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,研究文丘里管内径、气泡发生器孔径和级数等因素对微纳米气泡粒径分布的影响。经实验测试,结果表明:当文丘里管内径由2.7 mm增至2.9 mm,气泡粒径随内径增加呈先减小后增大趋势,即气泡的平均粒径由10.88μm先减小至3.069μm,后增大至7.997μm;当气泡发生器孔径从0.7 mm增加至0.9 mm,气泡粒径随孔径增加呈递减趋势,即气泡的平均粒径由4.106μm减至2.954μm;当级数由1增至3级时,气泡粒径随级数增加基本保持一致。In order to further explore the performance of micro-nano bubble generation system,based on the principle of injection method,the effects of venturi inner diameter,bubble generator aperture and stage on the particle size distribution of micro-nano bubbles were studied.The experimental results showed that with the venturi tube diameter increased from 2.7 mm to 2.9 mm,the particle size of micro-nano bubbles decreased first and then increasesd,that was,the average bubble particle size first decreased from 10.88μm to 3.069μm and then increased to 7.997μm.When the bubble generator was increased from 0.7 mm to 0.9 mm,the bubble particle size increased with the aperture increase,that was,the average bubble particle size decreased from 4.106μm to 2.954μm.When the stage increased from 1 to 3,the bubble particle size basically remained the same with the increase of the stage.
