<p>PROBLEM TO BE SOLVED: To provide the ozonic cleaner of a water feed pipeline not polluting the atmosphere or rivers by decomposing the insoluble ozone gas and dissolved ozone gas. SOLUTION: A water feed pipeline A is cleaned with an ozone-mixed water which is discharged from the pipeline terminal and sent to an intake 31c. This cleaner is provided with a case 31 in which a passage communicating with the intake, exhaust port 31e and water discharge port is formed, a first ozone decomposing bed 32 provided in the passage on this side of the exhaust port 31e and decomposing insoluble ozone gas and a second ozone decomposing bed 33 for decomposing dissolved ozone. When the pipeline is cleaned, a faucet 5 is opened, the ozone-mixed water is introduced from the intake 31c, passed through the second ozone decomposing bed 33 to decompose the dissolved ozone and discharged from a water discharge port, the insoluble ozone gas is passed through the first ozone decomposing bed 32 and decomposed, and then the waste gas is discharged from the exhaust port 31e.</p> |
