- W4377989320 abstract "The light scattering method has the advantages of simple structure and good real-time performance in measuring the mass concentration of particulate matter. It is usually used to calibrate the laboratory standard particles to ensure the accuracy of measurement. However, the actual measured particle size of pollutant particles is complex and changeable, it is necessary to explore the scattering light intensity distribution law in multi-detection angles under different particle sizes. The numerical simulation results obtain scattering light intensity distribution of silica particles under different polarization state light sources, and get the appropriate range of detection angle. This paper mainly designs a set of device to measure the scattering light intensity and mass concentration of particulate matter. Meanwhile, the standard instrument TSI was used to measure the real-time change of the mass concentration of particulate matter. The results show that the scattering light intensity signal measured by photodetector is highly correlated with the mass concentration measured by the TSI standard instrument, and the mass concentration of the particles measured by the system is in good agreement with the standard instrument TSI. The scattering light intensity can effectively invert the real-time mass concentration of particulate matter. The experimental device is suitable for real-time measurement of particulate matter mass concentration." @default.
