摘　　要：针对固体废物处理过程中的能量回收问题,采用管式反应器,对生活垃圾、工业废料等固体废物进行热解实验,研究温度、停留时间、进料速率等工艺参数对热解产物分布及能量回收效率的影响。实验结果表明,热解温度是影响产物分布的关键因素在550℃时热解气体产率最高,可达45%,热解油最佳产率为28%,出现在500℃工况下。通过能量平衡分析可知,固体废物热解过程的总能量回收效率可达65%,其中气体产物和液体燃料的能量转化效率分别为38%和27%。There are problems in energy recovery in the process of solid waste treatment.The study conducts the pyrolysis experiment of solid waste,such as domestic waste and industrial waste,etc.,and analyzes the effects of temperature,residence time and feed rate on the distribution of pyrolysis products and energy recovery efficiency through tubular reactor.The experiment shows that the pyrolysis temperature is the key influencing factor of the product distribution.The pyrolysis gas yield reaches 45%at 550℃,and the pyrolysis oil yield reaches 28%at 500℃.According to the energy balance analysis,the total energy recovery efficiency of solid waste pyrolysis can reach 65%,and the energy conversion efficiency of gas products and liquid fuels is 38%and 27%,respectively.
