摘要
根据旋风分离器的结构特点和气流流动特点,旋风分离器的压力损失分为入口损失、边壁摩擦损失、旋转动能损失以及出口损失四部分。本文以旋风分离器切向速度模型为基础,给出了各部分压力损失的计算方法,并针对不同的旋风分离器模型,将其计算结果与实验结果及其他的压力损失理论模型进行了比较,结果表明该计算方法可行。
According to the characteristics of cyclone's structure and the gas flow pattern,cyclone's pressure drop consists of four main partial pressure drops due to gas expansion at the separator entrance,wall friction within the separator,swirling motion of gas,gas flow through the outlet pipe.This paper develops a new theoretical model based on the mathematical model of the tangential velocity.The calculated value is compared with the experimental data as well as with the other models for different dimensions of cyclones.The result indicates the theoretical model is feasible.
