摘　　要：建立了振动流化床冷模试验装置，以陶瓷球、柠檬酸、尼龙１０１０等为试料，研究了一定振幅和较低开孔率下振动频率、床层高度、气速等参数对振动流化床床层压力降的影响，得出了振动对床层最小流化压力降降低的程度。he effects of vibro-frequency, height of bed and gas velocity at a fixed amptitude and lower per-foration on the pressure drop through the bed are studied experimentally in a model vibro-fluidized bed equipment with small ceramic spheres,citric acid,nylon-1010, etc, as the sample materials.The degree of the pressure drop reduction by vibration at the minimum fluidization is deter-mined.
