The invention relates to a rotating bed of overweight field of baffled gas-liquid cross flowing type. The shell of the invention is divided into an upper cavity and a lower cavity by a separating plate; a sealing device is arranged between the separating plate and the upper end plate; a gas outlet and a liquid inlet are respectively communicated with the upper cavity; the gas inlet and the liquidoutlet are respectively communicated with the lower cavity; a rotary shaft goes through the shell; the rotor consists of the upper end plate, a lower end plate, an upper concentric circle, a lower concentric circle and a liquid distributor which are fixedly connected with the rotary shaft, wherein, the upper concentric circle and the lower concentric circle are crossly positioned in the rotor to form a devious S-shaped baffled passage; the upper concentric circle and the lower concentric circle are provided with the small holes corresponding to the liquid outlet holes on the liquid distributor in axial direction; the gas inlet and the liquid outlet are communicated with the S-shaped passage; one end of a liquid guide pipe is communicated with the upper end of the liquid distributor while the other end with liquid inlet. The invention has the advantage of excellent mass transfer capability which reduces the rotational energy consumption and pressure.
