WATER RECOVERY DEVICE, WATER REUSING SYSTEM AND WATER RECOVERY METHOD

摘要

PROBLEM TO BE SOLVED: To provide a water recovery device that efficiently recovers water from an exhaust gas, and to provide a water reusing system and a water recovery method.;SOLUTION: A water recovery device 10 includes: an ion exchanging collection part 21a for collecting a water vapor-containing gas G₃ from an exhaust gas G generated from a boiler 12; a differential pressure vapor collection part 21b for collecting residual water vapor G₅ based on a water vapor partial pressure difference from a residual gas G₄ obtained by removing the water vapor-containing gas G₃ from the exhaust gas G; and a condensation part 23 for condensing at least one of the collected water vapor-containing gas G₃ and the residual water vapor G₅.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
