Problems solved by technology

In this way, the support flange has the following problems: it must bear the stress caused by the gravity load of the catalyst and the local stress caused by the uncoordinated deformation, and the joint corner between the upper surface of the support flange and the cylinder is often cracked
[0004] The traditional solution is to ensure the quality of the support flange and its connection with the cylinder during manufacturing, to maintain smooth operation during reactor operation to reduce stress, to regularly inspect the cylinder of the support flange section during maintenance, and to arrange to stop the device for repair if cracks are found , seriously affecting production safety and economic benefits
[0005] However, traditional solutions cannot meet the requirements of weight load, internal pressure, high temperature and fatigue resistance at the same time

Embodiment 1

[0042] One of the specific implementations of a reactor with an internal support structure of the present application, see figure 1 As shown, its structure includes a cylinder body 1, an upper opening 4 and a lower opening 5 arranged on the cylinder body 1 for feeding in and out of materials, and an inner support structure disposed on the inner wall of the cylinder body 1. In addition, it also includes figure 1 The prior art features in the upper head 2, the lower head 3, the support 6, the inner support structure specifically includes the lower support structure 7, the middle support structure 8 and the upper support structure 9, the above technical features and the reaction in the prior art The structure of the reactor is basically the same, and the reactor with the inner support structure of the present application also has other basic structures of the reactor in the prior art.

[0043] The improvement of the application is: see Figure 2 to Figure 7 ,as well as Figure ...

Embodiment 2

[0048] The second specific embodiment of a reactor with an internal support structure of the present application, the main technical scheme of this embodiment is the same as that of embodiment 1, and the features not explained in this embodiment adopt the explanation in embodiment 1, No further details will be given here. refer to Figure 3 to Figure 7 ,and Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the flange surface of the support flange is set as a streamlined annular smooth surface, and the support flange passes through the streamlined annular smooth surface. Fitted with the support frame for supporting the support frame. Compared with the planar support flange, the support flange with a streamlined annular smooth surface has one of its significant advantages in that it avoids the right-angled corner with the cylinder and reduces local stress. The second significant advantage is that It reduces the height of the flange by increas...

Embodiment 3

[0050] The third specific embodiment of a reactor with an internal support structure of the present application, the main technical scheme of this embodiment is the same as that of embodiment 2, and the features not explained in this embodiment adopt the explanation in embodiment 2, No further details will be given here. refer to Figure 3 to Figure 7 As shown, the difference between this embodiment and embodiment 2 is that the cross-sectional shape is streamlined, the annular smooth surface is an annular conical surface, or an annular double-cone surface formed by connecting two annular conical surfaces. That is, in Figure 3 to Figure 7 The outline of the bearing surface B of the flange on the section is straight, but there is an angle between it and the axis of the reactor. Compared with the flat support flange, one of the significant advantages of the support flange with a tapered surface is that it avoids the right-angled corner with the cylinder and reduces the local s...

Abstract

The invention provides a reactor with an inner supporting structure. The reactor comprises a barrel, material entering and exiting openings arranged on the barrel and the inner supporting structure arranged on the inner wall of the barrel, wherein the inner supporting structure comprises a supporting flange and a supporting rack and the flange surface of the supporting fits the supporting rack and is used for supporting the supporting rack. According to the invention, supporting is realized in the manner that the supporting flange fits the supporting rack through the flange surface of the supporting flange; compared with direct welding of a supporting plate and the inner wall of a barrel of a traditional supporting structure, such a manner has the advantages that strength difference between the supporting flange and the barrel is reduced, local stress concentration between the supporting flange and the inner wall of the reactor is lowered and the supporting flange can bear internal pressure, high temperature and gravitational load at one time, is easy to weld and has low cost; and through usage of the improved inner supporting structure, the reactor can resist corrosion and fatigue and does not crack in operation of the reactor, and has longer service life.

Description

technical field [0001] This application relates to the technical field of various high-temperature and high-pressure reactors used in petroleum refining and chemical industry, coal chemical industry, chemical fertilizer industry, and other various chemical equipment, especially to the field of hydrogenation reactor or desulfurization reactor that reacts through catalysts A reactor with an internal support structure.
