Document Type and Number:
WIPO Patent Application WO/2013/191072
Kind Code:
A1
Abstract:
The present invention comprises: an ozone generator, an ozone-containing liquid generation mechanism (20), a gas introduction channel, a liquid introduction channel, a gas-liquid separator, an ozone-containing liquid delivery channel, and a gas recirculation channel. The ozone-containing liquid generation mechanism (20) includes a liquid tube, an ozone supply tube, and a non-return valve mechanism incorporated into the ozone supply tube. The ozone supply tube has a large-diameter part (25) in the upper part thereof, and has a small-diameter part (24) that is connected to the large-diameter part (25) in a location below the large-diameter part (25) and that has a smaller diameter than the large-diameter part (25). The non-return valve mechanism includes: an annular body (28) that is positioned at the upper end of the large-diameter part (25) of the ozone supply tube and that has an inside diameter which is smaller than the large-diameter part (25); a spherical body (27) that has a diameter less than the inside diameter of the large-diameter part (25) and greater than the inside diameter of the small-diameter part (24) and the annular body (28), that has a specific weight less than the liquid, and that is positioned inside the large-diameter part (25); and a circulation structure disposed inside the large-diameter part (25) and used for preventing the spherical body (27) from blocking the small-diameter part (24).
