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.

Key words
