Study on the Operation Characteristics of Electrostatic Fabric Precipitator

Abstract

Numerical simulation method was used in this paper and 3-D structure of model was established with Pro/Engineering. It is evident that the efficiency of electric-bag is related to internal fluid field. The internal fluid field characteristics (pressure field, velocity field, turbulence field and particle tracks) are obtained by the numerical simulation soft called Fluent, the result show that airflow distribution could be improved obviously by the flow deflectors in electrostatic precipitation area. And the distribution of DPM in filter area is non uniform, which would lead to various damage on bags and affect the operation of electrostatic fabric filter. All these work have important significance for the study of new dust removal technology, developments of high performance precipitator, reduction of dust pollution and control of air pollution as well.
