One end of the support column 31 is connected to the shell 1, and the other end is arranged toward the heat exchange component 2. The buffer spring 32 is arranged between the support column 31 and the heat exchange component 2. When the medium that needs heat exchange enters the shell 1, the heat exchange medium contacts the medium that needs heat exchange through the heat exchange component 2. During the contact process, the heat exchange component 2 eliminates the thermal stress in the heat exchange process through the buffer spring 32.
[0038] This embodiment takes the heat exchange of low-temperature nitrogen as an example.
[0039] The nitrogen enters the shell 1 for heat exchange, causing the temperature of the nitrogen to rise. After the steam enters the heat exchange component 2, it contacts the low-temperature nitrogen in the shell 1. During the contact process, the heat on the heat exchange component 2 exchanges heat with the low-temperature egg beater, causing the temperature of the nitrogen to rise. During the heat exchange process, the heat exchange component 2 will be deformed to a certain extent due to the temperature difference. In order to prevent the deformation from affecting the normal operation of the heat exchange component 2, a buffer spring 32 is provided between the heat exchange component 2 and the support column 31. The buffer spring 32 provides space for the heat exchange component 2 after it is deformed by heat, avoiding extrusion damage to the heat exchange component 2 and improving the operating stability of the entire steam heater.

[0041] In order to facilitate the replacement of the buffer spring 32, the buffer spring 32 is placed in the limit barrel 34, and the limit is fixed to the mounting plate 33 by bolts. When the buffer spring 32 needs to be replaced or overhauled, the bolts are loosened, and the limit barrel 34 and the buffer spring 32 installed in the limit barrel 34 are taken out from between the support column 31 and the heat exchange component 2. After the overhaul is completed or the buffer spring 32 is replaced, it can be installed in place.

[0045] In one embodiment, if Figure 1As shown, during the heat exchange process, the steam in the heat exchange component 2 is condensed to form condensed water.

[0046] In one embodiment, if Figure 1 As shown, in order to facilitate the maintenance or replacement of the buffer assembly 3, after the heat exchange assembly 2 is installed, the interior of the shell 1 is divided into a heat exchange area 12 and an installation and maintenance area 13, and the shell 1 is provided with an inspection door 14 corresponding to the installation and maintenance area 13.
[0047] In one embodiment, if Figure 1 As shown, in order to conveniently send nitrogen into or out of the shell 1, a nitrogen inlet 15 and a nitrogen outlet 16 are respectively provided on opposite side walls of the shell 1.
[0048] In order to prevent people from lacking oxygen when entering the maintenance area during maintenance, a nitrogen release port 17 is provided at the top of the shell 1 , and a nitrogen blow-off port 18 is provided at the bottom of the shell 1 .
[0049] In one embodiment, if Figure 1 and Figure 3 As shown, in order to make full use of the space and achieve efficient heat transfer, the nitrogen inlet and outlet in the shell adopt a round-square structure to ensure the heat transfer contact area between the nitrogen and the heat exchange component 2 (steam fin tube).
