Description

Technical Field

[0001] This invention relates to the field of exhaust gas treatment in glass processing, and in particular to a purification device and process for exhaust gas treatment in glass processing. Background Technology

[0002] The glass processing process generates dust (silicon powder, glass microspheres) and acidic gases (SO2, NO). x For pollutants such as HF and small amounts of VOCs, exhaust gas purification requires a graded treatment + combined process equipment scheme based on the type and concentration of pollutants.

[0003] Existing glass processing exhaust gas treatment typically includes dust removal via baghouse dust collectors. Depending on the specific glass processing steps and the different pollutants and gases generated, additional desulfurization, denitrification, and neutralization processes are also implemented. However, in basic baghouse dust collection systems, the throughput decreases over long-term use, thus reducing the effectiveness and efficiency of exhaust gas treatment in glass processing. Therefore, this paper proposes a purification device and process for exhaust gas treatment in glass processing. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a purification device and process for treating exhaust gas from glass processing. This device can flexibly and modularly integrate multiple treatment processes and perform timely and effective cleaning of basic bag filters, thereby improving the efficiency and effectiveness of treating and purifying exhaust gas from glass processing.

[0007] Preferably, the angle adjustment assembly includes a limiting slide box and a ratchet. The limiting slide box is symmetrically slidably arranged on both the front and rear sides of each sleeve and is located on the front and rear sides of the ratchet. The limiting slide box is connected to the connecting plate. One end of the ratchet slides inside the limiting slide box and the other end extends to the outside of the limiting slide box and engages with the ratchet.

Each slide opening is located between two adjacent frames. The slide block slides in the corresponding slide opening and extends through the slide opening into the frame. The extension end in the frame is connected to the connecting plate. The two ends of the connecting plate are respectively connected to the adjacent limiting slide boxes on both sides.

[0009] Preferably, the outer side of the guide rod frame is fitted with multiple limiting seats, each of which corresponds to a slide seat. A spring three fitted on the outer side of the guide rod frame is connected between the slide seat and the limiting seat. The ratchet teeth in the limiting slide box one on the front and rear sides of the ratchet are opposite in direction and cooperate to engage the front and rear sides of the ratchet. The left and right sides of the sleeve frame are also connected to the limiting slide box two. A ratchet block is slidably fitted in the limiting slide box two, and one end of the ratchet block extends to the outside of the limiting slide box two to engage with the ratchet and cooperate with the ratchet to limit the ratchet in one direction.

[0010] Preferably, the drive assembly includes a vertical plate, a rotating plate, and an L-shaped limiting seat. The vertical plate is connected to the lower end of each slide. The rotating plate is rotatably connected to the lower end of the vertical plate via a spring hinge and is at a certain angle to the vertical plate. The L-shaped limiting seat is connected to the lower inner wall of the chassis and is located at the lower end of each corresponding rotating plate. The lower end of the rotating plate also engages with the L-shaped limiting seat.

[0011] Preferably, a limiting block is connected to the side of the vertical plate away from the L-shaped limiting seat, the first rotating plate is tilted and limited by the limiting block, the first rotating plate on the front and rear sides of the frame is tilted in opposite directions, and the corresponding L-shaped limiting seats are also arranged in opposite positions.

[0012] Preferably, the clutch assembly includes a lever and a trapezoidal block. The lever is connected to both sides of the slide plate, and the trapezoidal block is connected to the front and rear inner walls of the chassis. The upper and lower symmetrical inclined surfaces of the trapezoidal block are both in contact with and slide against the lever.

[0013] Preferably, both sides of the frame are connected to slide rod frames, and the slide plate is slidably sleeved on the outside of the slide rod frame on each side. A limiting ring is sleeved on the outside of the slide rod frame to limit the slide plate. A spring four sleeved on the outside of the slide rod frame is connected between the side of the slide plate away from the limiting ring and the end of the slide rod frame. A limiting frame is connected to the side of the slide plate close to the frame, and the lower end face of the rotating plate is horizontally limited by the limiting frame.

[0014] A purification method for exhaust gas treatment based on glass processing includes the following steps: Step 1: The exhaust gas from glass processing is sent into the chassis through the air inlet, and the exhaust gas is placed in the chassis below the liner. The exhaust gas is filtered and purified by multiple membrane dust collection bags installed in the chassis, and then discharged through the internal space of the chassis above the liner and the exhaust port. Step 2: After continuous dust removal of glass processing exhaust gas, excessive dust will gradually accumulate on the outside of the coated dust collector bag, affecting its passability. Control the telescopic component to move the frame up and down, so as to drive the brushes arranged in array in each rotating ring to clean the outside of the coated dust collector bag. Step 3: When the frame moves to the bottom of the chassis, the drive component will drive the connecting plate to slide, and then drive the angle adjustment component to slide in opposite directions through the front and rear connecting plates. This will drive the ratchet and the rotating ring to rotate slightly on one side. The rotation angle does not exceed the circumference angle of the brush itself. This process is repeated to control the frame up and down, so that the outside of the film-coated dust collection bag can be thoroughly cleaned by continuously adjusting the angle and sliding the brush up and down, thus achieving automated cleaning. Step 4: When the frame is moved to the bottom, the second rotating plate will rotate to the bottom of the lever plate. As the frame moves upward, it will push the supporting lever plate and the bottom frame upward until they engage with the clutch assembly. This will release the support of the lever plate, allowing it to move downward under gravity. During this process, the coated dust collector bag will be compressed first and then unfolded and tightened, further shaking off the dust accumulated on the surface of the coated dust collector bag, thus improving the efficiency and effect of purifying glass processing exhaust gas.

[0015] The beneficial effects of this invention are: 1. The technical solution of the present invention introduces glass processing exhaust gas into the space below the inner lining plate of the chassis through the air inlet, and filters it through multiple membrane dust collection bags. Then, it is discharged from the space above the inner lining plate of the chassis and the exhaust port. During the process, when the membrane dust collection bags filter the glass processing exhaust gas for a long time, a lot of dust and other particulate matter will accumulate on their surface, reducing the passivity of the membrane dust collection bags. In this way, the telescopic component can be controlled to move up and down to drive the frame and sleeve frame to move up and down, so that the rotating ring of the sleeve frame and the multiple brushes connected to the inner wall of the rotating ring can move up and down to clean the surface of the membrane dust collection bag, thereby improving the effect and efficiency of the membrane dust collection bag in continuously purifying the glass processing exhaust gas. 2. The technical solution of this invention involves the following: When the frame moves down to the bottom of the chassis, the rotating plates below the sliding blocks slidably mounted on the guide rods on both sides will engage with their respective L-shaped limiting seats, causing the front and rear sliding blocks of the frame to slide in opposite directions. Consequently, the connecting plates on the front and rear sides of the frame and the limiting sliding boxes will move in opposite directions, allowing the ratchet slidably mounted inside the limiting sliding box to engage with the ratchet. Through the engagement of the front and rear ratchets with the ratchet, the ratchet is driven to rotate, thereby adjusting the brushes connected to the inner wall array of the rotating ring to rotate. The rotation angle is less than the angle of the brush itself. When the frame moves up, each rotating plate will gradually disengage from the L-shaped limiting seats, and the spring... Under the action of spring three, the limiting slide box one and the ratchet are driven to slide back until they are limited by the limiting seat. During the process, the front and rear ratchet will abut against the ratchet and slide inward into the limiting slide box one. At the same time, spring two is compressed, and the ratchet block in the limiting slide box two limits the ratchet, so that the ratchet does not rotate. Thus, the ratchet can only rotate in one direction, so as to adjust each brush to rotate at a certain angle and slide up and down in turn, so as to clean the coated dust collector bag repeatedly and thoroughly. At the same time, the coated dust collector bag can be backflushed by the backflushing module, and the dust and other particles in the machine box can be comprehensively collected by the cyclone separator, improving the cleaning effect of the coated dust collector bag. 3. The technical solution of the present invention, by moving the frame downward, allows the second rotating plate to abut against the upper end of the dial plate and overcome the elasticity of the spring hinge, rotating to the lower side of the dial plate. Then, when the frame moves upward, it can support the dial plate and the bottom frame to move upward, and drive each coated dust collector bag to retract upward until the levers on both sides of the slide plate abut against the lower inclined surface of the trapezoidal block and slide away from the frame. This allows the second rotating plate, which is horizontally limited, to be pulled away from under the dial plate. Under the action of the first spring and gravity, the bottom frame falls and tightens the retracted coated dust collector bags, shaking off the dust on the surface of the coated dust collector bags, further improving the cleaning effect of the coated dust collector bags, and making the purification effect of glass processing exhaust gas better.

[0018] The following will be combined with the appendix Figure 1 To be continued Figure 10 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: As Figures 1-10 As shown, this invention discloses a purification device for exhaust gas treatment based on glass processing, including a casing 1. An air inlet 2 and an air outlet 3 are respectively provided on the front and rear sides of the casing 1. A horizontal liner 8 is installed on the inner wall of the casing 1, and multiple sleeves 9 are threaded through the liner 8. A membrane-coated dust collector bag 10 is fitted onto the lower end of each sleeve 9. A bottom frame 12 is slidably provided at the lower end of the casing 1, and the bottom frame 12 is connected to the lower end of each membrane-coated dust collector bag 10. The bottom frame 12 is connected to two ends of a lever plate 14. Multiple telescopic parts 15 are installed on the lower inner wall of the chassis 1. The upper ends of each telescopic part 15 are connected to a frame 16. Each coated dust collector bag 10 is fitted with a sleeve frame 17 connected to the inner wall of the frame 16. A rotating ring 18 is rotatably fitted on the inner wall of the sleeve frame 17. A ratchet 19 is fitted on the outer side of the rotating ring 18. A brush 23 that fits against the outer side of the coated dust collector bag 10 is arrayed on the inner wall of the rotating ring 18. Guide rod frames 26 are connected to both the front and rear sides of the frame 16. Slide seats 29 are slidably arranged between adjacent sleeve frames 17, and slide seats 29 are slidably sleeved on the surface of guide rod frames 26. Connecting plates 28 are connected to slide seats 29. An angle adjustment component is provided on connecting plates 28. The angle adjustment component is used to engage ratchet 19 in one direction when slide seat 29 slides, so as to drive ratchet 19, rotating ring 18 and brush 23 to rotate in one direction. A drive component is also provided on slide seat 29. The drive component is used to drive slide seat 29 to slide. Slide plates 40 are symmetrically slidably arranged at both ends of the frame 16. A second rotating plate 43 is rotatably connected to slide plate 40. The second rotating plate 43 supports the lower end face of the lever plate 14 to lift the bottom frame 12 upward. A clutch component is also provided on slide plate 40. The clutch component is used to lift the lever plate 14 and the bottom frame 12 upward when the frame 16 moves upward, and then separate from the bottom frame 12 so that the bottom frame 12 falls and slides.

[0020] The front end of the chassis 1 is connected to the exhaust gas cooling box 6 through the air inlet 2, and the rear end of the chassis 1 is connected to the SCR reaction box 7 through the exhaust port 3. The upper end of the chassis 1 is equipped with a back-blowing module 4, and the lower end of the chassis 1 is also equipped with a cyclone separator 5. The lower end face of the chassis 1 is connected to a step rod 11. The bottom frame 12 is slidably sleeved on the outside of the step rod 11, and a spring 13 sleeved on the outside of the step rod 11 is connected between the upper end of the bottom frame 12 and the upper end of the step rod 11. A sliding groove 21 is opened on the frame 17, and a slider 22 that slides in the sliding groove 21 is connected to the limiting sliding box 20.

[0021] Among them, the air inlet 2 and the air outlet 3 can not only be connected to the exhaust gas cooling box 6 and the SCR reaction box 7, but also other treatment equipment or modules can be flexibly and modularly selected according to the properties of the glass processing exhaust gas. The back-blowing module 4 can back-blow from the inside of the membrane dust collector bag 10 to the outside, sweeping away the dust and other particles in the glass processing exhaust gas filtered and accumulated on the outer surface of the membrane dust collector bag 10, and then collect and separate them through the cyclone separator 5.

[0022] Example 2: Figures 1-10 As shown, the present invention discloses a purification device for exhaust gas treatment based on glass processing. Compared with Embodiment 1, this embodiment discloses the structure of the angle adjustment component.

[0023] The angle adjustment assembly includes a limiting slide box 20 and a ratchet 24. The limiting slide box 20 is symmetrically slidably arranged on both the front and rear sides of each sleeve 17 and is located on the front and rear sides of the ratchet 19. The limiting slide box 20 is connected to the connecting plate 28. One end of the ratchet 24 slides inside the limiting slide box 20, and the other end extends to the outside of the limiting slide box 20 and engages with the ratchet 19. Multiple springs 25 are connected at equal intervals between the end of the ratchet 24 inside the limiting slide box 20 and the inner wall of the limiting slide box 20.

[0024] When the sliding block 29 on the guide rod bracket 26 slides and drives the limiting sliding box 20 and the ratchet 24 to slide, and at the same time the front and rear limiting sliding boxes 20 and the ratchet 24 slide in opposite directions, the ratchet 24 can be engaged with the ratchet 19, causing the ratchet 19 to rotate, and causing the multiple brushes 23 arrayed on the inner wall of the rotating ring 18 to rotate at a certain angle, and the rotation angle is less than the angle of the brush 23 itself. When the front and rear limiting sliding boxes 20 and the ratchet 24 slide back to their original positions under the action of their respective springs 31, the ratchet 24... 4 will contact the ratchet 19 and slide into the limiting slide box 20, while compressing the spring 25, so that the ratchet 19 does not rotate, thus realizing that the ratchet 19 can only rotate in one direction, so that the moving angle of each brush 23 can be adjusted in one direction each time. In conjunction with the frame 16 and the sleeve 17 being driven up and down by the telescopic part 15, the surface of the coated dust collector bag 10 is thoroughly cleaned, thereby improving the cleaning effect of the coated dust collector bag 10, preventing dust particles in the glass processing exhaust gas from accumulating on its surface and causing blockage, and improving its passability.

[0025] The frame 16 has slide openings 27 on both the front and rear sides, and the slide openings 27 penetrate the inside and outside of the frame 16. Each slide opening 27 is located between two adjacent frames 17. The slide seat 29 slides in the corresponding slide opening 27 and extends through the slide opening 27 into the frame 16. The extension end inside the frame 16 is connected to the connecting plate 28. The two ends of the connecting plate 28 are respectively connected to the adjacent limiting slide boxes 20 on both sides, so that the limiting slide boxes 20 can slide stably along the guide rod frame 26 and the slide opening 27 on both sides of the frame 16 with the slide seat 29 and the connecting plate 28.

[0026] Multiple limiting seats 30 are fitted on the outer side of the guide rod frame 26. Each limiting seat 30 corresponds to the slide 29. A spring 31 fitted on the outer side of the guide rod frame 26 connects the slide 29 and the limiting seat 30. The ratchet 24 in the limiting slide box 1 20 on the front and rear sides of the ratchet 19 has opposite teeth and engages with the front and rear sides of the ratchet 19. The left and right sides of the sleeve frame 17 are also connected to the limiting slide box 2 36. A ratchet block 37 is slidably fitted in the limiting slide box 2 36. One end of the ratchet block 37 extends to the outside of the limiting slide box 2 36 and engages with the ratchet 19, and cooperates with the ratchet 24 to limit the ratchet 19 in one direction.

[0027] This ensures that each slide block 29 has the same sliding stroke under the limiting position of the limiting seat 30 and the limiting position of the spring 31. At the same time, the ratchet block 37 in the limiting slide box 26 can be compressed back into the limiting slide box 10 when the ratchet 24 drives the ratchet 19 to rotate. When the limiting slide box 10 and the ratchet 24 return to their original sliding position, the ratchet block 37 can remain stable and not rotate by meshing with the ratchet 19, thereby improving the stability and accuracy of angle adjustment.

[0028] Example 3: Figures 1-10 As shown, the present invention discloses a purification device for exhaust gas treatment based on glass processing. Compared with Embodiment 2, this embodiment discloses the structure of the drive component.

[0029] The drive assembly includes a vertical plate 32, a rotating plate 33, and an L-shaped limiting seat 35. The vertical plate 32 is connected to the lower end of each slide 29. The rotating plate 33 is rotatably connected to the lower end of the vertical plate 32 via a spring hinge and is at a certain angle to the vertical plate 32. The L-shaped limiting seat 35 is connected to the lower inner wall of the chassis 1 and is located at the lower end of each corresponding rotating plate 33. The lower end of the rotating plate 33 also engages with and abuts against the L-shaped limiting seat 35.

[0030] When the frame 16 moves down to the bottom of the chassis 1, the rotating plate 33 below the slide block 29 slidably mounted on the guide rod frame 26 on both sides will engage with the corresponding L-shaped limit seat 35 and drive the front and rear slide blocks 29 of the frame 16 to slide in opposite directions.

[0031] The side of the vertical plate 32 away from the L-shaped limiting seat 35 is connected to the limiting block 34. The rotating plate 33 is tilted and limited by the limiting block 34. The rotating plates 33 on the front and rear sides of the frame 16 are tilted in opposite directions, and the corresponding L-shaped limiting seats 35 are also arranged in opposite positions. This ensures that the rotating plate 33 is tilted to stably cooperate with the L-shaped limiting seat 35 and push the slide 29 to slide on its respective guide rod frame 26.

[0032] Example 4: Figures 1-10 As shown, the present invention discloses a purification device for exhaust gas treatment based on glass processing. Compared with Embodiment 3, this embodiment discloses the structure of the clutch assembly.

[0033] The clutch assembly includes a lever 44 and a trapezoidal block 45. The lever 44 is connected to both sides of the slide plate 40, and the trapezoidal block 45 is connected to the front and rear inner walls of the chassis 1. The upper and lower symmetrical inclined surfaces of the trapezoidal block 45 are in contact with and slide against the lever 44.

[0034] Both sides of the frame 16 are connected to slide rod brackets 38. The slide plate 40 is slidably sleeved on the outside of the slide rod bracket 38 on each side. The outside of the slide rod bracket 38 is fitted with a limiting ring 39 to limit the slide plate 40. The side of the slide plate 40 away from the limiting ring 39 is connected to the end of the slide rod bracket 38 by a spring 41 sleeved on the outside of the slide rod bracket 38. The side of the slide plate 40 close to the frame 16 is connected to a limiting frame 42. The lower end face of the rotating plate 43 is horizontally limited by the limiting frame 42.

[0035] This allows the rotating plate 43 to contact the upper end of the lever plate 14 during the downward movement of the frame 16, overcoming the elasticity of the spring hinge and rotating to the lower side of the lever plate 14. Then, when the frame 16 moves upward, it can support the lever plate 14 and the bottom frame 12 to move upward, and drive each coated dust collector bag 10 to retract upward until the levers 44 on both sides of the slide plate 40 contact the lower inclined surface of the trapezoidal block 45 and slide away from the frame 16. This allows the rotating plate 43, which is horizontally limited by the limiting frame 42, to be pulled away from under the lever plate 14. Under the action of the spring 13 and gravity, the bottom frame 12 falls and tightens the retracted coated dust collector bags 10, shaking off the dust on the surface of the coated dust collector bags 10, further improving the cleaning effect of the coated dust collector bags 10, and making the purification effect of glass processing exhaust gas better.

[0036] Example 5: Figures 1-10 As shown, this invention discloses a purification method for exhaust gas treatment based on glass processing, comprising the following steps: Step 1: The glass processing exhaust gas is sent into the housing 1 through the air inlet 2, and the exhaust gas is located in the housing 1 below the liner plate 8. The glass processing exhaust gas is filtered and purified by multiple membrane dust collection bags 10 installed in the housing 1, and then discharged through the internal space of the housing 1 above the liner plate 8 and the exhaust port 3. Step 2: After continuous dust removal of glass processing exhaust gas, too much dust will gradually accumulate on the outside of the coated dust collector bag 10, affecting its passability. Control the telescopic component 15 to drive the frame 16 to move up and down, so as to drive the brushes 23 arranged in array in each rotating ring 18 to clean the outside of the coated dust collector bag 10. Step 3: When the frame 16 moves to the bottom of the chassis 1, the drive component will drive the connecting plate 28 to slide, and then drive the angle adjustment component to slide in opposite directions through the front and rear connecting plates 28, causing the ratchet 19 and the rotating ring 18 to rotate slightly on one side. The rotation angle does not exceed the circumference angle of the brush 23 itself. In this way, the frame 16 is controlled up and down repeatedly, so that the brush 23 can continuously adjust the angle and slide up and down to clean the outside of the film-coated dust collection bag 10, and perform automated cleaning. Step 4: When the frame 16 is moved to the bottom, the rotating plate 2 43 will rotate to the bottom of the lever plate 14. When the frame 16 moves upward, it will push the supporting lever plate 14 and the bottom frame 12 upward until they engage with the clutch assembly. This will cancel the support of the lever plate 14, allowing it to move downward under gravity. During this process, the coated dust collector bag 10 will be compressed first and then unfolded and tightened, further shaking off the dust accumulated on the surface of the coated dust collector bag 10, thereby improving the efficiency and effect of purifying glass processing exhaust gas.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention.

10. A purification method for exhaust gas treatment based on glass processing, comprising a purification device for exhaust gas treatment based on glass processing as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: The glass processing exhaust gas is sent into the chassis (1) through the air inlet (2), and the exhaust gas is located in the chassis (1) below the liner (8). The glass processing exhaust gas is filtered and purified by multiple membrane dust collection bags (10) installed in the chassis (1), and then discharged through the internal space of the chassis (1) above the liner (8) and the exhaust port (3). Step 2: After continuous dust removal of glass processing exhaust gas, too much dust will gradually accumulate on the outside of the coated dust collector bag (10), affecting its passability. Control the telescopic component (15) to drive the frame (16) to move up and down, so as to drive the brushes (23) arranged in array in each rotating ring (18) to clean the outside of the coated dust collector bag (10). Step 3: When the frame (16) moves to the bottom of the chassis (1), the drive component will drive the connecting plate (28) to slide, and then drive the angle adjustment component to slide in opposite directions through the front and rear connecting plates (28), causing the ratchet (19) and the rotating ring (18) to rotate slightly on one side. The rotation angle does not exceed the circumference angle of the brush (23) itself. In this way, the frame (16) is controlled up and down repeatedly, so that the angle is continuously adjusted and the brush (23) slides up and down to clean the outside of the film dust removal bag (10) and perform automated cleaning. Step 4: When the frame (16) is moved to the bottom, the second rotating plate (43) will rotate to the bottom of the lever plate (14), and when the frame (16) moves up, it will push the supporting lever plate (14) and the bottom frame (12) to move up until they cooperate with the clutch assembly, canceling the support of the lever plate (14), so that it moves down under the action of gravity, and in the process, the coated dust collector bag (10) is compressed first, and then unfolded and tightened, further shaking off the dust accumulated on the surface of the coated dust collector bag (10), improving the efficiency and effect of purifying glass processing exhaust gas.
