[0025] It is not difficult to find from the above content that when the internal component, i.e., the center cap, is used, it is connected to the cap body 1 by using the mounting portion 21 of the suspension beam 2 at the top, and the lap portion 22 at the other end of the suspension beam 2 is lap-supported on the internal support of the continuous reforming reactor, so that the suspension beam can slide freely when subjected to thermal expansion to prevent deformation after thermal expansion. Specifically, in the design of the suspension beam 2, the mounting portion 21 of the suspension beam 2 can be connected to the cap body 1 by welding. The lap portion 22 at the other end of the suspension beam 2 extends out of the outer side of the maximum outer diameter edge of the cap body 1, so that the lap portion 22 leaves the top side of the cap body 1 and extends to the supporting and hanging position inside the continuous reforming reactor, so as to realize the hoisting and installation of the cap body 1. The problem that the cap body 1 vibrates due to the flow of process logistics, causing the center cap to be in a large position, and finally causing serious damage, is solved.

[0026] Specifically, the material of the hanging beam 2 can be selected from 304, 316 or 321 stainless steel materials. That is, the hanging beam 2 of the utility model can be formed by cutting and forming the steel plates of the above materials.

The first welding leg 232 can be connected to the upper surface of the cap body 1 by welding. The first lap leg 233 is supported on the internal support of the continuous reforming reactor by lap connection.

[0040] Similarly, the second suspension beam 24 includes: a second suspension beam plate 243, which is arranged parallel to the upper surface of the cap body 1, and the second suspension beam plate 243 and the first suspension beam plate 231 are perpendicular to each other; a second welding leg 244, the top end of the second welding leg 244 is connected to one end of the bottom of the second suspension beam plate 243, and the lower end of the second welding leg 244 is connected to the upper surface of the cap body 1 to form a mounting portion 21; and a second lap leg 245, the top end of the second lap leg 245 is connected to the two ends of the bottom of the second suspension beam plate 243 to form a lap portion 22; wherein the second suspension beam plate 243, the second welding leg 244 and the second lap leg 245 are an integrally formed structure.

[0043] In one embodiment of the utility model, in a continuous reforming reactor, the inner wall of the reactor shell 3 is axially arranged with several support rings 4, and the gaps between the support rings 4 are filled by using sealing plates 5, so as to form an annular cylindrical structure 6.
