加圧型オゾン溶解処理装置

Japanese Patent JP5331238

B1

PROBLEM TO BE SOLVED: To provide a pressure type ozone dissolution treatment apparatus which can prepare ozone water of a high dissolved ozone concentration with a simple configuration of the apparatus, produces less waste ozone and achieves a high treatment efficiency by e.g. a water purification treatment.SOLUTION: A pressure type ozone dissolution treatment apparatus comprises a closed type ozone dissolution treatment vessel 1, an ozone generator 2 and a pump 3 pressure-feeding to-be-treated water W. An ozone injection conduit 4 is connected to the suction side of the pump 3; a discharge side conduit 32 of the pump 3 is extended into the ozone dissolution treatment vessel 1; and there is provided a pressure dissolution chamber 11 separated from the surroundings in the ozone dissolution treatment vessel 1 and having a single flow port 12. A spray nozzle 5 at the tip of the discharge side conduit 32 is opened so as to face the central part of the flow port 12, and to-be-treated water W mixed with ozone by the suction force of the pump 3 is sprayed, by the spray nozzle 5, into the pressure dissolution chamber 11 from the ozone injection conduit 4 through the flow port 12. The spraying dissolves ozone in water in the pressurized pressure dissolution chamber 11, and produced ozone dissolved water flows out from the periphery of the flow port 12.
