[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] Please see Figures 1-3 In this embodiment of the utility model, a flue gas dispersion device for a flue gas neutralization tower includes a fixed plate 1. The fixed plate 1 has a plurality of connecting holes 2 equidistantly spaced in the circumference. The connecting holes 2 are connected to a gas guide pipe 3 through a connecting mechanism. The top opening of the gas guide pipe 3 is formed with a hexagonal groove 4. The lower part of the inner wall of the gas guide pipe 3 is provided with a screw hole 8. A limiting mechanism is rotatably installed at the bottom end of the fixed plate 1. The limiting mechanism is used to limit the bottom end of the connecting mechanism.
[0014] In this embodiment: when the flue gas flows upward from the top of the fixed plate 1, the flue gas flows upward through the inner wall of the gas guide pipe 3, so as to achieve uniform dispersion and upward flow of flue gas. When the neutralization tower is maintained, the gas guide pipe 3 can be disassembled through the connecting mechanism for separate cleaning, without the need to move the entire fixed plate 1 and clean the entire fixed plate 1. Before disassembling the gas guide pipe 3, the limiting mechanism can be rotated so that the limiting mechanism no longer supports the bottom end of the connecting mechanism. Then, an internal hex wrench can be used to connect with the hexagonal slot 4, and then the gas guide pipe 3 can be driven to rotate, so as to separate the gas guide pipe 3 from the connecting mechanism.
[0015] Please refer to this carefully. Figure 2 and Figure 3The connecting mechanism includes a connecting tube 5 threaded to the inner wall of the screw hole 8. The bottom end of the connecting tube 5 is integrally formed with a hexagonal head 6. The lower part of the fixed plate 1 is provided with a first docking groove 9 that communicates with the connecting hole 2. The hexagonal head 6 is inserted into the inner wall of the first docking groove 9.
[0016] In this embodiment: When installing the air guide tube 3, first insert the connecting tube 5 into the inner wall of the connecting hole 2, and insert the hexagonal head 6 into the first docking groove 9. Then rotate the limiting mechanism to support the bottom of the connecting mechanism. Then thread the screw hole 8 at the bottom of the inner wall of the air guide tube 3 to the outer wall of the connecting tube 5, and use an internal hex wrench to dock with the inner wall of the hexagonal groove 4. Then the air guide tube 3 can be driven to rotate by the internal hex wrench to achieve convenient connection between the air guide tube 3 and the connecting tube 5.
[0017] Please refer to this carefully. Figure 2 and Figure 3 The limiting mechanism includes a limiting ring 7 rotatably mounted on the bottom end of the fixed plate 1. The top of the limiting ring 7 is integrally formed with an upwardly protruding rotating ring. The bottom end of the fixed plate 1 is provided with a rotating groove for the rotating ring to rotate. The inner wall of the limiting ring 7 is provided with a second docking groove 10. The inner wall of the second docking groove 10, the inner wall of the first docking groove 9, and the outer wall of the hexagonal head 6 form a regular hexagonal structure. The height of the first docking groove 9 is equal to the thickness of the hexagonal head 6.
[0018] In this embodiment: after the hexagonal head 6 is fully inserted into the first docking groove 9, a rotational force is applied to the limiting ring 7. The limiting ring 7 causes the second docking groove 10 to be misaligned with the hexagonal head 6. At this time, the hexagonal head 6 can be made by the limiting ring 7 to prevent it from falling.
[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
