掌握原油罐储维温过程主要影响因素,对原油库实现节能降耗目的起重要作用.在建立动态热条件下含蜡原油罐储维温过程三维理论模型的基础上,提出了加热盘管空间结构、周向效应对罐内对流传热的影响,划分了内、外因素影响区以及过渡区域;采用多元非线性回归的方法,建立不同季节边界位置主控影响因素模型,定量表征了罐边界油温与内、外因素之间的作用机制.结果 表明:罐内大涡结构受无加热盘管区域局部湍涡影响,导致大涡结构向无盘管区域发生偏移.罐底低温区域受盘管周向效应影响较大,罐顶边界油品受内外因素影响大,形成最大厚度1.79 m的外界环境影响区;罐壁受保温层影响,只形成了内部维温热流影响区;冬季罐底形成了 0.13 m的外界土壤影响区.
Analysis of Main Factors Affecting the Temperature-Maintaining Process of Crude Oil Tank Storage Under Dynamic Thermal Conditions
Mastering the main factors that affect the temperature-maintaining process of crude oil tanks plays an important role in realizing the purpose of energy saving and consumption reduction in crude oil storage.Based on establishing a three-dimensional theoretical model for the temperature-maintaining process of waxy crude oil tanks under dynamic thermal conditions,the paper puts forward the influence of the space structure and circumferential effect of heating coils on convective heat transfer in the tanks,and divides the influence areas of internal and external factors and transition areas.Using multiple nonlinear regression method,the model of main influencing factors for different seasonal boundary positions is established to quantitatively characterize the interaction mechanism between the oil temperature at the tank boundary and the internal and external factors.The results show that as affected by the local turbulent vortex in the unheated coil area,the large eddy structure is deviated towards the area without coil.The low temperature area at the bottom of the tank is greatly affected by the circumferential effect of coil,and the oil at the top of the tank is greatly affected by internal and external factors,forming an external environmental influence area with the maximum thickness of 1.79 m.The tank wall is affected by the insulation layer,and only the internal temperature maintenance and heat flow influence zone is formed.In winter,an external soil influence zone of 0.13 m is formed at the tank bottom.
