Description

Technical Field

[0001] The utility model relates to the field of tobacco production equipment, in particular to a condensed water recovery device for a heat pump drying room. Background Art

[0002] With the continuous development of the tobacco industry, the demand for energy conservation and environmental protection in tobacco processing is becoming increasingly stringent. Heat pump curing barns, as a key energy-saving technology in tobacco curing, are increasingly being used. However, during operation, heat pump curing barns generate a large amount of condensate due to dehydration of tobacco leaves and dehumidification of the curing barns. This condensate is typically discharged directly, resulting in a certain degree of water waste.

[0003] Traditional tobacco curing typically requires a large amount of fresh water to maintain the moisture content of the leaves after curing. This demand places a strain on local water management, particularly in areas where water resources are relatively scarce. Furthermore, the high volume of water required for leaf rehumidification during curing can negatively impact tobacco quality and yield if this issue is not effectively addressed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a condensate recovery device for a heat pump baking room, which can collect condensate generated during the operation of the heating unit of the heat pump baking room and external rainwater, and send them into a storage pool for storage after purification. Finally, the water taken out from the storage pool can be used for the rehumidification of tobacco leaves in the baking room, which not only achieves the purpose of saving water, but also alleviates the problem of water shortage due to rehumidification of tobacco leaves during baking.
