Technical Field
[0001] This invention relates to the field of environmental protection technology, specifically to a vulcanization waste gas treatment system for hydraulic hose production. Background Technology
[0002] Currently, vulcanizing tanks are used to vulcanize hydraulic hoses. Vulcanizing vapors are released into the tanks to vulcanize the hoses. However, the waste gas produced during the vulcanization process contains strong neurotoxins, which strongly irritate mucous membranes. Furthermore, some of the gases in the vulcanization waste gas are flammable and can easily form explosive mixtures when mixed with air, potentially igniting and exploding upon contact with open flames or high temperatures. In addition, this type of waste gas has a noticeable odor, causing pollution to the surrounding environment and factory area, making it difficult to avoid nuisance to residents.
[0003] Therefore, we propose a vulcanization waste gas treatment system for hydraulic hose production to solve the above problems. Summary of the Invention

The three-stage purification device 3 includes a cooling box 22, a return water inlet 23 on the side wall of the cooling box 22, a flow guide hood 28 on the top of the cooling box 22, an exhaust pipe 29 on the flow guide hood 28, an exhaust assembly 26 on the cooling box 22, a water pump 24 on the side wall of the cooling box 22, the inlet of the water pump 24 being connected to the interior of the cooling box 22, and the outlet of the water pump 24 being connected to the exhaust assembly 26 via a drain pipe 25. The exhaust port 7 is connected to the air inlet 16 via an exhaust pipe 31, the exhaust port 14 is connected to the exhaust assembly 26 via an exhaust pipe 33, the exhaust assembly 26 is connected to the water flow transmission assembly 6 via a drain pipe 32, and the overflow port 9 is connected to the return water inlet 23 via a return water pipe 34. The water pump 24, solenoid valves, heating wire 20, and pressure sensor 21 are all electrically connected to the controller 36.
[0025] The aforementioned water flow transmission assembly 6 includes a cylindrical housing 6-1 fixed inside the air inlet 5. The housing 6-1 has an inlet 6-2 on its side and an outlet 6-3 on its top. A T-shaped tube 6-4 is rotatably mounted through the axis of the housing 6-1. Multiple fan blades 6-5 and multiple fan blades 6-6 are mounted on the T-shaped tube 6-4 inside the housing 6-1. Multiple nozzles 6-7 are located at the bottom end of the T-shaped tube 6-4. The outlet 6-3 is connected to one end of a connecting pipe 6-8, and the other end of the connecting pipe 6-8 is rotatably connected to the top end of the T-shaped tube 6-4 via a rotary joint. The exhaust assembly 26 includes... A cylindrical shell 26-1 is disposed outside the cooling box 22. The shell 26-1 has an inlet 26-2 on its side and an outlet 26-3 at its end. A rotating pipe 26-4 with one open end is rotatably disposed through the axis of the shell 26-1. The rotating pipe 26-4 passes through the cooling box 22. Multiple fan blades 26-5 are disposed on the rotating pipe 26-4 located inside the shell. Multiple branch pipes 27 are disposed on the rotating pipe 26-4 located inside the cooling box 22. The inlet 26-2 is connected to the outlet 26-3 through a drain pipe 32. The exhaust pipe 33 is rotatably connected to the open end of the rotating pipe 26-4 through a rotary joint.
[0026] To facilitate the discharge of impurities generated from the exhaust gas spray cleaning, the bottom of the water tank 4 is inclined downwards towards the slag discharge port 8.
[0027] To facilitate the cleaning of impurities on the activated carbon adsorption block 18, this invention adopts the popcorn principle, that is, the adsorption tower 13 is pressurized at high temperature and then depressurized instantly to discharge the impurities on the surface of the activated carbon adsorption block 18. To facilitate the monitoring of the pressure inside the adsorption tower 13, a pressure sensor 21 is installed through the side wall of the adsorption tower 13.
[0028] To facilitate the vertical alignment of the through holes on the activated carbon adsorption block 18, a square-section through hole is provided in the middle of the activated carbon adsorption block 18, and a limiting rod 19 corresponding to the through hole is provided on the metal mesh 17.
[0029] To facilitate heat dissipation of the water inside the cooling tank 22, multiple heat dissipation fins 30 are provided through the side wall of the cooling tank 22.
[0030] To facilitate the drying of the exhaust gas after spraying, a water baffle 10 and a desiccant 11 are installed at the exhaust port 7 from bottom to top.
[0031] The specific working principle of this invention is as follows: Under normal conditions, the solenoid valves at the air inlet 16 and the air outlet 14 are both open, while the solenoid valve at the waste outlet 15 is closed. The water pump 24 is started, and the water in the cooling tank 22 is drawn by the water pump 24 and discharged from the drain pipe 25 into the housing 26-1. The water flow impacts the fan blade 26-5, causing the rotating pipe 26-4 to rotate. Then, the water flow is discharged from the outlet 26-3. After being discharged through the drain pipe, the water flow enters the housing 6-1 in the water flow transmission assembly 6. The water flow impacts the fan blade 6-5, causing the T-shaped pipe 6-4 to rotate. Then, the water flow is discharged from the outlet 6-3 and discharged into the T-shaped pipe through the connecting pipe 6-8. When the T-shaped pipe 6-4 rotates, the fan blade 6-6 rotates accordingly, introducing the exhaust gas into the water tank 4. Finally, the water flow is sprayed out from the nozzle 6-7 to spray the exhaust gas for treatment. After being sprayed, the exhaust gas is dried by the water baffle 10 and the desiccant 11 and then discharged into the adsorption tower 13 through the exhaust pipe 31. After being decomposed at high temperature and adsorbed by the activated carbon adsorption block 18, the exhaust gas is discharged from the exhaust port 14 and enters the transfer pipe 26-4 in the exhaust assembly 26 through the exhaust pipe 33. Finally, the exhaust gas is discharged from the branch pipe 27 and enters the cooling box 22 for cooling. The cooled exhaust gas is discharged from the exhaust stack 29.
[0032] Because the activated carbon adsorption block 18 will accumulate a lot of impurities on its surface after long-term use, in order to clean the impurities on the surface of the activated carbon adsorption block 18, the solenoid valves at the air inlet 16, air outlet 14 and waste outlet 15 need to be closed, the heating wire 20 is heated, and the pressure inside the adsorption tower 13 is observed by the pressure sensor 21. When the pressure inside the adsorption tower 13 reaches the set value of the controller 36, the controller 36 automatically opens the solenoid valve at the waste outlet 15. Under the state of instantaneous depressurization inside the adsorption tower 13, the impurities on the surface of the activated carbon adsorption block 18 are removed and discharged.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
