Brine feed system
The present invention relates to an electrolytic cell producing oxidants that utilizes a vacuum venturi system to meter saturated brine to the water stream to produce the correct conductivity electrolyte for operation of the electrolytic cell. The present invention comprises a venture eductor configured to accept brine from a brine source and to communicate brine to the chlorine generation system, a first control device to discourage communication of brine from the venture eductor to the brine source, and a second control device to control the rate of flow of brine from the brine source to the venture eductor.
1. A chlorine generation system comprising: (a) a brine source; (b) a water source; (c) a variable flow control device accepting brine from the brine source; (d) a check valve accepting brine from the variable control valve and configured to prevent brine flow from the check valve to the variable flow control device; (e) a venturi eductor accepting water from the water source and brine from the check valve; (f) an electrolytic cell configured to accept diluted brine from the venturi eductor; (g) a sensor configured to provide a signal representative of (i) the voltage required by the electrolytic cell, or (ii) the current required by the electrolytic cell, or (iii) a combination thereof; (h) wherein the variable flow control device is configured to control flow of brine therethrough responsive to the signal.
2. The chlorine generation system of claim 1 , wherein the variable control valve controls the flow of brine responsive to the signal such that the concentration of oxidant produced in the electrolytic cell is maintained at a predetermined level.
3. The chlorine generation system of claim 1 , wherein the (g) sensor is configured to provide a signal representative of the current required by the electrolytic cell.
4. The chlorine generation system of claim 1 , wherein the variable flow control device comprises a variable control solenoid valve.
5. The chlorine generation system of claim 1 , wherein the variable flow control device comprises a motor-controlled valve.
6. The chlorine generation system of claim 1 , wherein the variable flow control device comprises an air-controlled valve.
