Description

Technical Field

[0001] This utility model relates to the field of hydrogen production technology, and more specifically, to a natural gas desulfurization device for hydrogen production. Background Technology

[0002] Natural gas is a common raw material in hydrogen production. However, natural gas usually contains sulfides, which can cause many problems. Therefore, desulfurization equipment is used to desulfurize the natural gas. When the desulfurization tower is working, natural gas enters from the bottom of the tower, and the chemical absorbent is sprayed down from the top of the tower. The natural gas and the absorbent come into full contact inside the tower, and the sulfides are absorbed by the absorbent. The inside of the desulfurization tower is usually filled with packing materials, such as Pall rings, Raschig rings, or tower plates, to increase the gas-liquid contact area and improve the absorption efficiency. After being absorbed and desulfurized by the desulfurization tower, the natural gas is discharged from the desulfurization tower through the gas pipe at the top of the tower and guided to the subsequent processing equipment. Since the gas pipe at the top of the tower is generally outdoors, it is necessary to protect the tower gas pipe during operation.

[0003] In related technologies, during the use of desulfurization towers, the desulfurization tower and the gas pipe are generally connected by flanges and bolts to install and connect the gas pipe and the desulfurization tower for use.

[0004] However, during the current use of desulfurization towers, since the gas pipes are located at the top of the desulfurization tower and operate outdoors, after the gas pipes are installed with flanges and bolts, the connection between the desulfurization tower and the gas pipes is easily corroded and loosened due to the influence of the external environment and dirt, and even natural gas leakage may occur at the connection, affecting the stability and safety of the gas supply to the desulfurization tower.

The connector 2 and the gas pipe 3 can be covered and protected after connection, so as to prevent corrosion and loosening due to external environment and dirt after the connector 2 and the gas pipe 3 are connected, or even natural gas leakage at the connection between the gas pipe 3 and the connector 2. Therefore, the stability and safety of the gas connection of the tower body 1 are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the connecting protective mechanism includes a protective cover 4, which is movably connected to the rear side of the connector 2. A movable cover 5 is movably connected to the front side of the protective cover 4. Protective pads 6 are fixedly connected to both sides of the inner walls of the protective cover 4 and the movable cover 5. A fixed plate 7 is fixedly connected to both sides of the protective cover 4. Movable plates 8 located in front of the fixed plate 7 are fixedly connected to both sides of the movable cover 5. The protective connecting mechanism is located in front of the movable plate 8. By holding the movable cover 5 and the protective cover 4 respectively, the protective pads 6 are moved, covering the outside of the connection between the connector 2 and the air pipe 3. At this time, the inner side of the protective pad 6 contacts the outer side of the air pipe 3 and the connector 2 respectively, performing a sealing operation between the protective cover 4 and the movable cover 5 and the air pipe 3 and the connector 2, and through the fixed plate... 7 and the movable plate 8 form a closed connection between the protective cover 4 and the movable cover 5, so that the protective cover 4 and the movable cover 5, together with the protective pad 6, cover and protect the connection between the air pipe 3 and the connector 2.

Therefore, the closed connection effect of the movable plate 8 and the fixed plate 7 is improved.

[0032] Reference Figures 2-4In a preferred embodiment, by providing separation openings 12 at the top and bottom of the inner wall of the connecting hole 9, and by fixing sealing strips 13 to both sides of the inner side of the protective cover 4 and the movable cover 5, the connecting frame 11 can be provided with installation space to penetrate the movable plate 8. At the same time, the sealing strips 13 seal the protective cover 4 and the movable cover 5 after they are closed, avoiding the situation where the connecting frame 11 is difficult to penetrate the movable plate 8 or the protective cover 4 and the movable cover 5 are difficult to close and seal. Therefore, the operation convenience of the connecting frame 11 and the closing effect of the protective cover 4 and the movable cover 5 are improved. The front side of the connecting column 10 is provided with a movable groove 14, and the movable seat 15 is magnetically connected inside the movable groove 14.

[0033] Reference Figures 2-4 In a preferred embodiment, support openings 16 are provided at the top and bottom of the front side of the movable plate 8. A support column 17 is movably connected inside the support opening 16. The rear side of the support column 17 is fixedly connected to the front side of the fixed plate 7.

Reinforcing seats 22 are fixedly connected to both sides of the outer sides of the movable plate 8 and the fixed plate 7. The inner sides of the reinforcing seats 22 are fixedly connected to the movable cover 5 and the protective cover 4, respectively. This allows for reinforcement of the connection between the fixed plate 7 and the movable plate 8, and between the protective cover 4 and the movable cover 5, ensuring the working stability of the fixed plate 7 and the movable plate 8.

[0035] Specifically, the working process or principle of this natural gas desulfurization device for hydrogen production is as follows: During use, the connecting frame 11 is rotated parallel to the movable plate 8 to prepare for the subsequent passage of the connecting frame 11 through the separation port 12 through the movable plate 8. Then, the movable cover 5 and protective cover 4 are held separately to move the protective pad 6, covering the outside of the connection between the connector 2 and the gas pipe 3. At this time, the inner side of the protective pad 6 contacts the outer side of the gas pipe 3 and the connector 2, respectively, sealing the connection between the protective cover 4 and the movable cover 5, and between the gas pipe 3 and the connector 2. It is important to note that when the protective cover 4 and the movable cover 5 cover the outside of the connector 2 and the gas pipe 3, they should be aligned. At this time, the sealing strips 13 contact each other, closing and sealing the connection between the protective cover 4 and the movable cover 5. Simultaneously, the connecting frame 11 passes through the separation port 12 and the connecting hole 9 through the movable plate 8. Then, the support column 17 passes through the support port 16 through the movable plate 8, and the fixed plate 7 cooperates with the movable plate 8. Install support to prevent displacement between the protective cover 4 and the movable cover 5. Then, move the hand-held card holder 19 outward to extend it out of the card cavity 18 and make contact with the front side of the movable plate 8. Perform a blocking and positioning operation between the movable plate 8 and the fixed plate 7. At this time, the magnetic strip 21 moves with the card holder 19 and cooperates with the magnetic strip 20 to perform magnetic positioning between the card holder 19 and the card cavity 18. Then, rotate the hand-held connecting frame 11 to separate it from the separation port 12. Position the movable plate 8 and the fixed plate 7 through the connecting column 10. At this time, the movable seat 15 rotates with the connecting frame 11 inside the movable groove 14 to perform rotational connection and magnetic positioning between the connecting frame 11 and the connecting column 10. This causes the fixed plate 7 and the movable plate 8 to close and fix the protective cover 4 and the movable cover 5. The protective cover 4 and the movable cover 5, together with the protective pad 6 and the sealing strip 13, cover and protect the connection between the gas pipe 3 and the connector 2, ensuring the connection stability between the connector 2 and the gas pipe 3 and the sealing of the gas pipe 3 for natural gas guidance.

[0036] It should be noted that the tower body 1, connector 2 and air pipe 3 are 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.
