Abstract
Radial jet cyclone (RJC) is a new type of dust removal equipment based on the improvement of traditional cyclone which greatly improves the separation efficiency of small size particles and inevitably increases the pressure drop. In order to explore the comprehensive influence of the structure size and process parameters of the radial jet cyclone on its separation efficiency, this paper selected five main influencing factors: blade helix angle, blade length, vortex finder depth, airflow velocity and particle concentration to design a set of orthogonal experiments. Through analysis, the experimental results show that the flow velocity has the greatest influence on the pressure drop, followed by the blade helix angle, and the other three factors have a smaller influence. The insertion depth of the riser has the greatest influence on the separation efficiency. While the smaller the vortex finder depth is, the higher the separation efficiency. The other influencing factors are blade helix angle, airflow velocity, blade length and dust concentration.
