Simulation of Airflow Distribution of Parallel-Type Electrostatic Fabric Filter in Coal-fired Power Plant

The structure was introduced, status of parallel-type Electrostatic Fabric Filter were researched, and the factors influencing collection efficiency were analyzed in the paper. With software of Gambit which also meshed the calculating region, Three-dimensional structure model of the precipitator was established. And then the numerical simulation of the air distribution characteristic was carried on with software of fluent 6.2, set the boundary conditions, standard k-ε 2-equation model and SIMPLE algorithm; Then draw the path line and contour chart of the cross-section, obtained the mean square deviation value, analyzed the airflow distribution situation and the reasons for its uneven; By setting appropriate opening rate of the airflow distribution plates and collection plates to improve the air distribution situation. The results show that the airflow distribution can be uniformed by improving the opening rate of the collection plates. The numerical simulation result is more reasonable and can be used as the reference of optimizing the structural design of Electrostatic Fabric Filter.
