[0024] 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0030] This patent provides a novel rotary adsorption concentration and recovery treatment device with a moving bed structure. By improving the structure of the equipment, the valve switching in the original fixed bed operation process is replaced by rotary wheel switching, which solves the problem of inlet and outlet concentration fluctuation caused by valve switching during adsorption, desorption, and cooling. It is more suitable for the semiconductor and precision machinery industries that require stable exhaust gas.

[0031] Due to limitations in the fixed-bed process and structure, the original fixed-bed system required separate adsorption, desorption, and cooling processes, necessitating at least one separate device. The total air volume consumed during desorption was essentially equal to that during adsorption, resulting in a large scale of utilities and high energy consumption during the desorption process. The rotary desorption device provided in this patent divides the rotary wheel into several sectors, performing continuous desorption only on one sector, significantly reducing energy loss during the desorption process. It is not only energy-saving but also has extremely low initial investment costs, making it more popular in the market.

[0032] In addition, conventional engineering projects are large in scale, with long installation and transportation cycles, extremely complex processes, and difficulty in quality control, resulting in a lack of aesthetics. The complete adsorption treatment device provided by this utility model adopts a skid-mounted integrated design concept, integrating the product into a frame container of the same size, which can be used as soon as it is hoisted. This not only solves the confusion and quality problems during the installation process, but also provides a guarantee for the sealing required for the overall operation of the equipment.

[0033] See Figures 1 to 4 This utility model discloses a rotary adsorption concentration and recovery treatment device, which mainly consists of three parts: an adsorption treatment system A, a condensation recovery system B, and a utility system C. The overall system eliminates the traditional fixed bed method of changing the gas direction by switching valves. The sealing module 15 is directly attached to the adsorption wheel 4. Different waste gases are introduced into the adsorption sector 17 of the wheel, the cooling zone 13 of the sealing module, and the desorption zone 14 of the sealing module, and the gases are isolated. The rotation of the wheel realizes the replacement of different areas of waste gas.

[0034] Two sealing modules 15 are arranged opposite each other on both sides of the adsorption wheel 4. Each sealing module 15 includes a sealing module cooling zone 13 and a sealing module desorption zone 14 arranged sequentially.

[0035] The adsorption treatment system A includes a fan 1, a first condensation and cooling module 2, a filter module 3, and an adsorption rotor 4 connected in sequence. The adsorption rotor 4 includes an adsorption zone, a cooling zone, and a desorption zone. The filter module 3 is located at the inlet of the adsorption zone. The exhaust port of the adsorption zone is connected to the atmosphere. After pretreatment devices such as condensation and cooling and filtration, the exhaust gas reaches the adsorption rotor 4 for adsorption. The gas that meets the adsorption standards after adsorption in the adsorption zone enters the exhaust gas outlet module 5 for discharge. The fan 1 sends the exhaust gas to be adsorbed into the adsorption zone of the adsorption rotor 4.

[0036] The condensation recovery system includes a heating module 6, a recovery module 7, a heat exchange module 9, a power module 12, and a second condensation cooling module 10. The heating module 6 heats the desorption zone. The exhaust port of the desorption zone is connected to the inlet of the heat exchange module 9. The heat exchange module 9 recovers heat from the organic waste gas discharged from the desorption zone. The exhaust port of the heat exchange module 9 is connected to the inlet of the second condensation cooling module 10. The outlet of the second condensation cooling module 10 is connected to the recovery module 7, and the organic waste gas discharged from the outlet of the second condensation cooling module 10 undergoes condensation and separation in the recovery module 7.

[0037] Specifically, the exhaust gas after adsorption by the rotary wheel rotates and reaches the space between two opposing sealed modules 15. At this point, the desorption zone 14 of the sealed module is heated by the heating module 6 to reach a higher temperature, achieving desorption. The desorbed organic waste gas is recycled through the heat exchange module 9, thereby reducing energy consumption and achieving energy conservation and emission reduction. After heat exchange, the exhaust gas is cooled by the condensation module, converting the gaseous state into a liquid state for secondary collection. Finally, under the condensation and separation action of the recovery module 7, it is purified and separated, completing solvent recovery. The power module 12 supplies air to the desorption zone.

[0038] The heat exchange module 9 includes a plate heat exchanger. The exhaust port of the desorption zone is connected to the hot-side inlet of the plate heat exchanger, the hot-side outlet of the plate heat exchanger is connected to the inlet of the second condensation and cooling module 10, the outlet of the second condensation and cooling module 10 is connected to the recovery module 7, the gas outlet of the recovery module 7 is connected to the cold-side inlet of the plate heat exchanger, and the gas entering the cold side exchanges heat with the hot side portion to increase its temperature. The cold-side outlet of the plate heat exchanger is connected to the inlet of the desorption zone.

[0039] The rotary adsorption concentration and recovery treatment unit also includes a utility system. This system comprises a cryogenic module 8, a nitrogen generation module 11, and an industrial control system, providing power and basic support for the system's stable operation. The second condensation and cooling module 10 includes a surface cooler. The cryogenic module 8 cools the external water source before it enters the surface cooler, where it cools, condenses, and recovers the waste gas. The outlet of the nitrogen generation module 11 connects to the adsorption inlet pipeline of the adsorption zone. The nitrogen generation module 11 separates the compressed air in the workshop to produce nitrogen, which serves as a medium for VOCs transmission and is used in the overall pipeline's recycling process. The integration of the utility components also realizes the design concept of a skid-mounted integrated unit, enabling the equipment to operate independently and adapt to various different scenario requirements.

[0040] Furthermore, the rotary adsorption concentration and recovery treatment device includes a first skid-mounted frame and a second skid-mounted frame. The adsorption treatment system is installed on the first skid-mounted frame, and the condensation recovery system is installed on the second skid-mounted frame. The first skid-mounted frame and the second skid-mounted frame can be connected to each other.

[0041] In summary, the rotary adsorption concentration and recovery treatment device provided by this utility model, through improvements in structural design, enables the original engineering project to be skid-mounted, integrated into one unit, and readily available, making it more flexible and versatile, and suitable for different project scenarios.

[0042] This invention, through a combination of a rotary wheel and sector design, replaces the original valve switching method with a sector rotation processing method. This achieves purification of polluted gases while avoiding the peak-and-trough phenomena caused by the new valve switching. The rotary wheel continuously and simultaneously adsorbs and desorbs polluted gases, eliminating the need for equipment shutdown for desorption after granular carbon adsorption saturation. Customers can use this equipment for continuous production, improving production efficiency and bringing greater economic benefits to enterprises. Simultaneously, the treatment of waste gas is more stable and gradual, making it more suitable for high-requirement scenarios such as semiconductors and fine chemicals.

[0043] Compared to existing projects, this invention features a more compact and aesthetically pleasing pipeline system with a smaller equipment size. The equipment can be commissioned and operational before leaving the factory, effectively reducing VOCs leakage and increasing overall purification efficiency. By combining the molecular sieve rotor with sector switching to replace the original multi-tank valve switching, the complexity of the overall piping and electrical control systems is reduced. The frequency of use of flanges, valves, and other components prone to leakage is also reduced, thereby lowering manufacturing difficulty, improving production efficiency, and bringing greater economic benefits to enterprises. Furthermore, compared to fixed-bed systems, the desorption area is reduced, resulting in lower energy consumption for utilities.

[0044] In some embodiments of this application, reference is made to Figure 5 A rotary adsorption recovery device is provided, including an adsorption treatment module K1. The adsorption treatment module K1 includes a rotor 4, which is configured to adsorb and desorb flowing organic waste gas.

[0045] Specifically, refer to Figure 4 The rotor 4 is provided with multiple channel units for gas flow, and the multiple channel units are distributed around the axis of the rotor 4. As the rotor 4 rotates, the waste gas flows through the corresponding channel unit for adsorption treatment, the inert gas flows through the corresponding channel unit for desorption treatment, and the cold gas flows through the corresponding channel unit for cooling treatment.

[0046] Sealing modules 15 are respectively provided on opposite ends of the rotor 4. Each sealing module 15 contains two chambers for gas flow. The two chambers are a desorption chamber and a cooling chamber, respectively. The desorption chamber and the cooling chamber are distributed sequentially around the axis of the rotor 4. At least one channel unit is located between the two desorption chambers, at least one channel unit is located between the two cooling chambers, and at least one channel unit is located outside the sealing module.

[0047] The desorption chamber is configured such that the inert gas flows through the corresponding channel unit in the direction of the airflow for desorption. The cooling chamber is configured such that the inert gas flows through the corresponding channel unit in the direction of the airflow for cooling. The inert gas is, for example, nitrogen.

[0048] Specifically, the two desorption chambers are a desorption inlet chamber 210 and a desorption outlet chamber 220, and the two cooling chambers are a cooling inlet chamber 230 and a cooling outlet chamber 240. Inert gas flows into the corresponding channel unit through the desorption inlet chamber 210, where it is desorbed, and then flows out through the desorption outlet chamber 220. Inert gas flows into the corresponding channel unit through the cooling inlet chamber 230, where it is cooled, and then flows out through the cooling outlet chamber 240.

[0049] The waste gas in the workshop flows through the waste gas inlet and then through the adsorption channel unit, that is, the waste gas flows through the adsorption zone. The adsorption zone adsorbs the organic matter in the waste gas. After adsorption, the waste gas meets the emission standards and is discharged through the emission outlet.

[0050] As the rotor 4 rotates, the channel units that have completed adsorption undergo desorption. Inert gas flows into the corresponding channel unit through the desorption inlet chamber 210 to desorb the channel units located in the desorption zone.

[0051] As the rotor 4 rotates, the channel unit that has completed desorption is cooled again. Inert gas flows into the corresponding channel unit through the cooling inlet chamber 230 to cool the channel unit located in the cooling zone. Then, as the rotor 4 rotates, it moves to the adsorption station. This cycle continues, and the rotor 4 continuously performs the adsorption-desorption-cooling process to achieve cyclic desorption.

[0052] The aforementioned adsorption zone, desorption zone, and cooling zone actually refer to the working processes performed by different areas on the rotor 4 when it moves to different working positions. To facilitate understanding of the working process of the rotor 4, each area is named according to the working process it performs.

[0053] The rotary adsorption recovery device also includes a condensation recovery module K2. The condensation recovery module K2 is configured to condense, separate, and recover the organic waste gas after it has been desorbed by the rotor 4.

[0054] The rotary adsorption recovery device also includes a first skid-mounted frame M1 and a second skid-mounted frame M2. The adsorption processing module K1 is mounted on the first skid-mounted frame M1. The condensation recovery module K2 is mounted on the second skid-mounted frame M2.

[0055] The first skid-mounted frame M1 is docked with the second skid-mounted frame M2 so that the adsorption treatment module K1 is docked with the condensation recovery module K2.

[0056] In existing technologies, the functional modules and piping of rotary adsorption recovery devices need to be assembled on-site, resulting in complex and time-consuming installation. This application addresses this by using a first skid-mounted frame M1 and a second skid-mounted frame M2. The adsorption treatment module K1 is integrated onto the first skid-mounted frame M1, and the condensation recovery module K2 is integrated onto the second skid-mounted frame M2. Pre-assembly of internal components, piping connections, and commissioning can be completed in the factory. At the customer's site, only the first skid-mounted frame M1 and the second skid-mounted frame M2 need to be connected for rapid connection between the adsorption treatment module K1 and the condensation recovery module K2. This design significantly reduces the workload and complexity of on-site installation, effectively shortens the installation cycle, reduces reliance on specialized personnel skills for on-site installation, and improves the efficiency and reliability of device installation.

[0057] The adsorption treatment module K1 and the condensation recovery module K2 are integrated using a skid-mounted frame, making the structure of each module more compact and reducing the number of scattered parts. This integrated design not only optimizes the spatial layout of the unit at the customer's site and saves installation space, but also facilitates unified management and operation of each module in production, transportation, and installation, improving the practicality and convenience of the entire unit.

[0058] Since the adsorption treatment module K1 and the condensation recovery module K2 have been pre-assembled and debugged in the factory, the connections between the components are more precise and reliable, reducing potential errors and malfunctions that may arise from on-site assembly. This helps ensure the stability and processing efficiency of the unit during operation. Furthermore, the modular design allows for operation on specific modules when the unit malfunctions or requires maintenance, eliminating the need to disassemble the entire unit. This reduces maintenance difficulty, shortens maintenance time, and improves the convenience and lifespan of the unit.

[0059] The docking connection between the first skid-mounted frame M1 and the second skid-mounted frame M2 allows for flexible combination and disassembly of the adsorption treatment module K1 and the condensation recovery module K2 according to actual application requirements. This enables easy adjustment of the unit's configuration to handle different scales of waste gas treatment tasks or varying site conditions, enhancing the unit's adaptability and flexibility. Furthermore, this modular structure facilitates subsequent upgrades and expansions, allowing for the addition of new modules or the modification of existing modules to meet evolving treatment needs.

[0060] In some embodiments of this application, the rotary adsorption recovery device further includes a separation and recovery module K3, which is configured to separate and recover the organic solvent condensed and recovered from the condensation and recovery module K2.

[0061] Figure 9This is a schematic diagram of a separation and recovery module. Specifically, the separation and recovery module K3 includes an evaporator 620, which is configured to evaporate and vaporize the flowing mixed solvent. The evaporator 620 is connected to a condensation recovery module via piping, and a solvent pump 610 is installed on the piping to provide power for the liquid flow.

[0062] The separation and recovery module K3 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.

[0063] 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.

[0064] The separation and recovery module K3 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.

[0065] 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.

[0066] Reference Figure 5 The rotary adsorption recovery device also includes a third skid-mounted frame M3, on which the separation and recovery module K3 is mounted. Mounting the separation and recovery module K3 on the third skid-mounted frame M3 continues the skid-mounted design concept of the preceding modules. In the factory, the installation of internal components, piping connections, and commissioning of the separation and recovery module K3 can be completed in advance. When on-site installation is required, the third skid-mounted frame M3 is simply connected to the second skid-mounted frame M2, which carries the condensation recovery module K2, to achieve rapid integration of the separation and recovery module K3 with the entire device. This design further simplifies the on-site installation process, especially in scenarios involving large-scale processing and multiple modules working collaboratively. Each skid-mounted frame can be transported to the site separately and then connected sequentially, reducing the requirements for on-site installation space and lifting equipment, and significantly improving the flexibility and convenience of installation.

[0067] Meanwhile, the inclusion of the third skid-mounted frame M3 enhances the scalability of the unit. In practical applications, different customers may have varying requirements for organic solvent separation; some may only require condensation and recovery, while others require higher purity separation products. By independently mounting the separation and recovery module K3 on the third skid-mounted frame M3, customers can choose whether to configure this module based on their specific needs, achieving personalized customization of the unit. Furthermore, if subsequent customer processing requirements change and require the addition of separation and recovery functionality, this can also be achieved by separately installing the third skid-mounted frame M3 and the separation and recovery module K3, without requiring large-scale modifications to the original unit's main structure, thus reducing upgrade costs and complexity.

[0068] In addition, this modular skid-mounted design also facilitates the maintenance and repair of the unit. When the separation and recovery module K3 malfunctions, the module on the third skid-mounted frame M3 can be repaired or replaced separately without affecting the normal operation of other parts such as the condensation recovery module K2 and the adsorption treatment module K1, thus reducing the downtime of the unit and improving the continuous operation efficiency of the equipment.

[0069] In some embodiments of this application, the rotary adsorption recovery device further includes a first skid-mounted connecting box M6, which is configured to connect the second skid-mounted frame M2 and the third skid-mounted frame M3. The first skid-mounted connecting box M6 also serves as a maintenance access channel.

[0070] The first skid-mounted connection box M6 provides a stable and reliable connection structure for the docking of the two frames. During actual installation, there is no need for complex alignment and fixing operations on the second skid-mounted frame M2 (carrying the condensate recovery module K2) and the third skid-mounted frame M3 (carrying the separation and recovery module K3); precise docking can be achieved simply through the first skid-mounted connection box M6. This connection method not only ensures the sealing and stability of the piping and wiring connections between the two modules, reducing leaks and malfunctions caused by improper connections, but also simplifies the on-site installation steps, further shortening installation time and improving installation efficiency.

[0071] Meanwhile, the first skid-mounted connection box M6 also plays an important role as a maintenance access point. During the operation of the unit, when it is necessary to inspect or maintain the condensation recovery module K2 or the separation recovery module K3, staff can conveniently reach the maintenance area of ​​the corresponding module through the first skid-mounted connection box M6.

[0072] In some embodiments of this application, reference is made to Figure 5The rotary adsorption and recovery device further includes a utility module K4, a fourth skid-mounted frame M4, and a second skid-mounted connection box M7. The utility module K4 is mounted on the fourth skid-mounted frame M4. The second skid-mounted connection box M7 is configured to connect the fourth skid-mounted frame M4 to either the third skid-mounted frame M3 or the second skid-mounted frame M2. The second skid-mounted connection box M7 also serves as a maintenance access channel.

[0073] For example, when the rotary adsorption recovery device is configured in separation recovery mode, the second skid-mounted connecting box M7 is configured to connect the fourth skid-mounted frame M4 to the third skid-mounted frame M3. As another example, when the rotary adsorption recovery device is not configured in separation recovery mode, the second skid-mounted connecting box M7 is configured to connect the fourth skid-mounted frame M4 to the second skid-mounted frame M2.

[0074] The utility module K4 is mounted on the fourth skid-mounted frame M4, continuing the overall skid-mounted design of the unit. The utility module K4 typically provides essential auxiliary support for the operation of the entire unit, such as critical guarantees for power, energy, and water resources. Integrating it within the fourth skid-mounted frame M4 allows for pre-installation, commissioning, and pipeline connections of internal components at the factory, ensuring the stability and reliability of the module's operation. This integrated design not only reduces fragmented work during on-site installation but also ensures precise interfacing between the utility module K4 and other functional modules through standardized production, laying the foundation for efficient collaborative operation of subsequent modules.

[0075] The second skid-mounted connecting box M7, as a connecting component, offers selectable connections, significantly enhancing the flexibility and adaptability of the device. When the rotary adsorption recovery device is configured in separation and recovery mode, the second skid-mounted connecting box M7 connects the fourth skid-mounted frame M4 to the third skid-mounted frame M3, enabling the utility module K4 to provide continuous and stable utility support to the separation and recovery module K3 and its associated condensation recovery module K2, ensuring the smooth operation of the entire separation and recovery process. Conversely, when the device is not configured in separation and recovery mode, the second skid-mounted connecting box M7 connects the fourth skid-mounted frame M4 to the second skid-mounted frame M2, ensuring that the utility module K4 directly powers the core modules such as the condensation recovery module K2 and the adsorption treatment module K1, meeting basic waste gas adsorption and condensation recovery requirements. This switchable connection method allows the device to flexibly adjust module combinations according to different application scenarios and treatment needs without requiring large-scale modifications to the overall structure of the device, significantly reducing equipment adaptation costs and broadening the device's applicability.

[0076] Meanwhile, the second skid-mounted connection box M7 serves as a maintenance access point, further improving the unit's maintenance system. During unit operation, personnel can conveniently access the maintenance areas corresponding to the utility module K4, the third skid-mounted frame M3 (when configured with separation and recovery mode), or the second skid-mounted frame M2 (when not configured with separation and recovery mode) via the second skid-mounted connection box M7.

[0077] In other embodiments of this application, reference is made to... Figure 6 The rotary adsorption recovery device includes an adsorption recovery module K5, which comprises an adsorption treatment module K1 and a condensation recovery module K2. The adsorption treatment module K1 includes a rotor 4, configured to adsorb and desorb flowing organic waste gas. The condensation recovery module K2 is configured to condense and recover the organic waste gas after desorption by the rotor 4.

[0078] The rotary adsorption and recovery device also includes a utility module K4, a fifth skid-mounted frame M5, and a fourth skid-mounted frame M4. The adsorption and recovery module K5 is mounted on the fifth skid-mounted frame M5. The utility module K4 is mounted on the fourth skid-mounted frame M4. The fifth skid-mounted frame M5 and the fourth skid-mounted frame M4 are connected to each other, thereby connecting the adsorption and recovery module K5 to the utility module K4.

[0079] Figure 6 In the illustrated embodiment, when the size of the adsorption recovery module K5 is small, the adsorption treatment module K1 and the condensation recovery module K2 can be integrated into a skid-mounted structure. Figure 5 In the illustrated embodiment, when the size of the adsorption recovery module K5 is large, the adsorption treatment module K1 and the condensation recovery module K2 can be respectively set in independent skid-mounted structures.

[0080] The adsorption and recovery module K5 integrates the adsorption treatment module K1 and the condensation recovery module K2 into one unit. This design fully considers the differences in module size under different application scenarios. When the adsorption and recovery module K5 is small, integrating both on the fifth skid-mounted frame M5 can simplify the device structure to the greatest extent and reduce the number of skid-mounted frames. In this case, after the rotor 4 of the adsorption treatment module K1 adsorbs and desorbs the flowing organic waste gas, the desorbed organic waste gas can directly enter the condensation recovery module K2 in the same frame for condensation and separation recovery. This shortens the pipeline connection distance between modules, reduces the risk of waste gas loss or leakage due to excessively long pipelines, and improves the efficiency of the entire adsorption and recovery process. When the adsorption and recovery module K5 is large, as shown in the embodiment in Figure 5 above, the adsorption treatment module K1 and the condensation recovery module K2 are set in independent skid-mounted structures. This avoids the inconvenience caused by the excessive size of a single frame in transportation and installation, demonstrating the flexibility and adaptability of the device in structural design.

[0081] The docking connection between the fifth skid-mounted frame M5 and the fourth skid-mounted frame M4 enables a rapid and stable connection between the adsorption recovery module K5 and the utility module K4. In the factory, the installation of components, piping connections, and commissioning of the adsorption recovery module K5 on the fifth skid-mounted frame M5, as well as the preparation work for the utility module K4 on the fourth skid-mounted frame M4, can be completed in advance. During on-site installation, simply docking the two frames completes the connection between the adsorption recovery module K5 and the utility module K4, significantly reducing the workload and time required for on-site installation. This docking method ensures smooth energy and material transfer between the two modules. For example, the utility module K4 can stably provide the power and energy required for the operation of the adsorption recovery module K5, ensuring the continuous and stable operation of the adsorption treatment and condensation recovery processes.

[0082] In some embodiments of this application, reference is made to Figure 6 The rotary adsorption and recovery device also includes a third skid-mounted connecting box M8, which connects the fourth skid-mounted frame M4 and the fifth skid-mounted frame M5.

[0083] In some embodiments of this application, Figure 6 In the illustrated embodiment, the rotary adsorption recovery device further includes a separation and recovery module K3 and a third skid-mounted frame M3, wherein the separation and recovery module K3 is disposed on the third skid-mounted frame M3.

[0084] The rotary adsorption and recovery device further includes a first skid-mounted connecting box M6 and a second skid-mounted connecting box M7. The first skid-mounted connecting box M6 is configured to connect the fifth skid-mounted frame M5 and the third skid-mounted frame M3. The second skid-mounted connecting box M7 is configured to connect the fourth skid-mounted frame M4 and the third skid-mounted frame M3.

[0085] The function of setting the separation and recycling module K3 on the third skid frame M3 and the skid connection box can be referred to the previous text and will not be repeated here.

[0086] In some embodiments of this application, reference is made to Figures 1 to 3 The condensation recovery module K2 includes a heating module 6, a recovery module 7, a heat exchange module 9, and a second condensation cooling module 10. The heating module 6 heats the channel unit (i.e., the desorption zone) where the desorption process is performed. The exhaust port of the channel unit (i.e., the desorption zone) is connected to the inlet of the heat exchange module 9, which recovers heat from the organic waste gas desorbed by the channel unit. The exhaust port of the heat exchange module 9 is connected to the inlet of the second condensation cooling module 10, and the outlet of the second condensation cooling module 10 is connected to the recovery module 7. The organic waste gas discharged from the outlet of the second condensation cooling module 10 is condensed and separated in the recovery module 7.

[0087] The heating module 6 provides necessary heat support to the channel unit of the desorption zone of the rotor 4. During the desorption process, the heating module 6 heats the desorption zone, effectively increasing the temperature within the channel unit and causing the organic waste gas molecules adsorbed by the rotor 4 to detach from the adsorbent surface, thus enhancing the desorption effect. This process ensures that the organic waste gas adsorbed on the rotor 4 is fully desorbed, providing sufficient treatment targets for subsequent condensation and recovery, avoiding waste gas residue due to incomplete desorption, and improving the overall efficiency of the device in treating organic waste gas.

[0088] The exhaust port of the channel unit performing the desorption process is connected to the inlet of the heat exchange module 9. After the desorbed high-temperature organic waste gas enters the heat exchange module 9, the heat it carries is effectively recovered. This recovered heat can be used to preheat the waste gas to be treated or to support other processes that require heat energy, reducing the device's consumption of external energy, realizing energy recycling, and lowering operating costs. At the same time, the organic waste gas cooled by the heat exchange module 9 enters the subsequent condensation and cooling module, which also reduces the cooling load of the second condensation and cooling module 10 and improves the overall energy efficiency of the condensation system.

[0089] The cooperation between the second condensation and cooling module 10 and the recovery module 7 further improves the recovery efficiency and purity of organic solvents. After the organic waste gas discharged from the heat exchange module 9 enters the second condensation and cooling module 10, it is further cooled, causing the organic components to reach the condensation temperature and transform into a liquid state. Subsequently, the liquid organic solvent enters the recovery module 7 for condensation and separation, achieving effective recovery of useful components from the organic waste gas. This staged condensation method, compared to a single condensation process, can more thoroughly separate the condensable components from the organic waste gas, improving the purity and recovery rate of the recovered materials, reducing the emission of volatile organic compounds, and meeting environmental protection requirements.

[0090] Furthermore, the orderly connection between the modules forms a complete condensation and recovery process, ensuring that the desorbed organic waste gas can flow efficiently along the preset path, avoiding waste gas leakage or treatment interruption. The heating module 6, heat exchange module 9, second condensation and cooling module 10, and recovery module 7 have clear division of labor and work together to ensure that the condensation and recovery module K2 is stable and reliable during operation, adapting to the treatment needs of organic waste gas with different concentrations and compositions, and enhancing the applicability and treatment effect of the entire rotary adsorption and recovery device.

[0091] In some embodiments of this application, the heat exchange module 9 includes a plate heat exchanger. The exhaust port of the channel unit (i.e., the desorption zone) performing the desorption process is connected to the hot-side inlet of the plate heat exchanger, the hot-side outlet of the plate heat exchanger is connected to the inlet of the second condensation cooling module 10, the outlet of the second condensation cooling module 10 is connected to the recovery module 7, the gas outlet of the recovery module 7 is connected to the cold-side inlet of the plate heat exchanger, the gas entering the cold side exchanges heat with the hot side portion and is heated, and the cold-side outlet of the plate heat exchanger is connected to the inlet of the channel unit (i.e., the desorption zone) performing the desorption process.

[0092] Plate heat exchangers offer highly efficient heat exchange performance. High-temperature organic waste gas discharged from the channel unit (desorption zone) performing the desorption process enters the hot side of the plate heat exchanger, where it undergoes thorough heat exchange with gas from the gas outlet of recovery module 7 and into the cold side. The structural characteristics of the plate heat exchanger result in a large contact area and a short heat transfer path between the high-temperature gas on the hot side and the low-temperature gas on the cold side, enabling rapid heat transfer and significantly improving heat recovery efficiency. After releasing heat on the hot side, the high-temperature organic waste gas cools down, making it easier to cool and condense when entering the second condensation and cooling module 10, thus reducing the energy consumption of the second condensation and cooling module 10. Meanwhile, the gas on the cold side absorbs heat and heats up, creating favorable conditions for its subsequent entry into the desorption zone.

[0093] The gas discharged from the gas outlet of recovery module 7 is typically at a low temperature. It is introduced into the cold side of a plate heat exchanger, where it heats up by exchanging heat with the high-temperature gas on the hot side. The heated gas is then sent from the cold-side outlet of the plate heat exchanger to the inlet of the desorption zone. This warmed gas entering the desorption zone reduces the heating energy consumption of heating module 6, as the gas itself carries some heat, thus lowering the energy required to reach the desorption temperature. This cycle fully utilizes the residual heat of the high-temperature organic waste gas after desorption, achieving cascaded energy utilization and significantly reducing the overall operating energy consumption of the device, meeting the requirements for energy conservation and emission reduction.

[0094] The high-temperature gas discharged from the desorption zone is cooled by the plate heat exchanger, and its temperature is more stable when it enters the second condensation and cooling module 10. This avoids the condensation effect being affected by excessive temperature fluctuations, ensuring the condensation and separation efficiency of the organic solvent by the recovery module 7. At the same time, the gas entering the desorption zone is heated by the plate heat exchanger, resulting in a more stable temperature. This reduces the load fluctuation of the heating module 6, which is conducive to the stable operation of the heating module 6. In turn, it ensures the stable desorption effect in the desorption zone, ensuring that the organic waste gas on the rotor 4 can be continuously and fully desorbed.

[0095] In some embodiments of this application, the rotary adsorption recovery device further includes a utility module K4, which includes a cryogenic module 8. The second condensation and cooling module 10 includes a surface cooler; the cryogenic module 8 cools the external water source before it enters the surface cooler.

[0096] The cryogenic module 8 cools the external water source to an even lower temperature, providing a low-temperature cooling medium for the surface cooler. When the organic waste gas, after being treated by the heat exchange module 9, enters the surface cooler, a larger temperature difference is created between the low-temperature cooling medium and the organic waste gas. This allows for faster and more efficient absorption of heat from the organic waste gas, causing the condensable components in the organic waste gas to condense rapidly into a liquid state. Compared to cooling methods using conventional temperature water sources, this design significantly improves the condensation efficiency and recovery rate of the organic waste gas, reduces the emission of uncondensed organic waste gas, further enhances the treatment effect of the device on organic waste gas, and meets more stringent environmental protection requirements.

[0097] The cryogenic module 8 can flexibly adjust the output cooling medium temperature according to the actual operating conditions such as the composition, concentration, and treatment volume of the organic waste gas. When treating high-boiling-point or high-concentration organic waste gas, the cryogenic module 8 can lower the cooling medium temperature to ensure that such organic waste gas can be fully condensed; while when treating low-boiling-point or low-concentration organic waste gas, the cooling medium temperature can be appropriately increased to reduce the energy consumption of the cryogenic module 8 while ensuring the condensation effect. This adjustability allows the device to adapt to the treatment needs of different types of organic waste gas, enhancing the versatility and flexibility of the device.

[0098] The cryogenic module 8, as part of the utility module K4, is mounted on the fourth skid-mounted frame M4. The surface cooler, as a component of the second condensing cooling module 10, is integrated into the corresponding skid-mounted frame. The two are connected by piping, facilitating pre-installation and commissioning at the factory and reducing the complexity of on-site installation. Meanwhile, the surface cooler features a simple structure, large heat exchange area, and ease of maintenance. When used in conjunction with the cryogenic module 8, the entire cooling system operates stably and reliably, reducing equipment failure rates, minimizing maintenance workload, and enhancing the continuous operation capability of the unit.

[0099] In some embodiments of this application, reference is made to Figure 7 and Figure 8 The top of the skid-mounted frame includes a plurality of top plates 110 arranged sequentially. In two adjacent top plates 110, one top plate 110 is provided with an upwardly extending first vertical plate 111, and the top of the first vertical plate 111 is provided with a horizontally extending first horizontal plate 112; the other top plate 110 is provided with an upwardly extending second vertical plate 113, the top of the second vertical plate 113 is provided with a horizontally extending second horizontal plate 114, and the side of the second horizontal plate 114 is provided with a downwardly extending third vertical plate 115.

[0100] When two adjacent top rods are joined, the first vertical plate 111 and the second vertical plate 113 are abutted together, the second horizontal plate 114 is abutted against and covers the first horizontal plate 112, and the third vertical plate 115 is located beside the first horizontal plate 112. Sealant is applied between the first vertical plate 111 and the second vertical plate 113, and between the first horizontal plate 112 and the second horizontal plate 114, to achieve waterproofing and prevent water leakage from the top of the skid-mounted frame. Furthermore, the overlapping structure between two adjacent top plates 110 facilitates pre-positioning during installation.

[0101] In some embodiments of this application, reference is made to Figure 8 An inclined plate 116 is provided on the circumferential side of the top plate 110, the inclined plate 116 facing the outside of the skid frame and extending downward. The inclined plate 116 serves as a dustproof function, preventing fallen leaves and other debris from the top from falling onto the side wall of the skid frame and then entering the interior of the skid frame through the heat dissipation vent 120.

[0103] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto.
