摘要
旋风分离器是火力发电厂颗粒脱除与筛分的主要设备，其内部流动特性直接影响旋风分离器的性能。为研究旋风分离器上部直筒段结构差异对其内部颗粒运动的影响，采用计算颗粒流体力学（computational particle fluid dynamics，CPFD）方法对直线型与螺旋型2种结构分离器内的气固两相耦合运动过程进行数值模拟。结果表明：螺旋型分离器直筒段的平均气流速度高于直线型分离器，同时其出口速度较大，在一定入口流速范围内，螺旋型分离器分离效果略占优势。研究结果为后期实际工程技术改造优化工作提供理论参考。
Abstract
Cyclone separator is the main equipment for particle removal and screening in thermal power plants
and its internal flow characteristics directly affect the performance of cyclone separator. In order to study the influence of the structural difference of the upper cylindrical section of the cyclone separator on its internal particle motion
the numerical simulation of gas-solid two-phase coupled motion in a linear and a spiral separator was carried out by using computational particle fluid dynamics (CPFD). The results show that the average air velocity of the straight section of the spiral separator is higher than that of the linear separator. At the same time
the outlet speed is large. Within a certain inlet velocity range
the spiral separator is slightly superior in separation effect. The research results provide a theoretical reference for the optimization of later practical engineering technology transformation.
