Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchange technology, and in particular to a heat exchange device for an ultrapure water system. Background Technology
[0002] The heat exchanger for ultrapure water systems is a precision heat exchange device designed specifically for high-purity water treatment processes, and is mainly used in industries with extremely high water quality requirements.
[0003] In ultrapure water heat exchange systems, shell-and-tube heat exchangers are typically used. Highly efficient heat exchange is achieved by having ultrapure water and the heat transfer medium flow counter-currently in the tube and shell sides, respectively. Traditionally, heat exchangers are rigidly fixed to the ground or support using bolts during installation. However, in actual operation, when high-pressure ultrapure water flows through the heat exchange tube bundle at a high velocity (typically 2-5 m / s), significant hydraulic pulsations and turbulent vibrations occur. Simultaneously, the phase change process of the heat transfer medium in the shell side also causes internal pressure fluctuations. These periodic fluid excitations lead to mechanical vibrations throughout the heat exchanger, which are transmitted to the fixing bolts through the rigid connection structure. Over long-term operation, this vibration causes the bolts to gradually rotate slightly, resulting in a decrease in preload and even visible thread slippage.
[0004] Therefore, this solution proposes a heat exchange device for ultrapure water systems to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a heat exchange device for an ultrapure water system to solve the problems mentioned in the background art.

[0018] The technical effects and advantages of this utility model are as follows:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figure 1-4 A heat exchange device for an ultrapure water system, as shown, includes:
[0027] Heat exchange component 1;
[0028] The first mounting bracket 2 is located at the bottom of the heat exchange assembly 1;
[0029] The second mounting bracket 3 is located at the bottom of the heat exchange component 1. The second mounting bracket 3 and the first mounting bracket 2 are arranged horizontally and symmetrically. Mounting holes are provided in the middle of both the first mounting bracket 2 and the second mounting bracket 3.
[0030] Pressing blocks 4, multiple pressing blocks 4 are respectively set on the top of the first mounting frame 2 and the second mounting frame 3, and a rubber pad 6 is set on the bottom of the pressing blocks 4;
[0031] Movable component 5 is located on top of pressing block 4 and is used to move the position of pressing block 4.
[0032] It should be noted that the first mounting bracket 2 and the second mounting bracket 3 are identical in shape, with both having an L-shaped horizontal longitudinal section. Mounting holes are provided at the bottom of both mounting brackets for bolts to pass through. In use, the bolts are first passed through the two mounting brackets, and then the moving component 5 moves the pressing block 4 and the rubber pad 6 to the top of the bolt. The pressing of the pressing block 4 and the rubber pad 6 causes the elastic deformation of the rubber pad 6 to create a larger contact area and micro-engagement between it and the bolt head, increasing the friction of the bolt and reducing the occurrence of bolt rotation. This prevents the connection of the device from becoming loose due to bolt rotation during use.
[0033] Specifically, the heat exchange assembly 1 includes a main pipe 102, the bottom of which is fixedly connected to the top of the first mounting bracket 2 and the second mounting bracket 3. Both the top and bottom of the main pipe 102 are provided with connecting pipes 101. Multiple heat exchange tubes 103 are inserted and connected inside the main pipe 102. At the connection between the main pipe 102 and the heat exchange tubes 103, there are fixing components for fixing the position of the heat exchange tubes 103. The fixing components include sealing plates 105 that are symmetrically fixedly connected to both ends of the heat exchange tubes 103. Multiple sealing plates 105 are fixedly connected to both sides of the main pipe 102 respectively. Multiple through holes 104 are opened on one side of the sealing plate 105.
[0034] It should be noted that there are two connecting pipes 101, which are respectively set at the top and bottom of the main pipe 102, and the two connecting pipes 101 are interconnected with the main pipe 102, so that the medium can enter the interior of the main pipe 102 through one of the connecting pipes 101 and flow out from the other connecting pipe 101; there are two sealing plates 105, which are used to seal the two sides of the main pipe 102 to prevent the medium inside the main pipe 102 from flowing out from the two sides of the main pipe 102. A heat exchange tube 103 is fixedly connected to one side of the sealing plate 105 with a through hole 104, so that ultrapure water can enter the interior of the heat exchange tube 103 through the through hole 104 during use.
[0035] Furthermore, during use, the two connecting pipes 101 are connected to the heat medium pipeline, and the two sides of the main pipe 102 are connected to the ultrapure water pipeline. The heat medium enters the interior of the main pipe 102 through one of the connecting pipes 101, and the ultrapure water enters the heat exchange tube 103 through the through hole 104, where heat exchange takes place inside the main pipe 102.
[0036] Specifically, the movable component 5 includes a slider 506 fixedly connected to the top of the pressing block 4. A bidirectional screw 504 is threaded through the middle of the slider 506. The bidirectional screw 504 is threaded through the top of the first mounting bracket 2. A torsion cap 501 is fixedly connected to one end of the bidirectional screw 504. A fixed bearing 507 is fixedly connected to one side of the second mounting bracket 3. The fixed bearing 507 is sleeved on the other end of the bidirectional screw 504. A limiting rod 505 is fixedly connected to the side of the first mounting bracket 2 opposite to the second mounting bracket 3. The limiting rod 505 is threaded through the bottom of the slider 506. A fixing block 502 is fixedly connected to the bottom of the main pipe 102. A sliding groove 503 is opened at the bottom of the fixing block 502. The slider 506 is threaded through the inside of the sliding groove 503.
[0037] It should be noted that the fixed bearing 507 is an existing ball bearing, used to connect the bidirectional screw 504 and the second mounting bracket 3. The fixed bearing 507 connects the two, fixing the position of the bidirectional screw 504 without affecting its rotation. The threads on the bidirectional screw 504 are symmetrically arranged from the middle. The two sliders 506 are threaded onto the threads on both sides. The two ends of the limiting rod 505 are fixedly connected to the first mounting bracket 2 and the second mounting bracket 3, respectively. The limiting rod 505 is designed parallel to the bidirectional screw 504, and both rods are inserted into the sliders 506, restricting the sliders 506 from rotating. When the position of the pressing block 4 needs to be moved, the torsion cap 501 drives the bidirectional screw 504 to rotate, and the rotating bidirectional screw 504 drives the slider 506, which is threaded to it and cannot rotate, to move. As the slider 506 moves, the pressing block 4 moves.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
