STEAM-CIRCULATING-SYSTEM PIPELINE DRYING DEVICE AND PIPELINE DRYING METHOD IN STEAM-CIRCULATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/047242
Kind Code:
A1
Abstract:
Provided are a steam-circulating-system pipeline drying device and a pipeline drying method in a steam-supplying system with which it is possible to substantially completely exhaust, to outside the system, drainage that remains in a line, which extends from a steam supplying source to a water supply tank via a steam-utilizing device, after operation of the steam-circulating system is halted, and with which it is possible to dry the inside of the line. A steam-circulating-system drying device comprises: a storage tank 11 that stores normal-temperature water; a circulation pump 12 that causes water inside the storage tank 11 to circulate through circulation piping 13; an ejector 14 that uses water supplied under pressure by the circulation pump 12 as driving water; and a drainage suction pipe 16 that is provided with a switching valve 15, and that connects a drainage suction port 14b of the ejector 14 and a steam drainage pipeline 6 to each other. The steam-circulating-system drying device is connected to a steam-circulating system, and steam and drainage that remain in a pipeline inside the system are sucked by the ejector in order to dry the pipeline.
