摘　　要：针对沥青混合搅拌楼散热问题,用红外摄像仪和K型热电偶来监测搅拌楼温度并采集温度变化数据,基于传热学对其进行散热研究,对比再次保温前后散热量的变化。研究表明:热料仓所对应搅拌楼区域外表面的热量损耗最大,再次加装保温层可以显著降低热量散失,优先对较高温度的区域再次加装保温层会取得更好的节能效果。In view of the heat dissipation problem of asphalt mixing plants,the infrared cameras and K-type thermocouples are used to monitor the temperature of the mixing plant and collect the temperature change data.Based on heat transfer theory,its heat dissipation is studied,and the changes in heat dissipation before and after reinsulation are compared.The research shows that the heat loss on the outer surface of the mixing plant area corresponding to the hot mixture silo is the largest,adding the insulation layer again can significantly reduce the heat loss,and preferentially adding the insulation layer again to the area with a higher temperature will achieve better energy-saving effects.
