[0025] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0026] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0027] Currently, existing high-temperature devices, such as high-temperature steam units and boilers, use rock wool for insulation of high-temperature pipelines. However, the insulation performance of rock wool is relatively limited, which restricts the heat transfer efficiency of high-temperature pipelines. Furthermore, poor insulation performance can also result from incomplete joint connections during the installation of the insulation layer.

[0028] Based on this, this disclosure provides a high-temperature pipeline, comprising a pipeline body and an insulation layer. The insulation layer is evenly distributed along the circumference of the pipeline body on its outer wall. The insulation layer includes a connecting portion and multiple insulation splicing portions, which are detachably connected via the connecting portion for easy transport and on-site installation. This avoids damage to the insulation layer during transportation or the inconvenience of installing the insulation layer after the pipeline body is installed. Furthermore, the insulation splicing portions of this disclosure are made of nano-ceramic aerogel composite material. Because nano-ceramic aerogel composite material has excellent properties such as low thermal conductivity, high temperature resistance, high water repellency, and lightweight, its thermal conductivity can reach 0.023 W / m·K at operating temperatures below 350℃. In high-temperature pipeline sections of equipment, boilers, etc., it can achieve a cooling effect of more than 10% compared to ordinary rock wool insulation materials. By implementing the technical solution disclosed herein, the surface temperature of the pipeline body can be reduced, thereby improving the insulation performance of high-temperature pipelines, and making them easier to carry and install on-site.

[0029] The following detailed description of the high-temperature pipeline is provided through specific embodiments:

[0030] Reference Figures 1 to 4As shown, a high-temperature pipeline is provided in the first aspect of this disclosure, including a pipeline body 1 and an insulation layer 2. The insulation layer 2 is evenly distributed on the outer wall of the pipeline body 1 along the circumference of the pipeline body 1. The insulation layer 2 includes a connecting part and a plurality of insulation splicing parts 21. The plurality of insulation splicing parts 21 are detachably connected through the connecting part, and the insulation splicing parts 21 are made of nano-ceramic aerogel composite material.

[0031] This disclosure includes a pipeline body 1 and an insulation layer 2. The insulation layer 2 is evenly distributed along the circumference of the pipeline body 1 on the outer wall of the pipeline body 1. The insulation layer 2 includes a connecting part and multiple insulation splicing parts 21. The multiple insulation splicing parts 21 are detachably connected to each other through the connecting part, which facilitates carrying and on-site installation. This avoids damage to the insulation layer during transportation when the pipeline is installed with the insulation layer on, or avoids the inconvenience of installing the insulation layer 2 after the pipeline body 1 is installed. Moreover, the insulation splicing parts 21 of this disclosure are made of nano-ceramic aerogel composite material. Specifically, the nano-ceramic aerogel composite material is an aerogel composite thermal insulation material based on silica aerogel and ceramic fiber substrate, which blocks heat transfer between the heat-generating parts and the outside environment. Nano-ceramic aerogel composite material is produced using high-temperature resistant ceramic fiber composite technology through impregnation sol, gelation, solvent replacement, and supercritical drying. It features high temperature resistance and low thermal conductivity. Due to its excellent properties such as low thermal conductivity, high temperature limit, high hydrophobicity, and lightweight, the thermal conductivity of nano-ceramic aerogel composite material can reach 0.023 W / m·K at operating temperatures below 350℃. In high-temperature pipeline sections and boilers, it achieves a cooling effect of over 10% compared to ordinary rock wool insulation. According to on-site measurements, the temperature of exposed parts of the steam pipeline was 192.5℃. Both rock wool pipes and nano-ceramic aerogel composite insulation pipes were 100mm thick. The external temperatures of the rock wool pipes were 49℃ and 50.2℃, while the external temperatures of the nano-ceramic aerogel composite material were 43.1℃ and 45.8℃, with an average temperature reduction of 5-6℃. Comparative tests conducted on high-temperature steam pipelines revealed that, compared to ordinary rock wool insulation of the same thickness, the insulation effect can save 10-12% of energy, and the long-term economic benefits of the entire pipeline after use are considerable.

[0032] It is understood that the outer wall of the pipe body 1 is the circumferential outer wall of the pipe body 1. For example, if the pipe body 1 is a circular pipe, the side of the insulation layer 2, which is composed of multiple insulation splicing parts 21, that contacts the pipe body 1 is at least circular, so that the insulation layer 2 is fitted onto the pipe body 1 to achieve the insulation effect. The external shape of the insulation layer 2, which is composed of multiple insulation splicing parts 21, can be rectangular or polygonal, and can be adapted to the needs of the usage environment. The length of the insulation layer 2 can be greater than or equal to the length of the pipe body 1, so as to maximize the insulation effect of the insulation layer 2, and can also be laid in the pre-set insulation section of the pipe body 1. Specifically, the connection part of this disclosure can be a clamp, a buckle, or a bolt connection, etc. This disclosure specifically uses a buckle detachable connection method to facilitate the installation of multiple insulation splicing parts 21.

[0033] In this embodiment, the thermal insulation splicing part 21 has a splicing part body 211 and a splicing edge 212. The splicing edge 212 is disposed at both ends of the extension direction of the splicing part body 211, and the connecting part is disposed at the splicing edge 212. In the splicing state of adjacent thermal insulation splicing parts 21, the adjacent connecting parts are snapped and fixed, and the splicing edge 212 abuts and seals.

[0034] In this embodiment, the connecting part of this disclosure is configured as a snap-fit ​​component, which is located at the splicing edge 212. For example, the number of thermal insulation connecting parts 21 is set to two, and each splicing part body 211 has a snap-fit ​​component on the end face that needs to be connected. It can be understood that the snap-fit ​​component on the splicing part body 211 to be spliced ​​should be configured with a male end and a female end to achieve snap-fit ​​fixation. Furthermore, after the two splicing part bodies 211 are spliced, the snap-fit ​​component should not occupy space at the splicing point, thereby achieving contact sealing at the splicing edge 212. For example, a mounting groove is provided on the splicing edge 212 so that the snap-fit ​​component is set in the mounting groove. The snap-fit ​​component set in the mounting groove is coplanar with the splicing surface of the splicing edge 212. The snap-fit ​​part of the snap-fit ​​component snaps into the inside of the two, so that the splicing edges 212 are sealed by contact. Alternatively, the snap-fit ​​component is provided with a connector, which is set in the mounting groove. The connector set in the mounting groove is coplanar with the splicing surface of the splicing edge 212. The snap-fit ​​component is connected to the connector and is set outside the splicing part body 211 for snap-fit, so that the snap-fit ​​component does not occupy space at the splicing point.

[0035] In this embodiment, the splicing edge 212 is set as a sloping surface.

[0036] In this embodiment, to prevent poor insulation due to loose seams during the splicing process of the splicing body 211, the splicing edge 212 is set as a sloping surface. The sloping surface allows the external and internal splicing seams to be staggered, which can better achieve the sealing at the splice. Furthermore, the sloping surface is set at 45 degrees to facilitate installation.

[0037] In this embodiment, the connecting part includes a protruding clip 31 and a recessed clip 32. The protruding clip 31 and the recessed clip 32 are respectively disposed on the splicing edges 212 at both ends of the splicing part body 211, and the recessed clip 32 is embedded in the splicing edge 212.

[0038] In this embodiment, the joint of this disclosure includes a convex clip 31 and a concave clip 32, which are respectively disposed on the splicing edges 212 at both ends of the splicing part body 211, and the concave clip 32 is embedded in the splicing edge 212. Specifically, the two ends of the splicing part body 211 are respectively set as a first splicing edge and a second splicing edge, the convex clip is disposed on the first splicing edge, and the concave clip is disposed on the second splicing edge. For example, if there are two thermal insulation splicing parts 21, then the first splicing edge of the first thermal insulation splicing part and the second splicing edge of the second thermal insulation splicing part 21 are correspondingly disposed and spliced ​​together.

[0039] In this embodiment, multiple connecting parts are provided, and the multiple connecting parts are spaced apart along the extension direction of the splicing edge 212.

[0040] In this embodiment, multiple connecting parts are provided, and the multiple connecting parts are spaced apart along the extension direction of the splicing edge 212, so as to guide the multiple heat insulation splicing parts 21 during splicing and also to improve the fixing effect of the multiple heat insulation splicing parts 21.

[0041] In this embodiment, a reinforcing insulation layer is also included. The reinforcing insulation layer is sleeved on the insulation layer 2 and is used to seal the insulation layer 2 between the reinforcing insulation layer 2 and the pipeline body 1.

[0042] In this embodiment, a reinforcing insulation layer 2 is further included. The reinforcing insulation layer 2 is fitted over the insulation layer 2 and seals the insulation layer 2 between the reinforcing insulation layer 2 and the pipeline body 1. The reinforcing insulation layer 2 can be selected from one or more of rock wool, resin, paint, and plastic fiber. Further, the reinforcing insulation layer 2 includes a fiberglass cloth layer and a paint layer, with the fiberglass cloth layer disposed between the paint layer and the insulation layer 2. The fiberglass cloth layer is an industrial fiberglass product; specifically, flame-retardant fiberglass cloth is selected in this disclosure. Flame-retardant fiberglass cloth is made by coating one or both sides of the fiberglass cloth with a flame-retardant coating. The paint layer of this disclosure can better seal the gap between the insulation layer 2 and the reinforcing insulation layer, enhancing the insulation effect of the pipeline body 1. Specifically, the paint layer in this disclosure is set as an insulating paint, which has a wide temperature resistance range and a thermal conductivity of 0.03 W / (m·K).

[0043] In this embodiment, the number of thermal insulation splicing parts 21 is set to four.

[0044] In this embodiment, such as Figure 4 As shown, the number of insulation splicing parts 21 disclosed herein is set to four for ease of transport and on-site installation. Specifically, in an embodiment where the splicing edges 211 are sloped surfaces, the four insulation splicing parts 21 are divided into four sections: A, B, C, and D, each insulation splicing part 21 being a quarter circle. Because the sloped surfaces need to be spliced ​​together, AB can be set with the same structure, and CD can be set with the same structure, with AB and CD positioned opposite each other, and then spliced ​​together. The eight splicing edges 211 of the four insulation splicing parts 21 can be joined together to form a contact seal. In another embodiment, the four sections A, B, C, and D can be set with the same structure, and the four sections are joined end to end for contact seal.

[0045] In embodiments where the splicing edge 211 is not limited to a sloping surface, the four parts A, B, C, and D are set as quarter circles with the same structure, and the splicing edge 211 is set as a plane. When splicing, the splicing edges 211 of the four parts are aligned.
