Description

Technical Field

[0001] This application relates to the field of waste gas treatment technology, and in particular to a cyclone separator for waste gas treatment towers. Background Technology

[0002] Industrial waste gas treatment is a crucial issue in the environmental protection field. With increasingly stringent environmental regulations, enterprises are demanding more waste gas treatment equipment. Common waste gas treatment technologies include adsorption, catalytic combustion, and wet scrubbing, among which wet scrubbing is widely used due to its high treatment efficiency and wide applicability. However, wet scrubbing generates a large number of small droplets containing pollutants during the process. These droplets need to be further removed by separation equipment to avoid secondary pollution. Cyclone separation technology, as a highly efficient gas-liquid separation method, is widely used in such scenarios.

[0003] However, existing cyclone separators have insufficient separation efficiency and are inconvenient for workers to install and disassemble. To solve these problems, a cyclone separator for waste gas treatment towers is proposed. Utility Model Content

[0004] The purpose of this application is to provide a cyclone separator for waste gas treatment towers, which has the advantages of improved separation efficiency and ease of installation and disassembly by staff.

[0005] This application provides a cyclone separator for a waste gas treatment tower, employing the following technical solution: A cyclone separator for a waste gas treatment tower includes a tower body. A sealing cover is provided on the upper surface of the tower body. A fixed pipe is fixedly connected inside the sealing cover. A movable rod passes through the inside of the fixed pipe. A limiting block is fixedly connected to the surface of the movable rod. A limiting groove is formed inside the fixed pipe. The limiting block passes through the limiting groove. Springs are sleeved on the surfaces of the fixed pipe and the movable rod. A clamping plate is fixedly connected to one end of the movable rod. A positioning tube is fixedly connected to the lower surface of the clamping plate. A telescopic tube is fixedly connected to the upper surface of the clamping plate. The positioning tube and the telescopic tube are connected. A central tube is provided inside the tower body. The positioning tube passes through the interior of the central tube. A guide vane is fixedly connected to the surface of the central tube. An air inlet is fixedly connected to the surface of the tower body. An air outlet is fixedly connected to the upper surface of the sealing cover. A first flange is fixedly connected to the lower surface of the sealing cover. A second flange is fixedly connected to the upper surface of the tower body.

[0006] By adopting the above technical solution, the central tube provides a stable path for the rising channel of the swirling exhaust gas, avoiding airflow turbulence. The guide vanes can guide the exhaust gas entering the tower to form an orderly swirling flow. Through centrifugal force, impurities in the exhaust gas are thrown towards the tower wall, preventing the guide vanes from shifting under the impact of high-speed airflow and ensuring long-term stable separation effect. The clamping plate drives the positioning tube to be tightly inserted into the interior of the central tube, which can not only install and fix the central tube inside the tower, but also buffer the vibration of the equipment during operation to protect the central tube from damage. This makes it convenient for staff to install and disassemble the central tube and guide vanes.

[0007] Preferably, the first flange overlaps the upper surface of the second flange, and both the first and second flanges have threaded holes on their surfaces. There are multiple threaded holes, which are evenly arranged on the surfaces of the first and second flanges.

[0008] By adopting the above technical solution, the multiple threaded holes evenly arranged on the surfaces of the first and second flanges can ensure that the force is evenly distributed at each point when the flanges are connected, avoiding local stress concentration that could cause flange deformation, thereby ensuring the stability of the connection between the sealing cover and the tower body and reducing the risk of seal failure due to flange deformation.

[0009] Preferably, the internal thread of the threaded hole is connected to a fixing bolt, and the first flange and the second flange are fixedly connected by the fixing bolt.

[0010] By adopting the above technical solution, the threaded connection between the fixing bolt and the threaded hole is easy to disassemble and assemble. When it is necessary to open the sealing cover to inspect the internal components of the tower in the future, there is no need to damage the equipment structure, which reduces the difficulty of maintenance. At the same time, the bolt connection has strong fastness and can maintain the stable connection of the flange for a long time, preventing the sealing cover from loosening during equipment operation.

[0011] Preferably, the upper surface of the tower body and the lower surface of the sealing cover are provided with mounting grooves, and a sealing ring is provided inside the mounting groove. The sealing ring is made of rubber material.

[0012] By adopting the above technical solution, the rubber sealing ring is filled in the installation groove, which can fully fill the gap between the tower body and the sealing cover. The elastic properties of the rubber can adapt to the slight deformation during equipment operation, greatly enhance the sealing performance of the connection, effectively prevent exhaust gas from leaking from the flange gap, and avoid environmental pollution and a decrease in exhaust gas treatment efficiency.

[0013] Preferably, the tower body and sealing cover are made of carbon steel lined with plastic, the central tube is made of corrosion-resistant alloy material, and the guide vanes are made of polytetrafluoroethylene material.

[0014] By adopting the above technical solutions, the tower body and sealing cover are made of carbon steel lined with plastic, the central tube is made of corrosion-resistant alloy and the guide plate is made of polytetrafluoroethylene. All three materials are suitable for corrosive media that may exist in the waste gas treatment scenario, which can effectively slow down the corrosion rate of the equipment, extend the service life of each component and reduce the equipment replacement cost.

[0015] Preferably, the guide vanes are arranged in a spiral shape on the surface of the central tube, the spiral angle of the guide vanes is 30-45 degrees, and the center line of the air inlet coincides with the tangent of the tower body circumference.

[0016] By adopting the above technical solution, the guide vanes arranged in a spiral shape at 30-45 degrees can accurately control the intensity of the exhaust gas swirling flow. This ensures that the centrifugal force is sufficient to separate impurities while avoiding excessive pressure loss due to excessive swirling flow. The center line of the air inlet coincides with the tangent of the tower body, allowing the exhaust gas to flow directly along the tangential direction after entering the tower body. Combined with the spiral guide vanes, a stable swirling flow is quickly formed, reducing airflow impact loss and further improving separation efficiency.

[0017] Preferably, there are two sets of the fixed tube, movable rod, spring and clamping plate, and the other set of fixed tube, movable rod, spring and clamping plate is located inside the tower body, and the positions of the two sets of fixed tube, movable rod, spring and clamping plate are corresponding.

[0018] By adopting the above technical solution, two sets of fixed tubes, movable rods, springs and clamping plates arranged opposite to each other can form a bidirectional clamping of the central tube from the sealing cover side and the inside of the tower body. Compared with a single clamping structure, it can more accurately ensure the coaxiality of the central tube inside the tower body, prevent the central tube from tilting due to uneven force on one side, ensure that the guide vanes guide the airflow in the same direction, and maintain a stable separation effect.

[0019] Preferably, the air outlet is connected to the telescopic pipe, and a drain outlet is fixedly connected to the lower surface of the tower body, with a valve provided on the surface of the drain outlet.

[0020] By adopting the above technical solution, the air outlet is connected to the telescopic pipe, which can adapt to the displacement of the movable rod caused by clamping or buffering, and avoid the exhaust channel from breaking or failing to seal due to component movement; the drain port on the lower surface of the tower can promptly discharge the liquid impurities that fall along the tower wall after separation, prevent liquid from accumulating at the bottom of the tower, avoid liquid accumulation corroding the tower or interfering with the airflow swirl, and ensure continuous operation of the equipment.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This waste gas treatment tower cyclone separator, by setting a central tube and guide vanes, provides a stable path for the rising channel of the swirling waste gas, avoiding airflow turbulence. The guide vanes are fixed to the surface of the central tube, which guides the waste gas entering the tower to form an orderly swirling flow. Through centrifugal force, impurities in the waste gas are thrown towards the tower wall. The two work together to ensure the basic function of cyclone separation. At the same time, the fixing effect of the central tube on the guide vanes can prevent the guide vanes from shifting under the impact of high-speed airflow, ensuring long-term stable separation effect. By setting a fixed tube, movable rod and spring, the clamping plate can drive the positioning tube to be tightly inserted into the inside of the central tube. This not only fixes the central tube inside the tower, but also buffers the vibration of the equipment during operation from damaging the central tube, thus facilitating the installation and disassembly of the central tube and guide vanes by the staff.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A cyclone separator for waste gas treatment tower, referring to... Figure 1 , Figure 3 and Figure 4The system includes a tower body 1. A sealing cover 2 is provided on the upper surface of the tower body 1. A fixing pipe 5 is fixedly connected inside the sealing cover 2. A movable rod 7 passes through the inside of the fixing pipe 5. A limit block 8 is fixedly connected to the surface of the movable rod 7. A limit groove 6 is formed inside the fixing pipe 5, and the limit block 8 passes through the limit groove 6. Springs 9 are sleeved on the surfaces of the fixing pipe 5 and the movable rod 7. By setting up the fixing pipe 5, the movable rod 7, and the springs 9, the clamping plate 13 can drive the positioning pipe 14 to be tightly inserted into the inside of the central pipe 3. This not only fixes the central pipe 3 inside the tower body 1 but also buffers the vibration of the equipment during operation from damaging the central pipe 3, thus facilitating the installation and removal of the central pipe 3 and the guide vane 4 by the operators. A clamping plate 13 is fixedly connected to one end of the movable rod 7. A positioning pipe 14 is fixedly connected to the lower surface of the clamping plate 13, and a telescopic pipe 12 is fixedly connected to the upper surface of the clamping plate 13. Pipe 14 is connected to telescopic pipe 12. A central pipe 3 is set inside the tower body 1. The positioning pipe 14 passes through the interior of the central pipe 3. A guide plate 4 is fixedly connected to the surface of the central pipe 3. By setting the central pipe 3 and the guide plate 4, the central pipe 3 provides a stable path for the rising channel after the exhaust gas swirls, avoiding airflow turbulence. The guide plate 4 is fixed to the surface of the central pipe 3, which can guide the exhaust gas entering the tower body 1 to form an orderly swirl. Through centrifugal force, the impurities in the exhaust gas are thrown towards the tower wall. The two work together to ensure the basic function of swirl separation. At the same time, the fixing effect of the central pipe 3 on the guide plate 4 can prevent the guide plate 4 from being displaced under the impact of high-speed airflow, ensuring the long-term stability of the separation effect. An air inlet 10 is fixedly connected to the surface of the tower body 1. An air outlet 11 is fixedly connected to the upper surface of the sealing cover 2. A first flange 15 is fixedly connected to the lower surface of the sealing cover 2. A second flange 17 is fixedly connected to the upper surface of the tower body 1.

[0026] Please see Figure 1 , Figure 2 and Figure 3 The first flange 15 overlaps the upper surface of the second flange 17. Both the first flange 15 and the second flange 17 have multiple threaded holes 16 evenly arranged on their surfaces. This even arrangement of threaded holes 16 ensures uniform stress distribution at all points during flange connection, preventing localized stress concentration and flange deformation. This, in turn, guarantees the stability of the connection between the sealing cover 2 and the tower body 1, reducing the risk of seal failure due to flange deformation. The threaded holes 16 are internally connected to fixing bolts 18. The first flange 15 and the second flange 17 are fixedly connected by these bolts. The threaded connection between the fixing bolts 18 and the threaded holes 16 simplifies disassembly and assembly. Later, when the sealing cover 2 needs to be opened for maintenance of internal tower components, the equipment structure can be repaired without damage, reducing maintenance difficulty. Simultaneously, the bolt connection provides strong fastening, maintaining a stable flange connection over a long period and preventing the sealing cover 2 from loosening during equipment operation.

[0027] Please see Figure 2 , Figure 3 and Figure 4 The upper surface of the tower body 1 and the lower surface of the sealing cover 2 are both provided with mounting grooves 19. A sealing ring 20 is installed inside the mounting groove 19. The sealing ring 20 is made of rubber material. The rubber sealing ring 20 fills the mounting groove 19 and can fully fill the gap between the tower body 1 and the sealing cover 2. The elasticity of the rubber can adapt to the slight deformation during equipment operation, greatly enhance the sealing performance of the connection, effectively prevent exhaust gas from leaking from the flange gap, avoid environmental pollution and the decline in exhaust gas treatment efficiency. The tower body 1 and the sealing cover 2 are made of carbon steel lined with plastic material, the central tube 3 is made of corrosion-resistant alloy material, and the guide plate 4 is made of polytetrafluoroethylene material. The three materials of the tower body 1 and the sealing cover 2 are made of carbon steel lined with plastic, the central tube 3 is made of corrosion-resistant alloy material, and the guide plate 4 is made of polytetrafluoroethylene material. All three materials are suitable for the corrosive media that may exist in the exhaust gas treatment scenario, which can effectively slow down the corrosion rate of the equipment, extend the service life of each component, and reduce the equipment replacement cost.

[0028] Please see Figure 1 , Figure 2 and Figure 5The guide vanes 4 are arranged in a spiral shape on the surface of the central tube 3. The spiral angle of the guide vanes 4 is 30-45 degrees. The center line of the air inlet 10 coincides with the tangent of the circumference of the tower body 1. The 30-45 degree spiral arrangement of the guide vanes 4 can precisely control the intensity of the exhaust gas swirling flow, ensuring that the centrifugal force is sufficient to separate impurities while avoiding excessive pressure loss due to excessive swirling flow. The coincidence of the center line of the air inlet 10 with the tangent of the circumference of the tower body 1 allows the exhaust gas to flow directly along the tangential direction after entering the tower body 1. Combined with the spiral guide vanes 4, a stable swirling flow is quickly formed, reducing airflow impact loss and further improving separation efficiency. There are two sets of fixed tubes 5, movable rods 7, springs 9, and clamping plates 13. The other set of fixed tubes 5, movable rods 7, springs 9, and clamping plates 13 is located inside the tower body 1. The positions of the two sets of fixed tubes 5, movable rods 7, springs 9, and clamping plates 13 are corresponding. 5. The movable rod 7, spring 9, and clamping plate 13 can form a bidirectional clamping of the central tube 3 from the side of the sealing cover 2 and the inside of the tower body 1. Compared with a single clamping structure, it can more accurately ensure the coaxiality of the central tube 3 inside the tower body 1, prevent the central tube 3 from tilting due to uneven force on one side, ensure that the guide vane 4 guides the airflow in the same direction, and maintain a stable separation effect. The air outlet 11 is connected to the telescopic pipe 12. The lower surface of the tower body 1 is fixedly connected to the drain port 21. The surface of the drain port 21 is equipped with a valve. The air outlet 11 is connected to the telescopic pipe 12, which can adapt to the displacement of the movable rod 7 due to clamping or buffering, and avoid the exhaust channel from breaking or failing to seal due to component movement. The drain port 21 on the lower surface of the tower body 1 can promptly discharge the liquid impurities that fall along the tower wall after separation, prevent liquid from accumulating at the bottom of the tower body 1, avoid liquid corrosion of the tower body 1 or interference with airflow swirl, and ensure continuous operation of the equipment.

[0029] The implementation principle of this application embodiment is as follows: First, the central tube 3 is placed inside the tower body 1, and its position is adjusted so that the positioning tube 14 on the upper surface of the clamping plate 13 inside the tower body 1 passes through the interior of the central tube 3. The sealing ring 20 is embedded in the mounting groove 19 on the upper surface of the tower body 1. Then, the positioning tube 14 on the lower surface of the sealing cover 2 is passed through the interior of the central tube 3. The mounting groove 19 on the lower surface of the sealing cover 2 is aligned with the mounting groove 19 of the tower body 1, so that the first flange 15 overlaps the second flange 17, ensuring that the threaded holes 16 of the two sets of flanges correspond one-to-one. The fixing bolts 18 are screwed into the threaded holes 16, and the bolts are tightened to make the sealing cover 2 and the tower body 1 tightly connected. The sealing ring 20 is deformed under pressure to fill the gap and achieve a seal. The two sets of clamping plates 13 move closer to the central tube 3 under the action of the spring 9 to clamp and fix the central tube 3, completing the axial positioning of the central tube 3. At this time, the telescopic tube 12 and the air outlet 11 are naturally connected, forming a... The exhaust channel is formed, and the waste gas to be treated enters from the air inlet 10 on the surface of the tower body 1. Since the center line of the air inlet 10 coincides with the tangent of the circumference of the tower body 1, the waste gas flows along the tangential direction of the tower wall. When it flows through the guide plate 4 on the surface of the central tube 3, a stable vortex is formed under the guidance of the spiral guide plate 4. The impurities in the waste gas are thrown towards the inner wall of the tower body 1 due to centrifugal force. The impurities thrown towards the tower wall fall down along the inner wall surface of the tower body 1 under the action of gravity. When the waste liquid inside the tower body 1 reaches the specified liquid level, the valve on the surface of the drain port 21 is opened, and finally the waste gas is discharged out of the tower through the drain port 21 on the lower surface of the tower body 1, completing the separation of impurities. The purified gas after removing impurities enters the interior of the central tube 3 through the positioning pipe 14 at the bottom of the central tube 3 under the action of vortex, flows upward along the interior of the central tube 3, and then enters the telescopic pipe 12 through the positioning pipe 14 at the top of the central tube 3. Finally, it is discharged from the tower body 1 through the air outlet 11 on the upper surface of the sealing cover 2, thus realizing the purification of waste gas.
