Abstract

Provided is a cyclone dust collector with a higher particle collection efficiency than before. The cyclone dust collector of the present invention includes a nozzle assembly including a plurality of the nozzles arranged within a first cross section defined by a plane containing a center axis of the cylindrical case and part of the spiral flow path intersecting with each other, the nozzles being adapted to spray the water mist in a direction along the first cross section.

Claims

1. A cyclone dust collector that includes, inside a cylindrical case, a spiral flow path defined by a spiral guide and a nozzle that sprays water mist, to combine particles to be removed that are contained in an air passing through the spiral flow path with the water mist and to centrifugally collect the particles on an inner surface of the cylindrical case for recovery, the cyclone dust collector comprising:

a nozzle assembly including a plurality of the nozzles arranged within a first cross section defined by a plane containing a center axis of the cylindrical case and part of the spiral flow path intersecting with each other, the nozzles being adapted to spray the water mist in a direction along the first cross section;

a partition bar that partitions the first cross section into a plurality of split regions, wherein the plurality of nozzles of the nozzle assembly are attached to the partition bar to spray the water mist to each of the plurality of split regions; and

a center pillar that extends along a central part of the cylindrical case, wherein;

the partition bar extends between the center pillar and an inner side face of the cylindrical case, and

the plurality of nozzles of the nozzle assembly are gathered at a substantially central position in a longitudinal direction of the partition bar to spray the water mist radially from the substantially central position.

2. The cyclone dust collector according to claim 1, wherein

the nozzle assembly is arranged at an upstream end portion of the spiral flow path.

3. The cyclone dust collector according to claim 1, wherein

all of the plurality of nozzles inside the cylindrical case are arranged closer to an upstream side of the spiral flow path.

4. The cyclone dust collector according to claim 2, wherein

all of the plurality of nozzles inside the cylindrical case are arranged closer to an upstream side of the spiral flow path.

5. The cyclone dust collector according to claim 1, wherein

the cyclone dust collector includes an inner wall arranged on an edge portion of the first cross section and adapted to make the part of the flow path narrower, and the nozzle assembly is arranged in a constricted part of the part of the spiral flow path that is made narrower by the inner wall.

6. The cyclone dust collector according to claim 2, wherein

the cyclone dust collector includes an inner wall arranged on an edge portion of the first cross section and adapted to make the part of the flow path narrower, and the nozzle assembly is arranged in a constricted part of the part of the spiral flow path that is made narrower by the inner wall.

7. The cyclone dust collector according to claim 3, wherein

the cyclone dust collector includes an inner wall arranged on an edge portion of the first cross section and adapted to make the part of the flow path narrower, and the nozzle assembly is arranged in a constricted part of the part of the spiral flow path that is made narrower by the inner wall.
