PROBLEM TO BE SOLVED: To provide a washing device of a polymer porcelain tube and a washing method of the polymer porcelain tube capable of effectively performing washing without damaging the polymer porcelain tube.SOLUTION: Injection nozzles 141, 142, 143 and 144 forming spray curtains around a polymer porcelain tube 10 by injecting washing water at a specified water pressure are provided. In the arranged positions (injection ranges) and postures (injection directions) of the injection nozzles 141, 142, 143 and 144, the injected spray curtains 210, 220, 230 and 240 are not directly in contact with the polymer porcelain tube and are in contact with the polymer porcelain tube 10 in a process that water droplets constituting the spray curtains fall down from vertex positions. Thereby, the reliable washing of the polymer porcelain tube 10 can be realized by a simple facility without damaging the polymer porcelain tube 10.SELECTED DRAWING: Figure 1 |
