Abstract:A 3 dimensional particle dynamic analyzer (3D-PDA) was employed to measure the gas-solid suspension flow in a lab-scale square cyclone separator with both downward exhaust exit and solid discharge. The particle concentration and diameter distribution at 2 sections were presented in this paper. At the upper part, e.g., at the section that is half of the inlet height from the separator top, the particle diameter at the front-right corner facing the inlet was found oberviusly larger than those at any other position. The particle diameter showed little difference at the section at the mid-height of the separator, while the particle concentration showed a little higher at the left-front corner and a little lower at the right-front corner. The particle concentration distribution was against particle fluctuating velocity.
Keywords: square cyclone; separator particle distribution; 3D-PDA measurement
