Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a flexible support structure for the outlet pipe system of a steam reformer. Background Technology

[0002] As a core piece of equipment, the steam reformer's outlet piping system plays a crucial role in conveying high-temperature, high-pressure syngas. However, the existing support structure of the steam reformer's outlet piping system faces significant technical bottlenecks under high-temperature conditions, making it difficult to meet the demands of modern industry for equipment reliability, safety, and long-term operation.

[0003] Traditional support structures mostly employ rigid connections secured by welding or bolts, which cannot adapt to the high-temperature thermal expansion of the outlet piping system (the operating temperature of the piping system typically reaches 800-1000℃, and the thermal expansion can reach tens of millimeters). When the piping system displaces due to thermal expansion, the rigid support forms a fixed constraint point, resulting in enormous thermal stress inside the pipe. Secondly, existing flexible supports (such as simple spring supports) can only achieve displacement compensation in one direction and cannot cope with the complex three-dimensional thermal expansion of the piping system.

[0004] Therefore, it is necessary to provide a flexible support structure for the outlet piping system of a steam reformer to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the aforementioned problems, this application provides a flexible support structure for the outlet piping system of a steam reformer, thereby solving the issues raised in the background art regarding the inability to unload thermal stress and cope with the complex three-dimensional thermal expansion of the piping system.

[0006] To achieve the objectives of this application, the following technical solution is provided:

[0007] This application provides a flexible support structure for the outlet pipe system of a steam reformer, including: a bracket with a base fixedly installed at its upper end, and a cover fixedly installed on the base;

[0008] The side limiting components are configured to be at least 2n (n≥2) units, and n evenly distributed side limiting components are symmetrically arranged on the left and right sides of the housing; and

[0009] The top limiting assembly is configured to be at least 2 (n-1) units, each of which is installed on the top of the inner side of the housing located between each pair of the side limiting assemblies.

[0010] In one possible implementation, a pad is fixedly installed at the bottom of each bracket, and the pad is fixed to the ground.

[0011] In one possible implementation, the side limiting component includes:

[0012] The first base has a first H-shaped handle rotatably provided on one side and a second H-shaped handle rotatably provided on the other side.

[0013] A first shock absorber, one end of which is rotatably mounted on the first base, and the other end of which is rotatably mounted on the first H-shaped handle, wherein a first wheel is rotatably mounted on the end of the first H-shaped handle away from the first base; and

[0014] The second shock absorber has one end rotatably mounted on the first base and the other end rotatably mounted on the second H-shaped handle. The end of the second H-shaped handle away from the first base has a second wheel body rotatably mounted on it.

[0015] In one possible implementation, the first base is fixedly disposed on both sides inside the housing.

[0016] In one possible implementation, the top limiting assembly includes: a second base, on which a third H-shaped handle is rotatably disposed, and on which a third shock absorber is rotatably disposed, the end of the third shock absorber away from the second base being rotatably disposed on the third H-shaped handle, and on which a third wheel is rotatably disposed at the end of the third H-shaped handle away from the second base.

[0017] In one possible implementation, the second base is fixedly disposed on the top of the inner side of the housing.

[0018] In one possible implementation, the first wheel, the second wheel, and the third wheel are all high-temperature resistant rubber wheels with an outer layer of rock wool insulation and an inner layer reinforced with metal wire.

[0019] The beneficial effects of this utility model are:

[0020] This invention places the outlet pipe between the side limiting assembly and the top limiting assembly. When the pipe undergoes thermal displacement due to temperature changes, the side limiting assembly and the top limiting assembly respond first, allowing the pipe to move freely in three-dimensional space. The first, second, and third shock absorbers provide resistance during displacement, slowing down the displacement speed. The arrangement of the first, second, and third wheel bodies forms a second resistance barrier, preventing impact from sudden pipe displacement. This not only ensures the overall stability of the pipeline system but also avoids stress concentration and structural damage caused by rigid constraints. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this application, unless otherwise stated, "multiple" means three or more.

[0030] Figures 1-5 A flexible support structure for a steam reformer outlet piping system provided in this application embodiment includes:

[0031] A bracket 1 has a base 2 fixedly mounted on its upper end, and a cover 3 is fixedly mounted on the base 2;

[0032] The side limiting components 4 are configured in at least 2n (n≥2) units, and n evenly distributed side limiting components 4 are symmetrically arranged on the left and right sides of the housing 3; and

[0033] The top limiting component 5 is configured to be at least 2 (n-1) units, which are respectively installed on the top of the inner side of the cover 3 located between each pair of the side limiting components 4.

[0034] In one possible implementation, a pad 6 is fixedly installed at the bottom of each of the brackets 1, and the pad 6 is fixedly installed to the ground.

[0035] It should be added that, in practical applications, the outlet pipe of a steam converter typically adopts a combined structure of "metal pipe + insulation layer + outer sheath". The inner layer is a heat-resistant alloy steel pipe (responsible for medium transmission); the insulation layer mainly uses aluminum silicate fiber felt, which has a temperature resistance range of 1000–1300℃ and a low thermal conductivity (0.04–0.06W / (m·K)). It directly contacts the high-temperature pipe and effectively blocks heat radiation. Rock wool is used in the medium-temperature zone. Due to its high-temperature resistance (700-800℃) and Class A fire resistance, rock wool is often used as the outer insulation material for steam pipes. It forms a heat insulation layer by wrapping the metal pipe to reduce heat loss and lower the outer wall temperature; the outer layer is a metal sheath or aluminized film (for mechanical protection and corrosion prevention).

[0036] In one possible implementation, the side limiting component 4 includes:

[0037] The first base 41 has a first H-shaped handle 42 rotatably provided on one side and a second H-shaped handle 43 rotatably provided on the other side.

[0038] A first shock absorber 44, one end of which is rotatably mounted on the first base 41, and the other end of which is rotatably mounted on the first H-shaped handle 42, wherein a first wheel 46 is rotatably mounted on the end of the first H-shaped handle 42 away from the first base 41; and

[0039] The second shock absorber 45 has one end rotatably mounted on the first base 41 and the other end rotatably mounted on the second H-shaped handle 43. The second wheel 47 is rotatably mounted on the end of the second H-shaped handle 43 away from the first base 41.

[0040] In one possible implementation, the first base 41 is fixedly disposed on both sides inside the housing 3.

[0041] In one possible implementation, the top limiting assembly 5 includes: a second base 51, on which a third H-shaped handle 52 is rotatably disposed, and on which a third shock absorber 53 is rotatably disposed, the end of the third shock absorber 53 away from the second base 51 being rotatably disposed on the third H-shaped handle 52, and on which a third wheel 54 is rotatably disposed at the end of the third H-shaped handle 52 away from the second base 51.

[0042] In one possible implementation, the second base 51 is fixedly disposed on the top of the inner side of the housing 3.

[0043] In one possible implementation, the first wheel 46, the second wheel 47, and the third wheel 54 are all made of rock wool insulation on the outer layer and metal wire reinforced high-temperature resistant rubber on the inner layer. The rock wool insulation can reduce the external temperature to the rubber's tolerance range, while the metal wire reinforced rubber wheel forms a gradient protection structure. When the pipeline suddenly shifts, the high-temperature resistant rubber wheel can prevent the pipeline from directly impacting the casing 3 and limit the displacement of the pipeline. At the same time, the high-temperature resistant rubber wheel provides elastic cushioning for the pipeline.

[0044] Working principle:

[0045] During installation, the steam converter outlet pipe is directly clamped between the first wheel body 46, the second wheel body 47, and the third wheel body 54. When the outlet pipe undergoes thermal displacement due to temperature changes, the side limiting components 4 and the top limiting component 5 respond first. The pipe first transfers thermal stress to the first wheel body 46, the second wheel body 47, and the third wheel body 54, causing the first H-shaped rotating handle 42, the second H-shaped rotating handle 43, and the third H-shaped rotating handle 52 to deflect. This deflects the pipe through the corresponding first shock absorber 44, the second shock absorber 45, and the third shock absorber 53, providing resistance during the displacement process, slowing down the displacement speed of the pipe, and unloading and buffering the thermal stress. When the pipe suddenly displaces, it presses against the first wheel body 46, the second wheel body 47, or the third wheel body 54. The first wheel body 46, the second wheel body 47, or the third wheel body 54 form a second resistance barrier, preventing the pipe from directly impacting the casing 3 and limiting the pipe, while also providing elastic buffering.

[0046] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. This application is not limited to the exact structures described above and illustrated in the accompanying drawings, and it should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, various changes and modifications made without departing from the concept of this application should be considered to fall within the protection scope of this application.
