地源热泵式中、高温厌氧发酵加温系统比选分析
Comparison and Selection Analysis of Heating System of Mesophilic and Thermophilic Anaerobic Fermentation by Ground-source Heat Pump
摘要
Abstract
[Objective] To screen biogas project fermentation system.[Method] Heating system of mesophilic (biogas productivity at 1 m3/(m3 · d) and thermophilic (biogas productivity at 2.2 m3/(m3 · d) anaerobic fermentation by ground-source heat pump were compared,based on 70 m3/d daily biogas production of medium-sized biogas projects.Theoretical heating load of fermentation tank,initial investment and operating costs were calculated,and the economic benefits and technical feasibility were analyzed.[Result] The initial investment of thermophilic fermentation is lower than that of mesophilic fermentation by 83 000 yuan and annual operating costs of the heat pump is lower than that of mesophilic fermentation by 2 711 yuan.Investment returns net present value of thermophilic anaerobic fermentation system is 123 333 yuan.[Conclusion] Thermophilic fermentation system has a better investment returns in the life cycle of the heating system.关键词
