摘要
为了实现粉尘质量浓度的精确测量,设计了光散射法、电荷感应法和振荡天平法3种粉尘质量浓度的测量方案,通过试验并与粉尘采样器的测量结果进行对比。试验结果表明:光散射法和振荡天平法在质量浓度较低时,测量精度较高;电荷感应法在高质量浓度范围内,测量精度较高;粉尘质量浓度测量的最优方案是光散射法与电荷感应法相结合。
In order to achieve accurate detection of dust concentration,three dust concentration detection methods were designed such as light scattering method,charge induction method and oscillation balance method.And then,the detection results were compared with the ones from the dust sampler.The detection results showed:the light scattering method and the oscillation balance method were of higher detection accuracy at low dust concentration;the charge induction method was of higher detection accuracy at high dust concentration;the optimal solution for the dust concentration detection was the combination of the light scattering.
