Abstract
Description
Technical Field
[0001] This invention belongs to the field of heat exchanger technology and relates to an assembly device for a high-efficiency heat exchanger. Background Technology
[0002] Shell-and-tube heat exchangers are the most widely used type of heat exchanger in chemical and alcohol production. They mainly consist of a shell, tube sheet, heat exchange tubes, end caps, and baffles (also called flow deflectors). During heat exchange, one fluid enters through the connecting pipe at the end cap, flows inside the heat exchange tubes, and exits through the outlet pipe at the other end of the end cap; this is called the tube side. The other fluid enters through a connecting pipe in the shell and exits through another connecting pipe on the shell; this is called the shell side.
[0003] Currently, in the production process, two tube sheets and all baffles are first fixed. Then, workers insert the heat exchange tubes through all the tube sheets and baffles from one side of the tube sheet until all the heat exchange tubes have been inserted. Finally, the heat exchange tubes are sealed to the tube sheet by welding or expansion. To ensure the baffles effectively guide the fluid, the diameter of the heat exchange tubes is usually not too different from the orifice diameter on the baffles. However, when the heat exchange tubes are long, they are prone to elastic deformation under their own weight. This results in low insertion efficiency or requires multiple people working together, such as one person pushing the tube from behind while another person inserts the end of the heat exchange tube through the baffles and tube sheet from the front, leading to poor operational efficiency.

The upper notch baffle plate includes a first perforated plate and a second perforated plate attached to the first perforated plate. Both sides of the first perforated plate are vertically provided with a first slide rail with an L-shaped cross-section. Both ends of the second perforated plate and the side facing away from the first perforated plate are movably attached to the inner side of the first slide rail.

Several flow-disrupting arms perpendicular to the flow-disrupting rod are provided on the side wall of the flow-disrupting rod. The free end of the flow-disrupting arm is provided with a plate-shaped flow-disrupting blade. When the fluid passes through the baffle, the flow-disrupting blade drives the flow-disrupting rod to rotate through the flow-disrupting arm, and lifts up the fluid located on both sides of the upper and lower notch baffle.
[0037] Compared with existing technologies, this invention provides an assembly device for a high-efficiency heat exchanger. During the insertion of heat exchange tubes, a drive mechanism moves the second and third frames, reducing the distance between them and the first frame. Preferably, the first frame, all the third frames, and the second frame are in contact with each other (preferably, linear bearings are provided on both the second and third frames to reduce friction with the guide rods). Then, the tube sheet is inserted into the first support groove, and the baffles are inserted into the second support groove (placement can also be done before moving the second and third frames). The heat exchange tubes can then be inserted one by one through the tube sheet and all the baffles. Because the distance between the tube sheet and the baffles is very small, the insertion of heat exchange tubes is relatively convenient. Furthermore, the small distance between adjacent baffles effectively prevents deformation of the baffles; almost no deformation is visible to the naked eye during the actual insertion process, making the insertion process simpler and more convenient.
[0038] The process involves passing the heat exchange tube end through the tube sheet, allowing it to pass over the second frame. A tube-guiding mechanism then pulls the heat exchange tube away from the first frame, while the drive mechanism moves in the same direction as the heat exchange tube until it reaches the desired position. At this point, all spacing cables remain taut. Since the spacing cable length is fixed, the distances between the first frame and the nearest third frame, between adjacent third frames, and between the second frame and the nearest third frame are all equal and fixed. Therefore, driving the second frame is sufficient to move all the third frames to their designated positions. Finally, the tube-guiding mechanism separates from the heat exchange tube, completing the passage operation with good results. Attached Figure Description

Detailed Implementation
[0060] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed account of the assembly equipment for a high-efficiency heat exchanger proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention. The same or similar reference numerals in the drawings represent the same or similar parts.
[0061] An assembly device for a high-efficiency heat exchanger, such as Figures 1 to 20 As shown, it includes:
[0062] A supporting base plate 1 is provided, and a first supporting frame 2, a second supporting frame 3 and a first frame 4 are fixedly provided on the top of the supporting base plate 1. A plurality of guide rods 5 are horizontally arranged between the first supporting frame 2 and the second supporting frame 3, and the guide rods 5 pass through the first frame 4.
[0063] The second frame 6 and several third frames 7, all of the guide rods 5 pass through the second frame 6 and the third frames 7, and the outer wall of the guide rods 5 is attached to the second frame 6 and the third frames 7. The top of the first frame 4 and the second frame 6 are provided with an arc-shaped first support arc 8, and the middle of the first support arc 8 is provided with an arc-shaped first support groove 9. Each first support groove 9 is used to support a tube sheet. The top of the third frame 7 is provided with an arc-shaped second support arc 10, and the middle of the second support arc 10 is provided with an arc-shaped second support groove 11. Each second support groove 11 is used to support a baffle plate. The first frame 4 and the second frame 6 are located between the first support frame 2 and the second support frame 3, and all of the third frames 7 are located between the first frame 4 and the second frame 6.
[0064] Spacing cable 12, the two third frames 7 located at the edge are respectively between the first frame 4 and the second frame 6, and between two adjacent third frames 7;
[0065] A drive mechanism is used to drive the second frame 6 to move closer to or away from the first frame 4;
[0066] The second frame 6 is located between the first frame 4 and the tube guiding mechanism, which is used to pull the heat exchange tubes that pass over the second frame 6.
[0067] The supporting base plate 1 is also provided with several supporting mechanisms. The first supporting frame 2 is located between the supporting mechanism and the first frame 4. The supporting mechanism includes two vertical auxiliary columns 13. Several auxiliary rods 14 are horizontally rotatably arranged between the two auxiliary columns 13. Each auxiliary rod 14 is used to support several heat exchange tubes.
[0068] The tube-guiding mechanism includes:
[0069] The pipe guide frame 15, all the guide rods 5 pass through the pipe guide frame 15, and the outer wall of the guide rod 5 is attached to the pipe guide frame 15. The pipe guide frame 15 is located between the second frame 6 and the second support frame 3.
[0070] The pipe guide plate 16 is vertically arranged on the top of the pipe guide frame 15. A plurality of pipe guide holes 17 are opened through the pipe guide plate 16. The guide rod 5 passes through the pipe guide plate 16, and the outer wall of the guide rod 5 is movably attached to the pipe guide plate 16.
[0071] Each of the aforementioned tube fittings includes a tube ring 18 and two tube sections 19 located on the side of the tube ring 18 near the second frame 6. A through-hole 20 with a rectangular longitudinal section is provided through the middle of the tube ring 18. The two tube sections 19 are located on both sides of the through-hole 20. The tube sections 19 are made of elastic or flexible material. The outer side of the tube section 19 is arc-shaped. The minimum distance between the outer wall of the tube section 19 and the straight line containing the axis of the corresponding tube ring 18 decreases as the distance between the tube section 19 and the tube plate 16 increases (the figure is for illustration only and does not represent the actual structure).
[0072] A traction plate 21 is provided with several traction columns 22 horizontally arranged on its side. Each traction column 22 is movably attached to the inner wall of a through-hole 20. Each free end of the traction column 22 is provided with a traction part 23. The two opposite sides of the traction part 23 are movably attached to two lead-in pipe parts 19. The thickness of the traction part 23 increases as the distance between it and the traction column 22 increases. The traction part 23 can allow the free ends of the two traction parts 23 to be inserted into the corresponding heat exchange tubes, or allow the outer side of the traction part 23 to be attached to the inner wall of the corresponding heat exchange tube.
[0073] A traction motor 24, wherein a first winding column is horizontally arranged on the output shaft of the traction motor 24;
[0074] The first traction cable 25 has one end wound around the first winding post and the other end fixedly connected to the side of the traction plate 21 away from the guide tube plate 16.
[0075] A tensioning screw 26 is horizontally rotatably mounted in the middle of the guide plate 16. The tensioning screw 26 passes through the traction plate 21 and is threadedly connected to the traction plate 21.
[0076] It also includes a uniform member 27. Several uniform cables 28 are arranged around the periphery of the traction plate 21 on the side opposite to the guide tube plate 16. The free ends of all the uniform cables 28 and the end of the first traction cable 25 are connected to the uniform member 27. When the first traction cable 25 pulls the traction plate 21, it acts evenly on the edge of the traction plate 21 through the uniform member 27 and the uniform cables 28. Thus, even though the traction plate 21 has a large area, it can be stably pulled. Furthermore, the first traction cable 25 between the first steering wheel 31 and the uniform member 27 is horizontal, further improving the traction stability of the traction plate 21.
[0077] Two support seats 29 are provided on the support base plate 1. A support shaft is horizontally rotatably arranged between the two support seats 29. The first winding column is fixedly connected to the support shaft in a coaxial shape. The output shaft of the traction motor 24 is connected to one end of the support shaft. A first steering rod 30 is horizontally arranged on the second support frame 3. A first steering wheel 31 is rotatably arranged on the first steering rod 30. The middle part of the first traction cable 25 is movably wound around the first steering wheel 31. When traction heat exchange tube, the first traction cable 25 located between the first steering wheel 31 and the uniform member 27 is in a horizontal state.
[0078] The top of the supporting base plate 1 is provided with a clearance groove 32, and the driving mechanism includes:
[0079] The second steering rod 33 has a second steering wheel 34 rotatably mounted on it, and the second steering wheel 34 is located between the first frame 4 and the first support frame 2.
[0080] The second winding column is coaxially fixed on the support shaft;
[0081] The second traction cable 35 has one end fixedly connected to the second frame 6, and the other end wound around the outer wall of the second winding column. Its middle portion moves around the second steering wheel 34. The winding direction of the second traction cable 35 is opposite to that of the first traction cable 25. When the length of the first traction cable 25 on the first winding column increases, the length of the second traction cable 35 on the second winding column decreases. The second support frame 3, the first frame 4, and all the third frames 7 have openings for the second traction cable 35 to pass through. When the first traction cable 25 pulls all the heat exchange tubes, the second traction cable 35 is in a non-taut state and / or the second traction cable... The second traction cable 35 has a set elasticity, meaning that the second traction cable 35 has a certain amount of movement, such as a certain degree of looseness, or the second traction cable 35 is made of a material with a certain degree of elasticity, such as a conventional rope or belt, rather than a steel cable or chain. In this way, when the traction column 22 and the traction part 23 loosen the tension on the heat exchange tube, the traction motor 24 needs to rotate to release a certain length of the first traction cable 25 before the tension screw 26 can be rotated to bring the traction plate 21 and the lead tube plate 16 closer to each other. However, the second frame 6 needs to remain in place at this time. Therefore, if the second traction cable 35 is taut at this time and has no elastic deformation or only a very small elastic deformation, the traction plate 21 cannot get close to the lead tube plate 16.
[0082] Synchronizing element 36, which is vertically hinged to the side of the guide tube frame 15, and the free end of the synchronizing element 36 is provided with a synchronizing part 37 perpendicular to the synchronizing element 36;
[0083] Synchronization column 38 is horizontally disposed on the side of the second frame 6. When the synchronization part 37 is fastened to the synchronization column 38, the second frame 6 abuts against the guide pipe frame 15.
[0084] Both sides of the guide tube frame 15 have the synchronizing element 36. The free end of the synchronizing part 37 is threadedly connected with an anti-detachment part 39 perpendicular to the synchronizing part 37. The anti-detachment part 39 abuts against the bottom of the synchronizing column 38. The outer wall of the first steering wheel 31 has a first anti-detachment groove for the first traction cable 25 to be inserted. The outer wall of the first steering rod 30 has several U-shaped first anti-detachment parts 40. The distance between the middle of the first anti-detachment part 40 and the outer wall of the first steering wheel 31 is smaller than the diameter of the first traction cable 25 (thus, the first traction cable 25 can be stably applied to the first steering wheel 31 by the first anti-detachment groove and the first anti-detachment part 40). The outer wall of the second steering wheel 34 has a second anti-detachment groove for the second traction cable 35 to be inserted. The outer wall of the second steering rod 33 is provided with several U-shaped second anti-detachment parts 41. The distance between the middle part of the second anti-detachment part 41 and the outer wall of the second steering wheel 34 is smaller than the diameter of the second traction cable 35 (thus, the second anti-detachment groove and the second anti-detachment part 41 can make the second traction cable 35 stably act on the second steering wheel 34). The support shaft is provided with a first limiting plate 42, a second limiting plate 43 and a third limiting plate 44 in sequence. The first traction cable 25 is located between the first limiting plate 42 and the second limiting plate 43, and the second traction cable 35 is located between the second limiting plate 43 and the third limiting plate 44. This can effectively prevent the first traction cable 25 and the second traction cable 35 from getting tangled or interacting with each other, ensuring that the assembly can proceed normally.
[0085] The second support groove 11 has a receiving groove 45 on the side of the top end.
[0086] The present invention also discloses a baffle plate for an assembly device of a high-efficiency heat exchanger as described above, comprising an upper notch baffle plate 46 and a lower notch baffle plate 47 (the upper notch baffle plate 46 and the lower notch baffle plate 47 are arranged alternately in sequence). The upper notch baffle plate 46 includes a first perforated plate 46a (which is subsequently welded to the heat exchanger shell or fixedly connected in other ways) and a second perforated plate 46b attached to the first perforated plate 46a. Both sides of the first perforated plate 46a are vertically provided with a first slide rail 48 with an L-shaped cross section. Both ends of the second perforated plate 46b and the side away from the first perforated plate 46a are movably attached to the inner side of the first slide rail 48. A plurality of first large openings 49 are opened through the first perforated plate 46a, and a first small opening 50 is opened at the bottom of each first large opening 49. A plurality of second large openings 51 are opened through the second perforated plate 46b, and a second small opening 52 is opened at the top of each second large opening 51.
[0087] The lower notch baffle 47 includes a third orifice plate 47a and a fourth orifice plate 47b attached to the third orifice plate 47a (which is subsequently welded to or otherwise fixedly connected to the heat exchanger shell). The third orifice plate 47a has vertically arranged L-shaped second slide rails 53 on both sides. The two ends and the side of the fourth orifice plate 47b facing away from the third orifice plate 47a are movably attached to the inner side of the second slide rails 53. Several large third openings 54 are formed through the third orifice plate 47a, and each large third opening 54 has a small third opening 55 at its bottom. Several large fourth openings 55 are formed through the fourth orifice plate 47b. Each of the four large openings 56 has a fourth small opening 57 at its top. The diameters of the first large opening 49, the second large opening 51, the third large opening 54, and the fourth large opening 56 are all larger than the diameter of the heat exchange tube. The diameters of the first small opening 50, the second small opening 52, the third small opening 55, and the fourth small opening 57 are all equal to the diameter of the heat exchange tube. When the heat exchange tube is inserted, the first large opening 49, the second large opening 51, the third large opening 54, and the fourth large opening 56 through which the same heat exchange tube passes are coaxial.
[0088] The bottom and sides of the first slide rail 48 and the second slide rail 53 abut against the inner wall of the corresponding receiving groove 45;
[0089] A first fixed seat is provided on the side of the first perforated plate 46a, and a first movable seat 58 is provided on the side of the second perforated plate 46b. A first adjusting rod is vertically provided on the first fixed seat and is rotatably connected to the first fixed seat. The first adjusting rod is threadedly connected to the first movable seat 58.

A second adjusting rod 61 is vertically provided on the second fixed seat 59 and is rotatably connected to the second fixed seat 59. The second adjusting rod 61 is threadedly connected to the second movable seat 60.
[0091] The first orifice plate 46a, the second orifice plate 46b, the third orifice plate 47a, and the fourth orifice plate 47b are all provided with a turbulence structure (which does not act on the heat exchange tube or the inner wall of the shell). The turbulence structure includes two horizontal turbulence frames 62, and a turbulence rod 63 is horizontally rotatably arranged between the two turbulence frames 62. Several turbulence arms 64 perpendicular to the turbulence rod 63 are provided on the side wall of the turbulence rod 63. The free end of the turbulence arm 64 is provided with a plate-shaped turbulence blade 65. When the fluid passes through the baffle, the turbulence blade 65 drives the turbulence rod 63 to rotate through the turbulence arm 64, and lifts the fluid located on both sides of the upper notch baffle 46 and the lower notch baffle 47.
[0092] This invention provides an assembly device for a high-efficiency heat exchanger. During the insertion of heat exchanger tubes, a drive mechanism moves the second frame 6 and the third frame 7, reducing the distance between them and the first frame 4. Preferably, the first frame 4, all the third frames 7, and the second frame 6 are in contact with each other (preferably, both the second frame 6 and the third frame 7 have linear bearings to reduce friction with the guide rod 5). Then, the tube sheet is inserted into the first support groove 9, and the baffles are inserted into the second support groove 11 (placement can also be done before moving the second frame 6 and the third frame 7). Afterward, the heat exchanger tubes can be inserted one by one through the tube sheet and all the baffles. Because the distance between the tube sheet and the baffles is very small, the insertion of the heat exchanger tubes is relatively convenient. Furthermore, the small distance between adjacent baffles effectively prevents deformation of the baffles; almost no deformation is visible to the naked eye during the actual insertion process, making the insertion simpler and more convenient.
[0093] The process involves passing the end of the heat exchange tube through the tube sheet, allowing it to pass over the second frame 6. Then, a tube-guiding mechanism pulls the heat exchange tube away from the first frame 4, while the drive mechanism moves in the same direction as the heat exchange tube until it reaches the desired position. At this point, all the spacing cables 12 remain taut. Since the length of the spacing cables 12 is fixed, the distances between the first frame 4 and the nearest third frame 7, between adjacent third frames 7, and between the second frame 6 and the nearest third frame 7 are all equal and fixed. Therefore, driving the second frame 6 is sufficient to move all the third frames 7 to their designated positions. Finally, the tube-guiding mechanism separates from the heat exchange tube, completing the passage operation with good results.
[0094] In the actual production process, in the initial state, the synchronizing component 36, the synchronizing part 37, and the anti-detachment part 39 are fastened to the synchronizing column 38, and the second frame 6 and the guide tube frame 15 are in contact. At the same time, the traction plate 21 and the guide tube plate 16 are in contact or close to each other, so that the traction part 23 is located outside the guide tube part 19 or a small number of traction parts 23 are located between the guide tube parts 19, so that the outer wall of the guide tube part 19 forms a shape similar to a frustum, and the largest end of the frustum is located at the traction ring.
[0095] Then the traction motor 24 drives the support shaft to rotate, which in turn drives the first winding column and the second winding column to rotate. At this time, the first winding column releases the first traction cable 25, and the second winding column winds the second traction cable 35. Therefore, the second frame 6 moves towards the first frame 4, and the traction plate 21 can also move normally.
[0096] When the second frame 6 moves to its maximum distance, the second frame 6, the third frame 7, and the first frame 4 sequentially abut (or sequentially abut via linear bearings). Then, the worker manually or with tools places the tube sheet into the first support groove 9 and the baffle plate into the second support groove 11. The bottom and outer sides of the first slide rail 48 and the second slide rail 53 abut against the inner wall of the receiving groove 45, thus ensuring the angle and position of the upper notch baffle plate 46 and the lower notch baffle plate 47. Simultaneously, there are indicator holes on both sides of the tube sheet, into which indicator rods are inserted. Finally, the two indicator rods abut against the top ends of the first frame 4 or the second frame 6, thus fixing the position of the tube sheet. Both the tube sheet and the baffle plate maintain their stable position through gravity.
[0097] Next, the worker takes the heat exchanger tubes that need to be threaded and places them on the auxiliary rod 14. The number of support structures varies depending on the length of the heat exchanger tube. Then, the heat exchanger tube is moved along the length of the guide rod 5, passing through the tube sheet, several baffles, and another tube sheet in sequence, until the end of the heat exchanger tube touches the traction plate 21. At this point, two lead-in tubes 19 are inserted into the end of the heat exchanger tube. Then, the same operation is performed until all the heat exchanger tubes are moved to touch the traction plate 21. During the movement of the traction heat exchanger tubes, the outer ends of all the heat exchanger tubes are supported by the corresponding auxiliary rods 14, which effectively prevents deformation of the heat exchanger tubes.
[0098] At this point, the first movable seat 58 abuts against the first fixed seat, the second movable seat 60 abuts against the second fixed seat 59, and the first large opening 49 communicates with the second large opening 51, and the third large opening 54 communicates with the fourth large opening 56. Preferably, the projections of the first large opening 49 and the second large opening 51 along the length of the guide rod 5 form a complete circle, and the projections of the third large opening 54 and the fourth large opening 56 along the length of the guide rod 5 form a complete circle. The diameters of these two circles are equal and both are larger than the diameter of the heat exchange tube. Since the diameter of the circle through which the heat exchange tube needs to pass is larger than the heat exchange tube, the operation of passing the heat exchange tube is simpler and more convenient. At the same time, since the distances between the third frames 7, between the third frame 7 and the first frame 4, and between the third frame 7 and the second frame 6 are very small, and the outside of the heat exchange tube is also supported by an auxiliary rod 14 (depending on the actual situation, the auxiliary rod 14 above the heat exchange tube can also limit the heat exchange tube), the operation of passing the heat exchange tube is simple, labor-saving, and efficient.
[0099] After all the heat exchange tubes are threaded, manually turn the handwheel at the outer end of the tensioning screw 26 to separate the traction plate 21 from the lead tube plate 16. During this operation, the first traction cable 25 will become slightly loose, but the second traction cable 35 will not be affected. As the distance between the traction plate 21 and the lead tube plate 16 increases, the traction part 23 gradually enters between the two lead tube parts 19 and squeezes the lead tube parts 19 outward, so that the outer side of the lead tube part 19 abuts against the inner wall of the corresponding heat exchange tube; then continue to turn the handwheel, causing the lead tube part 19 to undergo elastic deformation and have a sufficiently large compressive force with the heat exchange tube.
[0100] Then, the traction motor 24 drives the support shaft, the first winding column, and the second winding column, causing the first traction cable 25 to wind and the second traction cable 35 to be released. Thus, even if the second frame 6 and the tube rack 15 are stationary at this time, the tube rack 15 can still move normally. During this movement, all heat exchange tubes are pulled by the corresponding tube components, and the heat exchange tubes can abut against the tube plate 16, thereby driving the tube plate 16 to move (since the traction part 23 cannot pass through the through-hole 20, the traction plate 21 can drive the tube plate 16 to move even without heat exchange tubes). Afterwards, the tube plate 16 drives the second frame 6 through the synchronizing member 36, and then the second frame 6 drives all the third frames 7 to move through several spacing cables 12. During this process, relative movement also occurs between the heat exchange tubes and the baffles.
[0101] When the above-mentioned traction heat exchange tubes and the second frame 6 are moving, the second traction cable 35 is in a loose state; then when the second frame 6 moves to the maximum distance, all the spacing cables 12 are in a taut state; then the second winding column winds a portion of the second traction cable 35, and the first winding column releases a portion of the first traction cable 25. Since the second traction cable 35 had a certain degree of slack before, the movement of the second winding column at this time will not cause the position of the second frame 6 to change, but it will free up a certain space so that the traction plate 21 can approach the lead tube plate 16.
[0102] At this point, the worker manually turns the handwheel, using the tension screw 26 to bring the traction plate 21 and the lead-in tube plate 16 closer together until the traction plate 21 is in contact with the lead-in tube plate 16. At this point, the traction part 23 is located outside the two lead-in tube parts 19, or only a small portion is located between the two lead-in tube parts 19, and the outer wall of the lead-in tube part 19 is separated from the inner wall of the heat exchange tube. Then, after unscrewing the anti-detachment part 39, the worker rotates the synchronizing part 36 upwards, and can then manually move the lead-in tube bracket 15, causing all the lead-in tube parts 19 to separate from the heat exchange tube.
[0103] The worker then rotates the first adjusting rod, causing both the first orifice plate 46a and the second orifice plate 46b to move towards the heat exchange tube until the first small opening 50 and the second small opening 52 are respectively attached to the outer wall of the heat exchange tube. Similarly, the second adjusting rod 61 is rotated until the third small opening 55 and the fourth small opening 57 are respectively attached to the outer wall of the heat exchange tube, thus completing the fixed connection between the baffle and the heat exchange tube. Since the heat exchange tube can be in no contact with the upper notch baffle 46 and the lower notch baffle 47 after passing through them (even if there is contact, there is only a small amount of resistance), when the third frame 7 is moved by the second frame 6 using the spacing cable 12, there is little or no friction between the upper notch baffle 46 and the lower notch baffle 47 and the heat exchange tube, which reduces noise generation and wear.
[0104] In actual operation, to prevent deformation of the heat exchange tubes, anti-deformation rods can be horizontally inserted below one or more rows of heat exchange tubes. After the anti-deformation rods support the heat exchange tubes, the first and second adjusting rods 61 are rotated. Simultaneously, to further improve the relative positional stability between the baffles and the heat exchange tubes, spot welding can be performed at several points on the edges of the first orifice plate 46a and the second orifice plate 46b, and spot welding can be performed at several points on the edges of the third orifice plate 47a and the fourth orifice plate 47b. Then, the heat exchange tubes are welded or expanded and sealed to the tube sheets at both ends, thus forming a single integral structure of the tube sheets, heat exchange tubes, and baffles.
[0105] In conventional heat exchange tubes, the diameter is typically slightly smaller than the baffle plate to allow them to pass through. This not only makes tube installation more difficult but also, because a gap still exists between the heat exchange tube and the baffle plate, it can still cause vibration and noise in the heat exchange tube, as well as wear and even leakage during subsequent use. However, in this application, the baffle plate and heat exchange tube are ultimately fixed and tightly connected, thus effectively ensuring the service life and heat exchange quality of the heat exchanger.
[0106] Conventional baffles, during use, create dead zones for flow and heat transfer in fluid transition zones, near inlet and outlet, and in eddy current stagnation zones. This not only reduces heat transfer efficiency but also often results in insufficient scouring, leading to scale buildup and a decrease in the overall heat transfer coefficient. In this embodiment, turbulence structures are placed at locations that do not affect the heat exchange tubes. When fluid passes through, it acts on the turbulence vanes 65 located far from the transition zone (or dead zone), causing the turbulence rod 63 and the turbulence vanes 65 within the dead zone to rotate. This agitates the liquid within the dead zone, effectively preventing scale buildup and improving the heat transfer coefficient and service life of the equipment.
[0107] In another embodiment, the traction plate 21 and the guide tube plate 16 are attracted by a magnet, so that when passing through, the guide tube plate 16 can pull the traction plate 21 to move by the magnet; then when the traction plate 21 is subjected to tension, the traction plate 21 can be driven to move under the action of instantaneous tension, and the traction plate 21 and the guide tube plate 16 are separated, so that the traction part 23 can normally expand the guide tube part 19.
[0108] In another embodiment, when the heat exchanger tube is inserted, the first large opening 49 is directly opposite the second small opening 52, the first small opening 50 is directly opposite the second large opening 51, the third large opening 54 is directly opposite the fourth small opening 57, and the third small opening 55 is directly opposite the fourth large opening 56. The diameters of the first large opening 49, the second large opening 51, the third large opening 54, and the fourth large opening 56 are all larger than the diameter of the heat exchanger tube, and the diameters of the first small opening 50, the second small opening 52, the third small opening 55, and the fourth small opening 57 are all equal to the diameter of the heat exchanger tube. Although the first large opening 49, the second large opening 51, the third large opening 54, and the fourth large opening 56 are not coaxial during tube insertion (the opening used for tube insertion is the largest at this time), the bottom of the heat exchange tube can move against the bottom of the inner wall of the first small opening 50 and the third small opening 55. Since the diameter of the second large opening 51 and the third large opening 54 is larger than the diameter of the heat exchange tube, the opening formed by the first orifice plate 46a and the second orifice plate 46b for the heat exchange tube to pass through is still larger than the diameter of the heat exchange tube, which also facilitates the heat exchange tube to pass through the upper notch baffle plate 46 and the lower notch baffle plate 47. Furthermore, after the heat exchange tubes are pulled to the designated position, when the first and second adjusting rods 61 are rotated, the positions of the first orifice plate 46a and the third orifice plate 47a remain unchanged. Instead, only the second orifice plate 46b and the fourth orifice plate 47b are lowered until the first orifice plate 46a and the second orifice plate 46b clamp the heat exchange tubes through the first small opening 50, the second small opening 52, the third small opening 55, and the fourth small opening 57. During this process, the upper notch baffle plate 46 and the lower notch baffle plate 47 are continuously supported by the third frame 7.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
