摘要
为了掌握气动涡旋雾幕发生装置的雾化性能,依据气动涡旋雾幕形成机制架设相似试验平台,并围绕主要影响因素设计多因素正交试验,采用多因素回归分析法获得雾化半径预测模型,并对该装置的除尘效果进行试验验证。结果表明:射流风速与雾化半径的关系为正相关且影响较大,工作夹角和雾化压力为负相关;正交试验分析结果显示,对雾化半径的影响从大到小依次为射流风速、工作夹角、雾化压力。除尘效果试验检验结果证明:该装置所形成的旋转雾幕可将前端高浓度粉尘隔绝在雾幕之前,全尘和呼吸性粉尘降尘效率分别为93. 03%、87. 75%,对扩散的粉尘捕集效果较为显著。
In order to learn about the atomization performance of the pneumatic vortex spray curtain device,a similar experimental platform was set up according to the formation mechanism.Multi-factor orthogonal tests were designed considering main influencing factors and the atomization performance prediction model was obtained by multi-factor regression analysis.Experiments were carried out to verify the dust removal effect of the device.The results show that the jet wind speed is positively correlated with the atomization radius and it has great influence on the radius,that the spray working angle and the atomization pressure are negatively correlated,and that the squence of factors affecting atomization radius from big to small is the jet wind speed,the spray working angle and the atomization pressure.The dust removal effect experimental results prove that the pneumatic vortex spray curtain can isolate the high concentration dust,that the removing efficiencies of dust and respirable dust are 93.03%and 87.75%respectively,and that the effect on dust collection is more significant.
