[0049] This description may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," each of which may refer to one or more of the same or different embodiments according to the present disclosure.
[0050] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0051] like Figure 1 、 Figure 2 、 Figure 3 As shown, an embodiment of the present invention provides an integrated hydrogen production reactor, comprising:
[0052] The thermal system includes a stacked and correspondingly connected heat exchange module 2, combustion module 3, and flue gas settling module 4, wherein a first gap 10 is provided between the heat exchange module 2, combustion module 3, and settling module;
[0053] The hydrogen system 5 includes at least a stacked and correspondingly connected catalytic module 6, a feed module 7, and a hydrogen-rich settling module 8, wherein the hydrogen-rich settling module has a hydrogen-rich outlet 9, and a second gap 11 is formed between the catalytic module 6, the feed module 7, and the hydrogen-rich settling module 8;
[0054] The thermal system and the hydrogen system 5 are arranged in a corresponding manner based on the first interval 10 and the second interval 11, so that the feeding module 7 and the heat exchange module 2 can exchange heat, and the combustion module 3 and the flue gas deposition module 4 can provide the catalytic module 6 with the heat energy required for the reaction.
[0055] The thermal system in this embodiment can be regarded as an integral part, and the hydrogen system 5 can be regarded as an integral part. The thermal system is mainly used for combustion and heat generation to provide heat for the hydrogen production reaction of the hydrogen system 5. The thermal system includes a heat exchange module 2, a combustion module 3, and a flue gas deposition module 4. The three modules are independent modules and are stacked. The specific arrangement position of the three modules is not fixed. For example, it can be but not limited to the following: Figure 1 、 Figure 2 The directions shown are from bottom to top the heat exchange module 2, the combustion module 3, and the flue gas deposition module 4. The heat exchange module 2 and the flue gas deposition module 4 may also be swapped in position. The three modules are connected in sequence through a connecting structure. The connecting structure may be an independently arranged structure or may be formed by extending the structure of the module itself. The heat exchange module 2, the combustion module 3, and the flue gas deposition module 4 are spaced apart from each other, and the specific spacing size is not fixed, that is, the first spacing 10 between two adjacent modules may be the same or different. The hydrogen system 5 is mainly used to receive liquid fuel and prepare hydrogen-rich gas. The hydrogen system 5 includes at least a heat exchange module 2, a combustion module 3, and a flue gas deposition module 4. The three modules are also independent modules. The three modules are stacked and the specific arrangement position is still not fixed. For example, it can be but is not limited to: Figure 1、 Figure 2 The directions shown are, from bottom to top, the feed module 7, the catalytic module 6, and the hydrogen-rich sedimentation module 8, respectively. The catalytic module 6 and the hydrogen-rich sedimentation module 8 may also be swapped in position, etc. The three modules are connected in sequence through a connecting structure, and the connecting structure may be an independently arranged structure or may be formed by extending the structure of the module itself. The catalytic module 6, the feed module 7, and the hydrogen-rich sedimentation module 8 have the same or different second intervals 11. The specific size of the first interval 10 and the second interval 11 mainly depends on the size of the module to be inserted. When connecting the thermal system and the hydrogen system 5, the two systems are plugged together based on their respective first intervals 10 and second intervals 11, so that the different modules of the thermal system and the hydrogen system 5 are abutted against each other and stacked to form a whole, thereby realizing an integrated hydrogen production reactor. Since the arrangement order between the modules in each system is different, the order between the modules in the formed integrated hydrogen production reactor is also uncertain and can be adjusted according to actual needs.
[0056] In actual application, an outer shell can be provided to encapsulate the modules after being interlaced and connected, and corresponding holes can be opened at the inlets and outlets where raw materials need to be connected, hydrogen or other gases need to be exported, so as to achieve communication between the inlets and outlets and the outside.
[0057] Based on the above embodiments, it can be seen that the overall structure of the reactor is simple and compact, supports a small volume design, can be carried out, is easy to disassemble, and is easy to maintain. In addition, the hydrogen production efficiency is high and the operation is convenient. Only liquid fuel needs to be fed into the reactor, and the reactor can undergo heat exchange, evaporation, reaction to produce hydrogen, and dust removal inside, and then output rich hydrogen gas to the outside. In addition, during the hydrogen production reaction, there is no need to add an additional heat source. The lean hydrogen gas and air received by the integrated reactor are directly used to mix to form a combustible gas. The heat generated by the combustion module 3 can provide sufficient heat source for the evaporation and hydrogen production reaction process, while achieving the treatment of the hydrogen-poor waste gas. Moreover, the integrated hydrogen production reactor in this embodiment actually adopts a layered structure design, that is, each module is "stacked layer by layer", and all conveying structures can be integrated within or between the layer structures. There can be no external structural parts around the reactor, thereby reducing the cumbersome transmission pipeline design, greatly simplifying the process, and reducing the preparation cost and subsequent maintenance cost of the reactor.
[0058] Furthermore, the hydrogen-rich gas outlet 9 in this embodiment is connected to an external purifier for purifying hydrogen and hydrogen-depleted gas. As shown in the figure, in one embodiment, the hydrogen-rich gas outlet 9 can be, but is not limited to, located at the top of the reactor, for example, by arranging the hydrogen-rich settling module 8 at the top layer. Of course, the hydrogen-rich gas outlet 9 can also be located around the circumference of the reactor, and the specific arrangement is not exclusive.
[0059] The combustion module 3 has an air inlet end and a lean hydrogen inlet end 12 connected to the purifier. The combustion module 3 burns the lean hydrogen and air to generate flue gas. The flue gas flows into the flue gas settling module 4 for settling, and then flows into the heat exchange module 2 to provide heat medium for the heat exchange module 2.
[0060] Continue to combine Figure 1 、 Figure 2 and Figure 3 As shown, the heat exchange module 2 includes a plurality of stacked and spaced heat exchange layers 13, each of which is interconnected. For example, the first, second, and third heat exchange layers 13 are interconnected via interconnecting pipes, or the first, second, and third heat exchange layers 13 are integrally formed, with the layers interconnected by extensions of the structure. The number of heat exchange layers 13 is not fixed and can be one, two, three, or even more layers, without limitation. The feed module 7 includes a plurality of stacked and spaced feed layers 14, each of which is interconnected, with the multiple heat exchange layers 13 interspersed with the feed layers 14. The number of feed layers 14 can be the same as or less than the number of heat exchange layers 13, depending on the interspersing method. The feed layers 14 can also be interconnected via interconnecting pipes, or can be integrally formed, with the layers interconnected by extensions of their own structures. There are various implementation methods. Since the feed layer 14 is used to introduce the raw material liquid, its temperature is lower than the reaction requirements and it cannot participate in the hydrogen production reaction. Therefore, it needs to be heated. The flue gas generated by the reactor is high and cannot be directly discharged. Therefore, the flue gas is used to exchange heat with the raw material liquid. This can not only heat the raw material to form a gas-liquid mixture, but also cool the flue gas so that it can be discharged smoothly without causing safety hazards.
[0061] like Figure 2 、 Figure 3 As shown, in one embodiment, the heat exchange layer 13 is formed by a first pipe, and the first pipe is bent in a first direction to form a plurality of first protrusions 15, so that the first pipe is circuitous. That is, the first protrusions 15 of each heat exchange layer 13 are all formed by protruding and arching in the first direction. For each heat exchange layer 13, its first direction is not fixed. The first direction mainly refers to that all the first protrusions in the heat exchange layer 13 are oriented in the same direction, and the first direction is the direction. The first protrusion 15 can be arched or bent to form a rectangular open frame. The specific structure can be referred to in the attached figure. Figure 2 and Figure 3 The structural shape of the first protrusion 15 is not limited to the above-mentioned form, and can also be other shapes.
[0062] To achieve interpenetration, the spacing between two adjacent first protrusions 15 in this embodiment is greater than the spacing between the two first pipe sections forming the first protrusions 15. A first recess 16 is formed between the two adjacent first protrusions 15. That is, the two pipe sections forming the first protrusions 15 are in contact with each other, and the two adjacent first protrusions 15 are spaced apart from each other, so that the two first protrusions 15 cooperate to form a slot, and each first protrusion 15 forms an insert. The heat exchange layer 13 has multiple slots and inserts.
[0063] The feed layer 14 is formed by a second pipe, and the second pipe is bent in a second direction (which has the same meaning as the first direction) to form a plurality of second protrusions 17, so that the second pipe is in a circuitous shape. The second protrusions 17 of the feed layer 14 have the same structure as the first protrusions mentioned above, and the sizes can be the same or different. The second protrusions 17 are also used to form an insert. The distance between two adjacent second protrusions 17 is greater than the distance between the two sections of the second pipe used to form the second protrusions 17, so that a second recess 18 is formed between two adjacent second protrusions 17, that is, a slot is formed. The feed layer 14 has multiple slots and inserts in the second direction. The first direction and the second direction of the heat exchange layer 13 and the feed layer 14 corresponding to each other are opposite to each other, and the setting positions of the first protrusion and the second protrusion are staggered, and the setting positions of the first recess 16 and the second recess 18 are staggered. When assembling the thermal system and hydrogen system 5, in this embodiment, the corresponding heat exchange layers 13 and feed layers 14 are interlaced with each other. Specifically, the first protrusions 15 of the two layers are correspondingly inserted into the second recesses 18, and the second protrusions 17 are correspondingly inserted into the first recesses 16. In actual application of this embodiment, the number of heat exchange layers 13 and feed layers 14 can be the same, or the number of heat exchange layers 13 can be greater than the number of feed layers 14 to achieve efficient heating of the low-temperature raw materials in the raw material layer.
[0064] In another embodiment, if Figure 4 and Figure 5 As shown, the heat exchange layer 13 is formed by a circuitous third pipe, and the feed layer 14 is formed by a circuitous fourth pipe. When multiple heat exchange layers 13 and feed layers 14 are interlaced, the heat exchange layers 13 and feed layers 14 are staggered in the stacking direction. For example, the third pipe is bent and folded like a dense wave to form the heat exchange layer 13, and the fourth pipe is also bent and folded like a dense wave to form the feed layer 14. The bent third and fourth pipes each form a plate-like layer. When the heat exchange layers 13 and feed layers 14 are interlaced, the heat exchange layers 13 and feed layers 14 are stacked in an interlaced manner, so that a feed layer 14 is sandwiched between two heat exchange layers 13.
[0065] In yet another embodiment, Figure 6 and Figure 7 As shown, the heat exchange layer 13 is formed by a circuitous fifth pipe, and the feed layer 14 is formed by a circuitous sixth pipe. When multiple heat exchange layers 13 and feed layers 14 are interlaced, the fifth pipe is inserted into the corresponding sixth pipe. That is, the sixth pipe is formed by a thicker pipe, and the fifth pipe is formed by a thinner pipe. The fifth and sixth pipes bend and curve in the same direction, so that the fifth pipe can be inserted into the sixth pipe, achieving an interlaced arrangement. Alternatively, the sixth pipe is formed by a combination of multiple thin pipes, which are radially connected to each other with a certain spacing, or multiple thin pipes are closely abutted and connected to form a hollow sixth pipe, and the fifth pipe is inserted into the sixth pipe. As the length of the pipes increases, they can extend in the stacking direction, thereby forming multiple layers of heat exchange layers 13 and feed layers 14.
[0066] In practical applications, thermal system 1 and hydrogen system 5 can each be provided with an independent outer shell to encapsulate the modules within the system, which can then be interlaced and connected to form a whole. When encapsulating the system within, the shell can include multiple sections, each used to encapsulate a different module. For example, each module can be encapsulated independently, or two adjacent modules can be encapsulated together, or only some modules can be encapsulated. For example, all modules in the thermal system except heat exchange module 2 can be encapsulated together, while heat exchange module 2 is not encapsulated. This configuration can make the system more independent, facilitating independent maintenance and portability.
[0067] The combustion module 3 is in a plate-like shape, and can also be formed by bending a tube body, or have a flow channel inside to allow the raw gas or gas-liquid mixture to stay in the combustion module 3 for a longer time, achieve sufficient combustion, and generate a mixture containing hydrogen-rich gas.
[0068] For designs with low hydrogen production requirements and fewer layers within heat exchange module 2, closer to combustion module 3, evaporation module 19 can be omitted and still achieve feedstock vaporization. However, for designs with higher hydrogen production requirements and more layers within heat exchange module 2, evaporation module 19 is required to assist in fully vaporizing the feedstock gas-liquid mixture and ensure sufficient combustion upon subsequent entry into the fuel module.
[0069] For example, Figure 1 and Figure 3 As shown, the hydrogen system 5 also includes an evaporation module 19 formed by a circuitous seventh pipe. The evaporation module 19 is inserted between the heat exchange module 2 and the combustion module 3, and is connected to the feed module 7. It is used to receive the gas-liquid mixture after heat exchange transmitted by the feed module 7, and evaporate the gas-liquid mixture into fuel gas by absorbing the heat energy generated by the combustion module 3.
[0070] Furthermore, the catalytic module 6 is formed by a circuitous eighth conduit filled with catalyst, which is also bent and curved to form a lamellar structure, and the interior of the conduit is filled with catalyst. The inlet end of the catalytic module 6 is connected to the evaporation module 19 or the feed module 7. For example, a reactor with an evaporation module 19 is connected to the evaporation module 19, while a reactor without an evaporation module 19 is connected to the feed module 7. The outlet end of the catalytic module 6 is connected to the hydrogen-rich settling module 8. Both the inlet and outlet ends of the catalytic module 6 are equipped with a blocking structure 20 for limiting the flow of fuel gas and preventing catalyst overflow.
[0071] Specifically, the blocking structure 20 in this embodiment is formed by a tube array, i.e., a plurality of small tubes arranged in rows and columns. This not only allows gas to pass through, but also prevents catalyst from escaping. Alternatively, the blocking structure 20 may be configured as a multi-layer filter screen, filter membrane, or the like. The specific structure is not limited to the above embodiment.
[0072] Continue to combine Figure 1 As shown, the hydrogen-rich settling module 8 is formed by a circuitous ninth conduit, the flue gas settling module 4 is formed by a circuitous tenth conduit, and the catalytic module 6 is interspersed between the flue gas settling module 4 and the combustion module 3. The specific bends, curvatures, and degree of curvature of the ninth and tenth conduits are variable and can be determined based on the required length of the conduits, the required cross-sectional area of the reactor, and other factors. The configuration of the conduits in the other modules also meets the above requirements. The hydrogen-rich settling module 8 and the flue gas settling module 4 are similarly similar to plate-layer structures, with the planes of the plate-layer structures / layered structures corresponding to all modules parallel and perpendicular to the stacking direction.
[0073] In order to standardize the overall structure of the reactor, all modules in this embodiment, including the heat exchange module 2, the combustion module 3, the flue gas sedimentation module 4, the catalytic module 6, the feed module 7, and the hydrogen-rich sedimentation module 8, have a uniform overall shape, such as a cubic structure with a rectangular, circular, etc. cross-section, and the cross-sectional dimensions of each module are the same, but the height (thickness) may be different.
[0074] Specifically, in one embodiment, Figure 1 、 Figure 2 and Figure 3As shown, the top layer of the hydrogen-rich sedimentation module 8 reactor is provided with a flue gas sedimentation module 4 below it, a catalytic module 6 below the flue gas sedimentation module 4, a combustion module 3 below the catalytic module 6, an evaporation module 19 below the combustion module 3, and a heat exchange module 2 and a feed module 7 below the evaporation module 19. The connecting structures between the modules are arranged along the stacking direction and are all located within the module or between the modules. Each module can be provided with a corresponding avoidance structure, such as a recess, a through hole, etc., which is not limited to the specific structure. In this way, the reactor can be planar all around, reducing space occupation and being easy to store and carry. Among them, the hydrogen-rich outlet port 9 is located on the hydrogen-rich sedimentation layer, which is provided with a hydrogen-rich filter 21. The hydrogen-poor inlet port 12 also extends to the hydrogen-rich sedimentation module 8, that is, extends to the top of the reactor. The hydrogen-poor inlet port 12 is provided with a hydrogen-poor filter 22 and a throttle 23.
[0075] In this embodiment, Figure 1 As shown, the throttle 23 is tubular and arranged along the stacking direction. The middle part of the throttle 23 is radially inwardly contracted to form a bottleneck shape, as shown in the reference figure. The throttle 23 passes through the adjacent module and is connected to the combustion module 3, or is adjacent to the combustion module 3 and directly connected to the combustion module 3. For example, continuing with the above embodiment, the hydrogen-rich sedimentation layer in this embodiment can be provided with a hole or a gap to provide space for the connection between the throttle 23 and the combustion module 3, so that the throttle 23 can be directly connected to the combustion module 3 in the stacking direction. Alternatively, the hydrogen-rich sedimentation module 8 can maintain its original structural state, and the throttle 23 can be in the shape of a curved tube as a whole, so that it can bypass the hydrogen-rich sedimentation module 8 and be connected to one side of the combustion module 3. The specific method is not unique.
