摘　　要：为进一步探究微纳米气泡发生系统的性能,基于喷射法原理,结合正交实验设计,探究了文丘里管内径、气泡发生器孔径和级数等因素对微纳米气泡数量的影响。实验测试表明:随着气泡发生器级数由1级~3级逐级增加,微纳米气泡数量会随着气泡发生器级数呈正相关增加,当气泡发生器级数为3时,微纳米气泡的数量达到最多,此时背压约为0.4 MPa;随着气泡发生器孔径由0.7 mm增加至0.9 mm,微纳米气泡数量会随着孔径的增加呈先增加后减少的趋势,当气泡发生器孔径为0.8 mm时,微纳米气泡的数量约为22 046个,达到最多;而随着文丘里管内径由2.7 mm增加至2.9 mm,微纳米气泡数量会随着文丘里管内径的增加呈线性关系逐渐减少。该研究为微纳米气泡发生系统的应用提供了重要的设计依据。In order to further explore the performance of micro-nano bubble generation system,based on the principle of injection method,combined with orthogonal experimental design,the effects of the inner diameter of Venturi tube,pore diameter and stage of bubble generator on the number of micro-nano bubbles were studied.The experimental results show that with the increase of bubble generator stage from 1 to 3,the number of micro-nano bubbles increases positively with the bubble generator stage.When the stage of bubble generators is 3,the number of micro-nano bubbles reaches the maximum,and the back pressure is about 0.4Mpa.With the increase of bubble generator pore size from 0.7mm to 0.9mm,the number of micro-nano bubbles will first increase and then decrease with the increase of pore size.When the bubble generator pore size is 0.8mm,the number of micro-nano bubbles is about 22046,reaching the maximum.However,with the increase of the inner diameter of Venturi tube from 2.7mm to 2.9mm,the number of micro-nano bubbles decreases linearly with the increase of Venturi tube inner diameter.This study provides an important design basis for the application of micro-nano bubble generation system.
