Paper Abstract

The measurement of the dust emitting quantity is one of the important target in the environment monitoring of polluted sources. The design problem of measurement instrument for dust emitting quantity by light scattering principle are discussed in this paper. We have been investigated size distribution of dust particle emitting from thermal power plants. Light energy contribution of dust particle is studied by simulative experimental equipment. And we used a Self Scanning Photodiode Array (SSPA) in multi-ring cuneal to detect and transform the scattering energy and studied the influence of the size distribution of dust on scattering energy at small angle. We think that when design an instrument for dust emitting quantity by light scattering principle, we must consider that the size distribution of dust has influence on the light energy contribution and side scattering caused by small particles has influence on forward received single.
