摘要
喷动床是一种可实现热量重复循环的高效反应器 .介绍了目前喷动床研究中出现的各种反应模型 ,从等温和非等温两个方面讨论了一维轴向、流管、半分割和流动反应耦合等各类模型的基本思想和理论及各自的特点 ,并提出了进一步发展的方向 .
Spouted bed was first introduced as a technique for contacting coarse solid particles,which has a quite high efficiency due to its well pattern of heat regeneration.The latest advances on the reaction model of spouted bed are discussed in this review.All previous reaction models are generally classified as two kind,isothermal or non-isothermal.For each kind,the one-dimensional model,streamtube model.semi-compartmental model,the combined model coupling two-phase flow dynamics and reaction kinetics are presented and compared in detail.Finally,the futural research ideal on the modeling of spouted bed reactor is proposed.
