Abstract
Description
Technical Field
[0001] This utility model relates to the field of dehumidification equipment, specifically a dehumidification heat recovery device. Background Technology
[0002] When drying crops, dehumidification equipment is needed to remove the moisture generated during the drying process. Fresh air needs to be introduced during the drying process, but the introduction of fresh air will lower the drying temperature. More heat is needed to heat the fresh air to the drying temperature. Existing dehumidification equipment has a single function, which can only remove moisture and cannot utilize the waste heat from the dehumidification process, resulting in energy waste. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dehumidification and heat recovery device to address the deficiencies of the prior art.
[0004] The purpose of this utility model is achieved through the following technical solution: a dehumidification and heat recovery device, including a heat exchange box, a heat exchange core is provided in the inner cavity of the heat exchange box, a dehumidification fan is provided at the top of the heat exchange box, a dehumidification air inlet hood is connected to the bottom of the heat exchange box, the heat exchange core is located between the dehumidification air inlet hood and the dehumidification fan, hot air pipes are connected to both sides of the heat exchange box, the hot air pipes communicate with the inner cavity of the heat exchange box, and a circulating fan is provided on the hot air pipes.
[0005] Furthermore, the heat exchange core includes rectangular mounting frames and aluminum fins. Multiple rectangular mounting frames are spaced apart along the height direction of the heat exchange box. Several aluminum fins are stacked within the rectangular mounting frames, and the aluminum fins are fixed together by the multiple rectangular mounting frames.
[0006] Furthermore, an installation groove is provided on one side of the heat exchange box, the installation groove is connected to the inner cavity of the heat exchange box, and the heat exchange core is assembled in the heat exchange box through the installation groove.
[0007] Furthermore, a baffle is rotatably provided on the end face of the rectangular mounting frame near the mounting groove. The length of the baffle is greater than the width of the mounting groove, the width of the baffle is less than the width of the mounting groove, and the length of the baffle is less than the length of the mounting groove.
[0008] Furthermore, a rotating shaft is fixed to one end of the baffle near the rectangular mounting frame, and a torsion spring is fitted on the rotating shaft. The rectangular mounting frame has a shaft hole, and the torsion spring is assembled in the shaft hole. When the torsion spring is in its normal state, the baffle is horizontal and abuts against the inner wall of the heat exchange box.
[0009] The beneficial effects of this utility model are:
[0010] The hot steam generated during drying enters the heat exchange box through the dehumidification air inlet hood. It absorbs the heat of the dehumidified gas through the heat exchange core and then releases the heat from the hot air pipe. The heat is then used to heat the fresh air before it is introduced into the drying equipment. This process utilizes the residual heat from the dehumidification for heat exchange, which can raise the temperature of the fresh air by 5-10°C, thus making full use of the heat from the dehumidification.

[0016] Example 1
[0017] A dehumidification heat recovery device includes a heat exchange box 1, an inner cavity of which is provided with a heat exchange core 2, a dehumidification fan 3 is provided on the top of the heat exchange box 1, and a dehumidification air inlet hood 4 is connected to the bottom of the heat exchange box 1. The heat exchange core 2 is located between the dehumidification air inlet hood 4 and the dehumidification fan 3. Hot air pipes 5 are connected to both sides of the heat exchange box 1, and the hot air pipes 5 are connected to the inner cavity of the heat exchange box 1. A circulating fan 6 is provided on the hot air pipes 5. The hot steam generated during drying enters the heat exchange box 1 through the dehumidification air inlet hood 4, absorbs the heat of the dehumidified gas through the heat exchange core 2, and then releases the heat from the hot air pipes 5. The hot air pipes 5 are connected to the drying equipment, and the heated fresh air is introduced into the drying equipment through the circulating fan 6, thereby utilizing the waste heat of dehumidification for heat exchange, which can raise the temperature of the fresh air by 5-10°C, so that the dehumidification heat is fully utilized.
[0018] Example 2
[0019] Based on Embodiment 1, the heat exchange core 2 includes a rectangular mounting frame 7 and aluminum fins 8. Multiple rectangular mounting frames 7 are spaced apart along the height direction of the heat exchange box 1. Several aluminum fins 8 are stacked inside the rectangular mounting frames 7 and fixed together by multiple rectangular mounting frames 7. A mounting groove 9 is opened on one side of the heat exchange box 1, which connects to the inner cavity of the heat exchange box 1. The heat exchange core 2 is assembled in the heat exchange box 1 through the mounting groove 9. Hot steam enters the heat exchange box 1 and contacts the surface of the aluminum fins 8. Heat energy is transferred through heat conduction. During this process, the temperature of the hot steam gradually decreases, while the heat transfer surface inside the aluminum fins 8 increases. Fresh air enters the heat exchange box 1 through the mounting groove 9 and exchanges heat with the aluminum fins 8, causing the fresh air to absorb heat and become hot air. Finally, it is discharged from the hot air pipe 5. Multiple aluminum fins 8 are gathered together by the rectangular mounting frames 7, which facilitates the installation and disassembly of the heat exchange core 2.
[0020] Example 3
[0021] Based on Embodiment 2, a baffle 10 is rotatably mounted on the end face of the rectangular mounting frame 7 near the mounting groove 9. The length of the baffle 10 is greater than the width of the mounting groove 9, the width of the baffle 10 is less than the width of the mounting groove 9, and the length of the baffle 10 is less than the length of the mounting groove 9. A rotating shaft 11 is fixed to one end of the baffle 10 near the rectangular mounting frame 7, and a torsion spring 12 is fitted on the rotating shaft 11. A shaft hole 13 is provided on the rectangular mounting frame 7, and the torsion spring 12 is assembled in the shaft hole 13. When the torsion spring 12 is in its normal state, the baffle 10 is horizontal and abuts against the inner wall of the heat exchange box 1. Rotating the baffle 10 to a vertical state makes the baffle... Plate 10 can pass smoothly through mounting slot 9, and then rectangular mounting frame 7 is inserted into the inner cavity of heat exchange box 1 through mounting slot 9. When heat exchange core 2 is inserted into place, baffle 10 moves into heat exchange box 1. Baffle 10 is released, and under the action of torsion spring 12, baffle 10 is deflected to a horizontal state. At this time, baffle 10 is pressed against the inner wall of heat exchange box 1, and baffle 10 cannot be moved out of mounting slot 9, thus stably installing heat exchange core 2 in heat exchange box 1. When disassembling, simply deflect baffle 10 to a vertical state and pull out heat exchange core 2. The operation is simple and quick, and it is convenient to replace and maintain heat exchange core 2 later.
