Technical Field
[0001] This utility model relates to the field of hydrogen production reactor technology, and more specifically, to an internal flow channel structure for a hydrogen production reactor. Background Technology
[0002] With advancements in energy technology research and development, renewable energy will be more widely used in the future, and emerging power industries such as electric vehicles, hybrid vehicles, and fuel cell vehicles will play an increasingly important role. Hydrogen mainly exists on Earth in compound form and is characterized by being non-toxic, having low density, high calorific value, and clean combustion products. It is considered a promising clean energy source, and therefore, hydrogen energy has enormous potential in the field of new energy research.
[0003] Chinese patent CN202310291462.2 discloses a spiral heating tube type dimethyl ether reforming hydrogen production reactor and its application. This invention can effectively control the temperature difference inside the reactor, provide a more stable reaction environment, and effectively improve the conversion rate, hydrogen yield and thermal efficiency of dimethyl ether. However, there are still some problems. The spiral heating tube in the reactor is an integral structure, which occupies a lot of space when it is transported and moved, and is also easily obstructed during the transportation process. Therefore, we provide a flow channel structure for the internal flow channel of a hydrogen production reactor. Utility Model Content
[0004] The purpose of this invention is to provide an internal flow channel structure for a hydrogen production reactor to solve the problems mentioned in the background art.
[0005] The spiral heating tubes in some existing hydrogen production reactors are integrated structures, which occupy a large space when transporting and moving them, and are also easily obstructed during the transportation process.
[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:
[0007] An internal flow channel structure for a hydrogen production reactor includes a first bend and a second bend, which are rotatably connected. Two sets of first and second bends are provided, totaling two first bends and two second bends, connected alternately end-to-end. A first circular plate is fitted over the outside of the first bend and is fixedly connected to it. A second circular plate is fitted over the outside of the second bend and is fixedly connected to it. A groove is formed inside the first circular plate near the second circular plate, and a slider is slidably connected inside the groove. The slider is fixedly connected to the second circular plate. The groove and slider connect and limit the movement between the first and second circular plates.
[0008] Preferably, both the first and second bends are rotatably connected to a connecting pipe, which is used for the entry and exit of heat flow.
[0009] Preferably, an annular plate is fixedly connected to the outer end of the second bend near the first bend, and a groove is formed inside the first bend near the second bend. The groove cooperates with the annular plate, and the annular plate on the first bend can be inserted into the groove in the second bend to position the first bend and the second bend.
[0010] Preferably, a sealing gasket is detachably connected between the groove and the annular plate, and the sealing gasket can seal the groove and the annular plate.
[0011] Preferably, both the first and second bends are arc-shaped structures. Multiple arc-shaped first and second bends are connected end to end and can form a spiral heating tube when unfolded. The connecting tube is an L-shaped structure and is connected to the first or second bend through a first and a second circular plate.
[0012] Preferably, the cross-sections of the groove and the slider are both L-shaped, and the groove and the slider as a whole are annular structures. The slider can slide within the groove. Since the cross-sections of the groove and the slider are both L-shaped, they can limit the movement between the first circular plate and the second circular plate, so that the first circular plate and the second circular plate will not separate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] Since the first bend, the second bend, and the connecting pipe are all rotatable, the whole unit can be pressed and folded, and can be unfolded by pulling. The unfolded first bend and the second bend form a spiral heating tube. The foldable structure makes the whole unit take up less space, which is more conducive to placement and transportation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4 An internal flow channel structure for a hydrogen production reactor includes a first bend 1 and a second bend 2, which are rotatably connected. Two sets of first bends 1 and second bends 2 are provided, totaling two first bends 1 and two second bends 2, connected alternately end-to-end. A first circular plate 3 is fitted over the outside of the first bend 1 and is fixedly connected to it. A second circular plate 4 is fitted over the outside of the second bend 2 and is fixedly connected to it. A groove 5 is provided inside the first circular plate 3 near the second circular plate 4, and a slider 6 is slidably connected inside the groove 5. The slider 6 is fixedly connected to the second circular plate 4. The groove 5 and the slider 6 connect and limit the movement between the first circular plate 3 and the second circular plate 4. The first and second bends rotate more smoothly due to the action of the first circular plate 3 and the second circular plate 4.
[0022] Furthermore, both the first bend 1 and the second bend 2 are rotatably connected to a connecting pipe 7, which is used for the entry and exit of heat flow.
[0023] Furthermore, an annular plate 8 is fixedly connected to the outer end of the second bend 2 near the first bend 1, and a groove 9 is provided inside the first bend 1 near the second bend 2. The groove 9 works in conjunction with the annular plate 8, and the annular plate 8 on the first bend 1 can be inserted into the groove 9 in the second bend 2, which serves to position the first bend 1 and the second bend 2 so that the first bend 1 and the second bend 2 will not be misaligned when they rotate.
[0024] Furthermore, a sealing gasket 10 is detachably connected between the groove 9 and the annular plate 8. The sealing gasket 10 can seal the groove 9 and the annular plate 8 to ensure airtightness.
[0025] Furthermore, both the first bend 1 and the second bend 2 are arc-shaped structures. Multiple arc-shaped first bend 1 and second bend 2 are connected end to end, and can form a spiral heating tube when unfolded. The connecting tube 7 is an L-shaped structure. The connecting tube 7 is also connected to the first bend 1 or the second bend 2 through the first circular plate 3 and the second circular plate 4, and can also be rotated and unfolded or folded.
[0026] Furthermore, both the slide groove 5 and the slider 6 have L-shaped cross-sections, and both the slide groove 5 and the slider 6 are annular structures. The slider 6 can slide within the slide groove 5. Since both the slide groove 5 and the slider 6 have L-shaped cross-sections, they can limit the movement between the first circular plate 3 and the second circular plate 4, preventing the first circular plate 3 from separating from the second circular plate 4, thereby ensuring the tightness between the first bent pipe 1 and the second bent pipe 2.
[0027] The following are the steps for using this utility model: When using the internal flow channel structure of this hydrogen production reactor, the entire assembly can be placed or transported because the first bend 1, the second bend 2, and the connecting pipe 7 are all rotatable. Therefore, the entire assembly can be pressed and folded, and can be unfolded by pulling. The unfolded first bend 1 and second bend 2 form a spiral heating tube. The foldable structure makes the entire assembly occupy less space, which is more conducive to placement and transportation.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
