The desulfurized flue gas passes through the first filter screen 19, the second filter screen 22 and the third filter screen 23 in sequence. The flue gas is filtered by multiple filters, and the filtered flue gas enters the regeneration cylinder 6 through the exhaust pipe 15. A slot 25 is opened in the second filter screen 22. A third filter screen 23 is provided on the top of the second filter screen 22. An insertion rod 24 is fixedly connected to the bottom of the third filter screen 23.

[0025] In this embodiment, as Figure 1 and Figure 2As shown, a stirring rod 17 is fixedly connected to the output end of the drive motor 14. The stirring rod 17 extends into the fixed cylinder 18 and is rotatably connected to the fixed cylinder 18. Flue gas is introduced into the fixed cylinder 18 through the air inlet pipe 13. Then, under the action of the drive motor 14, the stirring rod 17 is driven to rotate. The rotation of the stirring rod 17 can make the catalyst and flue gas react quickly, which is convenient for desulfurizing the flue gas. A feed cover 12 is abutted on one side of the desulfurization cylinder 4, and an air inlet pipe 13 is fixedly connected to the other side of the desulfurization cylinder 4. A side groove 10 is opened in the desulfurization cylinder 4, and a cover plate 9 is abutted in the side groove 10. A pull ring 11 is fixedly connected to the outer surface of the cover plate 9. An air outlet pipe 15 is fixedly connected to the bottom of the desulfurization cylinder 4. A valve 16 is provided on the outside of the air outlet pipe 15.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, a regeneration cylinder 6 is fixedly connected inside the fixing ring 5. The regeneration cylinder 6 is connected to the outlet pipe 15.

This allows the filters to be detachably fixed, making it convenient to clean and maintain them.

[0029] The working process of this utility model is as follows: When the coke oven flue gas desulfurization and regeneration integrated tower designed in this scheme is in operation, the feed cover 12 is opened to allow the catalyst to enter the fixed cylinder 18, and then the flue gas is introduced into the fixed cylinder 18 through the air inlet pipe 13. Then, under the action of the drive motor 14, the stirring rod 17 is driven to rotate. The rotation of the stirring rod 17 can make the catalyst and flue gas react quickly, which facilitates the desulfurization of the flue gas. The desulfurized flue gas passes through the first filter screen 19, the second filter screen 22 and the third filter screen 23 in sequence. The flue gas is filtered through multiple filters, and the filtered flue gas enters the regeneration cylinder 6 through the air outlet pipe 15 to complete the desulfurization and regeneration of the coke oven flue gas.
