摘要
为设计和优化深水气力提升装置并估算其输送效率,基于连续性方程及冲量方程,耦合能量方程,并考虑气体体积膨胀和截面含气率变化,建立了一种通用的气力提升三相流装置的理论分析模型。该分析模型的计算结果与文献试验数据的吻合性较好。利用本文模型针对工程实例的计算分析表明,增大输送管径可有效提高提升系统的输送功效。
In order to design and optimize the deep-water pneumatic lift device,and estimate its conveying efficiency,a general theoretical analysis model of pneumatic lift three-phase flow device is built on the combination of continuity equation,impulse equation and coupling energy equation,and by taking into account the variation of air expansion and sectional void fraction.The model-based calculation results are in good agreement with the experimental data in the literature.Its application shows that the efficiency of the lifting system increases with the increment of conveying pipe diameter.
