Dust Removal Experiment and Numerical Simulation with Porous Ceramic Tube

Abstract

By the use of filtration experiment system with single ceramic tube, cold experiment and numerical simulation was carried out about the dust removal process. The experiment shows that airflow conforms to the linear Darcy law, the pressure drop increases with the increase of filtration velocity and dust load; with the increase of gas pressure, the permeability of porous ceramic decreases. Simulation shows that velocity and pressure drop values increase along the axial height from bottom to top and reach the maximum at the exit. Due to the differences of gas velocity or particle size, the amounts of sedimentary particles are different at the tube wall, larger velocity and smaller size particles trend to be more equispaced when they are trapped on the surface of tube.
