By setting the mounting shell 2, several groups of partitions 3 can be installed in the inner cavity of the desulfurization tower 1, and the filler layer 4 can be separated by the partition 3. In the present embodiment, a breathable groove 5 is provided on the surface of the partition 3, which allows the gas to flow through the filler layer 4 and be filtered.

[0024] Preferably, a feed port 6 and a discharge port 7 are respectively provided on both sides of the mounting shell 2, and a feed pipe 8 and a discharge pipe 9 are respectively installed in the inner cavities of the feed port 6 and the discharge port 7, and a plugging assembly is provided on the feed pipe 8 and the discharge pipe 9, and the plugging assembly includes a slot 10 opened on one side of the feed pipe 8 and the discharge pipe 9, and a sealing plate 11 is slidably inserted in the inner cavity of the slot 10, and one side of the sealing plate 11 passes through the slot 10 and extends to the outside of the feed pipe 8 and the discharge pipe 9 to be fixedly installed with a pull plate 12, and a locking assembly for fixing the sealing plate 11 to the inner cavity of the feed pipe 8 and the discharge pipe 9 is installed on the surface of the pull plate 12, and the locking assembly includes a locking rod 13 threadedly connected to one side of the pull plate 12, and locking holes 14 are opened on the surfaces of the feed pipe 8 and the discharge pipe 9 and at the corresponding positions of the locking rod 13, and one end of the locking rod 13 passes through the pull plate 12 and extends to the outside of the pull plate 12 and is threadedly connected to the inner wall of the locking hole 14.

[0025] Through the setting of the sealing component, when the filler in the packing layer 4 needs to be replaced, the user can open the two sets of sealing components to allow the filler in the packing layer 4 to be discharged to the outside through the discharge pipe 9. When discharged, excess space appears in the packing layer 4. At this time, the feeding component can replenish the filler into the packing layer 4 through the feed pipe 8. Through the setting of this device, the filler can be replaced without stopping the machine. After the filler is replaced, the user can reinsert the sealing plate 11 into the feed pipe 8 and the discharge pipe 9 to seal them, and tighten the locking rod 13 to lock the position of the sealing plate 11.

[0026] Among them, a feeding assembly is arranged on one side of the desulfurization tower 1 and above the feeding pipe 8, and the feeding assembly includes a feeding box 15 arranged above the feeding pipe 8, a feeding port 16 is opened at the bottom of the feeding box 15, the top end of the feeding pipe 8 is fixedly connected to the inner cavity of the feeding port 16, and a positioning frame 23 is fixedly installed on the surface of the feeding box 15, and one side of the positioning frame 23 is fixedly connected to the surface of the desulfurization tower 1.

[0029] By setting the stirring component, the filler inside the feeding box 15 can be stirred during the feeding process to prevent it from being blocked. Specifically, the user can turn on the drive motor 17 through an external controller, and the output shaft of the drive motor 17 will drive the stirring rod 20 to rotate through the rotating rod 18 and the connecting seat 19 to stir the filler in the feeding box 15.

[0030] Furthermore, the inner cavity of the feed port 16 is also equipped with an auxiliary support assembly for improving the rotation stability of the rotating rod 18.
