摘要

为实现医疗垃圾无害化、减量化和资源化处理,提高医疗垃圾的能质利用效率,提出基于等离子体气化的医疗垃圾制备氢气/甲醇系统,其中产氢系统（方案A）将医疗垃圾转化为氢气;产氢气和甲醇双燃料系统（方案B）将医疗垃圾转化为氢气和甲醇。所有方案均采用30 t/d等离子体气化炉,并从热力学和经济学角度评估和比较综合效益。结果表明,方案A和方案B的流程效率分别达到70.07%和67.96%,但由于废气的循环利用,方案B的系统?效率比方案A高出2.19个百分点。相较于方案B,方案A的动态投资回报期更短（为4.40 a）,净现值相对更高（为25556.62万元）。

Abstract

To achieve the harmless, reduced, and resourceful treatment of medical waste while enhancing energy and material utilization efficiency, a hydrogen/methanol production system based on plasma medical waste gasification technology is proposed to produce hydrogen/methanol. Among them, the hydrogen production system （scheme A） converts medical waste into hydrogen;The dual fuel system of hydrogen and methanol production （scheme B） converts medical waste into hydrogen and methanol. All schemes use a 30 t/d plasma gasifier and are evaluated and compared from a thermodynamic and economic point of view. The results show that the process efficiencies of scheme A and scheme B reach 70.07% and 67.96%, respectively. Due to the recycling of waste gas, the system breakdown efficiency of scheme B is 2.19 percentage points higher than that of scheme A. Compared with scheme B, scheme A has a shorter dynamic payback period of 4.40 years and a relatively higher net present value of 255.57 million yuan.
