会泽铅锌矿锗生产系统,用φ0.6×8米电热回转窑灼烧锗单宁渣,生产锗精矿.原设计用布袋收尘器净化出窑含尘烟气.投产后因烟气湿度大、露点高、滤袋结露,不能正常运行,改用沉降室收尘.经测定,收尘效率仅32.77%,出口废气含尘达952毫克/标米~3,为国家允许排放标准的4.76倍,排放烟尘含锗平均4.12%,年损失金属锗184公斤,除造成环境污染外,锗金属大量流失. 针对生产存在的问题,昆明冶金研究所
Huize lead-zinc mine germanium production system, with φ0.6 × 8 m electric rotary kiln burning germanium tannin slag, the production of germanium concentrate. The original design of the bag filter to purify the kiln dust flue gas. The humidity is high, the dew point is high, the filter bag dew condensation, can not be normal operation, use the sedimentation chamber to collect dust.It is determined that the dust collection efficiency is only 32.77%, the exhaust gas of the exhaust gas reaches 952 mg / Standard 4.76 times, the average emission of germanium containing 4.12% of fumes, the annual loss of 184 kg of germanium metal, in addition to causing environmental pollution, a substantial loss of germanium metal.For the production problems, Kunming Institute of Metallurgy
