Abstract
|
Fluidization experimental device design and processing their own manufacturing , including Φ120mm × 2000mm fluidized bed and Φ400mm × 7300mm , fluidized bed , the various internal components as well as the dust removal system and data acquisition system , the experimental determination of the silicon powder fluidization . U- meter , the the powder concentration measuring instrument and the particle velocity analyzer , silica fume flow data collected from a large number of different size levels . Also studied the fluidized bed , gas distributor type and finger -shaped tube of silicon powder fluidization quality and clarity of the various factors that affect the quality of silica fume stream . The experimental results of cold model experimental basis for large - scale production of silicon powder particle size selection . Established by fitting to the experimental data , the the silicon powder bulk density and the critical fluidization velocity curve equation , established a standard differential pressure method to judge the quality of fluidization . Fluidized bed type , distributor type and the internal components of the quality of the silicon powder fluidization experimental studies , the experimental results obtained provide a reliable basis for industrial fluidized bed reactor design .
