Abstract
Apparatus and a method for electrically sweeping particles from a gaseous effluent are disclosed which offer improved efficiency in removing particles of all sizes. A voltage is applied across two electrodes in such a way that a strong electric field can be generated between them. Ions of one sign enter the effluent gas stream from a thermionic ion emitter. A strong electric field is established between the electrodes to move the ions towards the oppositely charged electrode. These ions of one sign rapidly charge the particles because of the strong electric field. The charged particles are moved by the field and deposited on the oppositely charged collection electrode where they agglomerate in preparation for collection and disposal.
