Description

Technical Field

[0001] The invention relates to the technical field of skid-mounted structures of solid electric heat storage furnaces, and in particular to a modular container based on a skid-mounted solid electric heat storage furnace and an installation method thereof. Background Art

[0002] At present, skid-mounted solid electric thermal storage furnace equipment basically adopts standard container structure as the equipment shell. The container is produced by the container manufacturer in accordance with the standard, and the solid electric thermal storage furnace manufacturer performs subsequent assembly and production in the standard container. Since the standard container is an integrated structure that has been welded, its internal space is fixed and narrow. Because the electric thermal storage furnace equipment includes a large number of masonry thermal storage brick materials, the installation of heat exchange system equipment, etc., as well as the insulation structure around and on the top, the process flows affect each other and cannot be constructed synchronously. Therefore, it is extremely inconvenient for the production and assembly of the solid electric thermal storage furnace, which reduces production efficiency and affects product quality. Summary of the invention

[0003] In view of the above technical requirements, the purpose of the present invention is to provide a modular container based on a skid-mounted solid electric heat storage furnace and an installation method thereof, aiming to solve the problem that when the skid-mounted solid electric heat storage furnace equipment uses a standard container as the outer shell, the operating space is small, which affects the production efficiency and production quality.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, a modular container based on a skid-mounted solid electric heat storage furnace comprises: The load-bearing base is a metal platform structure with connecting columns on the platform; The box body is connected one by one by load-bearing steel columns, steel beams at the bottom of the box body, steel beams at the top of the box body and external protective iron plates to form a box body structure with a hollow bottom, which is covered on the load-bearing base, and the load-bearing steel columns are inserted into the outside of the connecting columns and fixed with screws; The thermal insulation felt layer is made of aluminum silicate fiber cotton and is attached to the inner surface of the box, with a hollow bottom; The insulation brick layer is a plane structure built with insulation bricks to block the heat of the solid heat storage body. The insulation brick layer is arranged on a load-bearing base and fixed. The insulation brick layer is connected to the insulation felt layer to enclose and form an insulation cavity. The solid heat storage body is a geometric body with heat storage and heat release capabilities built by refractory blocks and placed in the insulation cavity; The heat exchange component is a device that can absorb the heat of the solid heat storage body and output hot water, steam, heat transfer oil and hot air. It is arranged on a load-bearing base and fixed.

[0005] Furthermore, a plurality of the load-bearing steel columns are provided, each of which is provided with a through hole for a fastening bolt, and a fastening nut is welded corresponding to the through hole position on the inner side of the load-bearing steel column facing the inside of the box body.

[0006] Furthermore, the load-bearing base is provided with 4, 6 or 8 connecting columns, each connecting column is provided with a column bolt through hole, and is screwed and fixed to the load-bearing steel column by a fastening bolt.

[0007] Furthermore, the load-bearing base includes a main steel beam of the base, a load-bearing steel plate of the base, connecting columns and base reinforcement ribs. The load-bearing steel plate of the base is laid on the main steel beam of the base, the connecting columns are arranged at intervals at the edge of the load-bearing steel plate of the base, and base reinforcement ribs are welded at intervals on the outer circle of the main steel beam of the base.

[0008] Furthermore, a closed weld is provided at the connection between the box body and the outer surface of the load-bearing base.

[0009] Furthermore, the heat exchange component includes a shell and tube heat exchanger and a fan, and the shell and tube heat exchanger is connected to the fan to form a drive circuit.

[0010] In a second aspect, a method for installing a modular container based on a skid-mounted solid electric heat storage furnace comprises: The load-bearing steel columns, the bottom steel beams of the box, the upper steel beams of the box and the external protective iron plates are connected one by one to form a box with a hollow bottom. A thermal insulation felt layer is attached to the inner surface of the box, and then a thermal insulation brick layer is laid on the load-bearing base. The positions of the thermal insulation brick layer and the thermal insulation felt layer are kept consistent in the vertical direction. A solid heat storage body is placed on the thermal insulation brick layer, and a heat exchange component is placed on the load-bearing base. Then, the box with the thermal insulation felt layer is covered on the load-bearing base, and the load-bearing steel columns are connected to the connecting columns by bolting. The connection between the outside of the box and the load-bearing base is welded by welding to form a closed weld, thus completing the connection between the external components. During disassembly, the connection between the load-bearing steel column and the connecting column is released by removing the bolts, and the welded structure between the outside of the box and the load-bearing base is decomposed through the welding points; since there is only a closed weld on the outside and no weld inside the connection, the closed weld can be directly cut open to separate the box with the hollow bottom and the load-bearing base. The technical solution adopted by the present invention has the following advantages: The container is divided into two parts: a box body and a load-bearing base. The corresponding materials, equipment and components of the solid electric heat storage furnace are installed and produced on the box body and the load-bearing base, and finally assembled into one and transported to the site for installation. When installing the solid electric heat storage furnace, the connection between the load-bearing steel column and the connecting column can be released by removing the bolts, and the welding structure between the outside of the box body and the load-bearing base can be decomposed through the welding points. Since the parts of the box body with the insulation felt layer and the parts of the load-bearing base with the insulation brick layer only have closed welds on the outside and no welds on the inside, the closed welds can be directly cut open to separate the box body with the hollow bottom and the load-bearing base. This can free up space for installing the solid electric heat storage furnace, provide sufficient production operation space, improve installation efficiency by 5-8 times, greatly shorten installation time, and ensure product quality.

[0014] In this embodiment, a modular container based on a skid-mounted solid electric heat storage furnace, such as Figure 1-Figure 8 As shown; Figure 3 is a schematic diagram of the side structure of the box 1, Figure 4 It is a schematic diagram of the structure of the box body 1 when viewed from above. The box body 1 is a hollow box body with 4, 6 or 8 load-bearing steel columns 1-1, a steel beam 1-2 at the bottom of the box body and a steel beam 1-3 at the top of the box body as the main structure, and the outside and the top are covered with an external protective iron plate 1-4. A fastening bolt through hole 1-1-1 is provided on each load-bearing steel column 1-1, and a fastening nut 1-1-2 is welded corresponding to the fastening bolt through hole 1-1-1 on the inner side of the load-bearing steel column 1-1.

[0015] Figure 5 is a side view of the structure of the load-bearing base 2, Figure 6It is a top view structural diagram of the load-bearing base 2, which is composed of a base main steel beam 2-1 and a base load-bearing steel plate 2-2, wherein a base reinforcement rib 2-4 is welded to the base main steel beam 2-1 to increase the load-bearing strength of the load-bearing base 2, and 4, 6 or 8 connecting columns 2-3 are welded to the load-bearing base 2, and each connecting column 2-3 is provided with a column bolt through hole 2-3-1.

[0016] Figure 1 It is a schematic diagram of the main structure after assembly. After the previous installation work is completed, the upper box body 1 is placed on the base 2. 12 or 16 (depending on the design, 4, 6 or 8 main load-bearing steel columns) fastening bolts 4 with a certain tensile strength and yield strength pass through the fastening bolt through holes 1-1-1 and the corresponding column bolt through holes 2-3-1, and are fastened to the fastening nuts 1-1-2. The main load-bearing steel column 1-1 is inserted on the outside of the connecting column 2-3. At the same time, the box bottom steel beam 1-2 of the box body 1 is fully welded with the main steel beam 2-1 of the base of the load-bearing base 2 to form a closed weld 3 to ensure structural strength and waterproof functions, and finally complete the entire assembly work of the skid-mounted electric heat storage furnace.

[0017] This embodiment provides a method for installing a split structure of a skid-mounted solid electric heat storage furnace. The container manufacturer produces Figure 3 The box 1 and Figure 5 The two parts of the load-bearing base 2 shown are separated when the electric heat storage furnace equipment is assembled. Figure 7 As shown, a thermal insulation felt layer 5 and other auxiliary accessories are installed at a designated position on the inner surface of the box body 1; Figure 8 As shown, the insulation brick layer 6, the solid heat storage body 7 and the heat exchange component 8 (depending on the specific design, sometimes there is only one material or component), as well as other auxiliary accessories, are installed at the designated position of the load-bearing base 2. The heat exchange component 8 is composed of a shell and tube heat exchanger 9, a fan 10 and various accessories. After the components that can be separated and assembled are assembled, the box body 1 is hoisted and combined with the load-bearing base 2 for structure. 12 or 16 (depending on the design of 4, 6 or 8 main load-bearing steel columns) high-strength fastening bolts 4 with certain tensile strength and yield strength pass through the fastening bolt through hole 1-1-1 and the corresponding column bolt through hole 2-3-1, and are fastened to the fastening nut 1-1-2. The load-bearing steel column 1-1 is inserted into the outside of the connecting column 2-3. At the same time, the bottom steel beam 1-2 of the box body 1 and the main steel beam 2-1 of the base of the load-bearing base 2 are fully welded to form a closed weld 3 to ensure the structural strength and waterproof functions, and finally complete the assembly of the skid-mounted electric heat storage furnace.

[0018] In an embodiment of the present invention, the solid heat storage body 7 is fixed to the insulating brick layer 6 below, the insulating brick layer 6 and the base load-bearing steel plate 2-2 on the load-bearing base 2 are fixed; and the heat exchange component 8 and the base load-bearing steel plate 2-2 on the load-bearing base 2 are also fixed; the above-mentioned fixed structures are all directly installed and fixed at the manufacturer without the need to change their position. After being transported to the construction site, they can be directly connected to the heating pipeline of the heating manufacturer, which can greatly save the time of on-site installation implementation.

[0019] When disassembling, the connection between the load-bearing steel column 1-1 and the connecting column is released by removing the bolts, and the welding structure between the outside of the box body 1 and the load-bearing base 2 is decomposed through the welding points; since the part of the box body 1 with the insulation felt layer 5 and the part of the load-bearing base 2 with the insulation brick layer 6 only have the closed weld 3 on the outside and no weld inside, the closed weld 3 can be directly cut open to separate the box body 1 with the hollow bottom and the load-bearing base 2; after the box body 1 and the load-bearing base 2 are separated, the solid electric heat storage furnace can be assembled in an open space, avoiding the problems of small space and inconvenient operation in the previous container, providing sufficient production and operation space for the assembly of the solid electric heat storage furnace, and improving production efficiency. In the past, it took at least 5-6 days to install the equipment, but through the improvement of the structure and installation method of the present invention, the overall installation of the equipment can be basically completed within half a day to a day, and the quality of the product can be guaranteed.

[0020] When a large number of repairs are required on the interior of the electric heat storage furnace, since the technical solution only has closed welds 3 on the outside of the part of the box 1 with the insulation felt layer 5 and the part of the load-bearing base 2 with the insulation brick layer 6 and no welds on the inside, the closed welds 3 can be directly cut open to separate the box 1 and the load-bearing base 2, which is convenient for construction operations.

[0021] In an embodiment of the present invention, the load-bearing base 2 with the insulation brick layer 6, the solid heat storage body 7 and the heat exchange component 8 and the bottom hollow box 1 with the insulation felt layer 5 have the ability to be combined and decomposed, that is: the outer surface of the bottom hollow box 1 with the insulation layer and the outer surface of the load-bearing base 2 with the insulation brick layer can be connected by bolting, riveting or welding, or the connection structure can be decomposed by removing the connection points by bolting, riveting or welding.

[0022] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
