[0024] By arranging four material placing bins 53 for placing the adsorbent, during use, the rotating shaft 4 is driven to rotate by the motor 3, and then the material placing box 5 is rotated as a whole, so that one of the material placing bins 53 is aligned with the ventilation hole 62, and the bottom cavity of the reactor box 1 is communicated with the exhaust pipe 11 located at the top of the reactor box 1, the flue gas is directly discharged from the exhaust pipe 11 after being desulfurized by the adsorbent in the material placing bin 53, when it is necessary to replace the ineffective adsorbent in the material placing bin 53, the material placing box 5 is rotated, so that the material placing bin 53 is rotated to the lower side of the feeding port 21 for replacement of the adsorbent powder, during the rotation of the material placing box 5, the flue gas flowing in the reactor box 1 is desulfurized by the effective adsorbent in the other material placing bins 53, so that the flue gas discharged is always desulfurized by the adsorbent, and it is not necessary to stop the machine to replace the adsorbent powder.
