ABSTRACT:
An ejector type gas-liquid mixing apparatus having a valve for feeding a gas, which does not adversely affect the main gas-liquid mixing operation, into the gas feed system thereof, when the pressure of the gas feed system decreases below a predetermined value, wherein the valve is disposed between an aspirating inlet of the ejector and the gas feeder. Thus, in an apparatus for mixing a liquid and ozone using an ejector, which comprises a first pipe system for connecting the ejector and an ozone generator, a second pipe system for connecting a reaction vessel for separating the unreacted ozone from the gas-liquid mixture fluid fed from the ejector, an exhaust ozone removing device for removing the unreacted ozone, and such check valve connecting the first and second pipe systems, any ozone leaked from the check valve is removed by the exhaust ozone removing device and counterflowing liquid from the aspirating inlet of the ejector to the gas feed system is prevented.
