Abstract
Description
Technical Field
[0001] This utility model relates to the field of shell-and-tube condenser technology, and in particular to a shell-side zoned flow-guided shell-and-tube condenser. Background Technology
[0002] Shell-and-tube condensers are commonly used heat exchange equipment in industrial production and are widely used in chemical, petroleum, and refrigeration fields. They are mainly used to cool and condense gaseous substances into liquids. The cooling effect is achieved through heat exchange between different media in the tube side and shell side. They are characterized by strong applicability, stable operation, and moderate processing capacity. They can adapt to various working conditions and media types. In the process flow, they play a key role in heat recovery and media state conversion. They are one of the important equipment to ensure continuous production and improve energy efficiency.
[0003] During the operation of a shell-and-tube condenser, the flow state of the medium to be condensed in the shell side directly affects the heat exchange efficiency. Traditional shell-and-tube condensers often use fixed baffles to divide the flow channels in the shell side to enhance heat exchange. However, fixed baffles cannot adjust the flow channel space according to changes in the cooling water flow rate in the tube side. When the cooling water flow rate increases, the flow resistance of the medium in the shell side increases, which easily leads to uneven local flow velocity, resulting in limited improvement in heat exchange efficiency and difficulty in adapting to the heat exchange requirements under fluctuating flow scenarios. Therefore, a shell-side partitioned flow-guided shell-and-tube condenser is needed. Utility Model Content
[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a shell-side partitioned flow-guided tube condenser that can solve the problem that the fixed baffle in the tube condenser cannot adjust the shell-side flow channel space according to the change of cooling water flow, resulting in increased shell-side medium flow resistance and uneven flow velocity when the flow rate increases, which in turn limits the improvement of heat exchange efficiency and makes it unable to adapt to the flow fluctuation conditions.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a shell-side partitioned flow-guiding tubular condenser, comprising a tubular condenser and a flow rate adaptation and adjustment plate structure. The flow rate adaptation and adjustment plate structure includes partition baffles, movable baffles, fixing members, connecting members, rotating rod A, and rotating rod B. Multiple partition baffles are equidistantly fixedly connected inside the tubular condenser, with each partition baffle arranged alternately vertically. The number of movable baffles is the same as the number of partition baffles, and they are slidably connected to the corresponding partition baffle surfaces. The fixing members are fixedly connected to the surfaces of the movable baffles, and the connecting members are fixedly connected to the surfaces of the partition baffles. Rotating rod A is rotatably connected to the surface of the connecting member, and rotating rod B is slidably connected inside rotating rod A. The end of rotating rod B closest to the fixing member is rotatably connected to the fixing member. A return spring is fixedly connected inside rotating rod A, and the return spring is fixedly connected to rotating rod B.
[0006] Preferably, the shell-and-tube condenser has two partition plates fixedly connected inside, and multiple pipe structures are fixedly connected to the surfaces of the two partition plates. Each partition baffle is fixedly connected to the pipe structure, and each movable baffle is slidably connected to the pipe structure.
[0007] Preferably, both sides of the shell-and-tube condenser are movably connected to detachable end caps, and each detachable end cap is fixedly connected to a flow pipe on its surface. The two flow pipes are connected through multiple pipe structures.
[0008] Preferably, the bottom of the shell-and-tube condenser is fixedly connected to a water inlet pipe, and the top of the shell-and-tube condenser is fixedly connected to a water outlet pipe, with the water inlet pipe connected to the water outlet pipe through the shell-and-tube condenser.
[0009] Preferably, the bottom of the shell-and-tube condenser is fixedly connected to a support frame, and the bottom of the support frame is fixedly connected to a base.
[0010] Preferably, the surfaces of the partition baffle and the movable baffle are provided with a plurality of openings that allow the pipe structure to pass through.
[0011] Preferably, the pipe structure can be a smooth circular pipe.
[0012] Preferably, the pipe structure can also be a circular pipe with spiral grooves on its surface.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This shell-side partitioned flow-guided tubular condenser features a flow rate adaptive adjustment plate structure. This structure achieves adaptive adjustment of the flow channel space through the cooperation of partition baffles and movable baffles. The partition baffles are fixed at equal intervals and staggered vertically, effectively dividing the shell-side flow channel and guiding the medium flow. The movable baffle is slidably connected to the partition baffles, forming an elastic adjustment mechanism through a rotating rod assembly and a return spring. When the cooling water flow rate increases, the movable baffle is impacted by the water flow and moves away from the partition baffle, increasing the shell-side flow space to reduce resistance. After the flow rate recovers, the return spring drives the movable baffle to reset, ensuring flow channel stability. This structure requires no additional driving components, achieving adaptive matching between flow rate and flow channel, improving heat exchange stability under different operating conditions. Furthermore, its compact structure fits tightly with the piping structure and does not affect the overall operational reliability of the condenser. Attached Figure Description

[0027] Please see Figure 1-6This utility model provides a technical solution: a shell-side partitioned flow-guided tube condenser, wherein:
[0028] The bottom of the shell-and-tube condenser 1 is fixedly connected to the support frame 6, and the bottom of the support frame 6 is fixedly connected to the base 7. The three are joined together by welding. The base 7 is made of cast iron to enhance stability, and the support frame 6 is made of stainless steel to improve load-bearing capacity. Together, they provide stable support for the condenser as a whole.
[0029] The shell-and-tube condenser 1 is movably connected to the removable end caps 2 on both sides. The surface of the removable end caps 2 is fixedly connected to the flow pipes 3. The two flow pipes 3 are connected through multiple pipe structures 9. The removable end caps 2 are bolted to the condenser body for easy disassembly and maintenance. The flow pipes 3 are made of seamless steel pipe to reduce the resistance to medium flow.
[0030] The shell-and-tube condenser 1 is fixedly connected to two partition plates 8 inside. The surface of the partition plates 8 is fixedly connected to multiple pipe structures 9. The pipe structures 9 can be smooth round pipes or round pipes with spiral grooves on the surface. The partition plates 8 are made of steel plates and are welded to the inner wall of the condenser and the pipe structures 9 to achieve pipe positioning and internal space division.
[0031] The partition baffles 10 are all fixed at equal intervals inside the shell-and-tube condenser 1 and are fixedly connected to the pipe structure 9. The number of movable baffles 11 is the same as that of the partition baffles 10 and they are slidably connected to the surface of the partition baffles 10. Both of them have openings 12 that allow the pipe structure 9 to pass through. They are made of stainless steel to ensure wear resistance and corrosion resistance. The openings 12 achieve precise matching with the pipe structure 9.
[0032] The surface of the movable baffle 11 is fixedly connected to the fixing member 13, the surface of the partition baffle 10 is fixedly connected to the connecting member 14, the rotating rod A15 is rotatably connected to the surface of the connecting member 14, the rotating rod B16 is slidably connected inside the rotating rod A15, and the end of the rotating rod B16 near the fixing member 13 is rotatably connected to the fixing member 13. Both the fixing member 13 and the connecting member 14 are steel components, which are fixed to the baffles by bolts to ensure the stable operation of the rotating assembly.
[0033] The rotating rod A15 is fixedly connected to the return spring 17, which is fixedly connected to the rotating rod B16. The return spring 17 is made of stainless steel spring steel to improve its elastic return performance. It works with the rotating rod AB to form an elastic adjustment mechanism, thereby realizing the automatic reset of the movable baffle 11 and improving the heat exchange stability under different working conditions.
[0034] The bottom of the shell-and-tube condenser 1 is fixedly connected to the inlet pipe 4, and the top is fixedly connected to the outlet pipe 5. The inlet pipe 4 is connected to the outlet pipe 5 through the shell-and-tube condenser 1. Both the inlet pipe 4 and the outlet pipe 5 are made of seamless steel pipes and are welded to the condenser body to ensure the sealing and flow of the cooling water circulation channel.
[0035] Working principle: When the shell-and-tube condenser 1 is working, cooling water enters through the inlet pipe 4, passes through the outside of the pipe structure 9 fixed by the partition plate 8, and is discharged from the outlet pipe 5. After the cooling water enters the tube side through the flow pipe 3 of the removable end cover 2, it exchanges heat with the pipe structure 9 and then condenses. The support frame 6 and the base 7 provide support. The partition plate 10 is fixed inside the shell side and fixed to the pipe structure 9. The movable baffle 11 slides on the partition plate 10 and cooperates with the pipe structure 9. The rotating rods A15 and B16 are connected by the connector 14 and the fixing part 13. The return spring 17 is installed in the rotating rod A15 and connected to the rotating rod B16. When the water flow is large, the water flow impacts the movable baffle 11, causing it to move away from the partition plate 10. This pulls the rotating rod B16 and stretches the return spring 17, increasing the flow space in the shell side to adapt to heat exchange. After the flow is normal, the return spring 17 returns to its original position, causing the movable baffle 11 to reattach to the partition plate 10, ensuring stable heat exchange.
[0036] Example 1: (Reference) Figure 2 )
[0037] The pipe structure 9 adopts a smooth circular pipe. The inner wall of this type of pipe structure 9 is smooth and without protrusions. When it is fixedly connected with the partition plate 8, the fit is high. When passing through the openings 12 on the surface of the partition baffle 10 and the movable baffle 11, the frictional resistance is small, which facilitates installation and subsequent maintenance. When the condensing medium flows in the tube, it is not easy to accumulate scale, and it can maintain a long-term stable flow efficiency. At the same time, the smooth inner wall reduces the energy consumption of the medium flow. In conjunction with the circulation channel formed by the inlet pipe 4 and the outlet pipe 5, the cooling water heat exchange is more uniform. With the flow rate adaptation adjustment plate structure, it can still maintain a good heat exchange effect under the condition of flow fluctuation, effectively improving the economy and stability of condenser operation.
[0038] Example 2: (Reference) Figure 4 )
[0039] The pipe structure 9 adopts a circular tube with spiral grooves on its surface. This type of pipe structure 9 increases the contact area with the cooling water in the tube side and the medium to be condensed in the shell side through the spiral grooves, which enhances the heat transfer effect. The groove structure can promote the formation of turbulence in the medium, reduce the thickness of the heat transfer boundary layer, and improve the heat transfer coefficient. It also has a tighter fit with the partition baffle 10 and the movable baffle 11. When the water flow impacts the movable baffle 11 to adjust the flow channel, the spiral grooves can further optimize the flow state of the medium and avoid local dead zones. Even under high-load heat exchange scenarios, the heat exchange efficiency can be guaranteed through structural cooperation, and the service life of the pipe structure 9 can be extended.
[0040] Example 3: (Reference) Figure 1-6 )
[0041] The smooth circular tube pipe structure 9 is suitable for scenarios with high media cleanliness and strict requirements for flow resistance, such as steam condensation in the food processing industry and precision instrument cooling systems. In these scenarios, the media is less prone to impurity deposition, and the smooth inner wall can meet the requirements of low energy consumption and easy maintenance. The circular tube pipe structure 9 with spiral grooves on the surface is suitable for scenarios with high heat exchange efficiency requirements, such as high temperature and high pressure media condensation in chemical production and waste heat recovery from industrial boiler exhaust gas. In these scenarios, rapid heat transfer is required, and the spiral groove structure can significantly improve heat transfer performance and adapt to the application needs of different industries.
[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
