Description

A plate reactor suitable for high pressure differential Technical Field

[0001] This utility model relates to the field of hydrogen production technology, and in particular to a plate reactor suitable for high pressure differential. Background Technology

[0002] Plates (1.5mm-4mm thick) are bulged or molded and then welded together and placed inside the reactor. The plates absorb or release heat through water or other cooling media, and react with external reactants using a catalyst packed within them. The reaction can be exothermic or endothermic. Reactors that absorb or release heat through plates are called plate reactors. However, the plates undergo temperature changes during heat absorption or release, resulting in thermal expansion or contraction. If both ends of the plates are fixed, they may deform or break due to internal stress.

[0003] Existing plate reactors are typically top-suspended. In large plate reactors, such as hydrogenation reactors, a pressure drop of 90 kPa occurs when hydrogen at 180 degrees Celsius passes downwards from the top, resulting in a pressure of approximately 220 tons. The structure of existing top-suspended plate reactors is insufficient to support the weight of the catalyst, the plate itself, the cooling medium within the plate, and the downward pressure from the pressure drop as the material passes through. Especially in some reactions, the pressure drop increases with subsequent catalyst deactivation and coking, further increasing the load on the plate. At relatively limited points of contact, the plate itself cannot withstand the load, and top-suspended plates are prone to swaying or swinging as material passes through. Summary of the Invention

[0004] The purpose of this invention is to provide a plate reactor suitable for high pressure differential, which solves the problems of unstable plate structure and poor load-bearing capacity in the prior art, so that the plate can obtain a more stable foundation while improving the load-bearing capacity of the plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plate reactor suitable for high pressure differential, comprising a shell with a reaction chamber and a heat exchange module located within the reaction chamber, the heat exchange module comprising a plurality of spaced plates, the shell having a material inlet and a material outlet communicating with the reaction chamber, the reaction chamber having a support base, the upper end of the heat exchange module being a free end, and the lower end of the heat exchange module being supported by the support base.

[0006] After adopting the above technical solution, this utility model has the following advantages: The reaction chamber is equipped with a support seat, and the lower end of the heat exchange module is supported by the support seat. This changes the traditional situation where the top is suspended and the bottom is suspended, making it difficult to withstand large downward pressure. The bottom support seat provides stable support, which can better bear the weight of the catalyst, the weight of the plate itself, the weight of the cooling medium, and the pressure drop load generated when the material passes through. It reduces the vibration and shaking caused by fluid impact, improves the safety and reliability of equipment operation, and the bottom support method also helps to distribute the load more evenly, avoiding the local overload situation that may occur in the top suspension method, and improving the load-bearing capacity of the plate. Even if the pressure drop increases due to catalyst deactivation or coking, the bottom support can effectively support the additional load. Secondly, the upper end of the heat exchange module is a free end, avoiding the situation where the two ends of the plate are fixed. When the plate expands or contracts due to temperature changes during heat extraction or release, the free end can provide a certain displacement space, effectively releasing internal stress, reducing the risk of deformation or damage to the plate due to thermal stress, and improving the service life of the plate.

[0007] Furthermore, the support base is also provided with a slot that matches the circumferential shape of the heat exchange module, and the lower end of the heat exchange module is inserted into the slot.

[0008] By adopting the aforementioned technical solution, the slot is adapted to the circumferential shape of the heat exchange module, providing a more precise positioning reference for the heat exchange module during installation. Installers can quickly and accurately place the heat exchange module in the slot. The slot structure can constrain the heat exchange module circumferentially. Compared with simply relying on the support base, it further limits the lateral displacement, swaying, or shaking that the heat exchange module may experience when materials pass through. Even under high pressure differential conditions, when materials exert a large impact on the plates, the fit between the slot and the lower end of the heat exchange module can ensure that the heat exchange module is stably positioned in the set position as much as possible. This enhances the structural stability of the entire heat exchange module in the reactor and allows the pressure generated when materials pass through, the weight of the plates themselves, and other loads to be more evenly distributed on the support base. This method of distributing force avoids local stress concentration and further improves the load-bearing capacity of the heat exchange module. When facing situations such as catalyst deactivation and coking leading to an increase in material pressure drop, it can better withstand the increased load and ensure that the plate reactor can still operate normally under complex conditions.

[0009] Furthermore, the support base includes multiple cross-arranged support legs, which are arranged in an arched, triangular, or Z-shaped manner.

[0010] Using the aforementioned technical solutions, multiple intersecting support legs form a more stable support structure, providing support to the heat exchange module from multiple directions, better distributing the load, and making the heat exchange module more stable within the reactor. The arched structure can evenly distribute the load from above to the support points at both ends. Utilizing the mechanical principles of the arch, it can effectively convert force into its own internal force when subjected to large pressure, thus possessing high load-bearing capacity and effectively supporting the heat exchange module and coping with the pressure from the material. Alternatively, a triangle is a relatively stable geometric structure with strong rigidity and stability. Triangular support legs can provide reliable support for the heat exchange module, maintaining its shape and position even under high pressure differentials and high loads, and are not prone to deformation or collapse. Alternatively, a Z-shaped structure has a certain degree of bending and torsional flexibility, which can adapt to displacement changes in the heat exchange module caused by thermal expansion or contraction to a certain extent.

[0011] Furthermore, the top of the free end of the heat exchange module is suspended from the shell by a retractable expansion structure; or, the free end of the heat exchange module is clamped and fixed to the shell by a circumferential limiting structure.

[0012] By adopting the above technical solution, when the plate expands or contracts due to temperature changes during heat extraction or release, the free end can provide a certain displacement space, effectively releasing internal stress while also supporting the free end of the heat exchange module, thus providing the plate with more stable support. This allows it to better withstand the weight of the catalyst, the weight of the plate itself, the weight of the cooling medium, and the pressure drop load generated when the material passes through, reducing vibration and shaking caused by fluid impact.

[0013] Furthermore, the material inlet is located at the upper end of the housing, the material outlet is located at the lower end of the housing, and there is a gap between the support base and the material outlet so that the support base is suspended in the air.

[0014] The above technical solution allows the support base to be suspended, and correspondingly, the heat exchange module mounted on the support base is also suspended. This minimizes the stress concentration that would occur if the heat exchange module were completely fixed near the material outlet. When the material passes through and other external forces act on the heat exchange module, the suspended end can disperse these forces through slight displacement, reducing local stress. The gap provides a smoother flow channel for the material, reducing the flow resistance at the material outlet and minimizing the formation of dead zones or eddies between the support base and the material outlet, allowing the material to flow out of the reactor more evenly and smoothly.

[0015] Furthermore, the reaction chamber is also equipped with a clamp, which surrounds the heat exchange module circumferentially and holds the heat exchange module tightly.

[0016] The above technical solution tightly surrounds the heat exchange module, so that the heat exchange module is subjected to uniform pressure in the circumferential direction. This helps to avoid excessive local stress on the heat exchange module, reduce the risk of deformation or damage caused by stress concentration, and effectively limit the displacement and shaking of the heat exchange module. When installing the heat exchange module, the clamp can be used as a positioning device to help construction personnel accurately and quickly install the heat exchange module in the predetermined position.

[0017] Furthermore, the reaction chamber is provided with at least two clamps, which are arranged vertically at intervals.

[0018] With the above technical solution, multiple clamps are arranged vertically at intervals, which can fix the heat exchange module at multiple points at different heights. Compared with a single clamp, it can effectively prevent the heat exchange module from moving and shaking in the vertical direction, further enhancing the stability of the heat exchange module and making it less likely to displace or tilt when subjected to the impact force of material flow and equipment vibration.

[0019] Furthermore, two spaced-apart clamps are provided near the support base, and a first reinforcing rib is provided between the two clamps.

[0020] By using the above technical solution, the overall rigidity and bending strength of the area can be significantly increased by setting a first reinforcing rib between the two clamps. This is especially important for the critical part near the support base, which bears a large load and stress. The first reinforcing rib can provide additional support for the clamp, which helps to distribute the weight of the clamp from the heat exchange module and the pressure generated by the material flow, and prevents the clamp from excessive deformation or fatigue damage under long-term stress, so that the clamp can hold the heat exchange module more firmly.

[0021] Furthermore, a second reinforcing rib is provided at the bottom of the clamp away from the support base, and the second reinforcing rib is adapted to the circumferential shape of the heat exchange module.

[0022] With the above technical solution, the clamp is more prone to deformation under these forces because it is far from the support base. The setting of the second reinforcing rib can effectively reduce this deformation, improve the structural stability of the clamp, and ensure its clamping effect on the heat exchange module.

[0023] Furthermore, the heat exchange module also includes a frame for fixing the plates, and the heat exchange module is supported on the support base by the frame.

[0024] Through the above technical solution, the frame provides a robust external support structure for the plates, enhancing the overall rigidity and strength of the heat exchange module, enabling it to better resist the stress brought by external pressure and internal fluid flow, and making it less prone to bending or deformation.

[0042] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0043] As shown in Figures 1 to 10, this utility model provides a plate reactor suitable for high pressure differential, including a shell 10 with a reaction chamber 11 and a heat exchange module 20 located in the reaction chamber 11. The heat exchange module 20 includes a plurality of spaced plates 21. The shell 10 is provided with a material inlet 12 and a material outlet 13 communicating with the reaction chamber 11. The reaction chamber 11 is provided with a support base 30. The upper end of the heat exchange module 20 is a free end 22, and the lower end of the heat exchange module 20 is supported by the support base 30.

[0044] The reaction chamber 11 is equipped with a support base 30, and the lower end of the heat exchange module 20 is supported by the support base 30. This changes the traditional situation where the top is suspended and the bottom is unsupported, making it difficult to withstand large downward pressure. The bottom support base 30 provides stable support, which can better withstand the weight of the catalyst, the weight of the plate 21 itself, the weight of the cooling medium, and the pressure drop load generated when the material passes through. This reduces vibration and shaking caused by fluid impact, improving the safety and reliability of equipment operation. The bottom support also helps to distribute the load more evenly and avoids the local overload that may occur in the top suspension method, improving the load-bearing capacity of the plate 21. Even if the pressure drop increases due to catalyst deactivation or coking, the bottom support can effectively support the additional load. Secondly, the upper end of the heat exchange module 20 is a free end 22, which avoids the situation where the two ends of the plate 21 are fixed. When the plate 21 expands or contracts due to temperature changes during heat extraction or release, the free end 22 can provide a certain displacement space, effectively releasing internal stress, reducing the risk of deformation or damage to the plate 21 due to thermal stress, and improving the service life of the plate 21.

[0045] Preferably, the free end of the heat exchange module 20 has no fixed structure around it, allowing the heat exchange module 20 to expand or contract freely in all directions. The support base 30 is located near the bottom of the reaction chamber 11.

[0046] Plate reactors, for example, are used for hydrogenation reactions. Hydrogen gas at 180 degrees Celsius enters through the material inlet 12 and generates a pressure drop of 90 kPa as it passes downward through the heat exchange module 20. At this point, a pressure of approximately 220 tons is generated. After passing through the heat exchange module 20, the hydrogen gas exits through the material outlet 13. The plates 21 are formed by bulging or molding two thin plates. Considering the water distribution within the plates 21 and the influence of catalyst loading, the plates 21 typically have an aspect ratio of 2-8 times after molding, and a thickness of 1.5 mm-4 mm. The spaced plates 21 form reaction channels 23 for the material to pass through. To ensure that the reaction channels 23 through which the material passes have a more uniform heat extraction space and as similar a pressure drop as possible, the plate reactor is manufactured using modularity to obtain as many identical reaction channels 23 as possible. The heat exchange module 20 also includes a frame 25 and a fixing rod 24 for fixing the plates 21. The plates 21 are set inside the frame 25. The frame 25 provides a robust external support structure for the plates 21, enhancing the overall rigidity and strength of the heat exchange module 20, enabling it to better resist external pressure and stress caused by internal fluid flow. The upper and lower ends of the plates 21 are fixed by the fixing rod 24. The upper and lower ends of the frame 25 are open and connected to the material inlet 12 and the material outlet 13, respectively. The frame 25 is not easy to bend or deform. The heat exchange module 20 is supported on the support base 30 by the frame 25, minimizing the deformation of the heat exchange module 20.

[0047] The plate 21 has a reaction chamber inside, which is connected to the outside via a pipe for the entry and exit of materials to be reacted. The materials to be reacted are input into the reaction chamber through the pipe, and the materials entering through the material inlet 12 transfer heat to the plate 21, raising the reaction temperature inside the chamber and thus enabling the materials to undergo a better reaction. The reacted materials are then transported to the outside through the pipe. The pipe uses a deformable expansion joint, so that when the plate 21 expands and contracts with heat, the pipe can also expand and contract synchronously without changing the connection relationship between them.

[0048] The material inlet 12 is located at the upper end of the shell 10, and the material outlet 12 is located at the lower end of the shell 10. The heat exchange module 20 is placed vertically, with the plates 21 arranged vertically along the axis and the reaction channel 23 arranged vertically along the axis, and connected in a straight line with the material inlet 12 and the material outlet 13. The material in the material inlet 12 can enter the heat exchange module 20 through the free end 22, and the resistance encountered by the material is small. Of course, in other embodiments, the plates 21 can also be arranged at an angle, and the direction of the reaction channel 23 can be connected obliquely with the material inlet 12 and the material outlet 13.

[0049] Furthermore, the support base 30 is also provided with a slot 32 that is adapted to the circumferential shape of the heat exchange module 20, and the lower end of the heat exchange module 20 is inserted into the slot 32. During installation, it provides a more precise positioning reference for the heat exchange module 20, allowing installers to quickly and accurately place the heat exchange module 20 into the slot 32. The slot 32 structure can constrain the heat exchange module 20 circumferentially. Compared with simply relying on the support base 30 for support, it further limits the lateral displacement, swaying, or shaking that the heat exchange module 20 may experience when materials pass through. Even under high pressure differential conditions, when materials exert a large impact on the plate 21, the fit between the slot 32 and the lower end of the heat exchange module 20 can ensure that the heat exchange module 20 is stably positioned in the set position as much as possible. This enhances the structural stability of the entire heat exchange module 20 in the reactor and allows the pressure generated when materials pass through, the weight of the plate 21 itself, and other loads to be more evenly distributed on the support base 30. This method of distributing force avoids local stress concentration and further improves the load-bearing capacity of the heat exchange module 20. When facing situations such as catalyst deactivation and coking leading to an increase in material pressure drop, it can better withstand the increased load and ensure that the plate reactor can still operate normally under complex conditions.

[0050] The support base 30 includes multiple intersecting support legs 33, which form a more stable support structure. This structure provides support to the heat exchange module 20 from multiple directions, better distributing the load and making the heat exchange module 20 more stable within the reactor. In this embodiment, two support legs 33 are provided, each arched in shape. The arched structure evenly distributes the load from above to the support points at both ends. Utilizing the mechanical principle of the arch, it effectively converts the force into its own internal force when subjected to greater pressure, thus possessing high load-bearing capacity and effectively supporting the heat exchange module 20 and coping with the pressure from the material. The two support legs 33 are intersected at a 90-degree angle, providing support while minimizing obstruction to material flow.

[0051] To reduce stress concentration, the support leg 33 is hollowed out with multiple hollowed-out holes 34. When the support leg 33 is under load, the hollowed-out part allows the structure to better adapt to stress changes, reduce stress concentration, and improve the overall structural stability and load-bearing capacity of the support leg 33.

[0052] To position the heat exchange module 20 circumferentially, the reaction chamber 11 is also equipped with a clamp 40. The clamp 40 is arranged around the heat exchange module 20 circumferentially and holds the heat exchange module 20 tightly, so that the heat exchange module 20 is subjected to uniform pressure in the circumferential direction. This helps to avoid excessive local stress on the heat exchange module 20, reduce the risk of deformation or damage caused by stress concentration, and also effectively limit the displacement and shaking of the heat exchange module 20. When installing the heat exchange module 20, the clamp 40 can be used as a positioning device to help the construction personnel accurately and quickly install the heat exchange module 20 in the predetermined position.

[0053] It should be noted that the clamp 40 can be integrally formed with the heat exchange module 20, or it can simply be clamped onto the heat exchange module 20. In this embodiment, the heat exchange module 20 is located in the cylindrical section of the reaction chamber 11. The heat exchange module 20 can be multiple heat exchange units of different sizes. Each heat exchange unit includes a frame 25 and multiple plates 21 disposed within the frame 25. The frame is rectangular prism shaped. The frame 25 of each heat exchange unit is of different sizes to accommodate plates 21 of different sizes for different heat exchange requirements of different materials. Multiple heat exchange units are spliced ​​together radially along the reaction chamber 11. The plates 21 of the multiple heat exchange units are arranged according to the material flow direction, i.e., arranged from the material inlet 12 to the material outlet 13. The inner ring of the clamp 40 is fitted to the surface of the heat exchange module 20, and the outer ring of the clamp 40 is circular and supported on the inner wall of the reaction chamber 11. The heat exchange module 20 is spaced apart from the inner wall of the reaction chamber 11 by the clamp 40.

[0054] Furthermore, the reaction chamber 11 is provided with at least two clamps 40, which are arranged vertically at intervals. The multiple clamps 40 arranged vertically at intervals can fix the heat exchange module 20 at multiple points at different heights. Compared with a single clamp 40, this can effectively prevent the heat exchange module 20 from moving and shaking in the vertical direction, further enhancing the stability of the heat exchange module 20 and making it less prone to displacement or tilting when subjected to the impact force of material flow and equipment vibration.

[0055] It should be noted that the clamp 40 can be provided in appropriate quantities such as two, three, four, or five to form multiple fixing functions.

[0056] Two spaced-apart clamps 40 are provided near the support base 30. Since the clamps 40 are prone to excessive deformation or fatigue damage under long-term stress, a first reinforcing rib 50 is provided between the two clamps 40 in this application. This significantly increases the overall rigidity and bending strength of the area, which is particularly important for the critical part near the support base 30, which bears a large load and stress. The first reinforcing rib 50 provides additional support to the clamps 40, helping to distribute the weight of the heat exchange module 20 and the pressure generated by material flow, thus preventing excessive deformation or fatigue damage under long-term stress and allowing the clamps 40 to more securely hold the heat exchange module 20. A second reinforcing rib 31 is also provided between the two clamps 40, perpendicular to the first reinforcing rib 50. The first reinforcing rib 50, the second reinforcing rib 31, and the two clamps 40 form a support structure, further improving structural strength and reducing deformation. The support structure and the support base 30 together form a groove 32.

[0057] Furthermore, a third reinforcing rib 51 is provided at the bottom of the clamp 40, which is away from the support base 30. The third reinforcing rib 51 is adapted to the circumferential shape of the heat exchange module 20. The setting of the third reinforcing rib 51 can effectively reduce this deformation, improve the structural stability of the clamp 40, and ensure its clamping effect on the heat exchange module 20.

[0058] It should be noted that the first reinforcing rib 50, the second reinforcing rib 31 and the third reinforcing rib 51 are all integral structures and are all attached to the surface of the heat exchange module 20 to adapt to the shape of the heat exchange module 20.

[0059] It should be noted that the first reinforcing rib 50, the second reinforcing rib 31, and the two clamps 40 can be integrally formed, resulting in higher structural strength.

[0060] Due to the presence of a heat source or cold source, the plate 21 will undergo temperature changes, resulting in thermal expansion or contraction. Therefore, in this application, there is a gap 14 between the support 30 and the material outlet 13, so that the support 30 is suspended. Correspondingly, the heat exchange module 20 installed on the support 30 is also suspended, which avoids the situation where the end of the heat exchange module 20 near the material outlet 13 is completely fixed, thus preventing stress concentration. When the material passes through, the pressure and other external forces acting on the heat exchange module 20 can be dispersed by the suspended end through a small displacement, reducing local stress. The existence of the gap 14 provides a smoother flow channel for the material, reduces the flow resistance of the material at the material outlet 13, and avoids the formation of dead zones or eddies between the support 30 and the material outlet 13, so that the material can flow out of the reactor more evenly and smoothly.

[0061] Understandably, in other embodiments, the support legs are arranged in a triangular shape. A triangle is a relatively stable geometric structure with strong rigidity and stability. Triangular support legs can provide reliable support for the heat exchange module and maintain their shape and position even under high pressure differentials and high loads, making them less prone to deformation or collapse.

[0062] Understandably, in other embodiments, the support legs are arranged in a Z-shape. The Z-shaped structure has a certain degree of bending and torsional flexibility, which can adapt to displacement changes caused by thermal expansion or contraction of the heat exchange module to a certain extent.

[0063] Understandably, in other embodiments, an integrally formed limiting rib can also be provided on the support base. The limiting rib and the support base together form a groove. The integrally formed structure has higher strength and is not easily deformed, which can provide more stable and accurate positioning for the supported heat exchange module.

[0064] Understandably, in other embodiments, a slot can be formed by drilling holes in the support base, which can provide more accurate and stable positioning for the supported heat exchange module without the need for additional positioning structures, resulting in a simpler structure.

[0065] Understandably, in other embodiments, the top of the free end of the heat exchange module is suspended from the housing by a retractable expansion structure. When the plates expand or contract due to temperature changes during heat absorption or release, the free end provides a certain displacement space, effectively releasing internal stress while also supporting the free end of the heat exchange module. This provides further stable support for the plates, enabling them to better withstand the weight of the catalyst, the weight of the plates themselves, the weight of the cooling medium, and the pressure drop load generated when materials pass through, reducing vibration and swaying caused by fluid impact. The expansion structure can be an expansion joint, spring, or other structure with a telescoping allowance.

[0066] Understandably, in other embodiments, the free end of the heat exchange module is clamped and fixed to the shell by a circumferential limiting structure. When the plates expand or contract due to temperature changes during heat absorption or release, the free end provides a certain displacement space, effectively releasing internal stress while also supporting the free end of the heat exchange module. This further stabilizes the plates, allowing them to better withstand the weight of the catalyst, the weight of the plates themselves, the weight of the cooling medium, and the pressure drop load generated when materials pass through, reducing vibration and shaking caused by fluid impact. The expansion structure also does not block the reaction channel. The circumferential limiting structure refers to a structure located on the outer periphery of the free end of the heat exchange module that radially limits the free end but does not restrict the axial (vertical) expansion and contraction of the free end, such as a sleeve, vertically arranged grooves, or slide rails.

[0067] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
