Abstract:
The drying of detergent suspending liquor was investigated in an inert particles fluidized bed drierwith vertica-l hole distributor, and the effects of gas rate of entrance, part icles diameter, feed volume, init ial concentration, gas temperature of entrance and stat ic bed height on drying intensity were analyzed. At the same t ime, the drying intensity was compared with that of drier with tilted-hole distributor. The results show that the drying intensity increases with adding gas rate of entrance, feed volume, gas temperature of entrance or stat ic bed height , and decreases with adding particles diameter or initial concentration. If the hole shape of distributor from vertica-l hole to tilted-hole is changed, the drying intensity of drier can be enhanced also. A correlation formula with dimensionless number group is established to calculate the drying intensity.
