CARBON DIOXIDE RECOVERY DEVICE, AND METHOD FOR TREATING EXHAUST GAS

WIPO Patent Application WO/2015/186725

A1

　The CO2 recovery device (10A) according to the present invention is provided with: an absorption column (11), a regeneration column (12), and a cleaning unit (27). The absorption column (11) is provided with a CO2 absorption unit (24) for causing a lean solution (22) containing an amino-group-containing compound to make gas-liquid contact with an exhaust gas (21) containing CO2, and causing the CO2 to be absorbed by the lean solution (22). The regeneration column (12) separates the CO2 contained in a rich solution (23) and regenerates the rich solution (23). The cleaning unit (27) removes the amino-group-containing compound from the CO2-removed exhaust gas (28) from which CO2 was removed by the CO2 absorption unit (24). A cleaning unit (27) is equipped with a catalyst part (31) in which a photocatalyst is supported on a support having gas-permeable voids, an activation member for activating the photocatalyst, and a power-source part (33). The activation member is a pair of electrodes comprising a first electrode (32-1) and a second electrode (32-2).
