摘要

为掌握医疗废弃物的热解特性，在管式炉中对医疗废弃物典型有机组分进行热解实验研究，并用在线气体分析仪监测物料主要热解气体成分及其含量的变化，得到了物料产气过程和产气成分随温度的变化规律。研究结果表明，物料特性、热解终温对气体产物的生成过程和分布影响较大。与纤维素类的脱脂棉和竹子相比，聚丙烯的分解反应起始温度明显较高。提高热解温度会提高气体析出峰值和产量，以及热解气中可燃气体的比重。

Abstract

Pyrolysis characteristics of typical organic components of medical waste were studied by using a fixed bed tubular reactor.The composition and volume fraction of pyrolysis gas were measured by on-line gas analyzers.The effect of pyrolysis temperature was also analyzed.The results indicated that the material characteristics and the final pyrolysis temperature had great effects on the release and volume fraction of pyrolysis gas.The results indicated that the absorbent cotton and bamboo had a lower initial temperature than polypropylene when pyrolyzed.The maximum of gas generation rate and the gas yield increased with the pyrolysis temperature

as well as the proportion of the combustible gas in the total gas products.
