US 2011/0209620 A1 · ELECTRIC DUST COLLECTOR

Abstract

An object of the present invention is to provide an electric dust collector with its dust collecting performance being improved for collecting dust-like particles contained in a gas, whereas the increase in size thereof is being suppressed. An electric dust collector 10 distributes a gas G that has flown into a distribution chamber 90 to a plurality of charging flow paths 58 in a casing 12 thereof, causes the distributed gas to flow from insides of the charging flow paths 58 into internal flow paths 28 through mesh filters 30 that are formed as parts of the dust collecting electrodes 16 and that have large surface areas per unit volume. Then, the gas G is discharged to a central chamber 33 through internal outlets 32. Subsequently, the flow of the gas G is controlled to be discharged to the outside through a gas outlet 24.

Dependent claims

An electric dust collector for collecting dust-like particles contained in gas with an electrostatic force, the electric dust collector comprising:

a casing through which the gas flows;
discharge electrodes arranged in the casing;
dust collecting electrode arranged in the casing and formed into boxes with one end having an outlet and having partition walls that partition inner and outer spaces, the dust collecting electrode at least partially made of metal mesh filter;
and
a voltage power applying unit for applying a driving voltage between the discharge electrodes and the dust collecting electrodes,
wherein the dust collecting electrode controls a flow of the gas in the casing so that the gas is discharged to the outside of the dust collecting electrode through the outlet, after the gas to be collected in the casing flows into the dust collecting electrodes through the mesh filter.
