外循环式液-固流化床换热器实验研究

Experimental study on external-cycling solid-liquid fluidized bed heat exchanger

通过建立外循环式液固流化床换热器的实验台并进行大量的实验,得出了影响外循环式液固流化床换热器操作稳定性的主要因素及其在稳定操作情况下流速、喷嘴结构、插入深度和颗粒总量等对上升管及下降管稀相空隙率的影响规律。

By making an experimental apparatus of the external cycling solid liquid fluidized bed heat exchanger(ESLFBE) and conducting experiments for a wide range of variables by independently varying the conditions, the main variables that influence on the stability of ESLFBE and the regulars of velocity of flow,muzzle size, muzzle deepness and particle density influencing on voidages of ascend piper and descend piper under a steady work condition were given
