摘要
利用库尔特粒径检测技术,对一种优选结构液-液旋流分离管的分离特性进行了较为系统的实验研究。实验测得该旋流管的临界分离粒径为30μm,而相同条件下国外典型产品,即F型旋流管的临界分离粒径为60μm,表明这种优选结构旋流管的分离特性较F型旋流管显著改善;实验结果还表明该旋流管的分离特性随处理量的增加而提高,当处理量为10m^3·h^（-1）时最好;随溢流比的加大而改善,其最佳溢流比为4％～5％;此外,还考察了为含油浓度与粒径分布之间的关系。有关结果为科学严格地评价液-液旋流分离管的分离性能提供了科学依据。
The separation performance of an innovative liquid - liquid hydrocyclone proposed by the authors was studied experimentally by using the Coulter counter technique. The number, size and concentration of oil droplets were measured, and the grade efficiency curves were determined for different oil contents, flow rates and overflow ratios. The results show that the separation performance of the hydrocyclone is improved with the increase of flow rate and overflow ratio. The performance of the proposed innovative hydrocyclone is obviously better than that of the F - type hydrocyclone proposed by Southampton University. The best separation performance is obtained at the flow rate of 10 m3·h -1 and overflow ratio of 3% - 5%, and the critical diameter of oil droplet to be separated is as small as 30 μm. Meanwhile, this diameter is about 60μm in the F - type hydrocyclone under the same test condition.
