Description

Technical Field

[0001] The utility model belongs to the field of tobacco production equipment, and specifically relates to a connected tobacco leaf curing room capable of sharing waste heat. Background Art

[0002] The flue-cured tobacco house is a special house for the primary processing of mature flue-cured tobacco leaves, which mainly includes a tobacco loading room, heating equipment and ventilation system. There are two types of flue-cured tobacco houses: natural ventilation and mechanical ventilation. Natural ventilation includes airflow rising type, airflow falling type and tunnel type. These flue-cured tobacco houses can also be equipped with axial flow fans as auxiliary equipment for dehumidification; mechanical ventilation is a dense flue-cured tobacco house, and ordinary flue-cured tobacco houses with natural ventilation and airflow rising type and dense flue-cured tobacco houses are the most commonly used.

[0003] The utility model with patent number CN201020248823.3 discloses a waste heat sharing device for side-by-side connected intensive tobacco curing barns. This invention adopts a shared main channel to connect two or more side-by-side connected intensive tobacco curing barns. Adjacent or non-adjacent curing barns are in different curing periods. The humid hot gas discharged from the curing barn in the dehumidification period is dehumidified or directly input into another adjacent or non-adjacent curing barn. Therefore, the waste heat discharged in the middle and late stages of the tobacco curing process can be reused, so the thermal energy utilization rate of tobacco curing is high; the gas recovered from the curing barn will carry dust, and repeated circulation in the equipment will affect the service life of the equipment. In addition, the heat of the gas recovered from the curing barn is dissipated, and the drying effect after recycling is limited. Utility Model Content
