[0002] Graphite heat exchangers are heat exchangers whose heat transfer components are made of graphite. The graphite used to manufacture heat exchangers should be impermeable; commonly used types include impregnated impermeable graphite and molded impermeable graphite.

[0013] Figure 2 yes Figure 1 A schematic diagram of the structure of region A in the diagram;

[0014] Figure 3 yes Figure 1 A structural diagram of region B in the diagram. Detailed Implementation

[0015] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0016] like Figure 1-3 This application provides a heat exchanger head cooling device, including a heat exchange cylinder 1, a head 2, and a cooling assembly 3. The heat exchange cylinder 1 has a head 2 at its end, with a vent 21 inside. A cover plate 4 for pressing the head 2 is provided outside the vent 21, and the cooling assembly 3 is fitted onto it. The heat exchange cylinder 1 has a heat exchange block 5 inside, a heat exchange circulation water inlet 11 on its upper side, and a circulation water pipe 12 connecting the heat exchange block 5 and the heat exchange circulation water inlet 11 inside the side wall of the heat exchange cylinder 1. The head 2 has multiple sets of U-shaped water pipes 22 connected to the circulation water pipes 12. In the above design, the head 2 has U-shaped water pipes 22 to introduce cooling circulation water, cooling the entire head 2. Simultaneously, the vent 21 of the head 2 is the first to contact the high-temperature gas, while the cooling assembly 3 can be individually connected to cooling water to directly cool the vent 21.

[0017] The cooling assembly 3 includes an annular groove 31, which is located on the side of the cover plate 4 away from the heat exchange block 5 and is fitted onto the outside of the vent 21. A cooling water inlet 32 ​​and a cooling water outlet 33 are located on the upper side of the annular groove 31. In the above design, the annular groove 31 surrounds the outer wall of the vent 21. When cooling water flows into the annular groove 31 from the cooling water inlet 32, it cools the vent 21 before flowing out through the cooling water outlet 33.

[0018] An annular connecting plate 34 is provided on the outer side of the annular groove 31. The annular connecting plate 34 has a first connecting hole 35, which is connected to the cover plate 4 by a first bolt 36. The annular connecting plate 34 in the above design can ensure a tight connection between the annular groove 31 and the cover plate 4.

[0019] A collar 6 is provided at the end of the vent 21, and a second connecting hole 61 is provided in the collar 6. The second connecting hole 61 is connected to the annular groove 31 by a second bolt 62. The collar 6 in the above design can ensure the stability of the annular groove 31 and prevent the annular groove 31 from detaching from the vent 21.

[0020] The heat exchange cylinder 1 is provided with lifting lugs 7 on the top for lifting the heat exchange cylinder 1.

[0021] The cover plate 4 has a third connecting hole 41 on its edge, and the heat exchange cylinder 1 has a side plate 13 at its end. The side plate 13 has a fourth connecting hole 14 corresponding to the third connecting hole 41. The third connecting hole 41 and the fourth connecting hole 14 are connected by a third bolt 15. The third bolt 15 in the above design can stably connect the cover plate 4 and the heat exchange cylinder 1.

[0022] In its specific operation, high-temperature gas enters the heat exchange cylinder 1 through the vent 21. Due to the high temperature of the gas, the temperature of the vent 21, which initially contacts the gas, rises accordingly. The cooling water inlet 32 ​​of the annular groove 31 is then opened, allowing the cooling water in the annular groove 31 to cool the vent 21. Simultaneously, since the U-shaped water pipe 22 in the end cap 2 connects to the circulating water pipe 12 of the heat exchange block 5, the circulating cooling water flowing through the U-shaped water pipe 22 effectively cools the end cap 2, preventing it from aging due to high temperatures.

[0023] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
