Description

Technical Field

[0001] This invention belongs to the field of flue gas purification technology, specifically relating to a flue support device. Background Technology

[0002] The layout scheme for desulfurization units in coal-fired power plants is relatively mature. Typically, absorption towers are placed on both sides of the chimney, and the absorption towers and chimneys are connected by clean flue gas ducts. In related technologies, steel supports are usually erected from the ground to support the clean flue gas ducts. This method requires a large area, consumes a large amount of steel for the supports, has a long construction period, and is costly. Other technologies use trusses between the absorption tower and the chimney to support the flue gas ducts; however, some power plant chimneys are not suitable for supporting trusses and clean flue gas ducts, and this can easily lead to deformation and damage to the stress areas of the absorption tower or chimney. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a flue support device, which utilizes an absorption tower for support on one side, reducing the amount of supporting steel used, while the rigidity of the absorption tower ensures stable support of the flue.

[0004] The flue support device of this invention includes a load-bearing component, a connecting component, and a support component. The load-bearing component is used to install and support the flue. The connecting component is used to connect the load-bearing component and an absorption tower so that the absorption tower can support at least a portion of the load-bearing component. The support component includes a column, which is connected to the load-bearing component so that the column supports at least a portion of the load-bearing component.

[0005] The flue support device of this invention uses a connecting component to connect the load-bearing component and the absorption tower, so that the absorption tower works together with the support component to support the flue without having to be placed on the chimney. The large rigidity of the absorption tower achieves stable support for the flue and saves materials.

[0006] In some embodiments, the load-bearing component is a truss, which includes a plurality of parallel upper trusses and a plurality of parallel lower trusses. Web members connect the upper trusses and the lower trusses, the plurality of upper trusses, and the plurality of lower trusses. The flue is installed between the plurality of upper trusses.

[0007] In some embodiments, the connecting assembly includes a first reinforcing rib and a second reinforcing rib. The first reinforcing rib is annular and sleeved on the outer wall of the absorption tower. There are multiple first reinforcing ribs, which are spaced apart along the height direction of the absorption tower. The second reinforcing rib is disposed between two adjacent first reinforcing ribs. There are multiple second reinforcing ribs, which are arranged along the circumference of the absorption tower.

[0008] In some embodiments, the connecting assembly further includes a support connected to at least a portion of the first reinforcing rib and at least a portion of the second reinforcing rib, and the support is connected to at least a portion of the load-bearing member.

[0009] In some embodiments, the support assembly further includes a base, wherein the column is arranged along the height direction of the absorption tower, and the base is connected to the bottom of the column.

[0010] In some embodiments, the base is a cast-in-place base, at least a portion of the column is embedded in the base, and the portion of the column embedded in the base is provided with shear studs.

[0011] In some embodiments, the base includes a first part and a second part, and a steel cage is provided inside the base, the steel cage passing through the first part and the second part, and a portion of the column is located inside the steel cage.

[0012] In some embodiments, the support assembly further includes horizontal braces and diagonal braces, wherein there are multiple columns, and the horizontal braces and diagonal braces are disposed between any two adjacent columns so that the multiple columns jointly support the load-bearing component.

[0013] In some embodiments, the support assembly further includes a support plate, one end of which is connected to the column, and the other end of which is connected to the upper or lower truss.

[0014] In some embodiments, the column is made of H-beam, which includes two side flanges and a middle plate. Multiple reinforcing plates are provided between the two side flanges, and the multiple reinforcing plates are arranged at intervals along the length of the H-beam.

[0015] The flue support device of this invention can evenly transfer the load of the flue to the tower wall of the absorption tower through the reinforcing ribs in different directions of the connecting components, thus avoiding damage to the connection of the absorption tower. At the same time, the support components use columns and bases, which are structurally stable and require less material, and do not require the construction of a chimney. Attached Figure Description

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figure 1 As shown, the flue support device of this embodiment includes a bearing component 1, a connecting component 2, and a support component 3. The bearing component 1 is used to install and support the flue 4. The connecting component 2 is used to connect the bearing component 1 and the absorption tower 5 so that the absorption tower 5 can support at least a portion of the bearing component 1. The support component 3 includes a column 31, which is connected to the bearing component 1 so that the column 31 supports at least a portion of the bearing component 1.

[0026] The core function of the flue support device in this embodiment of the invention is to provide stable support for the flue 4 of the absorption tower 5. The flue 4 is installed and supported by a bearing component 1, one side of which is connected to the absorption tower 5 via a connecting component 2, utilizing the tower body of the absorption tower 5 for support. The other side of the bearing component 1 is supported by a support component 3. Due to the large overall size and high rigidity of the absorption tower 5, it can stably support the bearing component 1 and the flue 4. By transferring a portion of the force on the flue 4 to the absorption tower 5 in this way, the stress on the support component 3 can be reduced. Furthermore, the amount of steel used in the support component 3 can be reduced; only a small amount of steel is needed to form a simple bracket to support the bearing component 1. In this embodiment, the bearing component 1 is supported on one side by the absorption tower 5 and on the other side by the support component 3, eliminating the need to attach the bearing component 1 to the chimney, which is more in line with operational standards and avoids damage to the chimney caused by the bearing component 1 and the flue 4.

[0027] In some embodiments, the supporting component 1 is a truss, which includes a plurality of parallel upper trusses and a plurality of parallel lower trusses. Web members are connected between the upper trusses and the lower trusses, between the plurality of upper trusses, and between the plurality of lower trusses. The flue 4 is installed between the plurality of upper trusses.

[0028] The truss in the flue support device of this invention is lightweight and has a high load-bearing capacity. The truss includes multiple upper trusses and multiple lower trusses, all of which are arranged in parallel. The parallel arrangement of the upper trusses forms a stable foundation for the flue 4, while the parallel arrangement of the lower trusses forms a quadrilateral structure, making the entire truss structure more stable. Furthermore, the number of upper and lower trusses can be flexibly adjusted according to the length and weight of the flue 4. The web members are arranged diagonally or vertically, which effectively transmits the shear force and bending moment between the upper and lower trusses, further improving the strength of the truss and reducing the amount of material used.

[0029] In some embodiments, the connecting component 2 includes a first reinforcing rib 21 and a second reinforcing rib 22. The first reinforcing rib 21 is annular and sleeved on the outer wall surface of the absorption tower 5. There are multiple first reinforcing ribs 21, which are spaced apart along the height direction of the absorption tower 5. The second reinforcing rib 22 is disposed between two adjacent first reinforcing ribs 21. There are multiple second reinforcing ribs 22, which are arranged along the circumference of the absorption tower 5.

[0030] In this embodiment of the flue support device, the first reinforcing rib 21 has a ring-shaped structure, and its inner diameter is adapted to the outer wall diameter of the absorption tower 5. During installation, it is directly fitted onto the outer wall of the absorption tower 5 and fixed to the absorption tower 5 by welding or bolting. Multiple first reinforcing ribs 21 are provided, and multiple first reinforcing ribs 21 and second reinforcing ribs 22 form a whole, which can evenly distribute the force of the bearing component 1 to the entire tower body of the absorption tower 5, avoiding damage to the absorption tower 5 caused by excessive force at local connections. The second reinforcing ribs 22 are evenly arranged along the circumference of the absorption tower 5, such as one second reinforcing rib 22 every 30°-60°. To save materials, several second reinforcing ribs 22 can also be provided only in the area connected to the bearing component 1, which can also meet the requirements. In this embodiment, the bearing component 1 can be fixedly connected to the first reinforcing rib 21 or the second reinforcing rib 22 by welding or bolting to ensure that the entire bearing component 1 does not shake.

[0031] In some embodiments, the connecting component 2 further includes a support, which is connected to at least a portion of the first reinforcing rib 21 and at least a portion of the second reinforcing rib 22, and is connected to at least a portion of the bearing component 1.

[0032] In the flue support device of this embodiment, the support serves to connect the first reinforcing rib 21, the second reinforcing rib 22, and the load-bearing component 1. The support is also generally referred to as a corbel. One side of the support is fixedly connected to the first reinforcing rib 21 and the second reinforcing rib 22 by welding or bolts, while the other side of the support serves to support the load-bearing component 1. The support and the load-bearing component 1 are also further fixedly connected by welding or bolts.

[0033] In some embodiments, the support assembly 3 further includes a base 32, wherein the column 31 is arranged along the height direction of the absorption tower 5, and the base 32 is connected to the bottom of the column 31.

[0034] In the flue support device of this embodiment, the base 32 and column 31 in the support component 3 provide the main vertical support for the load-bearing component 1, and must have sufficient compressive strength and tensile strength. The base 32 is connected to the ground or has a certain weight, which can play a role in stable support.

[0035] In some embodiments, the base 32 is a cast-in-place base 32, at least a portion of the column 31 is embedded in the base 32, and the portion of the column 31 embedded in the base 32 is provided with shear studs 33.

[0036] In this embodiment of the flue support device, the portion of the column 31 placed in the base 32 is firmly fixed within the base 32 using shear studs 33, preventing separation between the column 31 and the base 32 and ensuring stable support of the column 31 by the base 32. The shear studs 33 are evenly distributed along the side wall of the column 31.

[0037] In some embodiments, the base 32 includes a first part 321 and a second part 322, and a steel cage 323 is provided inside the base 32. The steel cage 323 passes through the first part 321 and the second part 322, and a portion of the column 31 is located inside the steel cage 323.

[0038] In this embodiment of the flue support device, the first part 321 is placed on the ground or pre-embedded underground, forming the lower part of the base 32, and the second part 322 is connected to the column 31, forming the upper part of the base 32. The height of the first part 321 of the base 32 is approximately 1100mm, and the height of the second part 322 is approximately 1400mm. The bottom of the first part 321 is an externally enclosed column base. (See attached diagram.) Figure 3 and attached Figure 4 The externally enclosed column base, with its larger diameter, provides a larger area of ​​support, ensuring stability. The first part 321 and the second part 322 contain a steel cage 323, which gives the base higher strength and can enclose a portion of the column 31, forming a stable connection.

[0039] During the construction of the base 32, the first part 321 is constructed first, and connecting bolts or connecting steel bars are pre-embedded within the first part 321. After the construction of the first part 321 is completed, the bottom of the column 31 is further fixed to the first component using the connecting bolts or connecting steel bars reserved at the upper end of the first part 321. Subsequently, the second part 322 is constructed to achieve the embedding of the column 31 into the base 32, ensuring a stable connection between the column 31 and the base.

[0040] In some embodiments, the support component 3 further includes a horizontal brace 34 and a diagonal brace 35, wherein there are multiple columns 31, and the horizontal brace 34 and the diagonal brace 35 are disposed between any two adjacent columns 31 so that the multiple columns 31 jointly support the load-bearing component 1.

[0041] In the flue support device of this embodiment of the invention, multiple columns 31 are provided. The multiple columns 31 are connected to each other by horizontal bracing 34 and diagonal bracing 35, so that the multiple columns 31 form a whole. The multiple columns 31 can be connected to the bearing component 1 at the same time to achieve more stable support.

[0042] In some embodiments, the support assembly 3 further includes a support plate 36, one end of which is connected to the column 31, and the other end of which is connected to the upper or lower truss.

[0043] In this embodiment of the flue support device, a support plate 36 can be pre-welded to the side wall of the column 31 at the factory. Since this welding point is the main stress point between the column 31 and the load-bearing component 1, pre-welding at the factory ensures the quality of the weld and improves the strength of the connection. During on-site construction, the connection between the support plate 36 and the upper or lower truss rod is welded; this is not a major stress point, so on-site welding is sufficient. This facilitates the dispersed transportation and centralized assembly of the entire device.

[0044] In some embodiments, the column 31 is made of H-beams, which include two side flanges and a middle plate. Multiple reinforcing plates 37 are provided between the two side flanges and are spaced apart along the length of the H-beams.

[0045] See appendix Figure 5 and attached Figure 6 In this embodiment of the flue support device, the column 31 uses one or more H-beams, and the flanges and the intermediate plate are integrally formed by welding or rolling. The type of H-beam needs to be determined according to the load-bearing capacity of the column 31 to ensure that the thickness and width of the flanges and web meet the support requirements. A single reinforcing plate 37 is welded to the flange supports on both sides, and multiple reinforcing plates 37 are arranged at intervals along the length of the H-beam, further enhancing the strength of the column 31.

[0046] In some specific embodiments, the H-beams are treated with anti-corrosion measures. Since the column 31 is exposed to the outdoors or in a humid environment for a long time, hot-dip galvanizing or anti-corrosion coating is used. The primer is epoxy zinc-rich primer, and the topcoat is polyurethane topcoat, with a total thickness of not less than 150μm, to ensure that the column 31 can be used stably for a long time.
