[0002] A large amount of high-temperature furnace gas is generated during the production process of a closed calcium carbide furnace. The furnace gas temperature is generally 400-900℃, and the dust content is about 50-150g / Nm3. After the furnace gas is released from the calcium carbide furnace, it is initially cooled by the water-cooled clean gas flue and then enters the furnace gas purification device. The rough gas fan draws the furnace gas into the sedimentation bin, air cooler, and air cooling bin in turn, and sends it to three bag dust collectors for fine filtration. During the sedimentation, 40-50% of the large particles of dust in the furnace gas are removed, and the furnace gas temperature before entering the air cooler is about 400-600℃. After cooling and dust removal by the air cooler, the temperature is reduced to 180-250℃ in the air cooling bin. Under the action of the clean gas fan, it is sent to the lime kiln as fuel. The solid dust purification ash collected by the sedimentation bin, air cooler and bag dust collector is transported to the purification ash bin by a chain scraper.
