【摘要】 针对太湖疏浚淤泥,开展了水力旋流分离试验研究,研究了进泥浓度、进泥压力和底流口直径对分离效果的影响。结果表明,进泥浓度的增大对于底流物料的回收不利。对于研究使用的旋流器,最大的分级效率出现在粒径0.015~0.019 mm处,泥浆浓度10%~15%是较为有利的进料浓度范围。进料压力的增加有利于得到较多的底流产物,而且对提高底流产物的浓度有利。底流口径越大,会使更多的原料通过,有利于生产效率的提高,但是底流口径越小越有利于得到高浓度的产品。更多还原

【Abstract】 In order to study the effect of the feed concentration,the feed pressure and the diameter of bottom on seperation effect,we conducted hydrocyclone separation test using the dredged sediments from Taihu lake.The results showed that the increasing feed concentration wasn’t beneficial to underflow material recycling.For hydrocyclone using in the study,the largest classification efficiency came from the particle size0.015~0.019 mm,the slurry concentration 10%~ 15%was more favorable feed concentration range.The increasing feed pressure was beneficial to get more underflow product,and to improve the concentration of the underflow product.The bigger underflow diameter could make more raw material through,and be beneficial to the improvement of the production efficiency,but the smaller underflow diameter could be helpful to get a higher concentration of the product.更多还原
