摘要: 以某蔬菜废弃物处理和循环利用系统为研究对象,对6个月试运期的运行数据进行分析.结果显示,系统存在运行能耗大、余热回收不充分、蔬菜废弃物资源回收利用不完全的问题.因此,提出针对系统供能侧设备运行和调控方式的运行策略优化方案,采用沼气内燃机作为动力设备,优化余热回收过程的热电联产系统,利用瞬时系统模拟程序对优化系统进行仿真模拟验证.结果表明,优化系统能源利用率达到83.76%,㶲效率为53.32%,运行成本节约44.61%,热力学性能和经济性均得到较大提升.

Abstract: Taking a large-scale treatment and recycling system of vegetable wasteas an object, the operation data of the system during the six-month trial operation period were analyzed. The results showed that the system had the problems of intensive energy consumption in operation, insufficient waste heat recovery, and incomplete recycling of vegetable waste resources. In response, an optimized operational strategy for the operation and regulation mode of equipment on the energy supply side of the system is proposed. A cogeneration system with a biogas internal combustion engine as the power equipment to optimize the waste heat recovery process is used, and TRNSYS is used to simulate and verify the optimization system. The results show that the optimized system achieves an energy utilization efficiency of 83.76%, a cogeneration efficiency of 53.32%, and a 44.61% reduction in operating costs, thereby significantly enhancing both thermodynamic performance and economic viability.

Key words: vegetable waste treatment, recycling, operational optimization, cogeneration, simulation verification, anaerobic digestion
