Research of Particles Distribution Function in Horizontal Liquid-Solid Circulating Fluidized Bed

摘要

A horizontal liquid-solid multi-tube circulating fluidized bed was designed to study the influence of front header distributor, liquid velocity, Kenics static mixer to various particle's distribution and discuss the pressure of front header to back header. The CCD image measurement and data processing system was used to study the particle distribution and the U-tube differential was used to measure the pressure of front header to back header. Experimental results show that the front header distributor can improve the particle distribution in the tube bundle of the fluidized bed; the particle distribution will be best in the tube when the liquid velocity is 0.6m/s and Kenics static mixer is in the tube; in the same condition, plastic particles distribution is better than corundum ball particles distribution.
