✦ Synopsis

Numerical simulation of ceramic filter unit was carried out in order to predict the gas flow in the filter vessel during the pulse cleaning process using FLUENT code. The particle movement and particles distribution were analyzed using both the Lagrangian and Eulerian approaches. Ceramic filter unit modeled in the study is composed of six elements of commercial filter in the normal hexagon. In the comparison of the single filter cleaning and two filters cleaning coincidently, the last mode leads to more uniform gas flow in the filter vessel during the pulse cleaning process. So far the numerical results show a good approach to predict the particle distribution in the vessel and the particle deposition on the filter element. And this study will provide the base for the intensive study on the analysis of the gas-particle flow in the filter vessel.
