Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0028] To address the lack of a mechanism in existing technologies for recovering coatings from waste gas, this application provides a material recovery system. This system utilizes a concentration-separated pipeline structure, with first and second pipelines respectively delivering high-concentration and low-concentration material gases. High-concentration gas is directly connected to the first recovery module for priority recovery, while low-concentration gas is refluxed and heated. This avoids dilution of recovery efficiency caused by mixing gases of different concentrations, achieving "precise diversion-targeted recovery" and laying a structural foundation for efficient recovery. Simultaneously, the series connection of the first and second recovery modules forms a stepped recovery path of primary and multi-stage recovery, compensating for the incomplete treatment of low-concentration gas by a single recovery module. The system significantly improves the integrity of material recycling. Furthermore, the container module, with its dual input terminals directly connecting to the two recycling modules, enables centralized collection of recycled materials, avoiding losses and pollution caused by dispersed collection and simplifying subsequent processing. Additionally, the closed-loop structure formed by the heating module, material volatilization module, and second recycling module allows for the recirculation and heating of low-concentration incoming gas, reducing energy waste. Finally, the exhaust gas treatment module, as the final connection structure, precisely connects to the third output terminal of the second recycling module, ensuring that unrecovered exhaust gas is treated before emission, structurally blocking pollution pathways. Ultimately, through the functional zoning and close connection of each module, efficient material recycling is achieved while avoiding environmental pollution.

[0029] The material recycling system provided in this application will be further explained and described below with reference to the accompanying drawings and specific embodiments. The embodiments do not constitute a limitation on the embodiments of this application.

[0030] See Figure 1 This is a schematic diagram of a material recycling system provided in an embodiment of this application. Figure 1 As shown, the material recycling system 10 may include: a material volatilization module 11, a first recycling module 12, a second recycling module 13, a container module 14, a heating module 15, and a waste gas treatment module 16.

[0031] The aforementioned material evaporation module 11 refers to a module capable of outputting gas containing volatile materials. These volatile materials may include, but are not limited to, industrial solvents, coatings, and chemical raw materials. Optionally, the material evaporation module 11 may be a coating machine baking platform. During the baking process of the coating, this platform generates waste gas containing the coating material, which serves as the material gas in the technical solution of this application.

[0032] Furthermore, the material evaporation module 11 can output material gases of different concentrations, such as a first material gas with a material concentration greater than a preset concentration threshold, and a second material gas with a material concentration less than or equal to the preset concentration threshold.

[0033] The aforementioned first recovery module 12 refers to a module used for preliminary material recovery of the first material gas output from the material evaporation module 11. Optionally, the first recovery module 12 can be a heat exchanger to achieve the purpose of material recovery by cooling and condensing the received material into a liquid, such as a stainless steel finned heat exchanger.

[0034] The aforementioned second recovery module 13 is used to perform multi-stage material recovery on the material gas output from the first recovery module 12 after preliminary recovery, thereby increasing the recovery efficiency. Optionally, the aforementioned second recovery module 13 can perform multi-stage material recovery on the received material gas. It can be a heat recovery evaporation-condensation unit, or other types of modules capable of multi-stage material recovery. This application embodiment does not limit this.

[0035] The aforementioned container module 14 refers to a module used for storing recycled materials, which may be liquids containing such materials. Optionally, the container module 14 may include at least one container sub-module, for example, it may include one or more water storage tanks.

[0036] The aforementioned heating module 15 refers to a module for heating gas. Since the material evaporation module 11 requires high-temperature gas during operation (for example, when the material evaporation module 11 is a coating machine baking platform, high-temperature gas is required to dry the coating), the gas must be heated by the heating module 15 before it is input into the material evaporation module 11.

[0037] The aforementioned waste gas treatment module 16 refers to a module used to treat the final waste gas after multiple material recycling processes. By treating the waste gas through the waste gas treatment module 16, it is possible to prevent the waste gas from leaking into the air and causing air pollution.

[0038] Furthermore, the aforementioned material volatilization module 11 may include: a first input terminal I 11 and the first output terminal O 11 .

[0039] Furthermore, the aforementioned first recycling module 12 may include: a first input terminal I 21 First output terminal O 21 and the second output terminal O 22 .

[0040] Furthermore, the aforementioned second recycling module 13 may include: a first input terminal I 31 First output terminal O 31 Second output terminal O 32 and the third output terminal O 33 .

[0041] Furthermore, the container module 14 described above may include: a first input terminal I 41 Second input terminal I 42 .

[0042] Furthermore, the heating module 15 may include: a first input terminal I 51 and the first output terminal O 52 .

[0043] Furthermore, the aforementioned waste gas treatment module 16 may include: a first input terminal I 61 .

[0044] In this embodiment of the application, based on the above-described structure of the material recycling system 10, the modules can be connected in the following ways: The first output terminal O of the aforementioned material volatilization module 11 11 The first input terminal I of the first recycling module 12 is connected through the first pipe p1. 21 And the first input terminal I51 of the heating module 15 is connected through the second pipe p2, wherein the first pipe p1 is used to transport the first material gas output by the material volatilization module 11, the second pipe p2 is used to transport the second material gas output by the material volatilization module, and the material concentration of the first material gas is greater than the material concentration of the second material gas.

[0045] Through this connection method, two different concentrations of material gas output from the material volatilization module 11 can be transmitted through different pipelines (the first pipeline transmits the first concentration of material gas, and the second pipeline transmits the second concentration of material gas). This allows the lower concentration of the second concentration of material gas to be returned to the material volatilization module 11 for reuse, and the higher concentration of the second concentration of material gas to be initially recovered through the first recovery module 12.

[0046] The first output terminal O of the first recycling module 12 mentioned above 21 The first input terminal I of the second recycling module 13 can be connected. 31 The second output terminal O of the aforementioned first recycling module 12 31 The first input terminal I of the container module 14 can be connected 41 Among them, the second output terminal O of the aforementioned first recycling module 12 22 It can be used to recover recycled material liquid into container module 14.

[0047] In this connection method, the first recovery module 12 can perform preliminary recovery of the received first-concentration material gas. This recovery process may include heat exchange on the first-concentration material gas, thereby causing the first-concentration material gas to condense into a liquid, and then outputting it through the second output terminal O. 22The recovered liquid material is fed into container module 14. It should be noted that the recovered liquid material in this application can be a liquid containing a portion of the material, such as a liquid with a material concentration of 70%.

[0048] The first output terminal O of the aforementioned second recovery module 13 31 Connect the second input terminal I of container module 14 42 The second output terminal O of the aforementioned second recovery module 13 32 The first input terminal I of the heating module 15 is connected 51 The third output terminal O of the aforementioned second recovery module 13 33 The first input terminal I of the exhaust gas treatment module 16 is connected. 61 Among them, the first output terminal O of the aforementioned second recycling module 13 31 It can be used to recover the material liquid after multi-stage recycling to the container module 14, and the second output terminal O of the second recycling module 13 is described above. 32 The third output terminal O of the second recovery module 13 mentioned above can be used to output fresh gas. 33 It can be used to output the waste gas obtained after multi-stage recovery of the third material gas input to the first recovery module. The material concentration of the newly introduced gas can be lower than a preset value, where the preset value indicates a lower material concentration. When the material concentration of the newly introduced gas is lower than this preset value, it indicates that the newly introduced gas does not contain or contains a reduced amount of material to be recovered.

[0049] In this connection method, the second recovery module 13 can receive the third material gas obtained after the first recovery module 12 has performed preliminary recovery, and perform multi-stage material recovery on the third material gas. During this process, the second recovery module 13 can recover the material by cooling it to obtain condensed material liquid. Afterwards, the recovered material liquid can be recycled into the container module 14, and then the remaining waste gas after the recovery is completed is treated by the waste gas treatment module.

[0050] Furthermore, in order to replenish the gas in the system, the second recovery module 13 can also absorb new gas. The new gas can be a new gas input module or fresh air that has not been treated by the system. This application embodiment does not limit this.

[0051] Based on this, the second recovery module 13 can utilize the second output terminal O 32 The incoming gas is fed into the heating module 15 for heating, and then fed into the material volatilization module 11 for use.

[0052] The first output terminal O of the aforementioned heating module 15 51 The first input terminal I of the connectable material volatilization module 11 11 .

[0053] Through this connection, the heating module 15 can be used to mix and heat the received new gas and the second material gas with a lower material concentration, and then the mixed gas heated to a first temperature value (e.g., 120°C) can be input into the mixed material module 11 for use.

[0054] This completes the work. Figure 1 Structural description of the material recycling system shown.

[0055] based on Figure 1 The material recovery system shown has the following material gas recovery process: the material volatilization module 11 can output material gas at a second temperature value (e.g., 110°C), which can be divided into two layers: a first material gas with a higher concentration (material concentration higher than a preset concentration threshold) at the lower layer and a second material gas with a lower concentration (material concentration lower than a preset concentration threshold) at the upper layer.

[0056] Subsequently, the first material gas can be input into the first recovery module 12 through the first pipe p1 for material recovery, and the second material gas can be input into the heating module 15 through the second pipe p2 to mix and heat with the newly introduced gas.

[0057] Based on this, after receiving the input first material gas, the first recovery module 12 can perform heat exchange treatment on the first material gas to condense a portion of the material in the first material gas into a material liquid and recover it to the container module 14. During this process, the first recovery module 12 may contain unrecovered third material gas, which is then input to the second recovery module 13 for further recovery.

[0058] Subsequently, after receiving the third material gas, the second recovery module 13 can perform multi-stage recovery of the third material gas. Specifically, the second recovery module 13 can condense the third material gas into a liquid state for recovery, and return the recovered liquid material to the container module 14. It can also transport the waste gas generated after multiple recovery processes of the third material gas to the waste gas treatment module 16 for waste gas treatment to prevent the waste gas from flowing into the environment and causing air pollution.

[0059] Meanwhile, the second recovery module 13 can also receive new gas and transport the new gas to the heating module 15 for heating, so that the new gas is mixed and heated with the recovered second material gas, and the heated mixed gas is transported to the material volatilization module 11 for utilization.

[0060] Furthermore, in order to increase the material recycling efficiency of the material recycling system, a material flow obstruction module can be set between the first pipe p1 and the second pipe p2 in the above-mentioned material recycling system. The material flow obstruction module can be used to filter the material in the second material gas into the first material gas, thereby increasing the concentration of the first material gas delivered to the first recycling module 12 through the first pipe p1. This allows the first recycling module 12 and the second recycling module 13 to recycle more material, thereby increasing the recycling efficiency of the material recycling system.

[0061] Furthermore, in order to prevent insufficient storage space in the container module 14, the container module 14 may include a first container sub-module and a second container sub-module.

[0062] Based on this, the first input terminal of the first container sub-module can be connected to the second output terminal O of the first recycling module 12. 22 The first output terminal O of the second recycling module 13 31 The top of the first container sub-module may be provided with a first drain outlet, and the first input end of the first container sub-module may be provided with a first shut-off valve.

[0063] The first input terminal of the second container sub-module can be connected to the second output terminal O of the first recycling module 12. 22 The first output terminal O of the second recycling module 13 31 The top of the second container sub-module may be provided with a second drain outlet, and the first input end of the second container sub-module may be provided with a second shut-off valve.

[0064] The material recovery system provided in this application embodiment utilizes a concentration-separated pipeline structure. The first and second pipelines respectively transport high-concentration and low-concentration material gases, allowing high-concentration gas to be directly connected to the first recovery module for priority recovery, while low-concentration gas is recycled and heated. This avoids dilution of recovery efficiency caused by mixing gases of different concentrations, achieving "precise diversion-targeted recovery" and laying a structural foundation for efficient recovery. Simultaneously, the series connection design of the first and second recovery modules forms a stepped recovery path of primary and multi-stage recovery, compensating for the incomplete processing of low-concentration gas by a single recovery module and significantly improving the integrity of material recovery. Furthermore, the system... The device module, through its dual-input structure directly connecting to the two major recovery modules, achieves centralized collection of recovered materials, avoiding losses and pollution caused by decentralized collection and simplifying subsequent processing. Furthermore, the closed-loop structure formed by the heating module, the material volatilization module, and the second recovery module allows low-concentration incoming gas to be recirculated and heated, reducing energy waste. Finally, the exhaust gas treatment module, as the end-point connection structure, precisely connects to the third output of the second recovery module, ensuring that unrecovered exhaust gas is treated before being discharged, structurally blocking pollution pathways. Ultimately, through the functional zoning and close connection of each module, efficient material recovery is achieved while avoiding environmental pollution.

[0065] See Figure 2 This is a schematic diagram of another material recycling system provided in an embodiment of this application. Figure 2 The structure shown is in Figure 1 An energy supply module 21 has been added to the structure shown. For example... Figure 2 As shown, the material recycling system 20 may include Figure 1 The structure of the material recycling system 10 and the energy supply module 21 are shown.

[0066] The energy supply module 21 is used to provide energy to the first recovery module 12 and the heating module 15 so that the corresponding modules can perform their respective functions. The energy supply module 21 can be a screw-type combined cooling and heating cascade unit, or other types of equipment capable of providing energy at different temperatures. This application embodiment does not limit this.

[0067] Optionally, the first recovery module 12 can be configured to perform heat exchange to condense the first material gas, thereby recovering the material from the first material gas.

[0068] Optionally, the heating module 15 can be configured to heat the received new gas and the second material gas, thereby delivering the heated mixed gas to the material volatilization module 11, so that the material volatilization module 11 can reuse the heated mixed gas.

[0069] Furthermore, the energy supply module 21 may include a first input terminal I.71 Second input terminal I 72 First output terminal O 71 and the second output terminal O 72 .

[0070] Furthermore, the aforementioned first recycling module 12 may also include: a second input terminal I 22 and the third output terminal O 23 .

[0071] Furthermore, the heating module 15 may also include: a second input terminal I 52 Second output terminal O 52 .

[0073] Through this connection, the energy supply module 21 can be used to provide energy (such as water or gas) to the first recovery module 12 for heat exchange with the first material gas, thereby condensing the first material gas to obtain a material liquid containing the material. For example, the energy supply module 21 can provide hot water at 70°C to the first recovery module 12, and then output hot water at 80°C from the first recovery module 21.

[0075] Through this connection, the energy supply module 21 can be used to provide a heat source to the heating module 15 to heat the incoming gas and the second material gas. For example, the energy supply module 21 can provide high-temperature hot water at 130°C to the heating module 15 and can receive high-temperature hot water at 120°C from the heating module 15.

[0076] Furthermore, in order to facilitate the control of the energy input to the first recovery module 12, thereby controlling the recovery efficiency of the first recovery module 12 for the first material gas, the first input terminal I of the aforementioned energy supply module 21... 71A first flow regulation module may be provided.

[0078] See another location. Figure 3 This is a schematic diagram of another material recycling system provided in the embodiments of this application. Figure 3 The process shown is in Figure 1 Based on the illustrated process, the specific structure of the second recycling module 13 is described. For example... Figure 3 As shown, the structure may include: Figure 1 The material recovery system 10 shown, and the second recovery module 13, include: a heat pipe heat recovery sub-module 131, an evaporation recovery sub-module 132, and a new gas heating sub-module 133.

[0079] The aforementioned heat pipe heat recovery sub-module 131 refers to a tubular component (or other types of heat recovery components, not limited to tubular components) capable of performing primary recovery of the received third material gas. Optionally, it can recover the materials contained in the third material gas through heat exchange and condensation.

[0083] Furthermore, the aforementioned evaporation recovery sub-module 132 may include: a first input terminal I 321 First output terminal O 321 Second output terminal O 322 .

[0084] Furthermore, the aforementioned new gas heating sub-module 133 may include: a first input terminal I 331 and the first output terminal O 332 .

[0085] Based on this, in the embodiments of this application, the heat pipe heat recovery sub-module 131, the evaporation recovery sub-module 132, and the incoming gas heating sub-module 133 may include the following connections: The first input terminal I of the aforementioned heat pipe heat recovery sub-module 131 311 The first output terminal O of the first recycling module 12 mentioned above is connected. 21 The second input terminal I of the aforementioned heat pipe heat recovery sub-module 131 312 Used to receive incoming gas; the first output terminal O of the aforementioned heat pipe heat recovery sub-module 131 311 Connect the second input terminal I of container module 14 42 .

[0086] The aforementioned heat pipe heat recovery sub-module 131 is used to heat the received new gas using the third material gas input from the first recovery module 12, and to input the recovered material liquid into the container module 14. Through this connection method, the heat pipe heat recovery sub-module 131 can simultaneously condense and recover materials from the third material gas while also pre-heating the new gas, for example, heating the new gas from 25°C to 50°C, thereby achieving efficient utilization of the energy in the third material gas. Based on this, the recovered material liquid can be transported into the container module 14.

[0087] The second output terminal O of the aforementioned heat pipe heat recovery sub-module 131 312 The first input terminal I connected to the above-mentioned evaporation recovery sub-module 132 321 The third output terminal O of the aforementioned heat pipe heat recovery sub-module 131 313 The first input terminal I of the newly introduced gas heating sub-module 133 is connected to the above-mentioned new gas heating sub-module. 331 .

[0088] Specifically, the heat pipe heat recovery submodule 131 can perform primary recovery of the third material gas while simultaneously heating the incoming gas. However, since the heat pipe heat recovery submodule 131 does not completely recover the third material gas, some material gas still needs further recovery. Therefore, through the above connection method, the heat pipe heat recovery submodule 131 can transport the primary recovered third material gas to the evaporation recovery submodule 132 for further recovery, and transport the pre-heated incoming gas to the incoming gas heating submodule for further heating.

[0089] The first output terminal O of the aforementioned evaporation recovery sub-module 132 321 The second input terminal I of the above container module 14 is connected 42 The second output terminal O of the aforementioned evaporation recovery sub-module 132 322 The first input terminal I connected to the above-mentioned exhaust gas treatment module 16 61 The first output terminal O of the aforementioned evaporation recovery sub-module 132 321 Used to feed the recycled material liquid into the container module 14.

[0090] Through the above connection method, the evaporation recovery sub-module 132 can recycle the third material gas input from the heat pipe heat recovery sub-module 131, transport the recovered material liquid to the container module 14 for storage, and transport the remaining waste gas to the waste gas treatment module 16 for treatment to prevent air pollution.

[0091] The first output terminal O of the aforementioned new gas heating sub-module 133 331 The first input terminal I of the heating module 15 is connected to the above-mentioned heating module 15. 51 .

[0092] Through this connection, the new gas heating sub-module 133 can reheat the new gas after receiving it from the heat pipe heat recovery sub-module 131, and then transport the heated new gas to the heating module 15 to mix and heat it with the second material gas.

[0093] For example, the incoming gas heating sub-module 133 can heat the incoming gas from 50°C to 70°C.

[0094] Furthermore, in order to accurately control the heat recovery efficiency of the heat pipe heat recovery sub-module 131, the first input terminal I of the aforementioned heat pipe heat recovery sub-module 131... 311 A first flow rate regulating unit is provided, and the second input terminal I of the aforementioned heat pipe heat recovery submodule 131 is... 312 A second flow regulation unit is provided.

[0095] The first flow regulating unit can be used to regulate the flow rate of the third material gas flowing into the heat pipe heat recovery sub-module 131, and the second flow regulating unit can be used to regulate the flow rate of the new gas flowing into the heat pipe heat recovery sub-module 131. Optionally, the first flow regulating unit and the second flow regulating unit can be the same type of flow regulating unit, such as proportional regulating dampers, or they can be different types of flow regulating units. This application embodiment does not limit this.

[0096] Furthermore, the aforementioned evaporation recovery submodule may include an evaporation unit and a first exhaust gas unit, and the aforementioned new gas heating submodule may include a power unit, a condensation unit, and a second exhaust gas unit. The aforementioned evaporation unit refers to a unit used for the re-recovery of the third material gas, and may be an evaporator. The aforementioned first exhaust gas unit refers to equipment used for discharging the obtained waste gas to the waste gas treatment module 16, such as a blower. The aforementioned power unit refers to a power device used for supplying refrigerant to the condensation unit and the evaporation unit to realize the condensation function of the evaporation unit and the heating function of the condensation unit, such as a compressor. The aforementioned condensation unit refers to a unit used for heating the received new gas. The aforementioned second exhaust gas unit refers to equipment used for conveying the heated new gas to the heating module 15, such as a blower.

[0097] Based on the above-mentioned components, the following connection methods are possible: The first input terminal of the aforementioned evaporation unit can serve as the first input terminal I of the evaporation recovery sub-module 132. 321 The first output terminal of the aforementioned evaporation unit is connected to the first input terminal of the aforementioned first exhaust gas unit, and the second output terminal of the aforementioned evaporation unit can serve as the first output terminal O of the evaporation recovery sub-module 132. 321 The first output terminal of the aforementioned first exhaust gas unit can be used as the second output terminal O of the evaporation recovery sub-module 132. 322 .

[0098] Through this connection, the evaporation unit can condense and recover the received third material gas, then transport the condensed material liquid to the container module 14 for storage, and transport the generated waste gas to the first exhaust gas unit, so that the waste gas can be transported to the waste gas treatment module 16 through the first exhaust gas unit.

[0099] The first input terminal of the aforementioned power unit can serve as the first input terminal I of the new gas heating sub-module 133. 331 The first output terminal of the aforementioned power unit is connected to the first input terminal of the aforementioned condensation unit; the first output terminal of the aforementioned condensation unit is connected to the first input terminal of the aforementioned second exhaust gas unit, and the first output terminal of the aforementioned second exhaust gas unit can serve as the first output terminal O of the new gas heating sub-module 133. 331 .

[0100] Through this connection, the condensation unit can reheat the received new gas and send the heated new gas to the second exhaust gas unit, so that the reheated new gas can be sent to the heating module 15 through the second exhaust gas unit.

[0101] In one embodiment, the power unit, condensing unit, and evaporating unit described above can constitute a refrigerant circulation system. In this refrigerant circulation system, the output terminal of the power unit can be connected to the input terminal of the condensing unit, the output terminal of the condensing unit can be connected to the input terminal of the evaporating unit, and the output terminal of the evaporating unit can be connected to the input terminal of the power unit.

[0102] Based on this connection method, the power unit can be a compressor, which can compress the refrigerant into a high-temperature, high-pressure gas and deliver the high-temperature, high-pressure gas to the condensing unit for condensation.

[0103] Subsequently, upon receiving the high-temperature, high-pressure gas, the condensation unit condenses it to obtain a low-temperature, low-pressure liquid or a low-temperature, low-pressure gas-liquid mixture. This process releases a significant amount of heat to heat the incoming gas.

[0104] Next, the condensation unit can transport the low-temperature, low-pressure liquid to the evaporation unit, which can evaporate the aforementioned low-temperature, low-pressure liquid or low-temperature, low-pressure gas-liquid mixture to obtain a low-temperature, low-pressure gas. During this process, the evaporation unit can absorb heat, thereby condensing the third material gas into a material liquid, achieving the recycling of the material.

[0105] The material recovery system provided in this application embodiment, by setting up a heat pipe heat recovery sub-module for primary recovery of the third material gas and simultaneous heating of the received new gas, an evaporation recovery sub-module for secondary recovery of the third material gas, and a new gas heating sub-module for reheating the new gas in the second recovery module, can simultaneously realize secondary recovery of the third material gas and secondary heating of the new gas, thereby achieving efficient recovery of the third material gas and efficient heating of the new gas.

[0106] To facilitate understanding of the material recycling system provided in this application, the following will be... Figure 1 , Figure 2 as well as Figure 3 The components of the corresponding system are combined, and an example of an actual component is used for illustration.

[0107] See Figure 4 This is a schematic diagram of another material recycling system provided in an embodiment of this application. Figure 4As shown, this structure is illustrated using the following examples: material evaporation module 11 is a coating machine baking platform; second recovery module 12 is a stainless steel finned heat exchanger; second recovery module 13 is a heat recovery evaporation-condensation unit; container module 14 consists of water storage tank 1 and water storage tank 2; heating module 15 is a high-temperature hot water heat exchanger; energy supply module 21 is a screw-type combined cooling and heating cascade unit; and waste gas treatment module is for waste gas treatment. Figure 4 As shown, the material recycling system may include: a coating machine baking platform, a stainless steel finned heat exchanger, a heat recovery evaporation and condensation unit, water storage tank 1 and water storage tank 2, a high-temperature hot water heat exchanger, a screw-type combined cooling and heating cascade unit, and a waste gas treatment module, etc.

[0108] The first output end of the coating machine baking platform can be connected to the input end of the stainless steel finned heat exchanger via a first pipe, and to the first input end of the high-temperature hot water heat exchanger via a second pipe; the first output end of the stainless steel finned heat exchanger can be connected to the first input end of the heat recovery evaporation and condensation unit, and the second output end can be connected to water storage tank 1 and water storage tank 2 respectively; the first output end of the heat recovery evaporation and condensation unit can be connected to the aforementioned water storage tank 1 and water storage tank 2 respectively, the second output end can be connected to the first input end of the high-temperature hot water heat exchanger, and the third output end can be connected to the waste gas treatment module for waste gas treatment; the first output end of the aforementioned high-temperature hot water heat exchanger can be connected to the first input end of the coating machine baking platform.

[0109] Furthermore, a flow-blocking plate (i.e., a material flow-blocking module) may be provided between the first and second pipes.

[0110] Furthermore, the system also includes a screw-type combined cooling and heating cascade unit. The first output end of the screw-type combined cooling and heating cascade unit can be connected to the second input end of a stainless steel finned heat exchanger. The first input end can be connected to the third output end of the stainless steel finned heat exchanger. The second output end can be connected to the second input end of a high-temperature hot water heat exchanger. The second input end can be connected to the second output end of the high-temperature hot water heat exchanger.

[0111] Furthermore, the first input end of the screw-type combined cooling and heating cascade unit may be equipped with a flow regulating valve 1.

[0112] Furthermore, water storage tank 1 may be equipped with a shut-off valve 1 and a drain outlet 1, and water storage tank 2 may be equipped with a shut-off valve 2 and a drain outlet 2.

[0113] Further, see Figure 5 This is a partial structural schematic diagram of a heat recovery evaporator-condenser unit provided in an embodiment of this application. Figure 5 As shown, the heat recovery evaporation-condensation unit may include an exhaust side, a fresh air side, a heat pipe heat recovery section (i.e., a heat pipe heat recovery sub-module), an evaporation section (i.e., an evaporation recovery sub-module), and a condensation section (i.e., a fresh gas heating sub-module).

[0114] The exhaust side can serve as the first input terminal of the heat recovery evaporative condenser unit to receive the third material gas input from the stainless steel finned heat exchanger, while the fresh air side serves as the second input terminal of the heat recovery evaporative condenser unit to receive the incoming fresh gas.

[0115] Furthermore, the aforementioned evaporation section includes an evaporator and a blower, and the condensation section includes a compressor, a condenser, and a blower. The evaporator and condenser are connected via a throttling tube. Furthermore, the output end of the compressor is connected to the input end of the condenser, the output end of the condenser is connected to one end of the throttling tube, the other end of the throttling tube is connected to the input end of the evaporator, and the output end of the evaporator is connected to the input end of the compressor.

[0116] Furthermore, the first input end of the heat pipe in the heat pipe heat return section mentioned above may be equipped with a proportional regulating air valve 1 for inputting the third material gas, and the second input end for inputting the new gas may be equipped with a proportional regulating air valve 2.

[0117] Furthermore, the exhaust side may be equipped with a temperature sensor 1 for detecting the temperature value of the input third material gas.

[0118] Furthermore, the aforementioned condensation section may be equipped with a temperature sensing element 2 for detecting the temperature of the new gas supplied to the condensation section.

[0119] Based on the above Figure 4 and Figure 5 The system structure shown is such that when the system is running, the heat recovery evaporator-condenser unit and the screw-type combined cooling and heating cascade unit start up and run synchronously. After the operation is stable, the water-side heat exchange path is as follows: high-temperature water with a water temperature of T1 (set to 130℃) enters the high-temperature hot water heat exchanger, and the outlet water temperature of T2 (set to 120℃) flows back to the screw-type combined cooling and heating cascade unit. Another high-temperature water with a water temperature of T3 (set to 70℃) enters the stainless steel finned heat exchanger, and the outlet water temperature of T4 (set to 80℃) flows back to the screw-type combined cooling and heating cascade unit.

[0120] The air-side heat exchange path is as follows: Fresh air (temperature 25℃) is heated to 50℃ through heat pipe heat recovery with exhaust air, then heated to 70℃ through condenser, and then mixed with return air into high-temperature hot water heat exchanger. The high-temperature hot air, heated to 120℃, enters the coating machine baking platform. On the coating machine baking platform, air is blown from bottom to top to dry the internal fabric at high temperature. The exhaust air (temperature 110℃) is divided into two layers. The upper layer air is used as return air and mixed with fresh air for a second time, while the lower layer air is used as exhaust air and enters the stainless steel finned heat exchanger for the first heat recovery. After heat exchange, the exhaust air (temperature 78℃) enters the heat recovery evaporator-condenser unit and undergoes a second heat recovery with fresh air through heat pipe heat recovery heat exchanger. After heat exchange, the exhaust air (temperature 55℃) enters the evaporator for cooling and cooling down. Finally, after cooling down to 40℃, it is discharged to the outside for subsequent waste gas treatment.

[0121] When the coating machine drying platform is running, the paint concentration in the exhaust air is relatively high. In order to reduce the paint concentration in the return air, a baffle plate is usually installed at the air inlet of the return air duct. When the filter material passes through the baffle plate, due to the high density of the filter material, it will get stuck in the groove of the baffle plate and flow back to the exhaust air, and then enter the next stage with the exhaust air.

[0122] During system operation, the stainless steel finned heat exchanger serves as the first heat recovery process, the heat pipes in the heat recovery evaporator-condenser unit serve as the second heat recovery process, and the evaporator and condenser serve as the third heat recovery process. Through step-by-step heat exchange, the exhaust heat of the coating machine drying platform is recovered to save the overall system's operating energy consumption.

[0123] Simultaneously, during the operation of the entire system, the hot air from the coating machine during drying will heat and remove the coating from the fabric. The coating will gradually cool during subsequent heat recovery steps and be discharged with the condensate. At this time, the water from the drip trays of the stainless steel finned heat exchanger, heat pipe heat recovery heat exchanger, and evaporator is simultaneously introduced into the water storage tank 1 (the water storage tank 2 is closed via shut-off valve 2). After gradual cooling, the coating dissolved in the water will gradually precipitate and accumulate in the water storage tank 1. Once the drain outlet of the water storage tank 1 is blocked, shut-off valve 1 is closed and shut-off valve 2 is opened, allowing collection using the water storage tank 2. Thus, the coating in the water storage tank 1 can be recovered, improving raw material utilization and reducing costs.

[0124] The material recycling system provided in this application has the following beneficial effects: Improved thermal energy utilization: Through a multi-stage heat recovery system (heat pipe heat recovery, condenser heating, evaporative cooling), a cascade heat exchange of fresh air, exhaust air, and return air is achieved, reducing energy loss and lowering operating costs; Simultaneous coating recovery: The condensate from the stainless steel finned heat exchanger, heat pipe heat recovery heat exchanger, and evaporator is introduced into a water storage tank, and the temperature gradient is used to cause the coating to precipitate, achieving efficient raw material recovery and reducing waste; Optimized condensate treatment: The gradient cooling design reduces the viscosity of the condensate, reducing the risk of pipe blockage. At the same time, the sedimentation collection simplifies the coating recycling process and improves system stability; Precise temperature control: The high-temperature hot water heat exchanger and the stainless steel finned heat exchanger are set with different water temperature paths to avoid heat cross-contamination and ensure precise control of hot air temperature (120℃→110℃→78℃→55℃), improving drying efficiency; Balancing environmental protection and economy: Reduces coating emissions in exhaust gas, lowers subsequent treatment costs, and enhances system compatibility through modular heat exchange integration design to meet the needs of large-scale industrial applications.

[0125] See Figure 6 This is a flowchart illustrating an embodiment of a control method for a material recycling system provided in this application. As one embodiment, Figure 6 The process shown can be used to control Figures 1 to 5Any material recycling system. For example... Figure 6 As shown, the method may include: Step 601: During the material recovery process of the material gas in the material volatilization module, the temperature value of the third material gas input from the first recovery module to the second recovery module is collected.

[0126] In this step, in order to ensure the overall recovery efficiency of the material recovery system for the material gas, the executing entity of this application embodiment can collect the temperature value of the third material gas when it is input into the second recovery module after the first recovery module completes the preliminary recovery of the first material gas to obtain the third material gas in real time or at regular intervals.

[0127] In one embodiment, based on Figures 1 to 5 In order to obtain the temperature value of the third material gas, the material recovery system shown may have a first temperature detection unit (e.g., ...) at the first input terminal of the second recovery module within the system. Figure 5 (See temperature sensing unit 1). Based on this, the executing entity of this application embodiment can collect the temperature value of the third material gas when it is input into the second recovery module through the first temperature detection unit.

[0128] Step 602: If the temperature value is not within the preset range, adjust the recycling efficiency of the first recycling module to bring the temperature value within the preset range.

[0129] The aforementioned preset range refers to a pre-set temperature range used to ensure high material recycling efficiency. Optionally, the preset range can be [70℃, 78℃], or a larger temperature range including this range, or a smaller temperature range within this range. This application embodiment does not impose any limitations on this.

[0130] In this step, it can be determined whether the temperature value of the third material gas is within the preset range when it is input into the second recovery module.

[0131] Optionally, when the temperature value is determined to be within the preset range, it can be determined that the second recovery module can operate normally and efficiently. At this time, the material recovery efficiency of the system is high, so the material recovery system can be controlled to continue operating according to the current operating strategy.

[0132] Optionally, if it is determined that the temperature value is not within the preset range, it can be determined that the second recycling module cannot operate efficiently. At this time, the material recycling efficiency of the system is low. Therefore, the recycling efficiency of the first recycling module can be adjusted so that the temperature value is within the preset range, thereby ensuring the efficient operation of the second recycling module and improving the recycling efficiency of the material recycling system.

[0133] In one embodiment, by Figure 2As shown in the system structure, the material recycling system also includes an energy supply module, which provides energy to the first recycling module. This first energy supply module may include a first flow regulation module (e.g., Figure 4 The flow regulating valve 1 shown is used to regulate the energy flow from the first recovery module into the energy supply module.

[0134] Based on this, the energy supply flow from the energy supply module to the first recovery module can be adjusted by regulating the opening degree of the first flow regulation module, thereby adjusting the recovery efficiency of the first recovery module.

[0135] As an optional implementation, the temperature value can be compared with the maximum and minimum values ​​of a preset range to determine whether the temperature value exceeds or falls below the preset range.

[0136] Optionally, if the temperature value is determined to be greater than the maximum value of the preset range, the opening of the first flow regulating module can be increased to improve the heat exchange capacity of the first recovery module, thereby improving the recovery efficiency of the first recovery module and reducing the temperature value when the third material gas enters the second recovery module.

[0137] Optionally, if the temperature value is determined to be less than the minimum value of the preset range, the opening of the first flow regulating module can be reduced to decrease the heat exchange capacity of the first recovery module, thereby reducing the recovery efficiency of the first recovery module and increasing the temperature value when the third material gas enters the second recovery module.

[0138] Furthermore, in one embodiment, by Figure 3 As shown in the material recovery system structure, the second recovery module may include: a heat pipe heat recovery submodule, an evaporation recovery submodule, and a new gas heating submodule. The heat pipe heat recovery submodule may be equipped with a first flow regulation unit, which can be used to regulate the flow rate of the third material gas flowing into the heat pipe heat recovery submodule, for example... Figure 5 The proportional regulating air valve 1 is shown.

[0139] Based on this, after controlling the opening of the first flow regulation module to reduce the heat exchange capacity of the first recovery module, the temperature value of the third material gas when it enters the second recovery module can be collected, and it can be determined whether the temperature value is within the preset range.

[0140] Optionally, if the temperature value is determined to be less than a preset range, the opening of the first flow regulating unit can be increased to increase the flow rate of the third material gas flowing into the heat pipe heat recovery sub-module, thereby increasing the temperature value of the third material gas when it enters the second recovery module.

[0141] Furthermore, through Figure 3 As shown in the process diagram, the heat pipe heat recovery sub-module is also equipped with a second flow regulation unit, which is used to regulate the flow rate of the new gas flowing into the heat pipe heat recovery sub-module.

[0142] Based on this, in order to increase the system's operating efficiency, the execution entity of this application embodiment can collect the temperature of the incoming gas flowing into the incoming gas heating sub-module in real time, and determine whether the temperature of the incoming gas is greater than a preset temperature threshold. The aforementioned temperature threshold is a preset maximum temperature value of the incoming gas flowing into the incoming gas heating sub-module, for example, 50°C.

[0143] As one embodiment, a second temperature detection unit can be provided at the input end of the new gas heating sub-module, for example... Figure 5 The temperature sensing element 2 is shown. Based on this, the execution subject of this application embodiment can collect the temperature of the incoming gas flowing into the incoming gas heating sub-module through the second temperature detection unit.

[0144] Optionally, if the temperature of the incoming gas is determined to be greater than a preset temperature threshold, the opening of the second flow regulating unit can be increased to reduce the temperature of the incoming gas flowing into the incoming gas heating sub-module.

[0145] The technical solution provided in this application involves collecting the temperature value of the third material gas input from the first recovery module to the second recovery module during the material recovery process of the material gas in the material volatilization module. If the temperature value is not within a preset range, the recovery efficiency of the first recovery module is adjusted to bring the temperature within the preset range. This technical solution uses the temperature value of the third material gas as a key feedback indicator of the recovery effect. By monitoring whether the temperature is within the preset range in real time, the recovery efficiency of the first recovery module is precisely controlled. This avoids problems such as incomplete material recovery and insufficient purity of the recovered liquid caused by temperature deviations, and also prevents abnormal temperatures from interfering with the multi-stage recovery effect of the subsequent second recovery module, ensuring that the entire recovery process always operates under optimal temperature conditions. Simultaneously, this dynamic adjustment mechanism requires no manual intervention and can adapt to fluctuations in variables such as material gas concentration and flow rate, improving the stability and automation of the system operation. Therefore, it can improve the system's material recovery efficiency while ensuring the quality of material recovery.

[0146] See Figure 7 This is a flowchart illustrating an embodiment of a control method for a material recycling system provided in this application. Figure 7 The process shown is in Figure 6Based on the illustrated process, this paper describes how the system further includes container modules for storing recycled material liquids. Each container module comprises a first container sub-module and a second container sub-module. The first container sub-module has a first drain outlet at its top and a first shut-off valve at its first input terminal. The second container sub-module has a second drain outlet at its top and a second shut-off valve at its first input terminal. The paper details how the system controls the recycling of material liquids when the first shut-off valve of the first container sub-module is open and the second shut-off valve of the second container sub-module is closed. Figure 7 As shown, the process may include the following steps: Step 701: Obtain the drain status of the first drain outlet of the first container sub-module.

[0147] Step 702: If the above-mentioned drain outlet status indicates that the first drain outlet is blocked, close the first shut-off valve and open the second shut-off valve.

[0148] The following provides a unified explanation of steps 701 and 702: The above-mentioned drain outlet status refers to the first container sub-module (e.g., Figure 4 The state of the first drain outlet of the water storage tank 1 shown may include a flowing state and a blocked state.

[0149] In this step, when the container module includes a first container module and a second container module, and the two container sub-modules are connected in parallel, in order to improve the utilization rate of the container sub-modules, the material recycling system provided in this application embodiment can first recycle the recycled material liquid through the first container sub-module. After the storage space in the first container sub-module is used up, the recycled material liquid is then recycled through the second container module. Therefore, the opening states of the shut-off valves of the first and second container sub-modules in this material recycling system are as follows: the first shut-off valve of the first container sub-module is open, and the second shut-off valve of the second container module is closed. Specifically, when the corresponding shut-off valve is closed, the material liquid does not flow into the corresponding container sub-module; that is, when the first shut-off valve is open and the second shut-off valve is closed, the recycled material liquid flows into the first container sub-module but not into the second container module.

[0150] Based on this, in order to enable the second container sub-module to be opened in a timely manner for material liquid recovery when the first container sub-module has no storage space, the execution subject of this application embodiment can detect and obtain the drain status of the first drain outlet of the first container sub-module in real time.

[0151] As an optional implementation, both the first and second container sub-modules have float valves to determine whether the internal fluid has reached the top. When the fluid reaches the drain outlet, the float rises to the top, indicating that the drain outlet is blocked. Therefore, the drain outlet status of the first drain outlet can be determined by the height of the float valve.

[0152] As one implementation, the height value of the float valve can be obtained. When the height value is greater than a preset height threshold, it indicates that the drain outlet of the first drain outlet is blocked; when the height value is less than or equal to the height threshold, it indicates that the drain outlet of the first drain outlet is not blocked.

[0153] Optionally, if the above-mentioned drain outlet status indicates that the first drain outlet is blocked, the first shut-off valve can be controlled to close and the second shut-off valve can be controlled to open, so that the second container sub-module can receive the material liquid recovered by the first container sub-module.

[0154] The technical solution provided in this application obtains the drain status of the first drain outlet of the first container sub-module. When the drain status indicates that the first drain outlet is blocked, the first shut-off valve is closed and the second shut-off valve is opened. This technical solution, by accurately capturing the blockage status of the first drain outlet and triggering valve switching, can quickly avoid problems such as the accumulation of recycled liquid and abnormal pressure within the container module caused by blockage, preventing the accumulated liquid from damaging the first recycling module or affecting the material recycling efficiency. At the same time, closing the first shut-off valve can block further fault transmission through the blocked channel, and opening the second shut-off valve can activate the backup drainage path, ensuring the continuous discharge of recycled liquid and the normal operation of the container module. Fault self-adaptation can be achieved without manual emergency handling. This automated emergency switching mechanism not only improves the stability and fault tolerance of the system operation, but also reduces manual maintenance costs, ensuring that the entire material recycling process is not affected by the blockage of a single drain outlet and maintains efficient and continuous operation.

[0155] To facilitate understanding of the control method of the material recycling system provided in this application, the following will use the control method as an example. Figure 4 Taking the material recycling system shown as an example, the control method of the material recycling system is illustrated: See Figure 8 This is a flowchart illustrating an embodiment of a control method for a material recycling system provided in this application. Figure 8 As shown, the process may include the following: exist Figure 4During the operation of the material recovery system, when the heat recovery evaporator-condenser unit is running, in order to control the temperature of the exhaust air entering the heat recovery evaporator-condenser unit and protect the refrigerant inside the heat pipe heat recovery heat exchanger, when the temperature sensor 1 on the exhaust side detects a temperature higher than 78℃, the opening of the flow regulating valve 1 at the heat recovery water inlet of the screw-type combined cooling and heating cascade unit is increased to improve the heat exchange capacity of the stainless steel finned heat exchanger, thereby reducing the exhaust air temperature entering the heat pipe. When the temperature sensor on the exhaust side detects a temperature lower than 70℃, in order to improve the heat exchange efficiency of the heat pipe, the opening of the flow regulating valve 1 is reduced, thereby increasing the exhaust air temperature entering the heat pipe. If the temperature increase does not reach the upper limit, the opening of the proportional regulating valve 1 is increased simultaneously to further increase the exhaust air temperature entering the heat pipe. In addition, when the unit is heating in the condensing section, in order to ensure the heating effect of the condenser, the temperature entering the condensing section generally needs to be controlled to not exceed 50℃. When the temperature sensor 2 detects a temperature exceeding 50℃, the opening of the proportional regulating valve 2 is increased to reduce the temperature entering the condensing section.

[0156] Meanwhile, during the operation of the entire system, the hot air from the coating machine during drying will simultaneously heat and remove the coating from the fabric. The coating will gradually cool down in subsequent heat recovery steps and be discharged with the condensate. At this time, the water from the drip trays of the stainless steel finned heat exchanger, heat pipe heat recovery heat exchanger, and evaporator will be simultaneously introduced into the water storage tank 1 (the water storage tank 2 is closed via shut-off valve 2). After gradual cooling, the coating dissolved in the water will gradually precipitate and accumulate in the water storage tank 1. Once the drain outlet of the water storage tank 1 is blocked, shut-off valve 1 is closed and shut-off valve 2 is opened, allowing the water storage tank 2 to collect the coating. Thus, the coating can be recovered from the water storage tank 1, improving raw material utilization and reducing costs.

[0157] The technical solution provided in this application has the following beneficial effects: Improved thermal energy utilization: Through a multi-stage heat recovery system (heat pipe heat recovery, condenser heating, evaporative cooling), a cascade heat exchange of fresh air, exhaust air, and return air is achieved, reducing energy loss and lowering operating costs; Simultaneous coating recovery: Condensate from the stainless steel finned heat exchanger, heat pipe heat recovery heat exchanger, and evaporator is introduced into a storage tank, and the temperature gradient is used to cause the coating to precipitate, achieving efficient raw material recovery and reducing waste; Optimized condensate treatment: The gradient cooling design reduces the viscosity of the condensate, reducing the risk of pipe blockage. At the same time, the sedimentation collection simplifies the coating recovery process and improves system stability; Precise temperature control: The high-temperature hot water heat exchanger and the stainless steel finned heat exchanger are set with different water temperature paths to avoid heat cross-contamination and ensure precise control of hot air temperature (120℃→110℃→78℃→55℃), improving drying efficiency; Balancing environmental protection and economy: Reduces coating emissions in exhaust gas, lowers subsequent treatment costs, and enhances system compatibility through modular heat exchange integration design to meet the needs of large-scale industrial applications.
