【摘要】：利用熱重-紅外聯(lián)用分析儀(TG-FTIR)研究了垃圾衍生燃料(RDF)、污泥及混合熱解的反應(yīng)動力學(xué)和氣體產(chǎn)物析出特性。研究結(jié)果表明,RDF與污泥混合熱解過程存在協(xié)同作用。當(dāng)污泥的摻混比例為50%時,整個熱解過程表現(xiàn)為促進(jìn)作用,且在500~1000℃溫度段的促進(jìn)效果最為明顯。采用Coats-Redfern法對熱解過程進(jìn)行動力學(xué)分析發(fā)現(xiàn),RDF與污泥混合熱解反應(yīng)在低溫段(240~380℃)和高溫段(670~740℃)符合2級反應(yīng)規(guī)律,而在中溫段(430~540℃)符合1級反應(yīng)規(guī)律;相對于RDF單獨(dú)熱解,RDF摻混污泥共熱解的活化能明顯降低。FTIR分析發(fā)現(xiàn),RDF摻混污泥共熱解對CO_2和CO的析出影響不大,對CH_4的產(chǎn)生有明顯促進(jìn)作用。同時,共熱解也導(dǎo)致HCl、NH_3和HCN等污染物析出增加。本研究結(jié)果可為RDF和污泥共熱解工藝的開發(fā)與設(shè)計(jì)提供數(shù)據(jù)支撐。
[Abstract]:TG-FTIRs were used to study the reaction kinetics and gas product precipitation characteristics of waste derived fuel RDF, sludge and mixed pyrolysis. The results showed that there was a synergistic effect between RDF and sludge in the process of pyrolysis. When the mixing ratio of sludge is 50, The whole process of pyrolysis takes on a promotive effect, The kinetic analysis of the pyrolysis process with Coats-Redfern method showed that the mixed pyrolysis reaction between RDF and sludge at low temperature stage (240 鈩，
