STERILIZING-WASHING DEVICE OF RUNNING WATER PART OF RUNNING WATER SYSTEM AND ATTACHED PIPING

摘要

PROBLEM TO BE SOLVED: To ensure that the adhesion of micro-organism to a heat transfer surface and the proliferation of the micro-organism are suppressed easily, to eliminate problems of environmental protection, and to sterilize and wash a running water part and attached piping on the conditions that are also economically advantageous. ;SOLUTION: Piping 3A and 3B are connected to an inlet and outlet 2B and 2A of a running water part 2 which is indirectly heat exchanged with a heat medium F passing through a heat medium passage 1 in a heat exchanger. There is provided with a communicating pipe 5 which communicates the piping 3A to 3B between the first running water cutoff valve 4A and 4B that are interposed in these pipings 3A and 3B and the inlet and outlet 2B and 2A, so that a circulation loop 6 is formed of a running water part 2, the piping 3A, 3B, and the communicating pipe 5. In the communicating pipe 5, the second running water cutoff valve 7, a gas-liquid separator 8, a drain valve 9, a circulation pump 11, and a water supply system 14 provided with a tapping valve 12 and a water supply tank 13 are interposed, and the communicating pipe 5 is equipped with an ozone generator 15 which supplies ozone gases, so as to supply the ozone gases to the clean water from the water supply tank 3 circulating in a circulation loop 6 to perform sterilization.;COPYRIGHT: (C)1998,JPO
