Abstract

PROBLEM TO BE SOLVED: To provide an ozone water making apparatus certainly separating ozone included in ozone water. SOLUTION: Ozone impossible to dissolve is included in ozone water having ozone supplied from an ozone generator 24 dissolved to be mixed therewith in a bubble like state. Ozone in this bubble like state is finely divided by a mixer 18 to be still more enhanced in dissolving ratio. The ozone water flowing in an ozone water tank 8 through the mixer 18 flows upwardly by the weir part 17 formed on a bottom part 3 upwardly at the almost intermediate part between an inflow port 4 and an outflow port 5 and gets over the weir part 17 to flow downwardly to go toward the outflow port 5. Ozone in a bubble like state is carried to the upper part of the ozone water tank 8 by ascending flow to be separated from ozone water and stored in the vicinity of the ceiling part 6 of the ozone water tank 8. Since ozone in a bubble like state rises to the vicinity of the surface of ozone water by buoyancy, it is not drawn in the flow getting over the weir part 17 to be changed downwardly from upward flow.

Then, it flows into the ozone water tank 8 from the inflow port 4 through the mixer 18. This flow of ozone water flows upward due to the weir portion 17 formed from the bottom portion 3 approximately in the middle of the inflow port 4 and the outflow port 5. Then, after passing over the weir portion 17, the direction is changed to the downward direction toward the outlet 4. By this upward flow, ozone in a bubble state is carried to the upper part of the ozone water tank 8 and separated from the ozone water, and is accumulated near the ceiling portion 6 of the ozone water tank 8. Further, since ozone in a bubble state rises near the water surface due to buoyancy, it does not get over the weir portion 17 and be drawn into the flow changing from upward to downward. The float 10 of the float valve 9 follows the water level until the ozone water tank 8 reaches a certain water level or higher, and the opening / closing valve 11 opens the discharge port 7. Emitted from. This ozone flows through the pipe 15 to the ozone decomposing device 14,
It is reduced to oxygen and released into the atmosphere.

On the other hand, when the water level of the ozone water tank 8 rises, the float 10 rises and the on-off valve 11 closes the discharge port 7. However, the water level of the ozone water suddenly rises and ozone is discharged from the discharge port 7 together with ozone. Even if water flows out, the ozone water flows out from the drain port 13 and does not flow into the ozone decomposing device 14.
