Description

Technical Field

[0001] This application relates to the field of water electrolysis for hydrogen production technology, and in particular to a built-in cooling gas scrubbing device. Background Technology

[0002] During the process of producing hydrogen by electrolysis of water, the hydrogen gas produced by water electrolysis will carry fine alkaline mist formed by high-temperature alkaline solution.

[0003] To remove alkaline mist from hydrogen gas, the hydrogen scrubbing unit introduces the gas into a scrubbing chamber filled with pure water. The alkaline mist dissolves upon contact with the liquid, significantly reducing the alkalinity of the gas. The scrubbed hydrogen gas is then cooled in a cooling system.

[0004] In related technologies, separate hydrogen scrubbing and cooling devices are installed. Piping is required to connect the scrubbing and cooling devices. This piping system occupies a large area, and alkaline residue can easily remain between pipes, corroding connecting components and posing a high risk of leakage. Furthermore, it is difficult to maintain. Utility Model Content

[0005] Based on this, this application provides a gas scrubbing device with a built-in cooling chamber to solve the problems of large footprint of the scrubbing device and cooling device and easy corrosion of the connecting pipes.

[0006] An internal cooling gas scrubbing device is disclosed for scrubbing and cooling gas. The device includes a first cylinder, a second cylinder, an inlet pipe, and a heat exchange pipe. The first cylinder has a first receiving cavity for containing scrubbing liquid. The second cylinder is connected to the first cylinder and has a second and a third receiving cavity, located at opposite ends of the second receiving cavity. The second receiving cavity contains coolant, and the third receiving cavity contains gas. The second and third receiving cavities are independent of each other. An inlet hole is located on the wall of the second receiving cavity near the first cylinder, and an outlet hole is located on the wall away from the first cylinder. The inlet pipe has a first end and a second end. The first end is located outside the first receiving cavity, and the second end is located inside the first receiving cavity, at least partially below the surface of the scrubbing liquid. One end of the heat exchange pipe communicates with the inlet hole, and the other end communicates with the outlet hole. The first receiving cavity is connected to the third receiving cavity via the heat exchange pipe.

[0007] In one embodiment, the built-in cooling gas scrubbing device further includes an adsorption component located within the first receiving cavity and positioned near the air inlet.

[0008] In one embodiment, the built-in cooling gas scrubbing device further includes a perforated plate located within a first receiving cavity and positioned near the end of the first cylinder facing away from the second cylinder. The perforated plate has a first through hole and a plurality of second through holes, the latter being evenly distributed around the first through hole, and the diameter of each second through hole being smaller than that of the first through hole. The second end of the air inlet pipe passes through the first through hole, and at least a portion of the second end is located on the side of the perforated plate facing away from the second cylinder.

[0009] In one embodiment, the first cylinder includes a first cylinder body and a first end cap, the first end cap being connected to one end of the first cylinder body away from the second cylinder body, and the first end cap and the first cylinder body forming a first receiving cavity.

[0010] In one embodiment, the second cylinder includes a second cylinder body, a first tube sheet flange, a second tube sheet flange, and a second end cap. One side of the first tube sheet flange is connected to one end of the second cylinder body near the first cylinder body, and the other side is connected to one end of the first cylinder body near the second cylinder body. An air inlet is provided on the first tube sheet flange. An air outlet is provided on the second tube sheet flange, the first tube sheet flange, and the second cylinder body, forming a second receiving cavity. The second end cap is located on the side of the second tube sheet flange away from the second cylinder body and is connected to the second tube sheet flange; a third receiving cavity is formed between the second end cap and the second tube sheet flange.

[0011] In one embodiment, the first cylinder further includes a first connecting flange, which is disposed between the first cylinder body and the first tube sheet flange. One side is connected to the first cylinder body, and the other side is detachably connected to the first tube sheet flange. The first tube sheet flange is detachably connected to the first cylinder body through the first connecting flange.

[0012] In one embodiment, the second cylinder further includes a second connecting flange, which is disposed between the second tube sheet flange and the second end cap. One side is detachably connected to the second tube sheet flange, and the other side is connected to the second end cap. The second end cap is detachably connected to the second tube sheet flange through the second connecting flange.

[0013] In one embodiment, the built-in cooling gas scrubbing device further includes a mounting assembly, one end of which is connected to the first cylinder, and the other end of which extends away from the first cylinder along the length of the mounting assembly.

[0014] In one embodiment, the adsorption assembly includes a support plate, a pressure plate, and a filter element. The support plate is disposed within a first receiving cavity and close to a second cylinder, and is connected to the inner wall of the first cylinder. The pressure plate is disposed within the first receiving cavity and located on the side of the support plate facing the second cylinder, and is spaced apart from the support plate. The pressure plate is connected to the inner wall of the first cylinder. The filter element is disposed between the support plate and the pressure plate.

[0015] In one embodiment, the first cylinder is provided with a washing liquid inlet and a washing liquid outlet. The washing liquid inlet is connected to the first receiving cavity, and the washing liquid outlet is connected to the first receiving cavity. Along the direction from the first cylinder to the second cylinder, the washing liquid inlet is positioned closer to the second cylinder than the washing liquid outlet.

[0016] In one embodiment, the second cylinder is provided with a coolant inlet and a coolant outlet, the coolant inlet communicating with the second receiving cavity. The coolant outlet is also communicating with the second receiving cavity, and along the direction from the first cylinder to the second cylinder, the coolant outlet is positioned closer to the first cylinder than the coolant inlet.

[0017] The aforementioned built-in cooling gas scrubbing device, by arranging the scrubbing and cooling devices vertically and directly connecting them (i.e., arranging the first and second cylinders vertically and directly connecting them), significantly reduces the floor space required and eliminates the need for connecting pipes, thus avoiding the risk of alkali solution accumulating and corroding the pipes. Furthermore, since the heat exchange tubes are also vertically oriented, even if the scrubbed hydrogen gas condenses into droplets during cooling, the droplets will fall into the first receiving cavity under gravity, rather than remaining in the heat exchange tubes. In this way, by integrating the scrubbing and cooling devices into one unit, the problem of large floor space caused by separate installations is avoided. It also prevents the problem of alkali solution accumulating in connecting pipes, which could easily corrode the pipes or connecting components. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] See Figure 1 , Figure 1 A schematic diagram of a built-in cooling gas scrubbing device 100 according to an embodiment of this application is shown. The built-in cooling scrubbing device provided by this application is used for scrubbing and cooling gases. For example, it is used to scrub and cool hydrogen produced by water electrolysis.

[0036] The built-in cooling gas scrubbing device 100 provided in this application embodiment mainly includes a first cylinder 1 and a second cylinder 2.

[0037] The first cylinder 1 is provided with a first receiving cavity 10, which is used to contain washing liquid. The washing liquid can be pure water or other solutions that can absorb alkaline mist and do not react with hydrogen.

[0038] The second cylinder 2 is connected to the first cylinder 1. The second cylinder 2 is provided with a second receiving cavity 210 and a third receiving cavity 220. The first receiving cavity 210 and the third receiving cavity 220 are respectively located at opposite ends of the second receiving cavity 210. The second receiving cavity 210 is used to contain coolant, and the third receiving cavity 220 is used to contain washed and cooled gas, such as the hydrogen gas mentioned above.

[0039] It should be noted that the second receiving cavity 210 is independent of the first receiving cavity 10, and the second receiving cavity 210 is also independent of the third receiving cavity 220. Based on this, an air inlet 211 is provided on the cavity wall of the second receiving cavity 210 near the first cylinder 1, and an air outlet 212 is provided on the cavity wall away from the first cylinder 1.

[0040] Furthermore, the built-in cooling gas scrubbing device 100 provided in this application embodiment also includes an air inlet pipe 3 and a heat exchange pipe 4. The air inlet pipe 3 has a first end 31 and a second end 32. The first end 31 is disposed outside the first receiving cavity 10, and the second end is disposed inside the first receiving cavity 10, at least partially below the surface of the scrubbing liquid. One end of the heat exchange pipe 4 is connected to the air inlet 211, and the other end is connected to the air outlet 212. The first receiving cavity 10 is connected to the third receiving cavity 220 through the heat exchange pipe 4.

[0041] The following description uses hydrogen as an example to further illustrate the built-in cooling gas scrubbing device 100 provided in this application embodiment. When using this device to scrub and cool hydrogen, hydrogen gas containing impurities can be introduced into the inlet pipe 3 from the first end 31. The gas then flows along the inlet pipe 3 and exits from the second end 32. Since the second end 32 is below the surface of the scrubbing liquid, the gas contacts the scrubbing liquid, and the impurities dissolve into the scrubbing liquid, i.e., the alkaline mist dissolves into pure water. Hydrogen, however, is insoluble in water and does not react with water, thus obtaining clean hydrogen. Further, the hydrogen flows upward along the first cylinder 1, into the inlet hole 211, and then into the heat exchange tube 4 connected to the inlet hole 211. It continues to flow upward along the heat exchange tube 4 and finally flows into the third receiving cavity 220 through the outlet hole 212. During the flow of hydrogen along the heat exchange tube 4, the heat of the hydrogen is absorbed by the coolant outside the heat exchange tube 4, thereby cooling the hydrogen.

[0042] By arranging the washing and cooling devices vertically and directly connecting them, that is, arranging the first cylinder 1 and the second cylinder 2 vertically and directly connecting them, the floor space can be greatly reduced, and the connecting pipes can be eliminated, thus avoiding the risk of alkali solution remaining in the connecting pipes and corroding them. Furthermore, since the heat exchange tube 4 is also arranged vertically, even if the washed hydrogen gas condenses into droplets during the cooling process, the droplets will fall into the first receiving cavity 10 under the influence of gravity, and will not remain in the heat exchange tube 4.

[0043] The built-in cooling gas scrubbing device 100 provided in this application integrates the scrubbing device and the cooling device into one unit, thereby avoiding the problem of large floor space caused by separate installation of the scrubbing device and the cooling device. At the same time, it also avoids the problem that alkaline solution can easily remain in the connecting pipes when the scrubbing device and the cooling device are connected, which can easily lead to corrosion of the pipes or connecting parts.

[0044] In some embodiments of this application, the second cylinder 2 is provided with an exhaust port 2200, which is disposed on the cavity wall of the second receiving cavity 210 and communicates with the third receiving cavity 220. In this way, the washed and cooled gas can be discharged from the second receiving cavity 210 for gas collection.

[0045] In some embodiments of this application, the built-in cooling gas scrubbing device 100 provided in this application further includes an adsorption component 5. The adsorption component 5 is located within the first receiving cavity 10 and is disposed near the air inlet 211.

[0046] In this way, impurities or droplets in the gas can be further removed before the gas enters the inlet 211, making the final gas purer.

[0047] The aforementioned adsorption assembly 5 mainly includes a support plate 51, a pressure plate 52, and a filter element 53. The support plate 51 is disposed within the first receiving cavity 10, close to the second cylinder 2, and is connected to the inner wall of the first cylinder 1. The pressure plate 52 is disposed within the first receiving cavity 10, located on the side of the support plate 51 facing the second cylinder 2, and is spaced apart from the support plate 51. The pressure plate 52 is also connected to the inner wall of the first cylinder 1. Based on this, the filter element 53 is disposed between the support plate 51 and the pressure plate 52. The support plate 51 supports the filter element 53, while the pressure plate 52 presses down on the filter element 53, providing a fixing function.

[0048] It should be noted that the support plate 51 and the pressure plate 52 are provided with several through holes, and the filter element 53 is also a porous structure, to ensure that the gas can flow from the first receiving cavity 10 through the adsorption component 5 and into the second receiving cavity 210.

[0049] like Figure 1 As shown, in some other embodiments of this application, the built-in cooling gas scrubbing device 100 provided in this application further includes a perforated plate 6, which is located in the first receiving cavity 10 and is disposed near the end of the first cylinder 1 that is away from the second cylinder. Figure 2As shown, the perforated plate 6 is provided with a first through hole 61 and a plurality of second through holes 62. The plurality of second through holes 62 are evenly distributed around the first through hole 61, and the diameter of the second through holes 62 is smaller than the diameter of the first through hole 61. Based on this, the second end 32 of the air intake pipe 3 passes through the first through hole 61, and at least a portion of the second end 32 is located on the side of the perforated plate 6 away from the second cylinder 2.

[0050] In this way, as the gas entering the washing chamber through the air inlet pipe 3 generates bubbles in the washing liquid, these bubbles float upwards and pass through multiple second through holes 62 provided on the perforated plate 6. This allows larger bubbles to break down into relatively smaller bubbles, enabling the alkaline mist in the gas to fully contact the washing liquid, resulting in a better washing effect. Furthermore, since the diameter of the second through holes 62 is smaller than that of the first through holes 61, this ensures that the bubbles break down into even smaller bubbles, maximizing contact with the washing liquid and improving the washing effect.

[0051] The structure of the first cylinder 1 and the second cylinder 2 will be further explained next.

[0052] In some embodiments of this application, the first cylindrical body 1 includes a first cylindrical body 11 and a first end cap 12, the first end cap 12 being connected to the end of the first cylindrical body 11 facing away from the second cylindrical body 2. The first end cap 12 and the first cylindrical body 11 enclose a first receiving cavity 10. The first cylindrical body 11 can be a cylindrical hollow cylinder, such as a cylindrical or square prism. The first end cap 12 has an opening at one end and a sealed structure at the other end. The shape of the opening of the first end cap 12 matches the shape of the first cylindrical body 11, for example, it can be a circular opening or a square opening. The first cylindrical body 11 and the first end cap 12 can be connected by welding or by a flange.

[0053] In some embodiments of this application, the second cylinder 2 includes a second cylinder body 21, a second end cap 22, a first tube sheet flange 23, and a second tube sheet flange 24.

[0054] The first tube sheet flange 23 is connected on one side to the end of the second cylinder 21 near the first cylinder 1, and on the other side to the end of the first cylinder 11 near the second cylinder 2. The first tube sheet flange 23 is provided with the aforementioned air inlet 211.

[0055] The second tube sheet flange 24 is disposed at the end of the second cylinder body 21 opposite to the first cylinder body 1 and is connected to the second cylinder body 21. The second tube sheet flange 24 is provided with the aforementioned air outlet 212. The second receiving cavity 210 is formed between the second tube sheet flange 24, the first tube sheet flange 23 and the second cylinder body 21.

[0056] The second end cap 22 is disposed on the side of the second tube sheet flange 24 opposite to the second cylinder body 21 and is connected to the second tube sheet flange 24. The second end cap 22 and the second tube sheet flange 24 form the aforementioned third receiving cavity 220. In addition, the aforementioned vent 2200 is disposed on the second end cap 22.

[0057] In this way, the first cylinder body 11 and the first end cap 12 are connected to form the first cylinder body 1, and the second cylinder body 21, the second end cap 22, the first tube sheet flange 23 and the second tube sheet flange 24 are connected to form the second cylinder body 2. Furthermore, the first cylinder body 11 is also connected to the side of the first tube sheet flange 23 away from the second end cap 22, so that the first cylinder body 1 and the second cylinder body 2 form an integrated structure, which reduces the floor space occupied.

[0058] In some embodiments of this application, the number of heat exchange tubes 4 can be multiple, and there is a gap between adjacent heat exchange tubes 4. Based on this, as Figure 3 As shown, there are multiple air inlets 211, and one air inlet 211 corresponds to one heat exchange tube 4. Furthermore, the number of air outlets 212 also corresponds to the number of heat exchange tubes 4.

[0059] In some embodiments of this application, the first cylindrical body 1 further includes a first connecting flange 111. The first connecting flange 111 is disposed between the first cylindrical body 11 and the first tube sheet flange 23. One side of the first connecting flange 111 is connected to the first cylindrical body 11, and the other side is detachably connected to the first tube sheet flange 23. That is, the first tube sheet flange 23 is detachably connected to the first cylindrical body 11 via the first connecting flange 111. It is understood that the first connecting flange 111 has an annular structure and will not block the opening of the first receiving cavity 10 towards the second cylindrical body 2.

[0060] In this way, the detachable connection between the first connecting flange 111 and the first tube sheet flange 23 facilitates later inspection and maintenance. For example, when it is necessary to replace the filter element 53 in the adsorption assembly 5 located in the first receiving cavity 10, the connection between the first connecting flange 111 and the first tube sheet flange 23 can be disconnected to open the first receiving cavity 10.

[0061] In other embodiments of this application, the second cylinder 2 further includes a second connecting flange 222, which is disposed between the second tube sheet flange 24 and the second end cap 22. One side of the second connecting flange 222 is detachably connected to the second tube sheet flange 24, and the other side is connected to the second end cap 22. The second end cap 22 is detachably connected to the second tube sheet flange 24 via the second connecting flange 222.

[0062] In summary, it can be understood that the second receiving cavity 210, i.e., the cooling device, is detachably connected between the first receiving cavity 10 and the third receiving cavity 220. When maintenance of the cooling device is required, for example, when the heat exchange tube 4 needs to be replaced, the first tube sheet flange 23 can be released from the first connecting flange 111, and the second tube sheet flange 24 can be released from the second connecting flange 222, thereby removing the second cylinder 21 for maintenance of the heat exchange tube 4 located therein. Simultaneously, the components constituting the first receiving cavity 10, the second receiving cavity 210, and the third receiving cavity 220 can be assembled and connected separately before being fixed into a whole, which reduces the installation difficulty of the built-in cooling gas scrubbing device 100 provided in this application.

[0063] In some embodiments of this application, the built-in cooling gas scrubbing device 100 further includes a mounting assembly 7. One end of the mounting assembly 7 is connected to the first cylinder 1, and the other end extends away from the first cylinder 1 along the length of the mounting assembly 7.

[0064] In this way, the portion of the mounting component 7 extending away from the first cylinder 1 along its length can provide an installation and fixing position for the built-in cooling gas scrubbing device 100 provided in this application. For example, the extended portion of the mounting component 7 can be attached to the support frame, or mounting holes can be provided on the extended portion of the mounting component 7 so that the built-in cooling gas scrubbing device 100 can be installed and fixed using connectors.

[0065] The number of the aforementioned mounting components 7 can be multiple, with multiple mounting components 7 spaced apart along the outer periphery of the first cylinder 1. In addition, the mounting components 7 can also be connected to the outer wall of the second cylinder 2, or simultaneously connected to the outer walls of the first cylinder 1 and the second cylinder 2.

[0066] In some embodiments of this application, a washing liquid inlet 81 is provided on the first cylinder 1, and the washing liquid inlet 81 communicates with the first receiving cavity 10. A washing liquid outlet 82 is also provided on the first cylinder 1, and the washing liquid outlet 82 communicates with the first receiving cavity 10. Based on this, along the direction from the first cylinder 1 to the second cylinder 2, the washing liquid inlet 81 is positioned closer to the second cylinder 2 than the washing liquid outlet 82.

[0067] In this way, washing liquid can be added to the first receiving cavity 10 through the washing liquid inlet 81, and waste liquid can be discharged from the first receiving cavity 10 through the washing liquid outlet 82. And since the washing liquid outlet 82 is set lower than the washing liquid inlet 81, the waste liquid can automatically flow out of the first receiving cavity 10 under the action of gravity.

[0068] In some other embodiments of this application, the second cylinder 2 is provided with a coolant inlet 91 and a coolant outlet 92. The coolant inlet 91 communicates with the second receiving cavity 210, and the coolant outlet 92 communicates with the second receiving cavity 210. Along the direction from the first cylinder 1 to the second cylinder 2, the coolant outlet 92 is located closer to the first cylinder 1 than the coolant inlet 91, that is, the location of the coolant outlet 92 is relatively low.

[0069] In this way, the coolant in the second receiving cavity 210 can be circulated through the coolant inlet 91 and the coolant outlet 92 to ensure that the coolant can effectively cool the gas in the heat exchange tube 4.

[0070] In some embodiments of this application, the first cylinder 1 is further provided with an overflow port 83, which is located below one end 31 of the air inlet pipe 3. In this way, when there is too much washing liquid in the first receiving cavity 10, it can overflow from the first receiving cavity 10 through the overflow port 83 to ensure the pressure balance in the first receiving cavity 10, and to ensure that the washing liquid will not invade the heat exchange tube 4 due to excessive washing liquid, thereby avoiding corrosion of the heat exchange tube by the alkaline washing liquid.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
