PURPOSE:To accomplish energy saving for elimination of carbon dioxide by using cooling water for an engine and exhaust gas as a heating source for regenerating absorbing solution for eliminating carbon dioxide in exhaust gas of the titled Diesel engine used for a submerged power source or the like. CONSTITUTION:Exhaust gas from a Diesel engine 1 is passed through a passage A, conducted to a turbine of a supercharger to drive the turbine, and then circulated to a suction port 1B through a heat exchanger 3, a cooler 4, a filter 5, a blower 6 of the supercharger and the cooler 4. At this time, in order to eliminate carbon dioxide contained in exhaust gas in the passage A, the exhaust gas is drawn out by a fan 12, conducted to an absorbing tower 13 to absorb carbon dioxide in an absorbing solution. Rich absorbing solution E where carbon dioxide is absorbed is sent to a heat exchanger 14 to be preheated, further heated by the respective heat exchangers 9, 3 using cooling water of an engine cooling water passage B and exhaust gas in the passage A, and then flashed into a diffusion tower 17 under reduced pressure to bleed off carbon dioxide. |
