在对汽水分离装置中液滴运动过程中的相变现象描述和物理机理解释的基础上,结合压力变化条件下静止单液滴相变模型的基础和液滴运动模型,建立了单液滴运动相变模型。该模型给出了液滴运动过程中,由于流动阻力和局部结构改变造成压力降低,打破汽液相平衡而造成液滴的快速蒸发和汽液相平衡蒸发2个阶段的机理解释和数学表述,与已有结果和理论分析结果均较符合。该模型可以用于液滴在重力分离空间、旋风和旋叶分离器、波纹板分离器等汽水分离装置中运动相变过程中的分离效率计算,衡量液滴相变对汽水分离性能的影响,指导分离装置结构的优化设计。
Based on the description of the phase transformation and the explanation of the physical mechanism during the droplet movement in the soda separator, the single droplet movement model was established based on the single droplet phase change model and the droplet movement model under the condition of pressure change. Phase change model. The model gives the mechanism explanation and mathematical expression of the two stages of droplet rapid evaporation and vapor-liquid phase equilibrium evaporation caused by the pressure drop caused by the flow resistance and local structure change during the droplet movement, It is in good agreement with the results of previous and theoretical analysis. The model can be used to calculate the separation efficiency of droplets during the kinetic phase transition in the gravity separation space, cyclone and rotary vane separator, corrugated separator and other separators. The model can be used to measure the effect of droplet phase transformation on the separation performance of the soda and water. Optimal Design of Guiding Separating Device Structure.
