摘　　要：为了提高固体垃圾废物的处理能力,实现垃圾废物的多元化利用,提出了一类基于垃圾衍生物(RDF)等离子气化与电解水补氢耦合轮胎热解制取甲醇、油等的新型一体化集成系统。该系统以等离子气化炉为主体核心,带动轮胎热解子系统工作,实现了能量的梯级利用。结果表明:该系统的能量效率为58.24%,[火用]效率为64.41%,能量损失的主要来源在于甲醇合成部分,而[火用]损失则主要在于等离子气化部分;根据经济性分析结果,该系统的总投资为3 566.56万元。在系统寿命为25 a,动态回收周期为3.15 a,最终系统的净现值可达到17 177.10万元。To enhance the treatment capacity of solid waste and achieve diversified utilization of waste,a novel integrated system for producing methanol and oil was proposed based on the coupling of refuse-derived fuel(RDF)plasma gasification,hydrogen supplementation from water electrolysis,and tire pyrolysis.The system centered on a plasma gasifier which drives a tire pyrolysis subsystem,achieving staged utilization of energy.Results show that the energy efficiency of the system is 58.24%and the exergy efficiency is 64.41%,with main energy loss in methanol synthesis and main exergy loss in plasma gasification.According to the results of the economic analysis,the total investment of the system is 35.6656 million yuan.With a system life of 25 years and a dynamic payback period(DPP)of 3.15 years,the net present value(NPV)of the final system can reach 171.7710 million yuan.
