To provide a carbon dioxide recovery system capable of reducing an amount of amine to be discharged to the atmosphere.SOLUTION: A carbon dioxide recovery system according to an embodiment includes a carbon dioxide recovery part which makes an absorption liquid containing amine absorb carbon dioxide contained in combustion exhaust gas, and a first cleaning part which cleans the combustion exhaust gas discharged from the carbon dioxide recovery part with mist of a first cleaning liquid injected by an injector and recovers the amine accompanied by the combustion exhaust gas. The carbon dioxide recovery system includes a cleaning liquid mist recovery part which recovers the mist of the first cleaning liquid accompanied by the combustion exhaust gas discharged from the first cleaning part.SELECTED DRAWING: Figure 1 【課題】アミンの大気中への放出量を低減することができる二酸化炭素回収システムを提供する。【解決手段】実施の形態による二酸化炭素回収システムは、燃焼排ガスに含有される二酸化炭素を、アミンを含有する吸収液に吸収させる二酸化炭素回収部と、二酸化炭素回収部から排出される燃焼排ガスを、噴射器で噴射した第１洗浄液のミストで洗浄して、燃焼排ガスに同伴するアミンを回収する第１洗浄部と、を備えている。また、二酸化炭素回収システムは、第１洗浄部から排出される燃焼排ガスに同伴する第１洗浄液のミストを回収する洗浄液ミスト回収部を備えている。【選択図】図１
