Description

Technical Field

[0001] This application belongs to the field of energy and power technology, and in particular relates to a flow guiding structure and a non-metallic expansion joint. Background Technology

[0002] Non-metallic expansion joints, also known as non-metallic compensators, are flexible components used in pipeline and equipment systems to compensate for thermal displacement, absorb vibration, and reduce noise. They are primarily made of non-metallic materials and feature corrosion resistance, good sealing performance, light weight, and easy installation. They are widely used in pipeline systems in industries such as chemical, metallurgy, power, and environmental protection.

[0003] Non-metallic expansion joints are mainly composed of various high-temperature resistant materials. Due to their long-term operation under high temperature and harsh conditions, the internal materials of non-metallic expansion joints will quickly age and fail, causing the surface of the non-metallic expansion joint to overheat and crack, which will further lead to the ejection of hot gas, resulting in economic losses and safety accidents.

[0004] Therefore, developing a flow guiding structure and a non-metallic expansion joint to solve the technical defects of existing non-metallic expansion joints that are prone to aging and failure, has become an urgent problem for those skilled in the art. Utility Model Content

[0005] Therefore, it is necessary to provide a flow guiding structure and a non-metallic expansion joint to address the technical defects of existing technologies, such as the tendency of non-metallic expansion joints to age and fail, leading to damage.

[0006] This application provides a flow guiding structure, which includes: a first flow guiding plate and a second flow guiding plate. Both the first flow guiding plate and the second flow guiding plate are L-shaped structures. The long sides of the first flow guiding plate and the second flow guiding plate overlap and a sandwich layer is provided between them. The short sides of the first flow guiding plate and the second flow guiding plate are arranged opposite to each other.

[0007] In one embodiment, the flow guiding structure further includes a heat insulation layer disposed in the interlayer.

[0008] In one embodiment, the first guide plate is a heat-resistant stainless steel guide plate, and the second guide plate is a heat-resistant stainless steel guide plate.

[0013] In one embodiment, the thickness of the insulation layer is 2 to 4 mm.

[0014] This application also provides a non-metallic expansion joint, which includes the flow guiding structure described in any one of the above, wherein the short sides of the first flow guiding plate and the second flow guiding plate are connected to the interior of the non-metallic expansion joint body.

[0015] In summary, this application provides a flow guiding structure comprising a first flow guiding plate and a second flow guiding plate, both of which are L-shaped structures. The long sides of the first and second flow guiding plates overlap, and a sandwich layer is provided between them. The short sides of the first and second flow guiding plates are arranged opposite to each other. This application also provides a non-metallic expansion joint, comprising the aforementioned flow guiding structure, wherein the short sides of the first and second flow guiding plates are internally connected to the body of the non-metallic expansion joint. The flow guiding structure and non-metallic expansion joint provided by this application, with the first and second flow guiding plates of the flow guiding structure, effectively provide heat insulation while ensuring flow guidance.

[0022] Furthermore, 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 at least one of that feature.

[0023] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0026] Please see Figure 1 This application provides a flow guiding structure, including: a first flow guiding plate 2 and a second flow guiding plate 3. Both the first flow guiding plate 2 and the second flow guiding plate 3 are L-shaped structures. The long sides of the first flow guiding plate 2 and the second flow guiding plate 3 overlap and there is a sandwich between them. The short sides of the first flow guiding plate 2 and the second flow guiding plate 3 are arranged opposite to each other.

[0027] In the flow guiding structure provided in this application embodiment, the long sides of the first flow guiding plate 2 and the second flow guiding plate 3 of the L-shaped structure overlap. The interlayer between the first flow guiding plate 2 and the second flow guiding plate 3 can play a flow guiding role. The overlapping first flow guiding plate 2 and the second flow guiding plate 3 effectively block heat and organize the heat transfer, thus playing an effective heat insulation role.

[0028] The first guide plate 2 and the second guide plate 3 of the L-shaped structure are arranged with their long sides overlapping. They also have the advantage of strong versatility. Depending on the actual installation space, the two long sides of the L-shaped structure can be completely overlapped or partially or completely staggered, which makes them more versatile.

[0029] To further optimize the technical solution, the flow guiding structure provided in this application embodiment also includes a heat insulation layer, which is disposed in the interlayer. The heat insulation layer can further block heat conduction, thereby further enhancing the heat insulation effect of the flow guiding structure.

[0030] To further optimize the technical solution, while ensuring the good heat insulation effect of the first guide plate 2 and the second guide plate 3, the first guide plate 2 and the second guide plate 3 also have good thermal stability, and the structural stability of the guide structure can be ensured under high temperature and over-temperature conditions. In the technical solution provided in the embodiment of this application, the first guide plate 2 is a heat-resistant stainless steel guide plate, and the second guide plate 3 is a heat-resistant stainless steel guide plate.

[0031] In the technical solution provided in this application embodiment, while ensuring the heat insulation effect of the flow guiding structure, the design concept of lightweight flow guiding structure is also taken into account. The thickness of the first flow guiding plate 2 is 5-6mm, and the thickness of the second flow guiding plate 3 is 5-6mm.

[0032] To facilitate the connection and fixation of the flow guiding structure with external equipment and ensure its connection stability, the flow guiding structure provided in this application embodiment further includes: end ears 4, which are respectively disposed on the short sides of the first flow guiding plate 2 and the second flow guiding plate 3.

[0033] To further optimize the technical solution, in a flow guiding structure provided in this application embodiment, the heat insulation layer is thermal insulation cotton. Thermal insulation cotton has the advantages of low cost and good heat insulation effect, and the replacement and maintenance cost is low when aging occurs.

[0034] To further optimize the technical solution, while ensuring the flow guiding effect of the interlayer, the heat insulation effect of the flow guiding structure is avoided by preventing heat from being conducted through the interlayer. In the technical solution provided in this application embodiment, the gap width of the interlayer is 4 to 6 mm.

[0035] Similarly, in order to match the width of the gap, while considering the optimal solution of the heat insulation effect of the heat insulation layer, and without affecting the airflow of the flow guiding structure due to the installation of the heat insulation layer, the thickness of the heat insulation layer in the flow guiding structure provided in the embodiment of this application is 2 to 4 mm.

[0036] This application also provides a non-metallic expansion joint, including the above-described flow guiding structure, wherein the short sides of the first flow guiding plate 2 and the second flow guiding plate 3 are connected to the interior of the non-metallic expansion joint body.

[0037] Specifically, a non-metallic expansion joint is installed on the outside of the flue 5. The skin 1 of the non-metallic expansion joint is connected and fixed to the short sides of the first guide plate 2 and the second guide plate 3 through the end lugs 4. At this time, the airflow can pass through the gap between the first guide plate 2 and the second guide plate 3. At the same time, the first guide plate 2 and the second guide plate 3 can effectively block the high temperature heat from the flue 5, effectively avoid the thermal damage of high temperature and overheating to the non-metallic expansion joint, improve the stability of the non-metallic expansion joint in the overheating state, and solve the technical defect in the prior art that the non-metallic expansion joint is prone to aging and failure, resulting in damage.

[0038] Specifically, in practical applications, the end lug 4 can be connected and fixed to the non-metallic expansion joint body by welding, which further improves the thermal stability of the non-metallic expansion joint.

[0039] In summary, this application provides a flow guiding structure comprising a first flow guiding plate and a second flow guiding plate, both of which are L-shaped structures. The long sides of the first and second flow guiding plates overlap, and a sandwich layer is provided between them. The short sides of the first and second flow guiding plates are arranged opposite to each other. This application also provides a non-metallic expansion joint, comprising the aforementioned flow guiding structure, wherein the short sides of the first and second flow guiding plates are internally connected to the body of the non-metallic expansion joint. The flow guiding structure and non-metallic expansion joint provided by this application, with the first and second flow guiding plates of the flow guiding structure, effectively provide heat insulation while ensuring flow guidance. When installed on a non-metallic expansion joint, it can significantly improve the stability of the non-metallic expansion joint under over-temperature conditions, solving the technical defect in the prior art where non-metallic expansion joints are prone to aging and failure leading to damage.

[0040] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0041] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
