Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and specifically 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 realizes heat transfer between materials among two or more fluids at different temperatures. It enables heat to be transferred from a fluid at a higher temperature to a fluid at a lower temperature, so that the temperature of the fluid reaches the specified index of the process, to meet the needs of process conditions. At the same time, it is also one of the main devices for improving energy utilization efficiency. The heat exchanger industry involves nearly thirty industries such as heating ventilation, pressure vessels, medium water treatment equipment, chemical engineering, and petroleum, forming an industrial chain with each other.

[0003] In the prior art, when a heat exchanger is in use, two tube sheets are installed inside it to connect and fix the pipelines. To improve the sealing effect, a 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 velocity and pressure generated by the flowing heat exchange liquid inside the heat exchanger will impact the gasket. Long-term liquid impact will gradually wear the material on the surface of the gasket, resulting in the thinning of the gasket and the decline of the sealing performance, 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 exchange efficiency of a heat exchanger to solve the problems raised in the above background art. Summary of the Invention

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

[0017] S1. Unscrew the upper threaded cover. Water is conveyed into 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 holes. After the superabsorbent resin material absorbs water, it expands and expands in all directions while in the sealing capsule, causing the sealing capsule to expand and deform and closely fit with the inner wall of the housing.

[0018] S2. When the water in the lower annular plate is saturated, the water enters the upper annular plate through the connecting pipe, causing the upper sealing capsule to expand outward and closely fit against the inner wall of the outer shell. At this time, protective layers are formed at both the top and bottom of the sealing gasket.

[0019] S3. As the water level rises, it pushes the arc-shaped floating plate upward, driving the two limit rods and the two racks to move upward simultaneously, and driving the gear and the rotating rod to rotate, causing the turntable to rotate. When the staff sees through the transparent cover that the green colored film at the bottom rotates to the top, the external water supply device can be closed.

[0020] S4. The cold material inlet pipe transports the cooling liquid into the first pipe shell, where it enters the right corrugated copper pipe and the spiral copper pipe to flow, enters the left spiral copper pipe and the corrugated copper pipe through the second pipe shell to flow, and finally enters the first pipe shell again and is discharged through the cold material outlet pipe.

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

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. When the present invention is in use, unscrew the upper threaded cover, and use an external water supply device to transport water into the water inlet pipe. The water first enters the lower annular plate and enters the sealing capsule through the water inlet holes. After the superabsorbent resin material absorbs water, it expands and expands in all directions while in the sealing capsule, causing the sealing capsule to expand and deform and closely fit against the inner wall of the outer shell. When the water in this 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 closely fit against the inner wall of the outer shell. At this time, protective layers are formed at both the top and bottom of the sealing gasket to protect the sealing gasket, preventing the liquid flow from directly impacting the sealing gasket during the subsequent operation of the heat exchanger, thereby protecting the sealing gasket from being damaged by the liquid impact and affecting the sealing performance. And a three-layer sealing layer is formed, greatly improving the reliability of the sealing.

[0024] 2. When the present invention is in use, when the superabsorbent resin material in the upper part absorbs water and becomes saturated, the water will accumulate in the upper annular plate. As the water level rises, it pushes the arc-shaped floating plate upward, and also pushes the two limit rods and the two racks to move upward simultaneously, driving the rotation of the gear and the rotating rod, causing the turntable to rotate. When the staff sees through the transparent cover that the green colored film at the bottom rotates to the top, it indicates that both sealing capsules have expanded and deformed and are tightly attached to the inner wall of the outer shell. Then the external water supply device can be closed. According to the water supply reference at this place, the two lower annular plates are filled with water.

[0025] 3. When the present invention is in use, the cooling liquid flows through the corrugated copper tube and the spiral copper tube, and the hot water flows along the baffle plate, undergoing heat exchange with the cooling liquid. Both the corrugated copper tube and the spiral copper tube are made of copper material with a high thermal conductivity. The corrugated copper tube is arranged in a corrugated shape, increasing the contact area between the pipe and the fluid, forming more eddies, and enhancing the convective heat transfer effect. The spiral copper tube adopts a spiral structure, further increasing the length and surface area of the pipe, enhancing the mixing and disturbance of the fluid, and improving the overall heat transfer effect. The V-shaped guide bar can guide the hot water inside the housing into a specific flow direction, generating more eddies and turbulence, and improving the heat exchange efficiency. The arc-shaped guide bar can make the hot water form a smoother curve flow during the flow process, enabling the hot water to be more evenly distributed around the pipe, and improving the uniformity of heat exchange. The irregular inclined guide bars are unevenly distributed and have different inclined directions, which can make the hot water generate complex flows at different positions and directions, promoting the mixing of the hot water, making the temperature of the hot water more uniform, and improving the heat exchange efficiency.

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, during use, the outer surfaces of the two water inlet pipes 307 and the two communication pipes 309 are respectively fixedly installed inside the two connecting plates 201. Installation blocks are installed at both the top of the uppermost annular plate 301 and the bottom of the lowermost annular plate 301, as Figure 5 shown, which facilitates the subsequent installation of the protection component 3 and the heat exchange component 2 inside the outer shell 1. The arc-shaped floating plate 323 is located between the inner wall of the annular plate 301 and the protection net 305. The sealing gasket 210 is located between the two annular plates 301 and between the two protective guide rings 302, as Figure 7As shown. Place the heat exchange component 2 and the protection component 3 into the housing 1, and fix the mounting block in the housing 1 through bolts, thereby fixing the heat exchange component 2 inside the housing 1. At this time, the outer surfaces of both sealing washers 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 use the external water supply device to transport water into the water inlet pipe 307. The bottom end of the water inlet pipe 307 is communicated with the next annular plate 301, so that the water first enters the next annular plate 301 and enters the sealing bladder 303 through a plurality of water inlet holes 306. The sealing bladder 303 is filled with a superabsorbent resin material 304. After the superabsorbent resin material 304 contacts water, the hydrophilic groups in the resin quickly combine with water molecules, causing the resin particles to swell, forming a gel-like substance with a large volume expansion. While expanding in the sealing bladder 303, it will expand in all directions, causing the sealing bladder 303 to expand and deform. Protective guide rings 302 are provided at the top and bottom of each sealing bladder 303. Under the limitation of the protective guide rings 302, the sealing bladder 303 expands outward, so as to be in close contact with the inner wall of the housing 1. When the water in this annular plate 301 is saturated, the water will enter the upper annular plate 301 through the connecting pipe 309 and enter the upper sealing bladder 303 through the upper water inlet holes 306, causing the upper sealing bladder 303 to also expand outward and be in close contact with the inner wall of the housing 1. At this time, a protective layer is formed at the top and bottom of the sealing washer 210 respectively by the protective guide ring 302 and the sealing bladder 303 to protect the sealing washer 210, avoiding direct impact on the sealing washer 210 caused by the liquid flow during the subsequent operation of the heat exchanger, thereby playing a protective role for the sealing washer 210 and preventing the sealing washer 210 from being damaged by liquid impact and affecting the sealing performance. At this time, the outer surface of the connecting plate 201 forms three sealing layers under the cooperation of the protection component 3 and the sealing washer 210, which are respectively composed of the sealing bladder 303 expanded at the top, the middle sealing washer 210, and the sealing bladder 303 expanded at the bottom. The three-layer sealing structure greatly improves the reliability of the sealing. Multiple layers of sealing can still play a sealing role when one layer leaks, forming a redundant design and effectively reducing the risk of leakage. Under the action of the protection component 3, the problem that when the heat exchanger is in use, the flow of the heat exchange liquid will impact the gasket, and the long-term liquid impact will cause the gasket to wear, resulting in the thinning of the gasket and the decline of the sealing performance, thereby increasing the risk of leakage of the heat exchange liquid and affecting the heat exchange effect is solved. When the superabsorbent resin material 304 in the upper sealing bladder 303 is saturated with water, the water will accumulate 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 upward and push the two limit rods 312 upward, causing the two racks 313 to move upward simultaneously. Under the connection of the fixed block 318, it drives the support rod 319 to slide in the limit sliding groove 321.The movement of the rack 313 drives the rotation of the gear 317 meshed and connected thereto, and drives the rotation of the rotating rod 316, thereby causing the turntable 314 to rotate. The colors of the color films 315 at the top and bottom of the turntable 314 are different, the top is red and the bottom is green. When the staff sees through the transparent cover 322 that the turntable 314 rotates 118 degrees, causing the position exchange of the color films 315 at the top and bottom, that is, when the green color film 315 at the bottom rotates to the top, it indicates that both of the two sealing capsules 303 have expanded and deformed and are tightly attached to the inner wall of the outer shell 1, and then the external water supply equipment can be closed. According to the water supply reference at this place, the two annular plates 301 at the bottom are injected with water to protect the two sealing washers 210.

A sealing strip 11 is fixedly connected to the bottom of the liquid distribution plate 10. Sealing rings 12 are provided at the top and bottom of the housing 1. The outer surfaces of one sides of the two sealing rings 12 are respectively in contact with the bottom of the first pipe shell 4 and the top of the second pipe shell 7. The bottom of the sealing strip 11 is in contact with the center of the top of one of the connecting plates 201. The two 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 component 2 is installed inside the housing 1 through the protection component 3. After the water injection 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 through flanges and bolts, and the connection is sealed by the sealing ring 12. At this time, the liquid distribution plate 10 is stuck on the upper connecting plate 201, and the sealing strip 11 is closely attached to 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 inlet pipe 5, enters the wavy copper tube 202 on the right through the connecting plate 201, then enters the second tube shell 7 through the connected spiral copper tube 203 and the bottom connecting plate 201. Immediately afterwards, the cooling liquid enters the spiral copper tube 203 and the wavy copper tube 202 on the left, and then enters the first tube shell 4 again, and the liquid after absorbing heat is discharged through the cold material outlet pipe 6. At the same time, hot water enters the housing 1 through the hot material inlet pipe 9. Under the protection of the anti-impact 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 housing 1, it flows along the baffle plates 205 distributed alternately up and down, and finally flows to the bottom of the housing 1. During this process, heat exchange occurs between the hot water and the cooling liquid, and finally the cooled liquid is discharged through the hot material outlet pipe 8. The pipes through which the cooling liquid flows are composed of the wavy copper tube 202 and the spiral copper tube 203, both of which are made of copper material with a high thermal conductivity coefficient and have good heat conduction effects. The wavy copper tube 202 is arranged in a wavy shape, increasing the contact area between the pipe 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, generating strong disturbances and forming more eddies, effectively thinning the boundary layer thermal resistance and strengthening the convective heat transfer effect. The spiral copper tube 203 adopts a spiral structure, further increasing 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, a secondary flow will be generated, causing the fluid to form a complex flow pattern on the cross-section of the pipe, further enhancing the mixing and disturbance of the fluid and improving the overall heat transfer effect. Different forms of flow guiding strips are respectively arranged on the baffle plates 205, namely the V-shaped flow guiding strip 206, the arc-shaped flow guiding strip 207 and the irregular inclined flow guiding strip 208. The V-shaped flow guiding strip 206 can guide the hot water inside the housing 1 into a specific flow direction, generating more eddies and turbulences, further destroying the boundary layer and improving the heat exchange efficiency. The arc-shaped flow guiding strip 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 flow guiding strip 208 shows uneven distribution and different inclined directions, which can make the hot water generate complex flows at different positions and directions, promoting the mixing of the hot water, making the temperature of the hot water more uniform, and improving the heat exchange efficiency. Under the action of the heat exchange component 2, the heat exchange effect of the heat exchanger is greatly improved.

[0043] The usage method and working principle of the present invention are as follows: Place the heat exchange component 2 and the protection component 3 into the outer shell 1 and fix them with bolts. At this time, the outer surfaces of both sealing washers 210 are in contact with the inner wall of the outer shell 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 use the external water supply device to transport water into the water inlet pipe 307. The water first enters the lower annular plate 301 and enters the sealing capsule 303 through the water inlet holes 306. After the superabsorbent resin material 304 contacts the water, it expands in the sealing capsule 303 and expands outwards at the same time, causing the sealing capsule 303 to expand and deform. Under the limitation of the protection guide ring 302, the sealing capsule 303 expands outwards and thus fits tightly with the inner wall of the outer shell 1. When the water in this 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 holes 306, causing the upper sealing capsule 303 to also expand outwards and fit tightly with the inner wall of the outer shell 1. At this time, a protection layer is formed by the protection guide ring 302 and the sealing capsule 303 at the top and bottom of the sealing washer 210 respectively to protect the sealing washer 210 and prevent the liquid flow from directly impacting the sealing washer 210 during the subsequent operation of the heat exchanger, thereby protecting the sealing washer 210. At this time, the outer surface of the connecting plate 201 forms three sealing layers under the cooperation of the protection component 3 and the sealing washer 210, which are composed of the expanded sealing capsule 303 at the top, the middle sealing washer 210, and the expanded sealing capsule 303 at the bottom respectively. The three-layer sealing structure greatly improves the reliability of the seal. When the superabsorbent resin material 304 in the upper sealing capsule 303 is saturated with water, the water will accumulate 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 upwards and push the two limit rods 312 upwards, causing the two racks 313 to move upwards simultaneously. Under the connection of the fixed block 318, it drives the support rod 319 to slide in the limit sliding groove 321. The movement of the rack 313 will drive the gear 317 meshed with it to rotate and drive the rotating rod 316 to rotate, thereby causing the turntable 314 to rotate. When the staff sees through the transparent cover 322 that the green color film 315 at the bottom rotates to the top, it indicates that both sealing capsules 303 have expanded and deformed and are tightly attached to the inner wall of the outer shell 1, and then the external water supply device can be closed. According to the water supply reference at this place, the two lower annular plates 301 can be filled with water to protect the two sealing washers 210. Then, the first pipe shell 4 and the second pipe shell 7 are respectively installed at the top and bottom of the outer shell 1 through flanges and bolts, and the connection is sealed by the sealing ring 12.Cooling liquid is transported into the first shell 4 through the cold feed liquid pipe 5, enters the corrugated copper pipe 202 on the right through the connecting plate 201, then enters the interior of the second shell 7 through the connected spiral copper pipe 203 and the connecting plate 201 at the bottom. Immediately afterwards, the cooling liquid enters the spiral copper pipe 203 and the corrugated copper pipe 202 on the left, and then enters the first shell 4 again, and the liquid after absorbing heat is discharged through the cold feed liquid discharge pipe 6. At the same time, hot water enters the outer shell 1 through the hot feed liquid pipe 9, flows along the baffles 205 distributed in a staggered manner up and down, and finally flows to the bottom of the outer shell 1. During this process, heat exchange occurs between the hot water and the cooling liquid, and finally the cooled liquid is discharged through the hot feed liquid discharge pipe 8. The pipes through which the cooling liquid flows are composed of the corrugated copper pipe 202 and the spiral copper pipe 203, both of which are made of copper material with high thermal conductivity. The corrugated copper pipe 202 is arranged in a corrugated shape, increasing the contact area between the pipe and the fluid, and making heat transfer more sufficient. The spiral copper pipe 203 adopts a spiral structure, further increasing 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, a secondary flow will be generated, causing the fluid to form a complex flow pattern on the cross-section of the pipe, further enhancing the mixing and disturbance of the fluid, and improving the overall heat transfer effect. Different forms of flow guiding strips are respectively arranged on the baffle 205. The V-shaped flow guiding strip 206 can guide the hot water inside the outer shell 1 into a specific flow direction, generating more eddies and turbulences, further destroying the boundary layer, and improving the heat exchange efficiency. The arc-shaped flow guiding strip 207 can make the hot water form a smoother curve flow during the flowing 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 flow guiding strip 208 is unevenly distributed and has different inclined directions, which can make the hot water generate complex flows at different positions and directions, promoting the mixing of the hot water, making the temperature of the hot water more uniform, and improving the efficiency of heat exchange.
