介绍空分塔基础结构形式与传热的分析,加热风管至基础本体表面、隔热层、隔热层至空分设备、基础底部土壤,通风管内空气与管壁对流等传热量及基础通风量的热工计算方法,并以某厂3200m~3/h制氧机空分基础为实例,进行了理论计算与实测数据比较,结果较为吻合。并指出地层温度对低温设备的地下基础有不可忽视的热影响,计算时必须予以考虑。图3表3参5。
This paper introduces the analysis of air-space tower’s foundation structure and heat transfer, heat transfer from the air duct to the base body surface, the insulation layer, the insulation layer to the air separation plant, the base bottom soil, the convection of the air in the air duct and the wall of the duct, Volume thermal calculation method, and a factory 3200m ~ 3 / h oxygen plant air separation foundation as an example, the theoretical calculation and measured data comparison, the results are more consistent. It is also pointed out that the formation temperature can not neglect the thermal influence on the underground foundation of cryogenic equipment and must be considered in the calculation.
