  • 摘要: 文章对某500kA系列电解槽排放的电解烟气进行测试。净化系统出口处的粉尘平均含量为15.0 mg/Nm3,总氟平均含量为0.8 mg/Nm3;天窗排放的粉尘和氟化物的时间加权平均浓度分别是4.4、0.32 mg/Nm3;两处测试数据中粉尘和总氟均能分别满足《铝工业污染物排放标准》(GB 25465-2010)规定的20.0、3.0 mg/Nm3标准限值要求。电解槽的总氟集气效率为97.20%。除尘器的漏风率为0.56%,粉尘的净化效率是99.97%,氟化物的净化效率是99.7%。测试结果表明电解槽集气效率偏低,故为减少电解烟气污染物排放,应对现有设计进行改进,提高电解槽集气效率。
    Abstract: In this paper, the electrolytic fumes from 500kA series electrolytic tank were detected. At the outlet of the purification system, the average content of dust was 15.0 mg/Nm3 and that of the total fluorine was 0.8 mg/Nm3. The time weighted average concentrations of dust and fluoride emitted from the skylight were 4.4 mg/Nm3 and 0.32 mg/Nm3 respectively. The test data of dust and total fluoride in two places satisfied the standard limit of 20.0 mg/Nm3 and 3.0 mg/Nm3 respectively stipulated in the Emission Standard of Pollutants for Aluminum Industry (GB25465-2010). The total fluorine gas efficiency of electrolytic tank was 97.20%. The air leakage rate of dust collector was 0.56%. The purification efficiency of dust and fluoride was 99.97% and 99.7% respectively. The testing results showed that the gas collecting efficiency of electrolytic tank was low. Therefore, the existing design should be revised to improve the gas collecting efficiency of electrolytic tank for reduction of the electrolytic flue gas emission.
