Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a pipeline for waste gas engineering. Background Technology

[0002] With the continuous expansion of industrial production, environmental pollution caused by waste gas emissions is becoming increasingly serious. Many enterprises emit waste gases with complex compositions, containing a variety of harmful pollutants, such as acidic gases, organic waste gases, and sulfur-containing compounds. Traditional waste gas treatment pipelines often fall short when dealing with such complex waste gases. On the one hand, single adsorption or treatment methods are insufficient to effectively remove multiple pollutants, resulting in the treated waste gas still failing to meet emission standards. On the other hand, existing pipeline equipment presents many inconveniences in terms of maintenance. For example, complex connection methods make equipment inspection and component replacement time-consuming and labor-intensive. Moreover, most equipment lacks flexibility and cannot adjust the treatment method in a timely manner according to changes in waste gas composition. Therefore, developing a waste gas engineering pipeline that can efficiently treat multiple waste gases, is easy to maintain, and has high flexibility has become an important problem that urgently needs to be solved in the field of waste gas treatment.

[0030] Reference Figure 1-4 This utility model provides a pipeline for waste gas engineering, which includes a filter pipe 1. A fixed platform 4 is fixedly connected to the upper end of the filter pipe 1. A reagent storage box 5 is fixedly connected to both sides of the fixed platform 4. A sealing extrusion block 15 is slidably connected to the inner wall of the reagent storage box 5. A threaded sleeve 14 is fixedly connected to the upper surface of the sealing extrusion block 15. A threaded rod 9 is threadedly connected to the inner wall of the threaded sleeve 14. A worm gear 8 is fixedly connected to the outer surface of the threaded rod 9. A worm 7 is meshed with the outer surface of the worm gear 8. A rotating shaft 6 is fixedly connected to the rear end of the worm 7. A first helical gear 11 is fixedly connected to the rear end of the rotating shaft 6.

[0031] The front flange of the filter tube 1 is connected to the air outlet pipe 2, and the rear flange of the filter tube 1 is connected to the air inlet pipe 3. The upper surface of the fixed platform 4 is fixedly connected to the support platform 10. The inner wall of the support platform 10 is rotatably connected to the rotating shaft 6. The upper surface of the fixed platform 4 is fixedly connected to the drive motor 13. The output end of the drive motor 13 is fixedly connected to the second helical gear 12. The second helical gear 12 meshes with the first helical gear 11. The side end of the medicine storage box 5 is connected to the feed port 16. The lower end of the filter tube 1 is provided with the exhaust gas medicine outlet 23. The connecting pipe 17 connected to the medicine storage box 5 passes vertically through the fixed platform 4 and enters the filter tube 1.

[0032] A U-shaped tube 18 is provided at the front end of the connecting tube 17, a nozzle 19 is provided at the side end of the U-shaped tube 18, a chute 20 is provided at the lower end of the filter tube 1, an activated carbon fiber felt 21 is slidably connected inside the chute 20, and a sealing bottom cover 22 is fixedly connected at the lower end of the activated carbon fiber felt 21. There are two medicine storage boxes 5, which are symmetrically distributed.

[0033] Working principle: Exhaust gas enters the filter pipe 1 through the inlet pipe 3, and after a series of treatments, it is discharged from the outlet pipe 2. Both the inlet pipe 3 and the outlet pipe 2 are connected to the filter pipe 1 through flanges. This connection method can ensure the firmness of the pipe connection, facilitate installation and subsequent maintenance, and effectively prevent exhaust gas leakage, ensuring that the entire treatment process is carried out in a closed environment. When the drive motor 13 is started, the second helical gear 12 at the motor output end begins to rotate. Since the second helical gear 12 meshes with the first helical gear 11, the first helical gear 11 drives the rotating shaft 6 connected to it to rotate synchronously. The worm 7 at the rear end of the rotating shaft 6 also rotates. The meshing action of the worm 7 and the worm wheel 8 causes the threaded rod 9 fixed at the center of the worm wheel 8 to rotate. Because the threaded rod 9 and the threaded sleeve 14 are connected by threads, when the threaded rod 9 rotates, the threaded sleeve 14 will move up and down along the axial direction of the threaded rod 9, thereby driving the sealing extrusion block 15 to slide in the medicine storage box 5.

[0034] The two sides of the reagent storage box 5 can be filled with different types of reagents according to the complexity and composition of the waste gas. When the sealing and squeezing block 15 squeezes the reagent, the reagent flows out from the reagent storage box 5, enters the U-shaped tube 18 through the connecting pipe 17, and is finally sprayed by the nozzle 19 onto the activated carbon fiber felt 21 at the bottom of the filter tube 1. The feed port 16 can be used to replenish the reagent consumed in the reagent storage box 5 in a timely manner to ensure the continuous supply of reagent. The sprayed reagent is evenly attached to the activated carbon fiber felt 21. The activated carbon fiber felt 21 has a large specific surface area and rich pore structure, which can adsorb pollutants in the waste gas.

[0035] Simultaneously, the agents attached to the activated carbon fiber felt 21 react chemically with the pollutants in the waste gas. Selecting appropriate agents for different types of waste gas can significantly enhance the treatment effect on pollutants. For example, alkaline agents can be selected for waste gas containing acidic pollutants, while oxidizing agents can be used for waste gas containing sulfur compounds. When dealing with waste gas with complex compositions, the different agents on both sides can react and adsorb pollutants from multiple aspects, comprehensively improving treatment efficiency. As the waste gas flows within the filter tube 1, passing through the activated carbon fiber... During the process of using felt 21, pollutants are continuously adsorbed and transformed through reactions. After treatment with the reagent and adsorption by the activated carbon fiber felt 21, the pollutant content of the waste gas is significantly reduced. The purified waste gas that meets the emission standards is discharged from the outlet pipe 2. As time goes by, the waste generated after the reagent reacts with the pollutants will be discharged from the waste gas reagent outlet 23 at the lower end of the filter pipe 1 along with the falling reagent. The discharged waste can be collected for subsequent treatment to avoid secondary pollution to the environment. At the same time, it also ensures the cleanliness of the treatment environment inside the filter pipe 1 so as to continuously and efficiently treat the waste gas.

[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
