Abstract
An electrolytic ozone generator is described, which comprises a feed tank in which water is stored, an ion-exchange column connected to the feed tank, a pump for feeding the stored water in the feed tank to the ion-exchange column, an electrolytic cell connected to the ion-exchange column and containing a solid electrolyte which is an ion-exchange membrane, an anode disposed tightly on one side of the solid electrolyte, and a cathode disposed tightly on the other side of the solid electrolyte, an electromagnetic valve connected to and disposed between the ion-exchange column and the electrolytic cell, and a hydrogen-separating column connected to the electrolytic cell and for separating hydrogen from a gas-liquid mixture sent from the electrolytic cell and circulating the resulting water to the feed tank, and in which the liquid level of the anolyte in the electrolytic cell is sensed, and, in a case wherein said liquid level is below a predetermined value, ion-exchanged water is fed from the ion-exchange column to the electrolytic cell by controlling the electromagnetic valve.
