Description

Technical Field

[0001] This invention belongs to the field of industrial waste gas treatment technology, specifically referring to a high-efficiency industrial waste gas treatment device. Background Technology

[0002] During industrial production, chemical plants, steel mills, pharmaceutical plants, coking plants, and oil refineries emit large amounts of industrial waste gas, which mainly includes particulate matter, flue gas, odorous gases, and toxic and harmful gases. This not only causes serious environmental pollution but also directly threatens human health.

[0003] The existing high-efficiency industrial waste gas treatment equipment currently has the following problems: Existing industrial waste gas high-efficiency treatment equipment, when using centrifugal force to remove particulate matter from waste gas, can often only remove larger particles, while the removal efficiency for smaller particles is relatively low. In addition, traditional industrial waste gas high-efficiency treatment equipment cannot clean particulate impurities accumulated on the filter screen surface, thereby reducing the air permeability of the filter screen. Therefore, it cannot meet the current demand for efficient industrial waste gas treatment equipment. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this solution provides an efficient industrial waste gas treatment device that can remove small particles from waste gas by centrifugation and clean particulate impurities accumulated on the filter screen surface.

[0005] The technical solution adopted in this solution is as follows: This solution proposes an efficient industrial waste gas treatment device, including a base, a filter cylinder, an air inlet valve, a centrifugal filtration mechanism, and a resistance-measuring linkage mechanism. The filter cylinder is located on the upper wall of the base, and the air inlet valve is connected to one side of the filter cylinder. The centrifugal filtration mechanism includes a drive component, a separation component, and a filtration component. The drive component is located on one side of the filter cylinder, the separation component is located inside the filter cylinder, and the filtration component is located inside the filter cylinder at the end away from the drive component. The resistance-measuring linkage mechanism includes an air-push component, a sealing component, and a pressure-dividing component. The air-push component is located on the drive component, the sealing component is located on the filtration component, and the pressure-dividing component is located at the end of the filter cylinder away from the drive component.

[0006] As a further preferred embodiment of the present invention, the drive assembly includes a drive motor, a centrifugal ring plate, a centrifugal cylinder, an air inlet, and a drive shaft. The drive motor is located on one side of the filter cylinder. The centrifugal ring plate is rotatably located on the inner wall of the filter cylinder near the drive motor. The centrifugal cylinders are symmetrically located on the inner walls of both ends of the centrifugal ring plate. Multiple sets of air inlets are located on the side of the centrifugal cylinder away from the centrifugal ring plate. The drive shaft passes through the filter cylinder and is located between the output end of the drive motor and the centrifugal cylinder. The separation assembly includes a spiral tube, a separation port, and a wire mesh layer. The spiral tube is connected between the centrifugal cylinders. Multiple sets of separation ports are located on the side wall of the spiral tube. The wire mesh layer is located inside the centrifugal ring plate between the centrifugal cylinders. The air filtration assembly includes an air filtration ring plate, a filter screen, and an exhaust valve. The air filtration ring plate is rotatably located on the inner wall of the filter cylinder away from the drive motor. The filter screen is located on the inner wall of the air filtration ring plate. The exhaust valve is connected to the side of the filter cylinder away from the air inlet valve.

[0007] In use, the exhaust pipe is connected to the inlet valve. After the exhaust gas flows into one end of the filter cartridge, it enters the centrifuge cartridge through the air guide port. The centrifuge cartridge guides the exhaust gas into the spiral tube. The exhaust gas enters tangentially and moves along the spiral tube. The exhaust gas rotates in the static spiral tube. The spiral guide of the spiral tube generates centrifugal force, which forces the airflow to change direction and separates the particles in the exhaust gas. The particles are thrown into the wire mesh layer inside the centrifuge ring plate through the air guide port. The exhaust gas after centrifugation is discharged into the other end of the filter cartridge through the air guide port at the end of the centrifuge ring plate away from the inlet valve. Finally, the exhaust gas is discharged from the exhaust valve after being filtered by the filter screen, completing the filtration of large-diameter particles in the exhaust gas. At this time, the output of the drive motor drives the centrifuge cylinder to rotate through the drive shaft. The centrifuge cylinder drives the centrifuge ring plate and the spiral tube to rotate synchronously. The spiral tube itself rotates at high speed, which enhances centrifugal separation. The particles are thrown against the tube wall by centrifugal force and separated into the wire mesh layer through the separation port, thereby removing small-diameter particles in the exhaust gas and improving the treatment effect of particles in the exhaust gas.

[0008] Preferably, the air-push assembly includes an air-push port, an air-push rod, a linkage magnet, an adjusting spring, and a magnetomagnet. Multiple sets of air-push ports are disposed on the side wall of the centrifugal ring plate. The air-push rod is slidably disposed inside the air-push port. The linkage magnet is disposed on the side of the air-push rod near the filter ring plate. The adjusting spring is disposed between the linkage magnet and the centrifugal ring plate and is in a shortened state. Multiple sets of magnetomagnets penetrate the side wall of the filter ring plate and are disposed opposite to the linkage magnet. The sealing assembly includes a sealing plate and a sealing spring. The sealing plate is slidably disposed at the end of the filter ring plate away from the linkage magnet. The outer diameter of the sealing plate near the filter screen is larger than the inner diameter of the filter ring plate. The sealing spring is located between the magnetomagnet and the sealing plate and is in an extended state. The pressure-dividing assembly includes a pressure sensor, a pressure-dividing tube, an annular filter layer, and a pressure-dividing solenoid valve. The pressure sensor is located on the side of the filter cylinder near the inlet valve, and the pressure measuring end extends into the filter cylinder. Multiple sets of pressure-dividing tubes are connected between the side walls of the filter cylinder on both sides of the filter screen. The annular filter layer is located on the inner wall of the filter cylinder near the exhaust valve. The pressure-dividing solenoid valve is connected to the outer side of the pressure-dividing tube near the inlet valve.

[0009] During operation, smaller particles in the exhaust gas accumulate on the surface of the filter screen after passing through the spiral tube. As the filter screen filters these smaller particles for an extended period, its air permeability decreases, reducing the amount of gas discharged through the exhaust valve. However, the amount of gas entering the filter cartridge through the intake valve remains constant, causing the internal pressure to gradually increase. To prevent excessive pressure from compressing the filter screen and increasing cleaning difficulty, the controller activates the magnetic gyromagnetic electromagnet when the internal pressure reaches the preset pressure threshold of the pressure sensor. The magnetic gyromagnetic electromagnet generates magnetism when energized, and its poles are opposite to those of the linkage magnet and the sealing plate. The gyromagnetic magnet is fixed to the side wall of the filter ring plate and magnetically attracts the linkage magnet and the sealing plate. The sealing plate uses the elastic deformation of the sealing spring to fit against the inner wall of the filter ring plate, sealing the filter screen. During the rotation of the centrifugal ring plate, the linkage magnet drives the gyromagnetic magnet to rotate, which in turn drives the filter ring plate to rotate. The filter ring plate drives the filter screen to rotate, and the dust particles adsorbed on the surface of the filter screen are removed under the action of the rotating airflow, thereby restoring the air permeability of the filter screen. An adhesion layer is pre-set on the inner wall of the filter cylinder between the filter ring plate and the centrifugal ring plate. The dust particles that fall off the surface of the filter screen are adsorbed by the adhesion layer, thus completing the cleaning operation of the filter screen.

[0010] Specifically, a controller is provided on the side wall of the filter cartridge.

[0011] The controller is electrically connected to the drive motor, the magneto-electromagnet, the pressure sensor, and the pressure divider valve.

[0012] The beneficial effects achieved by this solution using the above structure are as follows: Compared with existing technologies, this solution combines a centrifugal filtration mechanism with a resistance-measuring linkage mechanism. Through the setting of drive components, separation components, filtration components, air-propulsion components, sealing components, and pressure-distributing components, it can improve the centrifugal separation efficiency of particulate matter in exhaust gas. The centrifugal ring plate drives the spiral tube to rotate through the centrifugal cylinder, enhancing the centrifugal force on the particulate matter in the exhaust gas flowing through the spiral tube, which facilitates the synchronous removal of small-diameter particulate matter in the exhaust gas. Under the magnetic attraction of the magnetomagnetic body to the linkage magnet, the filtration ring plate and filter screen are driven to rotate synchronously, so that the dust particles adsorbed on the surface of the filter screen are removed under the action of the rotating airflow, thereby ensuring the air permeability of the filter screen and ensuring the filtration effect of the exhaust gas.

The driving motor 6 is located on one side of the filter cylinder 2. The centrifugal ring plate 7 is rotatably mounted on the inner wall of the filter cylinder 2 near the driving motor 6.

The filter screen 17 is disposed on the inner wall of the air filtration ring plate 16. The exhaust valve 18 is connected to the side of the filter cylinder 2 away from the air inlet valve 3.

[0020] The air-push assembly 20 includes an air-push port 21, an air-push rod 22, a linkage magnet 23, an adjusting spring 24, and a magnetomagnet 25. Multiple sets of air-push ports 21 are disposed on the side wall of the centrifugal ring plate 7. The air-push rod 22 is slidably disposed inside the air-push port 21. The linkage magnet 23 is disposed on the side of the air-push rod 22 near the filter ring plate 16. The adjusting spring 24 is disposed between the linkage magnet 23 and the centrifugal ring plate 7 and is in a shortened state. Multiple sets of magnetomagnets 25 penetrate the side wall of the filter ring plate 16 and are disposed opposite to the linkage magnet 23. The sealing assembly 26 includes a sealing plate 27 and a sealing spring 28. The sealing plate 27 is slidably disposed on the filter ring plate 16 away from the linkage magnet 23.

The sealing spring 28 is located between the magneto-electromagnet 25 and the sealing plate 27 and is in an extended state. The pressure dividing assembly 29 includes a pressure sensor 30, a pressure dividing tube 31, an annular filter layer 32, and a pressure dividing solenoid valve 33. The pressure sensor 30 is located on the side of the filter cylinder 2 near the air inlet valve 3, and the pressure measuring end extends into the interior of the filter cylinder 2. Multiple sets of pressure dividing tubes 31 are connected between the side walls of the filter cylinder 2 on both sides of the filter screen 17. The annular filter layer 32 is located on the inner wall of the filter cylinder 2 near the exhaust valve 18. The pressure dividing solenoid valve 33 is connected to the outer side of the pressure dividing tube 31 near the air inlet valve 3.

[0021] The filter cartridge 2 is equipped with a controller 34 on its side wall.

[0022] The controller 34 is electrically connected to the drive motor 6, the magneto-electromagnet 25, the pressure sensor 30, and the pressure divider valve 33.

[0023] In practical use, the exhaust pipe is connected to the inlet valve 3. After the exhaust gas flows into one end of the filter cylinder 2, it enters the centrifuge cylinder 8 through the air guide port 9. The centrifuge cylinder 8 guides the exhaust gas into the spiral tube 12. The exhaust gas enters tangentially and moves along the spiral tube 12. The exhaust gas rotates in the static spiral tube 12. The spiral flow of the spiral tube 12 generates centrifugal force, which forces the airflow to change direction and separates the particles in the exhaust gas. The particles are thrown into the wire mesh layer 14 inside the centrifuge ring plate 7 through the air guide port 9. The exhaust gas after centrifugation is discharged into the other end of the filter cylinder 2 through the air guide port 9 at the end of the centrifuge ring plate 7 away from the inlet valve 3. Finally, the exhaust gas is discharged from the exhaust valve 18 after being filtered by the filter screen 17, thus completing the filtration of large-diameter particles in the exhaust gas. At this time, the controller 34 controls the drive motor 6 to start. The output end of the drive motor 6 drives the centrifuge cylinder 8 to rotate through the drive shaft 10. The centrifuge cylinder 8 drives the centrifuge ring plate 7 and the spiral tube 12 to rotate synchronously. The spiral tube 12 rotates at high speed to enhance centrifugal separation. The particles are thrown against the tube wall by centrifugal force and separated into the wire mesh layer 14 through the separation port 13, thereby removing small-diameter particles in the exhaust gas and improving the treatment effect of particles in the exhaust gas. Smaller particles in the exhaust gas accumulate on the surface of the filter screen 17 after passing through the spiral tube 12. When the filter screen 17 filters the smaller particles in the exhaust gas for a long time, the air permeability decreases, the amount of gas discharged through the exhaust valve 18 decreases, while the amount of gas entering the filter cylinder 2 through the air inlet valve 3 remains unchanged, and the pressure inside the filter cylinder 2 gradually increases. To prevent pressurized gas from excessively compressing the filter screen 17 and increasing its cleaning difficulty, when the air pressure inside the filter cartridge 2 reaches the preset pressure threshold of the pressure sensor 30, the controller 34 controls the magnetomagnet 25 to start. The magnetomagnet 25 is energized and generates magnetism. The magnetomagnet 25 is set with opposite poles to the linkage magnet 23 and the sealing plate 27. The magnetomagnet 25 is fixed to the side wall of the filter ring plate 16 and magnetically attracts the linkage magnet 23 and the sealing plate 27. Under the magnetic attraction of the magnetomagnet 25, the sealing plate 27, in conjunction with the elastic deformation of the sealing spring 28, interacts with the filter ring plate 16. The inner wall is tightly fitted to seal the filter screen 17. During the rotation of the centrifugal ring plate 7, the magnetic magnet 25 is driven to rotate by the linkage magnet 23. The magnetic magnet 25 drives the air filter ring plate 16 to rotate, and the air filter ring plate 16 drives the filter screen 17 to rotate. The dust particles adsorbed on the surface of the filter screen 17 are removed under the action of the rotating airflow, thereby restoring the air permeability of the filter screen 17. An adhesive layer is pre-set on the inner wall of the filter cylinder 2 between the air filter ring plate 16 and the centrifugal ring plate 7. The dust particles that fall off the surface of the filter screen 17 are adsorbed by the adhesive layer, thereby completing the cleaning operation of the filter screen 17. The controller 34 controls the pressure-dividing electric control valve 33 to open. The exhaust gas inside the filter cartridge 2 near the intake valve 3 is centrifuged by the spiral tube 12 and then flows into the filter cartridge 2 away from the intake valve 3 through the pressure-dividing tube 31. The exhaust gas is then discharged from the exhaust valve 18 after being filtered by the annular filter layer 32. After the required rotation cleaning time of filter screen 17 is reached, controller 34 controls the magnetic rotating electromagnet 25 to be de-energized and demagnetized, filter ring plate 16 stops driving filter screen 17 to rotate, sealing plate 27 moves away from filter screen 17, pressure dividing electric control valve 33 closes, and exhaust gas re-enters the interior of filter screen 17 after being separated by spiral tube 12. The gas filtered by filter screen 17 is discharged through exhaust valve 18. When the pressure sensor 30 detects that the pressure inside the filter cartridge 2 is still not lower than the preset pressure threshold after the filter screen is cleaned, it will remind the operator to replace the filter screen 17, thereby ensuring the filtration efficiency of the filter screen 17 for exhaust gas; the above operation can be repeated for the next use.

[0025] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
