Description

A segmented skid-mounted combined solid electric thermal storage boiler Technical Field

[0001] This disclosure relates to the field of solid electric thermal energy storage technology, specifically to a solid electric thermal energy storage boiler with a segmented skid-mounted combined structure. Background Technology

[0002] With the increasing number of clean energy optimization and utilization projects, solid-state electric thermal storage equipment has gained a foothold in the thermal energy storage industry due to its high cost-effectiveness, high stability, and reliability, and is widely recognized by users. Traditional solid-state electric thermal storage equipment is mostly integrated equipment, such as the "Combined Structure of a Skid-Mounted Solid-State Electric Thermal Storage Boiler" with application number 202410297718.5, which is a conventional skid-mounted containerized solid-state electric thermal storage boiler. All functional structural facilities are installed in a standard container. However, during sea transportation, there are size and load-bearing requirements for each container loaded on the ship. Generally, the weight of a 40-foot container should not exceed 30.48 tons. A skid-mounted solid-state electric thermal storage boiler with a 40-foot container shell must have a total weight of at least 15 tons for all heat exchange components, insulation, and the container itself. The weight of the solid thermal storage material inside should not exceed 15 tons, and the thermal storage capacity provided to the user should not exceed 4000 kWh. This limits the application range of skid-mounted solid-state electric thermal storage boilers. Therefore, the integrated design of existing solid-state electric thermal storage boilers leads to difficulties in transportation, high transportation costs, and a limited range of applications.

Without further limitation, an element defined by the phrase “comprising…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0071] This embodiment provides a segmented skid-mounted combined solid electric thermal storage boiler, which can be configured in various ways depending on the operating voltage, equipment power, and thermal storage requirements.

[0072] As shown in Figures 1, 2, and 3, this is the first combination method, which is the standard heat storage mode. It mainly includes a heat exchange section box 1, an intermediate section heat storage box 2, and a basic section heat storage box 3. The heat exchange section box 1 has a box flange structure 10 on the high-temperature zone 16 of one side of the heat exchange component 12; the intermediate section heat storage box 2 has box flange structures 10 on both ends; the basic section heat storage box 3 has a box flange structure 10 on one end, and a blind plate on the other side. The blind plate contains an insulation layer 22, and a low-temperature zone 18 exists between the insulation layer 22 and the solid heat storage body. During assembly, the heat exchange section box 1, intermediate section heat storage box 2, and basic section heat storage box 3 are connected sequentially. The connecting box flange structures 10 are filled with connecting seals 9 for sealing and waterproofing, and are secured with fasteners 8 to ensure a safe and reliable connection. Finally, an inter-section insulation structure 7 is used to insulate the connection points. The high-temperature zone 16 and the inter-section connection zone 17 are isolated from the heat storage box return air channel 19 by the insulating partition 11, so that the high and low temperature air paths are separated and mixed air is avoided.

[0073] When the system is in operation, under the action of the circulating fan 13, the high-temperature hot air in the high-temperature zone 16 enters the heat exchange component 12, and the heat energy is released into low-temperature air through the heat exchange component 12. Then, it enters the return air channel 19 of each heat storage box through the return air channel 14, and finally flows into the low-temperature zone 18. The low-temperature air in the low-temperature zone 18 then flows through the solid heat storage body 20 of the basic section heat storage box 3, the inter-section connection area 17, and the solid heat storage body 20 of the intermediate section heat storage box 2 in sequence, and once again forms high-temperature hot air that enters the high-temperature zone 16. The above cycle process is repeated, and finally the heat energy stored in the solid heat storage body 20 of the basic section heat storage box 3 and the solid heat storage body 20 of the intermediate section heat storage box 2 is supplied and output as heat in the required heat medium through the heat exchange component 12.

[0074] The bottom of the heat exchange section box 1, the intermediate section heat storage box 2, the basic section heat storage box 3, the heat storage box A4, the heat storage box B5, and the heat storage box C6 are all provided with thermal insulation foundation 21. The heat exchange component 12 in the heat exchange section box 1 is placed on the thermal insulation foundation 21, and the solid heat storage body 20 in the other heat storage boxes is placed on the thermal insulation foundation 21.

[0075] Intersection connection area 17 serves as both the hot air connection area and the electrical connection area between the intermediate section heat storage box 2 and the basic section heat storage box 3. It can be accessed for construction and maintenance via inspection door 23. Figure 3 shows a schematic diagram of the high-voltage electrical connection. An electrical system consists of three sets of equipment, each set comprising a heat exchange section box 1, an intermediate section heat storage box 2, and a basic section heat storage box 3. The high-voltage electrical components in the intermediate section heat storage box 2 and the basic section heat storage box 3 are connected as shown in Figure 3.

[0076] As shown in Figures 4, 5, 6, and 7, this is the second combination method, which is a small heat storage mode. It mainly includes a heat exchange section box 1 and a basic section heat storage box 3. The heat exchange section box 1 has a box flange structure 10 on the end face of the high-temperature zone 16 on one side of the heat exchange assembly 12. The basic section heat storage box 3 has a box flange structure 10 on one side of its end face, and a low-temperature zone 18 on the other side, with an insulation layer 22 between them. During assembly, the heat exchange section box 1 and the basic section heat storage box 3 are connected. The connecting flange structures 10 are filled with connecting seals 9 to provide a waterproof seal, and are secured with fasteners 8 to ensure a safe and reliable connection. Finally, an inter-section insulation structure 7 is used to insulate the connection points. The high-temperature zone 16 is isolated from the heat storage box return air channel 19 by an insulating partition 11, separating the high and low temperature air paths and preventing air mixing.

[0077] When the system is in operation, under the action of the circulating fan 13, the high-temperature hot air in the high-temperature zone 16 enters the heat exchange component 12, and the heat energy is released into low-temperature air through the heat exchange component 12. Then, it enters the return air channel 19 of the heat storage box through the return air channel 14, and finally flows into the low-temperature zone 18. The low-temperature air in the low-temperature zone 18 flows through the solid heat storage body 20 of the basic section heat storage box 3, and forms high-temperature hot air again to enter the high-temperature zone 16. The above cycle process is repeated, and finally the heat energy stored in the solid heat storage body 20 of the basic section heat storage box 3 is output as the required heat medium through the heat exchange component 12. Figure 6 shows a schematic diagram of high-voltage electrical connection. An electrical system consists of three sets of equipment. Each set of equipment consists of two types of enclosures: heat exchange section enclosure 1 and basic section heat storage enclosure 3. The high-voltage electrical components in the basic section heat storage enclosure 3 are connected as shown in Figure 3. Figure 7 shows a schematic diagram of low-power, low-voltage electrical connection. An electrical system consists of one set of equipment. The equipment consists of two types of enclosures: heat exchange section enclosure 1 and basic section heat storage enclosure 3. The low-voltage electrical components in the basic section heat storage enclosure 3 are connected as shown in Figure 7.

[0078] As shown in Figures 8, 9, and 10, this is combination mode three, which is a high-power, high-heat-storage mode. It mainly includes a heat exchange section box 1, multiple intermediate section heat storage boxes 2, and a basic section heat storage box 3. The heat exchange section box 1 has a box flange structure 10 on the end face of the high-temperature zone 16 on one side of the heat exchange assembly 12; both end faces of the intermediate section heat storage boxes 2 have box flange structures 10; one end face of the basic section heat storage box 3 has a box flange structure 10, and the other side is a low-temperature zone 18, with an insulation layer 22 between it and the box.

[0079] During assembly, the heat exchange section box 1, multiple intermediate section heat storage boxes 2, and the basic section heat storage box 3 are connected sequentially. The flange structures 10 of the interconnected boxes are filled with sealing seals 9 to provide waterproofing, and are secured with fasteners 8 to ensure a safe and reliable connection. Finally, the joints are insulated using inter-section insulation structures 7. The high-temperature zone 16 and the inter-section connection zone 17 are isolated from the heat storage box return air channel 19 by insulating partitions 11, separating the high and low temperature air paths and preventing air mixing.

[0080] When the system is in operation, under the action of the circulating fan 13, the high-temperature hot air in the high-temperature zone 16 enters the heat exchange component 12, and the heat energy is released into low-temperature air through the heat exchange component 12. Then, it enters the return air channel 19 of each heat storage box through the return air channel 14, and finally flows into the low-temperature zone 18. The low-temperature air in the low-temperature zone 18 then flows through the solid heat storage body 20 of the basic section heat storage box 3, the connecting area 17 between each section and the solid heat storage body 20 of the intermediate section heat storage box 2 in sequence, and once again forms high-temperature hot air to enter the high-temperature zone 16. The above cycle process is repeated, and finally the heat energy stored in the solid heat storage body 20 of the basic section heat storage box 3 and the solid heat storage body 20 of the intermediate section heat storage box 2 is supplied and output as heat in the required heat medium through the heat exchange component 12. Figure 10 shows a schematic diagram of high-voltage electrical connection. An electrical system consists of three sets of equipment. Each set of equipment consists of three types of boxes: heat exchange section box 1, multiple intermediate section heat storage boxes 2, and basic section heat storage box 3. The high-voltage electrical components in the intermediate section heat storage box 2 and the basic section heat storage box 3 are connected in the manner shown in Figure 10.

[0081] As shown in Figures 11, 12, and 13, this is combination mode four, which is a high-voltage, low-heat-storage mode. It mainly includes a heat exchange section box 1, a heat storage box A4, a heat storage box B5, and a heat storage box C6. The heat exchange section box 1 has a box flange structure 10 on the end face of the high-temperature zone 16 on one side of the heat exchange assembly 12; both end faces of the heat storage boxes A4 and B5 have box flange structures 10; one end face of the heat storage box C6 has a box flange structure 10, and the other side is a low-temperature zone 18, with an insulation layer 22 between it and the box.

[0082] During assembly, the heat exchange section box 1, heat storage box A4, heat storage box B5, and heat storage box C6 are connected sequentially. The flange structures 10 of the interconnecting boxes are filled with sealing seals 9 to provide waterproofing, and are secured with fasteners 8 to ensure a safe and reliable connection. Finally, the joints are insulated using inter-section insulation structures 7. The high-temperature zone 16 and the inter-section connection zone 17 are isolated from the heat storage box return air channel 19 by insulating partitions 11, separating the high and low temperature air paths and preventing air mixing.

[0083] When the system is in operation, under the action of the circulating fan 13, the high-temperature hot air in the high-temperature zone 16 enters the heat exchange component 12, where the heat energy is released as low-temperature air through heat exchange component 12. The air then enters the return air channel 19 of each heat storage box through the return air channel 14, and finally flows into the low-temperature zone 18. The low-temperature air in the low-temperature zone 18 then flows sequentially through the solid heat storage body 20 of heat storage box C6, the inter-section connection area 17, the solid heat storage body 20 of heat storage box B5, the inter-section connection area 17, and the solid heat storage body 20 of heat storage box A4, forming high-temperature hot air again entering the high-temperature zone 16. This cycle is repeated, and finally the heat energy stored in the solid heat storage body 20 of heat storage box C6, the solid heat storage body 20 of heat storage box B5, and the solid heat storage body 20 of heat storage box A4 is supplied as heat through the heat exchange component 12 in the form of the required heat medium.
