Description

Technical Field

[0001] This utility model belongs to the field of dehumidification technology, specifically relating to a dehumidification device that utilizes the waste heat of an air compressor. Background Technology

[0002] Currently, in the production and processing of honeycomb paperboard, the finished honeycomb paperboard needs to be stored in warehouses. However, the moisture content of the honeycomb paperboard itself needs to be maintained within a certain range to ensure its performance indicators. Due to the influence of the humidity in the warehouse environment, the moisture content of the honeycomb paperboard is often high, so the warehouse needs to be heated and dehumidified. However, existing warehouses often use independent heating equipment, which has high energy consumption. In addition, the lubrication system of the air compressor used in other production stages of honeycomb paperboard also generates waste heat. Most of this waste heat is directly exchanged by coolers, resulting in heat waste, which needs to be improved. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a dehumidification device that utilizes the waste heat of an air compressor, which can effectively use the waste heat of the air compressor to heat the dehumidification room, thereby solving the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a dehumidification device utilizing waste heat from an air compressor, comprising an air compressor lubricating oil output pipeline, an oil cooler, an oil filter, a dehumidification chamber, an air heat exchanger, and at least two dehumidifiers. The tail end of the air compressor lubricating oil output pipeline is connected in parallel to a first branch pipeline and a second branch pipeline. The first branch pipeline is connected to the oil inlet of the oil filter. The tail end of the second branch pipeline is connected in parallel to a first heat exchange conveying pipeline and a second heat exchange conveying pipeline. The first heat exchange conveying pipeline is connected to the oil inlet of the oil cooler. The cooler's oil outlet is connected to the oil filter's inlet via a first oil outlet pipe. The air heat exchanger and dehumidifier are both located in a dehumidification room. The second heat exchange conveying pipe is detachably connected to the air heat exchanger's oil inlet. The air heat exchanger's oil outlet is detachably connected to a second oil outlet pipe, which is connected to the oil filter's inlet. Pipe valves are installed on the first branch pipe, the second branch pipe, the first heat exchange conveying pipe, the second heat exchange conveying pipe, the first oil outlet pipe, and the second oil outlet pipe. A temperature control valve is installed on the second branch pipe.

[0005] Preferably, the air heat exchanger includes a base, a hollow oil inlet main plate is fixedly mounted on the top of the base, a plurality of evenly distributed hollow oil inlet branch plates are fixedly connected to the top of the oil inlet main plate, a plurality of evenly distributed spiral heat dissipation coils are fixedly connected to the top of the oil inlet branch plates, heat dissipation fins are evenly distributed on the outer wall of the heat dissipation coils, the top of the heat dissipation coils on the same oil inlet branch plate are fixedly connected to the same hollow oil outlet branch plate, the top of the oil outlet branch plate is fixedly connected to the same hollow oil outlet main plate, the oil inlet of the air heat exchanger is opened on one side of the oil inlet main plate, and the oil outlet is opened on the side of the oil outlet main plate away from the oil inlet, the tail end of the second heat exchange delivery pipeline is fixedly connected to a first flexible hose, the first flexible hose is connected to the oil inlet of the air heat exchanger through a first quick connector, and the head end of the second oil outlet pipeline is fixedly connected to a second flexible hose, the second flexible hose is connected to the oil outlet of the air heat exchanger through a second quick connector.

[0006] Preferably, hydraulic cylinders are vertically fixed at the four corners of the base. Inverted U-shaped support legs are fixedly sleeved on the outside of the cylinder body of the hydraulic cylinder. The piston rod of the hydraulic cylinder faces downward and a caster is installed on its bottom end.

[0008] Preferably, the temperature control valve is a 75°C temperature control valve and a 100°C temperature control valve connected in series.

[0009] Preferably, a booster pump is provided on the second heat exchange delivery pipeline.

[0010] The beneficial effects of this invention are as follows: During use, the finished honeycomb cardboard is placed in a dehumidification room for storage. When the temperature of the lubricating oil supplied from the air compressor's lubricating oil output line is low, it can be directly supplied to the oil filter via the first branch line. After filtration by the oil filter, the lubricating oil is then returned to the air compressor. When the temperature of the lubricating oil supplied from the air compressor's lubricating oil output line is high and the dehumidification room is not required, the lubricating oil can be supplied to the oil cooler via the second branch line and the first heat exchange conveying line. After cooling by the oil cooler, the cold lubricating oil is filtered by the oil filter and then returned to the air compressor. When the dehumidification room requires heating and dehumidification, hot lubricating oil can be transported to the air heat exchanger via the second branch pipe and the second heat exchange conveying pipe. The air heat exchanger transfers the heat from the hot lubricating oil to the air in the dehumidification room. The cooled lubricating oil is then transported to the oil filter, filtered, and returned to the air compressor. The heated air in the dehumidification room effectively evaporates the moisture from the honeycomb cardboard. The dehumidifier then condenses and discharges the moisture from the air in the dehumidification room, effectively reducing the humidity and ensuring the storage quality of the honeycomb cardboard. This method effectively utilizes the waste heat from the air compressor's lubricating oil system to heat and dehumidify the dehumidification room storing the honeycomb cardboard, resulting in greater energy efficiency, environmental friendliness, improved product quality, and greater practicality.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 to 4 As shown, a dehumidification device utilizing waste heat from an air compressor includes an air compressor lubricating oil output pipeline 1, an oil cooler 2, an oil filter 3, a dehumidification chamber 4, an air heat exchanger 5, and at least two dehumidifiers 6. The air compressor lubricating oil output pipeline 1 is connected in parallel to a first branch pipeline 7 and a second branch pipeline 8. The first branch pipeline 7 is connected to the oil inlet of the oil filter 3. The second branch pipeline 8 is connected in parallel to a first heat exchange conveying pipeline 9 and a second heat exchange conveying pipeline 10. The first heat exchange conveying pipeline 9 is connected to the oil inlet of the oil cooler 2. The oil outlet of the oil cooler 2 is connected to the oil inlet of the oil filter 3 through a first oil outlet pipeline 11. Both the air heat exchanger 5 and the dehumidifier 6 are located in the dehumidification room 4. The second heat exchange conveying pipeline 10 is detachably connected to the oil inlet of the air heat exchanger 5, and the oil outlet of the air heat exchanger 5 is detachably connected to the second oil outlet pipeline 12, which is connected to the oil inlet of the oil filter 3. Pipeline valves 13 are installed on the first branch pipeline 7, the second branch pipeline 8, the first heat exchange conveying pipeline 9, the second heat exchange conveying pipeline 10, the first oil outlet pipeline 11, and the second oil outlet pipeline 12. A temperature control valve 14 is installed on the second branch pipeline 8.

[0018] In use, the finished honeycomb cardboard is placed in the dehumidification room 4 for storage. When the temperature of the lubricating oil delivered from the air compressor lubricating oil output line 1 is low, the lubricating oil can be directly delivered to the oil filter 3 via the first branch line 7. After being filtered by the oil filter 3, the lubricating oil is then returned to the air compressor. When the temperature of the lubricating oil delivered from the air compressor lubricating oil output line 1 is high and the dehumidification room 4 is not needed, the lubricating oil can be delivered to the oil cooler 2 via the second branch line 8 and the first heat exchange conveying line 9. After being cooled by the oil cooler 2, the cold lubricating oil is filtered by the oil filter 3 and then returned to the air compressor. When dehumidification chamber 4 requires heating and dehumidification, hot lubricating oil can be transported to air heat exchanger 5 via the second branch pipe 8 and the second heat exchange conveying pipe 10. The air heat exchanger 5 transfers the heat from the hot lubricating oil to the air in dehumidification chamber 4, and then the cooled lubricating oil is transported to oil filter 3. After filtration, it is returned to the air compressor. The heated air in dehumidification chamber 4 effectively evaporates the moisture from the honeycomb cardboard. The dehumidifier 6 then condenses and discharges the moisture from the air in dehumidification chamber 4, effectively reducing the humidity inside the chamber and ensuring the storage quality of the honeycomb cardboard. This effectively utilizes the waste heat of the air compressor's lubricating oil system to heat and dehumidify the dehumidification chamber 4 storing the honeycomb cardboard, resulting in energy savings, environmental protection, improved product quality, and greater practicality. The air compressor lubricating oil output pipe 1, oil cooler 2, oil filter 3, dehumidifier 6, pipe valve 13, and temperature control valve 14 can all use existing technologies. Specifically, the existing conventional DP1380A dehumidifier can be used.

[0019] In this embodiment, the air heat exchanger 5 includes a base 15. A hollow oil inlet main plate 16 is fixedly provided on the top of the base 15. A plurality of evenly distributed and hollow oil inlet sub-plates 17 are fixedly connected to the top of the oil inlet main plate 16. A plurality of evenly distributed spiral heat dissipation coils 18 are fixedly connected to the top of the oil inlet sub-plates 17. Heat dissipation fins 19 are evenly distributed on the outer wall of the heat dissipation coils 18. The top of the heat dissipation coils 18 on the same oil inlet sub-plate 17 is fixedly connected to the same hollow oil outlet sub-plate 20. The top of the oil outlet sub-plate 20 is fixedly connected to the same hollow oil outlet main plate 21. The oil inlet of the air heat exchanger 5 is located on one side of the oil inlet tray 16, and the oil outlet is located on the side of the oil outlet tray 21 away from the oil inlet. The tail end of the second heat exchange conveying pipeline 10 is fixedly connected to the first hose 22. The first hose 22 is connected to the oil inlet of the air heat exchanger 5 through the first quick connector 23. The head end of the second oil outlet pipeline 12 is fixedly connected to the second hose 24. The second hose 24 is connected to the oil outlet of the air heat exchanger 5 through the second quick connector 25.

[0020] When the air heat exchanger 5 is working, the hot lubricating oil delivered through the second heat exchange conveying pipeline 11 is first delivered to the main oil inlet tray 16, then distributed to various oil inlet sub-traces 17, and further distributed to various heat dissipation coils 18, flowing from bottom to top. This effectively prolongs the residence time of the lubricating oil in the air heat exchanger 5. Furthermore, through the cooperation of multiple heat dissipation coils 18 and the multiple heat dissipation fins 19 on each heat dissipation coil 18, the heat in the lubricating oil can be effectively dissipated into the air inside the dehumidification chamber 4, resulting in better heat transfer and more effective heating of the air inside the dehumidification chamber 4, making it more practical. Next, the lubricating oil after heat exchange first collects in the oil outlet sub-traces 20, then in the main oil outlet tray 21, and then is delivered to the oil filter 3 for filtration via the second oil outlet pipeline 12. Furthermore, when the air heat exchanger 5 malfunctions and needs replacement, the connection between the first quick connector 23 and the oil inlet of the air heat exchanger 5 can be quickly disconnected, and the connection between the second quick connector 24 and the oil outlet of the air heat exchanger 5 can be quickly disconnected, thus allowing the air heat exchanger 5 to be replaced. When replacing, after obtaining the new air heat exchanger 5, the oil inlet and outlet of the air heat exchanger 5 can be connected to the corresponding hoses using the first quick connector 23 and the second quick connector 25, allowing for continued use. This facilitates convenient disassembly and replacement of the air heat exchanger 5, making the overall use of the device more flexible and convenient.

[0021] In this embodiment, hydraulic cylinders 26 are vertically fixed at each of the four corners of the base 15. Inverted U-shaped support legs 27 are fixedly sleeved on the outer side of the cylinder body of each hydraulic cylinder 26. The piston rod of the hydraulic cylinder 26 faces downwards, and casters 28 are mounted on its bottom end. When the piston rod of the hydraulic cylinder 26 is in the retracted state, the bottom end of the caster 28 is higher than the bottom end of the support leg 27. This allows the hydraulic cylinder 26 to be operated to extend its piston rod after disconnecting the connection between the air heat exchanger 5 and the corresponding hose when the air heat exchanger 5 needs to be replaced. This extends the piston rod, causing the casters 28 to move downwards until they are placed on the ground and the support legs 27 are lifted. The four sets of casters 28 then work together to move the entire air heat exchanger 5 flexibly, making it easier to remove the old air heat exchanger 5. Simultaneously, it also facilitates the movement of the new air heat exchanger 5 into the dehumidification room 4. Once in position, the piston rod of the corresponding hydraulic cylinder 26 retracts, causing the caster 28 to move upward and suspend in the air, and placing the outrigger 27 on the ground. This supports and fixes the air heat exchanger 5, facilitating subsequent use and making the overall use of the device more flexible and convenient.

[0022] In this embodiment, the dehumidification room 4 is constructed of rock wool panels for heat preservation. A sealed door 29 is provided on one side of the dehumidification room 4 for easy access. The specific opening and closing method and structure can be achieved using existing technology and will not be detailed here.

[0023] In this embodiment, the temperature control valve 14 consists of a 75-degree Celsius temperature control valve 30 and a 100-degree Celsius temperature control valve 31 connected in series, so as to flexibly adjust its delivery flow rate according to the actual temperature of the lubricating oil.

[0024] In this embodiment, a booster pump 32 is provided on the second heat exchange delivery pipeline 10 to pressurize and ensure that the hot lubricating oil flows smoothly through the air heat exchanger 5.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
