ング1と胴2とで形成される隙間部に収容されている。In these figures, a tube group 6 attached to a plurality of tube sheets 2a and arranged in the axial direction of the cylinder 2 is provided in a cylindrical vertical body 2 of a multi-tube heat exchanger. Heat is exchanged between the tube-side fluid flowing inside the tube group 6 and the body-side fluid flowing outside the tube group 6. An expansion joint 3 is provided between the tube sheets 2a, 2a of the body 2 over the entire periphery thereof which is orthogonal to the axial direction of the body 2, and absorbs a difference in thermal expansion between the body side and the tube side. I have. Reference numeral 1 denotes a case in which the body-side fluid 4 flowing into the expansion joint 3 passes through the perforated plate dispersion sleeve 5 and flows outside each tube of the tube group 6, and leaks from the gap at the end of the dispersion sleeve 5. It is a seal ring that suppresses this. The seal ring 1 is attached to the body 2 by welding, and one end (upper end) of the dispersion sleeve 5 is accommodated in a gap formed by the seal ring 1 and the body 2.

採用されている。The end (lower end) of the dispersion sleeve 5 opposite to the seal ring 1 is attached to the cylinder 2 by welding, and there is no leakage of the cylinder-side fluid at this portion. The end of the dispersion sleeve 5 on the side of the seal ring 1 is not fixed to the body 2 and the seal ring 1 so as not to restrict the movement of the body 2, that is, the expansion and contraction in the axial direction due to the thermal expansion difference between the body side and the tube side. Structure (FIG. 6), or a structure supported by the seal ring 1 with bolts 8 inserted into the elongated holes so as to be slidable in the axial direction of the body 2 (FIG. 8), and formed by the body 2 and the seal ring 1. Is accommodated in the gap. Therefore, in order to minimize the gap from the viewpoint of preventing fluid leakage, a special manufacturing method such as mounting the seal ring 1 in actual condition is adopted.

I do. The liquid leaked from this gap flows along the circumferential direction to the outlet provided on the opposite side of the expansion joint 3.

In this case, there is a problem that it is against the prevention of leakage of the body side fluid. On the other hand, as shown in FIG. 8, when the dispersion sleeve is attached to the seal ring with bolts, the leakage of the body side fluid can be prevented to some extent, but the expansion joint moves within a limited range due to the elongated holes and the bolts. However, there is a problem that the movement of the expansion joint beyond this range is restricted.

動きを拘束することがない。When the expansion joint is provided with an inlet nozzle in the present invention, the body-side fluid flowing into the expansion joint through the inlet nozzle serves as the body, the dispersion sleeve and the dispersion sleeve at the other end of the dispersion sleeve. Attempts to leak through the gap between the dispersing sleeve and the seal ring, but the gap is equipped with a flexible sealing device, which prevents the flow of fluid and prevents leaks. Does not flow to the outlet side along the circumferential direction, and the heat transfer performance of the tube group is not reduced. Further, the flexible sealing device can maintain the sealing property in accordance with the change of the gap due to the movement due to the thermal expansion or the like of the expansion joint, and does not restrict the movement of the expansion joint.

することができる。In this embodiment constructed as described above, as shown by arrows in FIGS. 1 and 2, the body-side fluid 4 entering from the nozzle 9 at the inlet passes through the dispersion sleeve 5. It reaches the outlet nozzle 10 via the tube group 6 and the dispersion sleeve 5 on the outlet side. At this time, the baffle plate 7 prevents the fluid from leaking from the gap between the body 2 and the upper end of the dispersion sleeve 5. Thereby, the flow that flows sideways through the tube group 6 and reaches the dispersion sleeve 5 on the outlet side can be significantly reduced, and the heat transfer performance of the tube group 6 can be improved.

In this embodiment, only one end of the baffle plate 7 'is attached to the upper end of the dispersing sleeve 5, and this is brought into close contact with the inside of the body 2 and the seal ring 1.
The same operation and effect as those of the embodiment can be obtained.

However, the dispersion sleeve is provided inside the nozzle 10 at the exit of the expansion joint, and is fixed to the body. It is also possible to provide a baffle similar to that described above at its end on the other side. In this case, the body side fluid is prevented from leaking from the gap at the end of the dispersion sleeve at the outlet side, and the body side fluid is largely prevented from flowing sideways through the tube group 6 as described above. The heat transfer performance of the group can be improved.
