下向流内循环生物流化床的水力动力学特性研究

Study on the hydrodynamic characteristics of DIBFBR

研究了下向流生物流化床的流态特征．结果表明下向流流化床降流区的流态接近于推流式，而升流区的流态接近于完全混合式，反应器可以模拟为一个推流式反应器和一个完全混合式反应器的串联．

A study is carried out on the hydrodynamic characteristics of DIBFBR in this paper.The results show that the flow in the down flow zone of DIBFBR approximates to plug flow and that in the up folw zone to constant stirred tank flow.The DIBFBR can be modeled as a plug flow reactor contacting with a constant flow stirred tank reactor.
