Description

Technical Field

[0001] This utility model relates to the field of heat exchanger equipment, and in particular to a regenerative heat exchanger with recoverable waste heat. Background Technology

[0002] Regenerative heat exchangers, as highly efficient waste heat recovery devices, possess unique advantages. They achieve effective heat transfer and recovery by alternately storing and releasing heat between hot and cold fluids through a heat storage medium. Compared to traditional heat exchangers, regenerative heat exchangers offer higher heat exchange efficiency, larger heat capacity, and better adaptability. They can handle waste heat resources with significant temperature and flow fluctuations and can operate at higher temperatures, making them suitable for waste heat recovery in various industrial sectors.

[0003] The heat storage medium in a heat exchanger continuously absorbs waste heat, but because there is no cold fluid to remove the heat, the temperature of the heat storage medium continues to rise. This sustained high temperature causes the heat exchanger's outer shell to expand, potentially leading to deformation, damage, or even failure of the heat storage medium. This affects the normal operation and lifespan of the heat exchanger, reducing energy efficiency. In industrial production environments, waste heat fluids often contain impurities such as dust and particles. Over long-term operation, these impurities gradually accumulate in the pores and channels of the heat storage medium. If these impurities cannot be flushed away in time, they increase the flow resistance and reduce the flow rate within the heat storage medium. This reduces the heat exchange area and contact time between the hot and cold fluids and the heat storage medium, ultimately leading to a decrease in heat exchange efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a waste heat recovery regenerative heat exchanger, which can effectively solve the problems of deformation, damage, or even failure, affecting the normal operation and service life of the heat exchanger, reducing energy utilization efficiency, and reducing the heat exchange area and contact time between the hot and cold fluids and the heat storage body, ultimately leading to a decrease in heat exchange efficiency.

[0008] Furthermore, support frames are fixedly connected to the bottom left and right sides of the cylinder, and anti-slip pads are fixedly connected to the bottom of the two support frames.

[0009] Furthermore, a cleaning fluid dispensing pipe is connected through the top right side of the cylinder, and support plates are fixedly connected to the front and rear sides of the bottom wall of the upper partition. A bottom box is fixedly connected to the bottom of the multiple support plates, and a hydraulic rod is provided at the bottom of each support plate. The multiple hydraulic rods are located inside the bottom box, and a water tank plate is fixedly connected to the front and rear sides of the upper side wall of the upper partition.

[0010] Furthermore, a fixing block is fixedly connected to the outer side of the telescopic end of each hydraulic rod, a first connecting rod is fixedly connected to the inner side wall of each of the multiple support plates, a second connecting rod is rotatably connected to the outer side of the other side of each of the first connecting rods, a first hinge frame is fixedly connected to the upper side wall of each fixing block, a support rod is rotatably connected inside each of the first hinge frames, and a second hinge frame is rotatably connected to the outer side of the other side of each of the multiple support rods.

[0011] Furthermore, the rear sidewalls of the plurality of second hinge frames are fixedly connected to the front sidewall of each second connecting rod, the bottom of the plurality of second connecting rods are connected through a connecting post, the rear end of the plurality of connecting posts are fixedly connected to a fixing ring, a hose is fixedly connected inside each fixing ring, the bottom ends of the plurality of hoses are connected to a nozzle, and the top ends of the plurality of hoses are connected through the interior of the upper partition and connected to the interior of the water tank plate.

By incorporating a support plate, hydraulic rod, first hinge frame, support rod, hose, nozzle, and water tank plate, the problem of reduced heat exchange area and contact time between hot and cold fluids and the heat storage medium, ultimately leading to decreased heat exchange efficiency, can be solved. The rising of the fixed block, via the first connecting rod and the rotatably connected second connecting rod, drives the entire cleaning structure. A connecting column runs through the bottom of the support rod; as the angle of the support rod changes, it moves the fixed ring and the connected hose and nozzle. During this movement, the nozzle gradually extends from its initial retracted state to its working position, allowing it to be aimed at the area to be cleaned. This effectively reduces heat loss during transfer, further improving the heat exchanger's heat exchange effect and enhancing the stability and reliability of the entire equipment.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1 - Figure 4 As shown: A waste heat recovery regenerative heat exchanger includes a cylinder 1. An upper partition 2 is fixedly connected to the top of the inside of the cylinder 1. Two upper guide plates 4 are fixedly connected to the bottom of the upper partition 2. A lower partition 3 is fixedly connected to the bottom of the inside of the cylinder 1. The upper partition 2 and the lower partition 3 are used to divide the inside of the cylinder 1 into areas. The top area divided by the upper partition 2 is the cleaning fluid storage layer, and the bottom area divided by the lower partition 3 is the impurity collection area.

[0019] Three lower guide plates 5 are fixedly connected to the top of each lower partition 3. The two upper guide plates 4 and the three lower guide plates 5 are arranged in a cross configuration. The two upper guide plates 4 and the lower guide plates 5 guide the hot fluid entering the cylinder 1 through the hot fluid inlet pipe 11, allowing the hot fluid to contact the cold fluid inside the tube 8, thereby reducing the heat of the hot fluid and transferring it to the cold fluid. Each lower partition 3 has a removal groove 13 inside. The removal groove 13 allows residual impurities in the hot fluid to flow into the bottom area and into the collection box 15 for collection.

[0020] A baffle 6 is fixedly connected to the left side of the interior of the cylinder 1. A partition plate 7 is fixedly connected to the left side wall of the baffle 6. A tube 8 is connected through the top of the baffle 6. The middle outer side of the tube 8 is connected through the interior of the upper guide plate 4 and the lower guide plate 5. The bottom end of the tube 8 is connected through the bottom of the baffle 6. A cold fluid inlet pipe 9 is connected through the top left side of the cylinder 1. The bottom end of the cold fluid inlet pipe 9 is located on the upper side wall of the partition plate 7. A cold fluid outlet pipe 10 is located at the bottom of the partition plate 7. The left end of the cold fluid outlet pipe 10 is connected through the left side wall of the cylinder 1. The fluid flows through the baffle 6 fixedly connected to the left side of the interior of the cylinder 1 and the partition plate 7 on the left side wall of the baffle 6. The partition plate 7 divides the interior left side of the cylinder 1 into regions. The top region of the partition plate 7 is used to initially collect the cold fluid that is transported into the interior of the cylinder 1 through the cold fluid inlet pipe 9. The collected cold fluid will be driven by the baffle plate 6 to enter the interior of the tube 8 through the orifice to come into contact with the hot fluid and heat the cold fluid. The bottom of the partition plate 7 is used as the area for the cold fluid to be discharged and collected. The heated cold fluid enters the bottom region of the partition plate 7 and is discharged again through the cold fluid outlet pipe 10 on the left side of the cylinder 1 and transported to the next equipment for use.

[0021] like Figure 1 - Figure 5 As shown, a sieve plate 12 is fixedly connected to the right side of the inside of the cylinder 1. A hot fluid inlet pipe 11 is connected through the right side wall of the cylinder 1. The bottom wall of the sieve plate 12 is fixedly connected to the top of the right side wall of the lower partition 3. The hot fluid is transported into the inside of the cylinder 1 through the hot fluid inlet pipe 11 on the right side of the cylinder 1. The hot fluid that just enters the inside of the cylinder 1 will come into contact with the sieve plate 12. The sieve plate 12 can initially filter out larger particles of impurities in the hot fluid, preventing them from entering the subsequent heat exchange area and causing blockage. The hot fluid that has been initially filtered flows to the left.

[0022] A hot fluid outlet pipe 14 is connected through the left side of the bottom wall of the cylinder 1. When the hot fluid comes into contact with the cold fluid inside the tube 8 and is cooled, the hot fluid is discharged from the inside of the cylinder 1 through the hot fluid outlet pipe 14. A debris collection box 15 is fixedly connected to the bottom of the cylinder 1. A guide plate 16 is fixedly connected inside the debris collection box 15. A debris discharge pipe 17 is connected through the front side wall of the debris collection box 15. A baffle plate 18 is installed inside the debris discharge pipe 17. The debris collection box 15 and multiple debris removal tanks 13 are correspondingly arranged. During the flow of the hot fluid... Some denser impurities will settle downwards under the influence of gravity and fall into the impurity removal trough 13 inside the lower partition 3. Since the impurity removal trough 13 is correspondingly set with the impurity collection box 15, the impurities will fall into the impurity collection box 15 through the impurity removal trough 13, and the impurities inside the impurity collection box 15 will be guided by the guide plate 16 inside the impurity collection box 15, so that these impurities will flow to the discharge pipe 17 on the front side. When cleaning is required, the impurities are discharged by removing the baffle plate 18 inside the discharge pipe 17.

[0023] like Figure 1 - Figure 8 As shown, support frames 19 are fixedly connected to the bottom left and right sides of the cylinder 1. Anti-slip pads 20 are fixedly connected to the bottom of the two support frames 19. The support frames 19 support the bottom of the entire device, and the anti-slip pads 20 at the bottom of the support frames 19 contact the external ground to prevent the device from sliding on the ground and thus failing to be fixed on the ground.

[0024] A cleaning fluid inlet pipe 21 is connected through the top right side of the cylinder 1. Cleaning fluid is introduced into the cylinder 1 through the inlet pipe 21 and enters the top area of ​​the upper partition 2. When the cleaning fluid reaches a certain capacity, it enters the interior of the water tank plate 35. Support plates 22 are fixedly connected to the front and rear sides of the bottom wall of the upper partition 2. A base box 23 is fixedly connected to the bottom of each support plate 22. A hydraulic rod 24 is installed at the bottom of each support plate 22, and the hydraulic rods 24 are located inside the base box 23. Water tank plates 35 are fixedly connected to the front and rear sides of the upper side wall of the upper partition 2. The support plates 22 support and fix the device, and the base box 23 at the bottom of the support plates 22 provides external protection for the hydraulic rods 24.

[0025] like Figure 1 - Figure 9As shown, a fixing block 25 is fixedly connected to the outer side of the telescopic end of each hydraulic rod 24. A first connecting rod 27 is fixedly connected to the inner side wall of each of the multiple support plates 22. A second connecting rod 28 is rotatably connected to the outer side of the other side of each first connecting rod 27. A first hinge frame 26 is fixedly connected to the upper side wall of each fixing block 25. A support rod 29 is rotatably connected inside each first hinge frame 26. A second hinge frame 30 is rotatably connected to the outer side of the other side of each support rod 29. The rear side wall of each second hinge frame 30 is fixedly connected to the front side wall of each second connecting rod 28. When the hydraulic rod 24 is activated, its telescopic end extends, causing the fixing block 25 to move backward. As the fixing block 25 moves backward, the first hinge frame 26 connected to it slides accordingly. Due to the support rod 29 rotatably connected inside the first hinge frame 26 and the second hinge frame 30 rotatably connected to the other end of the second connecting rod 28, the second connecting rod 28 changes angle as the first hinge frame 26 rises. At the same time, when the fixed block 25 slides, it drives the entire cleaning structure to move through the first connecting rod 27 and the rotatably connected second connecting rod 28.

[0026] Multiple second connecting rods 28 are connected to connecting posts 31 at their bottoms. Each connecting post 31 is fixedly connected to a fixing ring 32 at its rear end. A hose 33 is fixedly connected inside each fixing ring 32. The bottom ends of the hoses 33 are connected to a nozzle 34. The top ends of the hoses 33 pass through the interior of the upper partition 2 and are connected to the interior of the water tank plate 35. The hoses 33 are fixed inside the water tank plate 35 by the connecting posts 31 passing through the interior of the second connecting rods 28 and the fixing rings 32. The hoses 33 are fixed inside the water tank plate 35 by the rotation of the second connecting rods 28. The hoses 33 are adjusted in angle by the rotation of the second connecting rods 28. After the hoses 33 are adjusted, the cleaning fluid is sprayed out through the nozzles 34 at the bottom of the hoses 33 and sprays and rinses the upper guide plate 4, lower guide plate 5 and the outside of the tubes 8 inside the water tank plate 35. The cleaning fluid that enters the water tank plate 35 flows through the hoses 33 to the nozzles 34 and is sprayed out from the nozzles 34.

[0027] It should be noted that this utility model is a heat storage heat exchanger with recoverable waste heat. First, the hydraulic rod 24 is connected to an external power source and control panel to supply power to the device.

[0028] The hot fluid carrying residual heat flows in from the hot fluid inlet pipe 11 on the right side wall of the cylinder 1. The hot fluid first impacts the sieve plate 12, which initially filters out larger particles of impurities in the hot fluid, preventing them from entering the subsequent heat exchange area and causing blockages. After initial filtration, the hot fluid flows to the left, flowing within the tortuous channel formed by the intersection of multiple lower guide plates 5 and upper guide plates 4. The lower baffle plate 3 and upper baffle plate 2 restrict the flow of the hot fluid within a specific space, while the guide plates guide the hot fluid to flow around the tubes 8 in a tortuous path, increasing the residence time of the hot fluid in the cylinder and ensuring sufficient contact between the hot fluid and the tubes 8. The heat of the hot fluid is transferred to the cold fluid inside the tubes 8 through the tube wall, achieving initial heat exchange.

[0029] During the flow of the hot fluid, some denser impurities will settle downwards under gravity and fall into the impurity removal channel 13 inside the lower partition 3. Since the impurity removal channel 13 is correspondingly set with the impurity collection box 15, the impurities will fall into the impurity collection box 15 through the impurity removal channel 13. The guide plate 16 inside the impurity collection box 15 guides the impurities to concentrate near the discharge pipe 17. When it is necessary to clean the impurities, the baffle plate 18 is opened, and the impurities can be discharged through the discharge pipe 17. The baffle plate 18 is normally closed to prevent the impurities in the impurity collection box from overflowing. The hot fluid that has completed heat exchange and undergone impurity settling has a lower temperature and flows out of the heat exchanger from the hot fluid outlet pipe 14 on the left side of the bottom of the cylinder 1, and is discharged to the subsequent processing stage or directly discharged.

[0030] Low-temperature cold fluid flows in from the cold fluid inlet pipe 9 at the top left side of the cylinder 1. The cold fluid first enters the upper and lower spaces formed by the partition plate 7 and the baffle plate 6. Guided by the partition plate 7, the cold fluid enters the tube 8. Inside the tube 8, the cold fluid exchanges heat with the hot fluid flowing outside the tube, absorbing the heat transferred from the hot fluid, and its temperature gradually increases. Due to the guiding effect of the upper guide plate 4 and the lower guide plate 5 on the hot fluid, the cold fluid can efficiently exchange heat with the hot fluid with a large temperature difference and a long contact time when flowing inside the tube. After absorbing heat and heating up, the cold fluid flows out from the bottom of the tube 8, enters the space between the baffle plate 6 and the left side wall of the cylinder 1, and then flows out of the heat exchanger through the cold fluid outlet pipe 10. It can be transported to the process links or equipment that require heat energy to realize the recovery and utilization of waste heat.

[0031] The cleaning fluid is injected through the cleaning fluid inlet pipe 21 on the top right side of the cylinder 1. The injected cleaning fluid first flows into the water tank plates 35 on both sides of the upper sidewall of the upper partition plate 2 for temporary storage. The water tank plates serve to store and distribute the cleaning fluid. The cleaning fluid in the water tank plates 35 flows to the nozzle 34 through the hose 33 connected to the top. When the cleaning process is not started, the cleaning fluid is temporarily stored in the water tank plates 35 and the hose 33 connected to them, waiting for the cleaning command.

[0032] When the cleaning program is started, the hydraulic rod 24, located at the bottom of the support plate 22 and inside the base box 23, begins to operate. The telescopic end of the hydraulic rod 24 extends, causing the fixed block 25 to move backward. As the fixed block 25 moves backward, the first hinge frame 26 connected to it slides accordingly. Due to the rotatable support rod 29 inside the first hinge frame 26, and the second hinge frame 30 rotatably connected to the other end of the support rod 29, the second connecting rod 28 changes angle as the first hinge frame 26 slides. Simultaneously, the sliding of the fixed block 25, through the first connecting rod 27 and the rotatably connected second connecting rod 28, drives the entire cleaning structure to move. The connecting post 31, which is connected through the bottom of the second connecting rod 28, moves the fixed ring 32 and the connected hose 33 and nozzle 34 as the angle of the second connecting rod 28 changes. During the movement, the nozzle 34 gradually extends from its initial retracted state to its working position, allowing it to be aimed at the area to be cleaned, such as the tubes 8, the upper guide plate 4, and the lower guide plate 5.

[0033] Once the nozzle 34 is moved to the appropriate position, the cleaning fluid in the water tank plate 35 flows through the hose 33 to the nozzle 34 and is sprayed out from the nozzle 34. The cleaning fluid, with a certain pressure and angle, washes the outer wall of the tube 8, the upper guide plate 4, the lower guide plate 5, and other components, flushing off the impurities accumulated on the surface of these components. Some of the flushed impurities fall directly into the impurity removal tank 13 of the lower partition plate 3 under gravity and then enter the impurity collection box 15; others flow with the cleaning fluid and eventually collect in the impurity collection box 15.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
