[0002] The multi-layer coil structure of reactor heat exchange tubes is a device used for heat transfer in reactors. Compared with single-layer coil structures, multi-layer coil structures usually have higher heat transfer efficiency and more uniform temperature distribution. This structural design includes multiple coils stacked together, which transfer heat from the inside of the reactor to the outside or from the outside to the inside of the reactor in different ways.

[0003] In the prior art, for example, Chinese patent announcement number: CN213455089U discloses "a multi-layer coil structure of a reactor heat exchange tube", including a positioning plate, an inner coil, an intermediate coil, an outer coil, an upper drainage pipe and a lower drainage pipe, wherein the inner coil, the intermediate coil and the outer coil are all coaxial spring-type spiral tube structures, the inner coil, the intermediate coil and the outer coil have the same height, and the coiling diameters increase successively, the inner coil, the intermediate coil and the outer coil are coaxially arranged to form a three-layer coil combination, and the three-layer coil combination passes through three positioning plates in sequence.

[0004] However, in the prior art, during use, the multi-layer coil structure is easily collided, causing the distance between the coils to become smaller due to extrusion, resulting in poor uniformity of the multi-layer coil structure during heat exchange, resulting in uneven temperature distribution inside the reactor. Summary of the invention

[0024] Specifically, when the No. 2 coil body 18 is squeezed and impacted from the inside, the connecting outer tube 24 on one side slides along the connecting inner tube 25. At this time, the No. 3 spring 29 inside the connecting outer tube 24 is compressed, and the No. 3 spring 29 on the other side is stretched.
