Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, specifically relating to a detachable distributed structure for a heat exchanger. Background Technology

[0002] The multiple perforated distribution plates inside the lower shell of the heat exchanger primarily serve the following functions: They distribute the fluid entering the lower shell evenly across the entire flow cross-section through a porous structure, preventing excessively high or low flow rates in certain areas, ensuring sufficient contact between the heat exchange medium and the heat transfer surface, guiding the fluid to form an axial flow pattern, reducing turbulent dead zones, and improving heat exchange efficiency. The physical barrier effect of the perforated distribution plates prevents the fluid from flowing directly along the shell wall or central area (i.e., "short-circuiting"), forcing the fluid to pass through the heat exchange area along the designed path. The perforated plates also act as a support frame within the shell side, fixing the tube bundle or filter assembly and preventing structural displacement due to vibration during equipment operation. The layered distribution plates disperse the impact force of the shell-side fluid, reducing the risk of localized stress concentration. Furthermore, through gradient pore design and multi-layer arrangement, the fluid velocity is gradually reduced and pressure distribution is adjusted, balancing overall pressure drop and heat transfer performance. Special pore types (such as converging orifices or guide holes) reduce flow resistance and match the requirements of media with different viscosities.

[0003] In summary, the function of the distribution plate with distribution holes has been explained, and different types of distribution holes can achieve different effects. However, after on-site inspection, the applicant found that the current technology of installing the distribution plate is to install it in the lower shell of the heat exchanger by welding. This installation method is not easy to support replacement and maintenance, so further improvement and optimization are needed. Utility Model Content

[0004] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a detachable distributed structure for heat exchangers.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A detachable distribution structure for a heat exchanger includes a lower cylinder, one of the components of the heat exchanger. The lower cylinder has multiple pipe interfaces and multiple arc-shaped support plates on its inner wall. Each arc-shaped support plate has a mounting hole at its center. The arc-shaped support plates are evenly spaced on the inner wall of the lower cylinder, forming multiple horizontal mounting surfaces longitudinally. All arc-shaped support plates on the same horizontal surface are fitted with distribution plates. Each distribution plate has skirt plates corresponding to the number of arc-shaped support plates on one horizontal surface. Each skirt plate has a first through hole. A sealing ring is installed on the upper side of each distribution plate, and the sealing ring has a second through hole.

[0007] Furthermore, the distribution plate has at least three parts, and the distribution holes on each distribution plate are evenly distributed at different positions. The distribution holes are more densely distributed on the distribution plates at higher positions. This design, with its progressive arrangement, ensures the distribution effect while reducing the flow equalization pressure on the distribution plates.

[0008] Furthermore, the distribution plate located at the top is a complete circle. This design eliminates the need for openings because it does not require sunk installation, thus reducing production difficulty.

[0009] Furthermore, there are at least four of the aforementioned arc-shaped support plates on the same horizontal plane; this design ensures installation strength.

[0010] Furthermore, the width of the sealing ring is greater than the width of the arc-shaped support plate, a design that ensures a good sealing effect.

[0011] The beneficial effects of using this utility model are as follows:

[0012] With the structural design of this utility model, the distribution plate is installed on the arc-shaped support plate by screws. With the effect of the skirt plate, the distribution plate can be rotated to avoid the arc-shaped support plate and install the distribution plate at a lower position. The same applies to disassembly.

[0013] The structural design of this utility model, compared to the welding installation method, makes it possible to disassemble the distribution plate by means of screw connection. This allows for better installation of distribution plates of different specifications and hole types according to needs, thus ensuring the performance of the heat exchanger.

[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1-4 As shown, the present invention discloses a detachable distribution structure for a heat exchanger, comprising a lower cylinder 1, one of the components of the heat exchanger. The lower cylinder 1 is provided with multiple pipe interfaces 2, and multiple arc-shaped support plates 3 are provided on the inner wall of the lower cylinder 1. The arc-shaped support plates 3 are provided with mounting holes 4 in the middle position. The arc-shaped support plates 3 are evenly arranged on the inner wall of the lower cylinder 1 at intervals, and the arc-shaped support plates 3 form multiple horizontal mounting surfaces longitudinally. All arc-shaped support plates 3 on the same horizontal surface are together equipped with distribution plates 5. The distribution plates 5 are provided with skirt plates 6 corresponding to the number of arc-shaped support plates 3 on one horizontal surface. The skirt plates 6 are provided with first through holes 7. A sealing ring 8 is installed on the upper side of the distribution plate 5, and the sealing ring 8 is provided with second through holes 9.

[0023] In this implementation case, when using a detachable distribution structure for a heat exchanger, the arc-shaped support plate 3 is fixedly installed in the lower cylinder 1, and then the distribution plate 5 can be installed.

[0024] In the lower cylinder 1, the distribution plates 5 are installed from bottom to top, and the density of the distribution holes on the lower distribution plates 5 is greater, thereby reducing the impact pressure on the distribution plates 5 when in contact with the airflow. Under the effect of the skirt plate 6, the arc support plate 3 can pass through the gap between two adjacent skirt plates 6, so it can ensure that the distribution plates 5 move down into place. After the distribution plates 5 reach the required position, they are rotated horizontally so that the skirt plate 6 is located on the arc support plate 3. At this time, the placement of the distribution plates 5 is completed. Then, the sealing ring 8 is placed on the distribution plates 5. Under the effect of the sealing ring 8, the gap between two adjacent arc support plates 3 is sealed, so that the airflow or water flow must pass through the distribution holes on the distribution plates 5. Then, the distribution plates 5 are fixed and installed by screws through the second through hole 9, the first through hole 7 and the mounting hole 4. Multiple distribution plates 5 are installed in this way.

[0025] When disassembly is required, simply remove the screws and rotate the distribution plate 5 so that the skirt plate 6 passes through the gap between two adjacent arc-shaped support plates 3 to remove the distribution plate 5.

[0026] It is preferred that there are at least three distribution plates 5, and the distribution holes on each distribution plate 5 are evenly distributed in different positions. The distribution holes of the distribution plates 5 are more dense as they are higher up. This design is progressive and ensures the distribution effect while reducing the flow equalization pressure of the distribution plates 5. In fact, the number of distribution plates 5 and the diameter of the distribution holes can also be customized according to the specific situation.

[0027] The preferred design is that the distribution plate 5 located at the top is a complete circle. This design eliminates the need for sinking installation and therefore eliminates the need for openings, reducing production difficulty. In fact, measures to reduce production difficulty can also be considered depending on the specific circumstances.

[0028] Ideally, there should be at least four arc-shaped support plates 3 on the same horizontal plane. This design ensures installation strength. In practice, the number of arc-shaped support plates 3 can also be considered according to specific circumstances.

[0029] Preferably, the width of the sealing ring 8 is greater than the width of the arc-shaped support plate 3. This design ensures a good sealing effect. In practice, the width of the sealing ring 8 and the sealing measures can also be considered according to specific circumstances.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
