摘　　要：在国内外先进微波裂解炉的基础上,设计出一种单位质量反应物微波输出能量暴露可控的裂解装置,随着质量和反应剩余时间的减小自动降低微波功率,保证反应物在整个裂解过程中单位质量微波输出能量暴露不变。减少了传统的微波裂解设备在裂解后期反应物质量变小却在高功率微波辐射下发生的焦化反应,保证反应物裂解在稳定的反应条件下完成,详细介绍了裂解装置结构设计和技术方案,并通过实验进行了测试。Microwave technology has gained tremendous importance in the thermo-chemical treatment of waste materials,including biomass,waste cooking oil,used engine oil,scrap tires,algae and others.The key to the improvement of utilization efficiency is the design of the microwave pyrolysis reactor.The controllable output energy per unit mass of microwave pyrolysis apparatus is designed on the basis of previous studies.To ensure the absorbed energy unchanged in the pyrolysis reaction process,the microwave power is decreased with the reduction of sample weight and reaction time.Compared with the traditional pyrolysis,the coking reaction is effectively inhibited under the irradiation of high power microwave,which ensures the pyrolysis of the samples undertaken under the stable conditions.The structural design and technical program for pyrolysis reactor is highlighted in this study.The related experiments are performed as well.
