摘　　要：近些年来,气凝胶毡作为一种高效绝热材料广泛应用于石化行业中,在实际的配管工程中采用“气凝胶毡+传统保温材料”的复合保温结构,既能提高管道的保温性能,又能减少其保温层的厚度,同时保证了保温工程的经济性。在DN300、介质温度为400℃的管道上设计了一系列实验,探究复合保温结构中气凝胶毡保温层最适宜的厚度,并将气凝胶毡分别与硅酸铝针刺毯及岩棉等传统保温材料复合,逐一对比各自的保温性能。In recent years,aerogel felt has been widely used in the petrochemical industry as an efficient thermal insulation material.In practical engineering,the composite insulation structure of aerogel felt and traditional insulation material can improve the heat preservation performance,decrease the thickness of insulation layer and ensure the economics of insulation engineering.A series of experiments were designed for the pipe with a nominal diameter of 300 mm and a medium temperature of 400℃to explore the optimum thickness of the aerogel felt insulation layer in the composite insulation structure,and the aerogel felt was compounded with different traditional insulation materials such as aluminum silicate needle blanket and rock wool to compare their insulation properties.This research provides guidance for piping insulation in the petrochemical industry.
