PROBLEM TO BE SOLVED: To provide a water recovery device attaining effective utilization of water resource by recovering water from exhausts gas containing water vapor.SOLUTION: The water recovery device comprises: an exhaust gas pipe 200 which is connected to a combustion device 2000 combusting fuel and discharging exhaust gas containing water vapor and forms an exhaust passage for exhaust gas; a water generating part 100 for generating water by cooling exhaust gas to condensate water vapor contained in the exhaust gas; and a water storing part 300 arranged on an exhaust gas passage and storing water generated by the water generating part 100. The water generating part 100 comprises: a sound wave generating part 100A for generating sound wave by absorbing heat from the exhaust gas pipe 200, applying the heat to working fluid to vibrate it; a propagation pipe 100C of which inner part is filled with the working fluid and which propagates sound wave through vibration of the working fluid; and a cold heat generating part 100B which generates cold heat by receiving the propagated sound wave and transferring heat to the sound wave, and which supplies the cold heat to the exhaust gas pipe 200.SELECTED DRAWING: Figure 1 |
