Description

Technical Field

[0001] This utility model specifically relates to a gas collection device for a directional flow methanol reforming hydrogen production reactor. Background Technology

[0002] Hydrogen energy, as a clean and efficient secondary energy carrier, has shown great application potential in transportation, energy storage, chemical industry and other fields. Methanol reforming hydrogen production technology has become one of the important technical routes for distributed and small-scale hydrogen supply systems due to its advantages such as wide availability of raw materials, convenient storage and transportation, and relatively mild reaction conditions.

[0003] Methanol reforming for hydrogen production typically takes place in a fixed-bed reactor equipped with a catalyst. A methanol-water vapor mixture undergoes reforming under the action of the catalyst, producing a mixed gas primarily composed of hydrogen and carbon dioxide, with trace amounts of carbon monoxide and unreacted methanol and water vapor. The high-temperature gas mixture after the reaction needs to be effectively collected and removed from the reaction zone for subsequent purification or cooling processes.

[0004] In existing methanol reforming hydrogen production reactors, the gas collection unit is a key component connecting the reaction zone and the downstream system, and its performance directly affects the efficiency and stability of the entire hydrogen production system. Existing gas collection units lack effective airflow guidance, resulting in chaotic and disordered flow of the post-reaction mixed gas upon entering the collection unit. This disordered flow exacerbates eddies and turbulence, increasing system energy consumption.

[0005] Therefore, it is necessary to invent a gas collection device for a directional flow methanol reforming hydrogen production reactor to solve the above problems. Utility Model Content

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figure 1-9 The gas collection device of the directed flow methanol reforming hydrogen production reactor shown includes a gas collection component 2 fixed on the top of the methanol reforming hydrogen production reactor 1, and the gas inlet 21 at the bottom of the gas collection component 2 is connected to the gas outlet 11 at the top of the methanol reforming hydrogen production reactor 1.

[0035] Specifically, an inlet sleeve 22 is provided at the inlet 21 to connect with the gas outlet 11, a flow guide component 3 is installed inside the inlet sleeve 22, and a support component 4 is provided between the bottom of the gas collection component 2 and the top of the methanol reforming hydrogen production reactor 1.

[0036] Specifically, the flow guiding assembly 3 includes a flow guiding shroud 31 fixed to the bottom mounting platform 23 inside the air intake sleeve 22. The outer wall of the flow guiding shroud 31 is provided with multiple flow guiding holes 32. Matching flow guiding rings 33 are installed on the outside of the multiple flow guiding holes 32. The multiple flow guiding rings 33 are evenly spaced on the outer wall of the flow guiding shroud 31, and the flow guiding rings 33 directionally adjust the flow of gas inside the flow guiding shroud 31 to the gas collecting assembly 2.

[0037] In this embodiment, the gas collection assembly 2 is connected to the top gas outlet 11 of the reactor 1 through the bottom air inlet 21. A sealing ring 25 is pressed between the mounting ring 24 of the air inlet 21 and the bottom inner side of the gas collection assembly 2 to ensure zero gas leakage.

[0038] Reference Figure 4-9 The flow guide shroud 31 is generally truncated cone in shape. The size of the multiple flow guide rings 33 gradually decreases from bottom to top. Two sets of symmetrical flow guide plates 34 are provided on the top two sides of the flow guide rings 33. The ends of the two sets of symmetrical flow guide plates 34 are provided with mounting holes 35. A rotating shaft 36 is provided in the mounting holes 35. The two ends of the rotating shaft 36 are movably fixed in the connecting seats 37. The connecting seats 37 are fixed on the top two sides of the flow guide rings 33. The outer walls of the rotating shaft 36 are provided with telescopic grooves 38. Locking components 39 matching the connecting seats 37 are provided in the telescopic grooves 38.

[0039] In this embodiment, the air guide shroud 31 is fixed on the mounting platform 23 at the bottom of the air intake sleeve 22, and is generally truncated cone-shaped. Multiple air guide rings 33 of gradually varying sizes are evenly arranged from bottom to top along the outer wall of the air guide shroud 31, and air guide plates 34 are symmetrically installed on both sides of the top of each ring.

[0040] Specifically, the outer edge of the connecting seat 37 is provided with multiple slots 371, and the locking assembly 39 includes a telescopic block 391 disposed in the telescopic groove 38. A compression spring 392 is provided between the bottom of the telescopic block 391 and the bottom of the telescopic groove 38, and the bottom of the telescopic block 391 is provided with a limiting structure that matches the telescopic groove 38. That is, the telescopic block 391 extends and retracts in the telescopic groove 38 and is locked in the slot 371. The guide plate 34 rotates synchronously with the rotating shaft 36.

[0041] Specifically, one side of the telescopic block 391 is set as an inclined surface, and the inclined surface is set on the rotating surface of the telescopic block 391, which cooperates with the slot 371 for locking.

[0042] Specifically, the guide plate 34 is disposed on the top of the guide ring 33, and the two guide plates 34 on both sides cover the top opening of the guide ring 33.

[0043] In this embodiment, when the guide plate 34 is in the unlocked state, the inclined surface of the telescopic block 391 needs to be pressed to retract it into the telescopic groove 38, compressing the spring 392 to store force. The guide plate 34 can rotate freely within the connecting seat 37 via the rotating shaft 36.

[0044] Specifically, angle locking requires rotating the guide plate 34 to the target angle to release the telescopic block 391. The spring 392 pushes the telescopic block 391 out, engaging it into the corresponding slot 371 on the outside of the connecting seat 37, thus achieving mechanical locking. The beveled design of the telescopic block 391 facilitates unidirectional engagement and prevents reverse disengagement. The guide plate 34 completely covers the top opening of the guide ring 33, forcing the gas to flow out directionally from the side guide hole 32.

[0045] Reference Figure 3 The top edge of the air intake sleeve 22 is provided with an installation ring 24 that connects to the air intake port 21. A sealing ring 25 is installed at the bottom of the installation ring 24, and the sealing ring 25 is placed between the bottom of the installation ring 24 and the bottom of the inner side of the air collection assembly 2.

[0046] In this embodiment, the mixed gas after the reforming reaction enters the inlet sleeve 22 from the reactor 1 through the gas inlet 11. After impacting the flow guide shroud 31, the gas is divided by different levels of flow guide rings 33. The lower large ring guides the large flow rate of gas, while the upper small ring finely distributes the gas. The gas is injected onto the surface of the flow guide plate 34 through the flow guide holes 32. The gas is reflected towards the center or a specific area of ​​the gas collection assembly 2 at a preset angle to avoid disordered turbulence. The directionally converged gas is transported to the downstream purification system through the connecting pipe 27.

[0047] Reference Figure 1-2 The bottom four corners of the outer wall of the gas collection component 2 are provided with positioning grooves 26. The support component 4 includes a support frame 41. The top four corners of the support frame 41 are provided with positioning angles 42 that match the positioning grooves 26. The positioning angles 42 cooperate with the positioning grooves 26 to fix the gas collection component 2 with bolts. The top of the gas collection component 2 is also provided with a connecting pipe 27 for connecting external equipment.

[0048] In this embodiment, the positioning angle 42 at the top of the support frame 41 is inserted into the positioning groove 26 at the bottom of the gas collection assembly 2 and locked with bolts to form a rigid support.

[0049] In this embodiment, the layered layout of the guide ring matches the gas velocity distribution within the reactor, ensuring uniform gas collection across the entire cross-section. The guide plate cover design forces gas to flow out from the side channels, avoiding top stagnation. The angle-adjustable guide plate can flexibly adjust the reflection angle for different operating conditions, achieving centripetal convergence of the airflow, reducing eddies, and lowering pressure loss. The spiral upward flow of the airflow can extend the gas residence time, promoting secondary reactions of heavy components. The flow-limiting effect of the guide holes 32 utilizes the fact that the aperture is much smaller than the catalyst particles, resulting in a high interception rate.

[0050] In this embodiment, the deflector plate can reduce the direct velocity of the gas and reduce the risk of particle impact and breakage. The deflector shroud 31, collar 33 and deflector plate 34 of the split structure can be made of different temperature-resistant materials.

[0051] Specifically, the clearance design between the rotating shaft 36 and the telescopic block 391 allows for thermal deformation of the component.

[0052] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
