摘要
针对目前在石化生产装置中高温管道保温结构普遍存在的散热损失大、保温结构破损严重的现状,采用新型纳米陶纤绝热材料与高密度岩棉管复合保温结构,替代目前广泛使用的硅酸铝纤维棉、复合硅酸盐、硅酸钙卷材保温结构。由于纳米陶纤绝热材料导热系数极低,其与高密度岩棉管复合后的整体保温结构又兼具极高的强度,大幅降低了高温管道保温后的散热损失,显著延长了高温管道保温结构的使用寿命。
In view of the problems in the thermal insulation structure of high-temperature pipelines in petrochemical units such as large heat dissipation loss and seriously damaged thermal insulation structure,a new composite thermal insulation structure of nano ceramic fiber thermal insulation material and high-density rock wool pipe is adopted to replace the widely used thermal insulation structures of aluminum silicate fiber cotton,composite silicate and calcium silicate coiled materials.The integral insulation structure,which is characterized by the extremely low thermal conductivity of nano ceramic fiber thermal insulation material and the high strength of high-density rock wool pipe,greatly reduces the heat dissipation loss of high-temperature pipelines and significantly prolongs the service life of insulation structure for high-temperature pipelines.
