Method for improving identification degree of low-luminosity dispersed-phase particles in multiphase system
The present invention provides a method for improving an identification degree of low-luminosity dispersed-phase particles in a multiphase system. The method comprises: adding additive particles into a multiphase system containing low-luminosity dispersed-phase particles before photographing the multiphase system to obtain an image including the low-luminosity dispersed-phase particles, wherein the refractivity of the additive particles is greater than that of the low-luminosity dispersed-phase particles. The method can enhance the luminosity of the continuous phase in the multiphase system, thereby causing a large gray difference between the continuous phase and the dispersed-phase particles, improving the identification degree of the low-luminosity dispersed-phase particles in the image for conducting accurate identification by image analysis software and further being capable of accurately measuring needed parameters such as particle size, concentration or speed and the like of the dispersed-phase particles in a multiphase reactor.
