Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a rotary device and a rotary adsorption and recovery system. Background Technology

[0002] Currently, fixed-bed adsorption recovery technology is widely used in waste gas adsorption and recovery treatment. However, it has disadvantages such as long desorption time and high energy consumption, and the utilization rate of fixed beds is low when the waste gas concentration is low. To solve this problem, rotary adsorption recovery technology has emerged.

[0003] The rotary adsorption impeller has internal channels for gas flow. Gas flow structures are located on opposite sides of the impeller, one serving as an inlet and the other as an outlet. The internal cavity of each gas flow structure is divided into multiple chambers. Poor sealing between the gas flow structure and the impeller leads to gas leakage between adjacent chambers, thus reducing the effectiveness of waste gas treatment.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] In response to the problems pointed out in the background art, this utility model proposes a rotary device and a rotary adsorption and recovery system to improve the sealing effect between the gas flow structure and the rotary wheel, thereby improving the waste gas treatment effect.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0007] In some embodiments of this application, a rotating device is provided, including a rotating wheel and a gas flow structure; the rotating wheel is provided with multiple channel units for gas flow; the gas flow structure is disposed on the end side of the rotating wheel, including a sealing body and a sealing end face; multiple chambers for gas flow are formed inside the sealing body, and the chambers communicate with the channel units; the sealing end face is disposed on the side of the sealing body facing the rotating wheel and surrounds the air outlet of the chamber, and the sealing end face is configured to abut against the end face of the rotating wheel to form a surface seal. In some embodiments of this application, the sealing body has a fan-shaped structure, the fan-shaped structure in which the sealing body is located is coaxial with the rotating wheel, and the multiple chambers are arranged sequentially along the circumference of the sealing body.

[0008] In some embodiments of this application, the sealing end face includes a first sealing end face located between the air outlets of two adjacent chambers. The first sealing end face is configured to abut against the end face of the rotating wheel to form a surface seal, thereby preventing gas from flowing between the air outlets of two adjacent chambers.

[0009] In some embodiments of this application, the sealing end face includes a second sealing end face located radially outward of the outer chamber. The second sealing end face is configured to abut against the end face of the rotating wheel to form a surface seal, thereby preventing gas from flowing between the vent of the chamber and the outer space.

[0010] In some embodiments of this application, the sealing end face includes two arc-shaped sealing end faces, one of which is disposed on the outer peripheral side of the sealing body, and the other arc-shaped sealing end face is disposed on the inner peripheral side of the sealing body. The arc-shaped sealing end face is configured to abut against the end face of the rotating wheel to form a surface seal.

[0011] In some embodiments of this application, the gas flow structure further includes a sealing gasket, which covers the sealing end face facing the rotor and is configured to seal against the end face of the rotor.

[0012] In some embodiments of this application, the gas flow structure further includes a buffer pad, which is disposed between the sealing end face and the sealing pad.

[0013] In some embodiments of this application, a thrust device is further included, which is configured to apply a force to the gas flow structure to seal the sealing end face against the end face of the impeller.

[0014] In some embodiments of this application, a guiding device is also included, which includes a fixed guiding part and a movable guiding part. The movable guiding part is disposed on the sealing body, and the fixed guiding part is slidably connected to the movable guiding part. The movement direction of the movable guiding part is parallel to the axial direction of the wheel.

[0015] In some embodiments of this application, a rotary adsorption recovery system is provided, including the rotary wheel device as described above.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are:

[0017] In the gas flow structure of this application, a sealing end face is arranged around the air outlet of the chamber facing the rotor. The sealing end face abuts against the end face of the rotor to seal. By increasing the area of ​​the sealing end face, a surface seal is formed between the sealing end face and the rotor, upgrading the traditional line-to-surface seal to a surface-to-surface seal. This ensures that each chamber is independent during the rotation of the rotor, preventing gas penetration between chambers. This improves the end face sealing effect between the gas flow structure and the rotor, achieving individual isolation of different chambers and preventing gas leakage between adjacent chambers and adjacent channel units inside the rotor. This ensures the gas treatment effect of each area and improves the waste gas treatment effect.

[0018] Other features and advantages of this utility model will become clearer after reading the specific embodiments of this utility model in conjunction with the accompanying drawings. Attached Figure Description

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0055] In some embodiments of this application, a sealing device is provided that has a sliding sealing function on the end face of the impeller 9 and can operate continuously in a medium-low pressure environment of 30 kPa.

[0056] See Figure 1 This application discloses an end-face sliding sealing device 10 suitable for continuous adsorption-desorption switching. During normal operation of the system, an end-face sliding sealing device 10 is arranged on each side of the rotor 9, and they are symmetrical to each other.

[0057] With the assistance of the thrust device, the sliding sealing device moves from both sides to the middle. That is, the end face sliding sealing devices 10 on both sides of the rotating wheel 9 move simultaneously to the end face sliding sealing device 10 located between the two and squeeze the sealing end face of the rotating wheel 9. At this time, the rotating wheel 9 begins to rotate slowly.

[0058] During the rotation of the rotor 9, the sealing plate is in close contact with the rotor 9 to separate the exhaust gas and allow it to enter the three independent chambers of the end face sliding sealing device 10 located in the purging zone, desorption zone, and cooling zone, thereby achieving different functions such as adsorption, desorption, cooling, and purging.

[0059] See Figure 2 and Figure 3 In this embodiment, the end-face sliding sealing device 10 suitable for continuous adsorption-desorption switching includes a sector-shaped sealing body 1. The sector-shaped sealing body 1 includes three chambers arranged sequentially at intervals along the circumference of the sector-shaped sealing body 1. The inner wall of the chamber includes a bottom surface 2 and a vertical wall, both of which are provided with a heat insulation layer 3. Each of the three chambers opens on the side facing the rotor 9 to form a chamber inlet, and a chamber outlet is opened on the other side of the chamber inlet to connect to the chamber. Each chamber outlet is connected to a pipe for conveying gas.

[0060] The aforementioned circumferential direction refers to the circumferential direction of the circle in which the sector formed by the sector-shaped sealing body 1 lies. Of course, in some embodiments, the number of chambers does not necessarily have to be three; there can be two, four, or more, depending on the actual needs.

[0061] The three chambers are arranged in sequence at intervals. Specifically, there is a sealed dead zone between two adjacent chambers. The sealed dead zone is generally a solid or hollow structure sandwiched between two adjacent chambers.

[0062] When the sealing dead zone is a hollow structure, the sector-shaped sealing body 1 is actually a large chamber. This large chamber is divided into five independent chambers by four partitions. Three of these chambers are open chambers, and two of them are sealed chambers. The sealed chambers are the sealing dead zone in this embodiment.

[0063] It should be noted that, Figure 3In the simplified diagram shown, the insulation zone refers to the sealed dead zone, and the front end of the insulation zone near the rotor is the sealing end face used to abut against the rotor. The exhaust gas treatment area refers to the chamber.

[0064] The sealing dead zone includes a first sealing end face 8, which is located between the chamber inlets of two adjacent chambers. In other words, the first sealing end face 8 faces the sealing end face of the rotating wheel 9. The first sealing end face 8 faces and can be pressed against the sealing end face of the rotating wheel 9 to form a surface seal between the chamber inlets of two adjacent chambers.

[0065] It should be noted that the width of the first sealing end face 8 cannot be less than a preset value, which can be set according to actual needs. This is mainly because after the first sealing end face 8 faces and can be pressed against the sealing end face of the rotating wheel 9, a surface-to-surface seal is formed between the two. If air leaks from one chamber into the adjacent chamber, it needs to penetrate at least the aforementioned preset value. In other words, the larger this preset value is, the lower the possibility of leakage. However, if this distance is too large, it will occupy too much space in the chamber and compress the volume of the chamber. Therefore, this preset value needs to be comprehensively considered to ensure both the sealing strength and the required chamber size.

[0066] Furthermore, the sector-shaped sealing body 1 also includes a second sealing end face 53, a first arc-shaped sealing end face 51, and a second arc-shaped sealing end face 52 surrounding the outer periphery of the sector-shaped sealing body 1. Specifically, a sealing substrate 5 is welded or integrally formed on the outer periphery of the sector-shaped sealing body 1, and one side surface of the sealing substrate 5 is located at the same horizontal plane as the first sealing end face 8.

[0067] In detail, the sealing substrate 5 mainly comprises four parts: two radial sealing substrates located at the two radial edges of the sector-shaped sealing body 1; an inner arc-shaped substrate located near the center of the sector-shaped sealing body 1; and an outer arc-shaped substrate located near the center of the sector-shaped sealing body 1 (outer arc). The radial sealing substrate, inner arc-shaped substrate, and outer arc-shaped substrate are arranged sequentially around the outer periphery of the sector-shaped sealing body 1 and each has a certain width. The purpose is to increase the sealing area of ​​the surface-to-surface contact seal and improve the sealing effect.

[0068] More specifically, the radial sealing substrate includes a second sealing end face 53 facing the sealing end face of the rotating wheel 9, the inner arc-shaped substrate includes a first arc-shaped sealing end face 51 facing the sealing end face of the rotating wheel 9, and the outer arc-shaped substrate includes a second arc-shaped sealing end face 52 facing the sealing end face of the rotating wheel 9. This forms a structure where a first sealing end face 8 and a second sealing end face 53, a first arc-shaped sealing end face 51 near its center, and a second arc-shaped sealing end face 52 away from its center are respectively provided on both sides of the width of the outermost chamber. The first sealing end face 8, the second sealing end face 53, the first arc-shaped sealing end face 51, and the second arc-shaped sealing end face 52 are all located on the same horizontal plane and can all press against and abut against the sealing end face of the rotating wheel 9 to form a surface-to-surface seal.

[0069] Furthermore, in order to improve the sealing effect of the face-to-face sealing structure, the end face sliding sealing device 10 also includes a buffer pad 7 and a sealing pad 6 made of polymer composite material.

[0070] The buffer pad 7 covers one side surface of the sealing substrate 5 (including the second sealing end face 53, the first arc-shaped sealing end face 51 and the second arc-shaped sealing end face 52) and the first sealing end face 8. The sealing pad 6 covers the buffer pad 7.

[0071] Of course, in some embodiments, the buffer pad 7 may not be provided, and the sealing pad 6 may be directly wrapped around one side surface of the sealing substrate 5 (including the second sealing end face 53, the first arc-shaped sealing end face 51 and the second arc-shaped sealing end face 52) and the first sealing end face 8. The sealing pad 6 is pressed against the sealing end face of the rotating wheel 9.

[0072] Furthermore, the outer edge of the sealing substrate 5 and the inner edge of the cavity inlet are provided with mounting grooves. The end face sliding sealing device 10 also includes a sealing strip 4, which has several through holes. Specifically, the outer edge of the fan-shaped sealing body 1 and the circumferential direction of the cavity inlet are provided with mounting grooves, and several threaded countersunk holes are provided in the mounting grooves. The edge of the sealing gasket 6 is embedded in the mounting groove, and the sealing strip 4 is positioned opposite to the mounting groove and pressed against the sealing gasket 6. The through holes and the threaded countersunk holes correspond one-to-one, so that the sealing strip 4 can be fixed on the mounting groove by a screw.

[0073] Furthermore, the thrust device is located on the side of the sector-shaped seal 1 facing away from the chamber inlet, which can press the sector-shaped seal 1 toward the sealing end face of the rotating wheel 9. In this embodiment, the free end of the thrust device is connected to the side of the sealing base plate 5 facing away from the chamber inlet.

[0074] In simple terms, the end-face sliding sealing device 10 of this embodiment, suitable for continuous adsorption-desorption switching, includes a sector-shaped sealing body 1, a sealing dead zone, a thrust device, and a sealing element. The sealing element is a sealing gasket 6 made of polymer composite material, which covers the end face of the dead zone and separates the sectors of different processing units of the end-face sliding sealing device 10. The sector-shaped sealing body 1 has a sealing groove, and the sealing gasket 6 is disposed in the sealing groove to isolate gas. The sealing base plate 5 has a mounting groove and a countersunk hole. The sealing gasket 6 is a sealing element made of polymer composite material, which covers the end face of the sealing dead zone and separates the sectors of different processing units. The sealing base plate 5 has a sealing groove on its edge, and the sealing gasket 6 is disposed in the sealing groove to isolate gas. It not only has an extremely low coefficient of friction and high wear resistance, but also directly contacts the end face of the rotating wheel 9 for sliding sealing, separating and collecting the gas in different stages and flowing into the cavity to the next process.

[0075] The thrust device is located on the back of the sector sealing substrate 5, and is equipped with a guide rail and a manual thread or cylinder to provide power to ensure the pressure value required for end face sealing.

[0076] A buffer pad 7 is provided between the sealing substrate and the sealing gasket 6, which can ensure the tight fit between the sealing surface and the end face during the sliding process, greatly improving the reliability of the seal.

[0077] The technical solution of this invention not only meets the sliding sealing requirements of the rotor 9 at this level, effectively solving the sealing problems of internal air leakage and high pressure in the rotor 9, but also achieves thermal insulation and isolation between different sector chambers, reducing the temperature influence between different chambers and achieving certain energy-saving benefits. The overall equipment is more compact, and through the continuous suction-desorption integrated circulation desorption process, the space area required for desorption is reduced, achieving a multi-fold reduction in public utility energy consumption. This greatly reduces the difficulty of enterprise promotion and the waste of resources.

[0078] In some embodiments of this application, an organic waste gas adsorption and desorption treatment device is provided, including a rotor 9 and end face sliding sealing devices 10 symmetrically arranged on opposite sides of the rotor 9.

[0079] In summary, the end-face sliding sealing device 10 for continuous adsorption-desorption switching provided in this application, during normal operation, allows a large amount of waste gas to enter the rotor 9. Due to the substrate and structure of the rotor 9, the interior of the rotor 9 is divided into many small channels. When the waste gas pressure rises to a certain level, the gas in the channels will pass through the substrate wall and flow into the other channels. Similarly, the waste gas and oxygen in the adsorption chamber will also flow to the desorption area simultaneously, resulting in an increase in the oxygen content inside the desorption area. At this time, the temperature and concentration of the waste gas inside the desorption area are also high, which may reach the lower explosive limit and combine with oxygen, thus posing a safety risk.

[0080] This device adds large-area sector sealing surfaces in different chambers, upgrading the traditional line-surface sealing to surface-surface sealing. Through improvements and treatments inside the rotor 9, the resistance of the substrate wall is increased, thereby controlling the range of exhaust gas dispersion. The panel design combines performance to correspond this dispersion range with the area of ​​the sealing substrate 5, ensuring that each sector is independent during rotation and that no external cavity penetrates it. This achieves individual isolation of different exhaust gas treatment areas, ensuring both oxygen concentration in high-concentration areas and exhaust gas concentration in emission areas, thus achieving safe and stable operation and compliance with emission standards for the entire device.

[0081] In some embodiments of this application, see [link to relevant documentation]. Figure 1 A honeycomb rotor is provided, comprising a rotor body and an air inlet structure and an air outlet structure disposed on opposite sides of the rotor body. The air inlet structure and the air outlet structure are the end face sliding sealing device 10 described above. The air inlet structure and the air outlet structure have the same structure.

[0082] The rotor body is made of fibrous material. The waste gas to be treated enters the rotor body through the inlet structure and is adsorbed. The treated waste gas then enters the outlet structure through the rotor body and is discharged.

[0083] Combination Figure 1 and Figure 4 From the axial perspective of the rotor body, the rotor body is divided into multiple fan-shaped independent units 01 in the circumferential direction. A separating surface 05 formed by a separating material is provided between two adjacent independent units 01. The gas permeability of the separating material is less than 350 L / m. 2 / min / 1kPa.

[0084] The separating surface 05 includes one or a combination of the following: a separating plate located between two adjacent independent units 01; or a separating membrane located between two adjacent independent units 01; or an amorphous adhesive layer located between two adjacent independent units 01. The separating surface can prevent fluid (gas) diffusion between the independent units 01.

[0085] The air intake structure includes a fan-shaped air intake cavity 021 and a first fan-shaped isolation zone 031. Multiple fan-shaped air intake cavities 021 are provided, and a first fan-shaped isolation zone 031 is provided between two adjacent fan-shaped air intake cavities 021.

[0086] The air outlet structure includes a fan-shaped air outlet cavity 022 and a second fan-shaped isolation zone 032. Multiple fan-shaped air outlet cavities 022 are provided, and a second fan-shaped isolation zone 032 is provided between two adjacent fan-shaped air outlet cavities 022.

[0087] Multiple fan-shaped air intake chambers 021 and multiple fan-shaped air outlet chambers 022 are arranged one-to-one and mirror-symmetrically on both sides of the thickness of the rotor body. The first fan-shaped isolation area 031 and the second fan-shaped isolation area 032 are arranged one-to-one and mirror-symmetrically on both sides of the thickness of the rotor body.

[0088] It should be noted that the fan-shaped air inlet chamber 021 and the fan-shaped air outlet chamber 022 are equivalent to the chambers mentioned above, and the first fan-shaped isolation area 031 and the second fan-shaped isolation area 032 are equivalent to the first sealing end face 8 and the second sealing end face 53 mentioned above.

[0089] The angle of any sector-shaped isolation zone and the angle of any sector-shaped air intake chamber 021 are both greater than or equal to the angle of any independent unit 01. It can be seen that a first sector-shaped isolation zone 031 is provided between two adjacent sector-shaped air intake chambers 021, and the angle of any first sector-shaped isolation zone 031 is greater than or equal to the angle of any independent unit 01.

[0090] When the rotor is working, no single unit 01 can simultaneously connect any two adjacent fan-shaped air inlets 021 and two fan-shaped air outlets 022, thus ensuring that no fluid diffusion occurs between two adjacent fan-shaped air inlets 021, and ensuring that the concentration and pressure of the fluid in adjacent areas on the honeycomb rotor will not change significantly when there is a concentration and pressure difference.

[0091] Combination Figure 1 In this embodiment, in order to reduce the processing difficulty, from the axial perspective of the wheel body, the angles of the fan-shaped areas where multiple independent units 01 are located are equal. That is, the wheel body is divided into multiple independent units 01 of the same size and shape in the circumferential direction, for example, 12.

[0092] Of course, in some embodiments, multiple independent units 01 can also be set to different angles, as long as the angle of any sector isolation zone and the angle of any sector air intake chamber 021 are greater than or equal to the angle of any independent unit 01.

[0093] From the axial perspective of the rotor body, the air intake and exhaust structures are fan-shaped. In the circumferential direction of the fan-shaped structure, the fan-shaped air intake chamber 021 and the first fan-shaped isolation zone 031 are alternately arranged, and the fan-shaped air exhaust chamber 022 and the second fan-shaped isolation zone 032 are alternately arranged.

[0094] Combination Figure 4In this embodiment, the fan-shaped air inlet chamber 021, the fan-shaped air outlet chamber 022, the independent unit 01, the first fan-shaped isolation area 031, and the second fan-shaped isolation area 032 are all located in the same fan-shaped area with the same angle and size. As shown in the figure, when the fan-shaped air inlet chamber 021 is directly opposite the independent unit 01, the fan-shaped air outlet chamber 022, the first fan-shaped isolation area 031, and the second fan-shaped isolation area 032 are also directly opposite the independent unit 01; at this time, the fluid path 04 is as follows... Figure 4 As shown, the airflow enters an independent unit 01 from the fan-shaped air intake chamber 021 and then enters the opposite fan-shaped air outlet chamber 022. There is an independent unit 01 between the independent units 01 corresponding to the two adjacent fan-shaped air intake chambers 021. After the airflow from the two adjacent fan-shaped air intake chambers 021 enters the corresponding independent unit 01, there are two separating surfaces 05 and an independent unit 01 between the two independent units, which completely prevents the airflow from the two adjacent fan-shaped air intake chambers 021 from entering the independent unit 01 and causing air leakage.

[0095] Combination Figure 5 In this embodiment, the fan-shaped air inlet chamber 021, the fan-shaped air outlet chamber 022, the independent unit 01, the first fan-shaped isolation area 031, and the second fan-shaped isolation area 032 are all located in the same fan-shaped area with the same angle and size. As shown in the figure, when the fan-shaped air inlet chamber 021 faces two adjacent independent units 01, since the angle of the first fan-shaped isolation area 031 is equal to the angle of the independent unit 01, the first fan-shaped isolation area 031 must face two adjacent independent units 01. That is, the first fan-shaped isolation area 031 must correspond to a separating surface 05. After the gas from the two adjacent fan-shaped air inlets 021 enters the rotor body, due to the presence of the separating surface 05 corresponding to the first fan-shaped isolation area 031, the fluid path 04 is as follows... Figure 5 As shown, the gas from two adjacent fan-shaped air intake chambers 021 cannot flow into the same independent unit 01 after entering the rotor body, so there is no gas leakage phenomenon.

[0096] Furthermore, in this embodiment, the angle of the sector where the independent unit 01 is located is 3° to 30°. The angle of the sector where the first sector isolation area 031 and the second sector isolation area 032 are located is 3° to 30°. The angle of the sector inlet chamber 021 and the sector outlet chamber 022 is 3° to 30°. Of course, in some embodiments, in order to improve fluid throughput, the angle of any sector inlet chamber 021 is greater than or equal to the angle of any independent unit 01.

[0097] Combination Figure 6In some embodiments, multiple independent units 01 have equal angles, and the angles of independent unit 01, the first sector-shaped isolation zone 031, and the second sector-shaped isolation zone 032 are equal. The angles of the sector-shaped air inlet chamber 021 and the sector-shaped air outlet chamber 022 are equal and smaller than the angle of the independent unit 01. Since the angle of the first sector-shaped isolation zone 031 is equal to the angle of the independent unit 01, the first sector-shaped isolation zone 031 must be directly opposite two adjacent independent units 01. That is, the first sector-shaped isolation zone 031 must correspond to a partition surface 05. After the gas from two adjacent sector-shaped air inlets 021 enters the rotor body, due to the presence of the partition surface 05 corresponding to the first sector-shaped isolation zone 031, the fluid path 04 is as follows... Figure 6 As shown, the gas from two adjacent fan-shaped air intake chambers 021 cannot flow into the same independent unit 01 after entering the rotor body, so there is no gas leakage phenomenon.

[0098] Combination Figure 7 When the angle of the first sector isolation region 031 is less than the angle of the independent unit 01, the first sector isolation region 031 will be located between the two separating surfaces 05 of an independent unit 01 in a certain state, such as... Figure 7 As shown, at this time, the air intake from the fan-shaped air intake chambers 021 on both sides of the first fan-shaped isolation zone 031 will converge into the same independent unit 01, resulting in air leakage. Therefore, in order to prevent air leakage, the angle between the first fan-shaped isolation zone 031 and the second fan-shaped isolation zone 032 must be greater than or equal to the angle of the independent unit 01.

[0099] In some embodiments of this application, a method for processing a rotary wheel is provided, comprising:

[0100] 1. Taking the rotation direction of the honeycomb wheel as the plane, and the center of the honeycomb wheel in the plane as the origin, several straight lines with the same angle are radiated out in the plane. The angle is 3-30°. If the angle is too large, the utilization rate of the honeycomb material is low; if the angle is too small, the processing efficiency of the honeycomb wheel is low.

[0101] 2. A straight line forms a dividing surface in the direction perpendicular to the plane. The honeycomb rotor is divided into several identical and independent units 01 along the dividing surface. An isolation zone is set between the functional areas of the rotor used to transmit fluids of different concentrations and pressures. There is no fluid transmission in the honeycomb rotor within the isolation zone. The angle of the isolation zone is not less than the interval angle of the dividing surface. The angle of the isolation zone is 3-30°. When the angle of the isolation zone is less than the interval angle of the dividing surface, diffusion between independent units 01 cannot be isolated.

[0102] 3. The aforementioned independent units are separated by a separator material to prevent diffusion between units. The separator material can be a profile such as a plate, sheet, or film, or an amorphous adhesive, or one or more of these. The gas permeability of the separator material is less than 350 L / m. 2When the gas permeability is high (e.g., / min / 1kPa), the insulation requirement cannot be met.

[0103] In some embodiments of this application, the end face sliding sealing device 10, the air inlet structure, and the air outlet structure described above are essentially the same structure, namely, the gas flow structure 200. Figure 8 This is a structural diagram of the rotor 9 and the gas flow structure 200. Figure 9 This is a structural diagram of a gas flow structure 200.

[0104] As mentioned above, refer to Figure 1 The rotating wheel 9 is provided with multiple channel units 91 for gas flow, which are the independent units 01 mentioned above. The multiple channel units 91 are distributed around the axis of the rotating wheel 9. From the axial view of the rotating wheel 9, the channel units 91 extend radially along the rotating wheel 9 and are fan-shaped.

[0105] Gas flow structures 200 are respectively provided on two opposite ends of the rotor 9, one of which serves as an air inlet and the other as an air outlet. Multiple chambers 210 for gas flow are provided within each gas flow structure 200, and these chambers 210 are connected to the channel unit 91. The two gas flow structures 200 are arranged in a one-to-one correspondence and mirror image symmetrical arrangement on opposite sides of the rotor 9, and the multiple chambers 210 within each gas flow structure 200 are also one-to-one correspondences and connected through the channel unit 91. Each chamber 210 includes two air outlets 211, one serving as a chamber outlet 213 and the other as a chamber inlet 212. The fan-shaped air inlet chamber 021 and fan-shaped air outlet chamber 022 mentioned above are chambers 210.

[0106] Specifically, refer to Figure 9 The gas flow structure 200 includes a sealing body 240. The sealing body 240 is a hollow frame structure. Multiple chambers 210 for gas flow are formed inside the sealing body 240. Thermal insulation material is provided on the inner wall of the chambers 210 to facilitate heat preservation and prevent heat exchange between adjacent chambers 210.

[0107] For example, the interior of the sealed body 240 is divided into multiple isolated chambers 210 by partitions 220. Alternatively, two adjacent chambers 210 are isolated by a hollow sealed cavity, which, while isolating the chambers 210, also helps prevent heat exchange between adjacent chambers 210.

[0108] The gas flow structure 200 also includes a sealing end face. The sealing end face is located on the side of the sealing body 240 facing the rotor 9 and surrounds the air outlet 211 of the chamber 210. The sealing end face is configured to abut against the end face of the rotor 9 to form a surface seal. For example, refer to… Figure 9In the gas flow structure 200 serving as an intake, the chamber outlet 213 faces the rotor 9, and a sealing end face surrounds the chamber outlet 213. Alternatively, in the gas flow structure 200 serving as an exhaust, the chamber inlet 212 faces the rotor 9, and a sealing end face surrounds the chamber inlet 212.

[0109] In the gas flow structure 200 of this application, a sealing end face is provided around the circumference of the air outlet 211 of the chamber facing the rotating wheel 9. The sealing end face abuts against the end face of the rotating wheel 9 to seal. By increasing the area of ​​the sealing end face, a surface seal is formed between the sealing end face and the rotating wheel 9, upgrading the traditional line-to-surface seal to a surface-to-surface seal. This ensures that each chamber 210 is independent during the rotation of the rotating wheel 9, and gas penetration between chambers 210 will not occur, thereby achieving individual isolation of different chambers 210.

[0110] In some embodiments of this application, reference is made to Figure 9 Corresponding to the fan-shaped structure of the channel unit 91, the chamber 210 also has a fan-shaped structure. The air outlet 211 of the chamber 210 is fan-shaped to communicate with the fan-shaped channel unit 91. The chamber 210 includes two opposing radial edges and two opposing circumferential arc edges.

[0111] The sealing end face includes a radial sealing end face 230, and a radial sealing end face 230 is respectively provided on the two opposite radial edges of the air outlet 211 of any chamber 210. The radial sealing end face 230 extends a certain area in the radial and circumferential directions along the rotor 9.

[0112] Along the axial direction of the rotating wheel 9, the projection of the radial sealing end face 230 overlaps the projection of any channel unit 91. The rotating wheel 9 rotates to... Figure 4 or Figure 5 or Figure 6 When the position is such that the projection of the radial sealing end face 230 can cover the projection of any channel unit 91, the wheel 9 in any working position will not be able to connect any two adjacent chambers 210 at the same time, thus ensuring that no gas diffusion can occur between the two adjacent chambers 210.

[0113] In some embodiments of this application, reference is made to Figure 8 and Figure 9 The sealing body 240 has a fan-shaped structure, and the fan-shaped structure in which the sealing body 240 is located is coaxial with the rotating wheel 9. The chamber 210 and the radial sealing end face 230 have fan-shaped structures, and multiple chambers 210 are arranged sequentially along the circumference of the sealing body 240. The rotating wheel 9 device includes a base frame 530, and the rotating wheel 9 is rotatably mounted on the base frame 530. The gas flow structure 200 is also mounted on the base frame 530.

[0114] The sector angle of the radial sealing end face 230 is not less than the sector angle of any channel unit 91. Thus, the rotating wheel 9 rotates to... Figure 4 or Figure 5 or Figure 6 When the position is such that the sector angle of the radial sealing end face 230 is not less than the sector angle of any channel unit 91, the rotor 9 in any working position cannot simultaneously connect two adjacent chambers 210 or chamber 210 with the external space, thereby ensuring that gas diffusion between two adjacent chambers 210 is avoided.

[0115] In some embodiments of this application, reference is made to Figure 9 The radial sealing end face 230 includes a first sealing end face 8, which is fan-shaped and located between the air outlets 211 of two adjacent chambers 210. The first sealing end face 8 extends from the inner circumferential arc-shaped edge of the chamber 210 to the outer circumferential arc-shaped edge. The first sealing end face 8 is configured to abut against the end face of the rotor 9 to form a surface seal, thereby preventing gas from flowing between the air outlets 211 of two adjacent chambers 210.

[0116] In other words, the first sealing end face 8 is positioned between the air vents 211 of two adjacent chambers 210, and the sector angle of the first sealing end face 8 is not less than the sector angle of any channel unit 91. Thus, the rotating wheel 9 rotates to... Figure 4 or Figure 5 or Figure 6 When the first sealing end face 8 is in a certain position, because the sector angle is not less than the sector angle of any channel unit 91, the rotor 9 is in a certain working position and no channel unit 91 can connect two adjacent chambers 210 at the same time, thereby ensuring that no gas diffusion can occur between two adjacent chambers 210.

[0117] In some embodiments of this application, reference is made to Figure 9 The radial sealing end face 230 also includes a second sealing end face 53, which is fan-shaped and located radially outward of the outer chamber 210. The second sealing end face 53 extends from the inner circumferential arcuate edge of the chamber 210 to the outer circumferential arcuate edge. The second sealing end face 53 is configured to abut against the end face of the rotor 9 to form a surface seal, thereby preventing gas from flowing between the vent 211 of the chamber 210 and the outer space.

[0118] In other words, second sealing end faces 53 are provided on the outer radial edges of the two outermost chambers 210, and the sector angle of the second sealing end faces 53 is not less than the sector angle of any channel unit 91. Thus, the rotating wheel 9 rotates to... Figure 4 or Figure 5 or Figure 6When the position is such that the sector angle of the second sealing end face 53 is not less than the sector angle of any channel unit 91, the rotor 9 in any working position cannot simultaneously connect the chamber 210 and the external space adjacent to the chamber 210, thereby preventing gas from flowing between the air outlet 211 of the chamber 210 and the external space.

[0119] It should be noted here that the first sector-shaped isolation area 031 and the second sector-shaped isolation area 032 mentioned above are the radial sealing end face 230, that is, the first sealing end face 8 and the second sealing end face 53.

[0120] In some embodiments of this application, reference is made to Figure 9 The sealing end face includes two arc-shaped sealing end faces, one of which is disposed on the outer peripheral side of the sealing body 240 (denoted as the second arc-shaped sealing end face 52), and the other arc-shaped sealing end face is disposed on the inner peripheral side of the sealing body 240 (denoted as the first arc-shaped sealing end face 51). The arc-shaped sealing end faces are configured to abut against the end face of the rotating wheel 9 to form a surface seal.

[0121] The outermost chamber 210 has a first radial sealing end face 230, a first arc-shaped sealing end face 51, a second radial sealing end face 230 and a second arc-shaped sealing end face 52 arranged sequentially around the outer periphery of the air outlet 211 near the rotor 9.

[0122] The middle chamber 210 has a first radial sealing end face 230, a first arc-shaped sealing end face 51, a first radial sealing end face 230 and a second arc-shaped sealing end face 52 arranged sequentially around the outer periphery of the air outlet 211 near the rotor 9.

[0123] Thus, the outer periphery of the air outlet 211, which connects the chamber 210 and the channel unit 91 of the rotor 9, forms a surface-to-surface sealing structure, which improves the sealing effect between the gas flow structure 200 and the end side of the rotor 9, and prevents air leakage between two adjacent chambers 210, and also prevents air leakage between two adjacent channel units 91.

[0124] In some embodiments of this application, the sector angle of any chamber 210 is not less than the sector angle of any channel unit 91. In this way, while ensuring that gas leakage between two adjacent chambers 210 is avoided, it helps to increase the gas flow rate.

[0125] In some embodiments of this application, reference is made to Figure 2 The gas flow structure 200 also includes a sealing gasket 6, which covers the sealing end face facing the rotor 9 and is configured to seal against the end face of the rotor 9. For example, the sealing gasket 6 is a foamed silicone sheet.

[0126] The sealing effect between the gasket 6 and the end face of the rotor 9 is further improved by the sealing contact between the gas flow structure 200 and the rotor 9.

[0127] In some embodiments of this application, reference is made to Figure 2 The gas flow structure 200 also includes a buffer pad 7, which is disposed between the sealing end face and the sealing gasket 6. For example, the buffer pad 7 is a PTFE plate.

[0128] By adding a buffer pad 7, the buffering capacity and the amount of compression deformation are increased, which helps to further improve the sealing effect between the gas flow structure 200 and the impeller 9.

[0129] In some embodiments of this application, reference is made to Figure 10 and Figure 11 The rotor 9 device also includes a thrust device configured to apply force to the gas flow structure 200 so that the sealing end face seals against the end face of the rotor 9.

[0130] In other words, the thrust device applies a force to the gas flow structure 200, causing the gas flow structure 200 to move closer to the rotor 9, thereby enabling the gas flow structure 200 to come into close contact with the end side of the rotor 9 to achieve a seal.

[0131] In some embodiments of this application, reference is made to Figure 10 The thrust device includes a first thrust device, which includes a drive unit 310, a force transmission mechanism, and a lead screw. The force transmission mechanism is configured to transmit the power of the drive unit 310 to the lead screw, and the lead screw is connected to the gas flow structure 200.

[0132] Specifically, the drive unit 310 is a motor, which transmits power to the lead screw through a force transmission mechanism. The lead screw rotates, causing the gas flow structure 200 to move toward or away from the end of the rotor 9.

[0133] In some embodiments of this application, reference is made to Figure 10 The force transmission mechanism includes a first steering gear 321, a second steering gear 322, a first elevator 323, a second elevator 324, a first transmission rod 325, and two second transmission rods 326. The first transmission rod 325 extends vertically, and the second transmission rods 326 extend horizontally.

[0134] The first transmission rod 325 connects the first steering gear 321 and the second steering gear 322. One second transmission rod 326 connects the first steering gear 321 and the first elevator 323. The other second transmission rod 326 connects the second steering gear 322 and the second elevator 324. The power shaft of the drive unit 310 is connected to the first steering gear 321. The first elevator 323 is connected to the first lead screw 331. The first lead screw 331 is connected to the top of the gas flow structure 200. The second elevator 324 is connected to the second lead screw 332. The second lead screw 332 is connected to the bottom of the gas flow structure 200.

[0135] The synchronous movement of the upper and lower lead screws is achieved by using a set of motors and force transmission mechanisms, thereby improving the motion reliability of the gas flow structure 200.

[0136] In some embodiments of this application, reference is made to Figure 11 The thrust device also includes a second thrust device, which includes a spring 410. A fixed frame 450 is provided on the side of the gas flow device, and the spring 410 is disposed between the fixed frame 450 and the gas flow device.

[0137] The spring 410 is configured to apply a force to the gas flow structure 200, causing the gas flow structure 200 to tend to move towards the rotating wheel 9, so that the gas flow structure 200 always remains in a sealed state against the end face of the rotating wheel 9, thereby improving the sealing effect.

[0138] In some embodiments of this application, reference is made to Figure 11 and Figure 12 A first fixed seat 420 is provided on the outer wall of the gas flow structure 200, an adjusting bolt 440 is provided on the fixed frame 450, a second fixed seat 430 is provided at the end of the adjusting bolt 440, and a spring 410 is provided between the first fixed seat 420 and the second fixed seat 430.

[0139] The mounting bracket 450 is fixedly installed, and the force exerted by the spring 410 on the gas flow structure 200 is adjusted by turning the adjusting bolt 440.

[0140] In some embodiments of this application, the rotary wheel 9 device further includes a pressure detection device configured to detect the clamping force of the gas flow structure 200. The pressure detection device uploads the pressure detection data to the control system, which adjusts the movement of the drive unit 310 based on the pressure data, so that the lead screw drives the gas flow structure 200 to a suitable position to always maintain a sealed state with the rotary wheel 9.

[0141] In some embodiments of this application, reference is made to Figure 8The rotating wheel 9 device also includes a guide device, which includes a fixed guide part 510 and a movable guide part 520. The movable guide part 520 is disposed on the sealing body 240. The fixed guide part 510 and the movable guide part 520 are slidably connected. The movement direction of the movable guide part 520 is parallel to the axial direction of the rotating wheel 9.

[0142] In other words, when the gas flow structure 200 moves under the action of the thrust device, the movable guide part 520 moves along the fixed guide part 510. Through the sliding connection between the fixed guide part 510 and the movable guide part 520, the reliability and stability of the movement of the gas flow structure 200 are improved.

[0143] For example, the fixed guide part 510 is a fixed guide rail, and the movable guide part 520 is a slider, which is slidably connected to the fixed guide rail.

[0144] In some embodiments of this application, reference is made to Figure 14 A recyclable and reusable adsorption system is provided, comprising: a rotor 9, a nitrogen circulation pipeline, and a desorption and recovery unit. The rotor 9 includes an adsorption zone 401, a purging zone 404, a desorption zone 403, and a cooling zone 402 arranged sequentially along its circumference. Specifically, the rotor 9 is configured to rotate to different working positions to sequentially perform adsorption, purging, desorption, and cooling processes. The aforementioned adsorption zone 401, purging zone 404, desorption zone 403, and cooling zone 402 actually refer to the working processes performed by different areas on the rotor 9 when it moves to different working positions. For ease of understanding of the working processes of the rotor 9, each area is named according to the working process it performs.

[0145] The nitrogen circulation pipeline includes a circulation loop between the cooling zone 402 and the purging zone 404.

[0146] The desorption and recovery unit and the nitrogen circulation pipeline intersect through the first heat exchange device 701 for heat exchange. Meanwhile, each zone of the rotor 9 includes a heat storage material, specifically a mixture of activated carbon and SiC, with an ash content of 25%.

[0147] The desorption and recovery unit includes a desorbed gas outlet pipe P4 and a desorbed gas inlet pipe P13. The desorbed gas outlet pipe P4 is connected upstream to the desorption zone 403 and downstream to a cooling unit. The desorbed gas inlet pipe P13 is connected upstream to a heating unit and downstream to the desorption zone 403. The desorbed gas outlet pipe P4 and the desorbed gas inlet pipe P13 are connected via a condensate gas pipe P7.

[0148] The cooling unit includes a desorption fan 6, a second heat exchange device 702, a condenser 801, and a gas-liquid separator 901, which are connected in sequence on the desorption gas outlet pipeline P4.

[0149] The heating unit includes a first heat exchanger 701, a second heat exchanger 702, and a heater 120 connected in sequence on the desorption gas inlet pipe P13.

[0150] The cooling unit and the heating unit meet through the second heat exchange device 702 to exchange heat.

[0151] The downstream of the gas-liquid separator 901 includes a condensate gas pipeline P7 and a condensate liquid outlet P8. The downstream of the condensate gas pipeline P7 is connected to the heating unit via a first heat exchange device 701.

[0152] On the side of the circulation loop that leaves the purge zone 404 and enters the cooling zone 402, an oxygen concentration detector 501 and a cooling fan 110 are sequentially installed. On the side of the circulation loop that leaves the cooling zone 402 and enters the purge zone 404, a first heat exchange device 701 and a purge fan 130 are sequentially connected.

[0153] The nitrogen circulation pipeline also includes a nitrogen inlet P2 located on the circulation loop, with the nitrogen inlet P2 located on the circulation loop between the cooling fan 110 and the cooling zone 402.

[0154] Adsorption zone 401 includes exhaust gas inlet and emission outlet P3.

[0155] The system also includes a temperature and humidity regulating device 101, a filter 201 and an adsorption fan 301 connected in sequence, with the adsorption fan 301 connected to the exhaust gas inlet.

[0156] Reference Figure 13 The filter 201 includes a frame 2011 and multiple filter bodies 2010. The multiple filter bodies 2010 are arranged sequentially along the height direction within the frame 2011, and there is an angle between adjacent filter bodies 2010. That is, the multiple filter bodies 2010 are arranged in a W-shape, which helps to save space for the same air passage area.

[0157] This application provides an adsorption method based on the aforementioned recyclable and reusable adsorption system:

[0158] Taking the waste gas treatment of a certain printing industry production process as an example, the emission volume is 50,000 Nm³. 3 The air volume is [ / h], the components are ethyl acetate and butyl acetate, and the total concentration of exhaust gas is 2000 mg / m³. 3 The exhaust gas temperature is 50℃ and the relative humidity is 30%. The required exhaust gas concentration after treatment is <30mg / m³. 3 .

[0159] The workshop exhaust gas enters the temperature and humidity control device 101 through the exhaust gas inlet P1, where the temperature is reduced to 35℃, and then enters the filter 201 to remove particulate matter from the exhaust gas. The filtered gas is then sent to the adsorption zone 401 of the rotary wheel 9 by the adsorption fan 301. When the outlet concentration of the adsorption zone 401 is <30mg / m³, the exhaust gas is allowed to pass through the filter. 3 When the exhaust gas meets the emission standards, it is discharged into the atmosphere through the emission outlet P3.

[0160] When the adsorption zone 401 reaches adsorption saturation, the system switches to the purging zone 404. Nitrogen gas is introduced through the nitrogen inlet P2, the purging fan 130 is turned on, and the purging zone inlet gas P11 purifies the purging zone 404. The oxygen concentration of the system is monitored by a two-way oxygen concentration detector 5. When the oxygen concentration reaches the target safety value, the nitrogen protection of the system is turned off.

[0161] Then the rotor rotates from the purging zone 404 to the desorption zone 403, with a desorption air volume of 5000 Nm³. 3 / h, desorption outlet concentration is 200g / m³ 3 The desorbed gas outlet pipe P4 contains a large amount of VOCs and a small amount of moisture. The desorption fan 6 is turned on and the gas is sent to the condenser 801. Circulating water is used for condensation, and the condensation temperature is 10℃. The condensed gas outlet P6 enters the gas-liquid separator 901. The condensed liquid is discharged and collected from the condensed liquid outlet P8. The condensed gas enters the first heat exchange device 701 through the condensed gas pipe P7 and exchanges heat with the cooling zone outlet gas P10. The heat exchange temperature at the outlet P5 of the first heat exchange device is 150℃. Then it passes through the second heat exchange device 702 for heat exchange. The heat exchange temperature at the outlet P12 of the second heat exchange device is 170℃. After two heat exchanges, it enters the heater 120 and is heated to 200℃ before entering the desorption zone 403 again. This process is repeated multiple times until the design requirements are met.

[0162] When the rotor 9 moves from the desorption zone 403 to the cooling zone 402, the gas P9 from the purge zone outlet enters the cooling zone 402, using the heat from the cooling zone 402 as a heat source in the first heat exchanger 701. This raises the temperature of the condensed gas, improves the rotor's thermal efficiency, and recycles the nitrogen replenished in the system. The system's heat exchange efficiency reaches up to 90%, overall system energy consumption is reduced by 60%, and nitrogen consumption is reduced by 80%.

[0163] Depending on the composition and concentration of the waste gas being treated, multiple sealing zones can be set between the adsorption zone 401, purging zone 404, desorption zone 403, and cooling zone 402 of the rotary wheel to ensure that cross-zone operation does not occur during system operation and to improve the processing capacity of the rotary wheel system.

[0164] In some embodiments of this application, a rotary adsorption recovery system is provided, as described above. Figure 1 and Figure 15It includes a rotating device, which comprises a rotating wheel 9 and a gas flow structure 200. The rotating wheel 9 is provided with multiple gas flow channel units 91, which are distributed along the axis of the rotating wheel 9.

[0165] Gas flow structures 200 are provided on opposite ends of the rotor 9, and three chambers 210 for gas flow are provided within the gas flow structures 200. The three chambers 210 are a purge chamber 214, a desorption chamber 215, and a cooling chamber 216. The purge chamber 214, the desorption chamber 215, and the cooling chamber 216 are distributed sequentially around the axis of the rotor 9.

[0166] At least one channel unit 91 is located between two purge chambers 214, at least one channel unit 91 is located between two desorption chambers 215, at least one channel unit 91 is located between two cooling chambers 216, and at least one channel unit 91 is located outside the gas flow structure 200.

[0167] The purge chamber 214 is configured such that inert gas flows through the corresponding channel unit 91 for purging along the airflow direction.

[0168] The desorption chamber 215 is configured such that the inert gas flows through the corresponding channel unit 91 for desorption along the airflow direction.

[0169] Cooling chamber 216 is configured such that inert gas flows through the corresponding channel unit 91 along the airflow direction for cooling. The inert gas is, for example, nitrogen.

[0170] Specifically, the two purge chambers 214 are designated as purge inlet chamber 2141 and purge outlet chamber 2142, the two desorption chambers 215 are designated as desorption inlet chamber 2151 and desorption outlet chamber 2152, and the two cooling chambers 216 are designated as cooling inlet chamber 2161 and cooling outlet chamber 2162. Inert gas flows into the corresponding channel unit 91 through purge inlet chamber 2141 to purge the channel unit, and then flows out through purge outlet chamber 2142. Inert gas flows into the corresponding channel unit 91 through desorption inlet chamber 2151 to desorb from the channel unit, and then flows out through desorption outlet chamber 2152. Inert gas flows into the corresponding channel unit 91 through cooling inlet chamber 2161 to cool the channel unit, and then flows out through cooling outlet chamber 2162.

[0171] The waste gas in the workshop flows through the waste gas inlet P1 and through the adsorption channel unit 91, that is, the waste gas flows through the adsorption zone 401. The adsorption zone 401 adsorbs the organic matter in the waste gas. After adsorption, the waste gas meets the emission standards and is discharged through the emission outlet P3.

[0172] As the rotor 9 rotates, the channel units 91 that have completed adsorption are then purged. Inert gas flows into the corresponding channel unit 91 through the purging inlet chamber 2141, purging the channel units 91 located in the purging zone. Using inert gas for purging helps reduce the oxygen content in the system pipeline, avoiding problems caused by high oxygen content and improving system safety.

[0173] As the rotor 9 rotates, the channel unit 91 that has completed purging undergoes desorption. Inert gas flows into the corresponding channel unit 91 through the desorption inlet chamber 2151 to desorb the channel unit located in the desorption zone.

[0174] As the rotor 9 rotates, the channel unit 91 that has completed desorption is cooled again. Inert gas flows into the corresponding channel unit 91 through the cooling inlet chamber 2161 to cool the channel unit located in the cooling zone. Then, as the rotor 9 rotates, it moves to the adsorption station. This cycle continues, and the rotor 9 continuously performs the adsorption-purging-desorption-cooling process to achieve cyclic desorption.

[0175] The rotary adsorption recovery system also includes a first circulation loop unit 710. (Refer to...) Figure 15 The first circulation loop unit 710 is connected between the purge chamber 214 and the cooling chamber 216, and is configured to purge the channel unit 91 communicating with the purge chamber 214 and cool the channel unit 91 communicating with the cooling chamber 216.

[0176] In other words, the first circulation loop unit 710 is a circulation loop connected between the purge chamber 214 and the cooling chamber 216. The channel unit 91 corresponding to the purge chamber 214 is at a low temperature to achieve low-temperature adsorption. After the rotor 9 completes adsorption, it rotates to the purge station. Inert gas purges the channel unit 91 connected to the purge chamber 214, so the gas flowing out of the purge outlet chamber 2142 is also at a low temperature. The low-temperature gas flowing out of the purge outlet chamber 2142 is then used to cool the channel unit 91 located at the cooling station.

[0177] An inert gas, such as nitrogen, flows through the first circulation loop unit 710. Using an inert gas to purge and cool the rotor 9 helps reduce the oxygen content within the system, thus improving system safety.

[0178] The rotary adsorption recovery system also includes a second circulation loop unit 720. (See reference...) Figure 15 The second circulation loop unit 720 is connected between the two desorption chambers 215, that is, between the desorption inlet chamber 2151 and the desorption outlet chamber 2152, and is configured to desorb the channel unit 91 that communicates with the desorption chamber 215.

[0179] Inert gas, such as nitrogen, flows through the second circulation loop unit 720. The inert gas is used to desorb the rotor 9 in a cyclic manner. The desorbed organic matter can be condensed and recovered, while the inert gas can circulate through the desorption zone 403 to achieve cyclic desorption.

[0180] In some embodiments of this application, reference is made to Figure 15 The second circulation loop unit 720 includes a second circulation pipe I 721. The second circulation pipe I 721 is connected to the desorption outlet chamber 2152, and a cooling unit is provided on the second circulation pipe I 721. The cooling unit is configured to cool the gas in the second circulation pipe I 721.

[0181] Specifically, a desorption fan 601 is installed on the second circulation pipeline I 721 to provide power for gas flow. A cooling unit is also installed in the second circulation pipeline I 721 because the gas flowing out from the desorption station is at a high temperature. The cooling unit cools the high-temperature gas in the second circulation pipeline I 721, achieving the condensation and recovery of the desorbed organic matter. The mixed solvent obtained through cooling and condensation can be recovered through the subsequent separation and recovery unit 600.

[0182] For example, the cooling unit includes a condenser 801 and a gas-liquid separator 901.

[0183] In some embodiments of this application, the second circulation loop unit 720 further includes a second circulation pipe II 722. The second circulation pipe II 722 is connected to the desorption inlet chamber 2151, and a heating unit is provided on the second circulation pipe II 722, which is configured to heat the gas in the second circulation pipe II 722.

[0184] Specifically, after the high-temperature gas in the second circulation pipeline I721 is cooled and condensed, the temperature of the inert gas decreases, and then it is heated by the heating unit to become high-temperature gas. The high-temperature inert gas is then circulated to the desorption zone 403 for use in circulation desorption.

[0185] For example, the heating unit includes a heater 120.

[0186] In some embodiments of this application, the second circulation loop unit 720 further includes a second circulation pipeline Ⅲ 723, which is connected between the cooling unit and the heating unit.

[0187] In some embodiments of this application, reference is made to Figure 15 The first circulation loop unit 710 includes a first circulation pipe I 711 and a first circulation pipe II 712. The first circulation pipe I 711 is connected between the purge outlet chamber 2142 and the cooling inlet chamber 2161, and the first circulation pipe II 712 is connected between the cooling outlet chamber 2162 and the purge inlet chamber 2141.

[0188] The adsorption recovery system also includes a first heat exchange device 701, which is configured to exchange heat between the first circulation pipeline II 712 and the second circulation pipeline II 722, so as to reduce the temperature of the gas flowing into the purge inlet chamber 2141 through the first circulation pipeline II 712 and increase the temperature of the gas flowing into the desorption inlet chamber 2151 through the second circulation pipeline II 722.

[0189] In other words, the gas blown out from the cooling station is at a high temperature, while the gas entering the desorption station is also required to be at a high temperature. Therefore, a first heat exchanger device is installed between the first circulation pipe II 712 and the second circulation pipe II 722 to use the heat in the first circulation pipe II 712 to heat up the second circulation pipe II 722. This achieves heat recovery and utilization, which helps to reduce system energy consumption.

[0190] In some embodiments of this application, reference is made to Figure 15 The adsorption and recovery system also includes a second heat exchange device 702, which is configured to exchange heat between the second circulation pipeline I 721 and the second circulation pipeline II 722 to reduce the gas temperature in the second circulation pipeline I 721 and increase the gas temperature in the first circulation pipeline II 712.

[0191] In other words, the high-temperature gas flowing through the second circulation pipe I 721 is from the channel unit 91 where the desorption process takes place, while the high-temperature gas flowing through the second circulation pipe II 722 is required to desorb the gas entering the channel unit 91 at high temperature. At the same time, the second circulation pipe I 721 needs to be equipped with a cooling unit to condense and cool the gas, so as to condense and recover the desorbed substances. Therefore, a second heat exchange device 702 is set between the second circulation pipe I 721 and the second circulation pipe II 722 to generate heat exchange between the two, thus realizing heat recovery and utilization, which helps to reduce system energy consumption.

[0192] In some embodiments of this application, the first heat exchange device 701 is disposed upstream of the second heat exchange device 702 along the gas flow direction in the second circulation pipeline II 722.

[0193] The low-temperature gas flowing out of the gas outlet of the gas-liquid separator 901 first undergoes a first heat exchange and temperature increase via the first heat exchange device 701, then a second heat exchange and temperature increase via the second heat exchange device 702, and then a third temperature increase via the heater 120, before flowing to the rotor 9 for high-temperature desorption. During the first heat exchange and temperature increase, the cooling energy in the second circulation pipe II 722 cools the first circulation pipe II 712. During the second heat exchange and temperature increase, the cooling energy in the second circulation pipe II 722 cools the second circulation pipe I 721.

[0194] In some embodiments of this application, the cooling unit includes a condenser 801 and a gas-liquid separator 901. Along the gas flow direction in the second circulation pipeline I 721, the condenser 801 is located downstream of the second heat exchange device 702, and the gas-liquid separator 901 is located downstream of the condenser 801. The second circulation pipeline III 723 connects the gas outlet of the gas-liquid separator 901 and the first heat exchange device 701.

[0195] In some embodiments of this application, reference is made to Figure 15 The second circulation loop unit also includes a bypass pipe 724, which connects the second circulation pipe I 721 and the second circulation pipe II 722. Along the gas flow direction, the junction of the bypass pipe 724 and the second circulation pipe II 722 is located upstream of the heater 120. A control valve is installed on the bypass pipe 724 to control the gas flow rate.

[0196] The high-temperature gas in the second circulation pipeline I 721 is divided into two paths. One path flows into the cooling unit (including the second heat exchange device 702, condenser 801 and gas-liquid separator 901 connected in sequence) for cooling and condensation. The other path flows into the bypass pipeline 724 and flows directly to the heater 120 for reheating without cooling. This helps to reduce some of the system's energy consumption.

[0197] In other embodiments of this application, reference is made to... Figure 16 The second circulation pipeline II 722 is connected between the first heat exchange device 701 and the desorption inlet chamber 2151. A heater 120 is installed on the second circulation pipeline II 722. After the second circulation pipeline II 722 undergoes the first heat exchange and temperature rise through the first heat exchange device 701, it undergoes the second heating and temperature rise through the heater 120.

[0198] Figure 16 The system schematic diagram shown is Figure 15 The difference in the system schematic shown is that, Figure 16 In the system schematic diagram shown, the second heat exchange device 702 is a water-cooled heat exchanger, which directly cools the second circulation pipeline I 721 with cold water. The second circulation pipeline II 722 does not pass through the second heat exchange device 702, but is directly heated by the heater 120 to provide high-temperature gas to the desorption inlet chamber 2151.

[0199] In some embodiments of this application, the rotary adsorption recovery system further includes a separation and recovery unit 600. (See also...) Figure 15 and Figure 17 The separation and recovery unit 600 is configured to separate and recover the mixed solvent that has been desorbed from and condensed from the rotor 9 device.

[0200] Specifically, the separation and recovery unit 600 is connected to the second circulation loop unit 720, which includes an evaporator 620 configured to evaporate and vaporize the flowing mixed solvent. The evaporator 620 is connected to the liquid outlet of the gas-liquid separator 901 via a pipeline, on which a solvent pump 610 is installed to provide power for the liquid flow.

[0201] The separation and recovery unit 600 also includes a distillation separation loop 630, which is connected to the evaporator 620 and is configured to perform circulating distillation separation on the flowing mixed solvent to obtain a light component solvent.

[0202] The distillation separation loop 630 includes a supergravity bed 631, a reflux condenser 632 and a reflux pump 633 connected in sequence. The mixed solvent from the evaporator 620 circulates between the supergravity bed 631, the reflux condenser 632 and the reflux pump 633 to achieve distillation separation.

[0203] The separation and recovery unit 600 also includes a module 640, which is connected to the distillation separation loop 630 and is configured to remove water and acid from the flowing light component solvent to obtain the finished organic solvent.

[0204] Module 640 is connected to the reflux condenser 632 and reflux pump 633 through a pipeline. The light component solvent obtained after distillation separation circulation loop 630 flows into module 640, where water and acid are removed by membrane permeation, and the finished organic solvent is obtained, realizing the recovery of desorbed substances.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
