摘　　要：流化床设备广泛应用于生物质快速热解生产中,其系统压降影响液体产物的得率。系统总压降包括直管压降、局部压降、流化床反应器压降、旋风分离器压降和冷凝器压降。为优化流化床系统在生物质热解过程中的参数,通过对流化床管路系统压降研究得到系统压降理论方程。通过理论计算可知,气体流量为30m3/h时系统总压降为6.342×103Pa。Fluidized bed equipment has been widely used in biomass fast pyrolysis and the pressure drop of its system influence the yield of liquid products. The system＇ s total pressure drop includes straight pipe pressure drop, partial pressure drop, the pressure drop of the fluidized bed reactor, cyclone pressure drop and condenser pressure drop. In order to optimize the parameters of fluidized bed system during biomass fast pyrolysis process and a pressure drop theoretical equation of the system is obtained through the study of the fluidized bed pipeline system. Theoretical calculation shows that the total pressure drop is 6.342×10^3Pa when the gas flow is 30m3/h.
