Operation principle:
The utility model can be by gravity-flow ventilation and two kinds of mechanism operations of forced ventilation, and under intensive baking condition, gravity-flow ventilation performance leading role, the design of cold and hot integrated hydrofuge sleeve 4, utilize hot flue gas to humid air heat, mixing and injection, obviously strengthened the ventilating capability of tobacco flue-curing house, can make under the intensive baking operating mode hydrofuge still smooth and easy; The high-temperature flue gas that burner hearth 18 fuel combustion produce is by having the high-performance heat exchanger 36 of three layers of flue and flue gas header, can heat by the air of hot blast chamber and provide a large amount of hot blasts for baking tobacco leaves, utilize asbestos shingle dividing plate 28 simultaneously, formed half isolated hot blast chamber, not only improve air velocity, enhanced heat exchange, and can keep an amount of interlayer crossflow, adjust the temperature difference between canopy automatically; After setting up poly-wetland ditch 41, combine, not only solved the difficult problem that end canopy tobacco leaf is difficult for drying because of the air humidity height, and strengthened poly-wet ability, guarantee hydrofuge equilibrium everywhere in the tobacco flue-curing house with moisture exhausting port 38 and raising end canopy; The bypass flue 39 of design can be where necessary, make an amount of high-temperature flue gas directly enter chimney and improve ventilating capability, guarantees the still powerful and regulation and control of low thermophase ventilating capability freely; Wind-supplying mouth 9 can be regulated its aperture size by auto-controller, replenishes air in time, in right amount, satisfies the requirement of humiture in the tobacco flue-curing house; Give full play to the free convection potentiality, utilize heating, mixing and the ejector action of flue gas, increase the ventilating capability of humid air rising power and tobacco flue-curing house, strengthen natural convection air, reduce flowing resistance, keep an amount of interlayer air convection current, reduce humiture difference up and down, improve heating and heat exchange efficiency, therefore, this gravity-flow ventilation tobacco flue-curing house obviously is better than conventional gravity-flow ventilation tobacco flue-curing house; Two single-phase electricity small-power ventilating fans 26 are set in addition, can send hot blast to hanging the smoke-box headroom, in order to increase the malleation that air-flow descends, aspirate the hot blast of hot blast chamber simultaneously, reach the effect of strengthening flow circulation and heat exchange, simultaneously, thermal current passes the endless form of tobacco leaf layer from top to bottom, can make that the plane temperature is even, heat and moisture preserving is good, improve baking quality of tobacco; Supporting auto-controller, both can set process conditions such as concrete temperature, humidity, time, can set baking process (being the baking process curve) again, therefore can realize baking process correct automatic adjustment and control in time, crucial booster action be arranged guaranteeing baking quality.
The utility model in use, if move with natural ventilation system, the cigarette pole of compiling full cigarette that evenly distributes is in advance hung up on several stringers 25, close the door 15 of tobacco flue-curing house, coal is lit a fire vigorous to burning in burner hearth 18, flowed through bottom-up the flowing in hot flue gas heating back of heat exchanger 36 of the half indoor air of isolated hot blast, enter cigarette-filling house then, after hot-air from up to down toasts many canopies tobacco leaf, the part humid air is got back to the hot blast chamber by the return air inlet of bottom and is mended and reheated rising after the dry air of going into converges, and enters cigarette-filling house once more and removes to heat wet tobacco leaf.On auto-controller, can set concrete temperature, humidity, time etc. by the baking schedule requirement.When just having begun to hang down thermophase,, can make an amount of high-temperature flue gas directly enter chimney 3 by operation through bypass flue 39 in order to improve ventilating capability.Change according to the humiture in the cigarette-filling house, regulate the aperture size and the open and close time of wind-supplying mouth 9 by auto-controller.In the overall process of baking tobacco leaves, the action of auto-controlling apparatus can be carried out by the baking schedule of setting, until whole tobacco leaf dryings are reached quality requirement.
If move in the forced ventilation mode, the basic operation method is identical during with the gravity-flow ventilation operating mode, only need utilize the operation of two ventilating fans 26, optimizes intensive baking operating mode, reaches the effect of strengthening flow circulation and heat exchange, and then the shortening stoving time; Simultaneously can be according to the demand of baking process to the barn humiture, start and stop by controller control heating furnace air blast, by adjusting the Coal-fired capacity and the combustion position of heating furnace, guarantee that heating demand satisfies the demand of flue-cured tobacco, provide advantage for guaranteeing baking quality of tobacco.
