Description

Technical Field

[0002] At present, there are various heat exchangers. For example, the publication number is CN218178841U, and the name is a high-temperature solid heat exchanger, which discloses that "by arranging an upper connecting pipe and a lower connecting pipe, the water inlet and outlet of the inner upper horizontal pipe and the inner lower horizontal pipe are ensured to be smooth, thereby greatly improving the water flow circulation speed and ensuring the heat exchange efficiency. It solves the technical problem that the expansion amounts of the upper header and the inner upper horizontal pipe are inconsistent, resulting in welding at the connection position between the upper header and the inner upper horizontal pipe". The upper header, the first heat exchange pipes and the lower header enclose a converging type blanking channel. Since high-temperature solid materials are input into the blanking channel, the high-temperature solid materials enter the converging type blanking channel enclosed by the upper header, the first heat exchange pipes and the lower header. The first heat exchange pipes include multiple ones, and there are gaps between adjacent first heat exchange pipes, so the heat of the high-temperature solid materials entering the blanking channel cannot be fully utilized, the heat exchange efficiency of the heat exchanger is low, a large amount of resources are wasted, and part of the dust and high-temperature solid materials are likely to break away from the blanking channel through the gaps between the first heat exchange pipes, not only polluting the environment, but also the high-temperature solid materials being likely to cause fires or injure the staff.

[0020] As Figures 1-5 shown, a solid heat exchanger includes an upper header 1, a lower header 2, and a plurality of first heat exchange tubes 3. The upper header 1 is surrounded by a feed port 11, the lower header 2 is surrounded by a discharge port 21. One end of each of the plurality of first heat exchange tubes 3 is connected to the upper header 1 and surrounds the feed port 11, and the other end of each of the plurality of first heat exchange tubes 3 is connected to the lower header 2 and surrounds the discharge port 21. A guard plate 4 is connected between adjacent first heat exchange tubes 3. One end of the guard plate 4 is fixedly arranged on the upper header 1, and the other end of the guard plate 4 is fixedly arranged on the lower header 2; the outer diameter of the first heat exchange tube 3 is D, the thickness of the guard plate 4 is h, and the distance from the center line in the thickness direction of the guard plate 4 to the center of the first heat exchange tube 3 is L. The guard plate 4 is between the first heat exchange tubes 3, preventing heat from being lost through the gaps between adjacent first heat exchange tubes 3, resulting in low energy utilization rate, saving energy and avoiding waste of resources; the guard plate 4 blocks the gaps between the first heat exchange tubes 3, preventing high-temperature dust and waste residues from leaking out of the first heat exchange tubes 3 when high-temperature solid materials pass through, polluting the environment or causing a fire to harm the staff; since the guard plate 4 needs to be fixed on the first heat exchange tubes 3, in order to better fix the guard plate 4, the distance from the center line in the thickness direction of the guard plate 4 to the center of the first heat exchange tube 3 is L. Figure 3 is when L = 0, Figure 4 is when at this time, since the first heat exchange tube 3 is cylindrical, there is a distance on both sides of the center of the first heat exchange tube 3 to the center line in the thickness direction of the guard plate 4 that satisfies

[0021]

[0022] The main functions of the protective plate 4 are as follows: first, to enhance heat transfer; second, to enhance the overall structural strength; third, to seal the solid heat exchanger to prevent high-temperature materials from contacting air and causing ablation or explosion due to the volatile components remaining in the materials.

[0023] If the protective plate 4 is to be better installed in two adjacent first heat exchange tubes 3, it needs to be embedded inside. To ensure the stability of the installation, the connection position between the first heat exchange tube 3 and the protective plate 4 is particularly important. According to actual production, it is found that when the embedding between the first heat pipe 3 and the protective plate 4 is small, the temperature difference between the protective plate 4 and the first heat exchange tube 3 is large, and the expansion coefficients between the protective plate 4 and the first heat exchange tube 3 are different. During use, it is easy to cause accidents such as weld cracking. After repeated tests, a preferred implementation method is obtained. When this is the case, it can ensure that heat will not be lost from the gaps between the protective plates 4, and at the same time, it can avoid accidents such as weld cracking caused by different expansion coefficients between the first heat pipe 3 and the protective plate during use.

[0024] The first heat exchange tube 3 and the protective plate 4 are welded or integrally formed; the protective plate 4 and the upper header 1 are welded or integrally formed; the protective plate 4 and the lower header 2 are welded or integrally formed.

[0026] It further includes a lower end cover 6 and a lifting plate 62. The lower end cover 6 is provided with a lower port 61, and the lower port 61 is cooperatively arranged with the discharge port 21.
