摘　　要：根据旋风分离器的气固分离特点,定义用于描述旋风分离器气固分离过程的颗粒藏量参数为操作中旋风分离器有效分离空间内全部颗粒的质量,选用流化催化裂化平衡催化剂粉料,通过实验测量旋风分离器内颗粒藏量与入口速度和入口浓度的关系。结果表明:颗粒藏量随着入口浓度和入口速度的增大而增大;旋风分离器的颗粒藏量主要来源于旋风分离器环形空间顶灰环,其余部分是旋风分离器的器壁表面颗粒层。The particle reserves parameter for describing gas and solid separation process of a cyclone separator which was the total particle mass existed in the internal operation space of the cyclone separator was defined according to gas and solid separation characteristics in the cyclone separator. The experiment was carried out with the fluidized catalytic cracking equilibrium catalysts to measure the relation between particle reserves in the cyclone separator and inlet velocity as well as entrance concentration. The results show that the particle reserves increase with the increasing of inlet velocity and entrance concentration. The main part of particle reserves comes from the top dust ring in the a annular space of the cyclone separator. The other part comes from the granular layer on the wall surface.
