Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and in particular to a method and system for improving the heat exchange efficiency of a heat exchanger. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified process temperature to meet process requirements. It is also a key device for improving energy efficiency. The heat exchanger industry is involved in nearly 30 industries, including HVAC, pressure vessels, reclaimed water treatment equipment, chemicals, and petroleum, forming an interconnected industrial chain.

[0003] In the prior art, when a heat exchanger is in use, two tube sheets are installed inside it to connect and fix the pipes. In order to improve the sealing effect, a sealing gasket is installed between the tube sheet and the inner wall of the heat exchanger shell for sealing to prevent liquid leakage. However, the flow rate and pressure generated by the heat exchange liquid inside the heat exchanger when flowing will impact the sealing gasket. Long-term liquid impact will gradually wear the material on the surface of the sealing gasket, causing the sealing gasket to become thinner and the sealing performance to decrease, thereby increasing the risk of heat exchange liquid leakage and affecting the heat exchange effect.

[0004] Therefore, we propose a method and system for improving the heat transfer efficiency of a heat exchanger in order to solve the problems raised in the above background technology. Summary of the Invention

[0016] A method for using a system for improving heat exchange efficiency of a heat exchanger comprises the following steps:

[0017] S1. Unscrew the upper threaded cap and deliver water to the water inlet pipe through an external water supply device. The water first enters the lower annular plate and then enters the sealed capsule through the water inlet hole. After the super absorbent resin material absorbs the water, it expands in the sealed capsule and expands in all directions, causing the sealed capsule to expand and deform, and tightly fit against the inner wall of the shell.

[0018] S2. When the water in the lower annular plate is saturated, water enters the upper annular plate through the connecting pipe, causing the upper sealing bag to expand outward and fit tightly against the inner wall of the shell. At this time, a protective layer is formed on the top and bottom of the sealing gasket;

[0019] S3. As the water level rises, the arc-shaped floating plate moves upward, driving the two limit rods and two racks to move upward at the same time, and driving the gear and the rotating rod to rotate, causing the turntable to rotate. When the staff sees the green colored film at the bottom rotate to the top through the transparent cover, they can turn off the external water supply equipment;

[0020] S4, the cold material liquid inlet pipe transports the cooling liquid into the first tube shell, flows into the wavy copper tube and the spiral copper tube on the right, flows through the second tube shell into the spiral copper tube and the wavy copper tube on the left, and finally enters the first tube shell again and is discharged through the cold material liquid outlet pipe;

[0021] S5. Hot water enters the shell through the hot material liquid inlet pipe, flows along the baffle, exchanges heat with the cooling liquid, and finally the cooled liquid is discharged through the hot material liquid outlet pipe.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When the present invention is used, unscrew the upper threaded cover and transport water to the water inlet pipe through an external water supply device. The water first enters the lower annular plate and then enters the sealing capsule through the water inlet hole. After the super absorbent resin material absorbs water, it expands in the sealing capsule and expands to the surrounding areas, causing the sealing capsule to expand and deform, and fit tightly with the inner wall of the shell. When the water in the annular plate is saturated, the water enters the upper annular plate through the connecting pipe, causing the upper sealing capsule to also expand outward and fit tightly with the inner wall of the shell. At this time, protective layers are formed at the top and bottom of the sealing gasket to protect the sealing gasket and prevent the liquid flow from directly impacting the sealing gasket during subsequent operation of the heat exchanger, thereby protecting the sealing gasket and preventing the sealing gasket from being damaged by liquid impact and affecting the sealing performance. A three-layer sealing layer is formed, which greatly improves the reliability of the seal.

[0024] 2. When the present invention is in use, when the upper superabsorbent resin material becomes saturated with water, water accumulates in the upper annular plate. As the water level rises, it pushes the curved floating plate upward, simultaneously moving the two limit rods and two racks upward, driving the gears and rotating rod to rotate, causing the turntable to rotate. When the staff observes through the transparent cover that the green colored film at the bottom has rotated to the top, it indicates that both sealing bladders have expanded and deformed, firmly fitting against the inner wall of the outer shell. The external water supply can then be turned off. Based on the water supply at this location, water is then injected into the two lowermost annular plates.

[0025] 3. When the present invention is used, the cooling liquid flows in the wavy copper tube and the spiral copper tube, and the hot water flows along the baffle, exchanging heat with the cooling liquid. The wavy copper tube and the spiral copper tube are both made of copper material with high thermal conductivity. The wavy copper tube adopts a wavy setting to increase the contact area between the pipe and the fluid, forming more vortices and enhancing the convective heat transfer effect. The spiral copper tube adopts a spiral structure, which further increases the length and surface area of ​​the pipe, enhances the mixing and disturbance of the fluid, and improves the overall heat transfer effect. The V-shaped guide bar can guide the hot water inside the shell into a specific flow direction, generate more vortices and turbulence, and improve the heat exchange efficiency. The arc-shaped guide bar can make the hot water form a smoother curve flow during the flow process, so that the hot water can be more evenly distributed around the pipe, improving the uniformity of the heat exchange. The irregular inclined guide bar is unevenly distributed and has different inclination directions, which can cause the hot water to produce complex flows in different positions and directions, promote the mixing of hot water, make the temperature of the hot water more uniform, and improve the efficiency of heat exchange.

The top of the outer shell 1 is connected to the first tube shell 4 through a flange. The outer surface of the first tube shell 4 is fixedly connected to the cold material liquid inlet pipe 5. The outer surface of the first tube shell 4 is fixedly connected to the cold material liquid outlet pipe 6 away from the cold material liquid inlet pipe 5. The bottom of the outer shell 1 is connected to the second tube shell 7 through a flange. The bottom of the outer surface of the outer shell 1 is fixedly connected to the hot material liquid outlet pipe 8. The top of the outer surface of the outer shell 1 is fixedly connected to the hot material liquid inlet pipe 9. A liquid separator 10 is fixedly mounted inside the first tube shell 4. The bottom of the liquid separator 10 is fixedly connected to a sealing strip 11. Sealing rings 12 are provided on the top and bottom of the outer shell 1. The outer surfaces of one side of the two sealing rings 12 are in contact with the bottom of the first tube shell 4 and the top of the second tube shell 7 respectively. The bottom of the sealing strip 11 is in contact with the center of the top of one of the connecting plates 201. Both sides of the bottom of the sealing strip 11 are in contact with the outer surface of one of the annular plates 301.

[0040] In this embodiment, when in use, the outer surfaces of the two water inlet pipes 307 and the two connecting pipes 309 are fixedly mounted inside the two connecting plates 201. The top of the uppermost annular plate 301 and the bottom of the lowermost annular plate 301 are both installed with mounting blocks, such as Figure 5 As shown, it is convenient to subsequently install the protective component 3 and the heat exchange component 2 inside the shell 1. The arc floating plate 323 is located between the inner wall of the annular plate 301 and the protective net 305. The sealing gasket 210 is located between the two annular plates 301 and between the two protective guide rings 302. Figure 7Place the heat exchange assembly 2 and the protective assembly 3 into the housing 1 and fix the mounting block into the housing 1 with bolts, thereby fixing the heat exchange assembly 2 inside the housing 1 . At this time, the outer surfaces of the two sealing gaskets 210 are in contact with the inner wall of the housing 1 . First, unscrew the threaded cover 308 at the upper water inlet pipe 307, connect the water pipe of the external water supply equipment to the water inlet pipe 307, and then transport water to the water inlet pipe 307 through the external water supply equipment. The bottom end of the water inlet pipe 307 is connected to the next annular plate 301, so that water first enters the next annular plate 301 and enters the sealing capsule 303 through multiple water inlet holes 306. The sealing capsule 303 is filled with a super absorbent resin material 304. After the super absorbent resin material 304 comes into contact with water, the hydrophilic groups in the resin quickly combine with water molecules, causing the resin particles to swell and form a gel-like substance with a greatly expanded volume. While expanding in the sealing capsule 303, it will expand to the surrounding areas, causing the sealing capsule 303 to expand and deform. A protective guide ring 302 is set at the top and bottom of each sealing capsule 303. Under the limit of the protective guide ring 302, the sealing capsule 303 expands outward, thereby fitting tightly with the inner wall of the shell 1. When the annular plate 301 is saturated with water, the water flows through the connecting pipe 309 into the upper annular plate 301 and into the upper sealing capsule 303 through the upper water inlet 306, causing the upper sealing capsule 303 to expand outward and fit tightly against the inner wall of the housing 1. At this point, the top and bottom of the sealing gasket 210, respectively formed by the protective guide ring 302 and the sealing capsule 303, form a protective layer, protecting the sealing gasket 210 from direct impact from liquid flow during subsequent operation of the heat exchanger. This protects the sealing gasket 210 and prevents damage to the sealing gasket 210 due to liquid impact, which could affect the sealing performance. At this time, the outer surface of the connecting plate 201, in cooperation with the protective component 3 and the sealing gasket 210, forms a three-layer sealing layer, which is composed of the top expanded sealing capsule 303, the middle sealing gasket 210, and the bottom expanded sealing capsule 303. The three-layer sealing structure greatly improves the reliability of the seal. In the event of a leak in one layer of the multi-layer seal, the other layers can still perform a sealing function, forming a redundant design and effectively reducing the risk of leakage. Under the action of the protective component 3, the problem of the flow of heat exchange liquid impacting the sealing gasket when the heat exchanger is in use is solved. Long-term liquid impact will cause the sealing gasket to wear, resulting in thinning of the sealing gasket and reduced sealing performance, thereby increasing the risk of heat exchange liquid leakage and affecting the heat exchange effect. When the super absorbent resin material 304 in the upper sealing bag 303 is saturated with water, the water will gather in the upper annular plate 301 and slowly rise, contacting the bottom of the arc-shaped floating plate 323. As the water level rises, it will push the arc-shaped floating plate 323 to move upward, and push the two limiting rods 312 to move upward, causing the two racks 313 to move upward at the same time, and drive the support rod 319 to slide in the limiting slide groove 321 under the connection of the fixed block 318.The movement of the rack 313 rotates the meshing gear 317, which in turn rotates the rotating rod 316, thereby causing the turntable 314 to rotate. The colored films 315 on the top and bottom of the turntable 314 are different colors, red on the top and green on the bottom. When a worker observes through the transparent cover 322 that the turntable 314 has rotated 180 degrees, causing the top and bottom colored films 315 to swap positions, with the green colored film 315 at the bottom rotating to the top, it indicates that both sealing capsules 303 have expanded and deformed, firmly fitting against the inner wall of the housing 1. The external water supply can then be turned off. Based on the water supply at this location, water can be injected into the two lowermost annular plates 301 to protect the two sealing gaskets 210.

[0041] Example 2: Figure 3-Figure 8As shown, the heat exchange component 2 includes two connecting plates 201, wherein a plurality of wavy copper tubes 202 are fixedly connected to the bottom of one of the connecting plates 201, and the bottom ends of the plurality of wavy copper tubes 202 are fixedly connected to spiral copper tubes 203, and a fixing plate 204 is fixedly installed at the bottom ends of the outer surfaces of the plurality of wavy copper tubes 202, and six baffles 205 are fixedly installed on the outer surfaces of the wavy copper tubes 202 and the spiral copper tubes 203, wherein the tops of two of the baffles 205 are fixedly connected to a plurality of V-shaped guide bars 206, and the tops of the other two baffles 205 are fixedly connected to the plurality of V-shaped guide bars 206. The tops of the two baffles 205 are fixedly connected with a plurality of arc-shaped guide bars 207, and the tops of the two baffles 205 are fixedly connected with a plurality of irregular inclined guide bars 208. The tops of the outer surfaces of the plurality of wavy copper tubes 202 are fixedly installed with anti-collision plates 209. The centers of the outer surfaces of the two connecting plates 201 are fixedly connected with sealing gaskets 210. The outer surfaces of the two connecting plates 201 are located inside the shell 1. The bottom ends of the plurality of spiral copper tubes 203 are fixedly connected to the top of the other connecting plate 201. The outer surfaces of the two sealing gaskets 210 and the six baffles 205 are fixedly connected. The inner walls of the four annular plates 301 are in contact with the inner wall of the shell 1. The inner walls of the four annular plates 301 are fixedly mounted on the top and bottom of the outer surfaces of the two connecting plates 201. The four sealing capsules 303 are located on the top and bottom of the two sealing gaskets 210. The top of the shell 1 is connected to the first tube shell 4 through a flange. The outer surface of the first tube shell 4 is fixedly connected to the cold material liquid inlet pipe 5. The outer surface of the first tube shell 4 is fixedly connected to the cold material liquid outlet pipe 6 away from the cold material liquid inlet pipe 5. The bottom of the shell 1 is connected to the second tube shell 7 through a flange. The bottom of the outer surface of the shell 1 is fixedly connected to the second tube shell 7. A hot material liquid outlet pipe 8 is connected, a hot material liquid inlet pipe 9 is fixedly connected to the top of the outer surface of the shell 1, a liquid separator 10 is fixedly installed inside the first tube shell 4, and a sealing strip 11 is fixedly connected to the bottom of the liquid separator 10. Sealing rings 12 are provided on the top and bottom of the shell 1, and the outer surfaces of one side of the two sealing rings 12 are in contact with the bottom of the first tube shell 4 and the top of the second tube shell 7 respectively. The bottom of the sealing strip 11 is in contact with the center of the top of one of the connecting plates 201, and both sides of the bottom of the sealing strip 11 are in contact with the outer surface of one of the annular plates 301.

[0042] In this embodiment, during use, the heat exchange assembly 2 is installed inside the housing 1 through the protective assembly 3. After the water filling operation is completed, the first tube shell 4 and the second tube shell 7 are respectively installed at the top and bottom of the housing 1 using flanges and bolts. The joints are sealed by sealing rings 12. At this time, the liquid separator 10 is clamped on the upper connecting plate 201, and the sealing strip 11 is tightly fitted with the connecting plate 201 and the annular plate 301, dividing the interior of the first tube shell 4 into two parts. The cooling liquid is transported into the first tube shell 4 through the cold material liquid inlet pipe 5, and enters the wavy copper tube 202 on the right side through the connecting plate 201. Then, it enters the interior of the second tube shell 7 through the connected spiral copper tube 203 and the bottom connecting plate 201. The cooling liquid then enters the spiral copper tube 203 and the wavy copper tube 202 on the left, and then enters the first tube shell 4 again. The liquid that has absorbed heat is discharged through the cold material liquid outlet pipe 6. At the same time, hot water enters the shell 1 through the hot material inlet pipe 9. Under the protection of the anti-collision plate 209, the liquid is prevented from directly impacting the wavy copper tube 202 and affecting the wavy copper tube 202. After the hot water enters the shell 1, it flows along the baffles 205 that are staggered up and down, and finally flows to the bottom of the shell 1. In this process, the hot water and the cooling liquid undergo heat exchange, and finally the cooled liquid is discharged through the hot material outlet pipe 8. The pipeline for the flow of cooling liquid is composed of a wavy copper tube 202 and a spiral copper tube 203, both of which are made of copper material with high thermal conductivity and good thermal conductivity. The wavy copper tube 202 adopts a wavy setting to increase the contact area between the pipeline and the fluid. According to the basic principle of heat transfer, a larger contact area can make heat transfer more sufficient. At the same time, when the fluid flows, the flow direction changes continuously, which will produce strong disturbances and form more eddies, effectively reducing the thermal resistance of the boundary layer and enhancing the convective heat transfer effect. The spiral copper tube 203 adopts a spiral structure, further increasing the length and surface area of ​​the tube, allowing the fluid to have a longer path for heat exchange. Moreover, when the fluid flows in the spiral tube, due to the action of centrifugal force, secondary flow is generated, causing the fluid to form a complex flow pattern on the tube cross section, further enhancing the mixing and disturbance of the fluid and improving the overall heat transfer effect. The baffle 205 is provided with guide bars of different shapes, namely V-shaped guide bars 206, curved guide bars 207, and irregularly inclined guide bars 208. The V-shaped guide bars 206 can guide the hot water inside the shell 1 into a specific flow direction, generating more eddies and turbulence, further destroying the boundary layer and improving the heat exchange efficiency. The curved guide bars 207 can form a smoother curve flow during the flow process, reducing flow resistance while allowing the hot water to be more evenly distributed around the tube, improving the uniformity of heat exchange. The irregularly inclined guide bars 208 are unevenly distributed and have different inclination directions, which can cause the hot water to produce complex flows in different positions and directions, promote the mixing of the hot water, make the hot water temperature more uniform, and improve the efficiency of heat exchange. Under the action of the heat exchange component 2, the heat exchange effect of the heat exchanger is greatly improved.

[0043] The method of use and working principle of the present invention are as follows: the heat exchange component 2 and the protective component 3 are placed in the housing 1 and fixed with bolts. At this time, the outer surfaces of the two sealing gaskets 210 are in contact with the inner wall of the housing 1. First, unscrew the threaded cap 308 at the upper water inlet pipe 307, connect the water pipe of the external water supply device to the water inlet pipe 307, and then transport water to the water inlet pipe 307 through the external water supply device. The water first enters the next annular plate 301 and enters the sealing capsule 303 through the water inlet hole 306. After the super absorbent resin material 304 comes into contact with water, it expands in the sealing capsule 303 and expands in all directions, causing the sealing capsule 303 to expand and deform. Under the limit of the protective guide ring 302, the sealing capsule 303 expands outward, thereby tightly contacting the inner wall of the housing 1. When the water in the annular plate 301 is saturated, the water will enter the upper annular plate 301 through the connecting pipe 309 and enter the upper sealing capsule 303 through the upper water inlet 306, causing the upper sealing capsule 303 to expand outward and fit tightly against the inner wall of the shell 1. At this time, the top and bottom of the sealing gasket 210 are respectively formed into a protective layer by the protective guide ring 302 and the sealing capsule 303, which protects the sealing gasket 210 and prevents the liquid flow from directly impacting the sealing gasket 210 during subsequent operation of the heat exchanger, thereby protecting the sealing gasket 210. At this time, the outer surface of the connecting plate 201 forms a three-layer sealing layer with the cooperation of the protective component 3 and the sealing gasket 210, respectively consisting of the top expanded sealing capsule 303, the middle sealing gasket 210, and the bottom expanded sealing capsule 303. The three-layer sealing structure greatly improves the reliability of the seal. When the superabsorbent resin material 304 in the upper sealing bladder 303 becomes saturated with water, water accumulates in the upper annular plate 301 and slowly rises, contacting the bottom of the curved floating plate 323. As the water level rises, it pushes the curved floating plate 323 upward, pushing the two limiting rods 312 upward, causing the two racks 313 to move upward simultaneously. Connected to the fixed block 318, the support rods 319 slide within the limiting chute 321. The movement of the racks 313 rotates the meshing gear 317, which in turn rotates the rotating rod 316, thereby rotating the turntable 314. When the operator observes through the transparent cover 322 that the green colored film 315 at the bottom has rotated to the top, it indicates that both sealing bladders 303 have expanded and deformed, firmly fitting against the inner wall of the housing 1. The external water supply can then be turned off. Based on the water supply at this location, water can be added to the two lowermost annular plates 301 to protect the two sealing gaskets 210. Then, the first tube shell 4 and the second tube shell 7 are respectively installed at the top and bottom of the housing 1 by flanges and bolts, and the joints are sealed by sealing rings 12.The cooling liquid is delivered to the first tube shell 4 via the cold material inlet pipe 5 and enters the wavy copper tube 202 on the right side through the connecting plate 201. It then enters the interior of the second tube shell 7 through the connected spiral copper tube 203 and the connecting plate 201 at the bottom. The cooling liquid then enters the spiral copper tube 203 and wavy copper tube 202 on the left side, and then enters the first tube shell 4 again. The liquid, which has absorbed heat, is discharged through the cold material outlet pipe 6. At the same time, hot water enters the outer shell 1 through the hot material inlet pipe 9, flows along the baffles 205 arranged in an alternating pattern, and finally flows to the bottom of the outer shell 1. During this process, the hot water and the cooling liquid exchange heat, and the cooled liquid is finally discharged through the hot material outlet pipe 8. The pipe for the cooling liquid flow is composed of the wavy copper tube 202 and the spiral copper tube 203, both made of copper with high thermal conductivity. The wavy copper tube 202 is arranged in a wavy shape, which increases the contact area between the pipe and the fluid, ensuring more efficient heat transfer. The spiral copper tube 203 adopts a spiral structure, which further increases the length and surface area of ​​the pipe, allowing the fluid to have a longer path for heat exchange. Moreover, when the fluid flows in the spiral pipe, due to the action of centrifugal force, secondary flow will be generated, causing the fluid to form a complex flow pattern on the pipe cross section, further enhancing the mixing and disturbance of the fluid and improving the overall heat transfer effect. Different shapes of guide bars are respectively provided on the baffle 205. The V-shaped guide bar 206 can guide the hot water inside the shell 1 into a specific flow direction, generating more eddies and turbulence, further destroying the boundary layer and improving the heat exchange efficiency. The arc-shaped guide bar 207 can make the hot water form a smoother curve flow during the flow process, reducing the flow resistance while allowing the hot water to be more evenly distributed around the pipe, improving the uniformity of heat exchange. The irregular inclined guide bar 208 is unevenly distributed and has different inclination directions, which can cause the hot water to produce complex flows in different positions and directions, promote the mixing of the hot water, make the hot water temperature more uniform, and improve the efficiency of heat exchange.
