General speaking , if it is the drying of the electuary and granular materials , which have relative large proportion , only the cyclone separator is needed 一般来说，比重较大的物料只需选择旋风分离器。比重较轻的物料需配套布袋除尘器，并备有气力送料装置供选择。
Gas - solid separator plays a vital role during the process . to this case , a new kind of cyclone , the horizontal square cyclone , has been presented in this paper 针对这一情况，本文对浙江大学热能工程研究所提出了一种可应用于锅炉改造中的新型旋风分离器? ?方形卧式分离器进行了试验和理论研究。
For the drying materials have different property , when it is equipped with dust catcher , the cyclone separator and cloth bag dust remover can be chosen both or chosen any one of them 由于干燥物料的性质不同，配套除尘设备时，可按需要而进行，可同时选择旋风分离器、布袋除尘器、也可选择其中一种。
In the first part , the development of cyclones has been summarized , including capability criterions for cyclone evaluation , factors about separation capability and development of flow field within cyclones and several classical cyclones 首先介绍了评价旋风分离器的性能指标、影响旋风分离器分离性能的因素和几种旋风分离器的分类方法，然后对目前旋风分离器内流场的研究进行了简要介绍。
The gas - particles two - phase flows in the horizontal pipe and u - beam separator were also studied in this thesis . electrical capacitance tomography ( ect ) is a new method to measure the volume distribution of solids . it is not affected by the opacity of particles 实验测量上，本文采用电容层析成象技术测量了旋风分离器内部颗粒的浓度分布，分析了颗粒在分离器锥体部分的浓度分布规律、概率及频谱特性。
Boiling drier , the other name is fluid bed , is composed of air filter , heater , main frame of boiling bed , star like feeder , cyclone separator , cloth bag dust catcher , high pressure centrifugal blower , and control board 沸腾干燥器，又称流化床，经过30多年的使用、改进，目前在制药、化工、食品、粮食加工等方面，越来越体现它的重要作用。它是由空气过滤器、沸腾床主机、旋风分离器、布袋除尘器、高压离心通风机、操作台组成。
In this paper theoretical and experimental studies are carried out on cross correlation techniques using electrical capacitance sensors applied to non - intrusive restrictive velocity and mass flow rate measurement in a cyclone separator . the mass flow rate is determined from two parameters , namely the solids velocity and the volumetric concentration 本文同时将电容层成象和相关技术结合，采用双层电容传感器测量了旋风分离器料腿中固体颗粒的断面浓度分布，同时得到了固体颗粒沿轴向和周向的二维速度。
This thesis designed and constructed a series of solid circulating loop devices , including cyclone separator , loop seal , external heat exchanger ( ehe ) and correspondent joining pipes . a data acquiring system was completed to realize the data real - time display and record the pressure of the whole system and air flow 设计和搭建了从炉膛顶部出口到底部进口的物料回送装置，包括旋风分离器，返料器，外置换热器和相关连接管道，编写了数据采集程序实现数据实时显示，并记录整个运行中床体各点压力、各处送风量。
