Abstract
Description
Technical Field
[0001] This utility model relates to the field of gelatin processing and drying technology, and more specifically, to a processing system. Background Technology
[0002] Gelatin is a collagen protein extracted from animal connective tissue or bone, widely used in food, cosmetics, pharmaceuticals, photography, and industry. The gelatin drying process is a crucial step in gelatin production. Gelatin solution with a water content of 70% is gradually dried to approximately 8% water content using a long-net drying line, transforming it into dry gelatin for storage, transportation, and subsequent applications. The long-net drying line is divided into multiple drying sections, equipped with a circulating air heating system, with the drying temperature gradually increasing. Fresh air is supplied to the drying line to remove high-temperature, high-humidity exhaust air, achieving dehumidification of the production line. Generally, a rotary dehumidifier is used to treat the fresh air to a low-humidity state before sending it into the drying line. Simultaneously, multiple heaters are installed on the drying line to output high-temperature air to dry the gelatin.
[0003] However, the dehydration and regeneration process of a rotary dehumidifier requires a large amount of heat energy; at the same time, the heater outputting high-temperature air also requires a large amount of heat energy, which usually comes from steam generated by a gas boiler. The high energy consumption during operation leads to high natural gas costs. Utility Model Content

[0023] Please refer to Figure 1 This utility model provides a processing system, including: a solution dehumidifier 41, which contains a dehumidifying solution that exchanges heat with fresh air to cool and dehumidify the fresh air passing through it, forming low-humidity fresh air; a heating component, which is connected to the solution dehumidifier 41 to heat the low-humidity fresh air flowing out of the solution dehumidifier 41; a drying unit 4, which has a ventilation area and a heating channel, wherein the ventilation area is provided with a component to be dried, and the ventilation area of the drying unit 4 is connected to the heating component so that the low-humidity fresh air flowing out of the heating component passes through the ventilation area of the drying unit 4 to form exhaust air; and a solution regeneration component 51, which contains... The solution regeneration component 51 is used to contain the regeneration solution. The solution regeneration component 51 is connected to the ventilation area of the drying unit 4 and the solution dehumidification component 41, so that a portion of the regeneration solution and the exhaust air flowing out of the drying unit 4 come into contact and exchange heat before being introduced into the solution dehumidification component 41. The solution heat exchange component 61 is used to contain the heat exchange liquid inside. The solution heat exchange component 61 is connected to the solution regeneration component 51, so that the heat exchange liquid and the exhaust air flowing out of the solution regeneration component 51 exchange heat before exchanging heat with the liquid to be heated 2 to form the heating liquid 1. The heating liquid 1 is used to be introduced into the heating channel to heat and dry the workpiece to be dried.
[0024] The processing system of this utility model includes a solution dehumidification component 41, a heating component, a solution regeneration component 51, a drying unit 4, and a solution heat exchanger 61. When fresh air with high humidity flows through the solution dehumidification component 41, it comes into contact with the dehumidification solution for heat exchange, thus cooling and dehumidifying the fresh air. At the same time, the dehumidification solution in the solution dehumidification component 41 is diluted. Then, the fresh air flowing out of the solution dehumidification component 41 flows through the heating component for heating. The heated fresh air flowing out of the heating component flows into the ventilation area of the drying unit 4 to form high-temperature exhaust air. Then, the high-temperature exhaust air flowing out of the drying unit 4 flows through the solution regeneration component 51 for heat exchange with the regeneration solution, thus cooling and dehumidifying the fresh air. The regeneration solution is concentrated, and a portion of the concentrated regeneration solution in the solution regeneration unit 51 enters the solution dehumidification unit 41 to maintain the concentration of the dehumidification solution and achieve continuous cooling and dehumidification of the fresh air. Then, the high-temperature exhaust air flowing out of the solution regeneration unit 51 flows into the solution heat exchanger 61 and exchanges heat with the heat exchange liquid inside the solution heat exchanger 61. The heat exchange liquid then exchanges heat with the liquid to be heated 2 outside the solution heat exchanger 61, so that the heat of the high-temperature exhaust air is transferred to the liquid to be heated 2 through the heat exchange liquid, so that the liquid to be heated 2 is heated to form the heating liquid 1. The heating liquid 1 is used to enter the heating channel of the heater so that the heater outputs high-temperature air to heat and dry the items to be dried. Therefore, the processing system of this utility model can make full use of the heat in the high-temperature exhaust air flowing out of the drying unit 4. On the one hand, the high-temperature exhaust air can be used to concentrate the regenerated solution in the solution regeneration component 51, and the concentration of the dehumidifying solution in the solution dehumidifying component 41 can be maintained through interstage flow solution exchange, thereby achieving cooling and dehumidification of the fresh air. The rotary dehumidifier is no longer needed, which greatly saves the energy required to cool and dehumidify the fresh air. On the other hand, the heat in the high-temperature exhaust air can be recovered by the solution heat exchange component 61, so that the liquid to be heated 2 is heated to form the heating liquid 1. The heating liquid 1 can be used as the heat energy source of the heater, so that the heat energy source of the heater does not depend on the boiler hot water, which greatly saves the energy required to dry the parts to be dried. Thus, the processing system of this utility model has low operating energy consumption, significantly reduces the operating cost of the processing system, and improves the economy of the processing system.
[0025] Specifically, in the prior art, the heating channel inside the heater is circulated with boiler hot water, and the heat exchange channel inside the heater is circulated with ambient air. The boiler hot water and ambient air exchange heat in the heater, so that the ambient air is heated to form high-temperature air, which then heats and dries the workpiece.
[0026] The heating channel of the drying unit 4 in this application is arranged inside the heater. The heating liquid 1 is used to enter the heating channel of the heater to exchange heat with the room temperature air inside the heater. The room temperature air is heated to form high temperature air and then introduced into the ventilation area of the drying unit 4 to heat and dry the workpiece.
[0027] Specifically, such as Figure 1 As shown, multiple drying sections for gelatin are arranged in an orderly manner within the ventilation area of the drying unit 4. There are multiple heaters. The high-temperature air temperature required for the preceding drying section is lower than that required for the following drying section. The heat energy source for the heaters corresponding to the preceding drying section comes from the heating liquid 1. When the heat provided by the heating liquid 1 is insufficient, the heat energy source for the heaters corresponding to the following drying section is supplemented by the heat from the boiler hot water. The boiler hot water supply 7 flows into the heating channel of the heater, exchanges heat with the ambient temperature air, and then flows out of the boiler hot water return 8.
[0028] Optionally, the dehumidifying solution in the solution dehumidifier 41 is a calcium chloride solution, a lithium chloride solution, or a lithium bromide solution.
[0029] In this embodiment, the solution regeneration unit 51 includes a first spraying section 534 for spraying regeneration solution; the processing system further includes a first reflux medium pipeline 512 and a second reflux medium pipeline 513, the inflow end and the outflow end of the first reflux medium pipeline 512 are respectively connected to the solution regeneration unit 51 and the solution dehumidification unit 41, and the inflow end and the outflow end of the second reflux medium pipeline 513 are respectively connected to the solution dehumidification unit 41 and the solution regeneration unit 51; a first heat exchanger 53, through which both the first reflux medium pipeline 512 and the second reflux medium pipeline 513 flow, so that the dehumidification solution flowing out of the solution dehumidification unit 41 and the regeneration solution flowing out of the solution regeneration unit 51 exchange heat in the first heat exchanger 53.
[0030] Specifically, by spraying the regeneration solution through the first spray section 534, it is ensured that the regeneration solution and the fresh air entering the solution regeneration unit 51 are in full contact for heat exchange, ensuring that the fresh air can be adequately cooled and dehumidified. The first return medium pipeline 512 and the second return medium pipeline 513 are used to connect the solution dehumidification unit 41 and the solution regeneration unit 51, ensuring that the partially diluted dehumidification solution in the solution dehumidification unit 41 can flow into the solution regeneration unit 51, and ensuring that the partially concentrated regeneration solution in the solution regeneration unit 51 can flow into the solution dehumidification unit 41. The solution is maintained through interstage flow solution exchange. The concentration of the dehumidifying solution in the liquid dehumidifier 41 is adjusted to achieve continuous heat exchange with the fresh air. The dehumidifying solution flowing out of the liquid dehumidifier 41 and the regenerating solution flowing out of the liquid regeneration unit 51 exchange heat in the first heat exchange unit 53. This allows the heat of the regenerating solution flowing out of the liquid regeneration unit 51 to be transferred to the dehumidifying solution flowing out of the liquid dehumidifier 41, reducing the heat required for the regenerating solution in the liquid regeneration unit 51 to be concentrated. This allows more heat from the high-temperature exhaust air to be transferred to the heat exchange liquid inside the liquid heat exchange unit 61, further maximizing the utilization of the heat from the high-temperature exhaust air.
[0031] In this embodiment, the processing system further includes: a first diversion medium pipeline 531, a first pump body 52, and a third return medium pipeline 532. The first pump body 52 is disposed on the first diversion medium pipeline 531. The outlet end of the second return medium pipeline 513 and the inlet end of the first diversion medium pipeline 531 are both connected to the bottom of the tank of the solution regeneration component 51. The outlet end of the first diversion medium pipeline 531 is connected to the inlet end of the first return medium pipeline 512 and the inlet end of the third return medium pipeline 532, respectively.

[0033] In this embodiment, the processing system further includes: a second diversion medium pipeline 421, a second pump body 42, and a fourth return medium pipeline 422. The second pump body 42 is disposed on the second diversion medium pipeline 421. The outlet end of the first return medium pipeline 512 and the inlet end of the second diversion medium pipeline 421 are connected to the bottom of the tank of the solution dehumidification component 41. The outlet end of the second diversion medium pipeline 421 is connected to the inlet end of the second return medium pipeline 513 and the inlet end of the fourth return medium pipeline 422, respectively. The outlet end of the fourth return medium pipeline 422 is connected to the second spraying part 432 of the solution dehumidification component 41. A second heat exchanger 43 is disposed on the fourth return medium pipeline 422. The dehumidification solution in the fourth return medium pipeline 422 flows through the second heat exchanger 43 to exchange heat with the low-temperature heat exchanger in the second heat exchanger 43.
[0034] Specifically, the second pump body 42 is used to pump the dehumidification solution out of the solution dehumidification component 41, providing the power for the flow of the dehumidification solution; the fourth return medium pipeline 422 is used to return most of the dehumidification solution in the second diversion medium pipeline 421 to the second spray section 432 of the solution dehumidification component 41, so as to continuously cool and dehumidify the fresh air.
[0035] Specifically, one heat exchange channel of the second heat exchanger 43 is used to introduce the low-temperature heat exchange medium 3 (chilled water), and the other heat exchange channel is used to allow the fourth return medium pipeline 422 to pass through, so that the dehumidification solution can exchange heat with the chilled water in the second heat exchanger 43, thereby enhancing the cooling and dehumidification effect on the fresh air.
[0036] In this embodiment, a first packed reactor 431 is provided inside the solution dehumidification component 41, an airflow inlet and a second solution collection section are provided at the bottom of the solution dehumidification component 41, a second spray section 432 and an airflow outlet are provided at the top of the solution dehumidification component 41, and the first packed reactor 431 is disposed between the airflow inlet and the second spray section 432.
[0037] Specifically, the first packed reactor 431 increases the contact time between fresh air and dehumidifying solution, ensuring that fresh air and dehumidifying solution have sufficient contact and heat exchange in the first packed reactor 431, ensuring that fresh air is sufficiently cooled and dehumidified, and avoiding high humidity in the fresh air flowing out of the solution dehumidification component 41.
[0038] In this embodiment, the heating assembly includes a first heating element 72, which has a heat exchange channel and an airflow channel. The heat exchange medium in the heat exchange channel is used to exchange heat with the low-humidity fresh air in the airflow channel of the first heating element 72 to heat the low-humidity fresh air. The processing system also includes a first cooling element 71, which has a heat exchange channel and an airflow channel. The two ends of the airflow channel are respectively connected to the air exchange area of the drying unit 4 and the airflow inlet of the solution regeneration element 51. The heat exchange medium in the heat exchange channel is used to exchange heat with the exhaust air in the airflow channel of the first cooling element 71. A first exchange medium pipeline 711 and a second exchange medium pipeline 712 are also included. The outlet end and inlet end of the first exchange medium pipeline 711 are respectively connected to the heat exchange channel of the first cooling element 71 and the heat exchange channel of the first heating element 72. The outlet end and inlet end of the second exchange medium pipeline 712 are respectively connected to the heat exchange channel of the first heating element 72 and the heat exchange channel of the first cooling element 71 to exchange the heat exchange medium in the first heating element 72 and the first cooling element 71.
[0039] Specifically, when the processing system is in ventilation mode, the high-temperature exhaust air flowing out from the air exchange area of the drying unit 4 enters the airflow channel of the first cooling component 71. The heat exchange medium in the heat exchange channel of the first cooling component 71 exchanges heat with the high-temperature exhaust air in the airflow channel of the first cooling component 71, so that the heat exchange medium in the first cooling component 71 is heated. Then, the heat exchange medium in the first cooling component 71 flows into the first heating component 72 through the second exchange medium pipeline 712, so that the heat exchange medium in the first heating component 72 can exchange heat with the low-humidity fresh air flowing through the first heating component 72 to heat the low-humidity fresh air. Then, the heat exchange medium in the first heating component 72 returns to the first cooling component 71 through the first exchange medium pipeline 711 to continue to recover the heat of the high-temperature exhaust air, further making full use of the heat of the high-temperature exhaust air, so as to realize the recycling of the heat exchange medium, which helps to reduce the operating energy consumption of the processing system of this utility model.
[0040] In this embodiment, the heating assembly includes: a second heating element 12, wherein the heat exchange medium in the heat exchange channel of the second heating element 12 is used to exchange heat with the low-humidity fresh air in the airflow channel of the second heating element 12 to heat the low-humidity fresh air; and a third heating element 22, used to heat the low-humidity fresh air; wherein the two ends of the airflow channel in the second heating element 12 are respectively connected to the airflow outlet of the solution dehumidification element 41 and the airflow channel of the third heating element 22, and the airflow channel of the third heating element 22 is also connected to the airflow channel of the first heating element 72.
[0041] Specifically, the low-humidity fresh air flowing out of the solution dehumidifier 41 flows sequentially through the second heating element 12 and the third heating element 22 for heating, and then flows into the ventilation area of the drying unit 4 via the first heating element 72 (at this time, the first heating element 72 does not heat the fresh air) to avoid the fresh air flowing into the ventilation area of the drying unit 4 having a low temperature.
[0042] In this embodiment, the processing system further includes a cooling assembly, which includes a second cooling element 11, a third cooling element 21, and a fourth cooling element 31. One end of the airflow channel of the second cooling element 11 is used to introduce fresh air, and the heat exchange medium in the heat exchange channel of the second cooling element 11 is used to exchange heat with the fresh air in the airflow channel of the second cooling element 11 to cool and dehumidify the fresh air. The third cooling element 21 is used to cool the dehumidified fresh air. The heat exchange medium in the heat exchange channel of the fourth cooling element 31 is used to exchange heat with the fresh air in the airflow channel of the fourth cooling element 31 to cool and dehumidify the fresh air. The two ends of the airflow channel of the third cooling element 21 are respectively connected to the airflow channels of the second cooling element 11 and the fourth cooling element 31, and the airflow channel of the fourth cooling element 31 is also connected to the airflow inlet of the solution dehumidification element 41.
[0043] Specifically, the fresh air flows sequentially through the second cooling element 11, the third cooling element 21, the fourth cooling element 31 and the solution dehumidification element 41, so that the second cooling element 11, the third cooling element 21 and the fourth cooling element 31 cool the fresh air in sequence, thereby reducing the temperature and humidity of the fresh air.
[0044] Optionally, the heat exchange medium in the heat exchange channel of the fourth cooling element 31 is a low-temperature heat exchange medium 3, namely chilled water at 14°C, which can improve the operating efficiency of the fourth cooling element 31.
[0045] In this embodiment, the processing system further includes a seventh return medium pipeline 231, an eighth return medium pipeline 241, a first expansion valve 23, and a first compressor 24. The inflow and outflow ends of the seventh return medium pipeline 231 are connected to the third cooling element 21 and the third heating element 22, respectively. The inflow and outflow ends of the eighth return medium pipeline 241 are connected to the third heating element 22 and the third cooling element 21, respectively. The first expansion valve 23 is disposed on the eighth return medium pipeline 241, and the first compressor 24 is disposed on the seventh return medium pipeline 231.
[0046] Specifically, the low-pressure heat exchange medium in the third cooling element 21 changes from a liquid to a gaseous state, absorbing heat from the fresh air flowing out of the second cooling element 11. Then, the heat exchange medium in the third cooling element 21 flows into the first compressor 24, which compresses the low-pressure heat exchange medium from the third cooling element 21 into a high-pressure heat exchange medium. This high-pressure heat exchange medium then flows into the third heating element 22, where it liquefies to heat the low-humidity fresh air flowing out of the second heating element 12. The high-pressure heat exchange medium flowing out of the third heating element 22 then flows into the first expansion valve 23, which depressurizes the high-pressure heat exchange medium, turning it into a low-pressure heat exchange medium that flows back into the third cooling element 21, thus achieving the recycling of the heat exchange medium. Simultaneously, the first expansion valve 23 controls the flow rate of the heat exchange medium, ensuring sufficient evaporation of the heat exchange medium in the third cooling element 21 while preventing excessive heat exchange medium from entering, which could lead to incomplete evaporation or "liquid slugging."
[0047] Specifically, the heat exchange medium in the third cooling element 21 and the heat exchange medium in the third heating element 22 can be interchanged to realize the recycling of the heat exchange medium, which helps to reduce the operating energy consumption of the processing system of this utility model.
[0048] Optionally, the first compressor 24 is a variable frequency compressor, and the final air supply temperature can be controlled by adjusting the frequency of the first compressor 24. The fresh air temperature entering the air exchange area of the drying unit 4 can generally reach 30-35℃, and the exhaust air temperature can reach 60℃. The heating liquid 1 flowing out from the solution heat exchange element 61 is high-temperature hot water above 60℃.
[0049] In this embodiment, the processing system further includes a third exchange medium pipeline 311 and a fourth exchange medium pipeline 312. The inlet and outlet ends of the third exchange medium pipeline 311 are respectively connected to the heat exchange channels of the second cooling element 11 and the second heating element 12. The inlet and outlet ends of the fourth exchange medium pipeline 312 are respectively connected to the heat exchange channels of the second heating element 12 and the second cooling element 11 to exchange the heat exchange medium in the second heating element 12 and the second cooling element 11.
[0050] Specifically, the third and fourth exchange medium pipelines 311 and 312 are used to exchange the heat exchange medium in the second heating element 12 and the second cooling element 11. This allows the heat exchange medium in the second cooling element 11 to absorb the heat from the fresh air and increase its temperature. Then, it flows into the second heating element 12 and exchanges heat with the fresh air flowing through it, transferring the heat to the fresh air. This fully utilizes the heat of the fresh air, further saving the energy required for cooling and dehumidifying the fresh air, and helps reduce the operating energy consumption of the processing system.
[0051] In this embodiment, a second packed reactor 101 is provided inside the solution heat exchanger 61. An airflow inlet and a second solution collection section 102 are provided at the bottom of the solution heat exchanger 61. A third spray section 103 and an airflow outlet are provided at the top of the solution heat exchanger 61. The third spray section 103 is used to spray the heat exchange liquid. The second packed reactor 101 is disposed between the airflow inlet and the third spray section 103 so that the exhaust air flowing in from the airflow inlet can contact the heat exchange liquid for heat exchange.
[0052] Specifically, the second packed reactor 101 increases the contact time between the exhaust air and the heat exchange liquid, ensuring that the exhaust air and the heat exchange liquid are in full contact and heat exchange within the heat exchange liquid, ensuring that the heat exchange liquid is fully heated, and avoiding the heat exchange liquid flowing out of the solution heat exchange element 61 being at a low temperature, or the heat of the exhaust air being not fully utilized.
[0053] In this embodiment, the processing system further includes a sixth diversion medium pipeline 104, a fifth pump body 106, and a third evaporator 63. The fifth pump body 106 is disposed on the sixth diversion medium pipeline 104. The inflow end and outflow end of the sixth diversion medium pipeline 104 are respectively connected to the second solution collection section 102 and the third spray section 103 of the solution heat exchanger 61. The third evaporator 63 is used to contain low-pressure heat exchange medium, so that the low-pressure heat exchange medium is vaporized to cool the heat exchange liquid flowing into the third spray section 103.
[0054] Specifically, the sixth diversion medium pipeline 104 connects the second solution collection section 102 and the third spray section 103 of the solution heat exchanger 61, ensuring that the heat exchange liquid can circulate between the second solution collection section 102 and the third spray section 103. The second solution collection section 102 collects the heat exchange liquid whose temperature has increased after heat exchange with the exhaust air in the solution heat exchanger 61; the third spray section 103 sprays the cooled heat exchange liquid into the solution heat exchanger 61, allowing it to further contact the exhaust air and achieve heat exchange. The fifth pump body 106 provides power for the circulation of the heat exchange liquid, ensuring that the heat exchange liquid can circulate in the solution heat exchanger 61 at an appropriate speed, thereby improving the heat exchange efficiency of the solution heat exchanger 61. The third evaporator 63 is used to circulate and absorb heat from the heat exchange liquid, cooling the circulating heat exchange liquid. By setting up the sixth diversion medium pipeline 104, the fifth pump body 106, the third evaporator 63, and the third evaporator 64, the heat exchange liquid can more effectively absorb the heat in the exhaust air each time it comes into contact with the exhaust air, which significantly improves the heat recovery efficiency of the exhaust air.
[0055] In this embodiment, the processing system also includes a seventh diversion medium pipeline 105. Both the seventh diversion medium pipeline 105 and the sixth diversion medium pipeline 104 flow through the third evaporator 63, so that the heat exchange medium in the seventh diversion medium pipeline 105 and the heat exchange liquid in the sixth diversion medium pipeline 104 exchange heat, and then exchange heat with the low temperature liquid to form a high temperature liquid.
[0056] Specifically, heat exchange is carried out through the heat exchange medium in the seventh diversion medium pipeline 105 and the heat exchange liquid in the sixth diversion medium pipeline 104. This not only avoids overheating of the heat exchange liquid flowing into the third spray section 103, but also ensures that the heat exchange medium in the seventh diversion medium pipeline 105 can be fully heated before exchanging heat with the liquid to be heated to form a heated liquid.
[0057] In this embodiment, the processing system further includes a fourth heating element 64 and an eighth diversion medium pipeline 107. Both the seventh diversion medium pipeline 105 and the eighth diversion medium pipeline 107 flow through the fourth heating element 64, so that the heat exchange medium in the seventh diversion medium pipeline 105 can exchange heat with the low-temperature liquid in the eighth diversion medium pipeline 107.
[0058] Specifically, heat exchange is performed between the heat exchange medium in the seventh branch medium pipeline 105 and the liquid to be heated in the eighth branch medium pipeline 107, ensuring that the liquid to be heated in the eighth branch medium pipeline 107 can be fully heated to form a heated liquid.
[0059] Specifically, the seventh diversion medium pipeline 105 includes two liquid distribution pipe sections. The inlet and outlet ends of one liquid distribution pipe section are respectively connected to the outlet end of a heat exchange channel in the third evaporator 63 and the inlet end of a heat exchange channel in the fourth heating element 64. The outlet and inlet ends of the other liquid distribution pipe section are respectively connected to the inlet end of a heat exchange channel in the third evaporator 63 and the outlet end of a heat exchange channel in the fourth heating element 64. The sixth diversion medium pipeline 104 flows through another heat exchange channel in the third evaporator 63, and the eighth diversion medium pipeline 107 flows through another heat exchange channel in the fourth heating element 64. A second compressor 641 and a second expansion valve 661 are provided on the seventh diversion medium pipeline 105. The second compressor 641 is located between the outlet end of the third evaporator 63 and the inlet end of the fourth heating element 64, and the second expansion valve 661 is located between the inlet end of the third evaporator 63 and the outlet end of the fourth heating element 64. The low-pressure heat exchange medium in the third evaporator 63 changes from a liquid to a gaseous state, absorbing heat from the heat exchange liquid flowing out of the solution heat exchanger 61. Then, the heat exchange medium in the third evaporator 63 flows into the second compressor 641. The second compressor 641 compresses the low-pressure heat exchange medium from the third evaporator 63 into a high-pressure heat exchange medium. The high-pressure heat exchange medium then flows into the fourth heating element 64. The high-pressure heat exchange medium in the fourth heating element 64 liquefies to exchange heat with the low-temperature liquid in the eighth diversion medium pipeline 107. The high-pressure heat exchange medium flowing out of the fourth heating element 64 then flows into the second expansion valve 661. The second expansion valve 661 depressurizes the high-pressure heat exchange medium, turning it into a low-pressure heat exchange medium, which then flows back into the third evaporator 63, achieving the recycling of the heat exchange medium. Simultaneously, the second expansion valve 661 controls the flow rate of the heat exchange medium, ensuring sufficient heat exchange medium evaporation in the third evaporator 63 while preventing excessive heat exchange medium from entering, causing incomplete evaporation or "liquid slugging."
[0060] Optionally, the liquid to be heated 2 is high-temperature hot water return flowing out of the heating channel of the drying unit 4, and the heating liquid 1 is high-temperature hot water supply flowing into the heating channel of the drying unit 4.
[0061] Specifically, such as Figure 1As shown, the flow path of the fresh air is as follows: second cooling element 11, third cooling element 21, fourth cooling element 31, solution dehumidification element 41, second heating element 12, third heating element 22, first heating element 72, ventilation area of drying unit 4, first cooling element 71, solution regeneration element 51 and solution heat exchanger 61, and then discharged to the outside from solution heat exchanger 61. The processing system of this utility model has a ventilation mode and a dehumidification mode. When the processing system is in dehumidification mode, the fresh air flowing into the processing system has a higher humidity. The fresh air with higher humidity is first pre-cooled and dehumidified by the second cooling element 11, third cooling element 21 and fourth cooling element 31, and then cooled and dehumidified to the required moisture content by the solution dehumidification element 41. The dehumidified fresh air is heated by the second heating element 12 and the third heating element 22, and then sent to the ventilation area of the drying unit 4 through the first heating element 72 to form exhaust air (at this time, the first heating element 72 does not heat the fresh air). The exhaust air flows through the first cooling element 71 (at this time, the first cooling element 71 does not cool the exhaust air), and then flows into the solution regeneration element 51 for isenthalpic regeneration. The heat in the exhaust air is then recovered through the solution heat exchange element 61 and transferred to the liquid to be heated 2 to heat the liquid to be heated 2 to form heated liquid 1. The heated liquid 1 can be used to enter the heating channel of the drying unit 4 to heat and dry the items to be dried. Then the exhaust air is discharged to the outside from the solution heat exchange element 61.
[0062] When the processing system is in ventilation mode, the fresh air flowing into the system has low humidity, making it low-humidity fresh air that does not require dehumidification. The fresh air first flows through the second cooling element 11, the third cooling element 21, the fourth cooling element 31, the solution dehumidifier 41, the second heating element 12, and the third heating element 22 (at this time, the second cooling element 11, the third cooling element 21, the fourth cooling element 31, and the solution dehumidifier 41 do not cool or dehumidify the fresh air, and the second heating element 12 and the third heating element 22 do not heat the fresh air), and then flows into... The first heating element 72 heats the air, which is then sent to the ventilation area of the drying unit 4 to form exhaust air. The exhaust air flows through the first cooling element 71 for cooling and then through the solution regeneration element 51 (at this time, the heat exchange medium in the solution regeneration element 51 stops exchanging heat with the exhaust air). It then flows into the solution heat exchanger 61 to recover the heat from the exhaust air and transfer it to the liquid to be heated 2, thus heating the liquid to form heated liquid 1. Heated liquid 1 can be used to heat and dry the workpiece in the heating channel of the drying unit 4. This invention features a highly integrated processing system that fully recovers exhaust air energy to regenerate the dehumidifying solution and prepare heated liquid 1 as a drying heat source, resulting in low energy consumption and reduced operating costs.
[0063] Specifically, the first heating element 72 and the first cooling element 71 have pumps inside, which can control the heat exchange medium inside the first heating element 72 and the first cooling element 71 to stop flowing. When the processing system is in dehumidification mode, the heat exchange medium inside the first heating element 72 and the first cooling element 71 stops flowing, so that the temperature of the heat exchange medium inside the first heating element 72 is almost the same as the temperature of the incoming fresh air, and the temperature of the heat exchange medium inside the first cooling element 71 is almost the same as the temperature of the incoming exhaust air. Therefore, the first heating element 72 will not heat the incoming fresh air, and the first cooling element 71 will not cool the incoming exhaust air.
[0064] Specifically, the second heating element 12 and the second cooling element 11 have pumps inside, which can control the heat exchange medium inside the second heating element 12 and the second cooling element 11 to stop flowing. When the processing system is in ventilation mode, the heat exchange medium inside the second heating element 12 and the second cooling element 11 stops flowing, so that the temperature of the heat exchange medium inside the second heating element 12 and the second cooling element 11 is almost the same as the temperature of the low-humidity fresh air flowing through it. Therefore, the second cooling element 11 will not cool or dehumidify the low-humidity fresh air, and the second heating element 12 will not heat the low-humidity fresh air.
[0065] Specifically, the third heating element 22 and the third cooling element 21 have pumps inside, which can control the heat exchange medium inside the third heating element 22 and the third cooling element 21 to stop flowing. When the processing system is in ventilation mode, the heat exchange medium inside the third heating element 22 and the third cooling element 21 stops flowing, so that the temperature of the heat exchange medium inside the third heating element 22 and the third cooling element 21 is almost the same as the temperature of the low-humidity fresh air flowing through it. Therefore, the third cooling element 21 will not cool or dehumidify the low-humidity fresh air, and the third heating element 22 will not heat the low-humidity fresh air.
[0066] Specifically, when the processing system is in ventilation mode, the solution dehumidification component 41 stops operating, the solution regeneration component 51 stops operating, the solution dehumidification component 41 does not cool and dehumidify the fresh air, the heat exchange medium in the solution regeneration component 51 stops exchanging heat with the exhaust air; the fourth cooling component 31 stops introducing the low-temperature heat exchange medium 3, so that the temperature of the heat exchange medium in the fourth cooling component 31 is almost the same as the temperature of the low-humidity fresh air flowing through it, so the third cooling component 21 does not play a role in cooling and dehumidifying the low-humidity fresh air.
[0067] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0068] The processing system of this utility model includes a solution dehumidification component 41, a heating component, a solution regeneration component 51, a drying unit 4, and a solution heat exchanger 61. When fresh air with high humidity flows through the solution dehumidification component 41, it comes into contact with the dehumidification solution for heat exchange, thus cooling and dehumidifying the fresh air. At the same time, the dehumidification solution in the solution dehumidification component 41 is diluted. Then, the fresh air flowing out of the solution dehumidification component 41 flows through the heating component for heating. The heated fresh air flowing out of the heating component flows into the ventilation area of the drying unit 4 to form high-temperature exhaust air. Then, the high-temperature exhaust air flowing out of the drying unit 4 flows through the solution regeneration component 51 for heat exchange with the regeneration solution, thus cooling and dehumidifying the fresh air. The regeneration solution is concentrated, and a portion of the concentrated regeneration solution in the solution regeneration unit 51 enters the solution dehumidification unit 41 to maintain the concentration of the dehumidification solution and achieve continuous cooling and dehumidification of the fresh air. Then, the high-temperature exhaust air flowing out of the solution regeneration unit 51 flows into the solution heat exchanger 61 and exchanges heat with the heat exchange liquid inside the solution heat exchanger 61. The heat exchange liquid then exchanges heat with the liquid to be heated 2 outside the solution heat exchanger 61, so that the heat of the high-temperature exhaust air is transferred to the liquid to be heated 2 through the heat exchange liquid, so that the liquid to be heated 2 is heated to form the heating liquid 1. The heating liquid 1 is used to enter the heating channel of the heater so that the heater outputs high-temperature air to heat and dry the items to be dried. Therefore, the processing system of this utility model can make full use of the heat in the high-temperature exhaust air flowing out of the drying unit 4. On the one hand, the high-temperature exhaust air can be used to concentrate the regenerated solution in the solution regeneration component 51, and the concentration of the dehumidifying solution in the solution dehumidifying component 41 can be maintained through interstage flow solution exchange, thereby achieving cooling and dehumidification of the fresh air. The rotary dehumidifier is no longer needed, which greatly saves the energy required to cool and dehumidify the fresh air. On the other hand, the heat in the high-temperature exhaust air can be recovered by the solution heat exchange component 61, so that the liquid to be heated 2 is heated to form the heating liquid 1. The heating liquid 1 can be used as the heat energy source of the heater, so that the heat energy source of the heater does not depend on the boiler hot water, which greatly saves the energy required to dry the parts to be dried. Thus, the processing system of this utility model has low operating energy consumption, significantly reduces the operating cost of the processing system, and improves the economy of the processing system.
