焦油渣和煤沥青焚烧处置实验研究
Experimental Study of Tar Dreg or Tar Pitch Incineration
摘要
Abstract
In this paper, co-incineration experiments of slag and organic polluted soils were conducted. Applicable technical process and conditions of tar dreg or tar pitch incineration were studied by analysis of the content of heavy metals and PAHs in the slag and exhaust gas. The results showed that when the burning temperature of the primary furnace was 600~900 ℃ and that of the secondary furnace was no less than 1100 ℃, the retention time of the flue gas was no less than 2 s, and the outlet temperature of the quench cooler was no more than 150 ℃,the content of heavy metals in the slag was higher but less in the exhaust. The content of PAHs in the slag or exhaust was quite low because they were destructed by incineration or removed by the tail gas purification facility. The experimental results indicated that under the condition of 30% residue in the mixture, the tail gas was discharged in accordance with the discharge standards.关键词
