Calculation method to separation efficiency of impeller type ventilation

摘要

摘要: 为研究叶轮式通风器分离特性并建立满足工程设计要求的分离效率计算方法，在对油滴进行了受力分析后，推导了油滴运动轨迹模型，结合油滴捕获条件，给出了不同工况条件下油滴的最小分离直径，进而实现了叶轮式通风器分离效率的理论计算。研究表明：在不同转速、通风量和通风器入口温度时，分离效率和最小分离直径计算值与实验值趋势一致；分离效率最大误差分别为0.95%、1.01%和1.01%；最小分离直径最大误差分别为1.33%、2.29%和6.20%。计算结果与实验结果吻合较好，该方法可为叶轮式通风器设计及分离性能优化提供参考。

Abstract: In order to investigate its separation performance and establish the method for calculating the separation efficiency compliant with the requirements of engineering design, stress analysis of oil droplet was conducted, the trajectory model of oil droplet was established, and the minimum oil drop diameter under different conditions was calculated combining with the oil droplet capture condition, finally realizing the theoretical calculation of impeller ventilator separation efficiency. Research showed that in different speeds, mass flow rates, and inlet temperatures, the separation efficiency and the minimum separation diameter were in agreement with the experimental values; the maximum errors of separation efficiency were 0.95%, 1.01% and 1.01%, respectively; the maximum errors of the minimum separation diameter were 1.33%, 2.29% and 6.20%, respectively. The calculation results were in good agreement with the experimental results. This method can provide a reference for designing the impeller type ventilator and optimizing its separation performance.
