Abstract:

Application of particle image velocity(PIV)techniques for measuring particle size distribution and total number in an activation chamber of desulfurization system is introduced. Watersheld algorithm is used to choose the suitable initial gray level threshold which is used to change the gray level images taken by PIV to black and white ones, then every particle in an image is isolated totally. For every isolating particle, its contour is tracked by the edge enhancement filter function and kept by Freeman’s chain code. Based on a set of particle’s chin code, its size and size distribution are calculated and sorted. Finally, the experimental data of calcium particles and water drops, separately injected into the activation chamber, and the error analysis of data are given out.
