Claim:
1. A carbon dioxide capture system comprising: an absorber having a first gas-liquid contact unit configured to bring exhaust gas and an absorbing liquid into contact with each other to cause carbon dioxide contained in the exhaust gas to be absorbed in the absorbing liquid; and a stripper configured to permit the carbon dioxide to be released from the absorbing liquid containing the carbon dioxide, the absorbing liquid being supplied from the absorber, wherein the absorber further has: a release region which is provided above the first gas-liquid contact unit, into which the absorbing liquid supplied from the stripper is introduced, and which is configured to allow the carbon dioxide to be released from the absorbing liquid; a second gas-liquid contact unit which is provided above the release region, and into which the carbon dioxide released in the release region is supplied together with the exhaust gas discharged from the first gas-liquid contact unit; an absorbing liquid supply device by which the absorbing liquid having released the carbon dioxide therefrom in the release region is supplied to the second gas-liquid contact unit; and a guide member configured to guide the absorbing liquid to the first gas-contact unit while bypassing the release region, the absorbing liquid having passed through the second gas-liquid contact unit, and wherein the second gas-liquid contact unit is configured to bring the exhaust gas and the absorbing liquid into contact with each other so as to cause the carbon dioxide contained in the exhaust gas to be absorbed in the absorbing liquid.
