The utility model discloses an energy-saving combined-connection type flue-curing device with a comprehensive moisture recycling function, which comprises a unit flue-curing barn and a moisture heat exchange device, wherein a moisture outlet of the unit flue-curing barn is connected with the moisture heat exchange device, an inlet of a moisture channel of the moisture heat exchange device is communicated with the moisture outlet of the unit flue-curing barn, the moisture channel of the moisture heat exchange device is internally provided with a dry gas channel, the inlet end of the dry gas channel is communicated with the atmosphere, the outlet end of the dry gas channel is provided with a dry hot gas collecting pipe, and the dry hot gas collecting pipe is communicated with the unit flue-curing barn, the adjacent flue-curing barn or a gas circulation system in the flue-cured tobacco room of the spaced flue-curing barn. According to the baking device, the flue-curing barn is combined with a recycling device through moisture heat exchange, and auxiliary heat energy is supplied for the adjacent or spaced flue-curing barn with alternant processes. Dry hot gas after the heat exchange is taken as an auxiliary heat resource of the flue-cured tobacco room, the temperature of the flue-cured tobacco room is directly improved, the fuel coal consumption of the flue-cured tobacco room is reduced by about 20%, the emission volume of carbon monoxide can be reduced by 70-80%, and simultaneously the environmental pollution caused by the outward emission of damp-heat gas is reduced.
