摘要
一次能源的消耗不断加大,使世界能源紧缺的现状更加严峻,而可再生能源以其清洁、再生、高效的优势逐渐成为人们研究的热点。基于多能互补、能量梯级综合利用的思想,设计了多能耦合可再生能源制沼气系统,并对该系统的主要装置进行了选型。通过实例计算,分析了该系统的能量利用率、火用效率和经济效益,表明该系统是可行的。该系统的投资回收期为2.5年,能量利用率达到60%,火用效率达到57%。
With the increasing consumption of the primary energy, the shortage of energy source is more and more serious all around the world. Thus renewable energy has become a hotspot for its clean, renewable and efficient advantages. The biogas producing system with multi-energy coupled renewable energy was designed based on the thought of multi-energy complement arities and comprehensive cascaded energy utilization, and the main devices of the system were selected. The energy utilization, exergy efficiency and economic efficiency of the system were analyzed by a case calculation, which proved that the system was feasible. The investment recovery period of the system was 2.5 years, the energy utilization rate was 60%, and the exergy efficiency was 57%.
