Description

Technical Field

[0001] This invention relates to the field of gas adsorption, and more specifically to a distributed pressurized adsorption reactor. Background Technology

[0002] Due to its advantages such as simple process, low energy consumption, and low cost, adsorption has become one of the most mature and widely used technologies in the field of gas separation and recovery. Besides manufacturing processes and operating conditions, the efficiency and economy of the adsorption process usually depend on the characteristics of the adsorbent. Furthermore, since the adsorbent material is typically a porous medium, and the gas passes through in a seepage manner, it is usually necessary to use methods such as pressurization or suction to increase the seepage driving force.

[0003] However, as the adsorption process proceeds, the adsorbent at the inlet gradually becomes saturated, and its pore structure and surface properties undergo significant changes, leading to increased gas-solid phase resistance, reduced pore size, and other conditions unfavorable to gas permeation. Therefore, it is necessary to elucidate the mechanism of permeation resistance change in the adsorbent material, improve the process and equipment, and propose methods for permeation enhancement and driving force compensation.

[0004] Current efforts to enhance the adsorption process mainly focus on increasing the specific surface area of ​​adsorbent materials, enhancing the selectivity of surface groups, expanding adsorption capacity, improving the antioxidant and corrosion-resistant properties of adsorbent materials, and reducing adsorption and desorption energy consumption. These efforts aim to enhance the gas adsorption process by improving the adsorption performance of adsorbent materials. However, there are few approaches to enhance the gas adsorption process by changing the pore characteristics, assembly form, or gas-solid phase resistance of the material. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem of insufficient gas adsorption efficiency in existing technologies.

[0006] To achieve the above objectives, the present invention provides a distributed pressurized adsorption reactor, wherein the distributed pressurized adsorption reactor includes a tubular shell, at least one tubular partition disposed in the shell, a first sealing plug disposed at a first end of the shell, and a second sealing plug disposed at a second end of the shell. The partition divides the shell to form at least two filling cavities arranged radially from the inside to the outside. The at least two filling cavities are capable of being filled with solid adsorbent materials of different particle sizes, wherein the particle size of the solid adsorbent materials increases radially outward. The first sealing plug is provided with an air inlet communicating with each of the filling cavities, and the second sealing plug is provided with an air outlet communicating with each of the filling cavities.

[0007] In some embodiments, the first sealing plug includes a first end cap and a first screen. The surface of the first end cap facing the housing has a recess. The first screen is connected to the surface of the first end cap facing the housing to form a first dispersion cavity. The first dispersion cavity is connected to the air inlet and each of the filling cavities.

[0008] In some embodiments, the second sealing plug includes a second end cap and a second screen. The surface of the second end cap facing the housing has a recess, and the second screen is connected to the surface of the second end cap facing the housing to form a second dispersion cavity.

[0012] In some embodiments, the inner diameter of the large end of the housing is 2-5 times the inner diameter of the small end, and the cone angle of the housing is 18°-22°.

[0013] In some embodiments, the inner diameter of the air inlet is 0.03-0.1 times the inner diameter of the large end of the housing, and the length of the first dispersion cavity is 0.1-0.2 times the inner diameter of the large end of the housing.

[0015] In some embodiments, the inner diameter of the air outlet is 0.02-0.05 times the inner diameter of the small end of the housing, and the length of the second dispersion cavity is 0.05-0.1 times the inner diameter of the small end of the housing.

[0016] In some embodiments, the second screen has a mesh size greater than 40 and less than 80.

[0017] In some embodiments, the distributed pressurized adsorption reactor is provided with only one partition, and the inner diameter of the large end of the partition is 0.4-0.6 times the inner diameter of the large end of the shell.

[0018] In some embodiments, the distributed pressurized adsorption reactor is provided with only two of the aforementioned separators, the innermost inner diameter of the inner separator being 0.25-0.33 times the innermost inner diameter of the shell, and the outermost inner diameter of the separator being 0.55-0.67 times the innermost inner diameter of the shell.

[0019] In some embodiments, the distributed pressurized adsorption reactor includes a first connecting pipe disposed at a first end of the shell and a second connecting pipe disposed at a second end of the shell, wherein a first sealing plug is disposed in the first connecting pipe and a second sealing plug is disposed in the second connecting pipe.

[0020] In some embodiments, the separator is connected to the housing via a connecting rod.

[0021] The above technical solution optimizes the gas permeation channel, promotes the full dispersion of gas in the adsorption material, and allows the gas to be adsorbed to be distributed more evenly in the radial direction. This strengthens the gas permeation process, realizes the permeation and kinetic energy enhancement of the adsorption process, and improves the adsorption efficiency. Attached Figure Description

[0032] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] Example 1

[0034] refer to Figure 1As shown, this solution provides a distributed pressurized adsorption reactor, wherein the distributed pressurized adsorption reactor includes a tubular shell 1, at least one tubular partition 2 disposed in the shell 1, a first sealing plug 3 disposed at a first end of the shell 1, and a second sealing plug 7 disposed at a second end of the shell 1. The partition 2 divides the shell 1 to form at least two filling cavities arranged radially from the inside to the outside. The at least two filling cavities can be filled with solid adsorbent materials of different particle sizes respectively. The particle size of the solid adsorbent materials increases in the radial direction. The first sealing plug 3 is provided with an air inlet 11 communicating with each filling cavity, and the second sealing plug 7 is provided with an air outlet 12 communicating with each filling cavity.

[0035] The housing 1 has a first sealing plug 3 and a second sealing plug 7 at both ends, forming a receiving space. A tubular partition 2 is disposed within the housing 1 and located within this receiving space. If only one partition 2 is provided, it divides the receiving space into two filling cavities. If two or more partitions 2 are provided, these partitions 2 are nested sequentially, thereby dividing the receiving space into more filling cavities. The partition 2 has no through holes, and adjacent filling cavities cannot be connected through the partition 2.

[0036] In the radial direction from the inside out, at least two filling cavities are arranged in sequence, and the particle size of the solid adsorbent material filled in them increases sequentially. That is, in any two adjacent filling cavities, the particle size of the solid adsorbent material in the radially inner filling cavity is smaller than the particle size of the solid adsorbent material in the radially outer filling cavity. Therefore, in the radial direction from the inside out, the pore size in the filling cavities increases sequentially, and its resistance to gas decreases sequentially.

[0037] The air inlet 11 is synchronously connected to each filling chamber, allowing the gas to be distributed to each filling chamber in a specific proportion based on the resistance in different filling chambers.

[0038] In ordinary adsorption chambers, gas tends to converge near the central axis of the chamber and move away from the edge. However, in this design, the pore size and porosity of the radially outer filling chamber are larger, resulting in less resistance to gas. This allows the gas to be distributed more evenly throughout the space in the radial direction, increasing the gas permeability in the solid adsorption material, enhancing the permeation and kinetic energy of the adsorption process, and improving adsorption efficiency.

[0039] In this scheme, the gas permeation channel is optimized to promote the full dispersion of gas in the adsorbent material. The gas to be adsorbed can be more evenly distributed in the radial direction, which enhances the gas permeation process, realizes the permeation and kinetic energy enhancement of the adsorption process, and improves the adsorption efficiency.

[0040] The first sealing plug 3 includes a first end cap 4 and a first screen 5. The first end cap 4 has a recessed portion on its surface facing the housing 1. The first screen 5 is connected to the surface of the first end cap 4 facing the housing 1 to form a first dispersion cavity 13. The first dispersion cavity 13 is connected to the air inlet 11 and each of the filling cavities. The first end cap 4 and the first screen 5 enclose the first dispersion cavity 13. Gas entering the first dispersion cavity 13 through the air inlet 11 is fully dispersed radially and passes through the first screen 5 into each filling cavity. The end of the separator 2 is engaged with the first screen 5, thereby separating the filling cavities from each other and preventing leakage of the solid adsorbent material. In other embodiments, the first sealing plug 3 may form a main pipeline connected to the air inlet 11 and branch pipelines connected to each filling cavity, with the main pipeline and branch pipelines interconnected. A detachable connector may be provided on the first end cap 4, and the air inlet 11 is provided in the connector.

[0041] Similarly, the second sealing plug 7 includes a second end cap 8 and a second screen 9. The second end cap 8 has a recessed portion on its surface facing the housing 1. The second screen 9 is connected to the surface of the second end cap 8 facing the housing 1 to form a second dispersion cavity 14. The second dispersion cavity 14 is connected to the air outlet 12 and each of the filling cavities. The second end cap 8 and the second screen 9 enclose the second dispersion cavity 14. Gas in each filling cavity passes through the second screen 9 into the second dispersion cavity 14 and is then discharged through the air outlet 12. The end of the separator 2 is engaged with the second screen 9, thereby separating the filling cavities from each other and preventing leakage of the solid adsorbent material therein. In other embodiments, the second sealing plug 7 may form a main pipeline connected to the air outlet 12 and branch pipelines connected to each filling cavity, with the main pipeline and branch pipelines connected to each other. A detachable connector may be provided on the second end cap 8, with the air outlet 12 provided in the connector.

(Reference) Figure 1 As shown, the left end of the shell 1 is the large end and the right end is the small end, and the left end of the separator 2 is the large end and the right end is the small end. The shell 1 is formed into a tapered tube, which can achieve the following: reduce the pressure difference between the inlet and outlet ends, and improve the gas permeation capacity; expand the gas sweep volume in the adsorption reactor, and improve the adsorbent saturation rate; increase the outlet gas pressure, and achieve gas kinetic energy enhancement.

[0043] Furthermore, the housing 1 and the partition 2 are coaxially arranged. The coaxial arrangement of the central axes of the housing 1 and the partition 2 makes each filling cavity form a centrally symmetrical structure, which facilitates a more uniform radial distribution of gas.

[0044] The housing 1 and the partition 2 have the same cone angle.

[0045] Optionally, the inner diameter of the larger end of the housing 1 is twice the inner diameter of the smaller end, and the cone angle of the housing 1 is 18°-22°. The inner diameter of the larger end of the housing 1 does not exceed 30cm.

[0046] Optionally, the inner diameter of the air inlet 11 is 0.03-0.1 times the inner diameter of the larger end of the housing 1, and the length of the first dispersion cavity 13 is 0.1-0.2 times the inner diameter of the larger end of the housing 1.

[0047] Optionally, the mesh count of the first screen 5 is greater than or equal to 80 mesh.

[0048] The inner diameter of the air outlet 12 is 0.02-0.05 times the inner diameter of the small end of the housing 1, and the length of the second dispersion cavity 14 is 0.05-0.1 times the inner diameter of the small end of the housing 1.

[0049] The second screen 9 has a mesh size greater than 40 and less than 80 to reduce the kinetic energy loss of the gas at the outlet.

[0050] In some embodiments, the distributed pressurized adsorption reactor is provided with only one partition 2, and the inner diameter of the larger end of the partition 2 is 0.4-0.6 times the inner diameter of the larger end of the shell 1.

[0051] In other embodiments, the distributed pressurized adsorption reactor is provided with only two of the aforementioned separators 2, with the inner diameter of the larger end of the inner separator 2 being 0.25-0.33 times the inner diameter of the larger end of the shell 1, and the inner diameter of the larger end of the outer separator 2 being 0.55-0.67 times the inner diameter of the larger end of the shell 1.

[0052] Additionally, the distributed pressurized adsorption reactor includes a first connecting pipe 6 disposed at the first end of the shell 1 and a second connecting pipe 10 disposed at the second end of the shell 1. A first sealing plug 3 is disposed in the first connecting pipe 6, and a second sealing plug 7 is disposed in the second connecting pipe 10. The first connecting pipe 6 can be welded (or screwed) to the first end of the shell 1. The first sealing plug 3 is accommodated in the first connecting pipe 6, and a sealing ring can be provided on the outer periphery of the first sealing plug 3 and / or the inner periphery of the first connecting pipe 6 to improve the sealing effect. The second connecting pipe 10 can be welded (or screwed) to the second end of the shell 1. The second sealing plug 7 is accommodated in the second connecting pipe 10, and a sealing ring can be provided on the outer periphery of the second sealing plug 7 and / or the inner periphery of the second connecting pipe 10 to improve the sealing effect.

[0053] In addition, the partition 2 is connected to the housing 1 via a connecting rod 15. The connecting rod 15 can extend in the radial direction, the partition 2 is connected to the connecting rod 15, and the radially outer end of the connecting rod 15 is connected to the inner surface of the housing 1, thereby achieving a fixed connection between the partition 2 and the housing 1.

[0054] Example 2

The partition 2 divides the shell 1 to form at least two filling cavities arranged radially from the inside to the outside. The at least two filling cavities can be filled with solid adsorbent materials of different particle sizes respectively. The particle size of the solid adsorbent materials increases in the radial direction. The first sealing plug 3 is provided with an air inlet 11 communicating with each filling cavity, and the second sealing plug 7 is provided with an air outlet 12 communicating with each filling cavity.

[0056] The housing 1 has a first sealing plug 3 and a second sealing plug 7 at both ends, forming a receiving space. A tubular partition 2 is disposed within the housing 1 and located within this receiving space. If only one partition 2 is provided, it divides the receiving space into two filling cavities. If two or more partitions 2 are provided, these partitions 2 are nested sequentially, thereby dividing the receiving space into more filling cavities. The partition 2 has no through holes, and adjacent filling cavities cannot be connected through the partition 2.

[0057] In the radial direction from the inside out, at least two filling cavities are arranged in sequence, and the particle size of the solid adsorbent material filled in them increases sequentially. That is, in any two adjacent filling cavities, the particle size of the solid adsorbent material in the radially inner filling cavity is smaller than the particle size of the solid adsorbent material in the radially outer filling cavity. Therefore, in the radial direction from the inside out, the pore size in the filling cavities increases sequentially, and its resistance to gas decreases sequentially.

[0058] The air inlet 11 is synchronously connected to each filling chamber, allowing the gas to be distributed to each filling chamber in a specific proportion based on the resistance in different filling chambers.

[0059] In ordinary adsorption chambers, gas tends to converge near the central axis of the chamber and move away from the edge. However, in this design, the pore size and porosity of the radially outer filling chamber are larger, resulting in less resistance to gas. This allows the gas to be distributed more evenly throughout the space in the radial direction, increasing the gas permeability in the solid adsorption material, enhancing the permeation and kinetic energy of the adsorption process, and improving adsorption efficiency.

[0060] In this scheme, the gas permeation channel is optimized to promote the full dispersion of gas in the adsorbent material. The gas to be adsorbed can be more evenly distributed in the radial direction, which enhances the gas permeation process, realizes the permeation and kinetic energy enhancement of the adsorption process, and improves the adsorption efficiency.

[0061] The first sealing plug 3 includes a first end cap 4 and a first screen 5. The first end cap 4 has a recessed portion on its surface facing the housing 1. The first screen 5 is connected to the surface of the first end cap 4 facing the housing 1 to form a first dispersion cavity 13. The first dispersion cavity 13 is connected to the air inlet 11 and each of the filling cavities. The first end cap 4 and the first screen 5 enclose the first dispersion cavity 13. Gas entering the first dispersion cavity 13 through the air inlet 11 is fully dispersed radially and passes through the first screen 5 into each filling cavity. The end of the separator 2 is engaged with the first screen 5, thereby separating the filling cavities from each other and preventing leakage of the solid adsorbent material. In other embodiments, the first sealing plug 3 may form a main pipeline connected to the air inlet 11 and branch pipelines connected to each filling cavity, with the main pipeline and branch pipelines interconnected. A detachable connector may be provided on the first end cap 4, and the air inlet 11 is provided in the connector.

The second screen 9 is connected to the surface of the second end cap 8 facing the housing 1 to form a second dispersion cavity 14. The second dispersion cavity 14 is connected to the air outlet 12 and each of the filling cavities. The second end cap 8 and the second screen 9 enclose the second dispersion cavity 14. Gas in each filling cavity passes through the second screen 9 into the second dispersion cavity 14 and is then discharged through the air outlet 12. The end of the separator 2 is engaged with the second screen 9, thereby separating the filling cavities from each other and preventing leakage of the solid adsorbent material therein. In other embodiments, the second sealing plug 7 may form a main pipeline connected to the air outlet 12 and branch pipelines connected to each filling cavity, with the main pipeline and branch pipelines connected to each other. A detachable connector may be provided on the second end cap 8, with the air outlet 12 provided in the connector.

[0096] This solution provides a distributed pressurized adsorption reactor. The multi-layered, tapering filling chambers enable distributed loading of adsorbent materials with different particle sizes, and enhance permeation and kinetic energy during the adsorption process. The sealing plugs are divided into large-mouth and small-mouth sealing plugs to facilitate gas injection / exhaust and dispersion, as well as adsorbent material compaction. By constraining the dimensional proportions of the shell, separators, end openings, and gas inlet / outlet components, distributed loading of the adsorbent material is achieved, fully leveraging the enhanced gas adsorption and permeation processes. Gas dispersion chambers are incorporated within the end sealing plugs to disperse the gas at the inlet, increasing the contact area between the gas and the adsorbent material while simultaneously reducing kinetic energy loss at the outlet, thus enhancing gas permeation capacity.

[0097] Under the same capacity, the distributed pressurized adsorption reactor provided by this scheme has the following positive effects:

[0098] (1) Reduce the pressure difference between the inlet and outlet ends to improve gas permeability;

[0099] (2) Increase the gas sweep volume in the adsorption chamber and improve the adsorbent saturation rate;

[0100] (3) Increase the outlet gas pressure to enhance the gas kinetic energy.

[0101] Based on the results of previous tests, under the conditions of the same gas, the same gas volume, the same reaction chamber volume, and the same adsorbent material, this device reduces the inlet and outlet pressure drop by more than 27% and increases the saturated adsorption capacity of the adsorbent material by more than 13% compared with the hollow cylindrical adsorption tube, showing a significant performance improvement.
