汚染防止にも有益である。According to the first aspect of the present invention, there is provided a heat recovery apparatus for a Burley leaf tobacco drying room according to the first aspect of the present invention. It is conveyed downward and exchanges heat with the circulating air of the compact dryer via a heat pipe type heat exchanger. In the upper part of the standard drying room, the room air is heated to 50 ° C to 70 ° C by the radiant heat of the sun, so this high-temperature air is conveyed downward by the circulator and the duct, and the hot air is discharged from the drying room of the compact dryer. By exchanging heat with the circulating air returned to the furnace of the generator unit, the temperature of the circulating air returning to the furnace can be raised, and the amount of combustion in the burner can be reduced accordingly, thus reducing the amount of fuel oil. Can be done. In addition, since the amount of combustion is reduced, the emission of CO 2 is reduced, which is also beneficial for preventing environmental pollution.

Is higher, so that the circulating air of the compact dryer, which exchanges heat therewith, rises to a higher temperature than in the first embodiment. Therefore, the fuel amount can be further reduced and CO 2

る。Further, according to the third aspect of the present invention, if the temperature of the intake air of the circulator decreases during the operation after sunset or if the indoor air temperature of the upper part of the standard drying room does not become very high in rainy weather, By detecting the temperature, the amount of air conveyed downward by the circulator can be reduced to a certain amount. Therefore, only heat from the combustion exhaust gas is used for heat exchange with the circulating air of the compact dryer, and the temperature of the combustion exhaust gas is reduced by air that is not so hot carried by the circulator, and the heat exchange efficiency is reduced. Never do. In addition, even if the room air temperature in the upper part of the standard drying room is low, blowing a constant air volume with the circulator prevents the combustion exhaust gas from being drawn upward and from coming into contact with the heat pipe type heat exchanger. Needed to do so.

Part of the warm air supplied to the hot air generator unit b is returned to the warm air generator unit b again as circulating air through the suspended leaf tobacco D, and the heat pipe type heat exchange is performed on the circulation side of the warm air generator unit b. Circulating air in the indoor duct
Since the temperature is slightly lower than when blown up from 12, the heat pipe type heat exchanger 15 generates a temperature difference between the circulation side of the hot air generator unit b and the duct 2 side,
The enclosed working fluid boils due to the heat applied to the side and the steam flows from the duct 2 side to the circulation side of the hot air generator unit b, whereby the hot air generator unit b
Heat is transferred to the circulation side of the hot air generator unit b
Is condensed on the circulation side of, and heat of condensation is released. Therefore, the circulating air returned to the hot air generator unit b is heated to a high temperature, and the combustion amount of the burner 4 is controlled to be small accordingly.

なり、その分バーナー４の燃焼量は小さく制御される。At night or when the indoor air temperature in the upper layer of the standard drying room A is lower than the set temperature of 45 ° C. to 50 ° C. or more due to rainy weather, the circulator 1 is kept ON, but at the same time, the damper 3 Turn on the duct 2
To reduce the amount of air to be conveyed downward to a predetermined amount. As a result, the amount of air flowing through the duct 2 is reduced, and only the combustion exhaust gas is used for heat exchange. Further, the combustion exhaust gas is hardly cooled by the non-high-temperature wind flowing through the duct 2. Therefore, the heat exchange efficiency hardly decreases. Therefore, even in this case, the temperature of the circulating air returned to the hot air generator unit b becomes high due to heat exchange, and the combustion amount of the burner 4 is controlled to be small accordingly.
