<P>PROBLEM TO BE SOLVED: To provide an exhaust gas treatment device capable of efficiently operating a scrubber provided in an exhaust gas recirculation passage. <P>SOLUTION: This exhaust gas treatment device 1 is provided at exhaust gas recirculation passages 27, 31 branching exhaust gas from a second exhaust gas passage 25 where the exhaust gas discharged after the completion of the combustion in a ship diesel engine 3 flows and leading it to a scavenging route 19 for supplying air for combustion to the ship diesel engine 3. The exhaust gas treatment device 1 includes: a scrubber 23 removing PM and sulfur oxide in the exhaust gas led from the second exhaust gas passage 25; and an exhaust gas cooler 24 provided above the scrubber 23, for cooling the exhaust gas after the removal of the PM and the sulfur oxide. <P>COPYRIGHT: (C)2012,JPO&INPIT |
