ている。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view of a swing-type heat exchanger fitting for a heat exchanger according to an embodiment of the present invention. In the figure, the suspension type heat exchanger for hanging type heat exchangers according to the present embodiment is for hanging type heat exchangers used in soda recovery boilers and the like in paper manufacturing plants, and suspension types used in soda recovery boilers and the like. The heat exchanger is formed into a panel shape by welding rod spacers 2 to a plurality of pipes 1, and in a part of the U-bend portion under the pipes 1 like the conventional swing-type metal fittings for hanging heat exchangers. If the supporting hardware is attached and the hanging heat exchangers are connected to each other to prevent vibration, when the suit blower is operated to drop the ash adhering to the hanging heat exchanger, the hanging heat exchange will be performed. Since the vessel swings and twists, excessive stress may locally act on the welded portion of the rod spacer 2 above the anti-slip hardware, causing cracks due to fatigue. One of the U-bend parts under the tube 1 of the heat exchanger Waste Me from attaching the support hardware, the local stress in the weld rod spacer 2 is attached over substantially the entire substantially U-bend portion of the support fittings 3 of the strip-shaped so that not act on.

結することにより振止めを行っている。That is, as shown in the figure, the U-bend of the lower portion of the tube 1 of the suspension heat exchanger in which the rod spacers 2 are welded to form a panel is shown in the swing-off metal fitting for the main suspension heat exchanger. A band-plate-shaped support metal 3 is attached to the portion by bolts 4 through the elongated hole 7 of the support metal 3 over substantially the entire area of the U bend using the gap 8 in the U bend. Then, a plate-shaped support metal 3 is provided below the support metal 3.
It is attached by welding a. Furthermore, another support metal 3b
Is welded to the connecting rod 5, and the supporting metal 3b is connected to the supporting metal 3a.
It is attached by means of bolts 4 and the hanging type heat exchangers are connected to each other to prevent vibration.

換器が整管される効果もある。As described above, in the present anti-slip hardware, the strip-shaped support metal 3 is attached by bolts 4 over substantially the entire U-bend portion under the tube 1 of the suspension heat exchanger, and the support metal 3 is attached to the support metal 3. The hanging type heat exchangers are connected to each other by welding the connecting rods 5 via 3a and 3b. As a result, the hanging type heat exchangers are not twisted even if shaken, so that the welding parts of the rod spacers 2 are locally Excessive stress does not act and cracks due to fatigue do not occur. Further, since the adjacent hanging heat exchangers are connected to each other through the connecting rod 5, there is also an effect that the hanging heat exchangers are aligned.
