WASHING METHOD OF FORCE FEED PIPELINE

摘要

PROBLEM TO BE SOLVED: To provide a washing method of a force feed pipeline capable of recovering efficiently washing water in the force feed pipeline.;SOLUTION: In a washing method of a force feed pipeline, a stopper 12 is provided on the downstream side end part of the force feed pipeline 2, and after an elastic body 8 for cleaning moving in the force feed pipeline 2 arrives at the stopper 12 by being pushed by washing water w, a compressed fluid ar is supplied from the downstream side end part so as to push back the elastic body 8 for cleaning to the upstream side of the force feed pipeline 2, and the washing water w in the force feed pipeline 2 is pushed out into a washing water recovery part 9 arranged on the upstream side of the force feed pipeline 2, to thereby recover efficiently used washing water.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
