An exhaust gas treatment device, a ship, and a water supply method, provided with: an exhaust gas recirculation line (G4) in which a portion of the exhaust gas exhausted from a marine diesel engine (11) is compressed by a supercharger (21) and recirculated as combustion air to the marine diesel engine (11); a scrubber (42) that removes organic substances by injecting water into the exhaust gas flowing in the exhaust gas recirculation line (G4); an air cooler (52) that, after organic substance have been removed by the scrubber (42), cools a mixed combustion gas that has been formed by mixing air and the recirculated gas and has been compressed by a compressor (22); and a drain water supply line (W4) that supplies to the scrubber (42) the drain water generated by the cooling of the exhaust gas by the air cooler (52). Thus, treated water can be used effectively and an increase in the size and the cost of the device can be prevented. |
