Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to an industrial furnace flue gas particulate separator with cleaning function. Background Technology

[0002] A flue gas particulate separator is an environmentally friendly device used to remove solid particulate matter from industrial flue gas. It is widely used in coal-fired boilers, metallurgy, chemical industry and other fields to reduce air pollution and meet emission standards.

[0003] To achieve the above functions, a prior art Chinese patent (publication number: CN219630887U) discloses a flue gas fouling separator, which includes: a body; a flue gas inlet located on the side of the body near the bottom; a separator filter element located at the top of the body, with a flange on the top of the filter element; a flue gas outlet located on the top of the body opposite to the flue gas inlet and connected to the separator filter element via the flange; and a backflush air inlet located on the top of the body on the same side as the flue gas inlet and connected to the separator filter element via the flange. The flue gas fouling separator adopts an inner and outer cavity design. The inner cavity contains a high-precision filter element, effectively filtering large particles of dust and water vapor in the flue gas, effectively separating flue gas and dust. Furthermore, the backflush air blows dust adhering to the filter element from inside the filter element cavity outwards, significantly improving working efficiency.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation: traditional particulate matter flue gas separators are prone to particulate matter depositing on the inner wall. As the operating time increases, these deposits gradually accumulate, causing frequent clogging of the filter structure and affecting the normal operating efficiency and lifespan of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide an industrial furnace flue gas particulate separator with a cleaning function, in order to solve the problem in the above-mentioned background technology that traditional particulate flue gas separators are prone to particulate matter deposition on the inner wall. As the operating time increases, these deposits will gradually accumulate, leading to frequent clogging of the filter structure, which affects the normal working efficiency and lifespan of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial furnace flue gas particle separator with cleaning function, comprising a vertically installed processing pipe, an air inlet pipe distributed along its tangential direction on one side of the top of the processing pipe, and a slag discharge port at the lower end of the processing pipe;

[0007] A ring track is fixedly connected to the top of the inner side of the treatment tube, and a ring frame is rotatably connected to the outer side of the ring track. A wind-driven plate with a radial structure is fixedly connected to the outer side of the ring frame, and a scraper with a spiral structure is fixedly connected to the bottom of the ring frame, with the scraper and the inner side of the treatment tube in close contact with each other.

[0008] Preferably, the intake pipe and the processing pipe are internally connected, and the end of the intake pipe facing the inside of the processing pipe is aligned with the fan plate, and the processing pipe has a frustum-shaped structure that is wider at the top and narrower at the bottom.

[0009] Preferably, a support rod is fixedly connected to the middle of the lower end of the processing tube via a bracket, and equidistant connecting rods are fixedly connected to the inner side of the scraper. A stabilizing sleeve is fixedly connected to the end of the connecting rod away from the scraper, and the stabilizing sleeve is rotatably connected to the inside of the support rod.

[0010] Preferably, each of the inner sides of the pneumatic plate is fixedly connected with an elastic lever, and the elastic lever has a radial structure facing the center of the annular frame. A filter cartridge is fixedly connected to the top of the processing tube, and the outer side of the filter cartridge is in contact with the pneumatic plate. An exhaust pipe is fixedly connected to the top of the processing tube.

[0011] Preferably, the outer side of the processing tube is fixedly connected with annularly distributed support feet, and the bottom of the processing tube is fixedly connected with two vertically and parallelly distributed guide plates through the support feet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This industrial furnace flue gas particle separator with cleaning function uses the kinetic energy of flue gas to drive the rotation of an annular frame. The frustum-shaped processing tube design generates a progressively accelerating airflow, causing particles of different sizes to settle in a gradient. The cooperation between the spiral scraper and the tube wall ensures efficient collection of settled particles. Combined with the vibration cleaning function of the elastic paddle, it forms the settling and collection of particles and prevents the filter cartridge from clogging.

[0016] Pre-treatment in the water treatment tank effectively reduces flue gas temperature and removes large particles. Subsequent centrifugal separation creates a stepped purification process, significantly improving overall dust removal efficiency. The water treatment tank employs an immersion-type suction pipe design, extending the gas-liquid contact time and enhancing the washing effect.

[0017] The combination design of double guide plates and sliding transport pipe enables automatic switching between continuous slag discharge and sealing, and the baffle linkage mechanism effectively maintains the airtightness of the system. Attached Figure Description

[0025] 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.

[0026] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: an industrial furnace flue gas particle separator with cleaning function, including a vertically installed treatment pipe 1, an air inlet pipe 2 distributed along its tangential direction on one side of the top of the treatment pipe 1, and a slag discharge port 3 at the lower end of the treatment pipe 1; an annular track 4 is fixedly connected to the top of the inner side of the treatment pipe 1, an annular frame 5 is rotatably connected to the outer side of the annular track 4, a pneumatic plate 6 with a radial structure is fixedly connected to the outer side of the annular frame 5, and a scraper 7 with a spiral structure is fixedly connected to the bottom of the annular frame 5, and the scraper 7 and the inner side of the treatment pipe 1 are in close contact with each other; the air inlet pipe 2 and the treatment pipe 1 are internally connected, and the end of the air inlet pipe 2 facing the inside of the treatment pipe 1 is aligned with the pneumatic plate 6, and the treatment pipe 1 has a frustum-shaped structure that is wider at the top and narrower at the bottom; a support rod 8 is fixedly connected to the middle of the lower end of the treatment pipe 1 through a bracket, and connecting rods 10 with equal spacing are fixedly connected to the inner side of the scraper 7, and a stabilizing sleeve 9 is fixedly connected to the end of the connecting rod 10 away from the scraper 7, and the stabilizing sleeve 9 is rotatably connected to the inside of the support rod 8; pneumatic plate 6 is fixedly connected to the inner side of the scraper 7, and the pneumatic plate 6 is rotatably connected to the inner side of the scraper 7. Elastic levers 11 are fixedly connected to the inner middle of the plate 6, and the elastic levers 11 are radially oriented toward the middle of the annular frame 5. A filter cartridge 12 is fixedly connected to the top of the treatment pipe 1, and the outer side of the filter cartridge 12 is in contact with the pneumatic plate 6. An exhaust pipe 13 is fixedly connected to the top of the treatment pipe 1. A ring of equally spaced support feet is fixedly connected to the outer side of the treatment pipe 1, and two vertically and parallelly distributed guide plates 14 are fixedly connected to the bottom of the treatment pipe 1 through the support feet. A transport pipe 16 is slidably connected between the two guide plates 14. A baffle 17 is fixedly connected to one side of the top of the transport pipe 16. The upper guide plate 14 has a discharge hole 15 aligned with the slag discharge port 3 in the middle, and the lower guide plate 14 has a discharge hole 15 at the end away from the baffle 17. An air supply pipe 19 is fixedly connected to the input end of the air inlet pipe 2. A horizontally placed water treatment tank 18 is fixedly connected to the end of the air supply pipe 19 away from the air inlet pipe 2. An air suction pipe 20 is provided inside the water treatment tank 18, and an air suction fan is fixedly connected to the top of the air suction pipe 20. Furthermore, the suction pipe 20 extends downward to the bottom of the inner side of the water treatment tank 18.

[0027] The dust-laden flue gas generated by the industrial furnace is first pretreated by a water treatment tank 18. The water treatment tank 18 is placed horizontally and has an intake pipe 20 inside. An intake fan is fixedly connected to the top of the intake pipe 20 and extends downward to the bottom of the inner side of the water treatment tank 18. When the intake fan is running, the flue gas is drawn into the water phase area of ​​the water treatment tank 18 through the intake pipe 20. The water treatment tank 18 removes some particles and heat from the flue gas through the washing and cooling effect of water.

[0028] Flue gas is discharged from water treatment tank 18 through gas supply pipe 19. The inlet end of gas supply pipe 19 is fixedly connected to air inlet pipe 2. Subsequently, after the flue gas enters treatment pipe 1, particle sedimentation is achieved by tangential air intake and swirling centrifugal effect. Treatment pipe 1 is installed vertically and has a frustum-shaped structure that is wider at the top and narrower at the bottom. This design is conducive to accelerating airflow and enhancing centrifugal force.

[0029] The intake pipe 2 is located on one side of the top of the treatment pipe 1 and is distributed along its tangential direction, and the intake pipe 2 and the treatment pipe 1 are internally connected. The end of the intake pipe 2 facing the inside of the treatment pipe 1 is aligned with the fan plate 6. When the flue gas enters tangentially from the intake pipe 2, it generates a high-speed swirling flow, and the airflow spirals downward. The fan plate 6 is fixedly connected to the outside of the annular frame 5 and is distributed in a radial structure. The airflow directly impacts the fan plate 6, generating driving force. The annular frame 5 is rotatably connected through the annular track 4, which is fixedly connected to the top of the inner side of the treatment pipe 1. The tangential impact of the flue gas pushes the fan plate 6, causing the annular frame 5 to rotate smoothly on the annular track 4.

[0030] The flue gas swirls downwards and accelerates within the frustum structure of treatment pipe 1. Particulate matter settles towards the outer wall due to centrifugal force. Larger particles, due to their higher density, migrate rapidly towards the pipe wall, while smaller particles continue to flow with the airflow. The rotation of the airflow gives the particles outward acceleration, and the converging structure of the pipe wall further increases the airflow velocity, enhancing settling efficiency. The settled particles collect at the lower end of treatment pipe 1 and are discharged through slag discharge port 3.

[0031] The rotation of the annular frame 5 drives the scraper 7, which is fixedly connected to the bottom of the annular frame 5 and has a spiral structure. The scraper 7 adheres closely to the inner wall of the treatment pipe 1 during rotation, scraping the settled particles downwards and gradually guiding them towards the discharge port 3. This ensures that the settled material is not re-entrained by the airflow, improving separation efficiency. To maintain stable rotation of the scraper 7, a support rod 8 is fixedly connected to the lower middle of the treatment pipe 1 via a bracket. Equally spaced connecting rods 10 are fixedly connected to the inner side of the scraper 7, and a stabilizing sleeve 9 is fixedly connected to the other end of the connecting rods 10. The stabilizing sleeve 9 is rotatably connected inside the support rod 8. When the flue gas pushes the annular frame 5 to rotate, the scraper 7 receives radial support through the connecting rods 10 and the stabilizing sleeve 9, preventing swaying or deviation and improving mechanical reliability.

[0032] After the particles are discharged through the slag discharge port 3, they enter the slag treatment system. A ring of equally spaced support feet is fixedly connected to the outside of the treatment pipe 1. Two parallel guide plates 14 are fixedly connected to the support feet. The transport pipe 16 is slidably connected between the two guide plates 14. A baffle 17 is fixedly connected to one side of the top of the transport pipe 16. The upper guide plate 14 has a discharge hole 15 aligned with the slag discharge port 3 in the middle. The lower guide plate 14 also has a discharge hole 15 at its end away from the baffle 17. In the initial state, the particles will fall from the exhaust pipe 13 into the transport pipe 16. At this time, the transport pipe 16 and the lower guide plate 14... A container will be formed to temporarily store the particulate matter. When the particulate matter inside the transport pipe 16 reaches a certain amount, the transport pipe 16 will be driven to slide between the two guide plates 14. At this time, the opening at the bottom of the transport pipe 16 will be aligned with the discharge hole 15 opened by the guide plate 14 below, and the transport pipe 16 will drive the baffle 17 to close the bottom of the slag discharge port 3, thereby discharging the particulate matter inside the transport pipe 16 without affecting the airtightness of the processing pipe 1. The transport pipe 16 can be driven to move by a push rod that runs at a time.

[0033] The filter cartridge 12 is automatically cleaned by the rotation of the pneumatic plate 6 to prevent filter clogging. The filter cartridge 12 is fixedly connected to the top of the treatment pipe 1, and the outer side of the filter cartridge 12 is in contact with the pneumatic plate 6. When the annular frame 5 rotates, the elastic tabs 11 on the inner side of the pneumatic plate 6 are stretched outward due to centrifugal force during rotation, and come into contact with the surface of the filter cartridge 12. The elastic tabs 11 drive the filter cartridge 12 to vibrate and remove accumulated dust particles. After the particles settle in the treatment pipe 1, the lighter gaseous substances pass through the filter cartridge 12 and enter the exhaust pipe 13. The exhaust pipe 13 is fixedly connected to the top of the treatment pipe 1, and the cleaned flue gas is discharged from there.
