摘要: 对木屑炭流态化活化反应工艺进行了过程设计,利用对反应过程进行物料和热量衡算的方法,结合流态化反应原理,建立了木屑炭流态化活化反应数学模型,即:假设过程中床层物料接近于全返混状态,床层中的物料组成与溢流出的物料组成相同。床层中的物料由宽粒度、宽重度分布的物料组成,为保证所有物料均匀流化,宜采用空塔速度沿轴向变化的锥形床。工业化规模试验结果表明:设计的流态化活化反应器装置操作稳定可靠,完全达到预定设计要求,很好地克服了流态化活化反应器装置的放大效应,建立的木屑炭流态化活化反应数学模型科学、可靠。

Abstract: The process design of fluidization activation reaction for sawdust charcoal was introduced. The author established a mathematical model and carried out the industrial-scale test by methods of material balance and heat balance of the reaction process, combining with the principle of fluidization reaction. The results showed that the designed fluidization activation reactor was a successful device. Besides the stable and reliable operation, and completely matching the preconceived design, the negative effect caused by the magnification of fluidization activation reactor was overcome. The mathematical model is scientific and reliable.
