Abstract
Description
Technical Field
[0001] This invention relates to the field of heat exchange technology, and more particularly to a tube bundle structure for a tubular heat exchanger. Background Technology
[0002] In the complex architecture of the globalized industrial system, tubular heat exchangers play a crucial role. As the core carrier of heat energy conversion, their continuous technological evolution and development directly relate to and profoundly influence the improvement of energy efficiency and the advancement of green industrial transformation. With the continuous rise in global energy costs and increasingly stringent environmental protection requirements, various industries have put forward more demanding and specific high standards for the heat transfer efficiency of tubular heat exchangers. In order to meet these requirements, it is necessary to further improve heat exchange efficiency and effectively reduce energy consumption by scientifically and rationally optimizing the tube bundle structure. This will enable the achievement of energy conservation and emission reduction goals while promoting the green and sustainable development of industries and contributing to environmental protection and efficient resource utilization.
[0003] Traditional tube bundle structures for tubular heat exchangers have several shortcomings. In applications with significant differences in medium flow rates on both sides, shell-and-tube heat exchangers lack flexibility in process flow configuration, making it difficult to achieve optimal heat transfer and pressure drop matching on both sides. Furthermore, the main flow direction in the shell side is generally perpendicular to the heat exchange tube axis, and the flow area along the circular cross-section constantly changes, resulting in poor flow uniformity in different regions. Short circuits and flow deviations are particularly prone to occur near the baffle notches, leading to low heat transfer efficiency. Existing floating head tube bundle structures offer flexibility, allowing the tube bundle to be removed from the shell for inspection, descaling, or replacement of damaged heat exchange tubes during maintenance and cleaning. However, this can easily lead to localized scaling and blockage in the shell side. Shell-side cleaning can only be performed after the tube bundle is removed, which is difficult and labor-intensive when the tube flow path is long. In corrosive environments, the tube bundle and shell are in direct contact with the medium, requiring the use of expensive corrosion-resistant metals, resulting in high equipment costs. Summary of the Invention
[0004] To overcome the above shortcomings, the present invention provides a tube bundle structure for a tubular heat exchanger, which aims to improve the problems of easy fouling and poor flow in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tubular heat exchanger tube bundle structure, including a heat exchanger pipe, an arc-shaped plate II provided at the bottom of the heat exchanger pipe, heat exchange mechanisms fixedly connected to both the left and right sides of the heat exchanger pipe, a support mechanism fixedly connected to the top of the arc-shaped plate II, the support mechanism being used for quick installation of the heat exchanger, the heat exchange mechanism including a receiving plate I, the left side of the receiving plate I being fixedly connected to the right side of the heat exchanger pipe, a receiving plate II provided on the right side of the receiving plate I, multiple fixing components rotatably connected to the middle of the receiving plate II, a hot water flow port fixedly connected to the right side of the receiving plate II, a fixing column I fixedly connected inside the heat exchanger pipe, a flow component fixedly connected to the outer wall of the fixing column I, multiple hot water conveying pipes slidably connected to the middle of the flow component, and a feeding component fixedly connected to the outer wall of the heat exchanger pipe.

[0019] The bottom of the knob is fixedly connected to an anti-slip sleeve, and the top of the base plate is provided with multiple screw holes.
[0020] The present invention has the following beneficial effects:
[0021] 1. In this invention, cold water enters through the cold water inlet and flows from right to left along the path of the spiral conveyor disc, exiting through the cold water outlet. The internal hot water delivery pipe carries hot water from the right to the left. The flow process achieves efficient heat exchange.

[0032] Specifically, an arc-shaped plate 4 is specially installed at the bottom of the heat exchanger pipe 1. This arc-shaped plate 4 enhances the structural stability and hydrodynamic performance of the pipe bottom. Heat exchange mechanisms 2 are firmly fixedly connected to both sides of the heat exchanger pipe 1. These heat exchange mechanisms 2 are the core components of the entire heat exchange system, responsible for achieving efficient heat transfer. Furthermore, a support mechanism 3 is fixedly connected to the top area of the arc-shaped plate 4. The main function of the support mechanism 3 is to facilitate quick installation and disassembly of the heat exchanger, greatly improving the maintenance efficiency and convenience of the equipment. In detail, the heat exchange mechanism 2 consists of multiple components, mainly including a receiving plate 201. The left side of the receiving plate 201 is fixedly connected to the right side wall of the heat exchanger pipe 1, ensuring its positional stability and heat transfer effectiveness. On the right side of the receiving plate 201, a receiving plate 202 is provided. Multiple fixed components are rotatably connected to the middle area of the receiving plate 202. Fixed components 203 allow the receiving plate 202 to rotate flexibly within a certain range, thereby optimizing the heat transfer path. In addition, a hot water flow port 204 is fixedly connected to the right side of the receiving plate 202.

A flow component 206 is further fixedly connected to the outer wall of the fixed column 205. Multiple hot water delivery pipes 207 are slidably connected to the middle area of the flow component 206. These hot water delivery pipes 207 ensure the uniform distribution and efficient flow of hot water. A feed component 208 is also fixedly connected to the outer wall of the heat exchanger pipe 1. The feed component 208 is mainly used to introduce the fluid to be heated into the heat exchanger pipe 1, thereby starting the entire heat exchange process. Through these structures, the entire heat exchanger system can operate efficiently and stably, meeting various heat exchange requirements.

[0034] Specifically, the support mechanism 3 is a complex structure composed of multiple parts to achieve its function. First, the support mechanism 3 includes a fixed column 301, which is the foundation of the entire support mechanism 3. Its bottom is fixedly connected to the rear side of the arc-shaped plate 4, thus ensuring the stability of the support mechanism 3. A rotating component 302 is fixedly connected to the top of the fixed column 301. This rotating component 302 is a very important part of the support mechanism 3 because it enables the rotation function of the support mechanism 3. A limit component 303 is rotatably connected to the front side of the rotating component 302. The function of this limiting component 303 is to limit the rotation angle of the support mechanism 3 to prevent excessive rotation from damaging the equipment. The limiting component 303 can precisely control the rotation range of the support mechanism 3 to ensure the safe operation of the equipment. In addition, a support column 304 is also fixedly connected to the bottom of the arc plate 4. The function of this support column 304 is to provide additional support force and enhance the stability of the entire support mechanism 3. The bottom of the support column 304 is fixedly connected to the base plate 305, which is the base of the entire support mechanism 3. It can be placed stably on the ground, providing a solid foundation for the entire support mechanism 3.

The feeding component 208 includes a cold water outlet 2081, the bottom of which is connected to the top of the outer wall of the heat exchanger pipe 1. The bottom of the outer wall of the heat exchanger pipe 1 is connected to a cold water inlet 2082.
[0036] Specifically, the fixing component 203 consists of a round screw 2031. The outer wall of the round screw 2031 is slidably connected to the center of the receiving plate 202, ensuring flexible movement during use. To the left of the round screw 2031, a bolt 2032 is fixed by a threaded connection. This connection method is both secure and easy to disassemble. In addition, the flow component 206 mainly consists of a threaded conveyor tray 2061. The central part of the threaded conveyor tray 2061 is firmly fixed to the fixing component. On the outer wall of column 205, to ensure its stability during operation, multiple circular holes 2062 are evenly opened in the middle of the threaded conveyor plate 2061. These holes improve the efficiency of material flow. As for the feeding component 208, it mainly includes a cold water outlet 2081. The bottom of the cold water outlet 2081 is connected to the top of the outer wall of the heat exchanger pipe 1 to ensure the smooth flow of cold water. At the same time, the bottom of the outer wall of the heat exchanger pipe 1 is also connected to a cold water inlet 2082 to realize the circulation of cold water and improve the heat exchange efficiency.
[0037] Please see the appendix Figure 3 - Appendix Figure 5 The rotating component 302 includes a rotating shaft 3021, the outer wall of which is rotatably connected to the top of the fixed column 301. An arc plate 3022 is fixedly connected to the middle of the outer wall of the rotating shaft 3021. The limiting component 303 includes a swing column 3031, the outer wall of which is rotatably connected to the front side of the arc plate 3022. A knob 3032 is threadedly connected to the outer wall of the swing column 3031. An anti-slip sleeve 5 is fixedly connected to the bottom of the knob 3032. Multiple screw holes 6 are provided on the top of the base plate 305.
[0038] Specifically, the rotating assembly 302 includes a rotating shaft 3021. The outer wall of the rotating shaft 3021 is rotatably connected to the top of the fixed column 301 to ensure free rotation. An arc-shaped plate 3022 is fixedly connected to the middle of the outer wall of the rotating shaft 3021. The arc-shaped plate 3022 is designed to provide stable support and connection. The limiting assembly 303 mainly consists of a swing column 3031. The outer wall of the swing column 3031 is rotatably connected to the arc-shaped plate 3021. The front side of 3022 allows it to swing within a certain range. A knob 3032 is installed on the outer wall of the swing column 3031 via a threaded connection. This knob 3032 is convenient for manual adjustment by the user. An anti-slip sleeve 5 is fixedly connected to the bottom of the knob 3032. The function of the anti-slip sleeve 5 is to increase the friction of the knob 3032 and prevent slippage during operation. In addition, multiple screw holes 6 are evenly opened on the top of the base plate 305. These screw holes 6 are used to fix other components to ensure the stability and firmness of the overall structure.
[0039] Working principle: Cold water enters through the cold water inlet 2082 and flows from right to left along the path of the threaded conveyor plate 2061, exiting through the cold water outlet 2081. Hot water flows through the internal hot water delivery pipe 207 from right to left. The flow process achieves efficient heat exchange. The spiral flow structure has higher heat transfer efficiency, lower resistance, and is less prone to scaling.
[0040] By clamping the heat exchanger pipe 1 with the arc plate 3022 and the arc plate 4, and bending the arc plate 3022 to let the swing column 3031 fall onto the opening on the front side of the arc plate 4, the arc plate 3022 and the arc plate 4 are fixed by turning the knob 3032, so that the heat exchanger pipe 1 in the middle is clamped, the bottom support column 304 firmly supports the column 304, and the base plate 305 is fixed with other plates. The installation steps can be completed quickly, which is convenient and labor-saving.
