利用单因素试验设计方法,针对气举式水力旋流器倒锥参数,开展不同参数下的性能优化研究.利用数值模拟方法,对不同倒锥高度、注气直径和注气速度下的流场特性及分布规律进行分析.结果表明,当倒锥高度为130 mm、注气直径为1.8 mm、注气速度为3.5 m/s时,分离效率达到最佳,较优化前提高了0.98%.对比倒锥参数优化前后的气举式水力旋流器油核分布形态,优化后油核均在倒锥结构上方形成,促进了旋流器分离性能的提升,验证了倒锥参数优化对气举式水力旋流器的重要性.
Study on the Influence of Inverted Cone Length on the Performance of Air-lift Hydrocyclone
Through employing the single-factor experimental design,the performance study under different parameters for the inverted cone parameters of air-lifted hydrocyclones was implemented,including employing numerical simulation to analyze both flow-field characteristics and distribution law which boasting of different inverted cone heights,gas injection diameters and gas injection velocity parameters.The results show that when the inverted cone height stays at 130 mm,the gas injection diameter is 1.8 mm and the gas injection rate is 3.5 m/s,the separation efficiency becomes best,which is 0.98%higher than that before being optimized.Comparing the oil core's distribution patterns in the air-lifted hydrocyclone before and after optimizing the inverted cone parameters,the oil cores optimized can be formed above the inverted cone structure and which promotes cyclone separation performance and verifies importance of the optimization of the inverted cone parameters for the air-lifted hydrocyclone.
