Abstract

In this paper a technique is introduced on visualization of emulsified droplets in gas stream by pulse laser sheet photography. By this technique fairly clear photographs of the concentration and velocity profiles of water droplets in an activation reactor were obtained. The results of the study show that with a venturi tube installed in the activator, the distribution of the droplets is more uniform than without it; the uniformity of the distribution of the droplets can improve the efficiency of the activation of the sorbent particles in the reactor. The picture of the collision of the droplets was obtained in the experiment, which could be used as basis for the study of the mechanism of humidified activation process. The results of the experimental study of the deposition of the droplets on the reactor walls is also described and discussed.
