Description

Technical Field

[0001] This application relates to the field of water electrolysis for hydrogen production technology, and more specifically, to a purification module and hydrogen production and addition equipment. Background Technology

[0002] The hydrogen produced by water electrolysis contains small amounts of oxygen and water. The hydrogen entering the purifier is called the feed gas. The purpose of purification is to remove oxygen from the feed gas using a catalyst and remove water by adsorption using a desiccant. The purified hydrogen is called the product gas. The overall structure of the hydrogen purification module is quite complex. The six core functional components—deoxygenation reactor, deoxygenation cooler, deoxygenation separator, regeneration gas separator, regeneration cooler, and drying tower—along with supporting auxiliary components such as valves, pipe joints, and monitoring instruments, all need to be integrated and installed on a unified frame. In existing technologies, all core functional components are installed at the bottom of the modular frame, with auxiliary components also arranged around the core components at the bottom. This highly concentrated installation layout at the bottom of the frame leads to problems such as inconvenient installation, difficult maintenance, and complex piping connections.

[0004] The embodiments of this application are implemented as follows: In one aspect of this application, a purification module is provided, including a frame body, an upper mounting frame disposed above the frame, and a lower mounting frame disposed below the frame.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0022] Please refer to Figure 1 and Figure 2 This embodiment provides a purification module 100, including a frame body 110, an upper mounting frame 111 disposed above the frame, and a lower mounting frame 112 disposed below the frame. The upper mounting frame 111 and the lower mounting frame 112 are spaced apart along the width direction of the frame and extend along the length direction of the frame. A deoxygenation cooler 130, a deoxygenation separator 140, a regeneration gas separator 150, and a regeneration cooler 160 are installed on the upper mounting frame 111. A deoxygenation reactor 120 and a drying tower 170 are installed on the lower mounting frame 112. The deoxygenation reactor 120, the deoxygenation cooler 130, the deoxygenation separator 140, the regeneration gas separator 150, the regeneration cooler 160, and the drying tower 170 are connected in sequence by pipelines.

[0023] The main frame 110 includes several vertical bars, horizontal bars, and longitudinal bars. The vertical bars are arranged in a rectangular shape. The horizontal bars connect the tops of adjacent vertical bars and the bottoms of adjacent vertical bars. The longitudinal bars connect adjacent vertical bars distributed along the length of the frame to form a stable frame structure.

[0024] The main frame 110 serves as the supporting foundation for the module and is made of high-strength metal to ensure stable support of the weight of the upper mounting bracket 111, the lower mounting bracket 112, and various functional components. Both the upper mounting bracket 111 and the lower mounting bracket 112 are strip-shaped frame structures. The design of extending along the length of the main frame 110 allows the components to be arranged in an orderly manner along the length direction, avoiding excessive crowding in the width direction. The spacing along the width direction creates layered spaces in the vertical direction, reserving sufficient space for component installation, maintenance, and pipeline layout.

[0025] The pipeline connections of each core component follow the gas purification process logic: the raw gas first enters the deoxygenation reactor 120 of the lower mounting frame 112, and after deoxygenation by the catalyst, it is transported through pipeline to the deoxygenation cooler 130 of the upper mounting frame 111 for cooling. Then it enters the deoxygenation separator 140 to separate the condensate, and then flows into the regeneration gas separator 150 for further purification. Next, it is cooled a second time by the regeneration cooler 160, and finally it is transported through pipeline to the drying tower 170 of the lower mounting frame 112 to adsorb moisture, thus obtaining high-purity product gas.

[0026] The purification module 100 provided in this application includes a frame body 110, an upper mounting frame 111 disposed above the frame, and a lower mounting frame 112 disposed below the frame. The upper mounting frame 111 and the lower mounting frame 112 are spaced apart along the width direction of the frame and extend along the length direction of the frame. The upper mounting frame 111 is equipped with a deoxygenation cooler 130, a deoxygenation separator 140, a regeneration gas separator 150, and a regeneration cooler 160. The lower mounting frame 112 is equipped with a deoxygenation reactor 120 and a drying tower 170. The deoxygenation reactor 120, the deoxygenation cooler 130, the deoxygenation separator 140, the regeneration gas separator 150, the regeneration cooler 160, and the drying tower 170 are connected in sequence by pipelines. By employing a "layered installation" design, four core components, including the deoxygenator cooler 130 and the deoxygenator separator 140, are moved to the upper mounting frame 111, leaving only the deoxygenator reactor 120 and the drying tower 170 on the lower mounting frame 112. This breaks the spatial limitations of traditional "bottom-centralized installation." With no bottom components obstructing the upper mounting frame 111, workers can assemble components in an open space. The lower mounting frame 112 also offers significantly increased operating space due to the reduced number of components.

[0027] In one possible embodiment of this application, such as Figure 1 and Figure 2As shown, the regenerated gas separator 150, the regenerated cooler 160 and the drying tower 170 each include multiple units, and each regenerated gas separator 150 is connected to the deoxygenation separator 140 by a pipeline.

[0028] The regenerator 150, regenerator 160, and drying tower 170 are all comprised in multiple units (the specific number can be set according to the purification capacity requirements, such as 2-4 units), and the number of each component remains consistent, forming multiple parallel purification units. The inlet of each regenerator 150 is connected to the outlet of the deoxygenator 140 via an independent pipeline. The outlet of each regenerator 150 is connected to the inlet of one regenerator 160, and the outlet of each regenerator 160 is connected to the inlet of one drying tower 170. Finally, the outlets of all drying towers 170 converge to form the product gas output. Simultaneously, the pipelines of each purification unit are independently configured and equipped with independent valves, allowing for flexible start-up and shutdown of single or multiple units. The parallel arrangement of multiple sets of regenerated gas separators 150, regenerated coolers 160 and drying towers 170 can divert the raw gas to different purification units for synchronous processing, which greatly improves the overall purification capacity of the module and can adapt to the gas production needs of electrolytic water hydrogen production at different scales from low to high, avoiding the purification efficiency bottleneck caused by insufficient processing capacity of a single component.

[0029] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, a support platform 1123 is provided on one side of the lower mounting frame 112, and the deoxygenation reactor 120 is installed on the support platform 1123. The outlet of the deoxygenation reactor 120 is flush with the inlet of the deoxygenation cooler 130.

[0030] On one side of the lower mounting frame 112 along the length of the frame body 110, a support platform 1123 is welded or bolted to be perpendicular to the lower mounting frame 112. The height of the support platform 1123 is precisely set according to the installation position of the deoxygenation cooler 130. The deoxygenation reactor 120 is fixedly mounted on the support platform 1123 by bolts. After installation, it is necessary to ensure that the gas outlet at the top of the deoxygenation reactor 120 is at the same horizontal height as the gas inlet at the bottom of the deoxygenation cooler 130 on the upper mounting frame 111. The two are directly connected by a short straight pipe without significant bends. The gas outlet of the deoxygenation reactor 120 is flush with the gas inlet of the deoxygenation cooler 130, so that the pipe connecting the two can adopt a short and straight structure. This avoids the problem of longer gas flow paths and increased resistance caused by the need for bending and climbing or descending pipes in traditional high-low difference layouts, reduces pressure loss during gas transportation, and improves the overall efficiency of the purification process.

[0031] In one possible embodiment of this application, such as Figure 1 and Figure 2As shown, the lower mounting frame 112 includes a first lower crossbeam 1121 and a second lower crossbeam 1122 arranged parallel to each other below the frame body 110, and the deoxygenation reactor 120 and the drying tower 170 are arranged between the first lower crossbeam 1121 and the second lower crossbeam 1122.

[0032] The lower mounting frame 112 consists of two parallel long crossbeams, namely the first lower crossbeam 1121 and the second lower crossbeam 1122. Both crossbeams extend along the length of the frame body 110 and are fixedly connected to the vertical rods at the bottom of the frame body 110 by bolts or welding. An installation space is reserved between the two crossbeams to match the external dimensions of the deoxygenation reactor 120 and the drying tower 170. The deoxygenation reactor 120 and the drying tower 170 are distributed at intervals along the length of the frame body 110, and the bottoms of both are fixed to the first lower crossbeam 1121 and the second lower crossbeam 1122 by bolts, so that the deoxygenation reactor 120 and the drying tower 170 are stably fixed.

[0033] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the upper mounting frame 111 includes a first U-shaped beam 1111 and a second U-shaped beam 1112 arranged along the length direction on both sides of the frame body 110, a first upper crossbeam 1113 and a second upper crossbeam 1114 connecting the first U-shaped beam 1111 and the second U-shaped beam 1112, and a deoxygenation cooler 130 and a regenerated gas cooler arranged between the first upper crossbeam 1113 and the second upper crossbeam 1114.

[0034] Furthermore, the deoxygenating cooler 130 and the regenerating cooler 160 are respectively provided with a first mounting lug and a second mounting lug. The deoxygenating cooler 130 is connected to the first upper crossbeam 1113 and the second upper crossbeam 1114 through the first mounting lug, and the regenerating cooler 160 is connected to the first upper crossbeam 1113 and the second upper crossbeam 1114 through the second mounting lug.

[0035] During installation, the deoxygenating cooler 130 is aligned with the pre-set bolt holes of the first upper crossbeam 1113 and the second upper crossbeam 1114 through the bolt holes on the first mounting lug, and then fastened with bolts; the regeneration cooler 160 is connected to the first upper crossbeam 1113 and the second upper crossbeam 1114 in the same way through the second mounting lug, so that both components are rigidly fixed to the upper crossbeam through the lug.

[0036] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, multiple auxiliary connecting frames 1115 are provided on the second upper crossbeam 1114, and the regenerated gas separator 150 and the deoxygenation separator 140 are respectively installed on the auxiliary connecting frames 1115.

[0037] On the lower surface of the second upper crossbeam 1114 (the upper crossbeam arranged along the length of the frame body 110), multiple auxiliary connecting frames 1115 are welded or bolted at intervals along the length direction. The auxiliary connecting frames 1115 adopt an "L" or "U" shaped structure. The auxiliary connecting frames 1115 are provided with bolt holes that are adapted to the bottom mounting holes of the regenerated gas separator 150 and the deoxygenation separator 140. The regenerated gas separator 150 and the deoxygenation separator 140 are arranged side by side along the length direction of the second upper crossbeam 1114 and are fixed to the auxiliary connecting frames 1115 by bolts.

[0038] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the upper mounting bracket 111 is provided with multiple pipe mounting brackets 1116, through which pipes are installed.

[0039] On the first U-shaped beam 1111, the second U-shaped beam 1112, the first upper crossbeam 1113, and the second upper crossbeam 1114 of the upper mounting frame 111, multiple pipe mounting brackets 1116 are welded or bolted at intervals along the length direction. The pipe mounting brackets 1116 adopt an arc-shaped buckle or a structure with bolted pressure plates to adapt to pipes of different diameters. All pipes connecting the deoxygenator 130, deoxygenator 140, regenerator 150, and regenerator 160 on the upper mounting frame 111 are fixed by the pipe mounting brackets 1116, and rubber gaskets are installed between the pipes and the mounting brackets.

[0040] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, a hydrogen-oxygen detector 180 and an oxygen-hydrogen detector 190 are also installed on the outside of the main frame 110. The detection probe of the hydrogen-oxygen detector 180 is connected to the product gas outlet of the drying tower 170 through a sampling pipeline for real-time detection of the oxygen content in the product gas; the detection probe of the oxygen-hydrogen detector 190 is connected to the exhaust bypass (if any) or raw material gas inlet bypass of the deoxygenation reactor 120 through a sampling pipeline for real-time detection of the hydrogen content in the raw material gas or the gas discharged during the deoxygenation process; both detectors are equipped with a display screen and an alarm device, which automatically issues an audible and visual alarm when the detected value exceeds a preset threshold.

[0041] This application also discloses a hydrogen production and addition apparatus, including the purification module 100 from the foregoing embodiments.
