Japanese Patent JPH0512535
Kind Code:
B2
Abstract:
PURPOSE:To improve the circulation regeneration efficiency for carbon-dioxide absorbent and permit the use in water for a long period by making the intake and exhaust pipe systems of an engine into perfect circulation closed system and properly treating the exhaust gas supplied from an engine and adding pure oxygen and again supplying said exhaust gas into the engine. CONSTITUTION:After the exhaust gas (c) supplied from an engine 1 is cooled by cooling water (d) in an exhaust cooling apparatus 11, in the captioned apparatus, the carbon dioxide in the exhaust gas is absorption-removed through the contact with the carbon-dioxide absorbing liquid (e) in a gas liquid contact part 15. Oxygen (f) is mixed into the gas treated with the above-described treatment in an oxygen mixer 19, and the supplied gas a' is obtained, and this gas is supplied into the engine 1 through a supplied gas heating apparatus 10. In the above, a carbon dioxide gas absorbent regenerating apparatus 100 which heats the aqueous solution supplied from an aqueous solution taking-out means 25 for taking out the absorbent liquid (e) which absorbs carbon dioxide, in utilization of exhaust gas heat, and separates carbon dioxide gas and absorbent liquid is equipped, and the heating-treated absorbent liquid is recovered into a tank 16 through a gas liquid separator 120.
