Ozone water is made by dissolving into water the gaseous ozone generated during the discharge of oxygen or air or the electrolysis of water.
There are several methods for ozone water production from generated ozone gas, such as porous, bubble tower, U-tube, spray tower, Venturi tube, etc. Among them, venturi-based ozone mixers are widely used, due to their excellent features such as cost, performance, installation area, power consumption, etc.
One of the important ways to increase the concentration of ozone water in the venturi ozone mixer is to increase the amount of ozone gas inhalation into the gas intake. Previous studies only considered the pressure change or velocity change inside the venturi, but not much work has been done on the inhalation volume at the intake.
Rim Chol Bom, a researcher at the Institute of Nano Science and Technology, has determined the optimum geometry of a venturi tube for ozone water production through computational fluid dynamics (CFD) simulations.
The numerical results are inlet diameter of 40mm, throat diameter of 12mm, converging angle of 27° and gas inlet diameter of 7mm, with inhalation rate of 0.100 6g/s.
