PROBLEM TO BE SOLVED: To provide a honeycomb rotor recovery and concentration device recovering a gas such as carbon dioxide and the like from a flue gas and the like as high as possible in a recovery rate, concentrating the gas as high as possible in concentration and using energy for recovery and concentration as small as possible in an energy amount.SOLUTION: An adsorption zone 4, a preheating zone 12, a low concentration gas purge zone 15, a desorption zone 5, a high concentration gas purge zone 16, a precooling zone 13 and a cooling zone 7 are arranged in the rotation direction of a rotor. The mixing of a low concentration gas in the desorption zone 5 and the flowing away of a high concentration gas from the desorption zone 5 are prevented. Further, the preheating zone 12 and the precooling zone 13 constitute a circulation circuit and energy saving is improved by precooling-preheating heat exchanging due to gas circulation in the circuit.SELECTED DRAWING: Figure 2 |
