:
- (a) a cell body defining an open ended chamber which forms a flow path for the liquid;
(b) a pair of end closure means each mounted on a different one of the open ends of said cell body;
(c) port means on at least one of said pair of end closure means for passage of the liquid through said electrolytic cell;
(d) a plurality of electrode plates each having an opposed pair of side edges and an opposed pair of end edges, said plurality of electrode plates being mounted in spaced apart parallel relationship in said cell body and coextensive with the flow path thereof;
(e) conductor means for connection of less than all of said plurality of electrode plates to a power supply;
(f) means for encasing the side edges of all of said plurality of electrode plates and the end edges of at least the ones of said plurality of electrode plates which are connectable to the power supply, said means for encasing including,I. said cell body having an opposed pair of end walls with a plurality of spacedly arranged parallel slots formed on the inwardly facing surfaces thereof for encasing the side edges of each of said plurality of electrode plates,II. each of said pair of end closure means including a cap plate for encasing the opposed end edges of the ones of said plurality of electrodes which are connectable to the power supply.

Abstract
An electrolytic cell for producing a halogen biocide and oxygen in a liquid containing a halogen salt as the liquid is passed therethrough. The electrolytic cell contains a plurality of electrode plates which are mounted in spaced apart parallel relationship in the cell with less than all of the electrtode plates being connectable to a suitable power supply. The cell is configured so that the end edges of at least the electrode plates which are connectable to the power supply are encased in an electrically insulative chemically resistant material to prevent current leakage between those plates.

5. An electrolytic cell for producing a halogen biocide in a liquid containing a halogen salt as the liquid is passed therethrough, said electrolytic cell comprising:
-
(a) a cell body defining an open ended chamber which forms a flow path for the liquid; (b) a pair of end closure means each mounted on a different one of the open ends of said cell body, a first one of said pair of end closure means having a closed end wall and defining a chamber; (c) a port means formed in the other one of said pair of end closure means for passage of the liquid through said electrolytic cell; (d) a plurality of electrode plates each having an opposed pair of side edges and an opposed pair of end edges, said plurality of electrode plates being mounted in spaced apart parallel relationship in said cell body and coextensive with the flow path thereof; (e) conductor means for connection of less than all of said plurality of electrode plates to a power supply; (f) means for encasing the side and end edges of at least the ones of said plurality of electrode plates which are connectable to the power supply; and (g) plate means for dividing said port means into a liquid inlet portion and a liquid outlet portion and for directing the flow of the liquid received from the inlet portion of said port means past some of said plurality of electrode plates into the chamber of said first one of said pair of end closure means and past the rest of said plurality of electrode plates to the outlet portion of said port means. - View Dependent Claims (6, 7, 8)
