Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment, and in particular to a flow guiding mechanism for flue gas denitrification. Background Technology

[0002] Flue gas denitrification and upgrading devices are key equipment designed to reduce nitrogen oxide emissions generated during combustion. These devices are commonly used in industrial boilers, power plants, and waste incineration facilities to meet increasingly stringent environmental standards. Within a flue gas denitrification system, the flow guiding mechanism is a crucial auxiliary device used to optimize flue gas flow patterns and ensure efficient denitrification reactions. Its core function is to guide the flue gas into a uniform and stable flow state within the denitrification reactor (especially in the catalyst zone) through a rational structural design, thereby improving denitrification efficiency and protecting the equipment.

[0003] Existing flow guiding mechanisms cannot adjust the angle of the flow guide plate. Generally, the flow guide plate of a flow guiding mechanism is fixedly installed on the inner wall of the flue, and the angle is fixed, making it difficult to adjust flexibly as needed. This reduces the effect of flue gas treatment, reduces practicality and applicability, and is inconvenient to use and maintain. Generally, the flow guide plate is installed inside the flue, and when maintaining the flow guide plate, the entire flue needs to be disassembled, the flow guide plate needs to be maintained, and then the flue needs to be reassembled. The maintenance process is relatively troublesome, increases the workload, and reduces the maintenance efficiency. In order to solve the above problems, we propose a flow guiding mechanism for flue gas denitrification. Utility Model Content

[0004] The purpose of this invention is to provide a flow guiding mechanism for flue gas denitrification, which has the advantages of being able to adjust the angle of the flow guide plate and being easy to maintain.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a flue gas denitrification guiding mechanism, including a flue pipe, a plurality of guide plates rotatably sleeved between the inner walls of the flue pipe, a fixed shell bolted to the surface of the flue pipe, a worm gear rotatably sleeved between the inner walls of the fixed shell, a worm wheel meshing at the bottom of the worm gear, and the axis of the worm wheel being fixedly sleeved with one end of the guide plate, a fixing mechanism provided on the surface of the worm gear, a cover plate hinged to the surface of the flue pipe, a slide rod slidably connected to the inner wall of the cover plate, two snap-fit ​​joints bolted to the surface of the slide rod, two snap-fit ​​holes opened on the inner wall of the flue pipe, and the snap-fit ​​joints snapping into the snap-fit ​​holes, a spring provided between the slide rod and the inner wall of the cover plate, and a toggle block bolted to the surface of the slide rod.

[0006] By adopting the above technical solution, the worm gear is rotated by loosening the bolts and turning the rotating head. The rotation of the worm gear drives the worm wheel to rotate, which in turn drives the guide plate to rotate. The rotation of the guide plate changes its angle, thus achieving the purpose of adjusting the guide plate angle. This improves practicality and applicability, ensures the treatment effect, and facilitates use. Moving the toggle block causes the slide rod to move the snap-fit ​​connector. The movement of the snap-fit ​​connector disengages it from the snap-fit ​​hole, allowing the cover plate to be opened for maintenance. This method facilitates maintenance, reduces workload, and improves maintenance efficiency.

[0007] The present invention is further configured such that: the fixing mechanism includes a fixing block, the fixing block is rotatably sleeved with the surface of the worm gear, and the fixing block is bolted to the surface of the fixing shell; the inner wall of the fixing block is threaded with a bolt, and the inner end of the bolt is in contact with the surface of the worm gear.

[0008] By adopting the above technical solution, a fixing mechanism is set up to fix the worm gear, prevent loosening, and improve stability.

[0009] The present invention is further configured such that a rotating head is bolted to one end of the worm gear.

[0010] By adopting the above technical solution, a rotating head is provided to facilitate the rotation of the worm gear.

[0011] The present invention is further configured such that: the surface of the worm gear is rotatably sleeved with multiple fixing plates, and the fixing plates are bolted to the surface of the flue.

[0012] By adopting the above technical solution, the worm gear is fixed by setting a fixing plate, thereby improving stability.

[0013] The present invention is further configured such that one end of the card connector is wedge-shaped.

[0014] By adopting the above technical solution, one end of the snap-fit ​​connector is wedge-shaped, which facilitates the fixing of the cover plate.

[0015] The present invention is further provided with a sealing gasket between the cover plate and the flue.

[0016] By adopting the above technical solution, a sealing gasket is installed to prevent air leakage.

[0017] The present invention is further configured such that: a connecting ring is fixedly sleeved at the top and bottom of the flue, and the surface of the connecting ring is provided with a plurality of connecting holes.

[0018] By adopting the above technical solution, the connection to flue gas ducts and reactors can be facilitated by setting connecting rings and connecting holes.

[0019] The present invention is further configured such that the surface of the actuating block is provided with anti-slip texture.

[0020] By adopting the above technical solution, anti-slip texture is set to prevent hand slippage and facilitate operation.

[0021] In summary, this utility model has the following beneficial effects: 1. This utility model achieves the purpose of adjusting the angle of the guide plate by loosening the bolts, rotating the rotating head to make the worm rotate, the worm rotating to drive the worm wheel to rotate, the worm wheel rotating to make the guide plate rotate, and the rotation of the guide plate changing the angle of the guide plate. This improves practicality and applicability, ensures the treatment effect, and is convenient to use. 2. This utility model uses a movable toggle block to move the slide rod, which in turn moves the snap-fit ​​connector. The snap-fit ​​connector moves and disengages from the snap-fit ​​hole, allowing the cover plate to be opened for maintenance. This method facilitates maintenance, reduces workload, and improves maintenance efficiency. Attached Figure Description

A worm wheel 5 meshes with the bottom of the worm gear 4, and the axis of the worm wheel 5 is fixedly sleeved with one end of the guide plate 2. A fixing mechanism 6 is provided on the surface of the worm gear 4. By loosening the bolt 14 and rotating the rotating head 15, the worm gear 4 is rotated. The rotation of the worm gear 4 drives the worm wheel 5 to rotate, which in turn causes the guide plates 2 to rotate. The rotation of the guide plates 2 changes the angle of the guide plates 2, thereby achieving the purpose of adjusting the angle of the guide plates 2, improving practicality and applicability, ensuring the treatment effect, and facilitating use.

[0026] refer to Figure 5 The fixing mechanism 6 includes a fixing block 13, which is rotatably sleeved with the surface of the worm 4 and bolted to the surface of the fixing shell 3. The inner wall of the fixing block 13 is threaded with a bolt 14, and the inner end of the bolt 14 contacts the surface of the worm 4. By setting the fixing mechanism 6, the worm 4 is fixed to prevent loosening and improve stability.

[0027] refer to Figure 1 and Figure 5 One end of the worm 4 is bolted with a rotating head 15, which facilitates the rotation of the worm 4.

[0028] refer to Figure 3 Multiple fixing plates 16 are rotatably sleeved on the surface of the worm 4, and the fixing plates 16 are bolted to the surface of the flue 1. By setting the fixing plates 16, the worm 4 is fixed and the stability is improved.

[0029] refer to Figure 1 The top and bottom of the flue pipe 1 are fixedly fitted with connecting rings 18. The surface of the connecting rings 18 is provided with multiple connecting holes 19. By setting the connecting rings 18 and connecting holes 19, it is convenient to connect with the flue gas pipe and the reactor.

[0030] Example 2: refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 A cover plate 7 is hinged to the surface of the flue pipe 1. A slide rod 8 is slidably connected to the inner wall of the cover plate 7. Two snap-fit ​​connectors 9 are bolted to the surface of the slide rod 8. Two snap-fit ​​holes 10 are opened on the inner wall of the flue pipe 1, and the snap-fit ​​connectors 9 snap into the snap-fit ​​holes 10. A spring 11 is provided between the slide rod 8 and the inner wall of the cover plate 7. A toggle block 12 is bolted to the surface of the slide rod 8. By moving the toggle block 12, the slide rod 8 drives the snap-fit ​​connectors 9 to move. The movement of the snap-fit ​​connectors 9 causes the snap-fit ​​connectors 9 to disengage from the snap-fit ​​holes 10, allowing the cover plate 7 to be opened for maintenance. This method facilitates maintenance, reduces workload, and improves maintenance efficiency.

[0031] refer to Figure 6 One end of the snap-fit ​​connector 9 is wedge-shaped, which facilitates the fixing of the cover plate 7.

[0034] Brief description of the usage process: Install the flue pipe 1 between the flue gas duct and the reactor inlet. When adjusting the angle of the guide plate 2, loosen the bolt 14 and rotate the rotating head 15. The rotation of the rotating head 15 drives the worm gear 4 to rotate, which in turn drives the worm wheel 5 to rotate, which in turn drives the guide plate 2 to rotate, thus changing the angle of the guide plate 2. After adjustment, tighten the bolt 14 to fix the worm gear 4, thereby achieving the purpose of adjusting the angle of the guide plate 2. During maintenance, move the actuating block 12. The movement of the actuating block 12 drives the sliding rod 8 to move, which in turn drives the snap-fit ​​connector 9 to move. The snap-fit ​​connector 9 disengages from the snap-fit ​​hole 10. Open the cover plate 7 to maintain the guide plate 2. After maintenance, close the cover plate 7. Under the action of the spring 11, the sliding rod 8 drives the snap-fit ​​connector 9 to snap into the snap-fit ​​hole 10, fixing the cover plate 7. The sealing gasket 17 seals it, thus greatly facilitating maintenance.

[0035] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
