Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a vibration-resistant heat exchanger. Background Technology

[0002] Heat exchange equipment is a device that facilitates heat exchange between materials at different temperatures. It is used for heating, reboiling, evaporation, cooling, and condensation of materials. Its function is to change or maintain the temperature or phase of materials to meet the different requirements of various process operations. It can also recover waste heat and improve energy utilization, thereby saving energy and increasing efficiency. Among heat exchanger structures, the single-arch structure of the baffle plate is the simplest to manufacture and assemble, and is the most widely used. It can increase the turbulence of the shell-side medium and improve the shell-side heat transfer coefficient.

[0003] With the increasing scale and intensification of chemical plants, many heat exchangers adopt large-diameter and long heat exchange tubes and reduce the baffle spacing. In order to increase the flow velocity in the tube side of the heat exchanger, improve heat transfer efficiency and reduce the risk of scaling, a multi-tube structure is adopted, which leads to vibration during the operation of the heat exchanger.

[0004] Because heat exchange tubes need to pass through baffles and are supported by baffles, it is difficult for heat exchange tubes to pass through smoothly in the case of multiple baffles. In order to ensure that the heat exchange tubes can pass through smoothly, the size of the tube holes on the baffles is enlarged. Vibration during operation causes the heat exchange tubes to sway, and shearing action occurs between them and the baffles, which can cause the heat exchange tubes to break and leak, resulting in failure. In severe cases, it can lead to the scrapping of the equipment and affect the heat transfer efficiency and service life of the heat exchanger.

[0005] This phenomenon has appeared in many existing devices, which has attracted the attention and concern of the industry. Our company has independently developed and manufactured an anti-vibration heat exchanger that effectively reduces the vibration impact of the heat exchanger and extends its service life. Utility Model Content

[0006] This utility model discloses an anti-vibration heat exchanger, which solves the problem that the shearing action between the heat exchange tube and the baffle plate causes the heat exchange tube to break, resulting in leakage and failure, and in severe cases, equipment scrapping, affecting the heat transfer efficiency and service life of the heat exchanger.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A vibration-damping heat exchanger includes a heat exchanger body, a baffle plate fixed inside the heat exchange chamber of the heat exchanger body, a heat exchange tube passing through the baffle plate, and an anti-vibration component on the baffle plate. The anti-vibration component includes a set of first connecting rods and a set of second connecting rods fixed on both sides of the baffle plate. The first connecting rods are distributed from front to back and are vertically arranged. The first connecting rods have a set of first protrusions. The heat exchange tubes are located between two adjacent first connecting rods and are in contact with the first protrusions. The second connecting rods are distributed from top to bottom and are horizontally arranged. The second connecting rods have a set of second protrusions. The heat exchange tubes are located between two adjacent second connecting rods and are in contact with the second protrusions.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] After a set of No. 1 connecting rods and a set of No. 2 connecting rods are fixed on both sides of the baffle plate, the No. 1 protrusions on the two adjacent No. 1 connecting rods can respectively abut against the two sides of the heat exchange tube, and the No. 2 protrusions on the two adjacent No. 2 connecting rods can respectively abut against the top and bottom of the heat exchange tube, thus limiting the heat exchange tube in four directions and preventing the heat exchange tube from shearing against the baffle plate. This utility model can effectively limit and fix the heat exchange tube, prevent the heat exchange tube from being sheared against the baffle plate and thus prevent damage to the heat exchange tube, ensuring the heat transfer efficiency and service life of the heat exchanger.

The heat exchange tube 3 is located between two adjacent second connecting rods 5 and is in contact with the second protrusions 51.

[0019] First embodiment: After fixing a set of first connecting rods 4 and a set of second connecting rods 5 to both sides of the baffle plate 2, the heat exchange tube 3 is located between two adjacent first connecting rods 4 and in contact with the first protrusion 41. At the same time, the heat exchange tube 3 is also located between two adjacent second connecting rods 5 and in contact with the second protrusion 51. This can limit the movement of the heat exchange tube 3 around its perimeter, thus defining the top, bottom, front, and back surfaces of the heat exchange tube 3. Figure 1 (as shown in the diagram) is pressed against the heat exchange tube 3 to fix it, thus preventing the heat exchange tube 3 from shearing against the baffle plate 2; both the first protrusion 41 and the second protrusion are elliptical in shape.

[0020] like Figure 4 and Figure 5As shown, the vibration-damping assembly includes a set of first fixing rods 6 and a set of second fixing rods 7, each fixed to one side of the baffle plate 2. The first fixing rods 6 are distributed from front to back and are vertically arranged. A set of first vibration-damping blocks 61 are provided on the first fixing rods 6. The heat exchange tube 3 is located between two adjacent first fixing rods 6 and is in contact with the first vibration-damping blocks 61. The second fixing rods 7 are distributed from top to bottom and are horizontally arranged. A set of second vibration-damping blocks 71 are provided on the second fixing rods 7. The heat exchange tube 3 is located between two adjacent second fixing rods 7 and is in contact with the second vibration-damping blocks 71. The second fixing rods 7 are provided with a bent portion for the first fixing rods 6 to be inserted into.

[0021] Second embodiment: After fixing the first fixing rod 6 to one side of the baffle plate 2, the second fixing rod 7 is then fixed to the baffle plate 2, so that the overlapping part of the first fixing rod 6 and the second fixing rod 7 is inserted into the bent part of the second fixing rod 7, which can further increase the firmness of the first fixing rod 6; the first anti-vibration block 61 on the two adjacent first fixing rods 6 is in contact with the two sides of the heat exchange tube 3 respectively, and the second anti-vibration block 71 on the two adjacent second fixing rods 7 is in contact with the top and bottom surfaces of the heat exchange tube 3 respectively, thus completing the limitation of the heat exchange tube 3 in four directions and preventing the heat exchange tube 3 from shearing with the baffle plate 2; the first anti-vibration block 61 and the second anti-vibration block 71 are respectively arranged in an elliptical shape.

[0022] like Figure 4 As shown, a rod 62 is fixed to the first anti-vibration block 61, and a hole for inserting the rod 62 is provided on the baffle plate 2. A screw 72 is threaded onto the bent part of the second fixing rod 7, and screw holes corresponding to the screw 72 are provided on both the first fixing rod 6 and the baffle plate 2. The rod 62 can be inserted into the hole on the baffle plate 2 to place the first fixing rod 6, or the rod 62 can be welded to the baffle plate 2 to directly fix the first fixing rod 6 and the baffle plate 2 together. Then, the second fixing rod 7 is attached to the baffle plate 2, and the screw 72 is used to fix the second fixing rod 7 and the first fixing rod 6 to the baffle plate 2 respectively to complete the fixation of the second fixing rod 7. The tail of the screw 72 can also be welded to the baffle plate 2 after passing through it.

The baffle plate 2 is threadedly connected to the first bolt 42 and the second bolt 52, respectively. The first protrusion 41 and the second protrusion 51 can be fixed to both sides of the baffle plate 2 by the first bolt 42 and the second bolt 52, respectively, so that the first connecting rod 4 and the second connecting rod 5 are fixed on the baffle plate 2; the first bolt 42 and the second bolt 52 can also be welded to the baffle plate 2.

[0024] like Figure 2 As shown, a reinforcing rod 53 is fixed to the second connecting rod 5, penetrating the baffle plate 2. A through hole is provided on the first connecting rod 4 for the reinforcing rod 53 to pass through. A nut 54, which contacts the first connecting rod 4, is threaded onto the reinforcing rod 53. After the first connecting rod 4 and the second connecting rod 5 are fixed to both sides of the baffle plate 2, the reinforcing rod 53 passes through the through hole on the first connecting rod 4, and then the nut 54 can be threaded onto the reinforcing rod 53, further increasing the firmness of the first connecting rod 4 and the second connecting rod 5 fixed to the baffle plate 2. The nut 54 can also be directly welded to the reinforcing rod 53.
