[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] See also Figures 1 to 4The utility model provides a technical solution: a novel flue gas denitrification reactor structure, comprising a reactor body 1 and a dustproof net 2, the dustproof net 2 is located inside the reactor body 1, and the side of the dustproof net 2 abuts against the inner wall of the reactor body 1, a servo motor 3 is installed on the top of the reactor body 1, a first support rod 4 is installed on the output end of the servo motor 3, the bottom of the first support rod 4 is rotatably connected to the second support rod 5 through the shaft rod, the bottom of the second support rod 5 is rotatably connected to the matching block 6 through the shaft rod, a side surface of the matching block 6 is installed with a horizontal plate 7, the bottom of the horizontal plate 7 is installed with a convex sliding block 8, and one side of the horizontal plate 7 A spring tube 9 is installed on the surface, and a return spring 10 is installed inside the spring tube 9. A spring rod 11 is installed at one end of the return spring 10. The end of the spring rod 11 away from the impact ball 12 is located inside the spring tube 9. The position of the impact ball 12 corresponds to the position of the dustproof net 2. The impact ball 12 is installed at one end of the spring rod 11. A strip plate 13 is installed on the inner bottom wall of the reactor body 1. A convex slide groove with a depth in the up and down direction and a length in the left and right direction is opened on the top of the strip plate 13. The end of the convex sliding block 8 is located inside the convex slide groove, and the convex sliding block 8 can slide along the length direction of the convex slide groove.

[0029] When in use, the flue gas enters the interior of the reactor body 1 through the dustproof net 2, and the fly ash in the flue gas is blocked by the dustproof net 2 to prevent the catalyst from accumulating ash and blocking the catalyst channels inside the reactor body 1. The dustproof net 2 is vibrated by the impact ball 12 to prevent the fly ash from blocking the mesh of the dustproof net 2. The servo motor 3 drives the first support rod 4 to rotate, and the second support rod 5 is respectively connected to the first support rod 4 and the matching block 6. The second support rod 5 and the first support rod 4 are connected to the rotation connection point to make a circular motion with the axis of the output end of the servo motor 3 as the center, so that the second support rod 5 moves, and the movement of the second support rod 5 provides a left and right direction for the matching block 6 and the cross plate 7. The force is applied upward, and the end of the convex slider 8 is located inside the convex slide groove, so that the matching block 6 drives the cross plate 7 and the convex slider 8 to move, so that the impact ball 12 moves and hits the dustproof net 2. When the impact ball 12 contacts the dustproof net 2, the reset spring 10 is forced to contract, so that the spring rod 11 moves toward the inside of the spring tube 9. When the impact ball 12 is separated from the dustproof net 2, the spring rod 11 is reset by the elastic tension of the reset spring 10, and the impact ball 12 moves back and forth to hit the dustproof net 2, which plays a role of vibrating the screen, avoiding fly ash in the flue gas from clogging the mesh of the dustproof net 2, facilitating the flue gas to enter the inside of the reactor body 1, and improving practicality.

[0031] See also Figures 1 to 6The utility model provides a technical solution: a novel flue gas denitrification reactor structure, a connecting rod 14 is installed on one side of the dustproof net 2, a positioning block 15 is installed on the end of the connecting rod 14, a limiting groove with a depth in the up-down direction is opened on the top of the positioning block 15, the end of the limiting rod 21 is inserted into the inside of the limiting groove, an adjustment box 16 is installed on the front and back of the reactor body 1, a positioning groove with a depth in the left-right direction is opened on one side of the adjustment box 16, the end of the positioning block 15 is inserted into the inside of the positioning groove, the inner wall of the adjustment box 16 is opened with a positioning slide groove with a depth in the left-right direction and a length in the up-down direction, and the end of the positioning slide 22 is opened. The positioning slider 22 is inside the positioning slot and can slide along the length direction of the positioning slot. The inside of the adjusting box 16 is rotatably connected to the round rod 17 through a bearing. The outer surface of the round rod 17 is installed with an elliptical block 18. The outer surface of the elliptical block 18 abuts against the bottom of the adjusting plate 20. The adjusting disk 23 is located outside the adjusting box 16, and the elliptical block 18 is located inside the adjusting box 16. A limiting spring 19 is installed on the inner top wall of the adjusting box 16, and an adjusting plate 20 is installed at one end of the limiting spring 19. A limiting rod 21 is installed at the bottom of the adjusting plate 20, and a positioning slider 22 is installed on one side of the limiting rod 21. An adjusting disk 23 is installed at the end of the round rod 17.

[0032] When in use, when removing and replacing the dustproof net 2, rotate the adjusting disk 23, so that the round rod 17 drives the elliptical block 18 to rotate 90 degrees, so that the elliptical block 18 rotates from the shorter end to the longer end to the adjusting plate 20. During the rotation, the adjusting plate 20 drives the limiting rod 21 and the positioning slide block 22 to move, so that the limiting spring 19 is forced to shrink, and the positioning slide block 22 slides along the length direction of the positioning slide groove, so that the end of the limiting rod 21 leaves the limiting groove, and then the connecting rod 14 is pulled to make the positioning block 15 leave the positioning groove, so that the dustproof net 2 leaves the interior of the reactor body 1, which is convenient for the removal of the dustproof net 2 and installation. During installation, the dust-proof net 2 is allowed to enter the interior of the reactor body 1, and the end of the positioning block 15 is inserted into the interior of the positioning groove. When the positioning block 15 is completely inserted into the interior of the positioning groove, the limiting groove is aligned with the limiting rod 21, and the adjusting disk 23 is rotated in the opposite direction to reset the elliptical block 18. Through the elastic tension of the limiting spring 19, the adjusting plate 20 is always in contact with the elliptical block 18. During the resetting process, the adjusting plate 20 drives the limiting rod 21 to move, so that the end of the limiting rod 21 is inserted into the interior of the limiting groove, which is convenient for limiting the position of the positioning block 15, improving the stability of the installation of the dust-proof net 2, and improving practicality.
