摘要
A novel wet electrostatic precipitator (WESP) is designed for effective control of fine aerosol from humid gases. It operates on the principle of unipolar particle charging in the corona discharge and particle precipitation under the field of their own space charge. The new precipitator is characterized by high gas velocity in the ionizing stage. Tests were carried out for gas with (NH(4))(2)SO(4), HCl and (NH4)Cl aerosol at particle number concentration up to 5.10(7)#/cm(3) and mass concentration 10-1000 mg/Nm(3). For test conditions one-field WESP ensures mass collection efficiency 90-97% and two-field electrostatic precipitator up to 99%. (C) 2009 Elsevier B.V. All rights reserved.
