Numerical Simulation and Parameter Optimization of the Inside Intake and Outside Pressing Particle Collector

The issue of high dust concentration and the difficulty of head-on collection were investigated in this study. The theory of gas-solid two-phase flow was used to conduct numerical simulations on the air flow and dust concentration of the inside intake and the outside pressing particle collector using the FLUENT 6.3.26 software. The best optimization scheme was obtained by analyzing the simulation results of the air flow and dust concentration. Results indicated that when the diameter of the external cavity was 700 or 900 mm, the working surface of the working environment was not effectively improved. In comparison, when the diameter of the external cavity was optimized to 800 mm, most of the dust was trapped in the working face, and the working environment was significantly improved.
