Description

Technical Field

[0001] The utility model relates to the technical field of drying boxes, in particular to a heat exchange core installation device, a dehumidification waste heat recovery system and a double-sided air inlet drying box. Background Art

[0002] With energy conservation and emission reduction becoming a global consensus, more and more consumers are choosing products that prioritize environmental protection, sustainability, and energy efficiency. This trend is particularly evident in the manufacturing industry, where the call for increasing output by reducing energy consumption is growing.

[0003] In the current agricultural product drying industry, drying rooms and mesh belt dryers have different applications. In terms of drying targets, drying rooms are suitable for drying small quantities of high-quality materials, while mesh belt dryers are suitable for drying large quantities of materials. From an exhaust perspective, the moisture content of the exhaust air from drying rooms is generally lower than that from mesh belt dryers.

[0004] Because of the varying moisture content of exhaust air, whether from a drying room or a mesh belt drying box, directly recycling the exhaust air back into the heating equipment can not only affect the airflow balance of the heating equipment but can also cause internal corrosion. Therefore, in actual production equipment, to extend the life of the equipment, a dehumidification port is typically located on the top surface of the drying equipment, directing the exhaust air away from the equipment to prevent high-water content from affecting the equipment. Utility Model Content

[0005] On the first aspect, the purpose of the present invention is to provide a heat exchange core installation device to solve the problem that when the dehumidified gas is recycled based on the existing heat exchange core, the service life of the equipment in contact with the dehumidified gas is easily affected due to the high water content of the dehumidified gas.

[0006] In order to solve the above problems, the present invention adopts the following technical means:

[0007] A heat exchange core installation device, comprising:

[0008] The core block positioning portion is used to embed the heat exchange core and is constructed with a fresh air duct and a hot and humid air duct;

[0009] an air passage portion connected to the bottom surface of the core block positioning portion, wherein an air passage cavity communicating with the hot and humid air passage is constructed inside the air passage portion, an air outlet channel communicating with the air passage cavity is constructed on a side wall of the air passage portion, and a condensed water collection portion is constructed on the bottom surface of the air passage portion;

[0010] The air outlet channel is connected to a dehumidification mechanism.

[0011] In some embodiments, a receiving plate for supporting the heat exchange core is constructed in the core block positioning portion, and the side walls of the core block positioning portion are respectively constructed with a first opening and a second opening, and the first opening and the second opening are combined with the heat exchange inner channel to form the fresh air duct.

[0012] In some embodiments, the first opening or the second opening is used to install the heat exchange core.

[0013] Furthermore, the present application provides a heat exchange core installation device, which can install the heat exchange core, and after the fresh air and the dehumidified air undergo heat exchange in the fresh air duct and the hot and humid air duct respectively, the temperature of the fresh air increases and the temperature of the dehumidified air decreases, thereby realizing the conversion of heat energy. In addition, after the dehumidified air and the fresh air undergo heat exchange, the moisture carried in the dehumidified air is condensed, and the generated condensed water drips and is collected in the condensed water collection part. The dehumidified air with reduced water content is discharged from the side air outlet channel, while the condensed water remains in the condensed water collection part, preventing it from following the dehumidified air flow into the dehumidification mechanism. In this way, the temperature of the dehumidified air passing through the dehumidification mechanism is reduced and the water content is reduced, thereby preventing the high-temperature and high-humidity dehumidified air from causing rust to the dehumidification mechanism or the equipment it flows through.

[0014] Secondly, the utility model also provides a dehumidification waste heat recovery system to solve the problem that the current dehumidification air from the drying box is directly discharged and difficult to be directly utilized for a long time.

[0015] In order to solve the above problems, the present invention adopts the following technical means:

[0016] A dehumidification waste heat recovery system, comprising:

[0017] The moisture collecting mechanism is used to collect the moisture discharged from the drying box and is connected to the top surface of the drying box;

[0018] The dehumidification air duct includes a moisture inlet connection mechanism and a heat exchange exhaust mechanism. The heat exchange exhaust mechanism includes a core block positioning portion in which a heat exchange core is installed and an air flow portion. A fresh air duct and a humid hot air duct are constructed in the core block positioning portion through the heat exchange core. One end of the humid hot air duct is connected to the moisture collection mechanism through the moisture inlet connection mechanism, and the other end is connected to the air flow portion. The two ends of the fresh air duct are respectively connected to the outside and the air inlet end of the heating mechanism. The side wall of the air flow portion is configured with an air outlet channel for discharging air.

[0019] The dehumidification mechanism is connected to the air outlet channel and is used to extract the gas in the air flow portion.

[0020] In some embodiments, the moisture collection mechanism includes a dehumidification pipe connected to the top surface of the drying box, the air outlet end of the dehumidification pipe is connected to the air collection pipe, and the air inlet end of the hot and humid air duct is connected to the air collection pipe through the moisture inlet connection mechanism.

[0021] In some embodiments, a condensation water collecting portion is constructed at the bottom of the wind passage portion and is located below the air outlet end of the hot and humid air duct, and a drainage pipe connected to the condensation water collecting portion is constructed on the side of the wind passage portion.

[0022] In some embodiments, a valve switch is provided in the drain pipe.

[0023] Furthermore, the present application relates to a dehumidification waste heat recovery system, which, when used in a drying box, can collect the high-humidity and high-temperature dehumidified air generated inside the drying box through a moisture collection mechanism. Under the action of the dehumidification mechanism, the dehumidified air discharged from the drying box passes through the hot and humid air duct formed by the heat exchange core, and is then discharged from the air outlet channel. The external fresh air passes through the fresh air duct formed by the heat exchange core and enters the heating mechanism. After the dehumidified air and the fresh air complete the heat exchange in the heat exchange core, the heat carried by the dehumidified air is absorbed by the fresh air and enters the heating mechanism for reuse, thereby achieving the purpose of preheating and recycling the dehumidified air. In addition, the moisture carried by the dehumidified air condenses during the heat exchange process, reducing the water content of the dehumidified air. At the same time, the condensed water drips to the bottom surface of the air flow section, and the dehumidified air with reduced water content is discharged from the air outlet channel, so that the condensed water and the dehumidified air are separated. In this way, the humidity and temperature of the dehumidified air flowing out of the air outlet channel are reduced, thereby reducing the corrosion caused by the dehumidified air to the equipment it flows through, thereby improving the service life of the entire drying box.

[0024] On the third aspect, the utility model also provides a double-sided air inlet drying box, so that the double-sided air inlet drying box can recover heat from the discharged moisture, thereby achieving the purpose of energy saving and emission reduction.

[0025] In order to achieve the above purpose, the utility model adopts the following technical means:

[0026] A double-sided air inlet drying box, comprising a drying chamber and a first wind box and a second wind box provided on both sides of the drying chamber, and also comprising the aforementioned dehumidification and waste heat recovery system;

[0027] It comprises at least two dehumidification air ducts, and the air outlet ends of the heating mechanism respectively connected to the two dehumidification air ducts are respectively connected to the first wind box and the second wind box.

[0028] In some embodiments, the two dehumidification air ducts are both provided on one side of the first air box;

[0029] The air outlet end of one of the heating mechanisms extends into the first wind box and discharges air from the middle of the first wind box;

[0030] The air outlet end of the other heating mechanism extends into the first wind box and passes through the bottom of the drying chamber and then extends into the second wind box, and the air is discharged from the middle of the second wind box.

[0031] The present application relates to a double-sided air-inlet drying oven, in which the dehumidified air generated during the drying process can be completely collected into a moisture collection mechanism. After the dehumidified air enters the dehumidification air duct and completes heating of the fresh air, it is blown into the first and second air boxes respectively through different heating mechanisms, thereby utilizing the high temperature carried by the dehumidified air to achieve energy conservation and reduce the heat discharged into the air by the dehumidified air, thereby achieving the effect of emission reduction. At the same time, after the dehumidified air has been processed by the dehumidification waste heat recovery system, the equipment that the dehumidified air passes through after completing the heat exchange can be prevented from being corroded by the high-temperature and high-humidity dehumidified air, thereby greatly improving the service life of the entire double-sided air-inlet drying oven.

[0046] Please combine first Figures 1 to 3 As shown, a heat exchange core installation device includes:

[0047] The core block positioning portion 100 is used to embed the heat exchange core 200 and is configured with a fresh air duct 300 and a hot and humid air duct 400;

[0048] The core block positioning portion 100 may be a square tube structure or other ventilation structure, wherein the air inlet end of the square tube is used to receive the hot and humid air, and the air outlet end is used to discharge the hot and humid air;

[0049] The aforementioned fresh air duct 300 refers to a component used to combine with the air duct for passing fresh air in the heat exchange core 200 to allow fresh air to pass through.

[0050] In this embodiment, the fresh air duct 300 can be composed of a first opening and a second opening arranged on the side wall of the core block positioning part 100 and a channel in the heat exchange core 200 for fresh air to flow through, wherein the fresh air flows into the heat exchange core 200 from the first opening and then flows out from the second opening.

[0051] In this embodiment, the hot and humid air duct 400 is composed of the air inlet end and air outlet end of the core block positioning part 100 as the aforementioned square tube structure and the channel for the hot and humid air to flow through the heat exchange core 200, wherein the hot and humid air passes through the air inlet end of the square tube into the heat exchange core 200, and then flows out from the long air outlet end of the square tube.

[0052] Moreover, in this embodiment, the aforementioned hot and humid air duct 400 is arranged vertically.

[0053] Thus, the heat exchange core 200 installation device in this embodiment further includes an air passage 500 , which is connected to the bottom surface of the core block positioning portion 100 and presents an upper and lower layout structure with the core block positioning portion 100 ;

[0054] The air passage portion 500 is internally structured with an air passage cavity 600 that is in communication with the hot and humid air passage 400. After the hot and humid air flows through the heat exchange core 200, it enters the air passage portion 500.

[0055] The aforementioned air flow section 500 can be another square tube structure connected to the aforementioned square tube core block positioning section 100. Its inner cavity serves as an air flow chamber 600. The top surface of the air flow section 500 is provided with an opening for the flow of moist hot air into the air inlet chamber. The sidewalls of the air flow section 500 are configured with an air outlet duct 700 connected to the air flow chamber 600. This allows the moist hot air, after flowing vertically downward into the air flow chamber 600, to be redirected by impacting the bottom surface of the air flow section 500. The bottom surface of the air flow section 500 is a closed platform structure. The redirected moist hot air, impacting the bottom surface of the air flow section 500, flows out through the air outlet duct 700 provided in the sidewalls of the air flow section 500. Furthermore, due to the closed structure of the bottom surface of the air flow section 500, the bottom surface of the air flow section 500 forms a condensate collection section 800 located below the aforementioned heat exchange core 200. After the fresh air and the moist hot air complete the heat exchange in the heat exchange core 200 , the condensed water droplets generated by condensation in the moist hot air can drip into the condensation collection portion formed on the bottom surface of the air flow portion 500 .

[0056] At the same time, combined with the redirection of the humid and hot air, it flows out from the side wall of the air flow section 500, so that the condensed water is retained in the condensed water collection section 800 at the bottom of the air flow section 500. This not only separates the moisture flowing out of the air flow section 500 from the condensed water to reduce the water content, but also prevents the condensed water from following the wind flow and moving downstream to avoid rusting of downstream equipment.

[0057] The air outlet passage 700 is connected to a dehumidification mechanism 900. Specifically, in this embodiment, the dehumidification mechanism 900 is a dehumidification pump. The dehumidification pump continuously applies negative pressure to the air passage 600, allowing the dehumidified air to be continuously discharged from the air outlet passage 700. Ultimately, the dehumidified air, with reduced humidity and temperature, is discharged through the dehumidification pump.

[0058] Furthermore, in this embodiment, the heat exchange core 200 can be installed in the core block positioning portion 100 by installing two parallel receiving plates 1000 on the inner wall of the core block positioning portion 100. The receiving plates 1000 extend in the same direction as the communication between the first opening and the second opening. This allows the heat exchange core 200 to be inserted through either the first or second opening and then slid onto the receiving plates 1000 until it is fully inserted into the core block positioning portion 100.

[0059] Furthermore, in this embodiment, a drain pipe 1100 is installed on the side wall of the air flow portion 500. The drain pipe 1100 is connected to the condensate collection portion 800. This allows liquid accumulated in the condensate collection portion 800 to be drained from the drain pipe 1100, thereby preventing a large amount of condensate from accumulating and causing some of the liquid to escape from the air outlet 700 along with the wind flow.

[0060] To prevent the dehumidification mechanism 900 from causing air backflow into the drain pipe 1100 and thereby generating a large number of bubbles in the liquid in the condensate collection portion 800, a valve is installed in the drain pipe 1100 to control the opening and closing of the drain pipe 1100. When the dehumidification mechanism 900 is operating, the valve is closed, and when the dehumidification mechanism 900 is draining, the valve is open.

[0061] A heat exchange core installation device involved in this embodiment is used to install and position the heat exchange core 200, so that after the fresh air and dehumidified air complete heat exchange in the heat exchange core 200, the moisture content of the dehumidified air subsequently entering the dehumidification mechanism 900 is reduced, thereby slowing down equipment corrosion caused by the reuse of the dehumidified air. Example

[0062] In this embodiment, please refer to Figures 1 to 7 As shown, a dehumidification waste heat recovery system is disclosed, which is used to collect a large amount of dehumidified gas generated during the drying process of the drying box and reuse its heat energy. It can also effectively reduce the corrosion caused by the large amount of dehumidified gas reuse on the operation of the entire equipment.

[0063] Specifically, the dehumidification waste heat recovery system involved in this embodiment includes:

[0064] The moisture collecting mechanism 1200 is used to collect the moisture discharged from the drying box and is connected to the top surface of the drying box;

[0065] The moisture collection mechanism 1200 can be connected to a plurality of dehumidification pipes 1210 on the top surface of the drying box, and then connected to an air collection pipe 1220. The air collection pipe 1220 can be a double-layered air duct. In this way, during the drying process, the high-temperature and high-humidity exhaust air continuously generated in the drying box can continuously enter the air collection pipe 1220 through each dehumidification pipe 1210 and then flow out from the air outlet of the air collection pipe 1220.

[0066] In this embodiment, the aforementioned plurality of dehumidification pipes 1210 are equidistantly spaced from one another and arranged sequentially along the length of the air collecting pipe 1220. This allows the dehumidified air generated within the drying box to flow relatively quickly and evenly from the dehumidification pipes 1210 into the air collecting pipe 1220. This improves the dehumidification effect by reducing the time the dehumidified air remains at the top of the drying box, and by collecting the dehumidified air, the efficiency of its collection and reuse is increased.

[0067] At the same time, the dehumidification waste heat recovery system in this embodiment also includes a dehumidification air duct. The dehumidification air duct here is mainly used to utilize the internal heat exchange core 200 to allow fresh air and dehumidified air to exchange heat, recycle the waste heat in the dehumidified air, and at the same time reduce the humidity of the dehumidified air to avoid the large amount of moisture contained in the dehumidified air after reuse, which causes subsequent equipment to be easily corroded.

[0068] Specifically, the dehumidification duct includes a moisture inlet and outlet mechanism 1300 and a heat exchange exhaust mechanism. The heat exchange exhaust mechanism includes a core block positioning portion 100 in which a heat exchange core 200 is installed, and an air passage portion 500. In this embodiment, the core block positioning portion 100 is used to install the heat exchange core 200. After the heat exchange core 200 is installed, a fresh air duct 300 and a humid hot air duct 400 are constructed in the core block positioning portion 100 through the heat exchange core 200. Specifically, the fresh air inlet and outlet channels of the heat exchange core 200 are used to form the fresh air duct 300 for fresh air to pass through. The humid hot air duct 400 for dehumidification air to pass through is formed in the heat exchange core 200.

[0069] In this embodiment, the aforementioned moisture inlet connection mechanism 1300 can be connected to the top of the heat exchange and moisture removal mechanism, namely, the air inlet section of the moist hot air duct 400. The moist air exhausted from the top of the drying box is collected in the moisture collection mechanism 1200, then enters the aforementioned moist hot air duct 400 through the moisture inlet connection mechanism 1300. After completing heat exchange with fresh air in the heat exchange core 200, it enters the air flow section 500. The fresh air after heat exchange enters the air inlet of the heating mechanism 1400, recycling the heat in the moist air. The aforementioned heating mechanism 1400 can be a gas-fired hot air furnace.

[0070] In this embodiment, the air passage 500 may be a pipeline structure connected to the hot and humid air duct 400 , and the air passage 500 is used to allow the dehumidified air after the heat exchange to be discharged through the air outlet channel 700 .

[0071] In this embodiment, the dehumidification and waste heat recovery system further includes a dehumidification mechanism 900 , which is connected to the air outlet channel 700 and is used to extract the gas in the air flow portion 500 .

[0072] In this embodiment, the dehumidification mechanism 900 is used to continuously extract air from the air flow passage 500, thereby drawing the dehumidified air within the drying chamber into the moisture collection mechanism 1200. After passing through the dehumidification air duct, the dehumidified air is discharged from the dehumidification mechanism 900. Specifically, the dehumidification mechanism 900 can be a dehumidification pump connected to the side wall of the air flow passage 500.

[0073] Furthermore, the bottom surface of the aforementioned air flow section 500 is provided with a planar structure, and the planar structure is located directly below the outlet end of the moist hot air duct 400. The planar structure serves as a condensate collection portion 800, which is used to collect condensate generated from the dehumidified air after heat exchange. In this way, the condensate dripping downward from the heat exchange core 200 can drip onto the bottom surface of the air flow section 500, while the dehumidified air, whose humidity and temperature have been reduced, changes direction after colliding with the bottom surface of the air flow section 500 and is discharged from the air outlet channel 700 on the side wall of the air flow section 500. This achieves the separation of the dehumidified air and the condensate, preventing the condensate from continuing to flow along the system with the dehumidified air, thereby reducing the corrosion of the subsequent piping system.

[0074] Furthermore, condensate collected in the condensate collection section 800 can be drained through a drain pipe 1100 located on the side wall of the air flow section 500. This drain pipe 1100 is located on the side wall of the air flow section 500 and communicates with the condensate collection section 800. A valve switch is installed within the drain pipe, opening it when needed and closing it when not. This prevents gas backflow from the drain pipe 1100, which could cause a large number of bubbles to form in the liquid in the condensate collection section 800. When the dehumidification mechanism 900 is operating, the valve is closed, and when it is discharging liquid, the valve is open.

[0075] Therefore, this embodiment provides a dehumidification waste heat recovery system for a drying box. The high-temperature, high-humidity gas generated in the drying box can be evenly and quickly discharged from the top into the moisture collection mechanism 1200 and then into the dehumidification duct. After completing heat exchange with the fresh air in the dehumidification duct, the heated fresh air enters the heating mechanism 1400 to recycle the heat of the dehumidified air. The dehumidified air, with a lower temperature and lower humidity, passes through the air flow section 500, where it is separated from the condensed water and discharged through the dehumidification mechanism 900. This achieves the goals of energy conservation and emission reduction, and slows down equipment corrosion.

[0076] In this embodiment, based on the previous description, a double-sided air inlet drying box is also provided in this embodiment. Specifically, the dehumidification and waste heat recovery system involved in this embodiment is used in the double-sided air inlet drying box.

[0077] A double-sided air inlet drying oven includes a drying chamber 1500 and a first air box 1600 and a second air box 1700 located on the sides of the drying chamber 1500. Hot air used to dry the material in the drying chamber 1500 is blown into the first air box 1600 and the second air box 1700 by a heating mechanism 1400. The hot air then passes through the communication structure between the first air box 1600 or the second air box 1700 and the drying chamber, and then enters the drying chamber for drying.

[0078] After drying is complete, the dehumidified air generated within the drying chamber 1500 is discharged from the top surface of the drying chamber 1500 and enters the aforementioned moisture collection mechanism 1200. Furthermore, at least two of the aforementioned dehumidification air ducts are connected to the dehumidification collection mechanism. Specifically, the dehumidification collection mechanism is connected to at least two moisture inlet connection mechanisms 1300, two core block positioning portions 100, two air passage portions 500, and two heating mechanisms 1400. The air outlet ends of the heating mechanisms 1400, respectively connected to the two dehumidification air ducts, are connected to the first and second air boxes 1600 and 1700, respectively.

[0079] In this way, the dehumidified air discharged from the drying chamber 1500 and entering the moisture collection mechanism 1200 can be divided into two parts, each passing through different dehumidification ducts to exchange heat with the fresh air passing through two different fresh air ducts 300. The fresh air, which has recovered heat, is then utilized by at least two heating mechanisms 1400, and the hot air for drying is then blown into the first and second air boxes 1600 and 1700, respectively. This ensures that the first and second air boxes 1600 and 1700 evenly distribute air from both sides of the drying chamber 1500.

[0080] Furthermore, in this embodiment, to facilitate maintenance when the dehumidification and waste heat recovery system is used in a double-sided air inlet drying box, the at least two dehumidification ducts are both located on one side of the first air box 1600. This allows maintenance personnel to perform maintenance on either side of the first air box 1600 or the second air box 1700 without having to move between the two sides.

[0081] Because at least two dehumidification ducts are arranged on the same side, while ensuring the integrity of the equipment and reducing the space occupied by the equipment, in order to allow the hot air generated by the heating mechanism 1400 to directly enter the first wind box 1600 and the second wind box 1700, the air outlet end of one of the at least two heating mechanisms 1400 extends into the first wind box 1600 and discharges air from the middle of the first wind box 1600;

[0082] The air outlet of the other heating mechanism 1400 extends into the first wind box 1600, passes through the bottom of the drying chamber 1500, and then extends into the second wind box 1700, discharging air from the middle of the second wind box 1700. Furthermore, the portion extending into the first wind box 1600 and the drying chamber 1500 is designed as an insulated duct to reduce the heat exchange between the hot air and the first wind box 1600 or the drying chamber's internal environment during the hot air delivery process, thereby reducing the temperature of the hot air entering the second wind box 1700. Example

[0083] In this embodiment, based on the embodiment 2, the dehumidification air duct in the embodiment is described in more detail.

[0084] Specifically, the heat exchange exhaust mechanism in Example 2 has the same structure as the heat exchange core 200 mounting device in Example 1.

[0085] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
