Description

Technical Field

[0001] The present invention relates to the field of flue gas treatment, and particularly to a chemical flue gas treatment device. Background Art

[0002] Chemical flue gas is a mixture of gas and soot, with complex components, usually including water vapor, sulfur dioxide, etc. The emission of flue gas is one of the causes of air pollution, so it is crucial to treat chemical flue gas before emission.

[0003] During treatment, chemical flue gas is generally introduced into the treatment liquid to absorb and remove harmful gases in the chemical flue gas by using the treatment liquid, so as to achieve the purpose of purifying the flue gas. However, during the actual treatment process, when the chemical flue gas is introduced into the treatment liquid, the flue gas will directly overflow and discharge. At this time, the contact time between the flue gas and the treatment liquid is short, resulting in insufficient contact between the two, that is, part of the flue gas does not contact the treatment liquid when discharging, resulting in a small amount of harmful gases still remaining in the treated flue gas, and the treatment effect is not good. Summary of the Invention

[0008] Preferably, a sleeve is slidably installed on the outer surface of the hook frame. The end of the sleeve is fixed to the L-shaped shell. A lug cap is coaxially inlaid on the outer surface of the cover frame. The lug cap is slidably installed inside the column shell. An opening spring is wound around the outside of the cover frame. One end of the opening spring is fixed to the lug cap. The other end of the opening spring is fixed to the inner side surface of the column shell. A guide post is slidably installed through the middle of the push cap seat. The lower end of the guide post is fixedly installed with a column seat. The end of the column seat is fixed to the L-shaped shell. The opening spring is in a tensioned state.

[0009] Preferably, the extrusion rod penetrates from the upper end into the inside of the extrusion head. The extrusion rod is slidably matched with the extrusion head. A convex block is fixedly installed at the lower end of the extrusion rod. The convex block is slidably installed inside the extrusion head. A fitting spring is fixedly installed at the lower end of the convex block. The end of the fitting spring is fixed to the inner bottom surface of the extrusion head.

[0010] Preferably, the reciprocating pushing member includes a push seat slidably installed through the upper end near the edge of the processing box. A connecting seat is fixedly installed at the lower end of the push seat. A plurality of push frames are fixedly installed in a linear array at the lower end of the connecting seat. The extrusion rod and the extending frame are respectively fixed to both ends of the push frame. A second bearing shaft is rotatably installed at the upper edge of the front end of the processing box. A swing frame is fixedly installed at the end of the second bearing shaft. A connecting rod is rotatably installed at the end of the swing frame. The end of the connecting rod is rotatably connected to the push seat.

[0011] Preferably, the flow pushing member includes a plate shaft rotatably installed inside the processing box near the L-shaped shell. The plate shaft penetrates out from the front end of the processing box. A plurality of flow pushing plates are arranged in a circular array on the outer surface of the plate shaft.

[0012] Preferably, a first bearing shaft is rotatably installed above the plate shaft at the front end of the processing box. A large gear is coaxially inlaid at the front end of the first bearing shaft. A small gear is coaxially inlaid at the front end of the plate shaft. The large gear meshes with the small gear. A servo motor is fixedly installed above the front end of the processing box far from the first bearing shaft. Belt pulleys are coaxially inlaid on the output end of the servo motor, the outer surface of the second bearing shaft, and the outer surface of the first bearing shaft. A belt is connected between the three belt pulleys.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By means of the rotating second bearing shaft, the swing frame can be driven to rotate, and then the connecting rod is driven to move, enabling the pushing seat to continuously reciprocate up and down. When the pushing seat moves downward, the extrusion rod and the extension frame will be driven to move downward synchronously. At this time, the downward-moving extrusion rod will push the extrusion head, so as to push the chemical industrial flue gas located in the vertical section inside the L-shaped shell downward through the extrusion head, and make it be extruded into the treatment liquid in the horizontal section inside the L-shaped shell. When the pushing of the extrusion head is completed, the positioning ear just abuts against the positioning seat, preventing the extrusion head from continuing to move. At the same time, the pressure ear on the extension frame presses on the push cap seat. Subsequently, the pushing seat continues to drive the extrusion rod and the extension frame to move downward. At this time, the extrusion rod slides downward inside the extrusion head and adapts to the spring contraction deformation, so that the downward movement operation is not hindered. The downward-moving extension frame will press on the push cap seat through the pressure ear, causing it to move downward, and then driving the inclined frame to move, so as to push the cap rod, enabling the discharge cap on the cap rod to slide inside the horizontal section of the L-shaped shell. At the same time, the moving cap rod will also drive the hook frame to move, causing the hook frame to move laterally, so as to loosen the pulling on the hook ear, allowing the opening spring to gradually recover its deformation, so as to push open the sealing cover and open the side end of the L-shaped shell, enabling the discharge cap to push out the treatment liquid dissolved with the chemical industrial flue gas during the sliding process. Subsequently, the pushing seat moves upward. At this time, the extrusion rod slides upward inside the extrusion head and adapts to the spring gradually recovering its deformation. When the convex block slides to the top of the extrusion head, the extrusion rod will use the convex block to lift the extrusion head, causing the extrusion head to move upward and reset, allowing the chemical industrial flue gas in the intake pipe to enter the vertical section inside the L-shaped shell. At the same time, when the extension frame moves upward, the top ear on it will abut against the lower end of the push cap seat to lift the push cap seat, causing the discharge cap to slide back to its original position. During the reset process, the treatment liquid around the side end of the L-shaped shell will enter the horizontal section inside the L-shaped shell again. When the discharge cap is completely reset, the end of the hook frame will pull on the hook ear again, pressing the sealing cover on the L-shaped shell for sealing. By cycling in this way, the chemical industrial flue gas is continuously extruded, enabling it to quickly dissolve in the treatment liquid, allowing the chemical industrial flue gas and the treatment liquid to fully contact, and enabling the harmful gases in the chemical industrial flue gas to be fully absorbed and removed by the treatment liquid, thereby improving the treatment effect.

[0015] 2. When the servo motor drives the second bearing shaft to rotate, it will also drive the large gear on the first bearing shaft to rotate, and then drive the small gear to rotate rapidly, enabling the flow pushing plate on the plate shaft to push the treatment liquid at the side end of the L-shaped shell, making it flow, so that all the treatment liquid in the treatment tank can flow to the L-shaped shell and enter the inside of the L-shaped shell, thereby ensuring the full utilization of the treatment liquid in the treatment tank.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a technical solution: As Figures 1-8A chemical flue gas treatment device shown in the figure includes a treatment tank 1. A plurality of L-shaped shells 16 are fixedly installed in a linear array on the inner bottom surface of the treatment tank 1. An extrusion head 17 is slidably installed through the upper end of the L-shaped shell 16. A reciprocating pushing member is provided through the top of the treatment tank 1. The extrusion head 17 can continuously extrude the chemical flue gas, enabling it to quickly dissolve in the treatment liquid, allowing the chemical flue gas and the treatment liquid to come into full contact. Both ends of the reciprocating pushing member are respectively connected to an extrusion rod 18 and an extension frame 21. The extrusion rod 18 is elastically connected to the extrusion head 17. A pressing ear 22 extends near the middle of the side surface of the extension frame 21, and a top ear 23 extends at the lower edge of the side surface of the extension frame 21. A push cap seat 41 is slidably installed on the side of the L-shaped shell 16. The pressing ear 22 can press the push cap seat 41, enabling the discharge cap 30 to push out the treatment liquid dissolved with the chemical flue gas. The push cap seat 41 is attached to the upper end of the top ear 23, and the top ear 23 can lift the push cap seat 41 to reset the discharge cap 30. The end of the push cap seat 41 is rotatably installed with an inclined frame 40, and the end of the inclined frame 40 is rotatably installed with a cap rod 31. One end of the cap rod 31 slidably penetrates through the inside of the L-shaped shell 16. A discharge cap 30 is slidably installed in the horizontal section inside the L-shaped shell 16. The push cap seat 41 can drive the inclined frame 40 to move, so as to push the cap rod 31, and then drive the discharge cap 30 to move. The discharge cap 30 is fixed to one end of the cap rod 31. A sealing cover 29 is elastically installed at the side end of the L-shaped shell 16. The sealing cover 29 can block the L-shaped shell 16 to increase the extrusion force. A positioning ear 19 extends at the upper edge of the side surface of the extrusion head 17, and a positioning seat 20 extends at the upper edge of the side surface of the L-shaped shell 16. A flow pushing member is arranged inside the treatment tank 1 near the L-shaped shell 16. The positioning ear 19 and the positioning seat 20 play a role in positioning the downward movement height of the extrusion head 17.

[0027] An air inlet pipe 2 is inlaid through the middle of the front end of the treatment tank 1. The air inlet pipe 2 is communicated with a plurality of L-shaped shells 16. A liquid discharge port 4 is provided through the lower part of one side of the treatment tank 1, and a liquid inlet 12 is provided through the upper part of the other side of the treatment tank 1. The liquid discharge port 4 and the liquid inlet 12 play a role in replacing the treatment liquid. An air outlet pipe 3 is provided through the upper edge of the upper end of the treatment tank 1. Valves can be installed on the air inlet pipe 2, the air outlet pipe 3, the liquid discharge port 4, and the liquid inlet 12 to control the opening and closing.

[0028] A cover frame 43 is fixedly installed on the side surface of the sealing cover 29. A column shell 28 is slidably installed on the outer surface of the cover frame 43. The cover frame 43 plays a role in connecting the sealing cover 29. The column shell 28 is fixed to the L-shaped shell 16. A hook ear 27 extends at the end of the cover frame 43. The column shell 28 and the cover frame 43 play a role in guiding the sealing cover 29. A hook frame 25 is fixedly installed at the other end of the cap rod 31. The end of the hook frame 25 abuts against the side surface of the hook ear 27. The hook frame 25 can pull the hook ear 27, causing the sealing cover 29 to move towards the L-shaped shell 16 to block the L-shaped shell 16.

[0029] A sleeve 26 is slidably mounted on the outer surface of the hook frame 25. The end of the sleeve 26 is fixed to the L-shaped shell 16. The sleeve 26 serves to guide the hook frame 25. A lug cap 34 is coaxially inlaid on the outer surface of the cover frame 43. The lug cap 34 is slidably mounted inside the column shell 28. The lug design on the lug cap 34 can prevent the cover frame 43 from rotating. An opening spring 35 is wound around the outside of the cover frame 43. One end of the opening spring 35 is fixed to the lug cap 34, and the other end of the opening spring 35 is fixed to the inner side surface of the column shell 28. When the hook frame 25 does not pull the hook ear 27, the opening spring 35 will push the lug cap 34, separating the sealing cover 29 from the L-shaped shell 16 and allowing the treatment liquid dissolved with chemical flue gas in the L-shaped shell 16 to be discharged. A guide post 24 is slidably mounted through the middle of the push cap seat 41. The lower end of the guide post 24 is fixedly mounted with a column base 42. The end of the column base 42 is fixed to the L-shaped shell 16. The opening spring 35 is in a tensioned state. The guide post 24 serves to guide the push cap seat 41, and the column base 42 serves to fix the guide post 24.

[0030] The extrusion rod 18 penetrates from the upper end into the inside of the extrusion head 17. The extrusion rod 18 is in sliding fit with the extrusion head 17. A convex block 32 is fixedly mounted at the lower end of the extrusion rod 18. The convex block 32 is slidably mounted inside the extrusion head 17. The convex block 32 can lift the extrusion head 17 when the extrusion rod 18 moves upward, causing the extrusion head 17 to move upward and reset. A fitting spring 33 is fixedly mounted at the lower end of the convex block 32. The end of the fitting spring 33 is fixed to the inner bottom surface of the extrusion head 17. When the extrusion head 17 finishes pushing, the positioning ear 19 just abuts against the positioning seat 20, preventing the extrusion head 17 from moving further. Subsequently, the push seat 9 continues to drive the extrusion rod 18 downward. At this time, the extrusion rod 18 slides downward inside the extrusion head 17 and the fitting spring 33 contracts and deforms, allowing the downward movement operation to be unobstructed.

[0031] The reciprocating pushing member includes a push seat 9 slidably mounted through the upper end near the edge of the treatment box 1. A connecting seat 10 is fixedly mounted at the lower end of the push seat 9. The connecting seat 10 serves as a connection. A plurality of push frames 11 are fixedly mounted in a linear array at the lower end of the connecting seat 10. The extrusion rod 18 and the extending frame 21 are respectively fixed to both ends of the push frame 11. The push frame 11 serves to carry the extrusion rod 18 and the extending frame 21. The push seat 9 serves to drive the extrusion rod 18 and the extending frame 21 to move up and down. A second bearing shaft 15 is rotatably mounted at the front upper edge of the treatment box 1. A swing frame 39 is fixedly mounted at the end of the second bearing shaft 15. A connecting rod 8 is rotatably mounted at the end of the swing frame 39. The end of the connecting rod 8 is rotatably connected to the push seat 9. When the second bearing shaft 15 rotates, it can drive the swing frame 39 to rotate, and then drive the connecting rod 8 to move, causing the push seat 9 to continuously move up and down reciprocally.

[0032] The flow-pushing member includes a plate shaft 13 rotatably installed inside the processing tank 1 near the L-shaped shell 16. The plate shaft 13 penetrates through the front end of the processing tank 1. A plurality of flow-pushing plates 14 are arranged in an annular array on the outer surface of the plate shaft 13. The plate shaft 13 serves to carry the flow-pushing plates 14. When the servo motor 5 drives the second bearing shaft 15 to rotate, it will also drive the large gear 37 on the first bearing shaft 6 to rotate, and then drive the small gear 38 to rotate rapidly, so that the flow-pushing plates 14 on the plate shaft 13 push the processing liquid at the side end of the L-shaped shell 16 to make it flow, enabling the processing liquid in the processing tank 1 to flow to the L-shaped shell 16 and enter the inside of the L-shaped shell 16, thereby ensuring that the processing liquid in the processing tank 1 is fully utilized.

[0033] The first bearing shaft 6 is rotatably installed above the plate shaft 13 at the front end of the processing tank 1. The first bearing shaft 6 serves as a transmission. The front end of the first bearing shaft 6 is coaxially inlaid with a large gear 37, and the front end of the plate shaft 13 is coaxially inlaid with a small gear 38. The large gear 37 meshes with the small gear 38. The large gear 37 and the small gear 38 serve to accelerate the rotation of the plate shaft 13. The servo motor 5 is fixedly installed above the front end of the processing tank 1 away from the first bearing shaft 6. The output end of the servo motor 5, the outer surface of the second bearing shaft 15, and the outer surface of the first bearing shaft 6 are all coaxially inlaid with pulleys 36. A belt 7 is connected between the three pulleys 36. The pulleys 36 and the belt 7 serve to make the second bearing shaft 15 and the first bearing shaft 6 rotate synchronously.

[0034] During processing, the chemical industry flue gas enters the inner vertical section of multiple L-shaped shells 16 through the intake pipe 2. Subsequently, the servo motor 5 operates to drive the swing frame 39 on the second bearing shaft 15 to rotate, thereby driving the connecting rod 8 to move, causing the push seat 9 to continuously reciprocate up and down. When the push seat 9 moves downward, the extrusion rod 18 and the extension frame 21 will be driven to move downward synchronously. At this time, the downward-moving extrusion rod 18 will push the extrusion head 17, so as to push the chemical industry flue gas located in the inner vertical section of the L-shaped shell 16 downward through the extrusion head 17, and make it be extruded into the treatment liquid in the inner horizontal section of the L-shaped shell 16. When the extrusion of the extrusion head 17 is completed, the positioning ear 19 just abuts against the positioning seat 20, so that the extrusion head 17 will not continue to move. At the same time, the pressure ear 22 on the extension frame 21 presses on the push cap seat 41. Subsequently, the push seat 9 continues to drive the extrusion rod 18 and the extension frame 21 to move downward. At this time, the extrusion rod 18 slides downward in the extrusion head 17 and adapts to the contraction deformation of the spring 33, so that the downward movement operation will not be hindered. The downward-moving extension frame 21 will press on the push cap seat 41 through the pressure ear 22, causing it to move downward, thereby driving the inclined frame 40 to move, so as to push the cap rod 31, making the discharge cap 30 on the cap rod 31 able to slide in the inner horizontal section of the L-shaped shell 16. At the same time, the moving cap rod 31 will also drive the hook frame 25 to move, causing the hook frame 25 to move sideways, so as to loosen the pulling on the hook ear 27, allowing the opening spring 35 to gradually recover its deformation, so as to push open the sealing cover 29 and open the side end of the L-shaped shell 16, so that during the sliding process of the discharge cap 30, the treatment liquid dissolved with the chemical industry flue gas can be pushed out. Subsequently, the push seat 9 moves upward. At this time, the extrusion rod 18 slides upward in the extrusion head 17 and adapts to the gradual recovery of the spring deformation of the spring 33. When the convex block 32 slides to the top of the extrusion head 17, the extrusion rod 18 will use the convex block 32 to lift the extrusion head 17, so that the extrusion head 17 moves upward to reset, allowing the chemical industry flue gas in the intake pipe 2 to enter the inner vertical section of the L-shaped shell 16. At the same time, when the extension frame 21 moves upward, the top ear 23 on it will abut against the lower end of the push cap seat 41 to lift the push cap seat 41, so that the discharge cap 30 slides back to its original position. During the reset process, the treatment liquid around the side end of the L-shaped shell 16 will enter the inner horizontal section of the L-shaped shell 16 again. When the discharge cap 30 is completely reset, the end of the hook frame 25 will pull on the hook ear 27 again, so that the sealing cover 29 is pressed on the L-shaped shell 16 for sealing. This cycle is repeated to continuously squeeze the chemical industry flue gas, so that it can be quickly dissolved in the treatment liquid, allowing the chemical industry flue gas and the treatment liquid to fully contact, so that the harmful gases in the chemical industry flue gas can be fully absorbed and removed by the treatment liquid. The treated chemical industry flue gas is discharged from the outlet pipe 3.
