Description

Technical Field

[0001] This application relates to the field of thermal power generation, specifically to a support structure system for tower equipment. Background Technology

[0002] With economic development and increased attention to climate change, CCUS (carbon capture, utilization, and storage) has seen rapid development in existing thermal power plants. However, the overall layout of CCUS projects in existing thermal power plants is often constrained by site limitations, making it impossible to design separate water scrubbing towers and absorption towers as is common practice. Currently, absorption towers and water scrubbing towers in thermal power plants are generally arranged independently, using traditional freestanding metal towers. The disadvantages of this approach are: independent arrangement of absorption and water scrubbing towers occupies more space, increasing project land use; the height of the independent freestanding design of absorption and water scrubbing towers is limited; the tower walls of independent freestanding designs are thicker; and the need for piping supports increases costs. Furthermore, combining the water scrubbing and absorption towers into one unit results in a large tower volume, height, and heavy load on internal packing and piping, making the traditional freestanding metal tower method unsuitable. Summary of the Invention

[0003] The purpose of this application is to provide a support structure system for a tower-type equipment, which supports a metal tower that combines a washing tower and an absorption tower, so that the metal tower itself no longer bears the load of the internal packing and pipes, thereby reducing the thickness of the metal tower wall and increasing the tower capacity.

[0004] This application discloses a support structure system for tower equipment, including: A water-washing absorption metal tower, the metal tower including a water-washing section and an absorption section along the height direction, and at least one packing layer disposed inside the tower; An outer steel-concrete composite frame structure is installed on the outside of the metal tower and is used to support the metal tower. The outer steel-concrete composite frame structure includes concrete lateral force resisting members located vertically at the four corners of the outer periphery of the water washing and absorption metal tower, and multi-layer trusses connecting adjacent concrete lateral force resisting members. The height of each layer of the truss corresponds to the height of the filler layer. A supporting member connects the metal tower to the truss of each layer. The supporting member is connected to the truss without penetrating the metal tower wall, so that the load of each filling layer is transferred to the outer steel-concrete composite frame structure through the supporting member.

[0005] In a preferred embodiment, the truss includes an upper chord, a lower chord, and a plurality of connecting rods connecting the upper chord and the lower chord.

[0006] In a preferred embodiment, the concrete lateral force resisting members at the four corners and the truss form a rectangular frame structure in a top view.

[0007] In a preferred embodiment, the support member of each of the packing layers includes an inner support member located inside the metal tower and an outer support member located outside the metal tower. The inner support member is used to provide support for the packing layer inside the metal tower, and the outer support member is used to provide support for the packing layer outside the metal tower. The inner support member and the outer support member clamp the tower wall of the metal tower relative to each other, so that the tower wall is sandwiched between them and connected to each other. In this way, the load of the filler layer is transferred from the inner support member to the outer support member and further to the outer steel-concrete composite frame structure without penetrating the tower wall. The tower wall only bears the local pressure generated by the clamping action and does not bear the load of the filler layer.

[0008] In a preferred embodiment, the external support member includes a load-bearing beam, the outer end of which is supported by a support bracket mounted on a vertical member of the truss, the support bracket being positioned toward the metal tower, so that the load of the filler layer is transferred to the outer steel-concrete composite frame structure via the support member and the support bracket.

[0009] In a preferred embodiment, a plurality of bearing beams are provided at a height corresponding to each of the packing layers, and the plurality of bearing beams are spaced apart along the four sides of the water washing absorption metal tower.

[0010] In a preferred embodiment, the upper surface of the supporting bracket body has a contact layer for supporting the load-bearing beam, and a cover plate is provided above the contact layer. The distance between the cover plate and the contact layer is used to accommodate the load-bearing beam to limit the displacement of the load-bearing beam in the vertical direction.

[0011] In a preferred embodiment, screw holes are provided at corresponding positions on the upper surface of the cover plate and the supporting beam, and the cover plate is detachably connected to the supporting beam by bolts passing through the screw holes.

[0012] In a preferred embodiment, the internal support member includes a stainless steel beam connected to the inner side of the metal tower wall, and the load-bearing beam welded to the corresponding position on the outer side of the metal tower wall. The load-bearing beam rests on the outer truss node or on the steel bracket.

[0013] In a preferred embodiment, the upper surface of the truss is covered with a grating, which is fixedly or detachably connected to the truss to form an inspection and maintenance platform for personnel passage and maintenance on the outer steel-concrete composite frame structure.

[0014] In a preferred embodiment, an auxiliary equipment support member is also provided on the outer steel-concrete composite frame structure to bear the load of the pipelines and auxiliary equipment inside the tower and transfer it to the outer steel-concrete composite frame structure.

[0015] In this embodiment, since the washing and absorption sections of the combined metal washing tower are stacked along the height direction within the same tower body, and one or more layers of filler and internal components are arranged inside the tower, the vertical concentrated loads generated by the filler and internal components, as well as the additional loads generated by external pipes and auxiliary equipment, if directly borne by the metal tower wall, could easily lead to stability risks such as local deformation and stress concentration of the tower wall. At the same time, thickening the tower wall for load-bearing purposes would significantly increase manufacturing and installation costs and would not be conducive to durability. Therefore, this application establishes an independent outer steel-concrete composite frame structure on the outside of the metal tower. The four corner concrete lateral force resisting members provide overall wind and earthquake resistance and lateral stiffness, while the multi-layer trusses corresponding to the elevation of the filler layer provide a layered load-bearing platform. The loads of each filler layer inside the tower are then transferred to the outer frame through supporting members. This achieves a division of force where the tower wall mainly bears the medium pressure and its own weight, while the heavy loads of the filler layers are borne by the outer system, reducing the risk of tower wall load-bearing and deformation and improving overall stability.

[0016] Furthermore, by using the inner and outer support components to clamp the tower wall and achieve a connection that does not penetrate the tower wall, the load of each packing layer is bypassed by the tower wall and transferred to the outer frame via the inner and outer support components. This maintains the integrity and sealing of the tower wall while avoiding the tower wall bearing the load of the packing layer and reducing the risk of local deformation and stress concentration of the tower wall.

[0017] The specification of this application contains numerous technical features distributed across various technical solutions. Listing all possible combinations of these technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described invention, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described. Attached Figure Description

Detailed Implementation

[0019] In the following description, many technical details are presented to help the reader better understand this application. However, those skilled in the art will understand that the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0020] This application has at least the following advantages: 1. This invention provides an external steel-concrete composite frame structure system that integrates a water washing / absorption tower. The load of each layer of filler inside the tower is transferred to the external truss beam through the supporting components, and the pipeline load acts directly on the external supporting structure system. This can effectively reduce the thickness of the internal metal tower wall, increase the tower capacity, reduce the project land use, and reduce project investment.

[0021] 2. This invention proposes that in areas with an earthquake intensity of 7 degrees, when the tower height is less than 50 meters, or in areas with an earthquake intensity of 6 degrees, when the tower height is less than 55 meters, a steel-concrete composite frame structure system be set up around the tower to bear the load of the filling material and pipelines in each layer of the tower. This can effectively reduce the thickness of the tower wall, increase the height of the tower, solve the problem of land shortage and reduce costs.

[0022] 3. The supporting structure system of this application can significantly improve the overall stability and load-bearing capacity of the two-tower integrated water washing and absorption metal tower, enabling it to achieve a construction height of approximately 94.8m in engineering applications.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0024] This application relates to a support structure system for a tower-type equipment, the structural diagram of which is shown below. Figure 1As shown, the tower-type equipment is a water washing and absorption metal tower. The metal tower includes a water washing section and an absorption section along its height, and at least one layer of packing material disposed within the tower, including: An outer steel-concrete composite frame structure is set outside the metal tower and used to support the metal tower. The outer steel-concrete composite frame structure includes concrete lateral force resisting members located vertically at the four corners of the outer perimeter of the water washing and absorbing metal tower, and multi-layer trusses connecting adjacent concrete lateral force resisting members. The height of each truss layer corresponds to the height of the filler layer. Supporting members connect the metal tower to the trusses of each floor. The supporting members are connected to the trusses without penetrating the metal tower walls, so that the load of each filler layer is transferred to the outer steel-concrete composite frame structure through the supporting members.

[0025] In existing thermal power plant projects, absorption towers and washing towers are typically arranged independently, often employing self-supporting metal tower structures to perform the absorption and washing processes separately. This independent arrangement presents several challenges. First, it requires the separate installation of two towers and their foundations within the plant area, consuming significant space and increasing project land use and layout complexity. Second, as the height of the self-supporting metal tower increases, its structural design is often constrained by overall stability, wind loads, and seismic forces. To meet strength and stability requirements, it is usually necessary to increase the tower wall thickness or incorporate more reinforcing structures, leading to increased material consumption and higher manufacturing and installation costs. Furthermore, with separate absorption and washing towers, inter-tower connections and external pipelines typically require separate pipe supports and maintenance access, further increasing the overall system cost and on-site construction workload.

[0026] Against this backdrop, combining the water scrubbing tower and the absorption tower into one unit, integrating the water scrubbing section and the absorption section along the same height within the same tower body, is beneficial for reducing the number of towers and the floor space required. The process of this combined water scrubbing absorption metal tower requires that the flue gas and solution achieve sufficient contact, mass transfer, and entrainment control within the same tower body. Taking the scrubbing absorption tower as an example, the flue gas can enter the lower part of the carbon dioxide absorption section from the top outlet of the alkaline scrubbing section, contacting the composite amine solvent flowing downwards to remove more than 90% of the carbon dioxide from the flue gas. The amine solution after absorbing carbon dioxide forms a rich liquid and collects at the bottom of the absorption tower. A scrubbing section is set at the top of the absorption tower to capture the amine mist entrained in the flue gas and condense the moisture in the flue gas to maintain the system's water balance. The tail gas is scrubbed by the water scrubbing section and then discharged through the upper chimney. The scrubbing water is stored in a tank and cooled before being recycled back to the absorption section.

[0027] To achieve the above process, multiple functional units are usually arranged along the height direction inside the tower. For example, the water washing section can adopt a spray washing structure and be equipped with a gas distributor and a washing water spray layer. The alkali washing section can be equipped with alkali washing packing and distributor, as well as liquid / oil collecting components and a demister above them. The absorption section can be equipped with liquid collecting components, absorption packing, redistributors, interstage cooling distributors, lean liquid distributors, as well as amine recovery packing and spray washing layers at different elevations to meet the requirements of segmented mass transfer, redistribution, demisting and heat management.

[0028] When the water washing tower and the absorption tower are combined into one, the above-mentioned process configuration will form multiple levels of packing layers and internal systems inside the tower, resulting in significant vertical dead load and additional operating load. At the same time, the tall tower body also needs to withstand wind load, lateral force and torsional effect caused by earthquake. If the traditional scheme of self-supporting tower wall is used, it is often necessary to significantly thicken the tower wall or set up a large number of through-wall supports and reinforced structures, which can easily introduce reliability problems such as local stress concentration and increase the difficulty of manufacturing and installation.

[0029] Therefore, the technical concept of this application is to make the metal tower wall mainly bear the pressure generated by the medium and its own weight, while transferring the vertical load of each packing layer and its internal components, as well as the load of external pipelines and auxiliary equipment, to the outside through an independent external support system, thereby avoiding the above problems as much as possible.

[0030] Based on the above concept, this application sets up an outer steel-concrete composite frame structure on the outside of the water washing and absorption metal tower. The outer structure is formed by a frame system in the plane by concrete lateral force resisting members arranged vertically at the four corners and multi-layer trusses connecting adjacent corner members. The load of the filling layer inside the metal tower is transferred to the outside through the supporting members to achieve the purpose of this application.

[0031] In some embodiments, a truss may include an upper chord, a lower chord, and a plurality of connecting rods connecting the upper chord and the lower chord. Specifically, the truss includes an upper chord and a lower chord extending along the length of the truss, wherein the connecting rods may include diagonal connecting rods and / or vertical connecting rods to form a plurality of triangular load-bearing units, thereby meeting the load-bearing and stiffness requirements of the truss units.

[0032] The water washing absorption metal tower of this application preferably adopts a rectangular tower body. The reason is that the support structure system of this application sets an outer steel-concrete composite frame structure on the outside of the tower body. The outer frame forms a rectangular frame in the top view, and multi-layer trusses are set at the elevations corresponding to each filler layer as external load-bearing layers. When the metal tower is rectangular, the four sides of the tower wall and the four sides of the outer rectangular frame are corresponding in the plane, so that the support components can be connected from the tower wall to the truss in a relatively direct and symmetrical manner at each corresponding elevation. The connection distance is relatively constant within the same side range, which facilitates the arrangement, standardized processing and installation positioning of the support components, and also helps to form a uniform force transmission path.

[0033] Correspondingly, the concrete lateral force resisting members at the four corners and the truss form a rectangular frame structure when viewed from above.

[0034] Since the interior of the metal tower may have multiple layers of filler material according to actual construction needs, multiple layers of the aforementioned trusses can be set along the height of the metal tower. Each truss layer is located at an elevation corresponding to the filler material layer inside the tower and is connected to the concrete lateral force resisting members located at the four corners of the outer perimeter of the metal tower, thereby forming a layered load-bearing frame around the tower body.

[0035] Of course, in some other embodiments, in addition to being set at the elevation corresponding to the packing layer, the truss can also be set at other elevations according to the structural stress, equipment layout and maintenance access requirements, such as at the elevation corresponding to tower internals such as distributors, demisters, and liquid collection components, and / or at the elevation corresponding to pipe inlets, platform passages, and equipment support points, so as to provide additional load-bearing and connection nodes, form the support boundary of the maintenance platform, or strengthen the integrity and rigidity of the outer frame in a local area.

[0036] In some embodiments, the support members for each packing layer may include an inner support member located inside the metal tower and an outer support member located outside the metal tower. The inner support member is used to provide support for the packing layer inside the metal tower, and the outer support member is used to provide support for the packing layer outside the metal tower.

[0037] The inner and outer support members clamp the tower wall of the metal tower in a relatively arranged manner, so that the tower wall is sandwiched between the two and relatively connected. In this way, the load of the filling layer is transferred from the inner support member to the outer support member and further to the outer steel-concrete composite frame structure without penetrating the tower wall. The tower wall only bears the local pressure generated by the clamping effect and does not bear the load of the filling layer.

[0038] In some alternative embodiments, the external support members may include load-bearing beams, the outer ends of which are supported by support brackets mounted on vertical members of the truss, with the support brackets facing the metal tower, so that the load of the filler layer is transferred to the outer steel-concrete composite frame structure via the support members and support brackets.

[0039] The upper surface of the supporting bracket has a contact layer for supporting the load-bearing beam. A cover plate is provided above the contact layer. The distance between the cover plate and the contact layer is used to accommodate the load-bearing beam and limit its vertical displacement. Screw holes are opened at corresponding positions on the upper surface of the cover plate and the load-bearing beam. The cover plate is detachably connected to the load-bearing beam by bolts passing through the screw holes.

[0040] In other embodiments, the outer end of the load-bearing beam is not supported by a supporting bracket, but rather by the upper surface of the upper chord of the truss. The upper chord extends along the length of the truss and forms a supporting surface. The outer end of the load-bearing beam is positioned vertically opposite the upper chord, so that the bottom of the outer end of the load-bearing beam contacts the top surface of the upper chord, transferring the end reaction force of the load-bearing beam to the truss. Furthermore, to improve the local bearing capacity of the nodes, vertical stiffening ribs can be provided within the upper and lower chords.

[0041] In some embodiments, a grating is laid on the upper surface of the truss. The grating can be fixedly or detachably connected to the truss to form an inspection and maintenance platform for personnel passage and maintenance on the outer steel-concrete composite frame structure. Specifically, the grating can be a steel grating plate, which is laid along the length of the truss on the upper chord and / or the upper supporting members of the truss. Multiple grating plates can be spliced ​​together to form a continuous platform surface. The grating and the truss can be fixed by fasteners, grating clamps, connecting plates, or welding to prevent relative slippage under operating vibration or maintenance loads. For ease of installation and maintenance, the grating preferably adopts a detachable connection method, allowing the grating plates to be quickly assembled and disassembled without disassembling the main truss components. This facilitates the inspection, maintenance, or replacement of truss nodes, supporting components, and pipelines and auxiliary equipment on the outside of the tower.

[0042] Regarding platform layout, inspection and maintenance platforms can be set along the four sides of the rectangular frame, and corners can be formed at the corners adjacent to the concrete lateral force resisting components to achieve encircling access around the tower. Multi-layer trusses set at different elevations can form different levels of maintenance platforms for inspecting external connection nodes and supporting components related to the corresponding filler layer. Kickboards and / or guardrail mounting bases can also be installed at the platform edges to reduce the risks of working at height.

[0043] The concrete lateral force resisting members are vertical reinforced concrete lateral force resisting units set at the four corners of the outer steel-concrete composite frame structure. They are continuously arranged along the height direction and are used to bear and transmit horizontal forces generated by wind loads, seismic actions, etc., and the resulting bending moments, shear forces, and torques. A single concrete lateral force resisting member is preferably a frame structure in plan view, including four vertical members and connecting members. The connecting members connect adjacent vertical members to enclose and form the frame structure, creating a vertically penetrating cavity. This cavity can be used as a functional space, such as for accommodating elevator shafts and / or maintenance shafts. Correspondingly, trusses and their maintenance platforms set at different elevations can connect to the entrances and exits of this vertical cavity to form maintenance paths that facilitate vertical access and horizontal passage for personnel.

[0044] To verify the lateral stiffness and torsional performance of the supporting structure system proposed in this application in a two-tower integrated high-rise tower structure, structural calculations were also performed on the external steel-concrete composite frame structure. The cumulative height of the calculated structure reached 94.800m, as shown in Table 1. Table 1 Table 2 shows the calculation results of the maximum floor displacement of the structural system in this application under X-direction bidirectional seismic loading. The maximum inter-story drift angle in the X direction is 1 / 978. Table 2 Table 3 shows the maximum floor displacements of the structural system in this application under Y-direction seismic loading, with the maximum inter-story drift angle in the Y direction being 1 / 1086. Table 3 Table 4 shows the maximum floor displacements under wind loads in the ±X direction, with the maximum inter-story drift angle in the X direction being 1 / 791. Table 4 Table 5 shows the maximum floor displacements under wind loads in the ±Y direction, with the maximum inter-story drift angle in the Y direction being 1 / 1029. Table 5 Table 6 summarizes the main indicators of the supporting structure system of this application. As shown in Table 6, after applying the supporting structure system of this application, the combined two-tower water-washing absorption metal tower can still meet the requirements under wind load and seismic action under the condition of a tall layout. The ratio of the maximum inter-story displacement to the story height meets the limit requirement of 1 / 550, and the structural torsional effect index meets the requirement of ≤1.5. This indicates that the supporting structure system can provide a reliable external bearing and lateral force resisting foundation for the combined two-tower tower equipment, and support its construction height of approximately 94.8m.
