摘　　要：本文提出了一种新型的铁炭微电池电解反应器———填充流化床反应器 ,并对该反应器的水力学行为进行了研究。通过床层压降法测定临界流化气速 ,建立了关于临界流化气速Uc 的经验关联式 :Uc=0 .0 15 6C0 .2 7Vt0 .14 H0 .31。通过脉冲示踪物信号法测得停留时间分布密度函数E(t) 。An innovative reactor for ferrum-carbon micro-cell electrolysis (packed-fluidized bed) was presented and its hydraulic behaviors have been investigated in this study. An empirical correlation for critical air velocityg(U c) has been proposed as follow: U c=0.0156C 0.27V t 0.14H 0.31. Resident time distribution(RTD) was obtained by pulse tracer signal. It was showed that the hydraulic mixing characteristics of the reactor approximate to completely mixed reactor(CMR).
