Abstract

The electrostatic precipitators (ESP), as the major dust removal devices, requires more advanced designing tools to effectively reduce the fine particulate matter (PM). In this paper a multidimensional population balance model (PBM) is proposed to describe the mechanisms including particle mitigation, coagulation/breakage, nucleation/condensation and deposition/re-suspension inside ESPs. The governing equation is solved after discretizations of space, particle size and velocity. The numerical investigation of a mechanistic lab-scale ESP at Tsinghua shows reasonably good agreements with experimental measured particle size distribution (PSD) and collection efficiencies. Therefore, the model is able to benefit the state-of-the-art design and retrofit of ESPs.
