Description

Technical Field

[0001] The present invention relates to the technical field of waste gas purification, and more particularly to a waste gas purification device for a heat treatment carburizing furnace. Background Art

[0002] Carburizing furnace exhaust refers to the exhaust gas containing combustible organic matter and harmful gases such as sulfur dioxide generated during the carburizing process in industrial production processes such as steel, aluminum, organic chemicals, and pharmaceuticals. These exhaust gases cannot be discharged directly. They contain a large amount of gases that are harmful to the human body and require treatment before they can be discharged. Therefore, a carburizing furnace exhaust gas treatment device is needed. However, existing exhaust gas treatment devices are mostly fixed structures, which are not easy to move and flexibly install, and the exhaust gas treatment effect of these exhaust gas treatment devices is poor.

[0003] Existing waste gas treatment devices generally use a spray device to spray the waste gas treatment solution into the interior of the liquid. When the gas moves the value upward, the gas has a certain flow speed under the action of the air pump, and the contact effect between the solution and the waste gas is not ideal, resulting in poor reaction between the solution and the harmful substances in the waste gas, which in turn affects the waste gas treatment effect.

[0004] Therefore, a waste gas purification device for a heat treatment carburizing furnace is proposed. Summary of the Invention

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a waste gas purification device for a heat treatment carburizing furnace, which can vibrate a conical block. The vibration can increase the molecular movement in the solution, promote the contact and collision between the gas molecules and the reactant molecules in the solution, and at the same time, the vibration can cause the gas to form smaller bubbles in the solution, thereby increasing the surface area of ​​gas-liquid contact, thereby increasing the reaction rate and improving the waste gas treatment effect.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A heat treatment carburizing furnace exhaust gas purification device comprises a purification tower, the lower end of the purification tower is fixedly connected to an air inlet pipe, the upper end of the purification tower is fixedly connected to an exhaust pipe, and a vibration mechanism is provided inside the purification tower; The cam is connected to the air inlet pipe by the support arm and the support arm is connected with the support arm at the bottom end of the support arm, and the support arm is connected with the support arm at the bottom end of the support arm.

[0013] Preferably, a circular disc is fixedly connected to the upper end of the rod, a circular hole is opened inside the circular disc, and a rectangular plate is evenly fixed to the lower end of the circular disc.

[0014] Preferably, a drain pipe is fixedly connected to the left side of the lower end of the purification tower, and the upper end of the air inlet pipe is higher than the inner wall of the lower end of the purification tower.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) During operation, the exhaust gas impacts the blades, causing the rod to drive the support block to rotate, and then the inclined plate to rotate inside the conical block. Under the action of the first vibrating ball, the second vibrating ball and the first spring, the conical block vibrates. The vibration can increase the molecular movement in the solution and promote the contact and collision between the gas molecules and the reactant molecules in the solution.

The second spring makes the conical block move up and down more smoothly, ensuring the movement effect of the conical block and improving the treatment effect of the exhaust gas.

[0018] (4) Each time the conical block moves downward, the outside of the conical block can be cleaned to avoid excessive adhesion and affect the vibration effect of the conical block, thereby ensuring the treatment effect of the exhaust gas.

[0019] (5) When the rod rotates, it drives the disc to rotate, and the disc drives the rectangular plate to rotate, thereby diverting the exhaust gas entering the purification tower to the surrounding areas, allowing local exhaust gas to pass through the circular holes. In this way, the exhaust gas can move evenly inside the purification tower, thereby improving the exhaust gas treatment effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figures 1 to 8 A heat treatment carburizing furnace exhaust gas purification device includes a purification tower 1, the lower end of the purification tower 1 is fixedly connected to an air inlet pipe 4, the air inlet pipe 4 is used to introduce the exhaust gas into the interior of the purification tower 1, the upper end of the purification tower 1 is fixedly connected to an exhaust pipe 2, which discharges the treated gas, and the left side of the lower end of the purification tower 1 is fixedly connected to a drain pipe 5, which is used to discharge the used waste liquid. The upper end of the air inlet pipe 4 is higher than the inner wall of the lower end of the purification tower 1. A vibration mechanism is provided inside the purification tower 1, which can produce a certain vibration effect; The vibration mechanism includes a rod 25 that is rotatably connected to the inside of the air inlet pipe 4. The lower end of the rod wall of the rod 25 is fixedly connected to a blade 6. When gas is introduced into the interior of the purification tower 1 through the air inlet pipe 4, the air flow at this time has a certain flow rate under the action of the external air pump and blows towards the blade 6. The blade 6 is tilted and arranged in multiple groups to improve the rotation effect, so that the blade 6 moves. The blade 6 causes the rod 25 to rotate. The interior of the purification tower 1 is provided with a conical block 18. The interior of the conical block 18 is hollow. The conical block 18 The lower end of the inner wall is rotatably connected to a rotating plate 26, and the rotating plate 26 can rotate relative to the conical block 18. Both sides of the rotating plate 26 are fixedly connected to connecting rods 28. When the rotating plate 26 rotates, the connecting rod 28 is driven to rotate. The upper end of the connecting rod 28 is fixedly connected to a supporting block 32. The rotation of the connecting rod 28 drives the supporting block 32 to rotate. Both sides of the supporting block 32 are slidably connected to a sliding rod, and the sliding rod can move left and right relative to the supporting block 32. One side of the sliding rod is fixedly connected to a first spring 33. The first spring 33 is fixedly connected to the sliding rod when the sliding rod moves to After that, it can be reset. The back and forth sides of the two sets of slide bars are fixedly connected with inclined plates 29. The support block 32 rotates to drive the slide bar to move and then drives the inclined plate 29 to move. A first vibration ball 30 is evenly provided on one side of the inclined plate 29. The movement of the inclined plate 29 drives the first vibration ball 30 to move. The inner wall of the conical block 18 is evenly provided with a second vibration ball 31. When the first vibration ball 30 contacts the second vibration ball 31, a certain vibration can be generated. The side wall of the rotating plate 26 is fixedly connected with a cross bar 27. The cross bar 27 is movably connected to the rod 25. Component 25 drives crossbar 27 to rotate, thereby rotating plate 26. A spray assembly is provided at the upper end of the interior of purification tower 1. The spray assembly is used to spray a solution, such as an alkaline solution, such as sodium hydroxide (NaOH) or calcium hydroxide (Ca(OH)2) solution, for absorbing acidic gases in exhaust gas, such as sulfur dioxide (SO2) and hydrogen sulfide (H2S), or an oxidant solution, such as hydrogen peroxide (H2O2) or sodium hypochlorite (NaClO) solution, for treating gases containing carbon monoxide (CO). When working, the exhaust gas is introduced into the interior of the purification tower 1 through the air inlet pipe 4. When the exhaust gas passes through the air inlet pipe 4, it will impact the blade 6 to move the blade 6. The movement of the blade 6 causes the rod 25 to rotate, and the rod 25 causes the cross bar 27 to rotate. When the cross bar 27 rotates, it drives the rotating plate 26 to rotate, and the rotating plate 26 drives the connecting rod 28, thereby causing the support block 32 to rotate. The rotation of the support block 32 drives the slide bar to move, and the slide bar causes the inclined plate 29 to move. The movement of the inclined plate 29 drives the first vibration ball 30 to move. The first vibration ball 30 contacts the second vibration ball 31 when moving. Under the action of the first spring 33, the outer side of the conical block 18 produces a certain vibration effect. It should be noted that the two sides of the conical block 18 are inclined The arrangement allows the exhaust gas entering the purification tower 1 to flow along the side walls of the conical block 18, and the solution is attached to both sides of the conical block 18 through the spray assembly. In this way, when working, the exhaust gas impacts the blades 6, causing the rod 25 to drive the support block 32 to rotate, and then the inclined plate 29 to rotate inside the conical block 18. Under the action of the first vibrating ball 30, the second vibrating ball 31 and the first spring 33, the conical block 18 vibrates. The vibration can increase the molecular movement in the solution and promote the contact and collision between the gas molecules and the reactant molecules in the solution. At the same time, the vibration can cause the gas to form smaller bubbles in the solution, thereby increasing the surface area of ​​gas-liquid contact, thereby increasing the reaction rate and improving the exhaust gas treatment effect.

[0024] like Figure 2-4 As shown, the inner wall of the purification tower 1 is fixedly connected with a sealing ring 15, and the sealing ring 15 is provided to improve the sealing effect. The swivel 16 will not leak when it rotates. The inner wall of the sealing ring 15 is rotatably connected with the swivel 16, and the swivel 16 can rotate relative to the sealing ring 15. The left side of the sealing ring 15 is fixedly connected with a liquid inlet pipe 3, which is used to pass the solution into the interior of the purification tower 1. The inner wall of the swivel 16 is fixedly connected with a pipe fitting 17, and a nozzle 34 is provided at the center of the pipe fitting 17 and the lower end of the sealing ring 15. The nozzle 34 is used to spray liquid, and the lower end of the nozzle 34 extends downward and toward the side of the conical block 18, so that the solution can be sprayed to the outside of the conical block 18 evenly. The center of the pipe fitting 17 is movably connected to the rod 25; When the rod 25 rotates, the pipe 17 is driven to rotate. When the pipe 17 rotates, the swivel 16 is driven to rotate. When the swivel 16 rotates, the nozzle 34 is driven to rotate. The nozzle 34 extends downward, so that the sprayed liquid can be evenly sprayed on the outer surface of the conical block 18, thereby enabling the exhaust gas to better contact with the solution, thereby improving the reaction effect and further improving the exhaust gas treatment effect.

[0025] like Figure 3 and Figure 4As shown, a reciprocating groove is provided at the upper end of the rod 25, and a moving block 35 is meshedly connected to the outer side of the reciprocating groove. When the rod 25 rotates, the reciprocating groove rotates, thereby enabling the meshing connected moving block 35 to move back and forth up and down. Both sides of the moving block 35 are fixedly connected to support rods 11, and both sides of the purification tower 1 are provided with chutes 8. The interior of the chutes 8 is slidably connected to sliders 9, and the sliders 9 can move inside the chutes 8. The sliders 9 are fixedly connected to the support rods 11, and the upper end of the support rods 11 is fixedly connected to a vertical rod 36. The vertical rod 36 is used for connecting and supporting, and the upper end of the vertical rod 36 is fixedly connected to the lower end of the tapered block 18; When the rod 25 rotates, the reciprocating groove rotates, and the rotation of the reciprocating groove causes the moving block 35 to move back and forth up and down. The moving block 35 drives the support rod 11 to move up and down, and the rotation of the support rod 11 drives the vertical rod 36 to move up and down. When the vertical rod 36 moves, it drives the conical block 18 to move up and down. The slider 9 and the smooth groove 8 are set to enable the conical block 18 to move up and down stably, and have a certain limiting effect in the direction of rotation, so as to prevent the conical block 18 from rotating when the rod 25 rotates. In this way, during operation, the reciprocating groove allows the conical block 18 to move up and down stably. When the conical block 18 moves up and down, it can change the path of the airflow, making the flow of the exhaust gas entering the purification tower 1 more turbulent, improving the contact effect between the exhaust gas and the solution, and improving the treatment effect of the exhaust gas.

[0026] like Figure 4 As shown, the upper end of the rod 25 is fixedly connected to the rectangular rod 24, and the rod wall of the rectangular rod 24 is slidably connected to the inside of the cross bar 27. The rectangular rod 24 can move up and down relative to the cross bar 27, and when the rectangular rod 24 rotates, it drives the cross bar 27 to rotate. The upper end of the rectangular rod 24 is fixedly connected to the pipe 17. When the rod 25 rotates, it drives the rectangular rod 24 to rotate, thereby causing the pipe 17 to rotate, and the rectangular rod 24 and cross bar 27 to rotate. Because the rectangular rod 24 itself is rectangular when it rotates, the rectangular rod 24 can drive the cross bar 27 to rotate, and can also move up and down relative to the rectangular rod 24.

[0027] like Figure 6 As shown, the lower end of the slider 9 is fixedly connected to the second spring 10. The second spring 10 has an upward supporting force on the slider 9. When the conical block 18 moves up and down, it overcomes gravity when moving upward. Through the second spring 10, when the conical block 18 moves up and down, the gravitational potential energy of the conical block 18 and the elastic potential energy of the second spring 10 can be continuously converted, thereby making the conical block 18 smoother when moving up and down, ensuring the movement effect of the conical block 18, thereby ensuring the exhaust gas treatment effect.

[0028] like Figure 4 and Figure 7As shown, the inner wall of the purification tower 1 is fixedly connected with a first ring 12, and the upper end of the first ring 12 is rotatably connected with a second ring 13, and the second ring 13 can rotate relative to the first ring 12. The upper end of the second ring 13 is provided with a round rod 14. When the round rod 14 moves, the second round rod 14 is driven to rotate. The upper end of the round rod 14 is fixedly connected to the pipe 17, and the upper end of the second ring 13 is fixedly connected with a rectangular block 21. The interior of the rectangular block 21 is slidably connected with a scraper 23, and the scraper 23 can move up and down relative to the rectangular block 21. The lower end of the scraper 23 is fixedly connected with a third spring 22, and the third spring 22 has an upward supporting force on the scraper 23. The scraper 23 is arranged parallel to the conical block 18. When the conical block 18 moves downward, it can contact the scraper 23; When the swivel 16 rotates, it drives the vertical rod 36 to move. When the vertical rod 36 moves, it drives the second ring 13 to rotate. The rotation of the second ring 13 drives the rectangular block 21 to rotate, and then drives the scraper 23 to rotate. In this way, when the conical block 18 moves downward, it will contact the scraper 23, and the scraper 23 will rotate relative to the conical block 18. In this way, the outside of the conical block 18 can be cleaned every time the conical block 18 moves downward, avoiding excessive attachments that affect the vibration effect of the conical block 18, thereby ensuring the exhaust gas treatment effect.

[0029] like Figure 2 and Figure 8 As shown, the upper end of the rod 25 is fixedly connected to the disc 7, and the inside of the disc 7 is provided with a circular hole 19 for allowing the exhaust gas to pass through. The lower end of the disc 7 is evenly fixed with a rectangular plate 20; When the rod 25 rotates, the disc 7 is driven to rotate, and the disc 7 drives the rectangular plate 20 to rotate, thereby guiding the exhaust gas entering the purification tower 1 to the surroundings, allowing local exhaust gas to pass through the circular hole 19, so that the exhaust gas can move evenly inside the purification tower 1, thereby improving the exhaust gas treatment effect.

[0030] Working principle: When working, the exhaust gas is introduced into the interior of the purification tower 1 through the air inlet pipe 4. When passing through the air inlet pipe 4, the other exhaust gas will impact the blade 6. The movement of the blade 6 causes the rod 25 to rotate, and the rod 25 causes the cross bar 27 to rotate. When the cross bar 27 rotates, it drives the rotating plate 26 to rotate, and the rotating plate 26 drives the connecting rod 28, thereby causing the support block 32 to rotate. The rotation of the support block 32 drives the slide bar to move, and the slide bar causes the inclined plate 29 to move. The movement of the inclined plate 29 drives the first vibration ball 30 to move. The first vibration ball 30 contacts the second vibration ball 31 when moving. Under the action of the first spring 33, the outer side of the conical block 18 produces a certain vibration effect. It should be noted that the two sides of the conical block 18 are inclined The exhaust gas entering the purification tower 1 can flow along the side walls of the conical block 18, and the solution is attached to both sides of the conical block 18 through the spray assembly. In this way, when the exhaust gas impacts the blades 6, the rod 25 drives the support block 32 to rotate, and then the inclined plate 29 rotates inside the conical block 18. Under the action of the first vibration ball 30, the second vibration ball 31 and the first spring 33, the conical block 18 vibrates. The vibration can increase the molecular motion in the solution and promote the contact and collision between the gas molecules and the reactant molecules in the solution. At the same time, the vibration can cause the gas to form smaller bubbles in the solution, thereby increasing the surface area of ​​gas-liquid contact, thereby increasing the reaction rate and improving the exhaust gas treatment effect. Furthermore, when the rod 25 rotates, the pipe 17 is driven to rotate, and when the pipe 17 rotates, the swivel 16 is driven to rotate, and when the swivel 16 rotates, the nozzle 34 is driven to rotate. The nozzle 34 extends downward, so that the sprayed liquid can be evenly sprayed on the outer surface of the conical block 18, thereby enabling the exhaust gas to better contact with the solution, thereby improving the reaction effect and further improving the exhaust gas treatment effect. When the lever 25 is rotated, the reciprocating groove is rotated, and the rotation of the reciprocating groove causes the moving block 35 to move up and down reciprocatingly, and the moving block 35 drives the support rod 11 to move up and down, and the rotation of the support rod 11 drives the vertical rod 36 to move up and down, and when the vertical rod 36 moves, it drives the conical block 18 to move up and down. The slider 9 and the smooth groove 8 are provided, so that the conical block 18 can move up and down stably. In this way, when working, the reciprocating groove allows the conical block 18 to move up and down stably. When the conical block 18 moves, the exhaust gas entering the purification tower 1 can be more turbulent, thereby improving the contact effect between the exhaust gas and the solution and improving the treatment effect of the exhaust gas. Through the second spring 10, when the conical block 18 moves up and down, the gravitational potential energy of the conical block 18 and the elastic potential energy of the second spring 10 are continuously converted, thereby making the conical block 18 smoother when moving up and down, ensuring the movement effect of the conical block 18, thereby ensuring the treatment effect of the exhaust gas; Furthermore, when the rotating ring 16 rotates, it drives the vertical rod 36 to move, and when the vertical rod 36 moves, it drives the second ring 13 to rotate. The rotation of the second ring 13 drives the rectangular block 21 to rotate, and then drives the scraper 23 to rotate. In this way, when the conical block 18 moves downward, it will contact the scraper 23, and the scraper 23 will rotate relative to the conical block 18. In this way, the outside of the conical block 18 can be cleaned every time the conical block 18 moves downward, avoiding excessive attachments that affect the vibration effect of the conical block 18, thereby ensuring the exhaust gas treatment effect.
