Description

Technical Field

[0001] This application relates to the field of heat storage and steam transmission, and in particular to an inlet and outlet pipeline system for a spherical heat accumulator that does not require the addition of a platform. Background Technology

[0002] In the field of steam recovery and utilization systems in steelmaking plants or power centers of steel production enterprises, the demand for efficient steam recovery and utilization is increasing with the continuous development of the steel industry. This not only concerns the energy efficiency of enterprises but also affects production costs and the expansion of production scale. A reasonable layout of the inlet and outlet piping systems for accumulators in a steam recovery and utilization system can ensure stable steam delivery and distribution, providing reliable power support for the steel production process. It also has a significant impact on the enterprise's site utilization and overall layout; an efficient piping system can save considerable space and construction costs.

[0003] Currently, to address the issue of inlet and outlet pipe layout for accumulators in steam recovery and utilization systems, horizontal accumulators are commonly used, with multiple accumulators arranged on platforms at different heights. For example, a common practice is to place horizontal accumulators on two platforms at different heights, with each inlet and outlet consisting of an inlet pipe and an outlet pipe, respectively. Simultaneously, steam pipes and associated valves and other auxiliary facilities are also located on platforms at specific heights. This arrangement is a relatively common method and can, to a certain extent, meet the basic requirements for steam transmission and distribution.

[0004] However, using multiple horizontal accumulators arranged on different platforms, with steam pipelines and auxiliary facilities also located on specific platforms, results in a large footprint. This is because space needs to be reserved for multiple platforms and equipment, leading to a relatively dispersed system layout. Furthermore, the long pipeline routes increase energy loss and construction costs during steam transport. The project is also extensive, involving the construction of multiple platforms and the laying of pipelines, requiring significant manpower and resources and extending the construction period. In addition, the large investment and complex operation and maintenance, with multiple platforms and equipment requiring more manpower and resources for maintenance, increase the company's operating costs. Utility Model Content

[0005] To save space and construction costs for the entire heat accumulator, this application provides an inlet and outlet pipeline system for a spherical heat accumulator that does not require the addition of a platform.

[0006] The inlet and outlet pipeline system for the spherical heat accumulator provided in this application, which eliminates the need for additional platforms, adopts the following technical solution: A platform-free inlet and outlet piping system for a spherical heat accumulator, comprising the spherical heat accumulator body, an inlet steam piping group, an outlet steam piping group, and a central operating platform; The steam inlet pipe group includes two steam inlet pipes, and the steam outlet pipe group includes a steam outlet manifold pipe and two steam outlet pipes. The two steam outlet pipes pass through the central operating platform and then merge with the steam outlet manifold pipe. The steam inlet pipe is connected to the steam inlet of the spherical accumulator body, and the steam outlet pipe is connected to the steam outlet of the spherical accumulator body; the steam inlet pipe group and the steam outlet manifold are respectively connected to the existing steam system platform.

[0007] By adopting the above technical solution, steam enters the spherical accumulator body through two steam inlet pipes of the steam inlet pipe group. After being stored or converted within the spherical accumulator body, the generated steam flows out from the steam outlet through two steam outlet pipes. These two steam outlet pipes pass through the central operating platform and merge with the steam outlet manifold pipe. Finally, the steam outlet manifold pipe connects to the existing steam system platform to complete the steam transportation and distribution. This spherical accumulator avoids reserving space for multiple platforms and equipment, making the entire system layout more compact, reducing the footprint, and the relatively short pipeline path reduces energy loss during steam transportation. At the same time, it reduces the amount of construction work for multiple platforms and pipeline laying, shortening the construction period.

[0008] Optionally, the diameter of the steam inlet pipe is larger than the diameter of the steam outlet pipe.

[0009] By adopting the above technical solution, in the inlet and outlet pipeline system of the spherical accumulator, since the diameter of the steam inlet pipeline is larger than that of the steam outlet pipeline, during the steam flow process, the larger diameter steam inlet pipeline allows the steam to enter the spherical accumulator body at a lower flow rate and smoothly, reducing the impact and resistance when the steam enters, and ensuring that the steam can enter the accumulator smoothly and efficiently; while the smaller diameter steam outlet pipeline can increase the flow rate when the steam flows out, allowing the steam to flow out of the spherical accumulator body quickly and merge into the steam outlet manifold pipeline through the steam outlet pipeline, and then connect to the existing steam system platform; thereby optimizing the flow of steam in the inlet and outlet pipeline system of the spherical accumulator, improving the steam transportation efficiency, and reducing the energy loss during the steam transportation process.

[0010] Optionally, the diameter of the steam inlet pipe is D1, the pipe wall thickness is 14mm, and 350≤D1≤365mm; The diameter of the steam outlet pipe is D2, the wall thickness is 10mm, and 300≤D2≤315mm; The diameter of the steam outlet manifold is D3, the wall thickness is 16mm, and 400≤D3≤410mm.

[0011] By adopting the above technical solutions, the reasonable setting of different pipe diameters and wall thicknesses in the steam inlet pipe, steam outlet pipe, and steam outlet manifold pipe ensures the smooth flow of steam in the pipeline system, reduces energy loss during steam transportation, meets the actual needs of steam transportation at the inlet and outlet of the spherical accumulator, and improves the performance of the entire steam recovery and utilization system.

[0012] Optionally, the steam inlet and steam outlet of the spherical heat accumulator body are both located at the top of the spherical heat accumulator body.

[0013] By adopting the above technical solution, both the steam inlet and the steam outlet are located on the top of the spherical heat accumulator body, which avoids the need to add multiple platforms and reduces the floor space. At the same time, setting the steam inlet and outlet on the top facilitates the smooth entry and exit of steam and optimizes the overall layout of the system.

[0014] Optionally, the steam inlet pipe and the steam outlet pipe are arranged in layers in the vertical direction, with the steam inlet pipe located above the steam outlet pipe.

[0015] By adopting the above technical solution, the steam inlet and outlet pipes are arranged in layers in the vertical direction, making the pipe system structure more compact, avoiding pipe intersections and confusion, and reducing the footprint.

[0016] Optionally, the heat accumulator body is fixed with a ring-shaped ladder from bottom to top.

[0017] By adopting the above technical solution, staff can conveniently inspect and maintain the heat accumulator body via the circular escalator without the need for additional complex climbing equipment, thus improving the convenience and safety of personnel operating the heat accumulator body.

[0018] Optionally, a shut-off valve is provided on the air intake pipe near the spherical heat accumulator body, and the shut-off valve is fixed to the edge of the central operating platform by a bracket.

[0019] By adopting the above technical solution, the shut-off valve can control the steam flow and on / off state of the spherical heat accumulator body according to actual needs. The shut-off valve is fixed to the edge of the central operating platform by a bracket, which makes it convenient for the staff to operate the shut-off valve on the central operating platform.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. This spherical heat accumulator avoids reserving space for multiple platforms and equipment, making the overall system layout more compact, reducing the floor space, and the pipeline path is relatively short, reducing energy loss during steam transportation; at the same time, it reduces the amount of construction work for multiple platforms and pipeline laying, shortening the construction period; 2. In the inlet and outlet piping system of the spherical accumulator, since the diameter of the inlet pipe is larger than that of the outlet pipe, the larger diameter inlet pipe allows steam to enter the spherical accumulator body at a lower and more stable flow rate during steam flow, reducing the impact and resistance when the steam enters, and ensuring that the steam can enter the accumulator smoothly and efficiently. On the other hand, the smaller diameter outlet pipe can increase the flow rate of the steam when it flows out, allowing the steam to flow out of the spherical accumulator body quickly and merge into the outlet manifold pipe through the outlet pipe, and then connect to the existing steam system platform. This optimizes the flow of steam in the inlet and outlet piping system of the spherical accumulator, improves the steam transportation efficiency, and reduces energy loss during the steam transportation process. 3. By placing both the steam inlet and outlet at the top of the spherical accumulator body, the need for multiple platforms can be avoided, reducing the floor space required. At the same time, setting the steam inlet and outlet at the top facilitates the smooth flow of steam and optimizes the overall system layout. The layered arrangement of the steam inlet and outlet pipes in the vertical direction makes the pipe system structure more compact, avoids pipe crossings and confusion, and reduces the floor space required.

[0023] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0024] Currently, there are four 150m³ horizontal heat accumulators, each arranged on a 9.5×9.5m platform. The plant size is 20×32m, and the height is 18.8m. The inlet and outlet of each of the four 150m³ horizontal heat accumulators consists of a 250mm diameter inlet pipe and a 250mm diameter outlet pipe. The steam pipes and supporting valves and other auxiliary facilities are arranged on a 4.4m×13.5 platform. The plant occupies a large area, has long pipeline routes, a large amount of engineering work, a large investment amount, and is complex to operate and maintain.

[0025] In order to achieve the effects of reducing floor space, lowering energy consumption and costs, and simplifying maintenance, the following is a further detailed description of this application.

[0026] This application discloses an inlet and outlet pipeline system for a spherical heat accumulator that eliminates the need for an additional platform. (Refer to...) Figure 1 and Figure 2 The platform-free inlet and outlet pipeline system includes a spherical accumulator body 1, an inlet steam pipeline group 2, an outlet steam pipeline group 3, and a central operating platform 4. The inlet steam pipeline group 2 includes two inlet steam pipelines 21, and the outlet steam pipeline group 3 includes an outlet steam manifold 31 and two outlet steam pipelines 32. The two outlet steam pipelines 32 pass through the central operating platform 4 and merge with the outlet steam manifold 31. The inlet steam pipeline 21 connects to the steam inlet 11 of the spherical accumulator body 1, and the outlet steam pipelines 32 connect to the steam outlet 12 of the spherical accumulator body 1. The inlet steam pipeline group 2 and the outlet steam manifold 31 are respectively connected to the existing steam system platform. Compared to arranging multiple horizontal accumulators on different platforms, using a spherical accumulator body 1 avoids the need for additional platforms, reduces the floor space, and results in a more compact structure. The reasonable connection and merging method of the inlet steam pipeline group 2 and the outlet steam pipeline group 3 makes the pipeline layout more concentrated and reduces the number of pipeline paths.

[0027] Steam enters the spherical accumulator body 1 through the two steam inlet pipes 21 of the steam inlet pipe group 2. After being stored or converted in the spherical accumulator body 1, the generated steam flows out from the steam outlet 12 through the two steam outlet pipes 32. The two steam outlet pipes 32 pass through the central operating platform 4 and merge with the steam outlet manifold pipe 31. Finally, the steam outlet manifold pipe 31 connects to the existing steam system platform to complete the steam transportation and distribution.

[0028] Specifically, refer to Figure 1 and Figure 2 Both the inlet pipe 21 and the outlet pipe 32 are made of carbon steel or stainless steel, possessing good strength and corrosion resistance, and capable of withstanding high temperature and pressure of steam. To ensure uniform steam flow within the pipes and reduce resistance, the inlet pipe 21 and outlet pipe 32 are circular in shape. The two inlet pipes 21 are arranged in parallel to ensure uniform steam entry into the spherical accumulator body 1. The diameter of the inlet pipe 21 is larger than that of the outlet pipe 32. The diameter of the inlet pipe 21 is D1, and the wall thickness is 14mm, with 350≤D1≤365mm. The diameter of the outlet pipe 32 is D2, and the wall thickness is 10mm, with 300≤D2≤315mm. The diameter of the outlet manifold pipe 31 is D3, and the wall thickness is 16mm, with 400≤D3≤410mm. The larger diameter of the outlet manifold pipe 31 than that of the outlet pipe 32 ensures smooth steam delivery after confluence, reducing resistance.

[0029] Specifically, refer to Figure 1 and Figure 2The spherical accumulator body 1 is the core component of the entire system. Its spherical shape makes the internal space of the accumulator more uniform. The steam inlet 11 and steam outlet 12 of the spherical accumulator body 1 are both located at the top, avoiding the need for multiple platforms and reducing the floor space required. The top-mounted steam inlet 11 and outlet also facilitate smooth steam flow and optimize the overall system layout. A circular ladder 5 is fixed to the spherical accumulator body 1 from bottom to top, allowing personnel to easily inspect and maintain the accumulator body without the need for additional complex climbing equipment, thus improving the convenience and safety of personnel operation. The central operating platform 4 is a horizontal platform providing space for operation and maintenance. Two steam outlet pipes 32 pass through the central operating platform 4, where monitoring equipment and control devices can be installed for real-time monitoring and control of steam flow.

[0030] The steam inlet pipe 21 and the steam outlet pipe 32 are arranged vertically in layers, with the steam inlet pipe 21 located above the steam outlet pipe 32. This avoids mutual interference between the pipes, resulting in a more rational pipe layout and facilitating maintenance and repair by personnel. A shut-off valve 6 is installed near the spherical accumulator body 1 on the steam inlet pipe. The shut-off valve 6 is fixed to the edge of the central operating platform 4 by a bracket. The function of the shut-off valve 6 is to control the flow of steam in the steam inlet pipe 21. When maintenance or repair of the spherical accumulator body 1 is required, the shut-off valve 6 can be closed to cut off the steam supply.

[0031] The implementation principle of an inlet and outlet pipeline system for a spherical thermal accumulator without the need for additional platforms, as described in this application, is as follows: This application uses a spherical thermal accumulator body 1, avoiding the need for multiple horizontal thermal accumulators to be arranged on different platforms, thus reducing the floor space and making the overall system layout more compact. Steam enters the spherical thermal accumulator body 1 through two steam inlet pipes 21 of the steam inlet pipe group 2. After storage or conversion within the spherical thermal accumulator body 1, the generated steam flows out from the steam outlet 12 through two steam outlet pipes 32. The two steam outlet pipes 32 pass through the central operating platform 4 and merge with the steam outlet manifold pipe 31, finally connecting to the existing steam system platform via the steam outlet manifold pipe 31 to complete the steam transportation and distribution. The reasonable connection and merging method of the steam inlet pipe group 2 and the steam outlet pipe group 3 shortens the pipeline path and reduces energy loss and construction costs during steam transportation.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
