Abstract

An electric dust collecting device is provided. The electric dust collecting device according to an embodiment includes a mixing part into which outside air flows, an electrostatic sprayer configured to spray droplets charged to the mixing part to be combined with contaminants contained in outside air, a dust collecting part configured to form an electric field and adsorb droplets combined with contaminants, and a draining part combined with the dust collection part to discharge the droplets adsorbed in the dust collecting part.

First claim

What is claimed is:

1. An electric dust collecting device, comprising:
a mixing part into which outside air flows;
an electrostatic sprayer configured to spray charged droplets into the mixing part so that the charged droplets combine with contaminants contained in the outside air;
a dust collecting part configured to form an electric field and adsorb the charged droplets combined with the contaminants; and
a draining part combined with the dust collection part to discharge the charged droplets combined with the contaminants adsorbed in the dust collecting part,
wherein the dust collecting part comprises:
a charging part and an absorption part oppositely combined with the charging part, and configured to absorb the charged droplets combined with the contaminants passing through the charging part, wherein the charging part comprises:
a plurality of charge wires disposed along a length direction of the charging part to allow power to be applied to an upper end part of the plurality of charge wires, and disposed in parallel to each other along a width direction of the charging part; and
a plurality of ground plates disposed between the plurality of charge wires,

wherein the draining part comprises:
a plurality of condensation members combined with lower end parts of the plurality of ground plates.

2. The electric dust collecting device as claimed in claim 1 ,
wherein the charging part comprises a charging part cover for covering the plurality of charge wires and the plurality of ground plates, and
wherein the charging part cover includes a plurality of draining holes being formed to face the plurality of condensation members.

3. The electric dust collecting device as claimed in claim 2 , wherein
the condensation members include insert grooves into which the lower end parts of the plurality of ground plates are insertable, and inclination parts for covering part of both side surfaces of ground plates and inclined downwardly toward the draining holes.

4. The electric dust collecting device as claimed in claim 1 , wherein
the draining part includes a first draining guide unit disposed under at least one of a upper end parts of the plurality of ground plates or the lower end parts of the plurality of ground plates, and extending along the width direction of the charging part.

5. The electric dust collecting device as claimed in claim 4 , wherein the draining part includes a second draining guide unit disposed under a lower end part of the plurality of charge wires, and extending along the width direction of the charging part.

6. The electric dust collecting device as claimed in claim 5 , wherein the second draining guide unit includes a draining guide part protruding outwardly from a lower end part of the charging part and inclined toward a bottom surface of the mixing part.

7. The electric dust collecting device as claimed in claim 6 , wherein
the charging part comprises a plurality of winding parts disposed on the lower end part of the charging part, and around which each of the plurality of charge wires are wound, and
wherein the plurality of winding parts are combined on the second draining guide unit.

8. The electric dust collecting device as claimed in claim 7 , wherein
the winding part further comprises a draining hole disposed under a lower end part of the winding part, and opened toward the draining guide part.

9. The electric dust collecting device as claimed in claim 5 , wherein
the draining part comprises a third draining guide unit disposed between an upper end part of the plurality of charge wires and a charging part cover, extending along the width direction of the charging part, and having both ends of the third draining guide unit protruding to an outer side of the charging part cover.

10. The electric dust collecting device as claimed in claim 1 , wherein the electrostatic sprayer comprises:
an accommodation part configured to store water;
a first electrode part configured to apply a voltage to the accommodation part;
a nozzle part combined with the accommodation part and configured to spray the charged droplets to the mixing part; and
a second electrode part disposed between the nozzle part and the mixing part and to which an electrode opposite to an electrode of the first electrode part is applied.

11. The electric dust collecting device as claimed in claim 10 , wherein the nozzle part comprises:
a nozzle plate combined with the accommodation part, and including an opening; and
a nozzle film combined with the nozzle plate, and including a plurality of spraying holes.

12. The electric dust collecting device as claimed in claim 11 , wherein the second electrode part comprises:
a frame in a ring shape including an opening in a shape corresponding to an arrangement of the plurality of spraying holes; and
a plurality of second electrode wires disposed to cross the opening of the frame.
