为了探索节能减排的烤烟烘烤模式,2009-2010年,在贵州省黔西南州兴义市修建了2栋热泵太阳能密集烤房,并进行了烤烟烘烤节能试验。每栋烤房可装鲜烟叶3 500 kg,烘烤烟叶质量与普通密集烤房相当。使用热泵烘烤烟叶(CK),每千克干烟叶耗电3.08 kW.h,能耗成本为1.40元。使用热泵并利用太阳能作为辅助能源,则每千克干烟叶能耗成本较对照节省24.29%。使用热泵供热,并利用太阳能,同时将排湿热循环利用,则每千克干烟叶能耗成本为0.94元,与CK相比,能耗成本节省达32.86%。结果表明,热泵型太阳能密集烤房烘烤烟叶质量好,节能效果显著。
In order to explore the flue-cured tobacco baking mode of energy-saving and emission reduction, from 2009 to 2010, two heat pump solar energy curing barns were built in Xingyi, Guizhou Province, and energy saving experiments were conducted. Each barn can be loaded with fresh tobacco 3 500 kg, baked tobacco quality and general intensive barn quite. Using a heat pump to cook tobacco leaves (CK), the energy consumption per kg of dried tobacco leaves is 3.08 kW.h, resulting in an energy cost of 1.40 RMB. Using heat pumps and using solar energy as an auxiliary energy source, the energy cost per kilogram of dried tobacco leaves is 24.29% less than the control. The use of heat pump heating, and the use of solar energy, while the wet heat recycling, the energy consumption per kilogram of dry tobacco costs 0.94 yuan, compared with the CK, the energy cost savings of up to 32.86%. The results show that heat pump type solar energy intensive barn baking tobacco quality, energy saving effect is remarkable.
