摘　　要：提出了集成内循环双速流化床脱硫塔的工艺,利用激光多普勒粒子动态分析仪(PDA)对塔内的气固两相轴向速度、切向速度和颗粒浓度进行测量。对塔内的气固流动特性以及旋流结构和槽形分离器对内循环的贡献进行研究,为优化脱硫塔工艺设计提供依据。The integrated inner-circulating fluidized bed-fue gas desulfurization （CFB-FGD） technology based on the conventional CFB-FGD is presented. The characteristics of gas-solid two-phase flow were studied on the cold test model, which has two sections with various velocities. The gas-particle velocity field and particle concentration in the tower were measured using the phase-Doppler particle dynamic analyzer （PDA） system. The experimental results reveal the contribution of revolver and U-beam labyrinth separator to the inner circulating.
