[0021] By installing a rotatable flip cover 3 on the top of the desulfurization tower 1, the smoke guide pipe 4 on the flip cover 3 can be quickly connected with the exhaust port 2 chassis, ensuring that the smoke in the desulfurization tower 1 can be discharged smoothly. When the positioning ring 10 in the desulfurization tower 1 needs to be disassembled, the dial ring 9 can be rotated to allow the dial ring 9 to drive the threaded sleeve 8 to move upward along the threaded column 7, and then the threaded column 7 is dialed to allow the threaded column 7 to rotate along the rotating seat 6, so that the threaded column 7 drives the threaded sleeve 8 to leave the positioning groove 5 on the flip cover 3, so that the threaded sleeve 8 quickly releases the rotation limit effect on the flip cover 3, and then the flip cover can be opened. Cover 3, pull out the filter cartridge 12 in the desulfurization tower 1. When the filter cartridge 12 needs to be installed, the two groups of positioning blocks 13 on the filter cartridge 12 can be aligned with the two groups of positioning holes 11 on the positioning ring 10 and inserted. Then, the flip cover 3 drives the positioning groove 5 to rotate to the rotating seat 6, and then the threaded column 7 is turned to allow the threaded column 7 to rotate into the positioning groove 5. Then, the dial ring 9 is rotated to allow the dial ring 9 to drive the threaded sleeve 8 to rotate, and the threaded sleeve 8 moves downward under the action of the thread, thereby locking the positioning groove 5, quickly forming a steering limit for the flip cover 3, and quickly completing the replacement of the filter cartridge 12.

[0023] By installing a liftable support plate 18 at the bottom of the exhaust port 2, when the exhaust port 2 needs to be connected to an external pipeline, the connecting end of the external pipeline can be placed on the support plate 18 first, and then the handle 16 is twisted to rotate the threaded rod 15, and the threaded tube 17 drives the support plate 18 to move upward under the guidance of the thread and the guide rod 19, so that the support plate 18 drives the pipeline thereon to gradually align with the exhaust port 2, without spending a lot of time on manual correction, and without lifting the pipeline during the installation process, so that the exhaust port 2 can be quickly connected to the external pipeline, thereby improving the convenience of using the device.

[0024] In other embodiments, the diameter of the threaded sleeve 8 is larger than the inner width of the positioning groove 5;

[0025] Through this design, the threaded sleeve 8 can move to the bottom of the positioning groove 5 to form a rotation limiting effect on the flip cover 3.

[0026] In other embodiments, the outer wall of the positioning block 13 is fully fitted with the inner wall of the positioning hole 11 on the positioning ring 10;

[0027] This design prevents the positioning block 13 from shaking inside the positioning hole 11 , thereby improving the stability of the filter cartridge 12 during use.

[0028] In other embodiments, the outer wall of the turning handle 16 is provided with a plurality of anti-slip grooves at equal intervals along the axis of the turning handle 16;

[0029] This design can effectively increase the friction between the handlebar 16 and the user's hand, making it easier to effectively rotate the handlebar 16.
