摘要
在小型管式炉中进行了纸厂含氯废弃塑料焚烧过程中HCl析出特性实验,研究了温度、粒径、停留时间对HCl析出的影响;同时借助热重-傅里叶红外光谱联用技术(TG-FTIR)研究了HCl在焚烧过程中的析出规律.结果发现,燃烧过程中Cl→HCl的转化率随温度、粒径和停留时间的增大而显著增加;TG-FTIR结果表明,HCl在200℃左右开始析出,300℃左右达到最大值,400℃后析出峰逐渐消失.XRD结果可知,残余氯以无机氯盐的形式存在灰样中.
Plastic waste from a paper mill with chlorine incineration was investigated in a small tube furnace. Factors such as temperature, particle size, and detention time in the process of waste plastic incineration were considered. Thermogravimetric analysis （TG） coupled with Fourier transfer infrared spectroscopy was used to analyze emission characters of HC1. Results show that conversion rate of C1 to HC1 increased with the temperature, particle size and detention time; TG-FTIR shows HC1 was generated at about 200℃, reached maximum at about 300℃and declined gradually after 400℃. XRD indicates that residual chlorine resided in the ash in the form of inorganic chloride.
