Description

Technical Field

[0001] This utility model belongs to the field of ammonia spraying structures, and specifically relates to a dynamically adjustable ammonia spraying structure. Background Technology

[0002] Flue gas denitrification (FGD) technologies mainly include dry methods (selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) FGD) and wet methods. Compared with wet FGD, the main advantages of dry FGD are: lower initial investment, simpler equipment and processes, higher NOx removal efficiency, no wastewater or waste treatment, and less likelihood of secondary pollution. Current FGD technologies typically use ammonia or urea as reducing agents, reducing nitrogen oxides (NOx) to nitrogen and water through selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR) technologies. However, existing ammonia injection systems mainly consist of fixed nozzle designs and simple pipeline layouts. These designs lack flexibility and cannot be adjusted according to real-time changes in flue gas velocity and NOx concentration, resulting in insufficient mixing of ammonia and flue gas and low FGD efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a dynamically adjustable ammonia injection structure, which has the advantages of facilitating flexible adjustment of the ammonia injection structure, increasing the flexibility and scheduling of use, and realizing the adjustment of the nozzle angle. This setting further improves the flexibility of the ammonia injection structure, and also enables flexible adjustment according to the real-time changes in flue gas velocity and NOx concentration, thereby ensuring denitrification efficiency.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dynamically adjustable ammonia spraying structure, including branch pipes, wherein there are multiple branch pipes, and a wave tube is connected between adjacent two branch pipes. A collar is fixedly sleeved on the surface of the branch pipe, a crossbar is provided on one side of the collar, and a shifting ring is provided at one end of the collar to sleeve the surface of the crossbar. A collar is fixedly sleeved on the top of the surface of the branch pipe, and an installation block is fixedly installed on the surface of the collar. An installation block is provided inside the installation block, and a collar is fixedly installed on the top of the installation block. A nozzle is fixedly installed inside the collar, and one end of the nozzle is connected to a wave tube connected to one end of the branch pipe.

[0005] The above technical solution involves the following steps: When using the dynamically adjustable ammonia injection structure, the installation is first performed using a mounting plate in conjunction with a crossbar at the desired position. The mounting plate is secured with external bolts through mounting holes. During ammonia injection, the main pipe connects to an external ammonia supply unit, transmitting ammonia to the inside of the waveguide and then into the branch pipe. When adjusting the distance between the branch pipe and the nozzle, the screw is rotated by turning knob one. The threaded hole engages with the screw for threaded fastening. The screw's progressive movement within the shift ring creates contact friction with the crossbar surface. After the screw releases contact, the shift ring can be moved to the crossbar surface. Once the branch pipe and nozzle are in the desired position, knob one is tightened again, allowing the screw to move progressively within the threaded hole. Once the screw contacts the crossbar surface, the branch pipe is fixed in place. This design facilitates flexible adjustment of the ammonia injection structure, increasing its usability and scheduling. Simultaneously, the angle of the nozzle can be adjusted when using the dynamically adjustable ammonia injection structure. The operator rotates knob two, causing it to move progressively across the surface of screw two, thus adjusting the angle between mounting block one and mounting block two. After adjusting the nozzle to the appropriate position, knob two can be tightened again. During the movement of knob two across the surface of screw two, one side of mounting block two is pressed against the inner side of mounting block one, and knob two is pressed against the front side of mounting block one. This achieves a tight locking between mounting block one and mounting block two, thereby completing the nozzle angle adjustment. This setting further enhances the flexibility of the ammonia injection structure, allowing for flexible adjustment based on real-time changes in flue gas velocity and NOx concentration, thus ensuring denitrification efficiency.

[0006] The present invention is further configured such that the bottom of the wave tube located in the middle position of the branch tube is connected to the main tube.

[0007] The above technical solution involves transmitting the signal through the main pipe to the inner side of the waveguide, and then into the branch pipe.

[0008] The present invention is further configured such that a connecting block is fixedly installed between the collar and the moving ring.

[0009] The above technical solution is adopted: the connection and installation between the collar and the moving ring is achieved by the connecting block.

[0010] The present invention is further configured such that a screw is provided at the top of the moving ring, and the bottom of the screw extends through to the inner side of the moving ring and contacts the crossbar.

[0011] By adopting the above technical solution, the contact friction between the screw and the crossbar surface will be achieved through the progressive movement of the screw inside the moving ring.

[0012] The present invention is further configured such that a threaded hole is provided on the inner side of the moving ring for threaded connection with a screw, and a knob is fixedly installed on the top of the screw.

[0013] The above technical solution is adopted: the screw is used for threaded fastening through the threaded hole, and the knob is used for rotation through the screw.

[0014] The present invention is further configured such that mounting plates are fixedly installed at both ends of the crossbar, and mounting holes are provided inside the mounting plates.

[0015] The above technical solution involves installing the mounting plate in conjunction with the crossbar at the required position, with the mounting holes used in conjunction with external bolts to secure the mounting plate.

[0016] The present invention is further configured such that a screw rod 2 extending through to the front side of the mounting block 1 is fixedly installed on one side of the mounting block 2, and a knob 2 located on the front side of the mounting block 1 is threadedly connected to the surface of the screw rod 2.

[0017] The above technical solution is adopted: by rotating the second knob, the screw rod can be moved forward through the threaded connection, thereby achieving contact with the front side of the first mounting block.

[0018] The present invention is further configured such that a shaft extending through to the rear side of the first mounting block is fixedly installed on the other side of the second mounting block, and a limiting block located on the rear side of the first mounting block is fixedly installed at one end of the shaft.

[0019] The above technical solution is adopted: the angle between the shaft and the mounting block 2 and the mounting block 1 is adjusted, and the limiting block and the shaft are positioned to limit the position inside the mounting block 1.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. When using the dynamically adjustable ammonia spraying structure, this utility model is first installed using the mounting plate in conjunction with the crossbar at the desired position. During ammonia spraying, the main pipe is connected to an external ammonia supply device. When it is necessary to adjust the distance between the branch pipe and the nozzle, the screw can be rotated by turning knob one, which then moves the position of the shift ring on the crossbar surface. After moving the branch pipe and nozzle to the desired position, knob one is tightened again, allowing the screw to move progressively within the threaded hole. Once the screw contacts the crossbar surface, the branch pipe is fixed in place. This design facilitates flexible adjustment of the ammonia spraying structure, increasing its flexibility and operability.

[0022] 2. In the use of the dynamically adjustable ammonia injection structure, the angle of the nozzle can be adjusted. The operator can adjust the angle between mounting block one and mounting block two by rotating knob two. After the nozzle is adjusted to the appropriate position, knob two can be tightened again, thus achieving a secure stop between mounting block one and mounting block two, thereby completing the nozzle angle adjustment. This setting further improves the flexibility of the ammonia injection structure, allowing for flexible adjustment based on real-time changes in flue gas velocity and NOx concentration, thereby ensuring denitrification efficiency.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] refer to Figure 1 and Figure 2A dynamically adjustable ammonia injection structure includes multiple branch pipes 2. Adjacent branch pipes 2 are interconnected by a waveguide 3. A collar 6 is fixedly fitted onto the surface of each branch pipe 2. A crossbar 4 is located on one side of the collar 6, and a shift ring 8, which is fitted onto the surface of the crossbar 4, is located at one end of the collar 6. When using the dynamically adjustable ammonia injection structure, it is first installed using a mounting plate 5 in conjunction with the crossbar 4 to the desired position. Subsequently, during ammonia injection, the main pipe 1 is connected to an external ammonia supply device. When it is necessary to adjust the distance between the branch pipes 2 and the nozzle 19, the screw 10 can be rotated by turning the knob 9, which then moves the shift ring 8 on the surface of the crossbar 4. After moving the branch pipe 2 and the nozzle 19 to the desired position, tighten the knob 9 again to allow the screw 10 to move progressively inside the threaded hole 11. Once the screw 10 contacts the surface of the crossbar 4, the branch pipe 2 can be fixed in place. This setting facilitates flexible adjustment of the ammonia spraying structure, increasing its flexibility and scheduling.

[0031] refer to Figure 1 The bottom of the wave tube 3, located in the middle of the branch tube 2, is connected to the main tube 1. The main tube 1 transmits the signal to the inside of the wave tube 3 and then into the branch tube 2.

[0032] refer to Figure 2 A connecting block 7 is fixedly installed between the collar 6 and the moving ring 8, and the connection between the collar 6 and the moving ring 8 is achieved through the connecting block 7.

[0033] refer to Figure 2 The top of the moving ring 8 is provided with a screw 10. The bottom of the screw 10 extends through the inside of the moving ring 8 and contacts the crossbar 4. Through the progressive movement of the screw 10 inside the moving ring 8, contact friction with the surface of the crossbar 4 is achieved.

[0034] refer to Figure 2 The inner side of the moving ring 8 is provided with a threaded hole 11 that is threaded to the screw 10. A knob 9 is fixedly installed on the top of the screw 10. The screw 10 is tightened by threading through the threaded hole 11, and the knob 9 is rotated by the screw 10.

[0035] refer to Figure 1 Both ends of the crossbar 4 are fixedly installed with mounting plates 5. The mounting plates 5 have mounting holes 12 inside. The mounting plates 5 are used to install the crossbar 4 in the required position. The mounting holes 12 are used with external bolts to secure the mounting plates 5.

[0036] Brief description of usage: When using the dynamically adjustable ammonia spraying structure, the mounting plate 5 is first installed in conjunction with the crossbar 4 at the desired position. The mounting hole 12, with the external bolts, secures the mounting plate 5. During ammonia spraying, the main pipe 1 connects to the external ammonia supply equipment, transmitting ammonia to the inside of the waveguide 3 and then into the branch pipe 2. When adjusting the distance between the branch pipe 2 and the nozzle 19, the screw 10 can be rotated by turning the knob 9. The threaded hole 11 engages with the screw 10 for threaded fastening. As the screw 10 moves inward within the shift ring 8, it contacts the surface of the crossbar 4. After the screw 10 releases contact with the surface of the crossbar 4, the position of the shift ring 8 on the surface of the crossbar 4 can be adjusted. After moving the branch pipe 2 and the nozzle 19 to the desired position, tighten the knob 9 again to allow the screw 10 to move progressively inside the threaded hole 11. Once the screw 10 contacts the surface of the crossbar 4, the branch pipe 2 can be fixed in place. This setting facilitates flexible adjustment of the ammonia spraying structure, increasing its flexibility and scheduling.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 3 and Figure 4 A dynamically adjustable ammonia spraying structure includes a branch pipe 2. A collar 2 13 is fixedly sleeved on the top of the surface of the branch pipe 2. A mounting block 14 is fixedly installed on the surface of the collar 2 13. A mounting block 2 15 is provided on the inner side of the mounting block 14. A collar 3 20 is fixedly installed on the top of the mounting block 2 15. A nozzle 19 is fixedly installed on the inner side of the collar 3 20. One end of the nozzle 19 is connected to a waveguide 21 connected to one end of the branch pipe 2. During the use of the dynamically adjustable ammonia spraying structure, the angle of the nozzle 19 can be adjusted. The operator can adjust the angle between the mounting block 1 14 and the mounting block 2 15 by rotating the knob 2 22. After adjusting the nozzle 19 to the appropriate position, the knob 22 can be tightened again. This will achieve the locking and limiting between mounting block 14 and mounting block 25, thereby completing the angle adjustment of the nozzle 19. This setting further improves the flexibility of the ammonia injection structure and allows for flexible adjustment based on real-time changes in flue gas velocity and NOx concentration, thus ensuring denitrification efficiency.

[0039] refer to Figure 4 A screw rod 18 is fixedly installed on one side of the mounting block 14, extending through to the front side of the mounting block 14. A knob 22 located on the front side of the mounting block 14 is threadedly connected to the surface of the screw rod 18. By rotating the knob 22, the screw rod 18 moves forward through the threaded connection, thereby making contact with the front side of the mounting block 14.

[0040] refer to Figure 4On the other side of mounting block 2 15, a shaft 16 is fixedly installed, extending through to the rear side of mounting block 1 14. One end of the shaft 16 is fixedly installed with a limiting block 17 located on the rear side of mounting block 1 14. The shaft 16 is used to adjust the angle between mounting block 2 15 and mounting block 1 14, and the limiting block 17 is used to limit the position of the shaft 16 inside mounting block 1 14.

[0041] Brief Description of Usage: When using the dynamically adjustable ammonia injection structure, the angle of the nozzle 19 can be adjusted. The operator rotates knob 22, causing it to move progressively across the surface of screw 18. During this movement, the angle between mounting block 14 and mounting block 15 can be adjusted. After the nozzle 19 is adjusted to the appropriate position, knob 22 can be tightened again. As knob 22 moves across the surface of screw 18, one side of mounting block 15 is pressed against the inner side of mounting block 14, and knob 22 is pressed against the front side of mounting block 14. This achieves a tight locking between mounting block 14 and mounting block 15, thus completing the angle adjustment of the nozzle 19. This setting further improves the flexibility of the ammonia injection structure, allowing for flexible adjustment based on real-time changes in flue gas velocity and NOx concentration, thereby ensuring denitrification efficiency.
