摘要
农业纤维物料在二次压缩过程中的比能耗受物料本身特性和压缩条件的影响.为探究不同因素对农业纤维物料二次压缩比能耗的影响,对秸秆捆在不同的压缩方向、初始压缩密度和含水率条件下进行压缩试验和分析.结果表明:不同压缩方向对压缩比能耗没有显著影响;对应相同的压缩量,存在最适宜初始压缩密度使得压缩比能耗达到最小值;当压缩密度小于500 kg.m-3时,压缩比能耗和压缩密度具有正比例关系;在安全含水率范围内,压缩比能耗随含水率的增大而减小.
The specific energy consumption of recompression for fibrous agricultural materials was deter- mined by material characteristics and compression conditions. In order to investigate the effects of diffe rent factors on the specific energy of recompression, compression tests and analysis were conducted with different compression directions, initial densities and moisture contents. The results show that compres- sion direction has slight effect on the specific energy. The minimum specific energy consumption can be obtained with an optimum initial density value for the same compressed volume. When compressed density is lower than 500 kg · m-3, the specific energy consumption has a positive relationship with compressed density. The specific energy is decreased with the increasing of moisture content in safe storage range.
