Harmful gases enter the housing 1 from the air inlet 2, pass through the air holes 6 in each filter material bracket 4, and then exit the housing 1 from the discharge port 3. The desulfurizing agent and denitrifying agent treat the harmful gases. When it is necessary to remove the desulfurizing agent or denitrifying agent from the housing 1, the mounting bracket 8 is removed from the mounting port 7, thereby pulling the filter material bracket 4 out of the housing 1. Then, the cover 5 is opened. The opening of the cover 5 is large, which makes it very convenient to remove the desulfurizing agent or denitrifying agent from the filter material bracket 4.

[0022] Example 2: Based on Example 1, in order to realize the opening and closing of the cover 5, the bottom end of the cover 5 is rotatably connected to the filter material bracket 4. The filter material bracket 4 is provided with a handle groove 17. The cover 5 is fixed with a cover mounting plate 18. The handle groove 17 is provided with a cover screw hole 19. The cover mounting plate 18 is rotatably connected with a cover screw 20. The cover screw 20 is installed in the cover screw hole 19 by thread connection.

[0023] Remove the cap screw 20 from the cap screw hole 19, then insert your finger into the handle groove 17. You can then place your finger on the side of the cap 5 and rotate the cap 5 to open it. Rotate the cap 5 in the opposite direction so that the cap mounting plate 18 on the cap 5 is inserted back into the handle groove 17. This allows the cap screw 20 to be reinstalled into the cap screw hole 19 via the threaded connection, thus closing the cap 5.

[0024] Example 3: Based on Example 2, in order to prevent harmful gases from escaping from the gap between the mounting port 7 and the mounting frame 8, a sealing groove 12 is provided on the mounting frame 8. The sealing groove 12 is provided around the mounting frame 8, and a sealing plate 13 is fixed in the sealing groove 12.

[0025] A sealing plate 13 is fixed in the sealing groove 12 opened on the mounting bracket 8. The sealing plate 13 is made of rubber. The outer ring of the sealing plate 13 abuts against the inner wall of the mounting port 7 to seal the gap between the mounting port 7 and the mounting bracket 8, which can prevent harmful gases from escaping from the gap between the mounting port 7 and the mounting bracket 8.

[0026] Example 4: Based on Example 3, in order to replace the sealing plate 13, the mounting frame 8 is provided with a lifting rod hole 9, the filter material bracket 4 is fixed with a lifting rod 10, the lifting rod 10 is movably inserted into the lifting rod hole 9, the top of the lifting rod 10 is movably installed with a lifting ring 14, the top of the lifting rod 10 is fixed with a lifting ring screw 16, the bottom of the lifting ring 14 is provided with a lifting ring screw hole 15, the lifting ring screw 16 is installed in the lifting ring screw hole 15 by threaded connection, the lifting rod 10 is a round rod structure, a positioning plate 11 is sleeved and fixed on the rod body of the lifting rod 10, and the top of the positioning plate 11 abuts against the bottom of the mounting frame 8.

[0027] When the sealing plate 13 is severely worn and can no longer effectively seal the gap between the mounting port 7 and the mounting bracket 8, remove the mounting bracket 8 from the mounting port 7, rotate the lifting ring 14 to remove the lifting ring screw 16 from the lifting ring screw hole 15, and then remove the old mounting bracket 8 from the lifting rod 10. Insert the lifting rod 10 into the lifting rod hole 9 on the new mounting bracket 8 with the sealing plate 13 installed. Position the mounting bracket 8 with the positioning plate 11, then install the lifting ring 14 back onto the lifting ring screw 16, and install the mounting bracket 8 back into the mounting port 7. This allows for quick replacement of the sealing plate 13, avoiding prolonged impact on the use of the equipment.

[0028] In actual use, the filter material brackets 4 filled with desulfurizing agent are inserted into the mounting ports 7 near the air inlet 2, and the filter material brackets 4 filled with denitrifying agent are inserted into the mounting ports 7 near the discharge port 3. Harmful gases enter the housing 1 from the air inlet 2, pass through the air holes 6 in sequence through the filter material brackets 4, and then exit the housing 1 from the discharge port 3. The desulfurizing and denitrifying agents treat the harmful gases. When it is necessary to remove the desulfurizing or denitrifying agent from the housing 1, the mounting bracket 8 is inserted from the mounting port 7. Remove the filter material from the housing 1, thereby causing the filter material holder 4 to exit. Then open the cover 5. The cover 5 has a large opening, making it easy to remove the desulfurizing agent or denitrifying agent from the filter material holder 4. Remove the cover screw 20 from the cover screw hole 19, then insert your finger into the handle groove 17. You can then place your finger on the side of the cover 5 and rotate the cover 5 to open it. Rotate the cover 5 in the opposite direction to allow the cover mounting plate 18 on the cover 5 to re-insert into the handle groove 17, thus opening the cover screw. 20. The cover 5 can be closed by threading it back into the screw hole 19 of the cover. A sealing plate 13 is fixed in the sealing groove 12 on the mounting bracket 8. The sealing plate 13 is made of rubber. The outer ring of the sealing plate 13 abuts against the inner wall of the mounting port 7 to seal the gap between the mounting port 7 and the mounting bracket 8, preventing harmful gases from escaping from the gap between the mounting port 7 and the mounting bracket 8. When the sealing plate 13 is severely worn and can no longer effectively seal the gap between the mounting port 7 and the mounting bracket 8, the mounting bracket 8 can be removed. Remove the old mounting bracket 8 from the mounting port 7, rotate the lifting ring 14 to remove the lifting ring screw 16 from the lifting ring screw hole 15, and then remove the old mounting bracket 8 from the lifting rod 10. Insert the lifting rod 10 into the lifting rod hole 9 on the new mounting bracket 8 with the sealing plate 13 installed. Position the mounting bracket 8 with the positioning plate 11. Then install the lifting ring 14 back onto the lifting ring screw 16 and install the mounting bracket 8 back into the mounting port 7. This allows for a quick and easy replacement of the sealing plate 13, avoiding prolonged disruption to the equipment's operation.
