密集烤房余热共享在烟叶烘烤中的应用研究
|
摘要
为了对烟叶烘烤过程中排出的烟气余热进行回收利用,提高热能利用率,实现节能减耗、降低成本,在贵州省开阳县宅吉乡潘桐村烤烟烘烤工场对烤房群中的10座烤房进行改进,增设了余热利用装置设施,并与未安装余热回收装置的烤房进行效果对比测试。结果表明,烤房群余热利用可有效地减少燃料用量,平均1 kg干烟叶耗煤1.09 kg,比对照烤房节约0.305 kg,节煤率为21.86%;平均1 kg干烟叶省电0.165 kW·h,省电率为18.44%,节约率达20.94%;每炕次可节约烘烤成本160元。烤后烟叶均价、等级结构较对照烤房略有提高,此外,该余热回收装置有利于烟叶变黄、干燥、回潮,具有较好的推广应用前景。
In order to recycle and re-used waste heat during curing stage, which could achieve the purpose of energy-saving and reduce the cost of baking, ten barn building were improved at Pantong village, Zhaiji town, Kaiyang county of Guizhou province. The waste heat recycling installation of flue gas in tobacco bulk barn was designed and a contrast experiment was carried out for the baking tobacco leaves between the improved bulk curing barn and the conventional bulk curing barn. The results showed that, the improved bulk curing barn had obvious coal-saving effects of fuel consumption, its average coal consumption for 1 kg dry tobacco leaves was 1.09 kg, being 0.305 kg and 21.86% less than the conventional bulk curing barn.The improved bulk curing barn also could save the cost by 0.4 CNY each kg dry tobacco leaves, average power saving of0.165 kW·h, the power saving rate of 18.44%, and its cost-saving rate was 20.94%. In total, it could save the cost of 160 CNY in baking every times. The appearance quality, grade structure and average price of flue-cured tobacco leaves of the improved bulk curing barn were slightly improved than those of control-cured barn. In addition,the waste heat recovery device was conducive to yellowing of tobacco leaves dry, resurgence. This recycling installation has a good promoting efficient.
