Abstract
Description
Technical Field
[0001] This application relates to the field of tank insulation technology, and in particular to a large horizontal tank insulation structure. Background Technology
[0002] Large horizontal tanks are steel containers widely used in petroleum, chemical, and metallurgical industries. They possess the ability to withstand high positive and negative pressures, which helps reduce oil evaporation losses and decreases the risk of fire. Depending on the medium stored, some large horizontal tanks may require insulation.
[0003] In the existing technology, large horizontal tanks are usually formed by continuously wrapping insulation tape around the surface in an axial direction to form an insulation structure. When the wrapping spacing is large, there may be leaks that are not covered, resulting in poor insulation effect. Moreover, the insulation structure formed by wrapping is uneven, with the overlapping area being thicker than the non-overlapping area, resulting in an inconsistent overall thickness of the insulation structure and inconsistent insulation effect in different areas of the tank. Summary of the Invention
[0004] To address the shortcomings and deficiencies of the aforementioned background technology, this application provides a large horizontal tank insulation structure that uses an axially segmented approach to wrap the tank, which can completely and smoothly cover the surface of the tank, avoid leaks on the surface of the tank, and ensure the insulation effect.

An outer splicing seam is formed between two adjacent outer insulation blankets, and the inner splicing seam and the outer splicing seam are spatially offset.

[0011] A second intermediate layer splicing seam is formed between two adjacent sections of the second intermediate layer insulation blanket, and the second intermediate layer splicing seam is spatially offset from the outer layer splicing seam.
[0012] In some embodiments, both the inner insulation layer and the outer insulation layer are three-section structures, the three-section structure including a middle section and connecting sections located on both sides of the middle section.
[0013] In some embodiments, the inner insulation layer has spaced notches on both edges of the tank in the axial direction.
[0014] In some embodiments, the inner insulation layer includes multiple reflective layers and multiple spacer layers, with a single spacer layer disposed between two adjacent reflective layers; the inner insulation layer has the same structure as the outer insulation layer.
[0015] In some embodiments, the inner insulation blanket and the outer insulation blanket are fixedly connected by a number of rivets.
[0016] In some embodiments, the rivet includes a rivet sleeve for penetrating the insulation blanket and a core rod for pressing into the rivet sleeve to cause the end of the rivet sleeve to expand and clamp the insulation blanket.

[0021] Because multiple inner and outer insulation layers are used for covering, the inner insulation layers are sequentially spliced along the axial direction of the tank and wrapped around the outer surface of the inner insulation layer, and the outer insulation layers are sequentially spliced along the axial direction of the tank and wrapped around the outer surface of the inner insulation layer.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments 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.
[0032] To address the shortcomings and deficiencies of the aforementioned background technology, this application provides a large horizontal tank insulation structure that uses an axially segmented approach to wrap the tank, which can completely and smoothly cover the surface of the tank, avoid leaks on the surface of the tank, and ensure the insulation effect.
[0033] See Figures 1 to 6 As shown in the figure, this application provides a large horizontal tank insulation structure, including:
[0034] Tank 1, the vertical radial length of tank 1 is less than the horizontal axial length;
[0035] Multiple inner insulation blankets 2 are spliced together along the axial direction of tank body 1 and wrapped around the outer surface of tank body 1, with an inner splicing seam formed between adjacent two inner insulation blankets 2.
[0036] Multiple outer insulation blankets 3 are sequentially spliced along the axial direction of the tank body 1 and wrapped around the outer surface of the inner insulation blanket 2. An outer splicing seam is formed between two adjacent outer insulation blankets 3, and the inner splicing seam and the outer splicing seam are spatially offset.
[0037] The large horizontal tank insulation structure of this application uses multiple inner insulation blankets 2 and multiple outer insulation blankets 3 for covering. The multiple inner insulation blankets 2 are sequentially spliced along the axial direction of the tank 1 and wrapped around the outer surface of the inner insulation blankets 2. The multiple outer insulation blankets 3 are sequentially spliced along the axial direction of the tank 1 and wrapped around the outer surface of the inner insulation blankets 2. Adjacent inner insulation blankets 2 are flatly joined together, and adjacent outer insulation blankets 3 are flatly joined together. At the same time, the inner layer splicing seams and the outer layer splicing seams are spatially staggered. Therefore, the surface of the tank 1 can be completely and flatly covered, avoiding leakage points on the surface of the tank 1, thereby ensuring the heat insulation effect.
[0038] For example, in this embodiment, the inner insulation blanket 2 and the outer insulation blanket 3 can be fixedly connected by stitching and bonding. The inner insulation blanket 2 is flatly joined at both ends along the circumference of the tank body, and the outer insulation blanket 3 is flatly joined at both ends along the circumference of the tank body. In this embodiment, the axial misalignment width formed by the misalignment of the splicing seam between the outer insulation blanket 3 and the inner insulation blanket 2 is greater than 200mm, and the circumferential misalignment length formed by the misalignment of the splicing seam between the inner insulation blanket 2 and the outer insulation blanket 3 is greater than 200mm.
[0039] In some alternative embodiments: see Figures 1 to 6 As shown, this application embodiment provides a large horizontal tank insulation structure. The large horizontal tank insulation structure has a first intermediate insulation layer 4 and a second intermediate insulation layer 5 between the inner insulation layer 2 and the outer insulation layer 3. The second intermediate insulation layer 5 is wrapped around the outer surface of the first intermediate insulation layer 4.
[0040] In this embodiment of the application, a first intermediate insulation layer 4 and a second intermediate insulation layer 5 are also provided between the inner insulation layer 2 and the outer insulation layer 3, which can form a four-layer wrapping of the tank body 1, further improving the heat insulation effect of the tank body 1.
[0041] In some alternative embodiments: see Figures 1 to 6 As shown, this application embodiment provides a large horizontal tank insulation structure. The large horizontal tank insulation structure has a first intermediate layer splicing seam between two adjacent sections of the first intermediate layer insulation 4. The first intermediate layer splicing seam and the inner layer splicing seam are spatially misaligned.
[0042] A second intermediate layer splicing seam is formed between two adjacent sections of the second intermediate layer insulation 5, and the second intermediate layer splicing seam is spatially offset from the outer layer splicing seam.
[0043] In this embodiment, the two ends of the first intermediate layer insulation blanket 4 are misaligned with the two ends of the inner layer insulation blanket 2, which allows the first intermediate layer splice seam formed by the first intermediate layer insulation blanket 4 to be spatially misaligned with the inner layer splice seam. Similarly, the two ends of the second intermediate layer insulation blanket 5 are misaligned with the two ends of the outer layer insulation blanket 3, which allows the second intermediate layer splice seam formed by the second intermediate layer insulation blanket 5 to be spatially misaligned with the outer layer splice seam, thereby further ensuring the heat insulation effect of the tank body 1.
[0044] In some alternative embodiments: see Figures 1 to 6 As shown in the embodiment of this application, a large horizontal tank insulation structure is provided. The inner insulation layer 2 and the outer insulation layer 3 of the large horizontal tank insulation structure are both three-section structures, including a middle section and connecting sections located on both sides of the middle section.
[0045] In this embodiment, both the inner insulation blanket 2 and the outer insulation blanket 3 are three-section structures. When the width of the insulation blanket needs to be adjusted, the width of the insulation blanket can be increased by adding the middle section, which makes it convenient to adjust the width of the insulation blanket coverage and achieve full coverage of the surface of the tank 1.
[0046] For example, in this embodiment, the middle section and the connecting section can be connected together by stitching or bonding. At the same time, the first intermediate layer insulation blanket 4 and the second intermediate layer insulation blanket 5 set between the inner layer insulation blanket 2 and the outer layer insulation blanket 3 can also be spliced in segments to widen the insulation blanket. The splicing seams on the first intermediate layer insulation blanket 4 and the second intermediate layer insulation blanket 5 are staggered.
[0047] In some alternative embodiments: see Figures 1 to 6 As shown, this application embodiment provides a large horizontal tank insulation structure. The inner insulation layer 2 of the large horizontal tank insulation structure has notches 6 spaced apart on both edges in the axial direction of the tank 1.
[0048] In this embodiment, the inner insulation blanket 2 has spaced notches 6 on both edges of the tank 1 in the axial direction. The notches 6 facilitate the edge of the inner insulation blanket 2 to fit against the surface of the tank 1, achieving the purpose of the insulation blanket floating on the surface of the tank 1 without wrinkles. It should be noted that in this embodiment, the notches 6 extend along the axial direction of the tank 1 and are covered by the outer insulation blanket 3, thus preventing insulation leaks.
[0049] In some alternative embodiments: see Figures 1 to 6 As shown in the figure, this application embodiment provides a large horizontal tank insulation structure. The inner insulation layer 2 of the large horizontal tank insulation structure includes multiple reflective layers and multiple spacer layers, and a single spacer layer is provided between two adjacent reflective layers. The inner insulation layer 2 has the same structure as the outer insulation layer 3.
[0050] The inner insulation layer 2 of this embodiment consists of alternating reflective layers and spacer layers. Neither the reflective layer nor the spacer layer is shown in the figure. The reflective layer is made of a material with high reflectivity and low emissivity, so that the radiant heat of the previous layer can be partially reflected by the radiation screen of the current layer, while the remaining energy is transferred to the next layer and reflected again.
[0051] For example, the spacer layer is mainly composed of materials with low thermal conductivity, such as glass fiber, nylon, mesh, and foam, which can reduce solid thermal conductivity between adjacent reflective layers. For example, in this embodiment, the inner insulation blanket 2 uses a double-sided aluminized film as the reflective layer and non-woven fabric as the spacer layer. The outer insulation blanket 3, the first intermediate insulation blanket 4, and the second intermediate insulation blanket 5 all have the same structure as the outer insulation blanket 3.
[0052] In some alternative embodiments: see Figures 1 to 6 As shown in the figure, this application embodiment provides a large horizontal tank insulation structure, wherein the inner insulation layer 2 and the outer insulation layer 3 of the large horizontal tank insulation structure are fixedly connected by a number of rivets.
[0053] In this embodiment, the inner insulation blanket 2 and the outer insulation blanket 3 are fixedly connected by a number of rivets, which can form a multi-point fixation and has the advantage of convenient installation. For example, the rivets in this embodiment are nylon rivets. When a first intermediate insulation blanket 4 and a second intermediate insulation blanket 5 are provided between the inner insulation blanket 2 and the outer insulation blanket 3, a number of rivets can be used to fix and connect each two insulation blankets.
[0054] In some alternative embodiments: see Figures 1 to 6 As shown, this application embodiment provides a large horizontal tank insulation structure. The rivets of the large horizontal tank insulation structure include rivet sleeves 7 for penetrating the insulation blanket and core rods 10 for pressing into the rivet sleeves 7 to expand and clamp the end of the rivet sleeves 7 to the insulation blanket.
[0055] In this embodiment of the application, the inner insulation blanket 2 and the outer insulation blanket 3 are provided with perforations. The rivet sleeve 7 is inserted through the inner insulation blanket 2 and the outer insulation blanket 3. By pressing in the rivet, the end of the rivet sleeve 7 can expand and clamp the insulation blanket, thereby playing a fixing role.
[0056] In some alternative embodiments: see Figures 1 to 6 As shown in the embodiment of this application, a large horizontal tank insulation structure is provided. One end of the nail sleeve 7 of the large horizontal tank insulation structure is provided with an outwardly protruding annular flange 8, and the other end is provided with an axially extending strip groove 9. The inner diameter of the nail sleeve 7 gradually decreases in the direction away from the annular flange 8.
[0057] In this embodiment, the nail sleeve 7 has an outwardly protruding annular flange 8 integrally formed at one end. When the nail sleeve 7 is inserted into the insulation blanket, the annular flange 8 on the nail sleeve 7 can press against the surface of the insulation blanket. At the same time, since the other end of the nail sleeve 7 has an axially extending strip groove 9, and the inner diameter of the nail sleeve 7 gradually decreases in the direction away from the annular flange 8, after the nail sleeve 7 is inserted into the core rod 10, the core rod 10 squeezes the inner wall of the nail sleeve 7, which can cause the end of the nail sleeve 7 to expand and cooperate with the annular flange 8 to clamp the insulation blanket.
[0058] In some alternative embodiments: see Figures 1 to 6 As shown, this application embodiment provides a large horizontal tank insulation structure. One end of the core rod 10 of the large horizontal tank insulation structure is provided with a pressure cap 11, and the pressure cap 11 is provided with a snap-fit groove 12 for matching the annular flange 8.
[0059] In this embodiment, one end of the core rod 10 is integrally formed with a pressure cap 11, which facilitates pressing the core rod 10. The pressure cap 11 is provided with a snap-fit groove 12. After the nail sleeve 7 is inserted into the core rod 10 and pressed into place, the annular flange 8 can be snapped into the snap-fit groove 12 on the pressure cap 11, thereby preventing the core rod 10 from detaching from the nail sleeve 7 while clamping the heat insulation blanket.
