Description

Technical Field

[0001] This invention relates to the field of gas purification technology, and in particular to an adsorber and an adsorption system. Background Technology

[0002] Adsorbers are a commonly used device for gas purification. Molecular sieves are filled in the adsorber. The material enters the adsorber from the feed port and passes through the molecular sieve. The molecular sieve can adsorb and remove impurities in the material. After the material is adsorbed and impurities are removed, it is discharged from the discharge pipe.

[0003] The adsorber is mainly a straight cylindrical structure. Currently, the interior of the adsorber is filled with molecular sieves between the upper and lower partitions. As a result, the material gas usually flows to the part that is easier to flow, causing uneven airflow distribution. This results in some molecular sieves being saturated while others are not fully utilized. This affects the adsorption efficiency and wastes the molecular sieves, thus affecting their service life. Summary of the Invention

[0004] The main objective of this invention is to propose an adsorber and adsorption system that aims to solve the technical problems of uneven distribution of airflow and insufficient utilization of molecular sieves in the prior art.

[0005] To achieve the above objectives, the present invention proposes an adsorber, comprising an outer cylinder and a distributor. A discharge pipe is provided on the upper side of the outer cylinder. The distributor is located on the lower inner side of the outer cylinder. The distributor includes an outer basket and a middle basket arranged in a ring shape. The outer basket is located around the outer periphery of the middle basket. A first air passage is provided between the outer wall of the outer basket and the inner wall of the outer cylinder. A first baffle is provided outwardly on the upper side of the outer basket, located above the first air passage. A second air passage is provided between the inner wall of the outer basket and the outer wall of the middle basket. The outer basket has a second baffle between its upper side and the upper side of the middle basket. The second baffle is located on the upper side of the second air passage. The first air passage has a feed hole that communicates with the first air passage. The outer basket has an air passage that communicates with the first air passage and the second air passage. The side wall of the middle basket has a plurality of first ventilation holes that communicate with the second air passage and the inner side of the middle basket. The inner side of the middle basket and the inner side of the outer cylinder can be filled with molecular sieves. The material to be adsorbed can first enter the first air passage through the feed hole, then enter the second air passage through the air passage, and then enter the inner side of the middle basket and the inner side of the outer cylinder through the first air vent. After being adsorbed by the molecular sieve, it is finally discharged from the discharge pipe.

[0006] A distributor is installed on the lower inner side of the outer cylinder. Molecular sieves are filled in the inner side of the middle basket of the distributor and the space located on the upper side of the distributor in the outer cylinder. The material to be adsorbed enters the first air passage through the feed hole to buffer and slow down the material speed. Then it enters the second air passage through the air hole, and then enters the inner side of the middle basket and the inner side of the outer cylinder through multiple first air holes on the middle basket. This can disperse the material more evenly and make the material more evenly dispersed to the molecular sieves at different positions. After being adsorbed by the molecular sieves, the material is discharged from the discharge pipe on the upper side of the outer cylinder.

[0007] This adsorber is equipped with a distributor. The material is first buffered and dispersed in the distributor before being adsorbed, which makes the material contact the molecular sieves at different positions in the outer cylinder more evenly. This allows the molecular sieves to be used more fully, improves the adsorption effect, reduces waste of molecular sieves, and extends service life.

[0008] Preferably, the distributor further includes an annular inner basket located inside the middle basket. A third baffle is provided between the lower side of the inner basket and the lower side of the middle basket, and a fourth baffle is provided on the inner side of the upper side of the inner basket. The second air passage extends to the inner side of the inner basket, and a plurality of second vent holes are provided on the side wall of the inner basket. The second vent holes connect the inner side of the inner basket and the inner side of the middle basket, and molecular sieves can be filled between the outer side of the inner basket and the inner side of the middle basket. After entering the second air passage, the material can flow from the lower side of the second air passage to the inner side of the inner basket, and then enter the inner side of the middle basket through the second air hole.

[0009] An inner basket is also provided inside the middle basket. Molecular sieves are filled between the outer side of the inner basket and the inner side of the middle basket. After the material enters the second air passage, it can flow downward to the inner side of the inner basket in addition to entering the inner side of the middle basket through the first air hole, and then enter the inner side of the middle basket through the second air hole. This allows the material to enter the molecular sieve in the middle area for adsorption, further improving the uniformity of material dispersion and increasing the utilization rate of the molecular sieve.

[0010] Preferably, the third baffle is provided with a plurality of third vent holes, and the fourth baffle is provided with a plurality of fourth vent holes. The material can pass through the third vent holes and the fourth vent holes to enter the inner side of the middle basket, which can further increase the contact area between the material and the molecular sieve, improve the uniformity of material dispersion, and improve the utilization rate of the molecular sieve.

[0011] Preferably, the outer circumference of the outer basket is provided with a spiral plate that rises upwards. The groove formed by the spiral plate on the outer circumference of the outer basket is the first air passage. The feed hole is connected to the lower side of the first air passage, and the air passage is located on the upper side of the first air passage and the second air passage.

[0012] A spiral plate is set on the outer periphery of the outer basket to form the first air passage. The material enters the first air passage from the bottom and flows spirally upward along the first air passage to the air passage hole. Then the material flows downward from the second air passage. This has a better buffering effect on the material and makes the subsequent dispersion more uniform.

[0013] Preferably, the adsorber further includes a base, the lower end of the outer cylinder is fixedly connected to the base by a first screw, the lower end of the outer basket is fixedly connected to the base, and the upper end of the middle basket is fixedly connected to the upper end of the outer basket by a second screw.

[0014] This allows the outer cylinder to be separated from the base, and the middle basket to be separated from the outer basket, making it convenient to disassemble and clean the gap between the outer basket and the middle basket, as well as the first vent on the middle basket, after long-term use.

[0015] Preferably, the lower end face of the outer cylinder is provided with a protruding ring, the upper side of the base is provided with a groove, a sealing gasket is provided in the groove, and the protruding ring is inserted into the groove and presses against the sealing gasket; Alternatively, the lower end face of the outer cylinder is provided with a groove, the upper side of the base is provided with a protruding ring, a sealing gasket is provided in the groove, and the protruding ring is inserted into the groove and presses against the sealing gasket.

[0016] The lower end of the outer cylinder and the upper side of the base are provided with a convex ring and a groove for sealing, and a sealing gasket is placed in the groove to improve the sealing performance. It can be used for adsorption of highly toxic, flammable and explosive materials with high purity requirements.

[0017] Preferably, the adsorber further includes a feed pipe, which is fixed to the base and extends upward from the base to the inner side of the outer basket. The feed hole is located on the outer basket, and the end of the feed pipe is fixedly connected to the feed hole.

[0018] The feed pipe extends from the base to the inside of the outer basket and connects to the outer basket. This way, the feed pipe does not need to be disassembled when removing the outer cylinder, making disassembly and assembly more convenient.

[0019] Preferably, the outer cylinder is provided with a plurality of heat-conducting fins, which are located on the upper side of the distributor and extend along the radial and axial directions of the outer cylinder.

[0020] The heat-conducting fins can transfer heat at multiple vertical and radial positions within the outer cylinder, making the temperature inside the outer cylinder more uniform and avoiding excessively high local temperatures and large internal temperature differences, which would affect the adsorption effect.

[0021] Preferably, the adsorber further includes an upper cover, which is disposed on the upper side of the outer cylinder. The outer cylinder and the upper cover are detachably connected. The discharge pipe is disposed on the upper cover. A limiting plate is fixed on the lower side of the upper cover. The limiting plate is disposed on the inner side of the outer cylinder. The limiting plate is provided with a plurality of fifth ventilation holes. The limiting plate is used to limit the height of the molecular sieve on the upper side of the molecular sieve.

[0022] After adsorption, the material flows upward through the fifth vent. The limiting plate on the upper side of the molecular sieve can limit the molecular sieve from exceeding the height of the outer cylinder, and the compacted molecular sieve ensures that the molecular sieve inside the adsorber will not be blown up and down by the airflow.

[0023] In another aspect, the present invention also proposes an adsorption system having at least two of the above-mentioned adsorbers, wherein the at least two adsorbers are arranged in series, and the two adsorbers arranged in series are connected in series by a series pipe, the series pipe extending in a curved shape, and heat dissipation fins are provided on the outer side of the series pipe.

[0024] Setting at least two adsorbers in series allows for multi-stage adsorption, improving purification efficiency. Extending the series piping in a curved shape increases the flow and heat dissipation distance, and installing heat sinks on the piping facilitates heat dissipation from high-temperature materials, further enhancing the adsorber's adsorption capacity.

[0032] like Figures 1 to 6As shown, an adsorber includes an outer cylinder 1 and a distributor 2. A discharge pipe 41 is provided on the upper side of the outer cylinder 1. The distributor 2 is located on the lower inner side of the outer cylinder 1. The distributor 2 includes an outer basket 21 and a middle basket 22, both arranged in a ring shape. The outer basket 21 is located around the outer periphery of the middle basket 22. A first air passage 23 is provided between the outer wall of the outer basket 21 and the inner wall of the outer cylinder 1. A first baffle 211 is provided outwardly on the upper side of the outer basket 21, above the first air passage 23. The inner wall of the outer basket 21 and the middle basket 22 are connected in a ring shape. A second ventilation channel 24 is provided between the outer walls of the middle basket 22 and the outer walls of the middle basket 22. A second baffle 221 is provided between the upper side of the outer basket 21 and the upper side of the middle basket 22. The second baffle 221 is located above the second ventilation channel 24. A first ventilation channel 23 is provided with a feed hole 212, which communicates with the first ventilation channel 23. A ventilation hole 213 is provided on the outer basket 21, which communicates with the first ventilation channel 23 and the second ventilation channel 24. A plurality of first ventilation holes 222 are provided on the side walls of the middle basket 22. (Refer to...) Figure 2 The first vent 222 connects the second air passage 24 with the inner side of the middle basket 22. The inner side of the middle basket 22 and the inner side of the outer cylinder 1 can be filled with molecular sieve. The first baffle 211 and the second baffle 221 can prevent the molecular sieve from entering the first air passage 23 and the second air passage 24. The diameter of the first vent 222 is smaller than the size of the molecular sieve.

[0033] The material to be adsorbed can first enter the first air passage 23 through the feed hole 212, then enter the second air passage 24 through the air passage 213, and then enter the inner side of the middle basket 22 and the inner side of the outer cylinder 1 through the first air vent 222. After being adsorbed by the molecular sieve, it is finally discharged from the discharge pipe 41.

[0034] A distributor 2 is installed on the lower inner side of the outer cylinder 1. Molecular sieves are filled inside the middle basket 22 of the distributor 2 and in the space above the distributor 2 inside the outer cylinder 1, as shown in the figure. Figure 1 The filling area in the middle; the material to be adsorbed enters the first air passage 23 through the feed hole 212 to buffer and slow down the material speed, then enters the second air passage 24 through the air passage 213, and then enters the inner side of the middle basket 22 and the inner side of the outer cylinder 1 through the multiple first air vents 222 on the middle basket 22, as shown in the figure. Figure 2 The schematic diagram of the airflow direction shows that the material can be dispersed more evenly, allowing the material to be more evenly dispersed to the molecular sieves at different locations. After being adsorbed by the molecular sieves, the material is discharged from the discharge pipe 41 on the upper side of the outer cylinder 1.

[0035] This adsorber is equipped with a distributor 2. The material is first buffered and dispersed in the distributor 2 before being adsorbed, so that the material comes into more uniform contact with the molecular sieves at different positions inside the outer cylinder 1, making fuller use of the molecular sieves, improving the adsorption effect, reducing waste of molecular sieves, and extending service life.

[0036] In some specific embodiments, the distributor 2 further includes an annularly arranged inner basket 25, which is located inside the middle basket 22. A third baffle 251 is provided between the lower side of the inner basket 25 and the lower side of the middle basket 22. A fourth baffle 252 is provided on the inner side of the upper side of the inner basket 25. A second air passage 24 extends to the inner side of the inner basket 25. A plurality of second vent holes 253 are arranged on the side wall of the inner basket 25. (Refer to...) Figure 2 The diameter of the second vent 253 is smaller than the size of the molecular sieve. The second vent 253 connects the inner side of the inner basket 25 with the inner side of the middle basket 22. Molecular sieve can be filled between the outer side of the inner basket 25 and the inner side of the middle basket 22. After entering the second air passage 24, the material can flow from the lower side of the second air passage 24 to the inner side of the inner basket 25, and then enter the inner side of the middle basket 22 through the second vent 253.

[0037] An inner basket 25 is also provided inside the middle basket 22. Molecular sieves are filled between the outer side of the inner basket 25 and the inner side of the middle basket 22. After the material enters the second air passage 24, it can flow downward to the inner side of the inner basket 25 in addition to entering the inner side of the middle basket 22 through the first air hole 222, and then enter the inner side of the middle basket 22 through the second air hole 253. This allows the material to enter the molecular sieve in the middle area for adsorption, further improving the uniformity of material dispersion and increasing the utilization rate of the molecular sieve.

[0038] Furthermore, the third baffle 251 is provided with multiple third vent holes, and the fourth baffle 252 is provided with multiple fourth vent holes (not shown in the attached figure). The diameters of the third and fourth vent holes are smaller than the size of the molecular sieve, allowing the material to pass through the third and fourth vent holes and enter the inner side of the middle basket 22. This further increases the contact area between the material and the molecular sieve, improves the uniformity of material dispersion, and increases the utilization rate of the molecular sieve.

[0039] In some specific embodiments, reference is made to Figure 2 and Figure 4 The outer basket 21 is provided with a spiral plate 214 that rises spirally. The groove 32 formed by the spiral plate 214 on the outer periphery of the outer basket 21 is the first air passage 23. The feed hole 212 is connected to the lower side of the first air passage 23, and the air passage 213 is located on the upper side of the first air passage 23 and the second air passage 24.

[0040] A spiral plate 214 is set on the outer periphery of the outer basket 21 to form a first air passage 23. The material enters the first air passage 23 from the bottom and flows spirally up along the first air passage 23 to the air passage 213. Then the material flows down through the second air passage 24. This has a better buffering effect on the material and makes the subsequent dispersion more uniform.

[0041] In some specific embodiments, reference is made to Figure 2 The adsorber also includes a base 3. The lower end of the outer cylinder 1 is fixedly connected to the base 3 by a first screw 31. The lower end of the outer basket 21 is fixedly connected to the base 3. Specifically, the outer basket 21 and the base 3 are connected by welding. The upper end of the middle basket 22 is fixedly connected to the upper end of the outer basket 21 by a second screw 26.

[0042] In this way, the outer cylinder 1 can be separated from the base 3, and the middle basket 22 can be separated from the outer basket 21. After long-term use, it is convenient to disassemble and clean the gap between the outer basket 21 and the middle basket 22, the first vent 222 on the middle basket 22, and the second vent 253 on the inner basket 25.

[0043] Furthermore, the lower end face of the outer cylinder 1 is provided with a protruding ring 11, the upper side of the base 3 is provided with a groove 32, a sealing gasket 33 is provided in the groove 32, and the protruding ring 11 is inserted into the groove 32 and presses against the sealing gasket 33. Alternatively, the lower end face of the outer cylinder 1 is provided with a groove 32, the upper side of the base 3 is provided with a protruding ring 11, a sealing gasket 33 is provided in the groove 32, and the protruding ring 11 is inserted into the groove 32 and presses against the sealing gasket 33.

[0044] The lower end of the outer cylinder 1 and the upper side of the base 3 are provided with a convex ring 11 and a groove 32 for sealing. A sealing gasket 33 is provided in the groove 32 to improve the sealing performance. It can be used for adsorption of highly toxic, flammable and explosive materials with high purity requirements.

[0045] In some specific embodiments, the adsorber also includes a feed pipe 34, which is fixed on the base 3 and extends upward from the base 3 to the inner side of the outer basket 21. A feed hole 212 is provided on the outer basket 21, and the end of the feed pipe 34 is fixedly connected to the feed hole 212.

[0046] The feed pipe 34 extends from the base 3 to the inside of the outer basket 21 and connects with the outer basket 21. This way, when removing the outer cylinder 1, it is not necessary to disassemble the feed pipe 34, making disassembly and assembly more convenient.

[0047] In some specific embodiments, reference is made to Figure 5 and Figure 6 The outer cylinder 1 is provided with several heat-conducting fins 12, which are located on the upper side of the distributor 2 and extend along the radial and axial directions of the outer cylinder 1.

[0048] The heat-conducting fins 12 can transfer heat at multiple vertical and radial positions inside the outer cylinder 1, making the temperature inside the outer cylinder 1 more uniform and avoiding excessively high local temperatures and large internal temperature differences, which would affect the adsorption effect.

[0049] In some specific embodiments, the adsorber also includes an upper cover 4, which is placed on the upper side of the outer cylinder 1. The outer cylinder 1 and the upper cover 4 are detachably connected, specifically by screws. The discharge pipe 41 is provided on the upper cover 4. A limiting plate 42 is fixed on the lower side of the upper cover 4. The limiting plate 42 is located on the inner side of the outer cylinder 1. The limiting plate 42 is provided with a plurality of fifth vent holes (not shown in the figure). The diameter of the fifth vent holes is smaller than the size of the molecular sieve. The limiting plate 42 is used to limit the height of the molecular sieve on the upper side of the molecular sieve.

[0050] After adsorption, the material flows upward through the fifth vent. The limiting plate 42 on the upper side of the molecular sieve can limit the molecular sieve from exceeding the height of the outer cylinder 1, and the compacted molecular sieve ensures that the molecular sieve inside the adsorber will not be blown up and down by the airflow.

[0051] In another aspect, referring to Figure 7 and Figure 8 Furthermore, an adsorption system with at least two of the above-mentioned adsorbers is proposed. The at least two adsorbers are connected in series and connected in series by a series pipe 5. The series pipe 5 extends in a curved shape and a heat sink 51 is provided on the outside of the series pipe 5.

[0052] At least two adsorbers are connected in series, which can improve the purification effect after the material undergoes multi-stage adsorption. Setting the series pipe 5 to extend in a curved shape can extend the flow and heat dissipation distance of the material, and heat dissipation fins 51 are installed on the series pipe 5 to facilitate the heat dissipation of high-temperature materials and improve the adsorption effect of the adsorber.

[0053] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
