Description

Technical Field

[0001] This invention relates to the field of waste heat treatment, and more particularly to an integrated device for a SOEC high-temperature electrolysis system driven by multiple waste heat sources. Background Technology

[0002] Waste heat is excess heat generated during industrial production, energy conversion, and equipment operation to achieve the main function but which is not effectively utilized and is ultimately lost to the environment. It is mostly released in the form of convection, radiation, and conduction, and is commonly seen in engine exhaust, boiler waste heat, and electronic device heat dissipation. It is a low-grade energy source, and recycling it can improve energy utilization efficiency and reduce energy waste and environmental thermal pollution.

[0003] In existing technology, waste heat is transferred to the SOEC electrolysis unit through pipelines to provide the heat energy required for the SOEC electrolysis reaction. However, waste heat usually contains a large amount of dust, waste gas and other dirt. When this dirt enters the pipeline and remains, it causes scale to form inside the pipeline. If it is not cleaned in time, it will cause the pipeline to be blocked and the heat transfer effect will be poor. Therefore, operators need to frequently disassemble the pipeline for cleaning. However, during the disassembly and cleaning process, the unit needs to be stopped. The unit will only continue to operate after the pipeline is replaced or cleaned. Therefore, the unit will suffer from reduced working efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: An integrated device for a multi-source waste heat driven SOEC high-temperature electrolysis system includes: a platform, a heat conduction mechanism, and an electrolysis transfer mechanism. The heat conduction mechanism, located above the platform, includes a housing. Each of the inner walls on both sides and the upper inner wall of the housing has a heat transfer hole (a spare upper heat transfer hole, a left heat outlet, and a right heat inlet). A sealing assembly is located inside the housing. This sealing assembly includes a sealing plate, the inner wall of which has a heat transfer hole (corresponding to the spare upper heat transfer hole). Two slide rails (two sliding rails) are located inside the housing and are positioned on the sealing plate. At the bottom of the first type, the interior of the outer shell is provided with several telescopic components. The driving end of each telescopic component is provided with a sliding block. The sliding block is slidably disposed inside the second type of slide rail. The exterior of the sliding block is provided with a vertical plate. The exterior of the vertical plate is provided with several inserts. A ventilation hole is provided between two inserts. The interior of the outer shell is provided with a second type of sealing plate. The inner wall of the second type of sealing plate is provided with four heat transfer holes corresponding to the number of inserts. The inserts and the four heat transfer holes are engaged with each other. An electrolytic transfer mechanism is provided above the vehicle board. The electrolytic transfer mechanism includes an electrolytic device. A heat transfer component is provided outside the electrolytic device.

[0005] As a further description of the above technical solution: The interior of the housing is provided with a first filter assembly, and the exterior of the housing, which is opened on the inner wall above the housing, is provided with a second filter assembly. The sealing plate is disposed inside the housing and located below one of the second filter assemblies. The telescopic member is fixed to the first filter assembly.

[0006] As a further description of the above technical solution: The first filter assembly includes several filter plates 2, which are slidably disposed on the inner wall of the sealing plate 1 and the outer shell. A partition plate is provided on one side of each filter plate 2, which is slidably disposed on the inner wall of the sealing plate 1 and the outer shell. A heat transfer hole 3 is provided on the inner wall of the partition plate, and the telescopic member is fixed to the partition plate.

[0007] As a further description of the above technical solution: The second filter assembly includes two slide rails, which are disposed inside the housing and fixed by bolts. A filter plate is slidably disposed on the inner wall of the slide rail, and the holes of the filter plate are smaller than the holes of the filter plate.

[0008] As a further description of the above technical solution: The heat conduction mechanism also includes an opening and closing assembly, which includes a closing cover. The closing cover is disposed on the outside of the outer shell, and a plurality of closing plates are provided through the closing cover and the inner wall of the outer shell.

[0009] As a further description of the above technical solution: The heat conduction mechanism also includes two slots, which are formed on the inner wall of the closed cover. The filter plate is slidably inserted through the slots. The inner wall of the closed cover has slots two in number equal to the number of filter plates two. The filter plates two are inserted through the slots two.

[0010] As a further description of the above technical solution: The heat conduction mechanism also includes a heat inlet pipe, which is located outside the right heat inlet hole and is positioned at the same horizontal level as one of the second filter components. A spare heat outlet pipe is located outside the upper spare heat transfer hole. The spare heat outlet pipe is located outside the outer casing. A main heat outlet pipe is located on the side of the outer casing away from the heat inlet pipe, and the main heat outlet pipe corresponds to the left heat outlet hole.

[0011] As a further description of the above technical solution: The heat transfer assembly includes a heat pipe, which is disposed at the output port of the outer shell. A control valve is disposed outside the heat pipe, and the backup heat pipe and the main heat pipe are fixedly connected to the heat pipe.

[0012] As a further description of the above technical solution: The vehicle platform also includes two sets of casters, which are located at the bottom of the vehicle platform.

[0013] The present invention has the following beneficial effects: 1. In this invention, waste heat gas enters the right heat inlet of the outer shell through the heat inlet pipe. Under normal conditions, the telescopic component drives the sliding block to slide within the slide rail two, causing the vertical plate and the insert block to insert into the heat transfer hole four of the sealing plate two. The heat transfer hole two of the sealing plate one is offset from the upper spare heat transfer hole of the outer shell. The waste heat gas enters the electrolysis transmission mechanism through the left heat outlet, the main heat outlet pipe, and the heat conduction pipe. If the inside of the main heat outlet pipe needs to be cleaned, the backup circuit can be activated: the telescopic component is controlled to drive the insert block to disengage from the heat transfer hole four, so that the heat transfer hole two of the sealing plate one is aligned with the upper spare heat transfer hole. The waste heat gas is then transported to other electrolysis devices through the upper spare heat transfer hole, the spare heat outlet pipe, and the heat conduction pipe. This structure achieves the effect of multiple waste heat transmission paths and no downtime during maintenance. It solves the problem in the prior art where operators frequently disassemble the pipes for cleaning, but the device needs to be stopped during disassembly and cleaning, and will only continue to operate after the pipes are replaced or cleaned, thus reducing the device's working efficiency.

[0014] 2. In this invention, the first filter assembly includes several filter plates (secondary filters). In the second filter assembly, a slide rail (first slide rail) is fixed inside the outer casing by bolts. Filter plates (secondary filters) slide within the slide rail, and their apertures are smaller than those of filter plates (secondary filters). This allows for secondary fine filtration of the gas passing through the first filter assembly. Slots (secondary filters) on the inner wall of the sealed cover allow filter plates (secondary filters) to slide through. The number of slots (secondary filters) corresponds to the number of filter plates (secondary filters). This structure achieves multi-stage filtration and rapid filter plate installation, solving the problems of long installation and disassembly times and prolonged downtime due to incomplete filtration in existing waste heat filtration technologies.

[0017] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0018] Reference Figures 1 to 4 This invention provides an embodiment of a multi-source waste heat driven SOEC high-temperature electrolysis system integrated device, comprising: a platform 10, a heat conduction mechanism 20, and an electrolysis transmission mechanism 30. The heat conduction mechanism 20, located above the platform 10, includes a housing 21. Heat transfer holes 22 are provided on the inner walls of both sides and the upper inner wall of the housing 21. The heat transfer holes 22 are an upper spare heat transfer hole, a left heat outlet, and a right heat inlet. A sealing assembly is provided inside the housing 21, including a sealing plate 23. Heat transfer holes 24 are provided on the inner wall of the sealing plate 23, corresponding to the upper spare heat transfer holes. Two slide rails 217 are provided inside the housing 21, positioned on the sealing plate 23. At the bottom, the interior of the outer shell 21 is provided with several telescopic members 213. The driving end of the telescopic member 213 is provided with a sliding block 214. The sliding block 214 is slidably disposed inside the slide rail 217. The exterior of the sliding block 214 is provided with a vertical plate 215. The exterior of the vertical plate 215 is provided with several inserts 216. A ventilation hole is provided between two inserts 216. The interior of the outer shell 21 is provided with a sealing plate 218. The inner wall of the sealing plate 218 is provided with heat transfer holes 219 corresponding to the number of inserts 216. The inserts 216 and the heat transfer holes 219 are engaged with each other. An electrolytic transfer mechanism 30 is provided above the vehicle plate 10. The electrolytic transfer mechanism 30 includes an electrolytic device 31. A heat transfer component is provided on the exterior of the electrolytic device 31. In the above embodiment, when the device is running, waste heat gas enters the right heat inlet of the outer shell 21 through the heat inlet pipe 220. Under normal conditions, the telescopic component 213 drives the sliding block 214 to slide within the slide rail 217, causing the vertical plate 215 and the insert block 216 to insert into the heat transfer hole 219 of the sealing plate 218. The heat transfer hole 24 of the sealing plate 23 is offset from the upper spare heat transfer hole of the outer shell 21. The waste heat gas enters the electrolysis transmission mechanism 30 through the left heat outlet, the main heat outlet pipe 222, and the heat conduction pipe 32. If the inside of the main heat outlet pipe 222 needs to be cleaned, the backup circuit can be activated: the telescopic component 213 is controlled to drive the insert block 216 to disengage from the heat transfer hole 219, so that the heat transfer hole 24 of the sealing plate 23 is aligned with the upper spare heat transfer hole. The waste heat gas is then transported to other electrolysis devices 31 through the upper spare heat transfer hole, the spare heat outlet pipe 221, and the heat conduction pipe 32, achieving the effect of not stopping the machine during maintenance and improving the transmission efficiency of the device.

[0019] The interior of the outer casing 21 is provided with a first filter assembly, and the outer casing 21 and the outer casing 21 with openings on the inner wall above the outer casing 21 are provided with second filter assemblies. The sealing plate 23 is provided inside the outer casing 21 and located below one of the second filter assemblies. The telescopic member 213 is fixed to the first filter assembly. In the above embodiment, the first filter assembly inside the outer casing 21 is responsible for the initial purification of waste heat gas, while the second filter assembly on the outer casing 21 and its upper inner wall performs secondary fine filtration. The sealing plate 23 is disposed below one of the second filter assemblies to guide the airflow; the telescopic member 213 is fixed to the first filter assembly, providing power for the linkage adjustment of the filter assembly and ensuring that the waste heat gas is continuously purified during transmission.

[0020] The first filter assembly includes several filter plates 210. The filter plates 210 are slidably disposed on the inner wall of the sealing plate 23 and the outer shell 21. A partition plate 211 is provided on one side of the filter plate 210. The partition plate 211 is slidably disposed on the inner wall of the sealing plate 23 and the outer shell 21. A heat transfer hole 212 is provided on the inner wall of the partition plate 211. The telescopic member 213 is fixed to the partition plate 211. In the above embodiment, in the first filter assembly, filter plate 210 slides between the sealing plate 23 and the inner wall of the outer shell 21, initially filtering large particulate impurities in the gas; the partition plate 211 slides synchronously, and the heat transfer holes 212 on its inner wall control the airflow rate and velocity. The telescopic member 213 is fixed to the partition plate 211, and when the partition plate 211 is moved, the filter plate 210 can be adjusted in position synchronously to adapt to the filtration and heat transfer requirements under different working conditions.

[0021] The second filter assembly includes two slide rails 25, which are located inside the housing 21 and fixed by bolts. A filter plate 26 is slidably disposed on the inner wall of the slide rail 25, and the holes of the filter plate 26 are smaller than the holes of the filter plate 210. In the above embodiment, in the second filter assembly, the slide rail 25 is fixed inside the housing 21 by bolts, and the filter plate 26 slides inside the slide rail 25. Its aperture is smaller than that of the filter plate 210, so as to perform secondary fine filtration on the gas passing through the first filter assembly, intercept smaller particulate impurities, avoid clogging the subsequent heat transfer holes and pipelines, and improve the operational stability of the device.

[0022] The heat conduction mechanism 20 also includes an opening and closing assembly, which includes a closing cover 27. The closing cover 27 is disposed on the outside of the outer shell 21, and a plurality of closing plates 23 are provided through the closing cover 27 and the inner wall of the outer shell 21. In the above embodiment, in the opening and closing assembly, the sealing cover 27 is disposed outside the housing 21, and the sealing plate 23 passes through the sealing cover 27 and the inner wall of the housing 21. When it is necessary to replace or clean the filter plate, the sealing cover 27 can be operated to move the sealing plate 23, opening the internal channel of the housing 21, which facilitates quick maintenance of the filter assembly and reduces downtime.

[0023] The heat conduction mechanism 20 also includes two slots 28, which are opened on the inner wall of the closed cover 27. The filter plate 26 slides through the inside of the slots 28. The inner wall of the closed cover 27 has slots 29 in number equal to the number of filter plates 210. The filter plates 210 pass through the inside of the slots 29. In the above embodiment, slot 28 on the inner wall of the closed cover 27 allows filter plate 26 to slide through, and slot 29 corresponds in number to filter plate 210, allowing filter plate 210 to pass through. This structure allows filter plate 26 and filter plate 210 to be quickly pulled out or inserted along the slots, simplifying the disassembly and assembly process of the filter assembly and improving maintenance efficiency. At the same time, the limiting function of the slots ensures that the filter plates are accurately positioned after installation, ensuring filtration and heat transfer effects.

[0024] The heat conduction mechanism 20 also includes a heat inlet pipe 220, which is located outside the right heat inlet hole and is at the same horizontal level as one of the second filter components. A spare heat outlet pipe 221 is located outside the upper spare heat transfer hole. The spare heat outlet pipe 221 is located outside the outer shell 21. A main heat outlet pipe 222 is located on the side of the outer shell 21 away from the heat inlet pipe 220. The main heat outlet pipe 222 corresponds to the left heat outlet hole. In the above embodiment, the heat conduction mechanism 20 is connected to the waste heat gas through the heat inlet pipe 220. The heat inlet pipe 220 and one of the second filter components are on the same horizontal line to ensure that the gas is finely filtered before entering. Under normal operating conditions, the purified gas is output through the left heat outlet and the main heat outlet pipe 222. Under standby conditions, the gas is output through the upper standby heat transfer hole and the standby heat outlet pipe 221. The dual-pipeline design improves the reliability and redundancy of the system.

[0025] The heat transfer assembly includes a heat pipe 32, which is located at the outlet of the outer shell 21. A control valve 33 is provided outside the heat pipe 32. The standby heat outlet pipe 221 and the main heat outlet pipe 222 are fixedly connected to the heat pipe 32. In the above embodiment, in the heat transfer assembly, the heat pipe 32 is connected to the output port of the outer shell 21, and the control valve 33 is set outside the heat pipe 32 to regulate the gas flow. The standby heat pipe 221 and the main heat pipe 222 are both connected to the heat pipe 32. By switching the control valve 33, the seamless connection between the main and standby transmissions can be achieved, and a stable waste heat source can be continuously provided to the electrolysis device 31.

[0026] The platform 10 also includes two sets of casters, which are located at the bottom of the platform 10.

[0027] In the above embodiment, the two sets of omnidirectional wheels at the bottom of the vehicle platform 10 enable the entire integrated device to move flexibly. The device placement position can be quickly adjusted according to the location of the waste heat source and electrolysis requirements, improving the system's scenario adaptability and deployment efficiency, while also facilitating the overall handling and maintenance of the device.

[0028] Working principle: During operation, waste heat gas enters the right heat inlet of the outer shell 21 through the heat inlet pipe 220. The heat inlet pipe 220 is at the same horizontal level as a second filter component, and the gas is first finely filtered by it. Then, it enters the interior of the outer shell 21, where the first filter component preliminarily purifies large particulate impurities. The filter plate 210 and the partition plate 211 slide synchronously. The heat transfer hole 212 of the partition plate 211 adjusts the airflow rate. The telescopic component 213 provides power for their movement. Under normal operating conditions, the telescopic component 213 drives the insert block 216 to insert into the heat transfer hole 219 of the sealing plate 218. The heat transfer hole 24 of the sealing plate 23 is offset from the spare heat transfer hole on the outer shell 21. The purified waste heat gas enters the electrolysis transmission mechanism 30 through the left heat outlet, the main heat outlet pipe 222, and the heat conduction pipe 32. The control valve 33 adjusts the gas flow rate. When the main heat pipe 222 needs cleaning, the backup circuit is activated. The telescopic component 213 drives the insert block 216 to disengage from the heat transfer hole 219, aligning the heat transfer hole 24 with the upper backup heat transfer hole. Waste heat gas is then transported to other electrolysis units 31 via the backup heat pipe 221 and the heat conduction pipe 32, achieving maintenance without shutting down the machine. When replacing or cleaning the filter plates, the operation of the sealing cover 27 moves the sealing plate 23 to open the channel. The filter plate 26 and the filter plate 210 can be quickly installed and removed along the slots of the sealing cover 27. The casters at the bottom of the vehicle platform 10 allow the device to move flexibly to adapt to different scenario requirements.

[0029] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
