摘要：   为研究医疗废物典型组分热解/焚烧过程无机氯的析出特性，检测了不同热解温度、焚烧温度和气流量等工况下无机氯的释放，分析了多种典型组分对输液管无机氯析出特性的作用。结果表明，工况变化对医疗废物无机氯总析出的影响不大，对Cl-Cl2和Cl-HCl转化率的影响相对明显。与单组分输液管相比，输液中加入纤维物质明显地促进Cl2的生成，但对HCl的生成表现出一定的抑制作用；而橡胶的存在对HCl抑制作用最为显著，使Cl-HCl转化率有很大程度地降低。

Abstract:   In order to investigate inorganic chlorine released from the process of medical waste pyrolysis/incineration，a series experiments with different pyrolysis temperature，combustion temperature and gas flow rate were conducted；the effect of other compositions on inorganic chlorine emission from medical tube（PVC）incineration was also studied. Total conversion rate of inorganic chlorine just slightly changes under diferent conditions，but the variation in conversion rate of Cl2 and HCl are comparatively remarkable. Compared to the single PVC incineration，the addition of fiber can obviously promote Cl2 formation，and slightly prevent HCl release. HCl emission is significantly reduced by the presence of rubber，the conversion rate of HCl decreased.
