Description

Technical Field

[0001] This utility model relates to the field of dust collectors and demisters, and in particular to an ultra-low emission tube bundle dust collector and demister. Background Technology

[0002] Dust collectors and demisters are environmental protection devices used in the industrial field, primarily for removing dust and water mist from industrial waste gases. They are typically installed in industrial chimneys, waste gas treatment equipment, or other locations that generate waste gases. Their working principle utilizes multiple mechanisms to achieve dust and mist removal. For example, inertial collisions cause dust and mist droplets to collide with the collection surface and be captured when the airflow changes direction; centrifugal force causes particles to be thrown against the wall of the device in the rotating airflow, thus separating them; and filter materials can be used to finely filter the waste gas, intercepting tiny dust particles and mist droplets. There are various types of dust collectors and demisters, including cyclone dust collectors, baghouse dust collectors, electrostatic precipitators, and wet demisters. Different types of dust collectors and demisters are suitable for different operating conditions and waste gas characteristics, playing an important role in reducing air pollution, protecting the ecological environment, and ensuring the normal operation of industrial production, thus helping to reduce the harm of waste gas emissions to the environment and human health.

[0003] Tube bundle dust and mist collectors are high-efficiency devices used for industrial flue gas treatment. They mainly consist of tube bundle units, a support structure, and a flushing system. Their working principle utilizes the special structure of the tube bundle; when dust- and mist-laden flue gas passes through it, dust particles and mist droplets collide with and adhere to the inner wall of the tube bundle under the influence of inertia, centrifugal force, and gravity, thus achieving gas-liquid and gas-solid separation. This equipment has high dust and mist removal efficiency, effectively removing fine particulate matter and mist droplets from flue gas, reducing pollutant emissions, and meeting environmental protection requirements.

[0004] However, some existing tube bundle dust collectors and demisters are difficult to adjust the air volume flexibly and accurately according to changes in actual working conditions during operation. When the system faces fluctuations in flue gas flow, increases or decreases in equipment load, or changes in environmental parameters, the equipment cannot adapt and adjust in time. This results in either excessively high air volume, causing energy waste and increased equipment wear, or excessively low air volume, affecting dust collection and demisting efficiency, and even causing a series of problems such as pipe blockage and system pressure imbalance. This greatly restricts the stable operation of the dust collection and demisting system and the achievement of energy conservation and emission reduction goals. Therefore, in order to address the above shortcomings, an ultra-low emission tube bundle dust collector and demister is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an ultra-low emission tube bundle dust collector and demister, aiming to improve the problem that some existing tube bundle dust collectors and demisters cannot effectively regulate the air volume.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ultra-low emission tube bundle dust and mist collector includes a treatment tank. An outlet pipe is fixedly connected to the top of the treatment tank. A drive assembly is located on the top left side of the outlet pipe. Multiple rotating shafts are rotatably connected inside the outlet pipe. Fixed discs are fixedly connected to the exterior of each of the rotating shafts. Adjusting blades are rotatably connected to adjacent sides of the rotating shafts. Guide frames are fixedly connected to opposite sides of the rotating shafts. Guide brackets are slidably connected inside each guide frame. Rotating rings are fixedly connected to adjacent sides of the guide brackets. Multiple toothed blocks are fixedly connected to the exterior of the rotating ring. Multiple limiting brackets are fixedly connected to the inner wall of the rotating ring. Limiting grooves are formed inside the outlet pipe. A dust and mist removal assembly is located inside the treatment tank. A striking assembly is located on the exterior left side of the treatment tank.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a mounting plate, the bottom of which is fixedly connected to the top of the air outlet pipe. A motor is mounted on the right side of the mounting plate, and a drive shaft is fixedly connected to the output end of the motor. A gear is fixedly connected to the outside of the drive shaft, and a protective shell is fixedly connected to the top of the air outlet pipe.

[0010] As a further description of the above technical solution:

[0011] The dust removal and demisting assembly includes two positioning discs, both of which are slidably connected to the inside of the processing tank. Multiple dust removal pipes are fixedly connected to the inside of each positioning disc.

[0012] As a further description of the above technical solution:

[0013] The processing tank is fixedly connected to a fixing ring inside, and multiple sliding rods are fixedly connected to the bottom of the fixing ring. Each of the multiple sliding rods is fitted with a spring, and a limit plate is fixedly connected to the bottom of each of the multiple sliding rods.

[0014] As a further description of the above technical solution:

[0015] The striking assembly includes a second motor, the right side of which is mounted on the left side of the processing tank. The output end of the second motor is fixedly connected to a second drive shaft, and multiple cams are fixedly connected to the outside of the second drive shaft.

[0016] As a further description of the above technical solution:

[0017] The gear and the tooth block are meshed together, and the external drive shaft is rotatably connected to the inside of the protective shell.

[0018] As a further description of the above technical solution:

[0019] The limiting frame is externally slidably connected to the inside of the limiting groove, and the adjusting blade is externally slidably connected to the inside of the air outlet pipe;

[0020] As a further description of the above technical solution:

[0021] The top of the cam contacts the bottom of one of the positioning disks, and the outside of the slide rod is slidably connected to the inside of the other positioning disk.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, motor one drives gear one to rotate via drive shaft one. The gear meshes with the toothed blocks on the outside of the rotating ring, causing the rotating ring to rotate. The limiting frame on the inner wall of the rotating ring slides in the limiting groove inside the exhaust pipe to ensure the stability of the movement. The rotating ring drives the guide frame to move, and the guide frame slides in the guide frame, thereby driving the rotating shaft to rotate, and finally driving the regulating blade to rotate. The operator can change the distance between the regulating blades by controlling the speed of motor one according to the actual working conditions. When the waste gas treatment volume is large, the distance between the regulating blades is increased to accelerate the gas flow rate and improve the treatment efficiency; when the treatment volume is small, the distance is reduced to ensure the treatment effect, so that the equipment can operate efficiently under different working conditions.

[0024] 2. In this invention, when exhaust gas passes through, dust particles and droplets adhere to the inner wall of the dust collection pipe. Motor 2 drives drive shaft 2 to rotate, causing a cam fixed externally to rotate in a circular motion. The edge of the cam intermittently presses against the positioning plate, causing the positioning plate to slide downwards against the spring force on the slide rod. When the cam protrusion rotates, the spring, by its own elasticity, causes the positioning plate to quickly return to its original position, generating high-frequency vibration. This vibration is transmitted to the dust collection pipe, shaking off water droplets and dust particles adhering to its inner wall, preventing blockage and maintaining the high-efficiency filtration performance of the dust collection pipe. Frequent manual cleaning is unnecessary, effectively improving overall cleaning efficiency and the continuity of equipment operation. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of an ultra-low emission tubular bundle dust collector and demister, comprising a treatment tank 1, which serves as the supporting structure for the entire dust collector and demister. An outlet pipe 2 is fixedly connected to the top of the treatment tank 1, and the outlet pipe 2 transports the clean gas after dust and mist removal treatment. A drive assembly is located on the top left side of the outlet pipe 2, including a mounting plate 3. The bottom of the mounting plate 3 is fixedly connected to the top of the outlet pipe 2, and a motor 4 is mounted on the right side of the mounting plate 3. The mounting plate 3 provides a support platform for the motor 4 in the drive assembly. A drive shaft 5 is fixedly connected to the output end of the motor 4, which is the power source for the entire drive assembly to achieve the rotation function of the adjusting blade 10. A gear 6 is fixedly connected to the outside of the drive shaft 5, and the gear 6 rotates synchronously with the rotation of the drive shaft 5. The gear 6 and the gear block 14 are meshed. A protective shell 7 is fixedly connected to the top of the exhaust pipe 2. The external part of the drive shaft 5 is rotatably connected to the inside of the protective shell 7. Multiple rotating shafts 8 are rotatably connected inside the exhaust pipe 2. The function of the rotating shafts 8 is to transmit rotational power to the regulating vane 10, so as to realize the rotation of the regulating vane 10. The external parts of the multiple rotating shafts 8 are fixedly connected to the fixing plate 9. The main function of the fixing plate 9 is to provide mounting support points for the regulating vane 10. The regulating vane 10 is rotatably connected to the adjacent side of the multiple rotating shafts 8. The external part of the regulating vane 10 is slidably connected to the inside of the exhaust pipe 2. The regulating vane 10 can rotate flexibly under the drive of the rotating shaft 8. By changing the distance between the regulating vanes 10, the airflow can be precisely controlled to meet the exhaust gas treatment needs under different working conditions.

[0034] Reference Figures 2 to 4Multiple rotating shafts 8 are fixedly connected to guide frames 11 on opposite sides. Guide frames 12 are slidably connected inside the multiple guide frames 11. The precise sliding of the guide frames 12 within the guide frames 11 ensures the smooth and reliable rotation of the rotating ring 13, thereby achieving precise control of the regulating blade 10. Multiple guide frames 12 are fixedly connected to the adjacent sides of the rotating ring 13. Multiple toothed blocks 14 are fixedly connected to the outside of the rotating ring 13. The rotating ring 13 is connected to the gear 6 through the meshing of the toothed blocks 14 and performs circumferential motion under the drive of the gear 6. Multiple limiting frames 15 are fixedly connected to the inner wall of the rotating ring 13. A limiting groove 16 is opened inside the air outlet pipe 2. The limiting frame 15 is slidably connected to the inside of the limiting groove 16. The function of the limiting frame 15 is to limit and guide the rotation of the rotating ring 13, prevent the rotating ring 13 from deviating or shaking during rotation, and ensure that the rotating ring 13 can rotate along the predetermined circumferential trajectory. The treatment tank 1 is equipped with a dust removal and demisting assembly, which includes two positioning plates 17. The two positioning plates 17 are slidably connected to the inside of the treatment tank 1. Multiple dust removal pipes 18 are fixedly connected inside the positioning plates 17. The main function of the positioning plates 17 is to fix and support the dust removal pipes 18. When the exhaust gas passes through the dust removal pipes 18, dust particles and mist droplets are intercepted on the inner wall of the dust removal pipes 18. A knocking component is provided on the left side of the outside of the treatment tank 1.

[0035] Reference Figure 1 and Figure 5The treatment tank 1 is internally fixedly connected to a fixing ring 19, and multiple sliding rods 20 are fixedly connected to the bottom of the fixing ring 19. The function of the fixing ring 19 is to provide a fixed support point for the sliding rods 20 and to limit the movement of the positioning disk 17. The external sliding rods 20 are slidably connected to the inside of another positioning disk 17. Springs 21 are sleeved on the outside of each sliding rod 20. When the cam 25 intermittently squeezes the positioning disk 17 and causes displacement, the springs 21 will be stretched by the displacement of the other positioning disk 17. When the squeezing action of the cam 25 disappears, the springs 21 use their own elasticity to reset the positioning disk 17, thereby shaking off the water droplets and dust particles attached to the inner wall of the dust removal pipe 18. The bottom of each sliding rod 20 is fixedly connected to a limiting disk 22. The function of the limiting disk 22 is to prevent the sliding rods 20 from coming out of the sliding holes of the positioning disk 17, and at the same time to limit the downward movement of the positioning disk 17. The limiting and striking assembly includes a second motor 23, which is mounted on the left side of the processing tank 1. The second motor 23 is the power source for the striking assembly to shake the dust removal pipe 18 off. The output end of the second motor 23 is fixedly connected to a second drive shaft 24. Multiple cams 25 are fixedly connected to the outside of the second drive shaft 24. The second drive shaft 24 transmits the rotational power of the second motor 23 to the cams 25. The top of the cam 25 contacts the bottom of one of the positioning disks 17. When the second motor 23 drives the second drive shaft 24 to rotate at a constant speed, the edge of the cam 25 will intermittently contact the bottom of one of the positioning disks 17. The gradually increasing thrust causes the positioning disk 17 to slide downward against the elastic force of the spring 21. When the protruding part of the cam 25 rotates, the positioning disk 17 will quickly return to its original position under the elastic restoring force of the spring 21, thereby generating high-frequency vibration and shaking off the water droplets and dust particles attached to the inner wall of the dust removal pipe 18.

[0036] Working Principle: When using this tube bundle type dust collector and demister, starting the motor 4 drives the drive shaft 5 and gear 6 to rotate. The meshing between gear 6 and gear block 14 causes the rotating ring 13 to rotate, which in turn causes the limiting frame 15 to slide inside the limiting groove 16. As the rotating ring 13 rotates, it drives the guide frame 12 to perform circular motion. The sliding of the guide frame 12 inside the guide frame 11 causes the guide frame 11 to rotate, which in turn drives the rotating shaft 8 to rotate. This, in turn, drives the adjusting blade 10 to rotate, allowing adjustment of the adjusting blade 10 and the adjusting... The spacing between the blades 10 allows for effective adjustment of the airflow. During the treatment of exhaust gas, the motor 23 drives the drive shaft 24 to rotate, which in turn drives the cam 25 to perform circular motion. At this time, the cam 25 intermittently presses one of the positioning discs 17 to cause displacement, which in turn stretches the spring 21 under the displacement of the other positioning disc 17. The spring force of the spring 21 then allows the positioning disc 17 to reset, thus shaking off the water droplets and dust particles attached to the inner wall of the dust removal pipe 18, thereby greatly improving the treatment efficiency.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
