Description

Technical Field

[0001] This invention relates to the field of chemical equipment technology, specifically to a quick-installation device and method for modular ammonia stripping tower trays, and an ammonia stripping tower system. Background Technology

[0002] Ammonia stripping towers, used in industries such as chemical, coking, and fertilizer processing for ammonia nitrogen removal and recovery, rely on internal trays as key structural components that facilitate vapor-liquid two-phase contact and achieve mass and heat transfer. During actual operation, due to the complexity of the materials being processed, the tray surfaces are prone to scaling, crystallization, or the adhesion of impurities such as tar. This leads to decreased mass transfer efficiency, increased pressure drop, and in severe cases, even tray blockage, affecting the stable operation and capacity of the entire production system.

[0003] In related technologies, the maintenance of ammonia stripping tower trays faces two main challenges. First, traditional trays are often fixed to the tower body by welding or numerous locking components, making tray replacement and maintenance inconvenient. Maintenance requires system shutdown, depressurization, purging, and cooling, necessitating personnel to enter the confined space inside the tower for disassembly. This process is not only time-consuming, leading to production losses, but also poses high risks due to high temperatures, toxic and hazardous substances, and confined space operations. Second, scaling is difficult to clean. Whether through manual scrubbing, high-pressure water jet rinsing, or cleaning methods using media such as sand or hot ammonia, secondary contaminants must be treated, making it difficult to completely remove stubborn scaling, and potentially damaging the trays themselves. Summary of the Invention

[0004] In view of this, the present invention provides a quick-installation device and method for modular ammonia stripping tower trays to solve the problems mentioned in the background art.

[0005] In a first aspect, the present invention provides a quick-assembly device for modular ammonia stripping tower trays, comprising: The tower body has at least one horizontally movable tower tray inside. A maintenance passage is provided on the side wall of the tower body, and the maintenance passage is equipped with an openable and closable disassembly cover; A processing cover is fixedly installed on the outer wall of the tower body and communicates with the maintenance channel. The processing cover has a processing chamber inside for accommodating the tower tray. And a push-out mechanism, which is disposed on the tower body and located on the side of the tower tray away from the maintenance channel, the push-out mechanism including a pusher block adapted to contact the tower tray and a drive member for driving the pusher block to move along the moving direction of the tower tray; When the disassembly cover is opened, the driving component drives the pusher block to push the tray into the processing chamber of the processing cover through the maintenance channel.

[0006] Beneficial Effects: The quick-installation device integrates horizontally movable trays, side wall maintenance channels, external processing covers, and a built-in ejection mechanism. The target tray can be removed from the tower body via the side wall maintenance channels and the ejection mechanism for rapid cleaning and maintenance, reducing production downtime and capacity loss. It also avoids operators entering confined spaces with toxic, hazardous, or high-temperature environments for high-risk operations, eliminating potential personal safety hazards. The pusher block and drive mechanism in the ejection mechanism quickly and smoothly remove the tray from the tower body, significantly shortening operation time and reducing labor intensity compared to traditional manual disassembly and handling. The quick-installation device provided in this application facilitates offline cleaning, inspection, repair, and replacement of trays.

[0007] In some embodiments, the driving component is an electric push rod, the mounting end of which is fixed to the outer wall of the tower body via a fixing frame and a connecting block, and the pushing end of which is fixedly connected to the pushing block.

[0008] Beneficial effects: The electric actuator provides a smooth and controllable linear thrust, ensuring accurate positioning and stable movement of the trays during transport, preventing impact damage to the trays or the tower body. Furthermore, the electric actuator is easily integrated with the control system, enabling quick push-out or reset operations, thus improving operational convenience and automation. Fixed to the outer wall of the tower via a mounting bracket and connecting block, it does not occupy valuable internal space and is securely installed, able to withstand the reaction force when the tray is pushed out.

[0009] In some embodiments, the disassembly cover is rotatably connected to the outer wall of the tower body via a hinge and a rotating component, and a sealing ring is fixed to the inner edge of the disassembly cover; when the disassembly cover and the tower body are in a closed connection state, the sealing ring is in contact with and sealed to the inner wall of the tower body.

[0010] Beneficial effects: The combination of hinges and rotating parts allows the disassembly cover to be easily opened and closed, meeting usage requirements. The sealing ring inside the disassembly cover fits tightly against the inner wall of the tower when the cover is closed, effectively preventing leakage of process gas from the maintenance channel, ensuring the sealing and safety of the ammonia stripping tower during normal operation, and avoiding media loss.

[0011] In some embodiments, a filter cleaning brush is provided in the processing chamber of the processing cover, and the tray is disposed above the filter cleaning brush; At least one vibration component is connected below the filter cleaning brush, and the vibration component is used to vibrate the filter cleaning brush and the tray placed above it.

[0012] Beneficial effects: After the trays are pushed into the processing chamber by the ejector mechanism, cleaning and maintenance can be performed within the chamber. For stubborn scale, the vibration assembly applies physical vibration to the trays to effectively shake off and loosen crystalline or adhered tar-like stubborn dirt. Combined with the auxiliary scraping action of the filter cleaning brush, the cleaning effect on the trays is improved. The cleaned dirt falls to the bottom of the processing chamber and is intercepted by the filter cleaning brush, facilitating centralized collection and treatment and avoiding secondary pollution. Moreover, this operating mode causes minimal damage to the trays themselves.

[0013] In some embodiments, the vibration assembly includes: The swing rod is hinged to the inner wall of the processing cover via a rotating rod; A buffer spring is disposed below the swing rod, and the buffer spring is connected between the swing rod and the inner wall of the processing cover; A push ball is located at the end of the swing arm, and the filter cleaning brush is located above the push ball or connected to the push ball; A vibration block is disposed below the swing rod, the vibration block being used to periodically contact the swing rod to cause the swing rod to swing; the vibration block and the buffer spring are disposed at intervals.

[0014] Beneficial effects: The periodic contact between the vibrating block and the swing arm causes the swing arm to oscillate, and the vibration energy is transferred to the filter brush and tray via the pushing ball, thus improving cleaning efficiency. The buffer spring provides a restoring force and absorbs some of the impact during the vibration gap, ensuring that the vibration force is reasonable and avoiding excessive impact on the filter brush and tray, preventing damage to the tray itself. Using the pushing ball at the end of the swing arm as the force transmission point reduces the contact area, lowers friction, and makes the vibration transmission more direct with less energy loss.

[0015] In some embodiments, the vibrating block is configured as an eccentric wheel or a cam, the processing cover is provided with a motor, and the vibrating block is connected to the drive end of the motor via a rotating shaft.

[0016] Beneficial effects: By controlling the motor speed, the rotational speed of the eccentric wheel or cam can be easily adjusted, thereby changing the frequency and amplitude of vibration. This adapts to different types and degrees of scale buildup, achieving optimal cleaning results. Furthermore, the motor-driven operation is smooth and provides continuous power, and facilitates automatic start-stop control, meeting the automation requirements of the entire quick-installation maintenance process.

[0017] In some embodiments, at least one mounting groove is provided on the inner wall of the tower body, a second fixing rod is fixedly connected in the mounting groove, a movable material transfer wheel is rotatably sleeved on the second fixing rod, the movable material transfer wheel is disposed at the bottom of the tower tray, and the rotation axis of the movable material transfer wheel is perpendicular to the movement direction of the tower tray.

[0018] Beneficial effects: Converting the sliding friction between the tray and the inner wall of the tower into rolling friction reduces wear and scratches on the bottom of the tray and the inner wall of the tower. This helps to reduce the driving force required by the ejection mechanism to move the tray, reduces the power requirements of the drive components, makes the movement, ejection or resetting of the tray smoother, and helps to ensure the integrity of the sealing surface between the tray and the inner wall of the tower.

[0019] In some embodiments, the tower body is formed by splicing together at least two tower sections using a detachable structure; each tower section is provided with at least one set of corresponding tower trays, maintenance channels, processing covers, and ejection mechanisms. The detachable structure includes a first split plate and a second split plate respectively fixed to the end face of adjacent tower sections, and a locking member connecting the first split plate and the second split plate; The tower body is fixedly provided with a base at its bottom, and multiple support rods are fixedly connected below the base.

[0020] Beneficial effects: The tower body adopts a detachable segmented design, with each segment capable of being independently equipped with a quick-installation system, improving the processing capacity of the ammonia stripping tower; it allows for segmented isolation maintenance, meaning that when a tray in a particular segment requires maintenance, only the material flow in that segment can be stopped while other segments continue operating, minimizing the impact of maintaining a single segment on production; the detachable design also facilitates transportation and on-site installation. The base and support rods provide a stable support foundation for the entire tower body, ensuring overall rigidity and safety during operation and tray removal.

[0021] In some embodiments, the system further includes a combined reactor disposed inside the tower body and located between the trays of two adjacent layers; the combined reactor has an inlet pipe connected to its inlet end and a drain pipe connected to its outlet end, with the inlet pipe and the drain pipe extending outwards from the tower body, respectively.

[0022] Beneficial effects: By installing a combined reactor between the two trays, the combined reactor can be used to simultaneously carry out other chemical reactions in the ammonia stripping process, such as neutralization and catalytic decomposition, enabling targeted treatment of complex impurities or specific components and improving the processing efficiency of the unit. The combined reactor can be connected to external systems through inlet and outlet pipes, making the ammonia stripping tower a composite integrated platform.

[0023] Secondly, the present invention also provides a quick-assembly method, wherein the quick-assembly method employs the aforementioned quick-assembly device for the modular ammonia stripping tower trays, and the quick-assembly method includes the following steps: Stop supplying material to the section of the tower where the target tray is located, and open the corresponding disassembly cover of the target tray; The drive unit of the ejection mechanism is activated to drive the pusher block to push the target tray horizontally, so that it moves out of the tower body through the maintenance channel and into the processing chamber of the processing cover; The trays are cleaned, inspected, or replaced within the processing chamber. After the operation is completed, the target tray is reset and pushed back into the tower body by reversing the drive mechanism or using external tools, and the cover is closed and locked.

[0024] Beneficial effects: The quick-installation method first partially isolates the target tower section and opens the maintenance passage; then, the tray is smoothly moved to the external processing chamber through the built-in ejection mechanism; offline cleaning, inspection, or replacement is performed here; after completion, it is reset and the maintenance passage is closed, thus achieving rapid replacement of the ammonia stripping tower tray. The quick-installation method eliminates the need for operators to enter the tower, significantly shortening maintenance time, avoiding high-risk operations, and improving maintenance efficiency and safety.

[0025] Thirdly, the present invention also provides an ammonia stripping tower system, comprising: A quick-assembly device for modular ammonia stripping tower trays, wherein the quick-assembly device is provided with at least two sets of tower bodies arranged in parallel; And a switching valve group, the switching valve group including a first switching valve and a second switching valve, the upper end interfaces of all the tower bodies are connected to the first switching valve, and the lower end interfaces of all the tower bodies are connected to the second switching valve.

[0026] Beneficial effects: The ammonia stripping tower system connects multiple towers in parallel and is equipped with switching valve groups. When any tower or its trays require maintenance or cleaning, the tower can be isolated by the switching valve group, while the remaining towers continue to operate normally, achieving continuous operation without stopping the machine and reducing interference with production. Maintenance work can be carried out without affecting production, and the maintenance and cleaning process is safer, more orderly, and more controllable. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0031] The technical objective of this embodiment is to provide a highly integrated tower tray maintenance solution. Specifically, by designing the tower tray as a horizontally movable module and incorporating a maintenance channel on the side wall of the tower body, along with an external processing cover and a built-in ejection mechanism, a rapid transfer path for the tower tray is formed from the working position to the external maintenance station. When maintenance is required, simply isolate the corresponding tower section, open the maintenance channel, and activate the ejection mechanism to smoothly and accurately move the target tower tray out of the tower body and into the isolated processing chamber for offline operation. The entire process requires no personnel to enter the tower, thus changing the traditional maintenance model.

[0032] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, in a first aspect, a quick-installation device for modular ammonia stripping tower trays is provided, such as... Figures 1 to 4 As shown, the quick-installation device includes a tower body 1, a maintenance channel, a processing cover 6, and an ejection mechanism. The top of the tower body 1 is provided with an exhaust pipe 2 for discharging air. The tower body 1 has at least one horizontally movable tray 13 inside. The maintenance channel is located on the side wall of the tower body 1 and has an openable and closable disassembly cover 3. The processing cover 6 is fixedly installed on the outer wall of the tower body 1 and communicates with the maintenance channel. The processing cover 6 forms a processing chamber for accommodating the tray 13. The ejection mechanism is installed on the tower body 1 and located on the side of the tray 13 away from the maintenance channel. The ejection mechanism includes a pusher block 28 adapted to contact the tray 13 and a drive component that drives the pusher block 28 to move along the moving direction of the tray 13. When the disassembly cover 3 is opened, the drive component drives the pusher block 28 to push the tray 13 into the processing chamber of the processing cover 6 through the maintenance channel.

[0034] The quick-installation device provided in this embodiment integrates a horizontally movable tray 13, a maintenance channel on the side wall, an external processing cover 6, and a built-in ejection mechanism. The target tray 13 can be moved out of the tower body 1 via the side wall maintenance channel and the ejection mechanism for rapid cleaning and maintenance, reducing production interruption time caused by maintenance and minimizing capacity loss. It also avoids operators entering confined spaces with toxic, harmful, and high-temperature conditions for high-risk operations, eliminating potential safety hazards.

[0035] The pusher block 28 and drive unit combination in the ejection mechanism can quickly and smoothly remove the tray 13 from the tower body 1. Compared with traditional manual disassembly and handling, the operation time is greatly shortened and the labor intensity is reduced. The quick-installation device provided by this application facilitates the offline cleaning, inspection, maintenance and replacement of the tray 13.

[0036] In a specific embodiment, the driving component is an electric push rod 11. The mounting end of the electric push rod 11 is fixed to the outer wall of the tower body 1 via a fixing bracket 32 ​​and a connecting block 14, and the pushing end of the electric push rod 11 is fixedly connected to the pusher block 28. The electric push rod 11 provides a smooth and controllable linear thrust, ensuring accurate positioning and stable movement of the tower tray 13 during movement, avoiding impact damage to the tower tray 13 or the tower body 1. Furthermore, the electric push rod 11 is easy to integrate with the control system, enabling quick push-out or reset operations, thus improving operational convenience and automation. Fixed to the outer wall of the tower via the fixing bracket 32 ​​and connecting block 14, it does not occupy effective space inside the tower, ensuring smooth flow within the tower, and its secure installation can withstand the reaction force when the tower tray 13 is pushed out.

[0037] In a specific embodiment, the connection between the pusher block 28 and the tray 13 is as follows: the pusher block 28 and the tray 13 are detachably snap-fitted together. The pusher block 28 has a snap-fit ​​groove on the wall facing the tray 13, and the tray 13 has a snap-fit ​​block on the wall facing the pusher block 28. The pusher block 28 and the tray 13 are connected by snapping together through the snap-fit ​​groove and the snap-fit ​​block. During the process of the push-out mechanism pushing out or resetting the tray 13, the pusher block 28 drives the tray 13 to move horizontally.

[0038] In another specific embodiment, the wall surface of the pusher block 28 facing the tray 13 is set as a semi-circular arc surface. When the pusher mechanism pushes out the tray 13, this semi-circular arc surface contacts the outer wall surface of the tray 13 to transmit force. When the tray 13 needs to be reset, the pusher mechanism is reset first, and then the tray 13 is moved horizontally to reset by external tools.

[0039] In the specific options, the electric actuator 11 needs to comprehensively consider the thrust, stroke, speed, and protection level. The thrust must be calculated based on the mass of the tray 13, the friction with the tower wall, and the potential scaling and adhesion forces, with a certain safety margin to ensure reliable ejection of the tray 13 under any operating condition. The stroke must be slightly greater than the distance required for the tray 13 to fully move from the working position into the processing chamber; the speed should be adjustable, combining rapid ejection and reset with slow, precise positioning, with the ejection or reset speed set to 10-50 mm / s. Due to the chemical environment, the enclosure protection level should be no less than IP65, and the motor 21 insulation class should be F or higher to withstand potentially humid and corrosive atmospheres.

[0040] In a specific embodiment, a first fixing rod 10 is fixedly connected to the outer wall of the tower body 1, and the mounting end of the electric push rod 11 is fixedly connected to the first fixing rod 10.

[0041] In specific embodiments, such as Figure 2 and Figure 3As shown, the disassembly cover 3 is rotatably connected to the outer wall of the tower body 1 via hinge 4 and rotating component 5. A sealing ring 26 is fixed to the inner edge of the disassembly cover 3. When the disassembly cover 3 is in the closed connection state with the tower body 1, the sealing ring 26 is in close contact with the inner wall of the tower body 1. The combination of hinge 4 and rotating component 5 allows the disassembly cover 3 to be easily rotated open and closed, meeting usage requirements. When the disassembly cover 3 is closed, the sealing ring 26 on the inner side of the disassembly cover 3 can fit tightly against the inner wall of the tower, effectively preventing the process gas inside the tower from leaking from the maintenance channel, ensuring the sealing and safety of the ammonia stripping tower during normal operation, and avoiding media loss.

[0042] In a specific embodiment, the hinge 4 and the rotating part 5 can be configured as heavy-duty door hinges. A locking handle is provided at the location of the heavy-duty door hinge. The locking handle is used to lock the heavy-duty door hinge to lock the disassembly cover 3 and the tower body 1.

[0043] In specific embodiments, such as Figure 5 As shown, at least one mounting groove 25 is provided on the inner wall of the tower body 1. A second fixing rod 23 is fixedly connected in the mounting groove 25. A movable material transfer wheel 22 is rotatably sleeved on the second fixing rod 23. The movable material transfer wheel 22 is located at the bottom of the tray 13, and the rotation axis of the movable material transfer wheel 22 is perpendicular to the movement direction of the tray 13. This converts the sliding friction between the tray 13 and the inner wall of the tower body 1 into rolling friction, reducing wear and scratches between the bottom of the tray 13 and the inner wall of the tower body 1. This helps to reduce the driving force required by the ejection mechanism to move the tray 13, reduces the power requirements of the driving components, makes the movement, ejection, or resetting of the tray 13 smoother, and helps to ensure the integrity of the sealing surface between the tray 13 and the inner wall of the tower body 1.

[0044] In specific embodiments, such as Figure 5 As shown, a removal groove 24 is provided on the inner wall of the tower body 1. The removal groove 24 is used for moving the tower tray 13 away from the inner cavity of the tower body 1 or returning it to the inner cavity of the tower body 1.

[0045] In specific embodiments, such as Figure 1 As shown, a filter cleaning brush 12 is provided in the processing chamber of the processing cover 6, and a tray 13 is disposed above the filter cleaning brush 12; at least one vibration component is connected below the filter cleaning brush 12, and the vibration component is used to vibrate the filter cleaning brush 12 and the tray 13 disposed above it.

[0046] After the tray 13 is pushed into the processing chamber by the ejector mechanism, cleaning and maintenance can be performed within the processing chamber. For stubborn scale, the vibration assembly can apply physical vibration to the tray 13 to effectively shake off and loosen crystalline or adhered tar-like stubborn dirt. Combined with the auxiliary scraping action of the filter cleaning brush 12, the cleaning effect of the tray 13 is improved. The cleaned dirt will fall to the bottom of the processing chamber and be intercepted by the filter cleaning brush 12, which can be easily collected and processed, avoiding secondary pollution caused by dirt splashing. Moreover, this non-contact or flexible contact operation mode also minimizes damage to the tray 13 itself, which helps to extend the service life of the tray 13.

[0047] In a specific embodiment, two vibration components are provided, and the two vibration components are placed at an interval below the filter cleaning brush 12.

[0048] In specific embodiments, such as Figure 6 As shown, the vibration assembly includes a swing rod 15, a buffer spring 17, a push ball 18, and a vibration block 19. The swing rod 15 is hinged to the inner wall of the processing cover 6 via a rotating rod 16. The buffer spring 17 is located below the swing rod 15 and is connected between the swing rod 15 and the inner wall of the processing cover 6. The push ball 18 is located at the end of the swing rod 15, and the filter cleaning brush 12 is located above or connected to the push ball 18. The vibration block 19 is located below the swing rod 15 and is used to periodically contact the swing rod 15 to make the swing rod 15 swing. The vibration block 19 and the buffer spring 17 are spaced apart.

[0049] The vibrating block 19 periodically contacts and lifts the swing rod 15, causing it to swing back and forth around the hinge point. Vibrational energy is then transferred to the filter brush 12 and tray 13 via the pushing ball 18, improving the cleaning efficiency of scale removal. The buffer spring 17 provides a restoring force and absorbs some of the impact during the vibration gap, ensuring the vibration has appropriate force and elasticity, preventing excessive impact on the filter brush 12 and tray 13 and avoiding damage to the tray 13 itself. Using the pushing ball 18 at the end of the swing rod 15 as the force transmission point reduces the contact area, lowers friction, and makes vibration transmission more direct with less energy loss.

[0050] In specific embodiments, such as Figure 6As shown, the vibrating block 19 is configured as an eccentric wheel or cam, and the treatment cover 6 is equipped with a motor 21. The vibrating block 19 is connected to the drive end of the motor 21 via a rotating shaft 20. By controlling the rotation speed of the motor 21, the rotation speed of the eccentric wheel or cam can be easily adjusted, thereby changing the frequency and amplitude of the vibration. This allows for adaptation to different types and degrees of scaling to achieve the best cleaning effect. Furthermore, the motor 21 drive provides smooth operation and continuous power, and facilitates automatic start-stop control, meeting the automation requirements of the entire quick-installation maintenance operation.

[0051] In specific structural embodiments, such as Figure 6 As shown, two push balls 18 are symmetrically fixedly connected to both sides of the swing rod 15, and a rotating rod 16 is connected to the middle section of the swing rod 15. A buffer spring 17 is connected to one end of the swing rod 15 at a position offset from the middle section. With this design, when the vibrating block 19 periodically impacts a point on the swing rod 15 located between the connection point of the buffer spring 17 and one of the push balls 18, the spring connection point's offset from the middle section creates an asymmetrical lever with dynamically changing lengths of the power arm and resistance arm. When the vibrating block 19 impacts the swing rod 15, the swing rod 15 not only swings up and down around the hinge point but also experiences slight torsional deformation due to the asymmetrical constraint caused by the spring's offset connection. This deformation prevents the two symmetrical push balls 18 from moving completely synchronously and in phase, resulting in a slight phase or amplitude difference. This complex motion pattern, transmitted to the tower plate 13, creates a composite vibration with vertical impact, weak horizontal shearing, and torsional effects. This multi-directional vibration helps to break up viscoelastic tar or interwoven crystalline dirt, disrupt the binding force, and improve the vibration cleaning efficiency of the vibration assembly on the tray 13.

[0052] In an optional embodiment, as an enhancement and supplement to the cleaning operation of the processing chamber, a spray cleaning assembly (not shown in the figure) is integrated on the top or side wall of the processing cover 6. The spray cleaning assembly includes an annular spray pipe, high-pressure nozzles, a cleaning fluid supply pump, and a recovery tank. The annular spray pipe is arranged around the upper part of the processing chamber, and multiple high-pressure nozzles are distributed on it facing the tray 13. The cleaning fluid supply pump is connected to an external cleaning fluid storage tank and the annular spray pipe through a pipeline. The bottom of the processing chamber can be designed as a funnel and connected to the recovery tank. When the tray 13 enters the processing chamber, the spray system can be activated first to uniformly spray heated chemical cleaning fluid onto the surface of the tray 13 to soak and soften tar and crystals. Subsequently or simultaneously, the vibration assembly is activated. Under the synergy of fluid flushing and chemical action, physical vibration can more efficiently remove dirt. The waste liquid after cleaning flows into the bottom recovery tank for centralized treatment or filtration and recycling.

[0053] In an optional embodiment, to ensure the precise movement trajectory of the tray 13 during ejection and resetting, and to guarantee its sealing performance while operating within the tower, the quick-installation device further includes a guiding and sealing system (not shown in the figure). The guiding and sealing system includes guide strips disposed on both sides of the tray 13 and corresponding guide grooves disposed on the inner wall of the tower body 1. The sliding engagement between the guide strips and guide grooves ensures that the tray 13 moves only linearly in the horizontal direction of movement; the engagement of the guide strips and guide grooves reduces the risk of deflection or jamming of the tray 13 during movement, allowing the thrust of the ejection mechanism to overcome frictional forces in the direction of movement. The guiding and sealing system also includes an elastic sealing ring; the elastic sealing ring is configured as a graphite-reinforced polytetrafluoroethylene ring. This elastic sealing ring is embedded on the outer periphery of the tray 13. When the tray 13 is in the working position, the elastic sealing ring, under the weight of the tray 13 and the internal pressure of the system, tightly adheres to the sealing surface of the inner wall of the tower body 1. The guiding and sealing system also includes a lip seal ring; the lip seal ring is set at the opening of the maintenance channel, and it forms a secondary seal with the edge sealing ring of the tray 13. The sealing design achieves precise guidance of the movement of the tray 13 and reliable sealing during operation.

[0054] In specific structural embodiments, such as Figure 1 and Figure 2 As shown, the tower body 1 is formed by splicing together at least two tower sections through a detachable structure; each tower section is provided with at least one set of corresponding tower trays 13, maintenance channels, processing covers 6 and ejection mechanisms; the detachable structure includes a first split plate 7 and a second split plate 8 respectively fixed to the end face of adjacent tower sections, and a locking member 9 connecting the first split plate 7 and the second split plate 8.

[0055] Tower 1 adopts a detachable tower section splicing design, and each tower section can be independently equipped with a quick-installation system to improve the processing capacity of the ammonia stripping tower; the detachable splicing design facilitates transportation and on-site installation.

[0056] In specific embodiments, such as Figure 1 As shown, within a tower section, multiple layers of horizontally removable trays 13 are arranged vertically. Each tray 13 has a set of lateral maintenance channels, an external treatment cover 6, and a built-in ejection mechanism. Multiple ejection mechanisms for the same tower section can be jointly installed on the outer wall of the tower section via brackets.

[0057] In specific embodiments, such as Figure 1 As shown, a base 30 is fixedly installed at the bottom of the tower body 1, and multiple support rods 31 are fixedly connected below the base 30. The base 30 and the support rods 31 provide a stable support foundation for the entire tower body 1, ensuring the overall rigidity and safety of the equipment during operation and when the tower tray 13 is pushed out.

[0058] In specific embodiments, such as Figure 7 and Figure 8As shown, the quick-assembly device also includes a combined reactor 27, which is located inside the tower body 1 and between two adjacent trays 13. The combined reactor 27 has an inlet pipe 29 connected to its inlet end and a drain pipe 33 connected to its outlet end. Both the inlet pipe 29 and the drain pipe 33 extend outwards to the outside of the tower body 1. The combined reactor 27, positioned between the two trays 13, can be used to simultaneously perform other chemical reactions in the ammonia stripping process, such as neutralization and catalytic decomposition, enabling targeted treatment of complex impurities or specific components and improving the device's processing efficiency. The combined reactor 27 can be connected to an external system via the inlet pipe 29 and the drain pipe 33, allowing the ammonia stripping tower to function as a composite integrated platform.

[0059] According to an embodiment of the present invention, in a second aspect, a quick-assembly method for a modular ammonia stripping tower tray quick-assembly device is also provided, the quick-assembly method comprising the following steps: Stop supplying material to the section of the tower where the target tray 13 is located, and open the disassembly cover 3 corresponding to the target tray 13; The drive unit of the ejection mechanism is activated to drive the pusher block 28 to push the target tray 13 horizontally, so that it moves out of the tower body 1 through the maintenance channel and into the processing chamber of the processing cover 6. The tray 13 is cleaned, inspected, or replaced within the processing chamber; After the operation is completed, the target tray 13 is reset and pushed back into the tower body 1 by reversing the action of the drive component or by using an external tool, and the disassembled cover 3 is closed and locked.

[0060] In this embodiment, the quick-installation method first partially isolates the target tower section and opens the maintenance channel; then, the tray 13 is smoothly moved out to the external processing chamber through the built-in ejection mechanism; offline cleaning, inspection, or replacement is performed here; after completion, it is reset and the maintenance channel is closed, thus realizing the rapid replacement of the ammonia stripping tower tray. The quick-installation method eliminates the need for operators to enter the tower, significantly shortening maintenance time, avoiding high-risk operations, and improving maintenance efficiency and safety.

[0061] Thirdly, the present invention also provides an ammonia stripping tower system, including the aforementioned quick-installation device for the modular ammonia stripping tower trays and a switching valve assembly; as shown above. Figure 9 As shown, the quick-installation device has at least two sets of tower bodies 1 connected in parallel. The switching valve group includes a first switching valve 41 and a second switching valve 42. The upper end interface of all tower bodies 1 is connected to the first switching valve 41, and the lower end interface of all tower bodies 1 is connected to the second switching valve 42. In specific implementation, the liquid phase inlet and gas phase outlet of all tower bodies 1 are collected through the first switching valve 41, and the liquid phase outlet or steam inlet of all tower bodies 1 is collected through the second switching valve 42.

[0062] The ammonia stripping tower system provided in this embodiment connects multiple tower bodies 1 in parallel and sets up a switching valve group. When any tower body 1 or the tray inside the tower body 1 needs maintenance and cleaning, the tower body 1 can be isolated through the switching valve group, while the other tower bodies 1 maintain normal operation, realizing continuous operation without stopping the machine and reducing interference with production. Maintenance work can be carried out without affecting production, and the maintenance and cleaning process is safer, more orderly and controllable.

[0063] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
