[0002] Drying refers to the process of removing solvents and retaining solid content in some way. It usually refers to the process of introducing hot air to evaporate and take away the moisture in the material. According to the three ways of heat transfer, heat conduction, heat convection, and heat radiation, there are also three corresponding ways of drying: drum drying, hot air drying, and far-infrared drying. There are many ways of drying, including heat pump, airflow drying, induction drying, and sol drying. Among them, airflow drying, airflow drying technology uses the principle of forced ventilation and circulating airflow. The indoor air is heated by a heater and sent into the drying room, and then discharged after the dried items, forming a circulating drying process. This drying effect is better and can be used for drying in many fields.

[0003] In the prior art, a Chinese patent with publication number CN213090308U discloses a horizontal airflow type heat pump drying device, in which fresh items to be dried are placed on a drying tray, the drying tray is then clamped on a bracket, and the door is closed, and the first circulation fan and the second circulation fan, the heat pump heat exchange unit, and the heat pump drying unit are started in sequence. The items enter the preheating stage, and the temperature sensor monitors the temperature in the dryer. When the preheating temperature reaches the drying temperature, the constant temperature dehumidification stage is entered, that is, the dehumidification fan is started. At this time, the temperature is controlled within a reasonable range, and the humidity sensor is used to monitor the humidity to determine the conditions for the conversion of each sub-stage. When the humidity reaches the final result at a certain temperature, the next sub-condition is entered. In summary, the utility model is compact and does not take up space, and the horizontal airflow can evenly dry the items to be dried, and at the same time has the function of dehumidification, and is easy to operate.

[0008] Furthermore, the waste heat recovery device includes a conformable pipeline, a circulation pump and a liquid storage tank. The conformable pipeline is sleeved on multiple groups of air ducts. The circulation pump is fixed on one side of a group of air ducts and connected to the conformable pipeline. There is a pipe joint between the liquid storage tank and the air duct, and the liquid storage tank is connected to the conformable pipeline.
