Numerical Simulation and Analytical Evaluation of the Collection Efficiency of the Particles in a Gas by the Wire-Plate Electrostatic Precipitators

In this study, a numerical simulation model and an analytical method are introduced to evaluate the particle collection efficiency transport phenomena in electrostatic precipitator (ESP). Several complicated physical processes involved ESP, including turbulent flow, ionization of gas by corona discharge, particles’ movement, displacement electric charge. The attachment ions charges suspended particles media. Then, charged fluid move towards plate stick on it. comprises field, motions. wire-plate type ESP is investigated for diameter range 0.02 10 µm. It observed that field strengths current densities show considerable variation solution domain. Meanwhile, changing supply voltage charging wire diameters significantly affect acquired collecting efficiencies. Simultaneously, distance between electrodes main inlet velocity has important effect efficiency. influence different working conditions dimensions performance discussed.
