Abstract
A dust collector for collecting dust, in which the rarefaction of a dielectric at the rear part of electric field forming apparatus is prevented, whereby the collecting efficiency can be increased. The dust collector includes a charging device ( ) for charging a substance ( ) to be collected, such as dust and mist, contained in a gas; a sprayer device ( ) for spraying a dielectric ( ) on the substance ( ) to be collected which is charged by the charging device ( ); an electric field forming device ( ), having first and second electrodes ( ) and ( ) which form a direct current electric field and dielectrically polarize the dielectric ( ) sprayed by the spray device ( ); and a dielectric collecting device ( ) for collecting the dielectric ( ) which has arrested the substance ( ) to be collected. The spray device ( ) includes grounding device ( ) and ( ) for electrically grounding the dielectric ( ) before being sprayed to let a charge of the dielectric ( ) escape.
