Study on fine particle entrainment from dust hopper of the cyclone separator

摘要

The test powder was fed into the top of dust hopper directly to study the fine particles entrainment from dust hopper separately. It is found that the particle concentration distribution profile is convex along radial direction. The particle concentration near the dust discharge is the highest and gradually decreases upward. The empirical formulae of particle entrainment amount and it's penetration are obtained. The calculating results are in agreement with the experimental results wel1.
