发布时间：2018-12-13 13:04
【摘要】：工业化应用最为成熟的煤炭热解技术为内热式热解技术。目前内热式热解炉工业化装置规模最大,总装置规模已超过2亿t(以入炉煤量计),该技术存在着控制技术落后、煤气质量差、能量综合利用低和环境污染严重等问题。文中分析了目前内热式热解炉的技术进展和存在的问题,从技术提升、能源节约、环境保护等角度提出了采用小粒煤技术、载气温度自动控制技术、混热式热解技术、干熄焦技术和污水预处理技术等一整套升级改造方案,在满足节能环保要求的同时,推动实现内热式热解技术产业的技术升级。
[Abstract]:The most mature coal pyrolysis technology used in industry is internal pyrolysis technology. At present, the industrial scale of the internal thermal pyrolysis furnace is the largest, and the total scale of the unit has exceeded 200 million tons (measured by coal quantity into the furnace). There are some problems in this technology, such as backward control technology, poor gas quality, low comprehensive utilization of energy and serious environmental pollution, etc. In this paper, the technical progress and existing problems of internal thermal pyrolysis furnace are analyzed. From the point of view of technology upgrading, energy saving, environmental protection and so on, the technology of small particle coal, automatic control of carrier gas temperature, and heat mixing pyrolysis technology are put forward. A whole set of upgrading schemes, such as coke quenching technology and sewage pretreatment technology, can meet the requirements of energy saving and environmental protection, and promote the technical upgrading of internal thermal pyrolysis technology industry at the same time.
