Abstract
According to one embodiment, a carbon dioxide recovery device includes an absorption tower configured to cause carbon dioxide-containing gas to come in contact with absorbing solution and to generate rich solution absorbing the carbon dioxide, a regeneration tower configured to heat the rich solution, to disperse steam containing the carbon dioxide, and to generate lean solution from which the carbon dioxide is removed, a heat exchanging device configured to exchange heat between the lean solution and the rich solution, to supply the rich solution after the heat exchange to the regeneration tower, and to supply the lean solution after the heat exchange to the absorption tower, and a cooling device configured to cool a part of the rich solution discharged from a first place of the absorption tower and to supply the cooled rich solution to a second place higher than the first place of the absorption tower.
