摘要
Abstract
The measurement of gypsum particle size distribution in desulfurization gypsum slurry of coal-fired power plants is mainly based on offline sampling method,which has problems such as long time consumption and low efficiency.In this paper,an online measurement method based on digital holography technology is introduced to realize the online measurement of the particle size distribution of gypsum particles in desulfurization gypsum slurry.Based on the above purpose,an on-line measurement experimental system was set up to measure the particle size of desulfurization gypsum slurry in the desulfurization gypsum slurry,and the results showed that the online measurement of the particle size distribution of desulfurization gypsum by digital holographic technology was more accurate,and the maximum absolute error with the median diameter(Dv50)value measured by the laser particle size analyzer was 3.73 μm.In addition,the morphology of desulfurization gypsum particles and limestone particles was observed by digital holographic technology to find the differences between them,and compared with the observation results of electron scanning microscope,the results showed that there were significant differences in the appearance characteristics of the two particles,which could be used as the basis for distinguishing desulfurization gypsum and limestone particles to improve the accuracy of particle size distribution measurement of desulfurization gypsum particles.关键词
