Wet dust collecting apparatus

A wet dust collecting apparatus has a housing, a suction passage formed in the housing for sucking hot dust, a water tub arranged in the housing, a mist room formed in part by water in the water tub, and further defined by a partition plate arranged downstream of a chamber associated with the sucking passage. A dust filter is arranged downstream of the mist room, and a fan sucks hot dust into the suction passage, through a comb-toothed mist generator arranged between the chamber associated with the suction passage and the mist room. Dust-containing air is sucked in the suction passage and blown through the mist generator so as to vibrate the water surface thereby generating mist in the mist room. The hot dust is absorbed by the mist and cooled thereby. The hot dust containing mist is collected by the dust filter thereby separating the dust and water content from the air.
