Description

Technical Field

[0001] This utility model relates to the field of hydrogen purification, specifically a hydrogen circulation anti-clogging purification device. Background Technology

[0002] Hydrogen (H2) is a clean and efficient energy carrier with a wide range of applications and important research value. Hydrogen purification is a key step in ensuring hydrogen quality in industry. Different application scenarios have significantly different requirements for hydrogen purity. For example, the semiconductor industry requires ultrapure hydrogen with a purity of over 99.999%, while fuel cells have strict limits on the content of impurities (such as total sulfur and formaldehyde).

[0003] The hydrogen circulation anti-clogging purification device is a device designed for the hydrogen purification needs in industrial applications. Its core is to ensure the purity of hydrogen and prevent impurities from clogging through a cyclic adsorption and regeneration process. However, most traditional hydrogen circulation anti-clogging purification devices are equipped with multiple adsorption tanks (usually 2-10) to ensure continuous purification. Each tank needs to be filled with a large amount of adsorbent (such as activated carbon or molecular sieve), resulting in a large overall size of the equipment, which is difficult to adapt to space-constrained scenarios (such as vehicle-mounted or laboratory-based). In addition, the multi-tank structure requires frequent replacement of adsorbent materials, increasing downtime and labor maintenance costs. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most traditional hydrogen circulation anti-clogging purification devices are equipped with multiple adsorption tanks to ensure continuous purification. Each tank needs to be filled with a large amount of adsorbent, resulting in a large overall size of the equipment, which is difficult to adapt to space-constrained scenarios. In addition, the multi-tank structure requires frequent replacement of adsorption materials, increasing downtime and manual maintenance costs. This utility model proposes a hydrogen circulation anti-clogging purification device.

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a hydrogen circulation anti-clogging purification device. (Refer to...) Figures 1 to 3 A hydrogen circulation anti-clogging purification device includes a waste bin 1, a cylinder 2 fixedly connected to the top of the waste bin 1, a top cover 3 snapped onto the top of the cylinder 2, an air inlet pipe 4 fixedly connected to one side of the top cover 3, and an anti-clogging mechanism 5 provided in the inner cavity of the cylinder 2.

[0025] The anti-clogging mechanism 5 includes a support frame 501, the surface of which is fixedly connected to the inner cavity of the cylinder 2. The support frame 501 is U-shaped, and bearing seats 502 are fixedly connected to both ends of the support frame 501. A rotating shaft 503 is fixedly connected to the inner wall of the inner ring of the bearing seat 502. A rotating frame 504 is fixedly connected to the surface of the rotating shaft 503, and a filter membrane 505 is fixedly connected to the inner wall of the rotating frame 504. In this hydrogen circulation anti-clogging purification device, the waste box 1 and the cylinder 2 are integrated into one unit. The air inlet pipe 4 on one side of the top cover 3 is fixedly connected to an external gas supply device. Unfiltered hydrogen is introduced into the inner cavity of the cylinder 2 through the air inlet pipe 4. The anti-clogging mechanism 5 in the inner cavity of the cylinder 2 mainly works by... A U-shaped support frame 501 is connected, and bearing seats 502 are fixedly connected to both ends of the support frame 501. A set of rotating shafts 503 is fixedly connected to each bearing seat 502. Multiple rotating frames 504 are fixedly connected to each rotating shaft 503. The rotating shafts 503 can drive the rotating frames 504 to rotate. The filter membrane 505 in the rotating frame 504 can be a hydrophobic membrane such as polytetrafluoroethylene or nylon. During the rotation of multiple rotating frames 504, solid particles and liquid water droplets in hydrogen can be effectively removed. It is often used in the coarse filtration stage. After the double layer and multiple filter membranes 505 adsorb impurities, the smoothness of subsequent hydrogen transportation is ensured, and the blockage of the pipeline by impurities during subsequent hydrogen transportation is avoided as much as possible.

[0026] Reference Figure 2 and Figure 3 A motor 6 is fixedly installed on one side of the support frame 501. The output end of the motor 6 is fixedly connected to a drive shaft 7. One end of the drive shaft 7 is rotatably connected to the inner cavity of the cylinder 2. A drive gear 8 is fixedly connected to the surface of the drive shaft 7. A driven gear 9 is fixedly connected to one end of the rotating shaft 503. The teeth of the driven gear 9 mesh with the teeth of the drive gear 8. Through the drive gear 8 and the driven gear 9, the motor 6 can drive the drive shaft 7 to rotate. During the rotation of the drive shaft 7, the drive gear 8 can be driven to rotate. One end of each rotating shaft 503 is fixedly connected to a driven gear 9. Each driven gear 9 meshes with the drive gear 8, thereby realizing the opposite rotation of the two sets of rotating shafts 503, disturbing and slowing down the flow of hydrogen in the inner cavity of the cylinder 2, improving the efficiency of the filter membrane 505 in contact with hydrogen, and further improving the efficiency of impurity removal and anti-clogging.

[0027] Reference Figure 2 and Figure 4An elastic frame 10 is slidably connected to the inner cavity of the rotating frame 504. The inner wall of the elastic frame 10 is fixedly connected to one side of the filter membrane 505. A scraper 11 is fixedly connected to one side of the elastic frame 10. One side of the scraper 11 is attached to the inner wall of the cylinder 2. A protrusion 12 is fixedly connected to the inner wall of the cylinder 2. The surface of the protrusion 12 abuts against the surface of the scraper 11. Through the elastic frame 10, the elastic frame 10 can slide along the inner cavity of the rotating frame 504. When the rotating frame 504 rotates, it drives the scraper 11 to remove the impurities attached to the inner wall of the cylinder 2. One side of the scraper 11 is obliquely set, and one end of the protrusion 12 is arc-shaped. Thus, when the scraper 11 contacts the protrusion 12, it pushes the elastic frame 10 to slide elastically along the rotating frame 504, causing the filter membrane 505 to vibrate and shake off the impurities attached to the filter membrane 505, thus ensuring the filtration efficiency of the filter membrane 505.

[0028] Reference Figure 2 The inner cavity of the waste bin 1 is fitted with a collection box 13. A sealing layer 14 is fixedly connected to the surface of the collection box 13. One side of the sealing layer 14 is attached to the inner wall of the waste bin 1. Through the collection box 13, the falling impurities can fall into the collection box 13 through the cylinder 2 for collection and centralized treatment. The sealing layer 14 can be made of rubber to seal the gap between the collection box 13 and the waste bin 1, so as to avoid hydrogen leakage as much as possible.

[0029] Reference Figure 1 and Figure 5 A first exhaust pipe 15 is fixedly connected to the surface of the cylinder 2. A gas pump 16 is fixedly connected to one end of the first exhaust pipe 15. A filter box 17 is fixedly connected to the output end of the gas pump 16. A second exhaust pipe 18 is fixedly connected to one side of the filter box 17. Through the filter box 17, the gas pump 16 can transport the hydrogen gas that has been preliminarily purified in the inner cavity of the cylinder 2 through the first exhaust pipe 15 to the filter box 17. The hydrogen gas after removing impurities can avoid clogging the port of the first exhaust pipe 15 as much as possible, ensuring flowability. The filter box 17 can be equipped with highly filterable materials such as activated carbon to further filter and purify the hydrogen gas. The second exhaust pipe 18 can be connected to external processing equipment to transport the hydrogen gas.

[0030] Working Principle: The waste bin 1 and the cylinder 2 are integrated into one unit. The air inlet pipe 4 on one side of the top cover 3 is fixedly connected to the external gas supply equipment. Unfiltered hydrogen gas is introduced into the inner cavity of the cylinder 2 through the air inlet pipe 4. The anti-clogging mechanism 5 of the inner cavity of the cylinder 2 is mainly connected by a U-shaped support frame 501. Both ends of the support frame 501 are fixedly connected to bearing seats 502. Each bearing seat 502 is fixedly connected to a set of rotating shafts 503. Multiple rotating frames 504 are fixedly connected to each rotating shaft 503. The rotating shaft 503 can drive the rotating frames 504 to rotate. The filter membrane 505 in the rotating frame 504 can be made of hydrophobic membranes such as polytetrafluoroethylene and nylon. During the rotation of multiple rotating frames 504, solid particles and liquid water droplets in the hydrogen gas can be effectively removed. This is often used in the coarse filtration stage to avoid impurities clogging the pipeline during subsequent hydrogen transportation. The motor 6 can drive the drive shaft 7 to... During the rotation of the drive shaft 7, the drive gear 8 can be driven to rotate. Each rotating shaft 503 has a driven gear 9 fixedly connected to one end. Each driven gear 9 meshes with the drive gear 8, thereby realizing the opposite rotation of the two sets of rotating shafts 503. This disturbs and slows down the flow of hydrogen in the inner cavity of the cylinder 2, improves the efficiency of the filter membrane 505 in contact with hydrogen, and further improves the impurity removal efficiency. The fallen impurities can fall into the collection box 13 through the cylinder 2 for collection and centralized treatment. The sealing layer 14 can be made of rubber to seal the gap between the collection box 13 and the waste box 1. The air pump 16 can transport the hydrogen that has been preliminarily purified in the inner cavity of the cylinder 2 to the filter box 17 through the first exhaust pipe 15. The filter box 17 can be equipped with highly filtration materials such as activated carbon to further filter and purify the hydrogen. The second exhaust pipe 18 can be connected to external processing equipment to transport hydrogen.

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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
