Description

Technical Field

[0001] This utility model relates to the field of hydrogen production technology, and more specifically, to a purification tower for hydrogen production. Background Technology

[0002] In the hydrogen production process, purification towers are mainly used to remove impurities mixed in with the hydrogen. These impurities include, but are not limited to, carbon dioxide, carbon monoxide, sulfides, water vapor, and small amounts of dust. Through purification tower treatment, the purity of the hydrogen can be improved to meet the requirements of subsequent industrial production, such as chemical synthesis and fuel cells. The working principle of a purification tower is as follows: Taking chemical absorption as an example, when the hydrogen contains acidic impurities such as carbon dioxide, an alkaline absorbent can be used in the purification tower. For example, sodium hydroxide solution can be used as the absorbent. The impure hydrogen enters from the bottom of the tower and comes into countercurrent contact with the sodium hydroxide solution sprayed from the top of the tower in the packing layer. On the surface of the packing, carbon dioxide... Carbon dioxide molecules react chemically with hydroxide ions in sodium hydroxide solution to form sodium carbonate, thereby removing carbon dioxide from hydrogen gas. Taking physical adsorption as an example, for trace impurities such as sulfides, adsorbents can be used for removal. When hydrogen gas passes through a packing layer filled with adsorbent, sulfide molecules are adsorbed onto the pore surface of the adsorbent due to intermolecular forces. The adsorbent has a huge specific surface area, and its pore structure provides a large number of adsorption sites, effectively capturing impurity molecules. When using the purification tower, users can view the internal conditions of the tower through an inspection head on the front. Since the inspection head is located on the outside of the tower, it is necessary to protect it during operation.

[0003] In related technologies, during the use of a purification tower, personnel typically use tools such as wrenches to turn the bolts connecting the inspection head, disassemble the closed cover on the front side of the inspection head, open the inspection head, and then inspect and maintain the internal condition of the tower before it can be used.

[0004] However, during the current use of purification towers, after the inspection head is disassembled and installed using bolts, the bolts are located outdoors and are affected by the external environment and dirt, which can easily lead to corrosion of the installation connection. This can result in reduced sealing of the inspection head and even leakage, affecting the stability and safety of the purification tower's inspection closure. Utility Model Content

An external connector 2 is installed at the bottom left side of the tower body 1, and an inspection head 3 is installed at the front side of the tower body 1. This provides a medium for users to inspect and cover the inspection head 3, so that users can perform protective operations on the inspection head 3 after use, avoiding the inspection head 3 from being affected by the external environment and dirt, which may cause rust, loosening, or even gas leakage inside the tower body 1. Therefore, it improves the closing stability of the inspection head 3 and the safety of the tower body 1.

[0031] Reference Figures 1-4 In a preferred embodiment, the inspection protection mechanism includes a protective cover 4, which is movably connected to the top of the inspection head 3. A protective seat 5 is fixedly connected to the rear side of the top of the inner wall of the protective cover 4. A fixing rod 6 is movably connected to the bottom inside the protective cover 4. A fixing pad 7 is fixedly connected to the top of the fixing rod 6. A fixing adjustment mechanism is fixedly connected to the top of the left side of the inner wall of the protective cover 4. The protective cover 4 is moved to the top of the inspection head 3, and the bottom of the protective seat 5 contacts the top of the inspection head 3. Then, the fixing rod 6 is moved to drive the fixing pad 7 to contact the bottom of the inspection head 3, so that the fixing rod 6 cooperates with the fixing pad 7 and the protective seat 5. The protective cover 4 can be clamped and fixed on the top of the inspection head 3 to cover and protect the inspection head 3. The fixing and adjustment mechanism includes an adjustment seat 8, an adjustment hole 9 and a stud 10. The adjustment seat 8 is fixedly connected to the top of the left side inside the protective cover 4. The adjustment hole 9 is opened on the left side of the top of the fixing rod 6 and the fixing pad 7. The stud 10 is movably connected inside the adjustment hole 9, which can provide the user with a medium to adjust the fixed height of the fixing rod 6, so that the user can change the position of the fixing rod 6 according to the actual use needs, avoiding the situation where the fixing rod 6 is difficult to adjust during use, thus improving the adaptability of the fixing rod 6.

[0032] Reference Figures 2-4In a preferred embodiment, a force-applying column 11 is movably connected inside the adjustment hole 9. A screw hole 12 is provided on the top of the force-applying column 11. The screw 10 is threadedly connected to the force-applying column 11 through the screw hole 12. This provides a medium for the screw 10 to connect with the fixed rod 6 and apply force, avoiding the situation where the screw 10 is difficult to apply lifting and adjusting force to the fixed rod 6 during use. Therefore, the connection force application effect between the screw 10 and the fixed rod 6 is improved. Connecting grooves 13 are provided on both sides of the inner wall of the adjustment hole 9. A connecting block 14 is movably connected inside the connecting groove 13. The inner side of the connecting block 14 is fixedly connected to the outer side of the force-applying column 11, which allows for rotational connection between the force-applying column 11 and the fixed rod 6. Therefore, the connection flexibility between the force-applying column 11 and the fixed rod 6 is improved.

[0033] Reference Figures 2-4 In a preferred embodiment, a rotating groove 15 is provided at the bottom of the adjusting seat 8, and a rotating seat 16 is rotatably connected inside the rotating groove 15. The bottom of the rotating seat 16 is fixedly connected to the top of the stud 10, which can provide rotational support and prevent displacement between the stud 10 and the adjusting seat 8, thus improving the connection effect between the stud 10 and the adjusting seat 8. A disk 17 is embedded and connected to the top of the inner wall of the rotating groove 15, and a magnetic chuck 18 magnetically connected to the disk 17 is embedded and connected to the top of the rotating seat 16. The rotating seat 16 can be used to magnetically position the stud 10 and the adjusting seat 8 after use, thus improving the stability of the stud 10 in use.

[0034] Reference Figure 2 In a preferred embodiment, a baffle 19 is fixedly connected to the right side of the inner wall of the protective cover 4. The front side of the baffle 19 contacts the rear side of the fixing rod 6, which can apply a blocking force to the fixing rod 6 during lifting and adjustment, thereby improving the lifting and adjustment stability of the fixing rod 6. A rubber frame 20 is fixedly connected to the rear side of the protective cover 4. The rear side of the rubber frame 20 contacts the front side of the tower body 1, which can perform contact protection between the protective cover 4 and the tower body 1, thereby improving the contact protection effect between the protective cover 4 and the tower body 1.

[0035] Specifically, the working process or working principle of this hydrogen production purification tower is as follows: During use, hold the fixed rod 6 and flip it forward, so that the fixed rod 6 drives the fixed pad 7 to be parallel to the side of the protective cover 4, preparing for the subsequent installation of the protective cover 4 on the top of the inspection head 3. At this time, the connecting block 14 rotates inside the connecting groove 13, performing a rotational connection between the force-applying column 11 and the fixed rod 6. Then, hold the protective cover 4 and move the protective seat 5 to the top of the inspection head 3, making the bottom of the protective seat 5 contact the top of the inspection head 3. At this time, the rear side of the rubber frame 20 contacts the front side of the tower body 1, performing contact protection and closure work between the protective cover 4 and the tower body 1. Then, hold the fixed rod 6 and flip it to the right, so that the rear side of the fixed rod 6 contacts the front side of the baffle 19. Since the range of motion of the connecting block 14 inside the connecting groove 13 is ninety degrees, when the rear side of the fixed strip contacts the front side of the baffle 19, it indicates that the connecting block 14 and the connecting groove... One end of the inner wall of 13 contacts the screw 10, preparing for the subsequent lifting and lowering of the fixing rod 6 by the screw 10 through the screw hole 12 and the force-applying column 11. Then, the screw 10 is rotated by hand through the screw hole 12 and the force-applying column 11 to apply a threaded lifting force to the fixing rod 6, causing the fixing rod 6 to drive the fixing pad 7 to contact and press against the bottom of the inspection head 3. This causes the fixing rod 6, together with the fixing pad 7 and the protective seat 5, to clamp and stabilize the protective cover 4 on the outside of the inspection head 3, thus covering and protecting the inspection head 3. At this time, the rotating seat 16 follows the screw 10 and rotates inside the rotating groove 15, performing a rotational connection between the screw 10 and the adjusting seat 8. Through the disk 17 and the magnetic chuck 18, the screw 10 and the adjusting seat 8 are magnetically positioned after the rotation operation, ensuring the stability of the screw 10 after the operation. This causes the fixing rod 6, together with the protective seat 5, to stably clamp and fix the protective cover 4 on the outside of the inspection head 3, thus providing stable protection for the inspection head 3.

[0036] It should be noted that the tower body 1, the external connector 2, and the inspection head 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principles are clear to those skilled in the art, so they will not be described in detail here.
