Description

Technical Field

[0001] This application relates to the field of heat exchange equipment connection technology, and in particular to a modular large temperature difference absorption heat exchange system and its installation method. Background Technology

[0002] Traditional large temperature difference absorption heat exchanger units include a heat pump main unit, generator, condenser, evaporator, absorber, heat exchanger, detachable plate heat exchanger, and control system. The heat exchange fluid undergoes cascade heat exchange inside the generator, condenser, evaporator, absorber, and heat exchanger, fully absorbing heat from the primary network and storing heat from the low-temperature medium to the high-temperature medium. This reduces the primary network return water temperature to between 15 and 30°C, and makes the supply and return water temperature difference of the primary network reach about 100°C, which greatly improves the heat exchange efficiency.

[0003] Reference Appendix Figure 7 The existing traditional lithium bromide absorption heating system operates on the following principle: The absorption heat exchanger unit mainly utilizes the hygroscopic property of lithium bromide solution and the low boiling point of water under vacuum conditions. It consists of four main components: generator 1, condenser 2, evaporator 3, and absorber 4. It also includes lithium bromide solution and refrigerant water, which circulate within these four components to complete various heat exchange processes. I. Generator 1: The dilute lithium bromide solution is heated and concentrated by high-temperature heat source water in generator 1, producing water vapor and concentrated lithium bromide solution. Simultaneously, the temperature of the heat source water decreases. The water vapor enters condenser 2, and the concentrated lithium bromide solution enters absorber 4. II. Condenser 2: After the water vapor generated by generator 1 enters condenser 2, due to the lower temperature of the external heating water, the water vapor condenses into refrigerant water, releasing heat to the circulating heating water, thus raising the temperature of the heating water. The refrigerant water enters evaporator 3. III. Evaporator 3: After the refrigerant water enters the evaporator 3, its boiling point drops below the temperature of the heat source water due to the reduced pressure. At this time, the refrigerant water evaporates and absorbs heat, and the generated water vapor enters the absorber 4; simultaneously, the heat source water releases heat and its temperature decreases, producing a cooling effect. IV. Absorber 4: In the absorber 4, the concentrated solution absorbs water vapor and is diluted into a dilute solution. This process is exothermic, and the heating return water is heated. The resulting dilute solution re-enters the generator 1, entering the next cycle. However, traditional large temperature difference absorption heat exchanger units are large in size, facing transportation and installation inconveniences in space-constrained environments. In particular, large heat exchangers are difficult to transport to the installation location through narrow passages due to their large size.

[0004] Regarding the aforementioned technologies, large heat exchangers can be broken down into multiple smaller modules and connected by bolts or welding. However, in installation or modification environments where welding is strictly prohibited, traditional large temperature difference absorption heat exchanger units cannot be assembled, thus limiting their widespread adoption. Summary of the Invention

[0005] The purpose of this application is to provide a modular large temperature difference absorption heat exchange system and its installation method.

The high-strength limiting ring is movably positioned on the outer side of the flip-locking buckle. A flange is welded to the end of the connecting tube near the magnetic connector. A positioning ring groove is opened on the outer side of the flange. The positioning block is assembled inside the positioning ring groove.

[0008] Preferably, a connecting wire is installed on one side of the fixing ring, and magnetic step rings are provided on the inner sides of the upper and lower ends of the magnetic connector, with several sets of sealing gaskets provided at the ends of the magnetic step rings.

[0009] Preferably, a torsion spring shaft is installed on the inner side of the lower end of the flip buckle, and a positioning plate is rotatably provided on the outer side of the torsion spring shaft. The positioning plate is welded to the top and bottom of the edge of the magnetic connector. A stop block is installed on the upper end of the flip buckle away from the positioning block. The stop block is located on the side of the high-strength limiting ring away from the fixed ring.

[0010] Preferably, positioning posts are welded and installed on both sides of the high-strength limiting ring, and a limiting plate is installed on the end of the positioning post away from the high-strength limiting ring. Rotating rings are rotatably provided on the outer sides of the two sets of positioning posts.

[0011] Preferably, the inner side of the rotating ring is provided with two sets of arc-shaped sliding grooves, the positioning post is slidably disposed on the inner side of the arc-shaped sliding grooves, and an adjustment handle is installed on the side of the rotating ring away from the high-strength limiting ring.

[0012] Preferably, two sets of transverse movable grooves are provided on the inner side of one end of the adjustment handle, a limit groove is provided on the inner side of the adjustment handle near the movable groove, and an auxiliary locking component is movably provided on the inner side of the adjustment handle.

[0013] Preferably, the auxiliary locking assembly includes a connecting column, with a locking disc installed at the bottom of the connecting column, a movable disc installed at the top of the connecting column, and a strong spring provided at the top of the movable disc. A lifting trapezoidal platform is installed on the side of the movable disc near the limiting groove, and a movable column is installed at the top of the lifting trapezoidal platform, with the movable column slidably disposed inside the limiting groove.

[0014] Preferably, the auxiliary locking assembly includes a movable push rod, which is movably disposed inside one end of the adjusting handle. The top and bottom of the movable push rod are equipped with sliding columns, which are slidably disposed inside the limiting groove. A pressing trapezoidal platform is installed at one end of the movable push rod near the lifting trapezoidal platform, and the pressing trapezoidal platform is in close contact with one side of the lifting trapezoidal platform.

[0015] Preferably, a stepped groove is provided on the inner side of the connecting tube near the magnetic connector, and the magnetic stepped ring is slidably disposed on the inner side of the stepped groove.

[0016] An installation method for a modular large temperature difference absorption heat exchange system:

[0017] S1. Place the magnetic connector to be installed on the flange of the vertical connecting pipe. Use the suspension device to move the upper module to the top of the lower module and assemble them. After the assembly is completed, the staff places the magnetic connector between the horizontal connecting pipes. The same power control turns on the magnetic step ring inside. After powering on, the magnetic attraction drives the magnetic step ring to slide along the inner wall of the magnetic connector through magnetic attraction. The sliding and step grooves combine to compress the sealing gasket.

[0018] S2. Simultaneously grasp the adjustment handles on both sides of one set of magnetic connectors. During the grasping process, contact the movable push rod with your thumb and apply pressure to the movable push rod. After applying pressure, the movable push rod and the sliding column will slide laterally along the limiting groove. During the adjustment process, the movable push rod will drive the extrusion trapezoidal platform to move and extrude pressure to the lifting trapezoidal platform. During the extrusion process, under the guidance of the inclined surface, the lifting trapezoidal platform will cooperate with the movable column to make stable lifting and sliding adjustments along the limiting groove.

[0019] S3. During the lifting process of the lifting trapezoidal platform, the moving plate rises synchronously to compress the strong spring, and the locking plate is pulled up and separated from the fixed ring through the connecting column. After separation, the rotating ring will lose its restriction, and the strong spring between the high-strength limit ring and the fixed ring will push the high-strength limit ring to unfold outward. During the unfolding process, the positioning column will slide stably along the inner side of the arc-shaped slide groove, keeping the high-strength limit ring synchronously unfolding outward to contact the flip buckle.

[0020] S4. Under the action of compression, the flip buckle will flip synchronously along the positioning plate. During the flipping process, the torsion spring shaft will be compressed. At the same time, during the flipping process, the positioning block will be stably combined with the inner side of the positioning ring groove. The high-strength limiting ring will continue to extend outward until it contacts the stop block. After releasing the thumb's movable push rod, the locking plate will be driven outward and combined with the fixing ring for locking under the push of the strong spring. Finally, the sealing of the connection can be changed by controlling the magnetic force as needed.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This invention, through the combination of a magnetic connector, flip-lock buckles, and a high-strength limiting ring, facilitates seamless docking via high-strength magnetic coupling. Furthermore, the quick-lock structure enables rapid installation. Assembly is achieved by inserting the magnetic connector between two sets of flanges. After adjustment, the high-strength limiting ring is pushed outwards by the support spring. During this outward movement, the high-strength limiting ring compresses each set of flip-lock buckles, causing them to flip along the positioning plate. During this flipping process, the positioning blocks of the flip-lock buckles engage with the inner side of the positioning ring groove. This rapid positioning allows for quick assembly of the upper and lower modules. Simultaneously, the magnetic stepped ring inside the magnetic connector further enhances the sealing of the connection through strong adsorption.

[0023] 2. This invention, through the coordinated use of a movable push rod, a movable disc, and a locking disc, facilitates quick locking and unlocking by operators. It allows for pre-installation adjustment of the device before installation, thus shortening installation time. The internal structure is restrained by the adjustment handle, and the movable push rod is pressed with the thumb to provide the pressing driving force. This pressing causes the pressing trapezoidal platform to slide laterally along the inside of the adjustment handle. During this sliding process, the sliding column restricts the movable push rod to ensure stability. The pressing trapezoidal platform and the lifting trapezoidal platform are in contact via an inclined surface. During pressing, guided by the inclined surface, the lifting trapezoidal platform rises along the movable column. This rise, in conjunction with the movable disc compressing the powerful spring, causes the bottom connecting column to rise simultaneously, causing the locking disc to retract and separate from the fixed ring, thus releasing the restriction on the rotating ring. Upon releasing the thumb, the locking disc quickly pops out under the push of the powerful spring, achieving a rapid locking effect and facilitating operator adjustment. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 This application will be described in further detail below.

[0037] Example 1: This invention provides a modular large temperature difference absorption heat exchange system, referring to... Figures 1 to 6The heat exchange system includes a heat exchange module 001 and a connection module 002. The connection module 002 includes several sets of connecting pipes 102. The heat exchange module 001 includes an upper module 100 and a lower module 101. The connecting pipes 102 are fixedly connected to the upper module 100 and the lower module 101. A quick positioning component 003 is provided between the connecting pipes 102.

[0038] The quick positioning assembly 003 includes a magnetic connector 201. Several sets of flip-lock buckles 300 are flipped on the outer sides of the upper and lower ends of the magnetic connector 201. A positioning block 303 is installed on one side of the end of the flip-lock buckle 300. A fixing ring 202 is installed in the middle of the outer side of the magnetic connector 201. Support springs 401 are installed on the top and bottom of the fixing ring 202. A high-strength limiting ring 400 is installed on the side of the support spring 401 away from the fixing ring 202. The high-strength limiting ring 400 is movably arranged on the outer side of the flip-lock buckle 300. A flange 104 is welded to one end of the connecting pipe 102 near the magnetic connector 201. A positioning ring groove 105 is opened on the outer side of the flange 104. The positioning block 303 is assembled and arranged inside the positioning ring groove 105.

[0039] By adopting the above technical solution, the heat exchange module 001 is the main structure of the heat exchange system, which consists of the Type I unit of the upper module 100 and the Type II unit of the lower module 101, as well as the control system. The Type I and Type II units have the same structure, both equipped with a heat pump host, generator, condenser, evaporator, absorber, and heat exchanger, which are filled with lithium bromide solution and refrigerant water. Baffles are installed between the generator and condenser, and between the evaporator and absorber. The plate heat exchanger includes primary and secondary flow channels. The heat exchanger improves efficiency through optimized tube layout. The control system includes a controller and a standby plate heat exchange module 001. The two heat pump hosts are communicatively connected to the controller. The controller is divided into primary network and secondary network heating modules. The standby plate heat exchange module 001 integrates the inlet and outlet valves of each core component and the generator bypass valve.

[0040] It should be noted that the equipment needs to be pressurized during operation to ensure its normal operation. However, it is not necessary to specify the exact atmospheric pressure. The required pressure will vary depending on the environment, the material of the equipment, and different operating conditions. Therefore, the specific amount of pressurization should be based on the actual situation.

[0041] Under normal operating conditions, the unit assembly and commissioning are completed first and connected to the conventional heat exchange station. The heat pump main unit of the two units is started through the controller. The concentrated and dilute lithium bromide solutions are preheated through the heat exchanger, and then flow together with the refrigerant water through the generator and evaporator to reduce the temperature of the heat source water. Subsequently, they flow into the condenser and absorber to raise the temperature of the heating water, completing the cascade heat exchange cycle. After the heat exchange demand is met, the unit is shut down through the controller.

[0042] In the event of a fault, the controller detects the damage to the heat pump unit in real time and triggers the start of the backup plate heat exchange module 001. By switching the valve, only the water-to-water plate heat exchanger inside the unit is used to provide continuous heating, ensuring the stable operation of the heat exchange system.

[0043] The connecting pipe 102 serves as the connection interface between the upper module 100 and the lower module 101. It can be combined with the magnetic connector 201 via the flange 104. The magnetic connector 201 can be connected to an external controller via the connecting line 203. When energized, the internal magnetic stepped ring 204 is energized, generating a magnetic force. This magnetic force allows the magnetic connector 201 to slide along its inner side to the inner side of the stepped groove 103 for adsorption and fixation. The fixing ring 202 provides a restriction for the support spring 401. The support spring 401 can then push the high-strength limiting ring 400 to slide and adjust along the outer side of the magnetic connector 201. The positioning ring groove 105 provides a restriction for the positioning block 303. When the positioning block 303 and the positioning ring groove 105 are combined, the flange 104 is restricted, effectively achieving the locking and restriction effect of the flange 104.

[0044] Reference Figure 3 and Figure 4 As shown, specifically, a connecting wire 203 is installed on one side of the fixing ring 202, and magnetic step rings 204 are provided on the inner sides of the upper and lower ends of the magnetic connector 201. Several sets of sealing gaskets 200 are provided at the ends of the magnetic step rings 204.

[0045] Specifically, a torsion spring shaft 302 is installed on the inner side of the lower end of the flip buckle 300, and a positioning plate 301 is rotatably set on the outer side of the torsion spring shaft 302. The positioning plate 301 is welded to the top and bottom of the edge of the magnetic connector 201. A stop block 304 is installed on the upper end of the flip buckle 300 away from the positioning block 303. The stop block 304 is located on the side of the high-strength limiting ring 400 away from the fixing ring 202.

[0046] Specifically, positioning posts 402 are welded and installed on both sides of the high-strength limiting ring 400, and a limiting plate 403 is installed on the end of the positioning post 402 away from the high-strength limiting ring 400. Rotating rings 404 are rotatably arranged on the outer side of the two sets of positioning posts 402.

[0047] Specifically, the inner side of the rotating ring 404 is provided with two sets of arc-shaped sliding grooves 405, the positioning post 402 is slidably disposed on the inner side of the arc-shaped sliding grooves 405, and an adjustment handle 406 is installed on the side of the rotating ring 404 away from the high-strength limiting ring 400.

[0048] By adopting the above technical solution, the connecting line 203 can be connected to an external controller, which can control the magnetic force of the magnetic step ring 204. The sealing gasket 200 can increase the sealing performance by compression. The positioning plate 301 can be connected to the magnetic connector 201. The positioning plate 301 can restrict the torsion spring shaft 302 and the flip buckle 300. The torsion spring shaft 302 can apply a flipping torque to the flip buckle 300, keeping it in a parallel state with the flange 104 when it is not restricted. The stop block 304 can control high strength. The limiting ring 400 provides restraint, effectively preventing the high-strength limiting ring 400 from falling off. The high-strength limiting ring 400 can push the flip buckle 300 to flip along the torsion spring shaft 302, while also restraining the flip buckle 300 to keep the positioning block 303 always embedded in the inner side of the positioning ring groove 105 for locking. The rotating ring 404 can be adjusted by rotation. The arc-shaped slide groove 405 can restrain the positioning post 402 by rotation. During the rotation, the positioning post 402 can be moved towards the center for adjustment. The adjustment handle 406 provides a grip for the user to easily rotate and adjust.

[0049] like Figure 5 and Figure 6 As shown, specifically, two sets of transverse movable grooves 407 are provided on the inner side of one end of the adjusting handle 406, a limit groove 408 is provided on the inner side of the adjusting handle 406 near the movable groove 407, and an auxiliary locking component 004 is movably provided on the inner side of the adjusting handle 406.

[0050] Specifically, the auxiliary locking component 004 includes a connecting post 508, with a locking disc 500 installed at the bottom of the connecting post 508, a movable disc 506 installed at the top of the connecting post 508, and a strong spring 507 installed at the top of the movable disc 506. A lifting trapezoidal platform 504 is installed on the side of the movable disc 506 near the limiting groove 408, and a movable post 505 is installed at the top of the lifting trapezoidal platform 504. The movable post 505 is slidably disposed inside the limiting groove 408.

[0051] Specifically, the auxiliary locking component 004 includes a movable push rod 501, which is movably disposed inside one end of the adjusting handle 406. Sliding columns 502 are installed at the top and bottom of the movable push rod 501, and the sliding columns 502 are slidably disposed inside the limiting groove 408. A pressing trapezoidal platform 503 is installed at one end of the movable push rod 501 near the lifting trapezoidal platform 504, and the pressing trapezoidal platform 503 is in close contact with one side of the lifting trapezoidal platform 504.

[0052] Specifically, a stepped groove 103 is provided on the inner side of the connecting tube 102 near the magnetic connector 201, and the magnetic stepped ring 204 is slidably disposed on the inner side of the stepped groove 103.

[0053] By adopting the above technical solution, the sliding column 502 can be restricted by the movable groove 407, and the limiting groove 408 can restrict the movable column 505, ensuring that the inner structure can be stably adjusted. The locking plate 500 can be combined with the outer side of the fixed ring 202 through the slot at the bottom of the locking plate 500 to achieve the locking effect. Under the control of the movable plate 506, the locking plate 500 at the bottom can be adjusted by the connecting column 508. The strong spring 507 can push the movable plate 506 outward, which can push the locking plate 500 to combine with the fixed ring 202 to achieve the locking effect. The movable column 505 can stably slide up and down along the inner side of the limiting groove 408 to maintain the stability of the adjustment. The movable push rod 501 can push the squeezing trapezoidal platform 503 to slide and adjust. During the adjustment, the lifting trapezoidal platform 504 can be lifted by the inclined surface to control the lifting of the movable plate 506. The unlocking effect can be achieved by squeezing.

[0054] The implementation principle of this application embodiment is as follows: The magnetic connector 201 to be installed is placed on the flange 104 of the vertical connecting pipe 102. The upper module 100 is moved to the top of the lower module 101 using the suspension device and then assembled. After the assembly is completed, the magnetic connector 201 is placed between the horizontal connecting pipes 102. The magnetic step ring 204 inside is energized by the same power control. After being energized, the magnetic step ring 204 is driven to slide along the inner wall of the magnetic connector 201 by magnetic attraction. The sliding ring combines with the step groove 103 to compress the sealing gasket 200.

[0055] Simultaneously grasp the adjustment handles 406 on both sides of one set of magnetic connectors 201. During the grasping process, the thumb contacts the movable push rod 501 and applies pressure to the movable push rod 501. After applying pressure, the movable push rod 501 and the sliding column 502 can be moved laterally along the limiting groove 408 for adjustment. During the adjustment process, the movable push rod 501 will drive the extrusion trapezoidal platform 503 to move and extrude pressure on the lifting trapezoidal platform 504. During the extrusion process, under the guidance of the inclined surface, the lifting trapezoidal platform 504 will cooperate with the movable column 505 to perform stable lifting and sliding adjustment along the limiting groove 408.

[0056] During the lifting process of the lifting trapezoidal platform 504, the movable plate 506 rises synchronously, compressing the strong spring 507. The locking plate 500 is pulled up and separated from the fixed ring 202 through the connecting column 508. After separation, the rotating ring 404 will lose its restriction. The strong spring 507 between the high-strength limiting ring 400 and the fixed ring 202 will push the high-strength limiting ring 400 to unfold outward. During the unfolding process, the positioning column 402 will slide stably along the inner side of the arc-shaped slide groove 405, keeping the high-strength limiting ring 400 synchronously extending outward to contact the flip buckle 300.

[0057] Under the pressure, the flip buckle 300 will flip synchronously along the positioning plate 301. During the flipping process, the torsion spring shaft 302 will be compressed. At the same time, during the flipping process, the positioning block 303 will be stably combined with the inner side of the positioning ring groove 105. The high-strength limiting ring 400 will continue to extend outward until it contacts the stop block 304. After releasing the thumb's movable push rod 501, the locking disc 500 will be driven outward and combined with the fixing ring 202 for locking under the pushing action of the strong spring 507. Finally, the sealing of the connection can be changed by controlling the magnetic force as needed.

[0058] The embodiments of this specific implementation are applicable not only to heat exchange units with large temperature difference, but also to other heat exchange units with large volume. They facilitate quick locking and unlocking by staff, and make it convenient to adjust the device to the pre-installation state before installation, thereby shortening the installation time and facilitating transportation and assembly.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.

9. The modular large temperature difference absorption heat exchange system according to claim 2, characterized in that: The connecting tube (102) has a stepped groove (103) on the inner side of the end near the magnetic connector (201), and the magnetic stepped ring (204) is slidably disposed on the inner side of the stepped groove (103).

10. The installation method of a modular large temperature difference absorption heat exchange system according to any one of claims 1-9, characterized in that: S1. Place the magnetic connector (201) to be installed on the flange (104) of the vertical connecting pipe (102). Use the suspension device to move the upper module (100) directly above the lower module (101) and assemble it. After the assembly is completed, the staff places the magnetic connector (201) between the horizontal connecting pipes (102). The magnetic step ring (204) inside the same power control is powered on. After being powered on, the magnetic step ring (204) is driven to slide along the inner wall of the magnetic connector (201) by magnetic attraction. The sliding and step groove (103) are combined to squeeze the sealing gasket (200). S2. Simultaneously grasp the adjustment handles (406) on both sides of one set of magnetic connectors (201). During the grasping process, the thumb contacts the movable push rod (501) and applies pressure to the movable push rod (501). After applying pressure, the movable push rod (501) and the sliding column (502) can be driven to slide laterally along the limiting groove (408). During the adjustment process, the movable push rod (501) will drive the extrusion trapezoidal platform (503) to move and extrude the lifting trapezoidal platform (504). During the extrusion process, under the guidance of the inclined surface, the lifting trapezoidal platform (504) will cooperate with the movable column (505) to perform stable lifting and sliding adjustment along the limiting groove (408). S3. During the lifting process of the lifting trapezoidal platform (504), the movable plate (506) is driven to rise synchronously and compress the strong spring (507). The locking plate (500) is pulled up and separated from the fixed ring (202) through the connecting column (508). After separation, the rotating ring (404) will lose its restriction. The strong spring (507) between the high-strength limiting ring (400) and the fixed ring (202) will push the high-strength limiting ring (400) to unfold outward. During the unfolding process, the positioning column (402) will slide stably along the inner side of the arc-shaped slide groove (405) to keep the high-strength limiting ring (400) synchronously extending outward and contacting the flip buckle (300). S4. Under the action of compression, the flip buckle (300) will flip synchronously along the positioning plate (301). During the flipping process, the torsion spring shaft (302) will be compressed. At the same time, during the flipping process of the flip buckle (300), the positioning block (303) will be stably combined with the inner side of the positioning ring groove (105). The high-strength limiting ring (400) will continue to extend outward until it contacts the stop block (304). After releasing the active push rod (501) of the thumb, the locking plate (500) will be driven to extend outward and combine with the fixing ring (202) for locking under the pushing action of the strong spring (507). Finally, the sealing of the connection can be changed by controlling the magnetic force according to the requirements.
