摘要
介绍了丹江口铝厂电解铝烟气干法净化系统的设计方案、主要特点和使用效果。净化系统除尘效率高达 99 9% ,减少氧化铝损失折合人民币 2 2 4 694万元。延长了布袋及袋笼和脉冲阀的使用寿命 ,运行费用降低。可靠性提高 ,故障率明显降低。氟化物及粉尘 (烟尘 )的排放浓度均低于GB162 97 1996标准规定的排放值。为全国大量中小型铝厂自焙槽改预焙槽提供了成功的典范。
The design solution, main characteristics and the application of dry scrubbing system for aluminum electrolysis fumes in Danjiangkou Aluminum Plant are described The efficiency of dust elimination is as high as 99 9%, and the profit is 2 24694 M$/a from reducing alumina consumption And the operational costs are decreased by the longevity of the filter bag and pulse valve prolongation The break down is reduced remarkably, and the reliability is advanced by system utilization The discharge of fluoride and dust is consonant with the national standard GB16297 1996 It is a successful example for all middle and small aluminum plant countrywide
