Title:
オゾン混合装置及びオゾン混合方法
Document Type and Number:
Japanese Patent JP4206676
Kind Code:
B2
Abstract:
An ozone mixing device and an ozone mixing method are provided, wherein ozone gas of predetermined concentration can be dissolved in water with less pressure loss even if liquid-gas ratio is increased and gas pressure is reduced. An ozone mixing device (1) comprises a chamber (3) having an inflow port (2) for pressurized water, a diffuser (4) communicating with the chamber (3), and an ozone gas feed pipe (5) inserted in the chamber (3) and opening to the inlet port of the diffuser (4), the front end of the ozone gas feed pipe (5) forming a throttle member for throttling the flow channel leading to the inlet port of the diffuser (4). Ultrapure water having a gauge pressure of about 0.1 - about 0.3 MPa is allowed to flow into inflow port (2), while ozone gas having a gauge pressure of about 0.05 - about 0.2 MPa is fed into the ozone gas feed pipe (5).
