Description

Technical Field

[0001] This invention relates to the field of heat exchanger equipment technology, specifically a vertical anti-clogging shell-and-tube heat exchanger. Background Technology

[0002] Shell-and-tube heat exchangers, as key equipment in industrial heat transfer, are widely used in chemical, energy, and refrigeration systems. Their performance directly affects heat conversion efficiency and operational stability. Traditional shell-and-tube heat exchangers typically use fixed-arrangement heat exchange tubes to exchange heat with the shell-side fluid. However, in practical applications, they often face challenges such as tube wear caused by vibration, localized blockage due to uneven medium flow, and leakage risks caused by mechanical vibration. Especially when handling fluids containing impurities or with high viscosity, traditional equipment lacks effective anti-clogging designs, easily leading to decreased heat exchange efficiency, increased maintenance frequency, and the rigid structure's inability to suppress resonance effects, further exacerbating equipment wear. While existing technologies attempt to alleviate these problems by optimizing tube layout or adding support structures, a synergistic optimization of anti-clogging, vibration reduction, and adaptive adjustment has not yet been achieved.

[0003] However, existing shell-and-tube heat exchangers still have significant technical shortcomings: First, traditional tube bundle support structures (such as baffles) are mostly rigid connections, which cannot effectively absorb equipment vibration energy, leading to resonant friction between the heat exchange tubes and the shell, accelerating tube wall wear and increasing the risk of leakage; Second, the lack of a dynamic anti-clogging mechanism makes it easy for impurities to accumulate in the shell-side fluid in low-velocity regions, especially under fluctuating flow conditions, making it difficult to avoid clogging through self-cleaning design; Third, fixed flow channel designs cannot adaptively adjust the heat exchange tube flux according to the medium flow rate, resulting in insufficient flow velocity in some tube bundles at low loads, exacerbating fouling accumulation; Fourth, traditional equipment lacks optimization of the flow path of hot and cold media, resulting in short medium residence time and limited heat exchange efficiency. These defects restrict the long-term stable operation and energy efficiency improvement of heat exchangers, and breakthroughs are urgently needed through the integration of elastic vibration reduction, dynamic anti-clogging, and flow adaptive technologies. Summary of the Invention

[0005] This invention provides a vertical, anti-clogging shell-and-tube heat exchanger that solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a vertical anti-clogging shell-and-tube heat exchanger, comprising a heat exchange tube, a top cover fixedly fastened to the top outer surface of the heat exchange tube, and a bottom cover fixedly connected to the bottom of the heat exchange tube, wherein the diameter of the heat exchange tube is smaller than that of the top cover and the bottom cover, and further comprising:

[0008] The conversion mechanism is fixedly installed inside the heat exchange tube;

[0009] An adaptive mechanism is fixedly installed inside the base cover and positioned directly below the conversion mechanism, with its top contacting and fitting against the bottom of the conversion mechanism.

[0010] The conversion mechanism includes a heat inlet pipe, which is fixedly connected to the top outer surface of the heat exchange tube. A heat outlet pipe is fixedly connected to the bottom outer surface of the heat exchange tube. A cold inlet pipe is fixedly connected to the outer surface of the bottom cover. A cold outlet pipe is fixedly connected to the outer surface of the top cover. Fixed plates are fixedly installed on the inner surfaces of both ends of the heat exchange tube. A connecting rod is fixedly connected to the surfaces of the two fixed plates that are close to each other. An exchange tube is fixedly connected to the outer surface of the fixed plate. Two sets of exchange tubes are provided, and the two sets of exchange tubes are symmetrically arranged. The two ends of the exchange tubes are respectively connected to the bottom cover and the top cover.

[0011] Preferably, the heat inlet pipe and the heat outlet pipe are arranged inside the fixed plate, and a first stabilizing plate is fixedly arranged on the inner surface of the heat exchange tube. The first stabilizing plate is fixedly sleeved on the outer surface of one group of heat exchange tubes, and four first stabilizing plates are arranged at fixed intervals along the inner surface of the heat exchange tube.

[0012] Preferably, a second stabilizing plate is fixedly installed on the inner surface of the heat exchange tube away from the first stabilizing plate. The second stabilizing plate is fixedly sleeved on the outer surface of another set of heat exchange tubes. Five second stabilizing plates are fixedly spaced along the inner surface of the heat exchange tube. The first and second stabilizing plates are fixedly connected to the fixed plate by a connecting rod.

[0013] Preferably, the first and second stabilizing plates are semi-circular and staggered. A rubber ring is fixedly connected to the outer surface of the fixed disk, and the outer side of the rubber ring is fixedly connected to the inner surface of the heat exchange tube.

[0014] Preferably, the adaptive mechanism includes a turbine, a rotating rod is fixedly connected to the middle of the turbine, and the bottom of the turbine is rotatably connected to the bottom inner surface of the base via the rotating rod. The turbine and the base are set to the same central axis, and the outer side of the turbine is positioned directly opposite the cooling inlet pipe.

[0015] Preferably, an isolation ring is fixedly connected to the upper surface edge of the turbine, the isolation ring is disposed above the cooling inlet pipe, the side surface of the isolation ring is rotatably connected to the middle inner surface of the bottom cover, and the inner diameter of the isolation ring is smaller than the diameter of the turbine.

[0016] Preferably, a first plug rod is provided above the turbine. The first plug rod is arc-shaped, and plug grooves are provided on both sides of the first plug rod.

When this heat exchanger is needed, the cold medium can be introduced from the cold inlet pipe, and the hot medium can be introduced from the heat inlet pipe simultaneously. After the cold medium enters the bottom cover, it will be transported through the exchange tube and then enter the top cover, and finally exit through the cold outlet pipe. After the hot medium enters the heat exchange tube, it will be transported from the top to the bottom of the heat exchange tube, contacting the outer surface of the heat exchange tube during the process to complete the heat exchange operation, and finally exit through the heat outlet pipe at the bottom.

[0019] (III) Beneficial Effects

[0020] This invention provides a vertical, anti-clogging shell-and-tube heat exchanger. It offers the following advantages:

[0021] (I) This vertical, anti-clogging shell-and-tube heat exchanger isolates the exchange tubes by inserting them between the No. 1 and No. 2 stabilizing plates. This ensures the exchange tubes are in a relatively dispersed state during operation, avoiding the risk of leakage due to friction between the tubes caused by equipment vibration. Furthermore, after the hot medium enters the heat exchange tubes, the staggered arrangement between the No. 1 and No. 2 stabilizing plates causes the hot medium to flow in an S-shape towards the bottom within the heat exchange tubes, significantly increasing the residence time of the hot medium and thus greatly improving the heat exchange effect. During the heat exchange process of the cold medium passing through the exchange tubes, due to the No. 1 stabilizing plate… The first and second stabilizing plates are connected to the fixed plate as a whole via a connecting rod. The rubber ring allows the first, second, and fixed plates to have a certain range of motion. This greatly reduces the vibration generated by the equipment body during operation when it is transmitted to the first, second, and fixed plates, thereby significantly reducing the possibility of resonance between the heat exchange tube and the equipment. This protects the heat exchange tube and prevents it from rupturing and leaking due to frequent resonance with the equipment during operation. It also significantly improves the service life of the heat exchanger and enhances its operational stability.

[0022] (II) In this vertical anti-clogging shell-and-tube heat exchanger, the cold medium is continuously sprayed onto the turbine through the inlet pipe when it enters the bottom cover. The turbine is automatically driven to rotate when the cold medium enters the bottom cover. The rotation of the turbine keeps the cold medium in the bottom cover in a constant state of motion, avoiding the problem of pressure dead zones and impurity accumulation that would eventually cause blockage of the heat exchanger after the cold medium enters the bottom cover. This further improves the service life of the heat exchanger. In addition, the isolation ring ensures that the cold medium can only be transported through the gap between the turbine blades when it first enters the bottom cover, thereby increasing the impact force of the cold medium on the turbine. This ensures that the turbine can still be driven to work under low flow heat exchange conditions, which greatly improves the applicability of the heat exchanger.

[0023] (III) This vertical anti-clogging shell-and-tube heat exchanger automatically adjusts its turbine speed to match the varying impact forces exerted on the turbine by different flow rates of cold medium. When the turbine rotates, it drives the connecting seat to rotate via a rotating rod. The rotation of the connecting seat, in turn, drives the counterweight to rotate along the inner groove of the first insertion rod via the second telescopic rod. The different centrifugal forces generated by the turbine speed also automatically adapt to the impact force exerted on the outer side of the counterweight during rotation. This allows the opening and closing cavity between the first and second insertion rods to adaptively change according to different flow rates, thereby automatically controlling the number of openings and closings of the exchange tubes. This ensures that the cold medium always maintains its optimal operating temperature under varying flow rates. The flow pattern, via the exchange pipes, avoids the blockage caused by insufficient pressure in some exchange pipes leading to prolonged accumulation of cold medium when the flow rate is low but the number of exchange pipes is large. When the counterweight is rotating, the friction strips on the inner side of the first connector rod cause the counterweight to intermittently contact the friction strips, thereby intermittently increasing the friction between the counterweight and the first connector rod. This intermittently limits the rotational speed of the counterweight, thus controlling the turbine's rotational speed. This makes the operation between the first and second connector rods and the counterweight more stable, preventing the counterweight and turbine from exceeding their load limits and causing loss of control.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] First embodiment: as follows Figures 1 to 8 As shown, the present invention provides a technical solution: a vertical anti-clogging shell-and-tube heat exchanger, including a heat exchange tube 1, a top cover 2 fixedly fastened to the top outer surface of the heat exchange tube 1, and a bottom cover 3 fixedly connected to the bottom of the heat exchange tube 1.

The first stabilizing plate 48 and the second stabilizing plate 49 are fixedly connected to the fixed plate 45 through the connecting rod 46.

[0040] The first stabilizing plate 48 and the second stabilizing plate 49 are set as semi-circles, and the first stabilizing plate 48 and the second stabilizing plate 49 are staggered. A rubber ring 410 is fixedly connected to the outer surface of the fixed plate 45. The outer side of the rubber ring 410 is fixedly connected to the inner surface of the heat exchange tube 1. The outer surfaces of the first stabilizing plate 48 and the second stabilizing plate 49 are also fixedly connected to the rubber ring 410.

[0041] Second embodiment: as follows Figures 1 to 8 As shown, the adaptive mechanism 5 includes a turbine 51, a rotating rod 52 is fixedly connected to the middle of the turbine 51, and the bottom of the turbine 51 is rotatably connected to the bottom inner surface of the bottom cover 3 through the rotating rod 52. The turbine 51 and the bottom cover 3 are set to the same central axis, and the outer side of the turbine 51 is set to face the cooling pipe 43.

[0042] An isolation ring 53 is fixedly connected to the upper surface edge of the turbine 51. The isolation ring 53 is located above the cooling pipe 43. The side surface of the isolation ring 53 is rotatably connected to the middle inner surface of the bottom cover 3. The inner diameter of the isolation ring 53 is smaller than the diameter of the turbine 51.

[0043] A first plug rod 54 is provided above the turbine 51. The first plug rod 54 is arc-shaped, and plug grooves 55 are provided on both sides of the first plug rod 54. A second plug rod 56 is slidably inserted into the plug grooves 55. The first plug rod 54 and the second plug rod 56 are combined to form a ring.

[0044] A telescopic rod 57 is fixedly connected to the outer surface of the second connector rod 56. The first telescopic rod 57 is elastic, and the end of the first telescopic rod 57 away from the second connector rod 56 is fixedly connected to the inner surface of the bottom cover 3.

[0045] A groove 58 is provided on the inner surface of the first plug rod 54. A counterweight 59 is slidably connected in the groove 58. A second telescopic rod 510 is fixedly connected to the inner surface of the counterweight 59. A connecting seat 511 is fixedly connected to the end of the second telescopic rod 510 away from the counterweight 59. The bottom surface of the connecting seat 511 is fixedly connected to the top of the rotating rod 52. Three counterweights 59 are fixedly spaced along the central axis of the connecting seat 511. A friction strip 512 is fixedly embedded in the inner side of the first plug rod 54. An isolation membrane 513 is fixedly connected to the bottom surface of the first plug rod 54. The isolation membrane 513 is annular. The outer end of the isolation membrane 513 is fixedly connected to the inner surface of the bottom cover 3.

[0046] During operation, when this heat exchanger is needed, the cold medium can be introduced through the cold inlet pipe 43, and the hot medium can be introduced simultaneously through the hot inlet pipe 41. After entering the bottom cover 3, the cold medium will be distributed and transported through the exchange pipe 47 into the top cover 2, and finally discharged through the cold outlet pipe 44. The hot medium enters the heat exchange pipe 1 and is transported from the top to the bottom of the heat exchange pipe 1, during which it contacts the outer surface of the exchange pipe 47 to complete the heat exchange operation, and finally discharged through the bottom heat outlet pipe 42. The exchange pipe 47 is isolated and inserted on the first stabilizing plate 48 and the second stabilizing plate 49, so that the exchange pipe 47 is in a relatively dispersed state during operation, avoiding the risk of leakage caused by friction between the exchange pipes 47 due to equipment vibration. After entering the heat exchange tube 1, the staggered arrangement between the first stabilizing plate 48 and the second stabilizing plate 49 causes the heat medium to be transported to the bottom in an S-shape within the heat exchange tube 1, significantly increasing the residence time of the heat medium in the heat exchange tube 1 and thus greatly improving the heat exchange effect. During the heat exchange process of the cold medium through the exchange tube 47, since the first stabilizing plate 48 and the second stabilizing plate 49 are connected to the fixed plate 45 as a whole by the connecting rod 46, and the rubber ring 410 allows the first stabilizing plate 48, the second stabilizing plate 49 and the fixed plate 45 to have a certain range of motion, the vibration generated by the equipment body during operation is greatly reduced when it reaches the first stabilizing plate 48, the second stabilizing plate 49 and the fixed plate 45, thereby significantly reducing the vibration between the exchange tube 47 and the equipment. The possibility of resonance between the components is reduced, thus protecting the exchange tube 47 and preventing it from frequently resonating with the equipment during operation, which could lead to rupture and leakage. This also significantly improves the service life and operational stability of the heat exchanger. When the cold medium enters the bottom cover 3, it continuously flows onto the turbine 51 through the cooling inlet pipe 43. The cooling inlet pipe 43 automatically drives the turbine 51 to rotate, keeping the cold medium in the bottom cover 3 in constant motion. This prevents pressure dead zones and impurity buildup that could eventually clog the heat exchanger, further extending its service life. Furthermore, the isolation ring 53 ensures that the cold medium is constantly in motion upon entering the bottom cover 3. The internal flow can only be transported through the gaps between the blades of turbine 51, thereby increasing the impact force of the cold medium on turbine 51. This ensures that turbine 51 can still be driven to work under low flow heat exchange conditions, greatly improving the applicability of this heat exchanger. As the impact force of the cold medium on turbine 51 varies with different flow rates, the rotation speed of turbine 51 will automatically match. When turbine 51 rotates, it will drive connecting seat 511 to rotate via rotating rod 52. When connecting seat 511 starts to rotate, it will drive counterweight 59 to start rotating along the sliding groove 58 on the inner side of first insertion rod 54 via second telescopic rod 510. Moreover, the centrifugal force generated by turbine 51 varies with different rotation speeds, so the counterweight 59 will automatically adapt to the impact force on the outer side when rotating.This allows the opening and closing cavity between connector 54 and connector 56 to adaptively change according to different flow rates, thereby automatically controlling the number of openings and closings of the exchange pipes 47. This ensures that the cold medium always flows through the exchange pipes 47 under different flow rates, preventing insufficient pressure in some exchange pipes 47 when the flow rate is low but the number of exchange pipes 47 is large, which could lead to blockages caused by prolonged accumulation of cold medium. When the counterweight 59 is rotating, the friction strip 512 on the inner side of connector 54 intermittently contacts the counterweight 59, thus intermittently increasing the friction between the counterweight 59 and connector 54. This intermittently limits the rotational speed of the counterweight 59, i.e., controls the rotational speed of the turbine 51. This makes the operation between connectors 54 and connector 56 and the counterweight 59 more stable, preventing the counterweight 59 and turbine 51 from exceeding their load and causing loss of control.
