[0002] The desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. Its working principle is mainly based on chemical reaction to remove sulfur dioxide in flue gas. Specifically, the desulfurization tower uses a desulfurizer to make the sulfur dioxide in the flue gas react with the desulfurizer to generate calcium sulfate or other sulfur compounds, thereby achieving the purpose of removing sulfur dioxide.

[0003] A Chinese patent discloses an in-tower regeneration dry desulfurization tower (authorization announcement number CN 203598688 U).

[0026] The working principle of the utility model is as follows: when replacing the desulfurizer in the square frame 2, the uppermost motor 19 works, the motor 19 is controlled to drive the threaded rod 18 to rotate, the threaded rod 18 drives the cross bar 11 to move to the left through the threaded sleeve 10, so that the matching block 4 contacts the cross bar 11, then the motor 2 14 drives the threaded rod 2 13 to rotate, the threaded rod 2 13 drives the two threaded sleeves 2 15 to move toward the middle, the threaded sleeves 2 15 drive the insert block 16 to be inserted into the slot 5, so that the square frame 2 is fixedly connected to the cross bar 11;

[0027] Then, the uppermost motor 19 reverses and drives the crossbar 11 to move rightward, and the crossbar 11 drives the square frame 2 to move rightward, so that the uppermost square frame 2 moves out, and the square frame 2 drives the packing support mesh plate 3 and the desulfurizer to move rightward. When the packing support mesh plate 3 moves away from the tower body 1, the packing support mesh plate 3 loses its limiting force, and the packing support mesh plate 3 is affected by gravity and flips vertically to the square frame 2, so that the desulfurizer on the packing support mesh plate 3 falls down and enters the collection frame 33;

[0028] Then, the motor 19 rotates forward to drive the crossbar 11 to move a short distance to the left, so that the left end of the square frame 2 enters the tower body 1. At the same time, the filler support mesh plate 3 is affected by the through-hole limit of the tower body 1, so that the filler support mesh plate 3 rotates ninety degrees around the fixed block, and the filler support mesh plate 3 blocks the lower end of the square frame 2. At this time, most of the square frame 2 is still in the fixed frame 6, and a small part of the left end of the square frame 2 and the filler support mesh plate 3 is in the tower body 1;

[0029] Then, the motor 3 19 drives the threaded rod 3 18 to rotate, and the threaded rod 3 18 drives the lifting plate 21 to descend to the top of the square frame 2 through the threaded sleeve 3 20, and the lifting plate 21 drives the sliding pipe 25 to descend outside the fixed pipe 23, and then the valve 24 is opened, and the new desulfurizer in the storage box 22 falls into the upper end of the packing support mesh plate 3 in the square frame 2 through the fixed pipe 23 and the sliding pipe 25, completing the loading work, and then, according to the above method, the old desulfurizer on the packing support mesh plate 3 is discharged one by one and then the new desulfurizer is added, and then the motor 1 9 works to drive the square frame 2 to return to the tower body 1;

[0030] At the same time, the motor 4 30 drives the threaded rod 4 29 to rotate, and the threaded rod 4 29 drives the baffle 32 to rise through the threaded sleeve 4 31, so that the baffle 32 rises and leaves the discharge port 27, so that the residue on the tilting block 26 is discharged.
