冷热电三联供系统在餐厨垃圾处理项目中的应用研究
摘要:为实现餐厨垃圾的资源化利用，各地迅速新建餐厨垃圾处理厂。由于餐厨垃圾处理项目存在达产的滞后性及处理量的波动性等问题，造成餐厨垃圾处理项目中沼气利用系统规模及配置不合理，沼气发电机组运行效率低，经济性较差，沼气资源化利用未得到体现。以某新建餐厨垃圾处理项目为例，结合已投案例能耗数据，详细分析项目沼气产量，电负荷、蒸汽负荷等能耗数据，采用“以气定电，欠负荷”的设计原则确定沼气冷热电三联供(combine cooling, heating and power，CCHP)系统的装机规模和系统运行策略。最后通过与常规处理方式对比，从经济效益、节能效益和环境效益等3个方面综合分析了沼气CCHP系统的可行性及合理性。
Abstract：In order to realize the resource utilization of food waste, food waste treatment plants are rapidly built in everywhere. However, due to the lag reaching the production capacity and the fluctuation of treatment capacity of the food waste treatment plants, the scale and configuration of the food waste treatment plants biogas utilization system are unreasonable, the operating efficiency of the biogas generator set is low, the economy is poor, and the resource utilization of biogas has not been reflected. Taking a new food waste treatment plants project as an example, combining with the energy consumption data of the production case, analyze in detail the energy consumption data of the project's biogas production, electric load, steam load, etc., and adopt the design principle of "gas to determine electricity, underload" to determine biogas the installed capacity and system operation strategy of the combined cooling, heating and power (CCHP) system. Finally, through comparison with conventional treatment methods, the feasibility and rationality of the biogas CCHP system are comprehensively analyzed from three aspects: economic benefits, energy-saving benefits and environmental benefits.
