在自制的冷态反应器中，以150μm铜粉为流化介质，对浅池式流化床反应器内部流体的流动特性进行了研究，并将实验测量结果与理论推导结果进行对照。结果表明：在该反应器内部填充了较大固相颗粒后，形成的流化池可以有效地延长流化时间。对流化池中驻留的流化粒子进行测量，推导出驻留率的计算公式：σ=-0.51lnu-0.4m/V+2.145。将该公式带入到Ergun方程中，得到整体床层的压降，即反应器总压降方程：Δp =150μu0d2p ×(1-ε)2ε3+74×ρu20dp ×1-εε3 Le +(1-σ)(1-εb)Leρ，得到冷态试验结果说明方程可以很好的阐述该反应器内部流体的流动特性。

The flow equation for a novel fluidized bed reactor which contained solid particles was presented and validated by cold state experiment. The results indicated that the sump of the reactor formed by adding some relatively big particles could prolong the fluidized time effectively. Through resident rate test, its calculation was deduced as σ= -0. 51lnu-0. 4m/V+2. 145. As the pressure drop consisted of pipe flow drop and resident drop owing to the resident effect and the resident drop, the resident rate was introduced into Ergun equation and the pressure drop equation was concluded asΔp = 150μu0d2p × (1 -ε)2ε3 + 74 × ρu20dp × 1 -εε3 Le +(1-σ)(1-εb)Leρ. The experiment of cold state experiments showed that the model could match the flow state very well.
