Description

Technical Field

[0001] This utility model relates to the field of gas transportation technology, specifically a dedicated gas transportation pipeline that effectively reduces energy consumption. Background Technology

[0002] In industrial production and urban gas supply, pipeline gas transportation is a common energy supply method. During long-distance transportation, energy loss mainly comes from two aspects: First, pressure energy loss caused by frictional resistance between the gas and the inner wall of the pipeline. To maintain the terminal pressure, it is necessary to increase the boosting frequency and power of the pump station, resulting in wasted electricity. Second, heat loss due to temperature difference between the inside and outside of the pipeline. In particular, when transporting high-temperature steam or process gases that need to be maintained at a specific temperature, heat loss is particularly significant, increasing additional heating costs.

[0003] Existing pipelines, although they use simple insulation layers, have limited insulation effects and cannot solve the problem of fluid resistance, resulting in significant energy consumption. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dedicated gas supply pipeline for effectively reducing energy consumption, comprising: Pipeline body, including gas transmission pipelines; The energy-saving mechanism includes a spiral guide rib, a low surface energy coating, and a reflective layer. The spiral guide rib is fixedly connected to the inner surface of the gas transmission pipeline. The low surface energy coating is applied to the inner surface of the gas transmission pipeline. The reflective layer is wrapped around the outer surface of the gas transmission pipeline. The outer surface of the reflective layer is wrapped with a microporous heat insulation material layer.

[0006] Preferably, the protective mechanism includes a buffer layer wrapped around the outer surface of a microporous thermal insulation material layer, a moisture-proof layer wrapped around the outer surface of the buffer layer, an outer protective layer wrapped around the outer surface of the moisture-proof layer, a handle fixedly connected to the outer surface of the outer protective layer, a mounting block fixedly connected to the outer surface of the outer protective layer, a mounting bolt penetrating the surface of the mounting block, and a mounting nut threadedly connected to the surface of the mounting bolt.

[0013] The outer surface of the microporous insulation material layer is wrapped with a buffer layer, the outer surface of the buffer layer is wrapped with a moisture-proof layer, and the outer surface of the moisture-proof layer is wrapped with an outer protective layer. The outer protective layer is fixedly connected to the handle, the outer protective layer is fixedly connected to the mounting block, the mounting block is connected to the mounting bolt, and the mounting bolt is connected to the mounting nut. The buffer layer, moisture-proof layer, and outer protective layer are wrapped around the outside of the reflective layer and the microporous insulation material layer, which can protect the reflective layer and the microporous insulation material layer from damage and affect their thermal insulation effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 One embodiment provided by this utility model: A dedicated gas supply pipeline that effectively reduces energy consumption and loss includes: The pipe body includes a gas pipeline 1, which is used to transport gas. The energy-saving mechanism includes a spiral guide rib 2, a low surface energy coating 21, and a reflective layer 22. The spiral guide rib 2 is fixedly connected to the inner surface of the gas pipeline 1. The spiral guide rib 2 converts part of the axial kinetic energy of the gas into rotational kinetic energy, forming a vortex structure with higher pressure in the central region and a reduced velocity gradient near the wall. This effectively suppresses turbulence development, significantly reduces frictional resistance along the flow path, and effectively guides gas flow, thereby reducing the pressurization energy consumed to overcome resistance. The low surface energy coating 21 is applied to the inner surface of the gas pipeline 1. The low surface energy coating 21 reduces the adsorption and friction between gas molecules and the pipe wall, further... To further reduce flow resistance, a reflective layer 22 is wrapped around the outer surface of the gas pipeline 1. The reflective layer 22 is made of aluminum foil or a metallized polymer film. The reflective layer 22 is used to reflect radiant heat and block radiative heat transfer. The outer surface of the reflective layer 22 is wrapped with a microporous heat insulation material layer 23. The microporous heat insulation material layer 23 is made of aerogel felt or nanoporous heat insulation board. It uses its extremely low thermal conductivity to isolate heat conduction. The microporous heat insulation material layer 23 is used to suppress convective heat transfer and heat conduction. The reflective layer 22 and the microporous heat insulation material layer 23 work together to form a highly efficient heat insulation system, which greatly reduces the heat loss of gas during transportation and thus reduces energy consumption.

[0018] Furthermore, the protective mechanism includes a buffer layer 3, which wraps around the outer surface of the microporous insulation material layer 23. The buffer layer 3 is used to relieve external pressure and protect the reflective layer 22 and the microporous insulation material layer 23. The buffer layer 3 can be made of rubber or foam material. The outer surface of the buffer layer 3 is covered with a moisture-proof layer 31. The moisture-proof layer 31 is used to prevent moisture from penetrating the reflective layer 22 and the microporous insulation material layer 23 and reducing the thermal insulation performance, ensuring that the reflective layer 22 and the microporous insulation material layer 23 remain dry for a long time, thus stabilizing the thermal insulation performance of the reflective layer 22 and the microporous insulation material layer 23. The moisture-proof layer 31 can be made of aluminum foil, a specific waterproof roll material, or a waterproof cloth. The outer protective layer 32 is used to resist external environmental erosion and mechanical damage. The outer protective layer 32 can be made of fiberglass or high-performance plastic. A handle 33 is fixedly connected to the outer surface of the outer protective layer 32 to facilitate the installation and removal of the outer protective layer 32. An installation block 34 is fixedly connected to the outer surface of the outer protective layer 32. An installation bolt 35 is connected through the surface of the installation block 34. An installation nut 36 is threaded on the surface of the installation bolt 35. The installation block 34, installation bolt 35 and installation nut 36 are used to facilitate the quick installation and removal of the outer protective layer 32 by the staff, thereby realizing the convenient installation and maintenance of the insulation structure and protection mechanism.

[0019] Furthermore, the spiral guide ribs 2 are evenly distributed in three groups on the inner surface of the gas transmission pipe 1. The cross-section of the spiral guide ribs 2 is streamlined. The spiral guide ribs 2 extend along the axial direction of the gas transmission pipe 1. The spiral guide ribs 2 are used to convert part of the axial kinetic energy of the gas into rotational kinetic energy, forming a vortex structure with higher pressure in the central region and reduced velocity gradient near the wall. This effectively suppresses the development of turbulence, significantly reduces frictional resistance along the flow path, and effectively guides the gas flow, thereby reducing the pressurization energy consumption required to overcome resistance.

[0020] Furthermore, a low surface energy coating 21 is applied to the entire inner surface of the gas pipeline 1. The low surface energy coating 21 is used to reduce the adsorption and friction between gas molecules and the pipe wall, further reducing flow resistance. The reflective layer 22 is an aluminum foil or a metallized polymer film. The reflective layer 22 is used to reflect radiant heat and block radiative heat transfer. The microporous insulation material layer 23 is an aerogel felt or a nanoporous insulation board. It uses its extremely low thermal conductivity to isolate heat conduction. The microporous insulation material layer 23 is used to suppress convective heat transfer and heat conduction. The reflective layer 22 and the microporous insulation material layer 23 work together to form a highly efficient insulation system, which greatly reduces the heat loss of gas during transportation, thereby reducing energy consumption.

[0021] Furthermore, the buffer layer 3 is used to relieve external pressure and protect the reflective layer 22 and the microporous thermal insulation material layer 23. The buffer layer 3 can be made of rubber or foam material. The moisture-proof layer 31 is used to prevent water vapor from penetrating the reflective layer 22 and the microporous thermal insulation material layer 23 and reducing the thermal insulation performance, ensuring that the reflective layer 22 and the microporous thermal insulation material layer 23 are dry for a long time, so that the thermal insulation performance of the reflective layer 22 and the microporous thermal insulation material layer 23 is stable. The moisture-proof layer 31 can be made of aluminum foil, a specific waterproof roll material or waterproof cloth. The outer protective layer 32 is symmetrically distributed in two sets on the outer surface of the moisture-proof layer 31, and the outer protective layer 32 and the moisture-proof layer 31 are movably connected.

[0022] Furthermore, the two sets of outer protective layers 32 are connected together by mounting blocks 34, mounting bolts 35 and mounting nuts 36. The outer protective layer 32 is used to resist external environmental erosion and mechanical damage. The outer protective layer 32 can be made of fiberglass or high-performance plastic.

[0023] Furthermore, the handle 33 is used to facilitate the disassembly and assembly of the outer protective layer 32. The mounting bolt 35 passes through the two sets of mounting blocks 34. The mounting nut 36 is connected to the mounting block 34 by the mounting bolt 35. The mounting block 34, mounting bolt 35 and mounting nut 36 are used to facilitate the quick disassembly and assembly of the outer protective layer 32 by the staff, thereby realizing the convenient installation and maintenance of the insulation structure and protection mechanism.

[0024] Working principle: The spiral guide ribs 2 and the low surface energy coating 21 can reduce the friction between the gas and the pipe wall, and reduce the frictional resistance along the way, thereby reducing the pressurization energy consumed to overcome the resistance. At the same time, the reflective layer 22 can block radiative heat transfer, and the microporous heat insulation material layer 23 can suppress convective heat transfer and heat conduction. The two work together to form a highly efficient heat insulation system, which greatly reduces the heat loss of the gas during the transportation process, thereby reducing energy consumption.

[0025] The buffer layer 3, the moisture-proof layer 31, and the outer protective layer 32 are wrapped around the reflective layer 22 and the microporous thermal insulation material layer 23, which can protect the reflective layer 22 and the microporous thermal insulation material layer 23 and prevent them from being damaged, thus affecting their thermal insulation effect. At the same time, the mounting block 34, the mounting bolt 35, and the mounting nut 36 facilitate the quick installation and removal of the outer protective layer 32 by the staff, thereby realizing the convenient installation and maintenance of the thermal insulation structure and the protective mechanism.
