Summary:To provide a carbon dioxide recovery system capable of reducing a discharge amount of amine.SOLUTION: A carbon dioxide recovery system includes a carbon dioxide recovery part, an absorption liquid regeneration part, a first cleaning part, a second cleaning part, and an absorption liquid line. The first cleaning part cleans a combustion exhaust gas discharged from the carbon dioxide recovery part with mist of first cleaning liquid jet by a first jetting device, and recovers amine accompanying the combustion exhaust gas. The absorption liquid line supplies absorption liquid regenerated in the absorption liquid regeneration part as a first cleaning liquid, to the first jetting device. The first cleaning liquid jet by the first jetting device as the absorption liquid is supplied to the carbon dioxide recovery part.SELECTED DRAWING: Figure 1 【課題】アミンの排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、二酸化炭素回収部と、吸収液再生部と、第1洗浄部と、第2洗浄部と、吸収液ラインと、を備えている。第1洗浄部は、二酸化炭素回収部から排出される燃焼排ガスを、第1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。吸収液ラインは、吸収液再生部において再生された吸収液を、第1洗浄液として第1噴射器に供給する。第1噴射器で噴射された第1洗浄液は、吸収液として二酸化炭素回収部に供給される。【選択図】図1
