Dust collector

A dust collector that collects welding fumes, the dust collector comprising:

• a tank that stores water in a non-full state;
• a first tower that stands upright from an upper surface of the tank, and is configured to receive air containing the welding fumes from an upper part of the first tower and to guide the air to the tank;
• a second tower that stands upright from the upper surface of the tank, and is configured such that air discharged from the tank passes through the second tower;
• a bottleneck structure portion in which a vertically intermediate part of the first tower is narrowed;
• a mist generator configured to generate mist in the first tower;
• and
• a filter housed in the second tower, wherein:
• an eliminator is housed in a part of the second tower, and a plurality of the filters are housed above the eliminator at intervals,
• the eliminator includes a plurality of barrier layers, each barrier layer having a plurality of elongated main plate portions disposed on a same plane with gaps between the respective main plate portions,
• the gaps between the main plate portions of each barrier layer are arranged so as to be shifted from the gaps in an adjacent barrier layer in a direction transverse to the same plane,
• each main plate portion includes, at two ends, side walls extending perpendicular to the main plate portion, and tip ends of the side wall are bent at a right angle to face the main plate portion.
