亚硫酸法糖厂中和汁絮凝的破碎与重絮实验研究
Experimental Investigation of Fragmentation and Re-aggregation in the Flocculation of Neutralized Cane Juice in Sugar Factory with Sulfitation
摘要
Abstract
Flocculation experiments were conducted on the neutralized juice of sugarcane sulfite sugar factory at different stirring speeds at 100℃.By measuring the scale and fractal changes of flocs over time,the fragmentation and flocculation laws of flocs are studied,and flocculation kinetics are established.The results showed that under high temperature conditions,the neutralization juice quickly completed flocculation in rapid mixing,and continued stirring caused fragmentation and heavy flocculation of the flocs,resulting in a decrease in the equivalent diameter of the flocs and a decrease in porosity.After the reaction equilibrium,within the range of 17 s-1<G<41 s-1,the equivalent diameter of flocs increases first and then decreases with the increase of G,and the two-dimensional fractal dimension value continues to increase.This article establishes dimensionless relative equivalent diameter D and shear time Gt,and regress the experimental data to obtain the equation D=exp(-0.0035Gt).关键词
