Abstract

A novel wet electrostatic precipitator is designed for control of fine aerosol from humid effluent gases. It operates on the principle of unipolar particle charging in a DC corona discharge in a high velocity (> 20 m/s) ionizing stage and aerosol precipitation in the low velocity (< 3 m/s) collection stage under the field of particle own space charge. The high gas velocity in the ionizing section diminishes the corona suppression at high particle number concentrations of H₂SO₄ and HCl aerosol.
