摘　　要：以工程中实际运行生产的沥青混合料搅拌站为实验研究对象,文中提出基于现场温度实测的搅拌站的沥青加热存储过程能耗模型;根据搅拌站生产特点,将沥青加热储存过程划分为导热油加热、沥青加热、沥青保温使用、搅拌站停机四个阶段,分别建立基于实测温度和传热理论的能耗计算模型;根据能耗计算模型和实测温度数据,计算沥青加热储存过程总能耗。研究结果表明:连续施工工况下,单罐50 t基质沥青和单罐50 t改性沥青在整个加热储存生产过程的总能耗分别为6682.08,6290.88 MJ,对比验证搅拌站沥青加热实际消耗的燃油能耗误差为5.79%~22.60%。结论可为搅拌站沥青加热储存过程能耗研究提供理论参考。Taking an asphalt mixing plant in actual operation as the research object,this paper proposes a model of energy consumption in the asphalt heating and storage process in the mixing plant based on the actual temperature measurement.According to the production characteristics of the mixing plant,the asphalt heating and storage process is divided into four stages:heat transfer oil heating,asphalt heating,asphalt insulation use,and mixing plant shutdown.For each stage energy consumption calculation models based on measured temperature and the heat transfer theory are established separately.Based on the energy consumption calculation models and the measured temperature data,the total energy consumption in the asphalt heating and storage process is calculated.The results show that under continuous construction conditions,the total energy consumption of a single tank of 50 t base asphalt and a single tank of 50 t modified asphalt during the entire heating,storage and production process is 6682.08 MJ and 6290.88 MJ respectively.A comparison with the actual consumption of asphalt heating in the mixing plant verifies that the fuel energy consumption error is from 5.79%to 22.60%.This conclusion can provide theoretical reference for the study of energy consumption in the asphalt heating and storage process of mixing plants.
