Description

Technical Field

[0001] The utility model relates to the technical field of pipeline support and suspension, in particular to a high-temperature pipeline support and suspension bracket based on a low heat dissipation and thermal insulation structure. Background Art

[0002] The design and form selection of pipe supports and hangers are an important part of the design of the piping system. For high-temperature pipelines, such as molten salt pipelines and steam pipelines in solar thermal power plants, due to the high temperature of the medium, thermal bridge effects will occur when traditional supports and hangers are used, resulting in energy loss and even affecting safe operation. For molten salt pipelines, due to the high freezing point, heat dissipation at the supports and hangers may cause local solidification of molten salt, and in severe cases, even pipeline blockage, affecting safe operation. Insulating supports and hangers use the low thermal conductivity of insulating materials to reduce the heat dissipation of pipe supports and hangers. However, since the strength of insulating materials is much lower than that of metal materials, in actual applications, the insulating materials often cannot withstand the load at the pipe supports and hangers and break;

[0003] In the design of conventional pipe supports and hangers, the pipe part of the high-temperature pipe support and hanger is wrapped inside the insulation layer and connected to the root of the support and hanger through a connector. At the point where the support and hanger passes through the insulation layer, it is inevitable that some of the pipe heat will be dissipated to the outside through the support and hanger parts. The size of the parts where the support and hanger passes through the insulation layer directly affects the amount of heat dissipated from the pipe to the outside. Utility Model Content

[0004] In order to solve the problem of heat loss caused by the thermal insulation structure of the existing pipeline support and hanger in the prior art, the utility model provides a high-temperature pipeline support and hanger based on a low heat dissipation thermal insulation structure which reduces heat loss.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A high-temperature pipeline support and hanger based on a low heat dissipation and thermal insulation structure comprises a pipeline and a support and hanger connected to the pipeline, and also comprises an insulation layer, wherein the insulation layer is wrapped around the outside of the connection part between the support and hanger and the pipeline and extends to the root of the support and hanger, so that only a part of the support and hanger is exposed.

[0007] Furthermore, the insulation layer extends toward the axial direction of the pipeline, so that the connection between the support bracket and the pipeline is also wrapped, thereby preventing heat from being lost from the pipeline connection.

[0008] Furthermore, the gaps in the wrapping area of ​​the thermal insulation layer are filled with soft thermal insulation materials, which can reduce the contact area of ​​the parts on both sides of the gap and effectively block the conduction of heat.

[0009] Furthermore, the support and hanger are made of metal material, which reduces heat dissipation without reducing the strength of the support and hanger, thus ensuring safe and reliable operation.

[0010] Beneficial effects: The utility model optimizes the insulation structure at the support and hanger position to minimize the heat dissipation from the pipeline to the environment; reduces the area of ​​the support and hanger components exposed outside the insulation structure to achieve the effect of reducing heat dissipation; while reducing heat dissipation, the strength of the support and hanger is not reduced to ensure safe and reliable operation; only the local insulation structure and the material of a small number of support and hanger components are changed, so the cost is low; it is applicable to a variety of traditional support and hanger structures and has good applicability.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0027] When the pipeline is in operation, the medium temperature inside the pipeline is very high, and the pipe wall in contact with the medium is very close to the working medium temperature. The temperature of the pipe supports and hangers directly welded or in direct contact with the pipeline is also very high. If this part of the supports and hangers is exposed outside the insulation layer, the heat in the pipeline will be dissipated to the external environment through the supports and hangers.

[0028] The utility model aims to design a high-temperature pipe support and hanger based on a low heat dissipation insulation structure. For this purpose, a special insulation structure at the support and hanger is designed, and the materials of the support and hanger components within the insulation range are appropriately adjusted to adapt to high-temperature operating conditions. The main design idea is to add non-metallic insulation material between the support and hanger pipe and the outer wall of the pipeline to isolate the heat in the pipeline from being lost to the support and hanger root and the environment.

[0029] The utility model is specially designed for the insulation structure and materials of the support and hanger components of the pipe, and the support and hanger parts that are welded or in direct contact with the pipe are completely covered inside the insulation structure, and the material grade of the support and hanger parts is appropriately increased to adapt to the temperature under the operating conditions inside the insulation layer. Part of the parts that are not in direct contact with the pipe are inside the insulation structure, and the other part is outside the insulation structure. The gaps at the joints of the supports and hangers should be filled with soft insulation materials to effectively block the conduction of heat. In this way, the contact area of ​​the joints is small and filled with insulation materials, thereby effectively blocking most of the heat transfer between the parts, achieving the effect of reducing heat dissipation.

[0030] The utility model discloses a high-temperature pipe support and hanger based on a low heat dissipation and thermal insulation structure, comprising a pipe 1 and a support and hanger 2 connected to the pipe 1, and also comprising an insulation layer 3, wherein the insulation layer 3 is wrapped around the outside of the connection portion between the support and hanger 2 and the pipe 1, and extends toward the root of the support and hanger 2, so that only a portion of the support and hanger 2 is exposed.

[0031] The heat-insulating layer 3 extends toward the axial direction of the pipeline 1 , so that the connection portion between the support bracket 2 and the pipeline 1 is also wrapped.

[0032] The gaps in the wrapped area of ​​the insulation layer 3 are filled with soft insulation materials. The gaps here include the connection gaps between the parts of the support and hanger 2, and can also be the connection gaps between the pipe 1 and the support and hanger 2. The insulation materials can be selected but not limited to materials such as insulation cotton.

[0033] In order to ensure structural strength, the support brackets may be made of but not limited to metal materials.

[0034] The main structural type of the high-temperature pipe support and hanger based on the low heat dissipation insulation structure is similar to the traditional support and hanger. The vertical pipe support adopts the ear axis limit frame type, the vertical pipe hanger adopts the riser pipe clamp type, and the horizontal pipe hanger adopts the three-hole pipe clamp type.

[0035] The utility model can be applied to horizontal pipelines and vertical pipelines, and the support and hanger forms include limit frames, rigid hangers, spring hangers, etc. Based on conventional pipeline supports and hangers, the utility model optimizes the design of the material and insulation structure of the pipeline at the support and hanger, and achieves the purpose of reducing the heat dissipation by minimizing the heat dissipation area of ​​the pipeline support and hanger to the outside and appropriately increasing the insulation range. The utility model can not only reduce the heat dissipation at the pipeline support and hanger to the greatest extent, but also ensure the strength of the support and hanger, and ensure safe operation.

[0036] Specifically, the following embodiments are included:

[0037] Embodiment 1:

[0038] In this embodiment, the pipeline is a vertical pipeline, and an ear shaft type limit frame is adopted. Specifically, the support bracket 2 includes a bracket 211 and a limit frame 212. The bracket 211 is welded to the pipeline 1. The support bracket 2 also includes a base 213. The limit frame 212 is fixed on the base 213. The insulation layer 3 wraps the entire bracket 211 and extends a distance toward the pipeline 1 and the limit frame 212. There is a gap between the bracket 211 and the adjustment bracket 211. The gap 214 between the bracket 211 and the limit frame 212 can be flexibly adjusted according to the displacement requirements of the bracket 211. The limit frame 212 can be flexibly transformed into an X-axis limit, Y-axis limit and Z-axis limit guide bracket. The gap 214 between the limit frame 212 and the bracket 211 is filled with insulation material.

[0039] Embodiment 2:

[0040] In this embodiment, the pipeline is a vertical pipeline, and the support bracket 2 includes a riser pipe clamp 221 and a hanger 222. The riser pipe clamp 221 is fixed to the pipeline 1, and the hanger 222 is fixed to the riser pipe clamp 221. The insulation layer 3 wraps the entire riser pipe clamp 221 and extends a certain distance toward the pipeline 1 and the hanger 222.

[0041] Embodiment 3:

[0042] In this embodiment, the pipeline is a horizontal pipeline, and the support bracket 2 includes a three-hole pipe clamp 231 and a hanger 232. The three-hole pipe clamp 231 is clamped on the pipeline 1, and the hanger 232 is fixed to the three-hole pipe clamp 231. The insulation layer 3 wraps the connection between the three-hole pipe clamp 231 and the pipeline 1, and extends a certain distance to the pipeline 1 and the hanger 232.

[0043] In view of the heat loss caused by using traditional supports and hangers to support high-temperature pipelines, and the low strength of non-metallic insulation supports and hangers, the utility model proposes a high-temperature pipeline support and hanger structure based on a low heat dissipation and thermal insulation structure. Based on the traditional pipeline support and hanger structure, this support and hanger form reduces the heat transfer area of ​​the pipeline support and hanger to the outside, and combines the thermal insulation design at the support and hanger to achieve the purpose of reducing heat dissipation, and has a simple and practical structure. It can be applied to high-temperature process pipelines such as steam-water pipelines or molten salt pipelines. For different support and hanger types, the thermal insulation range of the pipeline at the pipeline support and hanger can be increased as needed; the material of the internal insulation pipeline support and hanger parts can also be adjusted to adapt to the operating temperature.

[0044] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
