[0002] According to the patent application number "CN202021243640.2" and the invention titled "A Hydrogen Separation Device for a Hydrogen Recovery System," the specification describes a hydrogen separation device for a hydrogen recovery system, comprising a device body. The lower end of the device body has a mixed gas inlet, the end of which is connected to a filter chamber. The upper end of the filter chamber is connected to a receiving pipe. The upper end of the receiving pipe is fixedly connected to a first gas delivery pipe, the upper end of which passes through a lower sealing plate and is connected to a sleeve. A sealing plate is fixedly connected to one side of the lower sealing plate, and one side of the sealing plate is connected to the device body. This hydrogen separation device for a hydrogen recovery system has a simple structure and reasonable design. By setting up a filter chamber and filter cotton, dust particles in the mixed gas can be filtered out, improving the purity of the separated hydrogen. Furthermore, by setting up an adsorption chamber and adsorbent, harmful components in the separated mixed gas can be adsorbed, thus purifying the exhaust gas and protecting the environment. However, it still has the following drawbacks:

[0003] When separating and recovering hydrogen, only large particulate impurities and harmful gases can be adsorbed. When other gases such as oxygen and inert gases are present in the mixed gas, it is not easy to separate hydrogen from other harmless gases. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Depend on Figure 1-5 The present invention relates to a hydrogen separation and recovery device, including a base 1, and a hydrogen separation component 2 installed on the top of the base 1.

[0027] The hydrogen separation assembly 2 includes a fixed cylinder 201 fixedly installed on the top of the base 1. One end of the fixed cylinder 201 is open. A separation unit 202 is installed inside the fixed cylinder 201. A snap-fit ​​unit 203 is installed at the end of the fixed cylinder 201 near the opening. A rotating unit 204 is installed at the other end of the fixed cylinder 201. An air inlet pipe 6 is installed at the top of the fixed cylinder 201.

[0028] The separation unit 202 includes an end plate 2021 located on the side of the fixed cylinder 201 near the opening. An inner cylinder 2022 is installed on the side of the end plate 2021 near the fixed cylinder 201. The outer diameter of the inner cylinder 2022 is smaller than the inner diameter of the fixed cylinder 201. An inner cavity 2023 is formed inside the inner cylinder 2022. A separation cavity 2024 is formed inside the inner cylinder 2022. The separation cavity 2024 is located outside the inner cavity 2023 and extends to the outside of the inner cylinder 2022 away from the end plate 2021, separating... The interior of cavity 2024 is equipped with hydrogen adsorption material 2025. A connecting groove 2027 is evenly distributed on the side of separation cavity 2024 near the inner cavity 2023. Filter holes 2026 are evenly distributed on the outer side of separation cavity 2024, extending to the outer side of the inner cylinder 2022. An end tube 2028 is installed on the side of end plate 2021 away from the fixed cylinder 201, communicating with the inner cavity 2023. Fan blades 2029 are installed at equal angles on the inner wall of end tube 2028. The inner cylinder 202... A positioning rod 20212 is installed at an equal angle at the end away from the end plate 2021. An insert plate 20210 is symmetrically installed on the side of the end plate 2021 near the fixed cylinder 201. A slot 20211 is provided on the insert plate 20210. Hydrogen adsorption material 2025 is installed inside the separation chamber 2024. Filter holes 2026 are evenly distributed on the outer side of the separation chamber 2024, and connecting grooves 2027 are evenly distributed on the inner side of the separation chamber 2024. During the process of the mixed gas moving from the outer side of the inner cylinder 2022 to the inner side of the inner chamber 2023… The gas is filtered when passing through the filter hole 2026 and separated and adsorbed when passing through the hydrogen adsorption material 2025, thus facilitating use. The inner cylinder 2022 rotates under the drive of the drive gear 5, and the end tube 2028 rotates with the inner cylinder 2022, causing the fan blade 2029 to rotate and guide the airflow, facilitating hydrogen separation. At the same time, the rotation of the inner cylinder 2022 can adjust the position of the filter hole 2026, preventing the mixed gas from being filtered from the top filter hole 2026 continuously, thus avoiding filter blockage.

[0029] The snap-fit ​​unit 203 includes a protruding ring 2031 fixedly installed on the outer wall of the fixed cylinder 201 near the opening. A rotating sleeve 2032 is rotatably installed on the outer side of the protruding ring 2031. Slots 2033 are symmetrically opened on the rotating sleeve 2032. The insert plate 20210 is inserted into the interior of the slot 2033. Side cylinders 2034 are symmetrically installed on both sides of the rotating sleeve 2032. The side cylinders 2034 correspond one-to-one with the slots 2033. A snap-fit ​​rod 2035 is movably installed inside the side cylinder 2034. One end of the snap-fit ​​rod 2035 is snapped into the interior of the snap-fit ​​groove 20211. A return spring 2036 is installed at the other end of the 035, and a pull rod 2037 is installed at the other end of the locking rod 2035. The pull rod 2037 extends through to the outside of the side cylinder 2034. The locking rod 2035 engages with the locking groove 20211 to install the inner cylinder 2022. When the locking rod 2035 disengages from the locking groove 20211, the inner cylinder 2022 can be disassembled. At the same time, one end of the separation chamber 2024 extends through to the outside of the inner cylinder 2022, thereby facilitating the disassembly and assembly of the hydrogen adsorption material 2025 and facilitating the subsequent release and recovery of the adsorbed hydrogen.

[0030] The rotating unit 204 includes a limiting circular groove 2041 coaxially formed at the end of the fixed cylinder 201 away from the opening. A rotating plate 2042 is rotatably mounted inside the limiting circular groove 2041. A positioning groove 2043 is formed at equal angles on one side of the rotating plate 2042 near the inside of the fixed cylinder 201. A positioning rod 20212 is inserted into the positioning groove 2043. A driven gear 2044 is coaxially mounted on the other side of the rotating plate 2042. A driving gear 5 is meshed below the driven gear 2044. The driving gear 5 is fixedly connected to the output shaft of the drive motor 4. The drive motor 4 is fixedly mounted on the top of the mounting bracket 3. The mounting bracket 3 is fixedly mounted on the base 1.

[0031] Working principle: During operation, the inner cylinder 2022 is first inserted into the fixed cylinder 201, so that the positioning rod 20212 at the end of the inner cylinder 2022 is inserted into the positioning groove 2043 on the rotating plate 2042. The slot 20211 on the end plate 2021 is then inserted into the slot 2033 on the rotating sleeve 2032, and the locking rod 2035 is engaged in the slot 20211, thus completing the installation of the inner cylinder 2022. Subsequently, the mixed gas is introduced into the fixed cylinder 201 through the inlet pipe 6, and simultaneously the drive motor 4 is turned on, causing the drive gear 5 to rotate, thereby... Driven by the driven gear 2044, the rotating plate 2042 rotates, which in turn drives the inner cylinder 2022 to rotate. When the end pipe 2028 rotates with the inner cylinder 2022, the mixed gas is guided by the fan blade 2029. The mixed gas is filtered through the filter hole 2026 and enters the separation chamber 2024. When the mixed gas passes through the separation chamber 2024, the separation chamber 2024 adsorbs and separates the hydrogen in the mixed gas. Then the remaining mixed gas enters the inner chamber 2023 through the connecting groove 2027 and is discharged from the end pipe 2028, thus completing the separation and recovery of hydrogen.

[0032] After the hydrogen is completely separated, turn off the drive motor 4, then disengage the clamp 2035 from the clamp slot 20211, and pull the inner cylinder 2022 outward. Since the end of the separation chamber 2024 away from the end plate 2021 extends to the outside of the inner cylinder 2022, the hydrogen adsorption material 2025 used for hydrogen adsorption can be disassembled and assembled, which facilitates the separation and recovery of hydrogen.
