[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an industrial naphthalene denitrification device, comprising a disc 1, a motor 2 fixedly connected to the upper surface of the disc 1, a rotating shaft 3 fixedly mounted at the output end of the motor 2, a bracket 4 rotatably connected to the outer wall of the rotating shaft 3, the upper surface of the bracket 4 fixedly connected to the lower surface of the disc 1, a rotating block 5 fixedly connected to the outer wall of the rotating shaft 3, a connecting shaft 6 rotatably connected to the inside of the rotating block 5, a rotating cylinder 7 fixedly connected to the outer wall of the connecting shaft 6, a first fixed shaft 8 fixedly connected to the outer wall of the rotating cylinder 7, a support block 9 rotatably connected to the outer wall of the first fixed shaft 8, a second fixed shaft 10 fixedly connected to the inside of the support block 9, the outer wall of the second fixed shaft 10 rotatably connected to the inside of the bracket 4, a support shaft 11 fixedly connected to the outer wall of the rotating cylinder 7, a spray head 12 fixedly connected to the outer wall of the support shaft 11, and a spray assembly provided on the outer wall of the disc 1, the spray assembly being used to provide a reducing agent.

[0024] Specifically, the disc 1 serves to fix the motor 2, which in turn causes the rotating shaft 3 to rotate. The bracket 4 is fixed to the lower surface of the disc 1 to support the rotating shaft 3. The rotating block 5 supports the rotating shaft 3 and the connecting shaft 6, allowing the connecting shaft 6 to drive the rotating drum 7 to rotate through the rotation of the rotating block 5. The first fixed shaft 8 connects the rotating drum 7 and the support block 9, thereby causing the support block 9 to rotate. The second fixed shaft 10 connects the support block 9 and the bracket 4, providing stable support for the rotation of the rotating drum 7. The support shaft 11 is fixed to the outer wall of the rotating drum 7 and fixes the spray head 12, thereby causing the spray head 12 to rotate. This allows for uniform spraying of industrial naphthalene gas that needs denitrification treatment, increasing the contact area to ensure a more complete reaction and improve denitrification efficiency.

[0025] Reference Figure 2 The spray assembly includes a tower body 13, the interior of which is fixedly connected to the outer wall of the disc 1, the outer wall of the motor 2 is fixedly connected to the interior of the tower body 13, a water tank 14 is fixedly connected to the interior of the tower body 13, a water pump 15 is fixedly connected to the upper surface of the water tank 14, a spray pipe 16 is fixedly connected to the output end of the water pump 15, the outer wall of the spray pipe 16 is slidably connected to the interior of the tower body 13, and the outer wall of the spray pipe 16 is fixedly connected to the interior of the spray head 12.

[0026] Specifically, the tower body 13 serves to fix and support the disc 1 and the motor 2, and also supports the water tank 14. By starting the water pump 15, the spray pipe 16 connects and transports the reducing agent inside the water tank 14 to the inside of the spray head 12 for spraying. The spray pipe 16 slides inside the tower body 13, which can stably provide the reducing agent.

[0027] Reference Figure 1 and Figure 4 An air inlet pipe 17 is fixedly connected inside the tower body 13. A limit strip 18 is fixedly connected to the outer wall of the tower body 13. A slider 19 is slidably connected to the outer wall of the limit strip 18. A first fixed column 20 is fixedly connected inside the slider 19. A rotating plate 21 is rotatably connected to the outer wall of the first fixed column 20. A second fixed column 22 is rotatably connected inside the rotating plate 21. A connecting block 23 is fixedly connected to the outer wall of the second fixed column 22. A protective plate 24 is fixedly connected to the outer wall of the connecting block 23. A column 25 is slidably connected inside the slider 19. A fixing plate 26 is fixedly connected to the outer wall of the column 25. The outer wall of the fixing plate 26 is fixedly connected to the outer wall of the tower body 13. One end of a spring 27 is fixedly connected to the outer wall of the slider 19. The other end of the spring 27 is fixedly connected to the outer wall of the fixing plate 26.

[0028] Specifically, the air inlet pipe 17 guides industrial naphthalene gas into the interior of the tower body 13. When the tower body 13 is subjected to external impact during use, the force is transmitted to the protective plate 24, which then compresses the connecting block 23. The first fixed column 20 connects the rotating plate 21 and the connecting block 23. The rotating plate 21 supports the first fixed column 20 and the second fixed column 22, allowing the second fixed column 22 to push the slider 19 to slide due to the rotation of the rotating plate 21. The limiting strip 18 is fixed to the outer wall of the tower body 13 to limit the sliding of the slider 19. The fixing plate 26 is fixed to the outer wall of the tower body 13 to fix the column 25. The slider 19 slides on the outer wall of the column 25. During this process, the spring 27 is continuously compressed and then rebounds due to the sliding of the slider 19. The spring 27 absorbs the impact force from the outside and protects the interior of the tower body 13.

[0029] Working Principle: When the denitrification device is needed, the industrial naphthalene gas to be denitrated enters the tower body 13 through the inlet pipe 17. The water pump 15 is started, and it delivers the reducing agent from the water tank 14 to the spray head 12 through the spray pipe 16 for spraying. The motor 2 on the upper surface of the disc 1 is started, driving the rotating shaft 3 to rotate inside the support 4. When the rotating shaft 3 rotates, it drives the rotating block 5 on the outer wall to rotate. The rotating block 5 drives the rotating cylinder 7 to rotate through the internal connecting shaft 6. When the rotating cylinder 7 rotates, it drives the support block 9 to rotate through the fixed shaft 8 on the outer wall. The support block 9 drives the fixed shaft 10 to rotate simultaneously inside the support 4. The rotation of the rotating cylinder 7 drives the support shaft 11 to rotate, which in turn drives the spray head 12 to rotate, uniformly spraying the industrial naphthalene gas inside the tower body 13 to ensure... The uniform distribution of the reducing agent and its full reaction enhance the denitrification efficiency. During operation, the tower body 13 is susceptible to external impacts. When the tower body 13 is subjected to external force, the impact is transmitted to the protective plate 24. The protective plate 24, through the second fixed column 22 inside the connecting block 23, drives the rotating plate 21 to rotate. The rotating plate 21, through the first fixed column 20 inside, pushes the slider 19 to slide on the outer wall of the column 25, compressing the spring 27 in the process. The continuous compression and rebound of the spring 27 absorbs the external impact, ensuring the stability of the internal structure and preventing leakage of harmful gases due to impacts, thus improving safety. This device not only achieves the effect of uniformly spraying the reducing agent onto industrial naphthalene gas to improve denitrification efficiency but also protects the tower body 13, ensuring the stability of the internal structure and enhancing safety.
