Technical Field
[0001] This invention relates to the field of desulfurization tower technology, specifically to a desulfurization enhancement structure within a high-efficiency desulfurization tower. Background Technology
[0002] Traditional desulfurization towers often suffer from uneven gas distribution, local dead zones, and bottom sedimentation in the contact between waste gas and slurry, resulting in limited desulfurization efficiency and insufficient operational stability. To address this, the waste gas is first introduced into the inner wall of the chamber for pressure stabilization and uniform flow. Then, a rotating arc-groove guide plate, combined with multiple sets of unidirectional cylinders, is used to achieve intermittent alternating gas supply, ensuring that the bubbles are evenly distributed to the liquid pool at the bottom of the tower. This effectively eliminates contact dead zones and improves gas-liquid mixing efficiency. Simultaneously, the spray mechanism and stirring components are synchronously driven by the stirring shaft, dynamically tracking the gaps in the waste gas flow to achieve continuous stirring at the bottom of the tower and scale prevention of the liquid film on the tower wall. Combined with a three-dimensional flushing network that integrates top and bottom synchronization and side gaps, the demister is ensured to remain unobstructed for a long time. Thus, uniform gas distribution, thorough slurry mixing, and online anti-clogging of key components are achieved without external intervention, significantly improving the overall desulfurization efficiency and operational reliability of the desulfurization tower.
[0003] Patent CN204220025U discloses an efficiency-enhancing ring and internal structure for high-efficiency desulfurization and purification, including a tower body. The tower body, from top to bottom, comprises a flue gas outlet, a flue gas outlet guide grid, a demister, a spray layer, an efficiency-enhancing ring, a flue gas inlet guide ring, a flue gas inlet, and a desulfurization slurry pool. The spray layer is multi-layered, and each spray layer has an efficiency-enhancing ring for concentrating flue gas. The desulfurization slurry pool includes a pH adjuster, an oxidation air pipe, and a jet agitator. The efficiency-enhancing ring in this patent can be a structure consisting of a protective efficiency-enhancing plate and a support plate positioned below the spray layer, or it can be a ring-shaped arc plate structure at the same height as the spray layer. Furthermore, this patent allows for the installation of a wet electrostatic precipitator above the tower body for deep dust removal. This patent can further improve the removal efficiency of limestone-gypsum wet desulfurization, reduce dust concentration, and save investment and floor space. However, this patent also has the problems of low gas-liquid contact efficiency and dead contact angles. Therefore, a high-efficiency desulfurization tower desulfurization enhancement structure is proposed to solve the above-mentioned problems. Summary of the Invention

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects: This high-efficiency desulfurization tower features an internal desulfurization enhancement structure that stabilizes and evenly distributes waste gas through the inner wall of the chamber, laying the foundation for uniform gas distribution. The stirring shaft drives the stirring rod and the arc groove guide plate to rotate. On one hand, the guide plates sequentially push the one-way cylinders in different directions, allowing the waste gas to enter the liquid pool in a pulse pattern of four alternating groups from eight directions, significantly reducing dead zones and greatly improving gas-liquid contact efficiency. On the other hand, the stirring rod and the arc groove guide plate continuously stir the bottom sediment to prevent caking. At the same time, the arc groove guide plate scrapes off the adhering material on the outside of the one-way cylinder as it slides, achieving self-cleaning. After moving away, the movable cone automatically resets under the action of the elastic spring and pushes out the residue, avoiding blockage. Thus, without external intervention, it simultaneously achieves uniform waste gas distribution, bottom stirring, and online anti-clogging of key components, effectively improving the operational stability and desulfurization efficiency of the desulfurization tower.
[0015] This high-efficiency desulfurization tower features a desulfurization enhancement structure. A stirring shaft drives a rotating tank to rotate synchronously, causing the nozzles on the lower branch pipe to dynamically fill the gaps in the exhaust gas flow, following the arc-groove guide plate. This significantly improves gas-liquid contact efficiency. Simultaneously, the liquid in the supply pipe forms a coordinated three-dimensional spray network with the upper and lower branch pipes, further enhancing the desulfurization effect and generating gypsum precipitate. Some liquid from the upper branch pipe enters the ring pipe through a cross-flow pipe, causing the liquid sprayed from the fine nozzles to flow along the inner wall of the desulfurization tower, forming a liquid film. This effectively reduces precipitate adhesion and scaling. Thus, without requiring additional power, it simultaneously achieves dynamic tracking and coverage of the spray layer, improved gas-liquid contact efficiency, and online scale prevention on the inner wall of the tower, greatly enhancing the operational reliability and overall desulfurization performance of the desulfurization system.
[0016] The high-efficiency desulfurization tower's internal desulfurization enhancement structure allows the dual branch pipes to simultaneously flush the upper and lower sides of the demister through the horizontal spray nozzles, eliminating blind spots in single-sided flushing. At the same time, the dual branch pipes introduce liquid into the C-shaped pipes, enabling the gap spray nozzles to perform directional spraying on the side gaps of the demister, specifically cleaning traditional flushing dead corners such as blade bends and barbs. This forms a three-dimensional flushing network that combines simultaneous upper and lower flushing with side gap flushing, significantly reducing the risk of scaling and clogging, and ensuring the long-term stable operation of the demister.

[0019] 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.
[0020] Please see Figure 1 - Figure 9 An embodiment of the present invention is: a desulfurization efficiency enhancement structure inside a high-efficiency desulfurization tower, including a desulfurization tower body 1, a top cover 2, an exhaust port 3, a liquid extraction port 4, and a gas supply port 8. An efficiency enhancement gas supply mechanism 5 for improving the multi-directional conveying efficiency of exhaust gas is provided at the bottom of the interior of the desulfurization tower body 1. An efficiency-enhancing desulfurization mechanism 6 is installed above the efficiency-enhancing gas supply mechanism 5 to improve the efficiency of waste gas desulfurization. Above the efficiency-enhancing desulfurization mechanism 6 is a demisting and anti-clogging mechanism 7 for clearing blockages; The efficiency-enhancing gas supply mechanism 5 includes an inner cavity wall 501. An agitator 502 is provided on the inner side of the inner cavity wall 501. An agitator frame 503 is fixedly connected to the outer side of the agitator 502. Multiple agitator connecting rods 504 are fixedly connected to the side of the agitator frame 503. An arc groove guide plate 505 is fixedly connected to one end of the agitator connecting rod 504 away from the agitator frame 503. Guide plates 508 are fixedly connected to both ends of each arc groove guide plate 505. A convex ring 506 is fixedly connected to the outer wall of the inner cavity wall 501. Multiple one-way cylinders 507 are fixedly connected to the side of the convex ring 506. A perforated plate 510 and a side groove guide block 512 are fixedly connected to the inner wall of each one-way cylinder 507. A side through groove 513 is opened on the side of the side groove guide block 512. A movable cone block 511 is slidably connected to the inner side of the side groove guide block 512. A guide cone block 514 is fixedly connected to one end of the movable cone block 511.
[0021] A liquid supply pipe 9 is provided above the gas supply port 8, and a processing port 10 and a foot support 11 are fixedly connected to the outer surface of the desulfurization tower body 1.
[0022] The side of the arc groove guide plate 505 is provided with an air passage groove 509. A spring is provided between the movable cone block 511 and the hole plate 510, and the two ends of the spring are fixedly connected to the movable cone block 511 and the hole plate 510 respectively.
[0023] The inner cavity wall 501 is fixedly connected to the bottom inner wall of the desulfurization tower body 1. The stirring shaft 502 is rotatably connected to the bottom of the desulfurization tower body 1. The arc groove guide plate 505 is slidably connected to the convex ring 506. The waste gas to be treated is input through the connected air supply port 8 on the side of the desulfurization tower body 1. The waste gas enters the connected inner cavity wall 501 from the air supply port 8. The waste gas first fills the entire internal space of the inner cavity wall 501. When the stirring shaft 502 rotates under the drive of the bottom reduction motor, the stirring shaft 502 drives multiple stirring rods 504 to make circular motion through the connected stirring frame 503. The arc groove guide plate 505 connected to the stirring rods 504 makes the convex ring 506 that is attached to the outer wall of the inner cavity wall 501 make circular motion together. During this process, the connected guide plate 505 makes the convex ring 506 that is attached to the outer wall of the inner cavity wall 501 make circular motion together. The plate 508 pushes the guide cone block 514 to receive force, causing the guide cone block 514 to slide along the side groove guide block 512 inside the one-way cylinder 507. When the guide cone block 514 moves, the connected movable cone block 511 moves away from the side groove guide block 512. At this time, the exhaust gas in the inner cavity wall 501 passes around the movable cone block 511, then passes through the side passage groove 513 on the side of the side groove guide block 512 and moves to the area around the guide cone block 514. It then flows around the guide cone block 514 to the air passage groove 509 on the side of the arc groove guide plate 505 and enters the bottom liquid pool of the desulfurization tower body 1. During the slow rotation of the arc groove guide plate 505 with the stirring shaft 502, the arc groove guide plate 505 controls four of the eight directions of the one-way cylinders 507 connected to the inner cavity wall 501 to be in an alternating air supply state. The one-way cylinders 507 at different positions on the cavity wall 501 alternately supply gas, allowing the exhaust gas to enter the liquid pool at the bottom of the desulfurization tower 1 evenly. This reduces dead zones and ensures uniform contact between the exhaust gas and liquid, improving contact efficiency. The stirring rod 504 and the arc groove guide plate 505 move to stir the sediment that falls to the bottom of the desulfurization tower 1. At the same time, the arc groove guide plate 505 slides past the one-way cylinders 507 to scrape off the attached sediment. When the arc groove guide plate 505 moves away from the one-way cylinder 507, the movable cone block 511 will be reset by the action of the elastic spring and pop out from the inside of the one-way cylinder 507 to avoid blockage. The inner cavity wall 501 stabilizes and evens the flow of the exhaust gas, laying the foundation for uniform gas distribution. The stirring shaft 502 drives the stirring rod 504 and the arc groove guide plate 507. The rotation of the 05 unit serves two purposes. First, the guide plate 508 sequentially pushes the one-way cylinders 507 in different directions, allowing the exhaust gas to enter the liquid pool in a pulse pattern of four alternating groups from eight directions. This significantly reduces dead zones and improves gas-liquid contact efficiency. Second, the stirring rod 504 and the arc groove guide plate 505 continuously stir the bottom sediment to prevent caking. At the same time, the arc groove guide plate 505 scrapes off the deposits on the outside of the one-way cylinder 507 as it slides, achieving self-cleaning. After moving away, the movable cone 511 automatically resets under the action of the elastic spring and pushes out the residue, avoiding blockage. Thus, without external intervention, the unit simultaneously achieves uniform distribution of exhaust gas, bottom stirring, and online anti-clogging of key components, effectively improving the operational stability and desulfurization efficiency of the desulfurization tower.
[0024] The efficiency-enhancing desulfurization mechanism 6 includes a rotary tank 601, a lower bushing 603 fixedly connected to the bottom surface of the rotary tank 601, multiple lower branch pipes 602 fixedly connected to the outer surface of the rotary tank 601, a hinged pipe 604 fixedly connected to the upper middle part of the rotary tank 601, a sliding ring frame 606 fixedly connected to the end of the lower branch pipe 602 away from the rotary tank 601, a ring support rail 605 slidably connected to the lower part of the sliding ring frame 606, multiple subdivided pipes 607 fixedly connected to the outer surface of the lower branch pipe 602, two nozzles 608 fixedly connected to the end of each subdivided pipe 607, and a pipe support 609 provided above the sliding ring frame 606.
[0025] The liquid supply end pipe 9 is located above the pipe bracket 609. Multiple upper branch pipes 610 are fixedly connected to the outer wall of the liquid supply end pipe 9. Multiple sub-pipes 607 and multiple nozzles 608 are also provided on the outer surface of the upper branch pipes 610. A connecting pipe 611 is fixedly connected to the end of each upper branch pipe 610 away from the liquid supply end pipe 9. A drainage pipe 612 is fixedly connected to the end of each connecting pipe 611 away from the upper branch pipe 610. All drainage pipes 612 are fixedly connected to the same ring pipe 613. Multiple jetting fine pipes 614 are fixedly connected to the outer surface of the ring pipe 613.
[0026] The lower bushing 603 is inserted and connected to the top of the stirring shaft 502. The hinged pipe 604 is rotatably connected to the liquid supply pipe 9. The ring support rail 605 is fixedly connected to the inner wall of the desulfurization tower body 1. The pipe bracket 609 is fixedly connected to the desulfurization tower body 1. The liquid supply pipe 9 extends from the inner wall of the desulfurization tower body 1 through both outer surfaces. When the external pump draws the liquid inside the desulfurization tower body 1 to the liquid supply pipe 9 through the pumping port 4, the liquid inside the liquid supply pipe 9 enters the swivel tank 601 through the hinged pipe 604, then flows to the lower branch pipe 602 connected to the swivel tank 601, and flows to the fine [unclear - possibly a specific product or service] through the lower branch pipe 602. Branch pipe 607 and nozzle 608 are connected, while the swivel tank 601 is driven by the top of the stirring shaft 502 through the lower bushing 603 connected below. This causes the lower branch pipe 602 connected to the swivel tank 601 to rotate along the arc groove guide plate 505 and against the inner wall of the desulfurization tower body 1 via the connected slip ring frame 606. Subsequently, the remaining liquid in the liquid supply end pipe 9 works together with the lower branch pipe 602 through the sub-pipes 607 and nozzles 608 connected to the upper branch pipe 610, filling the contact gap of the exhaust gas flow and improving the contact efficiency between the exhaust gas and the sprayed liquid of the nozzles 608, thereby allowing the exhaust gas to contact the spray pipe. After the liquid undergoes thorough desulfurization and produces gypsum precipitate, some liquid from the upper branch pipe 610 flows upward to the cross-flow pipe 701 and enters the ring pipe 613 through the cross-flow pipe 701. This causes the spray nozzle 614 connected to the ring pipe 613 to spray liquid onto the inner wall of the desulfurization tower 1, allowing the liquid to flow along the inner wall of the desulfurization tower 1 and reducing precipitate adhesion. Simultaneously, the stirring shaft 502 drives the rotating tank 601 to rotate synchronously, causing the nozzle 608 on the lower branch pipe 602 to dynamically fill the gaps in the waste gas flow following the arc groove guide plate 505, significantly improving gas-liquid contact efficiency. The liquid in the supply pipe 9 also... By forming a three-dimensional spray network with the upper branch pipe 610 and the lower branch pipe 602, the desulfurization effect is further enhanced and gypsum precipitate is generated. Part of the liquid in the upper branch pipe 610 enters the ring pipe 613 through the cross-flow pipe 701, so that the liquid sprayed out by the spray nozzle 614 flows along the inner wall of the desulfurization tower 1 to form a liquid film, which effectively reduces the adhesion of precipitates and scaling. Thus, without the need for additional power, dynamic tracking coverage of the spray layer, improvement of gas-liquid contact efficiency and online anti-scaling of the inner wall of the tower are achieved at the same time, which greatly enhances the operational reliability and comprehensive desulfurization performance of the desulfurization system.
[0027] The demisting and anti-clogging mechanism 7 includes a cross-flow pipe 701, a double branch pipe 702 fixedly connected to the top of the cross-flow pipe 701, a C-shaped pipe 704 fixedly connected to the end of the double branch pipe 702 away from the cross-flow pipe 701, multiple gap spray pipes 708 fixedly connected to the inner wall of the C-shaped pipe 704, a demisting frame 703 fixedly connected to the top of the inner side of the desulfurization tower body 1, a demisting device 705 installed inside the demisting frame 703, multiple horizontal spray pipes 706 fixedly connected to the outer surface of the double branch pipe 702, and a horizontal pipe frame 707 fixedly connected to the end of the horizontal spray pipe 706 away from the double branch pipe 702.
[0028] The intermittent nozzle 708 extends to the inside of the demister 705. The horizontal pipe frame 707 is located on the upper and lower sides of the demister frame 703. When the liquid in the supply pipe 9 enters the double branch pipe 702 through the connected cross-flow pipe 701, the double branch pipe 702 simultaneously flushes the upper and lower sides of the demister 705 inside the demister frame 703 through the nozzles opened on the surface of the connected spray port horizontal pipe 706. If intermittent spraying is required, a solenoid valve can be added to the connection path of the cross-flow pipe 701. This is existing technology and will not be elaborated further. At the same time, the double branch pipe 702 passes the remaining liquid into the C-shaped pipe 704, so that the C-shaped pipe 70... 4. Liquid is sprayed through the inner gap nozzle 708 to clean the side gap of the demister 705. The double branch pipe 702 simultaneously flushes the upper and lower sides of the demister 705 through the horizontal nozzle 706, eliminating blind spots in single-sided flushing. At the same time, the double branch pipe 702 introduces liquid into the C-shaped pipe 704, so that the gap nozzle 708 performs directional flushing of the side gap of the demister 705, specifically cleaning the dead corners of traditional flushing such as blade bends and barbs. This forms a three-dimensional flushing network that combines simultaneous upper and lower flushing with side gap flushing, significantly reducing the risk of scaling and clogging, and ensuring the long-term stable operation of the demister 705.
[0029] Working principle: The waste gas to be treated is input through the connected air supply port 8 on the side of the desulfurization tower body 1. The waste gas enters the interior of the connected inner cavity wall 501 from the air supply port 8, first filling the entire interior space of the inner cavity wall 501. When the stirring shaft 502 rotates under the drive of the bottom reduction motor, the stirring shaft 502 drives multiple stirring rods 504 to make circular motion through the connected stirring frame 503. The arc groove guide plate 505 connected to the stirring rods 504 makes the convex ring 506 that is attached to the outer wall of the inner cavity wall 501 make circular motion together. During this process, the connected guide plate 508 pushes the guide cone block 514 to be subjected to force, so that the guide cone block 514 slides along the side groove guide block 512 in the one-way cylinder 507. When the guide cone block 514 moves, the connected movable cone block 511 moves away from the side groove guide block 512. At this time, the waste gas in the inner cavity wall 501 passes around the movable cone block 511, and then moves through the side passage groove 513 on the side of the side groove guide block 512 to the side. Around the guide cone block 514, the gas flows through the air passage 509 on the side of the arc groove guide plate 505 and enters the bottom liquid pool of the desulfurization tower body 1. As the arc groove guide plate 505 slowly rotates with the stirring shaft 502, it controls four of the eight one-way cylinders 507 connected to the inner cavity wall 501 to be in an alternating gas supply state. The one-way cylinders 507 in different positions of the inner cavity wall 501 alternately supply gas, and the exhaust gas enters the bottom liquid pool of the desulfurization tower body 1 evenly, thereby reducing contact dead angles and making the exhaust gas and liquid contact evenly and improving contact efficiency. The stirring rod 504 and the arc groove guide plate 505 move to stir the sediment products falling at the bottom of the desulfurization tower body 1. At the same time, the arc groove guide plate 505 slides through the one-way cylinder 507 to scrape off the attached sediment. When the arc groove guide plate 505 moves away from the one-way cylinder 507, the movable cone block 511 will be reset under the action of the elastic spring and pop out from the inside of the one-way cylinder 507 to avoid blockage. When the external pump draws liquid from inside the desulfurization tower 1 to the supply pipe 9 through the pumping port 4, the liquid inside the supply pipe 9 enters the swivel tank 601 through the hinged pipe 604, then flows to the lower branch pipe 602 connected to the swivel tank 601, and then flows through the lower branch pipe 602 to the subdivision pipe 607 and the nozzle 608. At the same time, the swivel tank 601 is driven by the top of the stirring shaft 502 through the lower bushing 603 connected below, causing the lower branch pipe 602 connected to the swivel tank 601 to rotate along the arc groove guide plate 505 and against the inner wall of the desulfurization tower 1 through the connected slip ring frame 606. Subsequently, the liquid at the supply end... The remaining liquid in pipe 9 works together with the lower branch pipe 602 through the sub-pipe 607 and nozzle 608 connected to the upper branch pipe 610 to fill the gap in the contact between the exhaust gas flow and improve the contact efficiency between the exhaust gas and the spray liquid of nozzle 608. This allows the exhaust gas to be fully desulfurized after contacting the liquid in the spray pipe and to produce gypsum precipitate. At the same time, part of the liquid in the upper branch pipe 610 flows upward to the cross-flow pipe 701 and enters the ring pipe 613 through the cross-flow pipe 701. This causes the spray pipe 614 connected to the ring pipe 613 to spray the liquid to the inner wall of the desulfurization tower 1, so that the liquid flows along the inner wall of the desulfurization tower 1 and reduces the adhesion of precipitates. When the liquid in the supply pipe 9 enters the double branch pipe 702 through the connected cross-flow pipe 701, the double branch pipe 702 simultaneously flushes the upper and lower sides of the demister 705 inside the demister frame 703 through the nozzles opened on the surface of the connected spray pipe 706. If intermittent spraying is required, a solenoid valve can be added to the connection path of the cross-flow pipe 701. This is existing technology and will not be described in detail. At the same time, the double branch pipe 702 passes the remaining liquid into the C-shaped pipe 704, so that the C-shaped pipe 704 sprays liquid through the inner gap spray pipe 708 to spray and wash the side gap of the demister 705.
