农林固体有机废弃物是很重要的生物质资源,其质地松散,压缩可使分子间致密紧凑,节约空间,便于储运和加工利用.因此,有关农林固体有机废弃物压缩成型技术与设备等方面的研究一直备受人们关注.简要介绍了农林固体有机废弃物资源化利用类型及压缩成型研究现状,对压缩成型原理及相关影响因素进行了分析,针对使用比较广泛的3种成型工艺即常温压缩成型、热压成型、炭化成型分别进行了介绍,分析了不同类型压缩成型设备的差异,总结发现有关农林固体有机废弃物收集、成型前处理、压缩成型、后续深加工以及应用专属性评价等全过程管理与技术体系还不完善的地方,展望了今后压缩成型技术的发展趋势.
The agricultural and forestry solid organic wastes (AFSOWs) are the important biomass resources. Densification forming can make the loose AFSOWs into the formed and compacted biomass, which is helpful for their storage, transport, post-processing and utilization. Thus, the research on the densification forming technology and equipment has attracted much attention for processing the AFSOWs in recent decades. The research status of different densification forming technologies was reviewed. The principles and techniques of the densification forming were discussed. The densification forming technology at room temperature, hot-press forming and carbonization forming were widely used and introduced respectively. The differences among various types of the densification forming equipment were analyzed. The results showed that the whole process for the utilization of the AFSOWs included the collection, pre- forming treatment, the densification forming, post-process and evaluation for special application. It could be seen that the system of management and technology for the whole process needed to be improved. The prospects for the development of the densification forminl~ technology for treatment of the AFSOWs were provided.
