Dust collector
First Claim
Patent Images
1. A dust collector for removing at least one of dust and mist from a gas, comprising:
- a charger for electrically charging at least one of dust and mist contained in a gas;
a sprayer without charging means therein, located apart and downstream from the charger in a flow of the gas that sprays an uncharged dielectric material to at least one of charged dust and charged mist;
an electric field former that forms an electric field which subjects said uncharged dielectric material to dielectric polarization; and
a collector for collecting said dielectric material which has arrested at least one of charged dust and charged mist.

Abstract
A dust collector efficiently collects dust, especially fine dust (submicron particles). The dust collector, which removes dust and/or mist contained in a gas, includes a charger for charging the dust and/or mist contained in a gas, a sprayer for spraying the charged dust or charged mist or spraying a dielectric material to the charged dust or mist, an electric field former for forming an electric field for subjecting the dielectric material to dielectric polarization, and a collector for collecting the dielectric material which has arrested the charged dust and/or the charged mist.
