Abstract
An ozone generator which operates at constant pressures to produce a continuous flow of ozone in an oxygen stream having from 10% to 18% by weight of ozone. The ozone generator includes one or more electrolytic cells comprising an anode/anode flow field, a cathode/cathode flow field, and a proton exchange medium for maintaining the separation of ozone and oxygen from hydrogen. The ozone generator also has an anode reservoir which vents oxygen and ozone and a cathode reservoir which vents hydrogen. The anode reservoir can be filled from the cathode reservoir while continuing to produce ozone. The ozone generator is readily configured for self-control using a system controller programmed to operate the anode reservoir at a constant pressure.
Claims14
A process for generating ozone, comprising the steps of:
- electrolyzing water in one or more electrolytic cells comprising an anode, a cathode, and an ion exchange membrane disposed between the anode and the cathode;
- forming oxygen and ozone at the anode;
- recirculating water between the anode and an anode reservoir, wherein the anode reservoir comprises a first hydrophobic gas permeable membrane positioned in the anode reservoir;
- separating ozone and oxygen from water in the anode reservoir;
- discharging oxygen and ozone from the anode reservoir, wherein the oxygen and the ozone pass through the first hydrophobic gas permeable membrane;
- forming hydrogen at the cathode;
- receiving water and hydrogen into a cathode reservoir from the cathode, wherein the cathode reservoir comprises a second hydrophobic gas permeable membrane positioned in the cathode resevoir;
- separating hydrogen from water in the cathode reservoir;
- and
- discharging hydrogen from the cathode reservoir, wherein the hydrogen passes through the second hydrophobic gas permeable membrane;
- and
- receiving water into the anode reservoir from the cathode reservoir.
