Description

Technical Field

[0001] This utility model relates to the field of hydrogen recovery technology, and more specifically, to a hydrogen recovery and separation device. Background Technology

[0002] In hydrogen recovery systems, purification towers can serve as pretreatment equipment. When the mixed gas contains a large number of impurities, such as sulfides, carbon dioxide, and dust, the purification tower can perform preliminary separation of these impurities. For example, in the process of producing hydrogen from coal, the crude hydrogen produced may contain impurities such as hydrogen sulfide. The purification tower can use a suitable absorbent, such as an amine absorbent, to absorb the hydrogen sulfide, reducing the processing burden on subsequent hydrogen separation equipment and protecting the downstream equipment. The purification tower mainly utilizes the contact between gas and liquid to separate and remove impurities. When the gas containing impurities enters the purification tower, the liquid, usually an absorbent or detergent, is sprayed into a mist through the spray device inside the tower, allowing the gas and liquid to come into full contact. The impurity components in the gas will undergo physical absorption, such as dissolution, and chemical reactions, such as acid-base neutralization, with the liquid, thereby being absorbed or transformed by the liquid, achieving the purpose of purifying the gas and separating the impurities from the gas. Since the gas rises directly when entering the tower for separation and purification, it is necessary to perform separation operations on the incoming gas.

[0003] In related technologies, during the use of purification towers, external gas pipes are generally connected to the tower body through connectors, allowing the gas to enter the tower body through the connectors for separation and purification before use.

[0004] However, in the current use of purification towers, due to the large number of impurities in the hydrogen source gas and the fact that the hydrogen source gas directly enters the tower body, it can only perform spray separation of impurities in the hydrogen source gas. Moreover, during spray separation, the hydrogen source gas carries impurities upward and comes into contact with the filter media inside the tower body, which easily causes adhesion and blockage of the filter media, resulting in reduced filter flow and affecting the smoothness of hydrogen recovery and separation and the effect of impurity separation and removal.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a hydrogen recovery and separation device, including a tower body 1 and a gas separation mechanism. A conduit 2 is installed on the top of the tower body 1, and an air inlet 3 is installed at the bottom left side of the tower body 1. The device can separate the hydrogen source gas after it enters the tower body 1 into the liquid inside the tower body 1, and perform preliminary separation of impurities inside the hydrogen source gas. This avoids the situation where the hydrogen source gas directly carries impurities upward and blocks the filter material inside the tower body 1, thus improving the smoothness of hydrogen recovery and the impurity removal effect of the tower body 1.

[0031] Reference Figures 1-4 In a preferred embodiment, the gas separation mechanism includes a separation cylinder 4, which is movably connected to the bottom left side of the tower body 1. An inlet cylinder 5 located inside an inlet head 3 is fixedly connected to the left side of the separation cylinder 4. A separation head 6 is fixedly connected to the bottom of the separation cylinder 4, and a separation pipe 7 is movably connected to the bottom of the separation head 6. A separation hole 8 is provided at the bottom of the surface of the separation pipe 7. Separation connection mechanisms are provided on both sides of the top of the separation pipe 7. The separation cylinder 4 collects the hydrogen source gas entering the tower body 1 through the inlet head 3 and guides the hydrogen source gas into the separation pipe 7 through the separation head 6. Since the separation hole 8 on the surface of the separation pipe 7 is located in the liquid at the bottom of the tower body 1, when the hydrogen source gas enters the separation pipe 7, the separation pipe 7 cooperates with the separation hole 8 to separate the hydrogen source gas. The gas source gas is separated into the liquid, forming several bubbles which then burst, allowing the liquid inside the tower body 1 to perform a preliminary adsorption and separation of impurities in the hydrogen source gas. The separation connection mechanism includes a connection port 9, a connection groove 10, and a connection block 11. The connection port 9 is located on both sides of the top of the separation tube 7, and the connection groove 10 is located at the bottom of the inner wall of the connection port 9. The connection block 11 is movably connected inside the connection groove 10, and the inner side of the connection block 11 is fixedly connected to the surface of the separation head 6. This allows for stable separation and connection between the separation tube 7 and the separation head 6, facilitating the user's installation and connection operations between the separation tube 7 and the separation head 6. This avoids situations where the separation tube 7 is difficult to connect and install with the separation head 6, thus improving the ease of connection and installation between the separation tube 7 and the separation head 6.

[0032] Reference Figures 2-3In a preferred embodiment, a fixing ring 12 located at the bottom of the connecting groove 10 is fixedly connected to the top of the inner wall of the separation tube 7, and a sealing ring 13 is fixedly connected to the top of the fixing ring 12. This can seal the connection between the separation head 6 and the separation tube 7, avoiding the situation where it is difficult to seal the connection between the separation head 6 and the separation tube 7. Therefore, the sealing effect of the connection between the separation tube 7 and the separation head 6 is improved. A gas plate 14 located inside the separation hole 8 is fixedly connected to the bottom of the inner wall of the separation tube 7. The top of the gas plate 14 has a gas hole 15, which can disperse the hydrogen source gas entering the separation tube 7, so that the separation tube 7 can better separate the hydrogen source gas in the liquid.

[0033] Reference Figures 2-4 In a preferred embodiment, a screw 16 is movably connected to the right side of the separating cylinder 4, and a screw cylinder 17 is threadedly connected to the right side of the surface of the screw 16. This allows a supporting and stabilizing force to be applied between the separating cylinder 4 and the tower body 1, so that the user can stabilize the separating cylinder 4 inside the tower body 1. A connecting seat 18 is fixedly connected to the right side of the separating cylinder 4, and a connecting head 19 is movably connected inside the connecting seat 18. The right side of the connecting head 19 is fixedly connected to the left side of the screw 16, which allows for assembly and connection between the screw 16 and the separating cylinder 4, thus improving the connection effect between the screw 16 and the separating cylinder 4.

[0034] Reference Figures 2-4 In a preferred embodiment, a positioning post 20 is movably connected to the top of the connecting seat 18, and a positioning groove 21 is provided on the top of the connector 19. The bottom of the positioning post 20 is located inside the positioning groove 21. The connector 19 can be used to perform insertion and positioning work between the screw 16 and the connecting seat 18, thus improving the connection and positioning effect of the connector 19 on the screw 16. A magnetic ring 22 located outside the positioning post 20 is embedded in the top of the inside of the connecting seat 18, and a magnetic suction ring 23 magnetically connected to the magnetic ring 22 is embedded in the surface of the positioning post 20. The positioning post 20 and the connecting seat 18 can be magnetically positioned, thus improving the positioning stability of the positioning post 20.

[0035] Specifically, the working process or principle of this hydrogen recovery and separation device is as follows: During use, after the tower body 1 is connected to the external hydrogen source gas delivery pipe through the inlet head 3, the external hydrogen source gas enters the tower body 1 through the inlet head 3. Then, the hydrogen source gas enters the separation cylinder 4 through the inlet cylinder 5. At this time, the separation cylinder 4 concentrates the hydrogen source gas entering the tower body 1. Simultaneously, the separation head 6 guides the hydrogen source gas inside the separation cylinder 4 to the separation pipe 7. Since the separation holes 8 on the surface of the separation pipe 7 are located in the liquid at the bottom of the tower body 1, when the hydrogen source gas enters the separation pipe 7, the separation pipe 7, in conjunction with the separation holes 8, separates the hydrogen source gas into the liquid at the bottom of the tower body 1. At this time, the gas plate 14, in conjunction with the gas holes 15, assists the separation pipe 7 in separating the hydrogen source gas more evenly into the liquid. Simultaneously, the connecting block 11, in conjunction with the connecting groove 10, ensures a stable connection between the separation pipe 7 and the separation head 6. The connection between the separation head 6 and the separation tube 7 is sealed by the fixing ring 12 and the sealing ring 13, causing the hydrogen source gas to form several bubbles in the liquid at the bottom of the tower body 1 and burst. This causes the liquid at the bottom of the tower body 1 to perform preliminary adsorption and separation of impurities in the hydrogen source gas entering the tower body 1. During this process, the screw 16 and the screw cylinder 17 apply a clamping and supporting stabilizing force between the separation cylinder 4 and the tower body 1 through the connector 19 and the connecting seat 18, stabilizing the separation cylinder 4 inside the tower body 1. At the same time, the magnetic ring 22 and the magnetic suction ring 23 connect and position the connector 19, the screw 16 and the separation cylinder 4 through the positioning column 20 and the positioning groove 21, ensuring the supporting effect of the screw 16 on the separation cylinder 4, and stabilizing the separation cylinder 4 and the separation tube 7 at the bottom of the tower body 1, thus separating the hydrogen source gas that enters the tower body 1 through the gas inlet 3.

[0036] It should be noted that the tower body 1, the duct 2 and the air inlet 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 principle are clear to those skilled in the art, so they will not be described in detail.
