Description

Technical Field

Each set of adsorption tubes is filled with an adsorbent. However, the gas to be separated, such as compressed air, often contains oil, which can easily contaminate the adsorbent, reducing efficiency and shortening its lifespan.

[0071] In order to further illustrate the principle and structure of the present disclosure, preferred embodiments of the present disclosure are now described in detail with reference to the accompanying drawings.

[0072] The present disclosure provides an adsorption separation device that, depending on the function of the adsorbent material it contains, can be used to separate moisture from gas or oxygen and nitrogen from air. For example, if the adsorbent material is alumina, the adsorption separation device removes moisture from the gas; if the adsorbent material is a carbon molecular sieve, it removes oxygen from the air; and if the adsorbent material is fluorspar, it removes nitrogen from the air. The adsorption separation device disclosed herein can achieve different functions based on actual usage requirements.

[0073] First embodiment

[0074] like Figures 1 to 3 As shown, the present disclosure provides an adsorption separation device 100, which includes an upper air pipe 11, a lower air pipe 13, an adsorption tube assembly 12 located between the upper air pipe 11 and the lower air pipe 13, an oil-water separation seat 14 located at the end of the lower air pipe 13, and an oil-water separator 15 arranged in the oil-water separation seat 14. The upper end of the adsorption tube assembly 12 is connected to the upper air pipe 11, and the lower end is connected to the lower air pipe 13, and the interior thereof is communicated with the upper air pipe 11 and the lower air pipe 13. An inner cavity is formed inside the oil-water separation seat 14, and an air inlet interface 141 is provided on the outer side thereof, and the inner cavity is communicated with the air inlet interface 141 and the lower air pipe 13. The oil-water separator 15 is located in the inner cavity, combined with Figure 4 As shown, the oil-water separator 15 includes a separator shell 151 and a multi-layer wire mesh 152 filled in the separator shell 151. A plurality of through holes are opened on the separator shell 151. The air flow enters the separator shell 151 from the air inlet interface 141 and contacts the wire mesh 152 for oil-water separation, and then enters the adsorption tube assembly 12.

[0075] The present invention incorporates an oil-water separator 15 at the air inlet port 141 of the adsorption separation device 100. This allows the airflow to undergo oil-water separation before entering the adsorption tube assembly 12, preventing oil from contaminating the adsorbent within the adsorption tube assembly 12. The multiple layers of mesh within the separator housing 151 prolong the contact time between the airflow and the mesh 152, ensuring sufficient contact between the airflow and the mesh 152 and condensing the oil into liquid oil for separation, thereby fully removing the oil from the airflow. Simultaneously, some saturated water vapor in the airflow to be separated also condenses into liquid water upon encountering the mesh 152 and is then separated.

[0076] The separator housing 151 may be a square tube, and a plurality of the through holes 153 are spaced apart on the side of the square tube, so that the airflow to be separated can enter from the side of the square tube through the through holes 153 and contact the wire mesh 152 .

[0077] One or more upper air cavities 111 may be formed in the upper air tube 11. Figure 5 As shown, four upper air cavities 111 are formed inside the upper air tube 11, and each upper air cavity is isolated from the others. One or more lower air cavities can be formed inside the lower air tube 13, such as Figure 6 As shown, four lower air cavities 131 are formed inside the lower air pipe 13 , and the lower air cavities 131 are isolated from each other.

[0078] Please continue reading Figure 1 The adsorption tube assembly 12 includes a first group of adsorption tubes 12a and a second group of adsorption tubes 12b, which alternately perform adsorption and regeneration operations. Each group of adsorption tubes includes one or more rows of adsorption tubes. For example, Figure 1 In the embodiment, each group of adsorption tubes includes two rows of adsorption tubes. Each row of adsorption tubes includes multiple adsorption tubes. Figure 7 As shown, each adsorption tube includes a core-fixing tube housing 121 and an adsorption core 122 fixed therein. The adsorption core 122 is filled with adsorbent. The upper and lower end surfaces of the core-fixing tube housing 121 are provided with fixing holes. Fasteners pass through the fixing holes in the upper end surface of the core-fixing tube housing 121 to detachably connect the upper end surface of the core-fixing tube housing 121 to the upper tube 11. Fasteners pass through the fixing holes in the lower end surface of the core-fixing tube housing 121 to detachably connect the lower end surface of the core-fixing tube housing 121 to the lower tube 13.

[0079] It is understandable that Figure 7 The structure of the adsorption tube assembly shown is only an exemplary structure, and the structure of the adsorption tube assembly 12 may also be other structures that achieve similar or analogous functions.

[0080] Combine Figure 2 and Figure 3 As shown, an intake valve seat 17 is further provided at the rear end of the lower air pipe 11. This intake valve seat 17 extends from the leftmost end to the rightmost end of the lower air pipe 11, spanning each lower air cavity. One or more intake valve assemblies 16 are mounted on the intake valve seat 17. Each lower air cavity 131 is provided with a corresponding intake valve assembly 16 to control the flow direction of air into or into each lower air cavity 131.

[0081] The intake valve assembly 16 includes a valve body 162 mounted on the intake valve seat 17 and a control cylinder 161 for actuating the valve body 162. An intake valve chamber is formed within the intake valve seat 17, communicating with the inner cavity of the oil-water separator seat 14. A communication port is defined between the intake valve chamber and the corresponding lower air chamber 131. When the valve body 162 opens the communication port, the inner cavity of the oil-water separator seat 14 communicates with the corresponding lower air chamber 131.

[0082] The adsorption separation device 100 also includes an exhaust valve seat 18 disposed on the lower surface of the lower air pipe 13. This exhaust valve seat 18 is located directly below the intake valve seat. An exhaust valve cavity is formed within the exhaust valve seat 18. This exhaust valve cavity communicates with each of the lower air cavities. A valve body 162 blocks the communication between this exhaust valve cavity and each of the lower air cavities. An exhaust port 181 is provided on the side of the exhaust valve seat 18. The exhaust valve cavity communicates with this port 181 to discharge regenerated exhaust gas from the lower air cavities.

[0083] The valve body 162 includes an outer shaft 1621, an inner shaft 1623 that is retractable relative to the outer shaft 1621, an intake pressure plate 1622 disposed on the outer shaft 1621, and an exhaust pressure plate 1624 disposed on the inner shaft 1623. The control cylinder 161 controls the outer shaft 1621 to extend or retract, causing the intake pressure plate 1622 to close or open the connection between the lower air cavity of the lower air pipe and the intake valve cavity. The control cylinder 161 controls the inner shaft 1623 to extend or retract, causing the exhaust pressure plate 1624 to close or open the connection between the lower air cavity of the lower air pipe and the exhaust valve cavity. Because the first and second adsorption tube groups 12a, 12b of the adsorption tube assembly 12 alternate between adsorption and regeneration operations, the control cylinder 161 controls the intake pressure plate 1622 to close the connection between the lower air chamber of the lower air pipe and the intake valve chamber while simultaneously controlling the exhaust pressure plate 1624 to open the connection between the lower air chamber of the lower air pipe and the exhaust valve chamber. Conversely, when the control cylinder 161 controls the intake pressure plate 1622 to open the connection between the lower air chamber of the lower air pipe and the intake valve chamber, it simultaneously controls the exhaust pressure plate 1624 to close the connection between the lower air chamber of the lower air pipe and the exhaust valve chamber. This allows the lower air chamber corresponding to the adsorption working group to intake air, while the lower air chamber corresponding to the regeneration working group to exhaust air, achieving switching between intake and exhaust.

[0084] The oil-water separation seat 14 is located on the outer end face of the intake valve seat 17. The oil-water separation seat 14 has an opening facing the side of the intake valve seat 17. The outer end face of the intake valve seat 17 has an opening. The opening of the intake valve seat 17 is aligned front to back with the opening of the oil-water separation seat 14.

[0085] It should be noted that the terms "front," "rear," "left," and "right" used in this disclosure to indicate positions or locations are based on those shown in the accompanying drawings and are intended solely for ease of description and simplification. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. In this disclosure, the intake valve seat and oil-water separator seat are located at the rear end, with the opposite direction being the front end. Accordingly, the left-right direction is perpendicular to the front-to-back direction.

[0086] The oil-water separator 15 lies flat on the oil-water separator seat 14 and extends from the leftmost end to the rightmost end of the lower air pipe 13, connecting it to each lower air cavity 131. The stacking direction of the wire mesh 152 is perpendicular to the air intake direction of the air intake port 141, that is, the stacking direction of the wire mesh 152 is perpendicular to the hole axis of the air intake port 141. In this way, air enters through the through-holes in the separator housing 151 and sequentially contacts each layer of wire mesh 152, fully separating the oil and water.

[0087] An oil drain valve 183 is provided at the bottom of the lower air pipe 13, and the oil and water separated from the oil-water separator 15 are discharged through the oil drain valve 183. Each lower air cavity is correspondingly provided with an oil drain valve 183 to discharge the oil and water gathered in each lower air cavity through the oil drain valve 183.

[0088] The airflow after oil-water separation enters the lower air cavity, and from the lower air cavity enters the adsorption mold core of the adsorption tube assembly 12 for adsorption separation. The airflow after adsorption separation converges in the upper air cavity of the upper air pipe 11.

[0089] like Figure 2 As shown, the adsorption separation device also includes an outlet valve seat 192 installed at the end of the upper air pipe 11, and an outlet one-way valve 193 is provided on the outlet valve seat 192. Each upper air cavity of the upper air pipe 11 is provided with an outlet one-way valve 193 to control the direction of the airflow in the upper air cavity.

[0090] Combine Figure 1 As shown, the adsorption separation device also includes an outlet filter 19 located on the rear side of the adsorption tube assembly 12. The outlet filter 19 is used to remove impurities such as dust and particles from the airflow after separation. The filter element of the outlet filter 19 can be a PP cotton filter element, an activated carbon filter element, etc.

[0091] The air outlet filter device 19 is provided with an air outlet interface 191 , and the air outlet interface 191 can be connected to a gas user end.

[0092] The airflow after adsorption and separation enters the air outlet filter device 19 and is filtered before flowing to the air-using end through the air outlet interface 191 .

[0093] The following uses an adsorption separation device for separating moisture from compressed air as an example to illustrate the working principle of the adsorption separation device disclosed herein: the gas to be separated from moisture enters the oil-water separation seat 14 through the air inlet interface 141, and contacts the wire mesh of the oil-water separator 15 for oil-water separation. The airflow after oil-water separation enters one of the lower air cavities of the lower air pipe 13, and enters the adsorption mold core 122 (for example, the adsorption mold core of the first group) connected to the lower air cavity from the group of lower air cavities for adsorption dehydration. The dehydrated airflow enters one of the upper air cavities of the upper air pipe 11 corresponding to the lower air cavity. The airflow pressure of the upper air cavity pushes the outlet one-way valve 193 on the outlet valve seat 192 to open, connecting the air outlet interface 191, so that the dried gas flows to the gas-using end. Most of the airflow in this group of upper air cavities flows out through the air outlet port 191, while a small portion of the airflow enters another group of upper air cavities in the upper air pipe 11 through the pipe added at the top of the upper air pipe, and then enters another group of adsorption mold cores 122 (i.e., the second group of adsorption mold cores) for purging, removing moisture from the adsorbent and causing the adsorbent to desorb and regenerate. The regenerated gas enters another group of lower air cavities in the lower air pipe 13 and is discharged through the exhaust port 181. When the adsorption mold cores 122 of the first group are saturated with adsorption, a switch is performed, i.e., the adsorption mold cores 122 of the second group perform adsorption, while the adsorption mold cores 122 of the first group perform desorption and regeneration. In this way, the two groups of adsorption mold cores alternate between adsorption and regeneration.

The upper end of the adsorption tube assembly 32 is connected to the upper air pipe 31, and the lower end is connected to the lower air pipe 33. The interior of the adsorption tube assembly 32 is in communication with both the upper and lower air pipes 31, 33.

[0096] The oil-water separator 34 is located at the end of the upper refrigeration air pipe 41 and defines an inner cavity therein, which is in communication with both the air inlet port and the upper refrigeration air pipe 41.

The separator housing is provided with multiple through-holes. Airflow enters the separator housing from the air inlet port, comes into contact with the wire mesh, undergoes oil-water separation, and then enters the adsorption tube assembly.

[0097] The present invention incorporates an oil-water separator 35 at the air inlet port of the adsorption separation device 300, separating the oil and water in the airflow to be separated before entering the adsorption tube assembly 32, thus preventing oil from contaminating the adsorbent in the adsorption tube assembly 32. The separator's housing is equipped with multiple layers of wire mesh, which prolongs the contact time between the airflow and the mesh, ensuring sufficient contact between the airflow and the mesh, condensing the oil in the airflow into liquid oil and separating it, thereby fully removing the oil from the airflow. Simultaneously, some saturated water vapor in the airflow to be separated also condenses into liquid water upon encountering the mesh and is then separated.

[0098] like Figure 8 and Figure 9 As shown, the upper refrigeration pipe 41 is formed with a plurality of spaced-apart upper refrigeration cavities 411, each of which communicates with a corresponding row of evaporation tubes 42. The oil-water separator 34 is disposed on the lower surface of the upper refrigeration pipe 41. A communication port 412 is defined between the inner cavity of the oil-water separator 34 and each of the upper refrigeration cavities 411 of the upper refrigeration pipe 41, allowing each of the upper refrigeration cavities 411 to communicate with the inner cavity of the oil-water separator 34.

[0099] The oil-water separator 35 is placed flat in the inner cavity of the oil-water separator seat 34. The oil-water separator 35 almost fills the entire inner cavity of the oil-water separator seat 34, so that the airflow after oil-water separation can flow evenly to each refrigeration upper air cavity 411.

[0100] An air intake filter 492 is mounted on the lower surface of the oil-water separator 35 to remove dust, particles, and other impurities from the airflow. The filter element of this air intake filter 492 can be a PP cotton filter element, an activated carbon filter element, or the like. An air intake port 491 is provided on the outer side of the top of the air intake filter 492 for receiving the gas to be separated. The air intake filter 492 connects the air intake port 491 with the inner cavity of the oil-water separator 34. After the gas to be separated passes through the filter 492 and is filtered for impurities, it enters the oil-water separator 34 for oil-water separation. The gas then passes through the upper refrigeration air pipe 41 and enters the evaporator 42 for pre-cooling.

[0101] In this embodiment, there are two rows of evaporating tubes 42. Correspondingly, the upper refrigeration air pipe 41 has two mutually separated upper refrigeration air cavities 411, which are respectively connected to the upper ends of a row of evaporating tubes 42; the lower refrigeration air pipe 43 also has two mutually separated lower refrigeration air cavities, which are respectively connected to the lower ends of a row of evaporating tubes 42.

[0102] The adsorption separation device 300 also includes a bottom oil-water separator seat 44 having an inner cavity, which is disposed at the end of the refrigeration lower air pipe 43, and a bottom oil-water separator 45 in which the bottom oil-water separator 44 is disposed. The bottom oil-water separator seat 44 extends from the left end to the right end of the refrigeration lower air pipe 43, so that the inner cavity of the bottom oil-water separator seat 44 can communicate with each refrigeration lower air cavity of the refrigeration lower air pipe 43. The bottom oil-water separator seat 44 is located on the lower surface of the refrigeration lower air pipe 43. The structure of the bottom oil-water separator 45 is the same as that of the oil-water separator 15 in the first embodiment. It includes a bottom separator shell and a multi-layer bottom screen filled in the bottom separator shell. The bottom separator shell is provided with multiple through holes. Airflow enters the bottom separator shell from the refrigeration lower air pipe 43 and contacts the bottom screen to separate oil and water.

[0103] The bottom screen roughly fills the entire inner cavity of the bottom oil-water separator 44, so that each refrigeration upper air cavity of the refrigeration lower air pipe 43 can fully contact the bottom screen. The stacking direction of the bottom screen is perpendicular to the direction of airflow entering from the refrigeration lower air pipe 43.

[0104] Combine Figure 10 and Figure 11 As shown, a baffle 432 is provided within the lower refrigeration air cavity 431 of the lower refrigeration air pipe 43 and above the inner cavity of the bottom oil-water separator 44. The baffle 432 divides the lower refrigeration air cavity 431 into two spaces: a first space 431a and a second space 431b. The lower surface of the lower refrigeration air pipe 43 has openings corresponding to each lower refrigeration air cavity, which communicate with the bottom oil-water separator 44. The baffle 432 is provided above each opening, dividing the opening into two secondary openings 431c and 431d. The secondary openings 431c and 431d are connected to the inner cavity of the bottom oil-water separator 44. Air flows from the first space 431a through the secondary opening 431c into the inner cavity of the bottom oil-water separator 44 for oil-water separation, and then flows through the other secondary opening 431d to the second space 431.

[0105] The bottom of the bottom oil-water separator 44 is further provided with an oil drain valve 441 for draining the oil and water gathered at the bottom of the bottom oil-water separator 44. Accordingly, one oil drain valve 441 may be provided for each lower refrigeration air cavity.

[0106] The adsorption separation device 300 further includes an intake valve seat 37, which is disposed at the ends of the lower air pipe 31 and the end of the cooling lower air pipe 43. That is, the intake valve seat 37 extends from the cooling lower air pipe 43 to the lower air pipe 33. An intake valve cavity is formed within the intake valve seat 37, which connects the cooling lower air pipe 43 and the lower air pipe 33.

[0107] The intake valve seat 37 is located on the upper surface of the refrigeration lower air pipe 43. The first space 431a connects the evaporation tube 42 and the inner cavity of the bottom oil-water separation seat 44. The second space 431b connects the inner cavity of the bottom oil-water separation seat 44 and the intake valve cavity, so that the pre-cooled air flow enters the inner cavity of the bottom oil-water separation seat 44 from the first space 431a for oil-water separation, and then enters the intake valve cavity through the second space 431b, and then enters the lower air pipe 33 through the intake valve cavity.

[0108] In this embodiment, the lower air pipe 33 is formed with two lower air cavities, and correspondingly, the upper air pipe 31 is also formed with two lower air cavities, and the adsorption tube assembly 32 includes two rows.

[0109] It can be understood that the number of air cavities formed by the lower air pipe 33 and the upper air pipe 31 can be changed according to actual applications. Accordingly, the number of rows of the adsorption tube assembly 32 can also be changed according to actual applications.

[0110] In this embodiment, the internal structure and function of the adsorption tube assembly 32 are the same as those of the adsorption tube assembly 12 of the first embodiment, and are not described in detail here.

[0111] An intake valve assembly 36 is mounted on an intake valve seat 37 corresponding to the lower air cavity of each lower air pipe to control airflow to the corresponding lower air cavity. An exhaust valve seat 38 is also located on the lower surface of the lower air pipe 33, juxtaposed with the oil-water separator seat 44 at the bottom. An exhaust port is provided on the side of the exhaust valve seat 38 to discharge exhaust gas after regeneration.

[0112] In this embodiment, the internal structure and function of the intake valve assembly 36 are the same as those of the intake valve assembly 16 in the first embodiment, and are not described in detail here.

[0113] like Figure 12 As shown, a refrigerant tube or refrigerant channel 421 is provided in the evaporating tube 42, and an air flow channel 422 is formed. The air flow channel 422 is connected to the upper refrigeration air pipe 41 and the lower refrigeration air pipe 43. The air flow can exchange heat with the refrigerant in the refrigerant channel 421 or the refrigerant tube to achieve pre-cooling.

[0114] It is understandable that Figure 12 The structure of the evaporation tube shown is only an exemplary structure, and the structure of the evaporation tube may also be other structures that achieve similar or analogous functions.

[0115] like Figure 8 As shown, the pre-cooling component 40 also includes a refrigerant compressor 461 , a heat recovery unit 462 , a condensing unit 463 , a refrigerant filter 464 and a throttling device 465 .

[0116] The refrigerant compressor 461 is used to compress the high-temperature, high-pressure gaseous refrigerant output by the evaporator 42 into a high-temperature, high-pressure liquid refrigerant. The heat recovery unit 462 is used to cool the high-temperature, high-pressure liquid refrigerant output by the refrigerant compressor 461 to a medium-temperature, high-pressure liquid refrigerant, and to utilize the high-temperature, high-pressure liquid refrigerant to perform heat exchange with the separated regeneration airflow to increase the temperature of the regeneration airflow, thereby improving the regeneration capacity of the regeneration airflow for the adsorbent and improving the recycling rate. The condensing unit 463 is used to condense the medium-temperature, high-pressure liquid refrigerant output by the heat recovery unit 462 into a low-temperature, high-pressure liquid refrigerant. The refrigerant filter 464 is used to filter impurities in the low-temperature, high-pressure liquid refrigerant output by the condensing unit 463. The throttling device 465 is used to reduce the pressure of the low-temperature, high-pressure liquid refrigerant filtered by the refrigerant filter 464 to a low-temperature, low-pressure liquid refrigerant, and the reduced-pressure low-pressure liquid refrigerant is transported to the evaporator 42.

[0117] The heat recovery unit 462 includes a heat recovery outer shell and a refrigerant channel arranged in the heat recovery outer shell. The refrigerant channel is connected to the output end of the refrigerant compressor 461. The high-temperature and high-pressure refrigerant output by the refrigerant compressor 461 flows into the refrigerant channel. The regeneration airflow is introduced into the inner cavity of the heat recovery outer shell. The regeneration airflow exchanges heat with the pipe wall of the refrigerant channel. On the one hand, the refrigerant is cooled, and on the other hand, the temperature of the regeneration airflow increases, which is conducive to improving the regeneration capacity and taking away more moisture.

[0118] There are multiple heat recovery units 462, each located between the upper refrigeration air pipe 41 and the lower refrigeration air pipe 43, and not connected to the upper refrigeration air pipe 41 and the lower refrigeration air pipe 43. Heat recovery units 462 include two regeneration air flow pipes, one end of each of which connects to an upper air cavity of the upper air pipe and the other end connects to the top of the heat recovery outer shell. This allows the separated airflow in the upper air cavity to be swept from the top to the bottom of the heat recovery outer shell, exchanging heat with the high-temperature, high-pressure refrigerant in the refrigerant channel. The airflow after heat exchange is transported to the upper air cavity of the regeneration group through an external pipe. The airflow in the upper air cavity sweeps downward to desorb and regenerate the adsorbent in the regeneration group.

[0119] The heat recovery unit 462 may include a spiral refrigerant pipe extending from the top to the bottom of the heat recovery outer shell, and the inner cavity of the refrigerant pipe is a refrigerant channel.

[0120] The heat recovery unit 462 may also include a metal tube and fins arranged on the outer periphery of the metal tube, wherein the inner cavity of the metal tube is a refrigerant channel. The metal tube and the fins may be integrally formed.

[0121] The condensing unit 463 includes a condenser 4631 and a fan 4632. A refrigerant pipe for circulating refrigerant is provided in the condenser 4631, and the fan 4632 blows the refrigerant pipe to dissipate heat and reduce the temperature of the refrigerant.

[0122] The condenser 4631 may include a winding copper tube and fins welded to the copper tube. The refrigerant flows into the copper tube and is cooled by the fins and the fan.

[0123] In addition, the condenser 4631 can also use the low-temperature gas after adsorption separation to cool the refrigerant and recycle energy. Specifically, the condenser 4631 includes a condenser shell and a condenser tube disposed within the condenser shell. A portion of the cooling airflow in the upper air pipe 31 can be directed into the condenser shell through a pipeline to exchange heat with the high-temperature refrigerant in the condenser tube. The high-temperature airflow after heat exchange can be directed to the gas user through a pipeline.

[0124] The throttling device 465 can be a capillary tube.

[0125] The front side of the adsorption separation device 300 is further provided with a control component part 51, which includes a controller and control components such as a solenoid valve. A touch control panel is provided in front of the control component part 51.

[0126] In this embodiment, the airflow undergoes a first oil-water separation before entering the pre-cooling assembly 40, and then enters the bottom oil-water separator for a second oil-water separation after pre-cooling. Thus, through multiple separations, the oil is more fully separated before the airflow enters the adsorption tube assembly, thereby avoiding oil contamination of the adsorbent and also avoiding a reduction in adsorption efficiency due to contamination.

[0127] In addition, in other embodiments, the adsorption separation device of the present invention may not need to perform oil-water separation twice, that is, the number and location of the oil-water separators to be installed can be selected according to actual applications. For example, the oil-water separator 35 can be installed only on the lower surface of the upper refrigeration air pipe, or the oil-water separator 45 can be installed only on the lower surface of the lower refrigeration air pipe, that is, oil-water separation is performed before the airflow enters the pre-cooling component 40, or oil-water separation is performed after the airflow is pre-cooled.

[0128] In another embodiment, the present disclosure provides an adsorption separation device. In this embodiment, the oil-water separator is installed after the air flow is pre-cooled and before the adsorption separation is performed. Specifically, the adsorption separation device includes an upper air pipe, a lower air pipe, an adsorption tube assembly, a pre-cooling assembly, an oil-water separation seat and an oil-water separator.

A refrigerant pipe or a refrigerant channel is arranged in the evaporation tube, and an airflow channel is formed. The airflow channels are connected to the refrigeration upper air pipe and the refrigeration lower air pipe. The airflow can exchange heat with the refrigerant in the refrigerant channel or the refrigerant pipe to achieve pre-cooling.

[0130] The oil-water separation seat is arranged at the end of the refrigeration lower air pipe, and an inner cavity is formed inside the seat. The inner cavity is communicated with the refrigeration lower air pipe, and the inner cavity can also be communicated with the lower air pipe.

[0131] The oil-water separator is located in the inner cavity, which includes a separator shell and a multi-layer wire mesh filled in the separator shell. The separator shell is provided with multiple through holes. The air flow enters the separator shell from the refrigeration downpipe, contacts the wire mesh for oil and water separation, and then enters the downpipe.

[0132] In this embodiment, the oil-water separator has the same structure and function as the oil-water separator 44 of the second embodiment; the oil-water separator has the same structure and function as the oil-water separator 45 of the second embodiment; and they will not be described in detail here.

[0133] A baffle is provided inside the refrigeration lower air cavity of the refrigeration lower air pipe and above the inner cavity of the oil-water separation seat. The baffle divides the refrigeration lower air cavity into two spaces, namely the first space and the second space. The air flow enters the inner cavity of the oil-water separation seat from the first space for oil and water separation and then flows to the second space.

[0134] The adsorption separation device also includes an intake valve seat, which is arranged at the end of the downpipe and the end of the refrigeration downpipe. An intake valve cavity is formed inside the intake valve seat, and the intake valve cavity can connect the refrigeration downpipe and the downpipe. The oil-water separator seat is located on the lower surface of the refrigeration downpipe, and the intake valve seat is located on the upper surface of the refrigeration downpipe. The first space connects the evaporation tube and the inner cavity of the oil-water separator seat, and the second space connects the inner cavity of the oil-water separator seat and the intake valve cavity, so that the pre-cooled airflow enters the inner cavity of the oil-water separator seat from the first space for oil-water separation, then passes through the second space into the intake valve cavity, then passes through the intake valve cavity into the downpipe, and finally enters the adsorption tube assembly for adsorption separation.

[0135] The above are only preferred feasible embodiments of the present disclosure and are not intended to limit the protection scope of the present disclosure.
