Description

Technical Field

[0001] This invention relates to the field of gas separation and treatment technology, specifically to a desulfurization tower. Background Technology

[0002] Desulfurization towers are core environmental protection equipment in fields such as biogas purification, industrial waste gas treatment, and biomass gas purification. Their operational stability and treatment accuracy directly affect the compliance of exhaust gas emissions with standards and the service life of downstream gas-using equipment. In the widely used wet desulfurization process, the gas after desulfurization by spraying inside the tower usually carries desulfurizing agent droplets, reaction by-product particles, and trace amounts of incompletely removed sulfides. Therefore, the industry generally installs post-treatment units such as activated carbon adsorption layers and fiber filter layers at the gas outlet of the desulfurization tower for deep purification of the exhaust gas. This configuration has become a necessary link for the compliant operation of the desulfurization system. With the continuous improvement of industrial production requirements, the need for uninterrupted operation, ease of maintenance, and consistent purification effect of desulfurization systems, as key nodes in the production process, is becoming increasingly prominent.

[0003] However, the current post-adsorption filtration units of desulfurization towers have obvious technical shortcomings: on the one hand, the adsorption materials have a clear saturation failure cycle and must be cleaned or replaced regularly. Routine replacement operations require suspending the desulfurization tower exhaust process and closing upstream and downstream valves, which not only directly leads to production interruption but also increases the operation and maintenance costs and safety risks of system start-up and shutdown; on the other hand, some existing dual-path switching designs only realize simple path switching and lack a mandatory constraint mechanism on the maintenance status of adsorption components. In actual production, it is easy for operators to switch back to use without completing the cleaning of the saturated adsorption layer, which leads to fluctuations in exhaust purification effect and a significant increase in the risk of pollutant emissions exceeding standards, making it difficult to meet the production requirements of long-term continuous and stable operation. Summary of the Invention

[0004] The purpose of this invention is to provide a desulfurization tower that solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a desulfurization tower, comprising a desulfurization tower body, wherein an inlet pipe and an outlet pipe are provided on the desulfurization tower body, a sulfidation reaction device is provided inside the desulfurization tower body, a partition plate is fixedly connected to the inner wall of the outlet pipe, the inner cavity of the outlet pipe is divided into channel one and channel two by the partition plate, a positioning mounting plate is fixedly connected to the surface of the partition plate, and the surface of the positioning mounting plate has two openings respectively communicating with channel one and channel two, and rubber rings are embedded in the outer periphery of both openings;

[0006] The inner wall of the air outlet pipe is rotatably connected to a rotating shaft, and a sealing plate is fixedly connected to the shaft wall. The sealing plate is deflected by the passage switching component to selectively block the two openings. One-way valves are provided at the air outlets of both channel one and channel two. Adsorption components are slidably connected to the inner walls of both channel one and channel two. A maintenance box is fixedly connected to the top surface of the air outlet pipe. The maintenance box is equipped with two sets of switching constraint components to constrain the deflection state of the sealing plate by the cleaning state of the adsorption components, so as to ensure that both adsorption components are in a non-saturated state when they are working.

[0007] Optionally, the passage switching component includes a threaded rod rotatably connected to the inner wall of the maintenance box. Two threaded blocks are threadedly connected to the rod wall of the threaded rod. Both threaded blocks are slidably connected to the inner wall of the maintenance box. Side plate assemblies are fixedly connected to the bottom surfaces of both threaded blocks. U-shaped blocks are fixedly connected to the surfaces of both side plate assemblies. A mating plate assembly is vertically slidably connected to the inner walls of both U-shaped blocks. Four positioning mounting brackets are fixedly installed on the surfaces of the mating plate assemblies. A retaining shaft is fixedly installed on the rod walls of each of the four positioning mounting brackets. The shaft wall is rotatably connected to the inner wall of the maintenance box, and an incomplete gear is fixedly connected to the end of the shaft. The teeth of the incomplete gear are adapted to the dimensions of the four retaining shafts.

[0008] Optionally, the switching constraint component includes a sensor disposed on the inner wall of the adsorption assembly, and the inner wall of the air outlet pipe is provided with a sensing device corresponding to the sensor. It also includes a lateral restraint plate, which is fixedly connected to the inner wall of the maintenance box. The surface of the lateral restraint plate has a movable groove, which includes two parallel grooves and two inclined grooves. The inner wall of the movable groove is slidably connected to a limit pin, which is fixedly connected to the side of the mating plate assembly. The inner wall of the lateral restraint plate is slidably connected to two steering blocks. The surface of each of the two steering blocks is fixedly connected to a spring, and both springs are fixedly connected to the inner wall of the lateral restraint plate. The inner wall of each of the two steering blocks has an inner cavity, and the inner wall of each of the two inner cavities is slidably connected to a connecting sleeve rod. The rod walls of both connecting sleeve rods are slidably connected to the inner wall of the lateral restraint plate, and the ends of both connecting sleeve rods are fixedly connected to an electromagnetic actuator.

[0009] Optionally, when the adsorption assembly located on the same side as the sealing plate is being cleaned, the sensors and sensing devices on it will send control commands to the electromagnetic actuator to change the travel path of the limiting pin in the movable groove.

[0010] Optionally, it also includes two sets of stabilizing components, which are symmetrically arranged on both sides of the positioning mounting plate.

[0011] Optionally, the stabilizing component includes an inflatable airbag, the surface of which is fixedly connected to a connecting tube, and the surface of the adsorption assembly is fixedly connected to a squeezing plate. The connecting tube passes through the inner wall of the air outlet pipe and is fixedly connected to multiple squeezing airbags at its end.

[0012] Optionally, the position of the compression airbag is adapted to the position of the compression plate, and a handle is fixedly connected to the surface of the adsorption assembly.

[0013] Optionally, a drive motor is provided on the surface of the air outlet pipe, and the output end of the drive motor is fixedly connected to the end of the threaded rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: I. This invention utilizes two channels within the exhaust pipe, along with a deflectable sealing plate and a pathway switching component. When a single-sided adsorption component reaches saturation and requires cleaning or replacement, the pathway can be automatically switched via a drive motor. Once the channel containing the saturated adsorption component is sealed, offline maintenance is possible, while the clean adsorption component on the other side is immediately put into use. The entire switching process does not require shutting down the desulfurization tower or interrupting the exhaust flow for an extended period, completely avoiding the production interruption problem caused by the traditional desulfurization tower requiring shutdown for cleaning the post-filter layer, and significantly improving process continuity.

[0015] Meanwhile, the switching mechanism ensures that the rubber ring at the opening is fully pressed after each switch by the fit and constraint of the side plate assembly and the incomplete gear, effectively preventing gas leakage from the non-working channel and ensuring the airtightness and operational stability of the switching process.

[0016] Second, this invention establishes a forced operation logic where switching is impossible without cleaning the lateral constraint plate by constraining the path. Only when maintenance personnel pull out the saturated adsorption component for cleaning, triggering the corresponding signals from the sensors and sensing devices, can the path switching component properly drive the deflection of the sealing plate to complete the path switching. If the adsorption component is not pulled out for cleaning, the limit pin can only move along the upper parallel groove, locking the path switching operation. This mechanically avoids the problem of operators switching back to the previous state without cleaning the saturated adsorption layer due to time constraints, ensuring the exhaust gas treatment pass rate from the root and reducing human error risks in equipment operation and maintenance.

[0017] Third, through the linkage design of the adsorption component and the expansion airbag, the extrusion plate on the side wall of the adsorption component will simultaneously press and extrude the airbag during the process of the adsorption component being pulled out for cleaning. This causes the expansion airbag on the side of the positioning mounting plate to inflate and expand, forming a compression constraint on the side of the sealing plate that is on that side after switching. This further improves the fit between the sealing plate and the positioning mounting plate, enhances the compression and sealing effect of the sealing plate on the opening rubber ring, and extends the corresponding service life of the equipment.

Detailed Implementation

[0020] 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.

[0021] Example 1, please refer to Figures 1 to 9This invention provides a desulfurization tower, including a desulfurization tower body 1, an inlet pipe 2 and an outlet pipe 3 on the desulfurization tower body 1, and a sulfidation reaction device inside the desulfurization tower body 1. The gas to be desulfurized is introduced into the desulfurization tower body 1 from the inlet pipe 2 through the upstream conveying pipe. The specific desulfurization principle of the sulfidation reaction device inside the desulfurization tower body 1 is to spray water mist downwards, forming a countercurrent contact with the rising gas, thereby removing the sulfides in the gas. The treated gas is discharged from the outlet pipe 3 above.

[0022] Furthermore, a partition plate 4 is fixedly connected to the inner wall of the outlet pipe 3. The inner cavity of the outlet pipe 3 is divided into channel 1 5 and channel 2 6 by the partition plate 4. A positioning mounting plate 7 is fixedly connected to the surface of the partition plate 4. The surface of the positioning mounting plate 7 has two openings that communicate with channel 1 5 and channel 2 6 respectively. Rubber rings are embedded in the outer periphery of both openings. A rotating shaft 8 is rotatably connected to the inner wall of the outlet pipe 3. A sealing plate 9 is fixedly connected to the shaft wall of the rotating shaft 8. The sealing plate 9 is deflected by the passage switching component to selectively block the two openings. One-way valves are provided at the outlets of channel 1 5 and channel 2 6. Adsorption components 10 are slidably connected to the inner walls of channel 1 5 and channel 2 6. A maintenance box 11 is fixedly connected to the top surface of the outlet pipe 3. The two openings are used alternately. The gas passes through the adsorption component 10 and the adsorption component 10 adsorbs the residual particles in the gas. The treated gas is then introduced into the downstream process.

[0023] Furthermore, the passage switching component includes a threaded rod 12 rotatably connected to the inner wall of the maintenance box 11. A drive motor 34 is provided on the surface of the air outlet pipe 3. The output end of the drive motor 34 is fixedly connected to the end of the threaded rod 12. Two threaded blocks 13 are threadedly connected to the rod wall of the threaded rod 12. Both threaded blocks 13 are slidably connected to the inner wall of the maintenance box 11. Side plate assemblies 14 are fixedly connected to the bottom surface of both threaded blocks 13. U-shaped blocks 15 are fixedly connected to the surface of both side plate assemblies 14. The inner walls of both U-shaped blocks 15 are vertically slidably connected to a mating plate assembly 16. Four positioning mounting brackets 17 are fixedly installed on the surface of the mating plate assembly 16. A retaining shaft 18 is fixedly installed on the rod wall of each of the four positioning mounting brackets 17. The shaft wall of the rotating shaft 8 is rotatably connected to the inner wall of the maintenance box 11. An incomplete gear 19 is fixedly connected to the end of the rotating shaft 8. The teeth of the incomplete gear 19 are adapted to the size of the four retaining shafts 18.

[0024] More specifically, when the adsorption component 10 is saturated, the drive motor 34 can be activated to rotate the threaded rod 12, thereby causing the two threaded blocks 13 to move horizontally. Figure 9Taking the example shown, the side plate assembly 14, the mating plate assembly 16, and the two U-shaped blocks 15 will move synchronously. During the initial movement, the horizontal side of the incomplete gear 19 slides along the inner wall of the side plate assembly 14 and then disengages from it, instead engaging with the four locking shafts 18. Through the movement of the four locking shafts 18, the incomplete gear 19 is driven to rotate 180° until it is once again in contact with the inner wall of the side plate assembly 14. This completes one horizontal movement of the U-shaped blocks 15, driving the incomplete gear 19 to rotate 180°. Through the synchronous transmission of the rotating shaft 8, the sealing plate 9 can be deflected from one opening to another, and the rubber ring around the opening is squeezed. This completes the switching process from channel 1 5 to channel 2 6. The desulfurized gas is discharged from channel 2 6, at which point the adsorption component 10 in channel 1 5 can be processed.

[0025] It is worth noting that the saturation identification process of the adsorption component 10 can be collected by the built-in sensor, and the standard usage time can also be preset. Furthermore, the adsorption component 10 includes an outer layer and an inner layer. If the inner layer is a consumable material such as activated carbon, it can be replaced by personnel. During the aforementioned process, the side plate assembly 14 ensures that when the U-shaped block 15 does not move, the side plate assembly 14 is in contact with the horizontal side of the incomplete gear 19, meaning the incomplete gear 19 always remains in a non-rotating state. Therefore, after each switch, based on the requirement that the two remain in contact, the switching process of the sealing plate 9 can effectively block the opening. Combined with the compression process of the rubber ring, this ensures that no gas leaks from the non-working opening.

[0026] In addition, the above design can avoid long-term desulfurization shutdowns. When one adsorption component 10 is being treated, the use of the other is not affected, thus improving the overall efficiency of the process.

[0027] Example 2, based on the above examples: Please see Figures 5 to 10 The maintenance box 11 is equipped with two sets of switching constraint components to constrain the deflection state of the sealing plate 9 based on the cleaning state of the adsorption assembly 10, ensuring that both adsorption assemblies 10 are in a non-saturated state during operation. The switching constraint components include a sensor 20 installed on the inner wall of the adsorption assembly 10, and a sensing device corresponding to the sensor 20 installed on the inner wall of the exhaust pipe 3. A handle is fixedly connected to the surface of the adsorption assembly 10. To process the adsorption assembly 10, simply grasp the handle and pull it out. This pulling process does not completely remove it from the exhaust pipe 3, but rather exposes the central area of ​​the adsorption assembly 10 outside the exhaust pipe 3. After pulling out, the sensor 20 on the adsorption assembly will correspond to the sensing device on the inner wall of the exhaust pipe 3.

[0028] Furthermore, it also includes a lateral restraint plate 21, which is fixedly connected to the inner wall of the maintenance box 11. The surface of the lateral restraint plate 21 is provided with a movable groove 22, which includes two parallel grooves 23 and two inclined grooves 24. The inner wall of the movable groove 22 is slidably connected to a limit pin 25, which is fixedly connected to the side of the mating plate assembly 16. The inner wall of the lateral restraint plate 21 is slidably connected to two steering blocks 26, and the surface of each steering block 26 is fixedly connected to a spring 27. Both springs 27 are fixedly connected to the inner wall of the lateral restraint plate 21. The inner wall of each steering block 26 is provided with an inner cavity 28, and the inner wall of each inner cavity 28 is slidably connected to a connecting sleeve rod 29. The rod wall of each connecting sleeve rod 29 is slidably connected to the inner wall of the lateral restraint plate 21. The ends of each connecting sleeve rod 29 are fixedly connected to an electromagnetic actuator 30.

[0029] Specifically, during the translation process in conjunction with plate 16, the limiting pin 25 will also move synchronously. Figure 9 As shown in the example, the limiting pin 25 will slide along the inner wall of the movable groove 22. When the adsorption assembly 10, which is on the same side as the sealing plate 9, is being cleaned, the sensor 20 on it corresponds to the sensing device and sends a control command to the electromagnetic actuator 30. At this time, the electromagnetic actuator 30 drives the connecting sleeve 29 to retract and pulls the steering block 26 into the inner wall of the lateral constraint plate 21, that is, it disengages from the inclined groove 24. At this time, as the limiting pin 25 moves from one end to the other, it will be affected by gravity and will move preferentially from the inner wall of the inclined groove 24. That is, its travel path is inclined groove 24, the lower parallel groove 23, and inclined groove 24. During this movement, the incomplete gear 19 and the four locking shafts 18 are on the same horizontal plane, that is, the two can cooperate with each other to drive the incomplete gear 19 to rotate, thereby completing the switching process between channel 1 5 and channel 2 6.

[0030] Conversely, if the adsorption component 10 is not pulled out and cleaned, the steering block 26 is in the inclined groove 24. When the limiting pin 25 needs to move from one end to the other, it will move from the upper parallel groove 23. That is, the travel path of the limiting pin 25 in the movable groove 22 will only be the upper parallel groove 23. Since the vertical height of the upper limiting pin 25 no longer changes along the movement path, the mating plate assembly 16 will not slide downwards during the movement of the U-shaped block 15. That is, the locking shaft 18 is not on the same horizontal plane as the incomplete gear 19. Instead, the mating plate assembly 16 and the incomplete gear 19 are on the same plane. At this time, the mating plate assembly 16 and the side plate assemblies 14 on both sides will cooperate, preventing the incomplete gear 19 from deflecting, that is, preventing the opening from being switched.

[0031] Through the above process, the operation logic of switching the opening can only be carried out after the adsorption component 10 has been treated. This avoids the situation where the adsorption component 10 is forgotten to be treated due to human negligence or consideration of the desulfurization progress. Compared with some traditional methods that directly switch the gas outlet path through the control center, this measure ensures the qualification rate of gas treatment and makes the operation process more standardized.

[0032] It is also worth noting that, as can be seen from the above, when the saturated adsorption component 10 is not processed, starting the drive motor 34 will not cause the incomplete gear 19 to rotate. A monitoring program corresponding to the connection end of the rotating shaft 8 can be set in the drive motor 34. When the drive shaft of the drive motor 34 is working, if the rotating shaft 8 is not detected to be working, the drive motor 34 can automatically reset.

[0033] Example 3, based on the above examples: Please see Figure 5 and Figure 6 It also includes two sets of stabilizing components, which are symmetrically arranged on both sides of the positioning mounting plate 7. The stabilizing components include an inflatable airbag 31, with a connecting pipe 32 fixedly connected to the surface of the inflatable airbag 31, and a squeezing plate 33 fixedly connected to the surface of the adsorption assembly 10. The connecting pipe 32 passes through the inner wall of the air outlet pipe 3 and has multiple squeezing airbags fixedly connected to its end. The position of the squeezing airbags is adapted to the position of the squeezing plate 33.

[0034] Furthermore, during the process of pulling out the adsorption component 10, the compression plate 33 will move synchronously until it is fully pulled out. After that, the compression plate 33 will compress multiple compression airbags, thereby causing the expansion airbags 31 to expand through the connecting pipe 32, blocking the side of the sealing plate 9 on that side. This improves the safety of the connection between the sealing plate 9 and the rotating shaft 8, makes the sealing plate 9 fit the positioning mounting plate 7 more closely, and allows the sealing plate 9 to better compress the rubber ring.

[0035] It should be emphasized that only three sets of compression airbags are shown in the figure, which does not mean that there are only three sets of compression airbags. This process can be added as needed to ensure that the inflatable airbag 31 is in an inflated state and compresses and constrains the side of the sealing plate 9.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
