The invention belongs to the field of related equipment of the carbon capture technology and particularly relates to a rotary cyclic carbon capture device and method based on three-bed reaction. The rotary cyclic carbon capture device comprises a rotating shaft and one or more sets of circulatory reaction units, wherein each set of circulatory reaction unit comprises three reactors which are arranged side by side in the circumferential direction of the rotating shaft and are uniformly distributed; a cavity is formed in each reactor and used for placing an absorbent; a gas inlet is formed in the top of each reactor; a gas outlet is formed in the bottom of each reactor; and each gas inlet and the corresponding gas outlet are communicated with the cavity in the corresponding reactor. The invention further discloses a method adopting the rotary cyclic carbon capture device to perform circulatory carbon capture. The problem of adsorption performance degradation caused by the reasons that pores are reduced by high-temperature sintering of a calcium-based absorbent and the pore structures are destroyed by CaSO4 impurities generated by a SO2 reaction is solved, meanwhile, the problem of abrasion of an absorbent is solved, the energy consumption is greatly reduced, and the rotary cyclic carbon capture device is compact in structure and has the advantages of high economical efficiency, excellent environmental friendliness and the like.
