【摘要】：生活垃圾熱解技術(shù)具有巨大的應(yīng)用前景,其熱解可以產(chǎn)生高附加值產(chǎn)物熱解油、熱解氣和垃圾炭。垃圾炭的性質(zhì)決定了其用途。該文研究垃圾炭的粒度、堆密度、實(shí)密度、熱穩(wěn)定性、反應(yīng)活性、膠質(zhì)層厚度等性質(zhì),為垃圾炭氣化工藝提供理論支持。實(shí)驗(yàn)結(jié)果表明:垃圾炭硬度較低,破碎時粉化率高、熱穩(wěn)定性較差;垃圾炭的CO_2反應(yīng)活性較差,950℃最高時僅有81.5%,達(dá)不到流化床氣化爐的要求;垃圾炭的著火溫度較高為399℃,對流化床氣化爐點(diǎn)火開車會造成一定影響;垃圾炭灰熔點(diǎn)ST低于1 150℃,容易出現(xiàn)氣化灰渣高溫下熔融現(xiàn)象,破壞流化床氣化爐的正常操作。
[Abstract]:The pyrolysis technology of domestic waste has a great application prospect, which can produce high value-added product pyrolysis oil, pyrolysis gas and waste carbon. The nature of waste carbon determines its use. In this paper, the particle size, bulk density, real density, thermal stability, reaction activity and the thickness of colloidal layer of carbon are studied, which provide theoretical support for the gasification process of waste carbon. The experimental results show that the carbon has low hardness, high pulverization rate and poor thermal stability during crushing, the CO_2 reaction activity of waste carbon is poor at 950C and only 81.5, which can not meet the requirements of fluidized bed gasifier, and the ignition temperature of MSW carbon is 399 鈩，
