摘要
根据城市生活垃圾的组成,配制模拟城市生活垃圾,通过添加有机氯化物(PVC)和无机氯化物(NaCl)调节模拟垃圾的含氯量,并在实验室条件下用管式炉对模拟垃圾的焚烧产物HCl的释放特性进行研究。同时,采用傅里叶变换红外光谱烟气分析仪对垃圾焚烧产生的HCl气体进行实时检测。结果表明,相对于焚烧添加NaCl的模拟垃圾而言,添加PVC的模拟垃圾焚烧产生的HCl体积分数较高。随着含氯量的增加,含PVC的模拟垃圾焚烧产生的HCl体积分数增加,而含NaCl的模拟垃圾产生的HCl则变化不大。程序升温时,焚烧添加PVC的模拟垃圾时发现在250℃开始释放出HCl气体,在300℃左右释放出的体积分数最大,然后缓慢减弱并延续到600℃左右。焚烧添加NaCl的模拟垃圾时,发现当温度大于900℃时检测到一定体积分数的HCl气体。
According to the composition of municipal solid waste, simulated municipal solid waste （SMSW） was prepared and used in the tests. The chlorine content of SMSW was regulated by adding different content of organic chloride（PVC） and inorganic chloride（NaCl）, and a lab-scale tube furnace was applied to investigate the emission characteristics of HCl during SMSW incineration. The gaseous HCl emission was measured by Fourier transform infrared spectrometer（FTIR）. Results show that compared to the combustion of SMSW with NaCl, the HCl concentration is relatively higher in the incineration of SMSW with PVC. With the chlorine content increasing, the HCl absorption from SMSW combustion with PVC quickly increases. However, there is no significant change in the case of SMSW incineration with NaCl. The HCl release beginning temperature in the incineration of SMSW with PVC is around 250 ℃ and the maximum concentration value of HCl occurs at 300℃ . Gaseous HCl emission can be detected above 900℃ in SMSW incineration with NaCl.
