EXHAUST GAS TREATMENT DEVICE |
摘要 |
An object is to improve a NO x reduction effect by allowing an increase in the amount of exhaust gas circulated to an intake pipe and also achieve energy conservation and a CO 2 reduction by reducing a power consumption amount when NO x in exhaust gas of a diesel engine equipped with a turbocharger is removed by using an EGR system. An EGR conduit 32 that returns a part of exhaust gas e to an intake collecting pipe 13 is provided in an exhaust pipe 16 of a marine diesel engine 10A. An EGR valve 34, an EGR scrubber 36, and an EGR blower 38 are provided in the EGR conduit 32. A transmission shaft 26 of a turbocharger 20 is provided with an electric generator 40, and electric power generated by the electric generator 40 is sent to a drive motor 39 of the EGR blower 38 via a conductive wire 42 to drive the drive motor 39. An SCR catalytic converter 28 is provided in an exhaust pipe 28 on the downstream side of a turbine 22 to remove NO x in the exhaust gas e. |
