Description

Technical Field

[0001] This utility model belongs to the field of hydrogen deoxygenation technology, specifically relating to a vertical hydrogen deoxygenation device. Background Technology

[0002] In the hydrogen purification process, hydrogen deoxygenation is usually required. Traditional hydrogen deoxygenation devices are horizontal structures, but horizontal devices occupy a large area and can lead to uneven gas flow distribution. Therefore, vertical deoxygenation devices are now more commonly used. However, existing vertical deoxygenation devices have a relatively complex structure, and the catalyst particles in existing deoxygenation devices are easily pulverized or dented under the impact of gas, resulting in incomplete catalytic deoxygenation reaction and incomplete hydrogen deoxygenation. At the same time, pulverized particulate impurities are easily carried out from the gas outlet, requiring further filtration, which increases the number of purification steps and raises production costs. Utility Model Content

[0003] The purpose of this utility model is to provide a vertical hydrogen deoxygenation device. An inlet mesh assembly and an outlet mesh assembly are installed inside the housing. A 15cm thick first ceramic ball is laid flat between the first and second wire meshes below the first grid plate of the inlet mesh assembly to resist gas impact and prevent catalyst particles from denting or pulverizing. A 10cm thick second ceramic ball is laid flat between the third and fourth wire meshes above the second grid plate at the bottom of the housing. The diameter of the second ceramic ball is smaller than that of the first ceramic ball, preventing impurities in the catalyst particles from falling from the outlet. Furthermore, the thickness of the second ceramic ball is less than that of the first ceramic ball, making the gas outlet process smoother.

[0004] This utility model is achieved through the following technical solution:

[0005] A vertical hydrogen deoxygenation device includes a shell, an inlet mesh assembly, and an outlet mesh assembly. Both the inlet mesh assembly and the outlet mesh assembly are disposed within the shell, spaced vertically apart. The inlet mesh assembly is located at the upper part of the shell, and the outlet mesh assembly is located at the lower part. Catalyst particles are filled between the inlet mesh assembly and the outlet mesh assembly. An inlet is provided at the top of the shell, and an outlet is provided at the bottom of the shell, with the inlet and outlet communicating with each other. Multiple temperature measuring ports are distributed from top to bottom on the side of the shell between the inlet mesh assembly and the outlet mesh assembly.

[0006] Preferably, the air intake mesh assembly includes a first grille plate, a first wire mesh, a second wire mesh, and a plurality of first ceramic balls, wherein the first ceramic balls are disposed between the first wire mesh and the second wire mesh, and the grille plate is disposed above the second wire mesh.

[0007] Preferably, the first wire mesh has a diameter of 14 mesh and the second wire mesh has a diameter of 4 mesh.

[0008] Preferably, the diameter of the first ceramic ball is 10 mm, and the thickness of the first ceramic ball laid between the first wire mesh and the second wire mesh is 15 cm.

[0009] Preferably, the air outlet mesh assembly includes a second grid plate, a third wire mesh, a fourth wire mesh, and a plurality of second ceramic balls. The inner sidewall of the housing is provided with support members around the perimeter below the second grid plate. The support members are used to support the grid plate. The third wire mesh is disposed above the fourth wire mesh, and the second ceramic balls are disposed between the third wire mesh and the fourth wire mesh.

[0010] Preferably, the third wire mesh has a mesh size of 14 and the fourth wire mesh has a mesh size of 4.

[0011] Preferably, the diameter of the second ceramic ball is 9 mm, and the thickness of the second ceramic ball between the third and fourth wire meshes is 10 cm.

[0013] Preferably, a feeding port is provided on the side wall of the housing above the air inlet mesh assembly.

[0014] Preferably, a discharge port is provided on the side of the housing above the air outlet assembly.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] 1) In this utility model, by setting an air inlet mesh assembly and an air outlet mesh assembly inside the housing, a 15cm thick first ceramic ball is laid flat between the first wire mesh and the second wire mesh below the first grid plate of the air inlet mesh assembly to resist the impact of gas and prevent the catalyst particles from being dented or pulverized. A 10cm thick second ceramic ball is laid flat between the third wire mesh and the fourth wire mesh above the second grid plate at the bottom of the housing. The diameter of the second ceramic ball is smaller than that of the first ceramic ball, which can prevent impurities in the catalyst particles from falling from the air outlet. At the same time, the thickness of the second ceramic ball is smaller than that of the first ceramic ball, making the air outlet process smoother.

[0017] 2) In this utility model, three temperature measuring ports are provided on the side wall of the shell. Insertion temperature sensors are provided in the temperature measuring ports, which can monitor the temperature changes at the top, middle and bottom positions of the catalyst particles. The temperature is high when the gas first enters, and the temperature gradually decreases as the reaction moves downward. If the reaction temperature of the catalyst is lower than the range value, it indicates that the catalyst can be replaced, thereby further ensuring the purity requirements of hydrogen.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] Example 1:

[0026] A vertical hydrogen deoxygenation device, such as Figure 1 and Figure 4As shown, the system includes a housing 1, an inlet mesh assembly 3, and an outlet mesh assembly 4. The housing 1 is a vertical cylindrical structure with a diameter of 1.4 m. A support frame 2 is provided at the bottom of the housing 1 to support the housing 1 and keep it upright. Both the inlet mesh assembly 3 and the outlet mesh assembly 4 are located inside the housing 1, spaced vertically. The inlet mesh assembly 3 is located at the upper part of the housing 1, and the outlet mesh assembly 4 is located at the lower part of the housing 1. Catalyst particles are filled between the inlet mesh assembly 3 and the outlet mesh assembly 4. Multiple support members 5 are provided below the outlet mesh assembly 4 to support the outlet mesh assembly 4 and space it from the bottom of the housing 1. An inlet 11 is provided at the top of the housing 1, and an outlet 12 is provided at the bottom of the housing 1. The inlet 11 and the outlet 12 are connected. The mixed gas enters the housing 1 through the inlet 11, and after being filtered by the inlet mesh assembly 3 to remove impurities, it enters the catalyst particles. The deoxygenation reaction is carried out, and the purified hydrogen gas is discharged from the outlet 12 at the bottom of the shell 1. During this process, the mixed gas is continuously input into the shell 1, so that the hydrogen gas can flow out from the outlet 12 at the bottom of the shell 1. There are three temperature measuring ports 15 distributed from top to bottom on the side of the shell 1 between the inlet mesh assembly 3 and the outlet mesh assembly 4. The temperature measuring ports 15 are used to install insertion temperature sensors. The temperature sensors can monitor the temperature changes at the top, middle and bottom of the catalyst particle stack. The temperature is high when the gas first enters, and the temperature gradually decreases as the reaction moves downward. If the reaction temperature of the catalyst is lower than the range value, it indicates that the catalyst can be replaced, so as to further ensure the purity requirements of the hydrogen gas. A feeding port 13 is provided on the side wall of the housing 1 above the air inlet mesh assembly 3, and a discharge port 14 is provided on the side of the housing 1 above the air outlet mesh assembly 4. Before adding the catalyst particles, first install the air outlet mesh assembly 4 from the discharge port 14, then pour the catalyst particles into the feeding port 13, and finally lay the air inlet mesh assembly 3 on the catalyst particles from the feeding port 13.

[0027] Example 2:

[0028] This embodiment, based on the above embodiment, further defines the air intake mesh assembly 3, such as... Figure 1 and Figure 2As shown, the air intake mesh assembly 3 includes a first grid plate 31, a first wire mesh 32, a second wire mesh 34, and a plurality of first ceramic balls 33. The first ceramic balls 33 are disposed between the first wire mesh 32 and the second wire mesh 34, and the grid plate is disposed above the second wire mesh 34. The air intake mesh assembly 3 is laid above the catalyst particles. The first wire mesh 32 abuts against the catalyst particles. The space between the first wire mesh 32 and the second wire mesh 34 is filled with first ceramic balls 33 with a thickness of 15 cm and a diameter of 10 mm. The first wire mesh 32 has a mesh size of 14 meshes and a wire diameter of 0.46 mm; the second wire mesh 34 has a mesh size of 4 meshes and a wire diameter of 1.13 mm. The first grid plate 31 adopts a centrally hinged or multi-segment folding structure, allowing it to be inserted into the housing 1 through the feeding port 13 for laying. Other parts of this embodiment are the same as those in the above embodiment and will not be described again here.

[0029] Example 3:

[0030] This embodiment, based on the above embodiment, further defines the air outlet mesh assembly 4, such as... Figure 1 and Figure 3 As shown, the air outlet mesh assembly 4 includes a second grille plate 41, a third wire mesh 42, a fourth wire mesh 44, and several second ceramic balls 43. Support members 5 are arranged around the inner wall of the housing 1 below the second grille plate 41. The second grille plate 41 is located at the bottom of the housing 1 and abuts against the support members 5 inside the housing 1. The support members 5 support the grille plate. The third wire mesh 42 is located above the fourth wire mesh 44, and the second ceramic balls 43 are located between the third wire mesh 42 and the fourth wire mesh 44. The diameter of the second ceramic balls 43 is 9mm, and the thickness of the second ceramic balls 43 is 10cm. The third wire mesh 42 has a mesh size of 14 and a wire diameter of 0.46mm, while the fourth wire mesh 44 has a mesh size of 4 and a wire diameter of 1.13mm. The diameter and thickness of the second ceramic ball 43 in the outlet mesh assembly 4 are smaller than those of the first ceramic ball 33 in the inlet mesh assembly 3. Since the first ceramic ball 33 in the inlet mesh assembly 3 is used to resist the impact of gas and prevent catalyst particles from being dented or pulverized, its thickness is greater. The diameter of the second ceramic ball 43 is smaller, and the gaps between the balls are also smaller. This prevents impurities in the catalyst particles from falling from the outlet 12. Furthermore, the thinner thickness of the second ceramic ball 43 makes the gas outlet process smoother. Other parts of this embodiment are the same as those in the above embodiments and will not be repeated here.
