Description
Technical Field

Background
The tobacco leaf baking is to remove 80-90% of moisture in tobacco leaves, and the tobacco leaf baking in China generally adopts a three-stage baking process which is divided into three stages, namely a yellowing stage, a color fixing stage and a stem drying stage, wherein a complete period is about 6-8 days. The temperature of the chimney flue gas in the yellowing stage is 70-220 ℃, and the moisture discharge amount is large; the chimney smoke temperature (99-220 ℃) in the fixed color period is the highest in moisture discharge amount; the chimney flue gas temperature (99-188 ℃) in the dry rib period is low, and the moisture discharging amount is small. The coal consumption of 1kg of dry tobacco leaves in a bulk curing barn is 1.5-2.0kg, a large amount of energy is consumed in the curing process, and about 1 ton of coal is needed for each curing barn. The heat loss of the damp-discharging hot air flow of the curing barn is about 10-20% of the calorific value of the fire coal, and the heat loss of the flue gas of the chimney is about 15-25% of the calorific value of the fire coal. The sum of the two heat losses reaches 25% -45% of the calorific value of the coal, and the recycling of the moisture-discharging airflow and the chimney flue gas waste heat has obvious energy-saving potential.
The tobacco loading capacity of the bulk curing barn is greatly improved compared with the traditional curing barn, so that 0.5-0.8kg of coal can be saved in the aspect of energy consumption compared with the traditional curing barn for curing each kilogram of tobacco leaves. The bulk curing barn adopts open type moisture removal, on one hand, the waste heat of moisture removal airflow is directly lost, on the other hand, the fragrance components and other gas components which are beneficial to improving the curing quality of tobacco leaves are discharged outside the curing barn along with the moisture removal airflow, so that the curing quality of the tobacco leaves is reduced. The totally-enclosed hot air circulation bulk curing barn can avoid heat loss caused by direct emission of the dehumidifying air flow and quality reduction caused by direct emission of the aroma components, achieves the effects of energy conservation and quality improvement, and has the key technology that water vapor in the dehumidifying air flow is efficiently removed to enable the dehumidifying air flow to be recycled, and solution dehumidification can realize efficient dehumidification according to a physical absorption principle. The solution absorbs moisture, the dehumidification capacity is reduced, the solution needs to be heated, regenerated and restored to the dehumidification capacity, and the heating temperature is 80 ℃ at most. The flue gas temperature of the chimney in the whole baking process is 70-220 ℃, so that the flue gas can be used for regenerating solution and realizing waste heat recycling.
The analysis shows that the problems of energy consumption, flue gas waste heat utilization and recovery and tobacco quality caused by open type moisture removal in the curing process of the intensive examination room are solved, and the method has important practical value and social significance for realizing energy conservation, quality improvement and efficiency improvement.
