Description

An industrial waste gas dust treatment device Technical Field

[0001] This invention relates to the field of waste gas and dust treatment technology, specifically an industrial waste gas and dust treatment device. Background Technology

[0002] Industrial waste gas refers to the mixed gases emitted into the atmospheric environment during industrial production processes due to various technological operations. It includes gaseous emissions such as sulfur dioxide and nitrogen oxides produced during chemical industry production, which are corrosive and highly polluting and have a negative impact on atmospheric environmental quality.

[0003] Industrial waste gas contains a large amount of dust. Dust refers to solid particles in the atmosphere with a diameter of 1-100 micrometers. In a broader sense, dust also includes suspended particulate matter and settling dust. It mainly comes from coal combustion and the production processes of certain industries (such as cement). Industrial dust is a significant air pollutant that is very harmful to the respiratory system and eyes. Therefore, it is necessary to use treatment devices to treat waste gas dust to ensure that the waste gas meets the emission standards and reduce air pollution.

[0004] However, existing industrial waste gas dust treatment devices typically use filter bags as the core filtration unit. As the filtration time increases during operation, dust gradually accumulates on the surface of the filter bags, leading to increased filtration resistance. This necessitates timely replacement of the filter bags, which is cumbersome and consequently affects the efficiency of waste gas treatment. Summary of the Invention

[0014] Preferably, a connecting pipe is fixedly connected between the processing cylinder and the processing box. One side of the first filter plate faces the side of the connecting pipe.

[0015] Preferably, a sealing plate is slidably provided on one side of the intake pipe, the sealing plate is located inside the intake pipe, a support plate is fixedly connected to the upper side of the sealing cover, an electric push rod is fixedly connected to one side of the support plate, and the telescopic end of the electric push rod is fastened to the sealing plate.

[0016] The beneficial effects of this invention are as follows: 1. This invention uses water at the bottom of the treatment cylinder and a rotatable circular plate to support multiple filter bags. The first servo motor drives the circular plate to rotate, achieving automatic filter bag switching. When a single filter bag is saturated, the controller controls the first servo motor to drive the circular plate to rotate, so that a new filter bag is aligned with the air inlet pipe to continue working, greatly reducing the frequency of filter bag replacement. When all filter bags have been used, the electric push rod drives the sealing plate to close the air inlet pipe, and the second servo motor drives the bristle brush to move along the surface of the filter bag to brush off the attached dust. The dust falls into the water at the bottom of the cylinder and is effectively captured, achieving filter bag cleaning. The dual measures of filter bag switching and filter bag cleaning greatly extend the continuous operation time of the waste gas treatment and significantly improve the working efficiency of waste gas treatment.

[0017] 2. The present invention features an array of first filter plates, which are sequentially rotated and replaced by a third servo motor via bevel gear transmission. This ensures that each filter plate continuously switches to the direction of the connecting pipe for filtration, preventing a single filter plate from reducing its filtration effect due to dust accumulation. Subsequently, the third servo motor synchronously drives the first gear to rotate, which in turn drives the double-headed plate and rollers to reciprocate up and down via the first rack. The rollers press or release the lower inclined plate, causing the elastic slider to move relative to or towards the round rod, thereby achieving reciprocating adjustment of the distance between the two spraying devices. This ensures that the water mist evenly covers the inside of the treatment box, eliminating localized treatment dead zones. At the same time, the adjustment of the spraying device distance and the rotation and replacement of the first filter plates are synchronously driven by the same motor, reducing costs and significantly improving the uniformity of waste gas treatment.

[0018] 3. When the industrial waste gas treatment is completed, the drive device moves the lifting frame and sealing cover upwards, and the arrayed filter bags rise to a higher position, making it easy for operators to quickly replace the filter bags and ensure the subsequent treatment effect. When the sealing cover moves upwards, the first rotating shaft drives the stop block and sealing ring to rise synchronously, automatically opening the first circular groove, so that the polluted water in the treatment cylinder is discharged into the storage tank through the pipe. At the same time, the water generated during the spraying process is filtered by the second filter plate and also flows into the storage tank, realizing centralized collection of sewage, which is convenient for subsequent centralized treatment, and there is no need to open the drainage mechanism separately, saving time and effort.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please refer to Figures 1-11. This invention is an industrial waste gas dust treatment device, including a treatment device body 1. A top frame 2 is fixedly connected to the upper side of the treatment device body 1. A treatment cylinder 3 and a treatment box 4 for treating waste gas dust are fixedly connected to the upper side of the top frame 2. A sealing cover 5 is snapped onto the upper side of the treatment cylinder 3. A rubber gasket is fixedly provided on the outer surface of the sealing cover 5. When the sealing cover 5 moves down, it can snap and seal into the treatment cylinder 3, so that the sealing cover 5 and the rubber gasket can seal the entire treatment cylinder 3, ensuring that industrial waste gas will not leak. The lower side of the sealing cover 5 is rotatably connected to... There is a first rotating shaft 6, and a circular plate 7 is fixedly connected to the outer surface of the first rotating shaft 6. The upper side of the circular plate 7 has an array of grooves 8. A filter bag 9 is fixedly connected inside the grooves 8. A drive box is fixedly connected to the lower side of the circular plate 7. A collar frame 40 is fitted on the outer surface of the filter bag 9. A bristle soft brush 41 is fixedly installed inside the collar frame 40. The drive box is used for the bristle soft brush 41 to clean the outside of the filter bag 9. The bristle soft brush 41 can effectively clean the dust, while protecting the fiber structure of the filter bag 9 to the maximum extent. A reciprocating spraying mechanism is fixedly installed at the top of the inside of the treatment box 4.

[0024] It can be explained that each time the first servo motor 52 is started, the output shaft of the first servo motor 52 rotates the first rotating shaft 6 to complete one rotation path, so that the next groove 8 on the circular plate 7 can be connected to the bottom of the air inlet pipe 10, so that the air inlet pipe 10 and the groove 8 can be connected, allowing all the industrial waste gas to enter the filter bag 9, ensuring the filtration effect of the filter bag 9. At this time, the waste gas remaining during the replacement of the filter bag 9 is still inside the treatment cylinder 3, and the subsequent spraying mechanism uses water mist to allow the dust in the waste gas to settle naturally.

[0025] An air inlet pipe 10 communicating with the sealing cover 5 is fixedly connected to the upper side of the sealing cover 5. The air inlet pipe 10 corresponds one-to-one with the groove 8. The drive box includes a U-shaped box 36 fixedly connected to the bottom of the circular plate 7. A second rack 39 is provided on the side of the U-shaped box 36 near the outside. A fifth rotating shaft 37 is rotatably connected to one side of the U-shaped box 36. A fourth gear 38 meshing with the second rack 39 is fixedly connected to the outer surface of the fifth rotating shaft 37. One side of the second rack 39 is fastened to the collar frame 40. A second servo motor 53 is fixedly connected to one side of the U-shaped box 36. The output shaft of the second servo motor 53 is fastened to the fifth rotating shaft 37.

[0026] It can be explained that when the injection of industrial waste gas into the treatment cylinder 3 stops, the forward and reverse rotation of the second servo motor 53 will drive the fourth gear 38 on the fifth rotating shaft 37 to rotate. At this time, the U-shaped box 36 can limit and guide the movement trajectory of the second rack 39, allowing the second rack 39 to move up and down, so as to drive each set of bristle soft brushes 41 in the collar frame 40 to clean the filter bag 9 smoothly and safely. At the same time, the collar frame 40 surrounds the outer surface of the filter bag 9 to ensure that the bristle soft brushes 41 clean the outer surface of the filter bag 9.

[0027] The upper side of the first rotating shaft 6 passes through the sealing cover 5 and extends to the upper side of the sealing cover 5. The upper side of the first rotating shaft 6 is fixedly connected to the second gear 31. The upper side of the sealing cover 5 is fixedly connected to the L-shaped plate 32. The fourth rotating shaft 33 is rotatably connected to one side of the L-shaped plate 32. The lower side of the fourth rotating shaft 33 is fixedly connected to the third gear 34 that meshes with the second gear 31. The other side of the L-shaped plate 32 is fixedly connected to the first servo motor 52. The output shaft of the first servo motor 52 is fastened to the fourth rotating shaft 33.

[0028] A sealing box 12 is fixedly connected inside the processing box 4. A third rotating shaft 13 is rotatably connected to the lower side of the sealing box 12. An array of mounting plates 15 are connected to the outer surface of the third rotating shaft 13. A first filter plate 16 is fixedly connected to one side of the mounting plate 15. A second rotating shaft 11 is rotatably connected to one side of the inside of the processing box 4. One side of the second rotating shaft 11 passes through the sealing box 12 and extends into the interior of the sealing box 12. The upper side of the third rotating shaft 13 passes through the sealing box 12 and extends into the interior of the sealing box 12. Bevel gears 14 are fixedly connected to one side of the second rotating shaft 11 and the upper side of the third rotating shaft 13. The two bevel gears 14 mesh with each other. A third servo motor 54 is fixedly connected to one side of the processing box 4. The output shaft of the third servo motor 54 is fastened to the second rotating shaft 11.

[0029] The spraying mechanism includes two round rods 17 fixedly connected inside the treatment box 4. Two symmetrically arranged sliders 18 are slidably connected to the outer surfaces of the two round rods 17. Spraying devices 19 are fixedly connected to the lower sides of each slider 18. Two first springs 20 are fixedly connected between the two sliders 18. A first gear 21 is fixedly connected to the outer surface of the second rotating shaft 11. A guide plate 22 is fixedly connected to one side inside the treatment box 4. A first rack 23, meshing with the first gear 21, is slidably connected to the guide plate 22. A mounting bracket 24 is fixedly connected to the upper side of the first rack 23. A double-headed plate 26 is fixedly connected to the lower side of the mounting bracket 24. Two symmetrically arranged rollers 27 are rotatably connected to the lower side of the double-headed plate 26. The inner sides of the two sliders 18 are fixedly connected to... A lower inclined plate 25 is connected, and rollers 27 are attached to the upper side of the lower inclined plate 25. Through the installation and use of guide plate 22 and first rack 23, the first rack 23 can move up and down on guide plate 22. In this way, guide plate 22 can limit the movement trajectory of the first rack 23, ensuring that the first rack 23 rises and falls smoothly and reliably, so as to realize the reciprocating movement of the spraying mechanism, ensuring that water mist can evenly cover the inside of the treatment box 4, improving the treatment effect of industrial waste gas. With the synergistic effect of filter bag 9, first filter plate 16 and spraying device 19, it is conducive to realizing the continuous and efficient treatment of industrial waste gas dust. At the same time, after subsequent testing of waste gas, it is ensured that it meets emission standards, so that it can be safely discharged and reduce pollution to the atmosphere.

[0030] A water pump 28 is fixedly connected to the upper side of the treatment box 4, and a water tank is fixedly connected to the upper side of the treatment device body 1. The water tank and the water pump 28 are connected by a water pipe, and the water pump 28 and the spraying device 19 are connected by a water pipe. The water pump 28 and the spraying device 19 are existing technologies and are not limited thereto.

[0031] An array of bent plates 35 are fixedly connected to the outer surface of the first rotating shaft 6. A drive device 29 is fixedly connected to one side of the top frame 2. A lifting frame 30 is fixedly connected to the upper side of the sealing cover 5. The drive device 29 is used to drive the lifting frame 30 to lift. As the first rotating shaft 6 rotates, the bent plates 35 can stir the water flow at the bottom, increasing the contact area and frequency between the water and the dust-laden gas, and promoting the more complete capture of dust by water droplets.

[0032] Furthermore, the drive device 29 is a screw transmission mechanism. The output shaft of the servo motor in the drive device 29 drives the screw to rotate. A side plate is threaded onto the screw, and the side plate is fastened to the lifting frame 30. In this way, the lifting frame 30 can drive the sealing cover 5 to adjust up and down. The drive device 29 is existing technology and is not limited thereto.

[0033] The bottom of the processing cylinder 3 is provided with a second circular groove 45, and the bottom of the second circular groove 45 is provided with a first circular groove 44. A stop block 47 is fixedly connected to the lower side of the first rotating shaft 6. The stop block 47 is located inside the first circular groove 44. A sealing ring 48 is fixedly connected to the outer surface of the stop block 47. The sealing ring 48 is located inside the second circular groove 45.

[0034] A connecting pipe 43 is fixedly connected between the treatment cylinder 3 and the treatment box 4. One side of the first filter plate 16 faces the side of the connecting pipe 43. Two second filter plates 46 are snap-fitted and sealed on one side of the treatment box 4. The second filter plates 46 are located below the first filter plates 16. The interior of the treatment cylinder 3 is connected to the interior of the storage box 42 through a pipe, and the interior of the treatment box 4 is connected to the interior of the storage box 42 through a pipe. Rubber pads are fixedly provided on the side of the second filter plates 46 closest to the outside to improve the sealing of the second filter plates 46 during installation. The wastewater falls into the bottom of the treatment box 4 through the second filter plates 46. The first filter plates 16 are arranged in a circumferential manner, and the adjacent first filter plates 16 are in close contact with each other to ensure that the industrial waste gas can still be filtered when the first filter plates 16 are rotated and adjusted.

[0035] A sealing plate 49 is slidably provided on one side of the intake pipe 10. The sealing plate 49 is located inside the intake pipe 10. A support plate 51 is fixedly connected to the upper side of the sealing cover 5. An electric push rod 50 is fixedly connected to one side of the support plate 51. The telescopic end of the electric push rod 50 is fastened to the sealing plate 49. The electric push rod 50 is an electric actuator to achieve the effect of extending or retracting the electric push rod 50. The electric push rod 50 is existing technology and is not limited thereto.

[0036] In addition, a controller is fixedly connected to one side of the top frame 2. The electric push rod 50, the first servo motor 52, the second servo motor 53 and the third servo motor 54 are electrically connected to the controller. Whenever a new filter bag 9 needs to be replaced, the controller will activate the electric push rod 50, causing the telescopic end of the electric push rod 50 to move the sealing plate 49 to block the air inlet pipe 10 and cut off the injection of industrial waste gas. In this way, the filter bag 9 moves to below the air inlet pipe 10 as the first rotating shaft 6 rotates. The controller will then activate the electric push rod 50 again, and the telescopic end of the electric push rod 50 will move the sealing plate 49 away from the air inlet pipe 10, allowing the industrial waste gas to be injected again. At this time, the new filter bag 9 can filter the industrial waste gas better.

[0037] In use, this invention involves filling the bottom of the treatment cylinder 3 with an appropriate amount of water and then starting an external exhaust fan. The exhaust fan's pipe is connected to the air inlet pipe 10, allowing industrial waste gas to enter the treatment cylinder 3 through the air inlet pipe 10. The air inlet pipe 10 aligns with the groove 8 of the circular plate 7, allowing the waste gas to first contact the filter bag 9. The filter bag 9 then filters the waste gas and the dust within it. As the filtration efficiency of the filter bag 9 decreases or the filtration cycle completes, the controller activates the first servo motor 52. The output shaft of the first servo motor 52 drives the fourth rotating shaft 33 to rotate. Due to the meshing transmission between the fourth rotating shaft 33 and the second gear 31, the fourth rotating shaft 33 drives the first rotating shaft 6 to rotate, allowing the dust-accumulated filter bag 9 to move away from the air inlet pipe 10. As the first rotating shaft 6 drives the circular plate 7 to rotate, a new filter bag 9 can be realigned below the air inlet pipe 10. The continuously distributed filter bags 9 can continuously filter industrial waste gas, reducing the frequency of filter bag replacement. After all filter bags 9 have been used, the controller activates the electric push rod 50. The telescopic end of the electric push rod 50 drives the sealing plate 49 to move into the air inlet pipe 10 and seal the air inlet pipe 10, cutting off the entry of industrial gas. Subsequently, the controller activates the second servo motor 53. The output end of the second servo motor 53 drives the fourth gear 38 on the fifth rotating shaft 37 to rotate. The second rack 39 and the fourth gear 38 mesh and drive each other. In this way, the second rack 39 can move in the U-shaped box 36 and drive the bristle soft brush 41 in the collar frame 40 to clean the dust attached to the outside of the filter bags 9, removing the surface dust. At this time, the dust is in contact with water and adheres to the surface of the water. By using the dual measures of filter bag 9 switching and filter bag 9 cleaning, the waste gas treatment time can be greatly extended. The operation is simple and the work efficiency of waste gas treatment is improved.

[0038] Before the industrial waste gas enters the treatment chamber 3, the spraying device 19 and water pump 28 are activated in advance. At this time, the water pump 28 can send water from the water tank to the spraying device 19, and then the nozzles of the spraying device 19 spray water mist. When the treated industrial waste gas enters the treatment chamber 4 through the connecting pipe 43, the water mist will come into contact with the dust in the waste gas to further filter the filtered industrial waste gas. At the same time, the controller can start the third servo motor 54 to switch back and forth between forward and reverse rotation. Then, the output shaft of the third servo motor 54 will drive the second rotating shaft 11 to rotate. Due to the meshing transmission of the two bevel gears 14, the second rotating shaft 11 can drive the third rotating shaft 13 to rotate. In this way, the array of first filter plates 16 can rotate sequentially to the direction of the connecting pipe 43. At this time, the first filter plates 16 can rotate and be replaced sequentially. In this way, all the first filter plates 16 can filter dust continuously, avoiding the problem of a single first filter plate 16. Dust buildup reduces filtration efficiency. At this time, the output shaft of the third servo motor 54 will also drive the first gear 21 to rotate. As the first gear 21 rotates, the first rack 23 can move up and down. This allows the two rollers 27 below the double-headed plate 26 to reciprocate. When the two rollers 27 descend, they press against the lower inclined plate 25, causing the two elastic sliders 18 to move relative to each other along the two round rods 17, thus widening the distance between the two spraying devices 19. When the two rollers 27 rise, they slowly release the pressure on the lower inclined plate 25, allowing the two elastic sliders 18 to move towards each other, thus narrowing the distance between the two spraying devices 19. This allows the spraying devices 19 to reciprocate and achieve uniform treatment of the working exhaust gas, ensuring that the spraying mechanism can cover the industrial exhaust gas inside the treatment box 4 and avoid dead zones in local treatment. At the same time, the distance adjustment of the spraying mechanism and the rotation adjustment of the first filter plate 16 are performed synchronously.

[0039] When the industrial waste gas treatment is completed, the drive device 29 is activated. The drive device 29 can move the sealing cover 5 below the lifting frame 30 upward. At this time, the arrayed filter bags 9 can rise to a higher position, which facilitates the subsequent replacement of new filter bags 9 and ensures the treatment effect of the industrial waste gas dust treatment device. Then, when the sealing cover 5 moves upward, the first rotating shaft 6 will drive the stop block 47 and the sealing ring 48 to rise, away from the first circular groove 44 and the second circular groove 45, opening the first circular groove 44, allowing the contaminated water to enter the storage through the first circular groove 44 and the pipe. The storage tank 42 does not need to be opened separately, saving time and effort. At the same time, the sprayed water is filtered by the second filter plate 46 and flows into the storage tank 42 through the pipe. This facilitates the subsequent centralized treatment of sewage and ensures that the sewage meets the discharge standards. When the filter bag 9 needs to be replaced, the drive device 29 can drive the sealing cover 5 to move down to seal the entire treatment cylinder 3.
