摘要
为确定快速热解反应器的设计参数,必须对热载体与生物质粉混合物的堆密度和滑动摩擦系数进行研究。为此,以石英砂和木粉为研究对象,对其不同质量比的混合物进行了实验研究,并对实验结果进行了分析。实验表明:热载体与生物质粉质量比在1:3~25:1之间时,混合物堆密度、滑动摩擦系数与热载体质量份数、热载体理论体积系数存在一定的线性关系。这些数据为热解液化工业示范装置的设计提供了依据。
In order to determine the design variable of Flash Pyrolysis reactor, we should study on the bulk density and friction coefficient about the mixture of heat-carrier and biomass powder. This article takes quartz sand and wood-flour as research object, and does research to the mixture which has different quality ratio and carries on the analysis to the experimental result, The experiment shows that: when the quality compares of heat-carrier and biomass powder from 1:3 to 25:1, there are certain linearity relations between bulk density and the quality number of heat-carrier, the sliding friction coefficient and the theory volume coefficient of heat-carrier. These data has provided the basis for industry demonstration of the pyrolytic liquefaction.
