基于Fluent废塑料薄膜旋风分离过程的研究

Research on Waste Plastic Membrane Separation in the Cyclone Based on Fluent

采用旋风法对不同密度的废旧塑料薄膜进行分选,运用Fluent流体仿真软件中的欧拉双流体模型,对废塑料薄膜颗粒在旋风分离器中的运动进行了模拟仿真。根据不同种类废塑料颗粒的密度不同,所受重力以及在旋风分离器中所受离心力不同,将会产生不同的运动轨迹,使用旋风分离器将其分离,得出不同风速大小、不同颗粒直径时的分选效率,找出最适合的风速和颗粒粒度大小,从而使不同种类塑料颗粒达到高效分离,为进一步处理塑料垃圾奠定基础。

Whirlwind is applied to separate different density of the waste plastic membrane and Euler dual fluid model in FLUENT software is used to conduct numerical simulation for waste plastic membrane particle motion in the cyclone. As dif- ferent plastic particle has different density, the gravity and centrifugal is also different and so it would produce different tra- jectory and be separated by the cyclone, and the wind speed and particle size is found. The appropriate wind speed and par- ticle size is found out and high efficiency separation of the different kinds of plastic particles can be achieved, which would lay a foundation for further processing of plastic waste.
