摘要
利用脉冲等离子体对垃圾焚烧烟气二■英的脱除进行研究,结果表明,较高的等离子体放电电压有利于二■英异构体的分解;过高的含水率不利于二■英异构体的分解;二■英在等离子体中的分解主要包括脱氯和氧化,产物是低氯异构体、烷烃和醇类物质,最终产物是CO_2和H_2O。在含水率19%,电源消耗能量2.6Wh/Nm^3时,二■英毒性当量降解率可达89.6%。研究结果对脉冲等离子体脱除生活垃圾焚烧烟气二■英的工业应用具有一定的指导意义。
The paper uses the pulse plasma device to study the removal of dioxins from incineration flue gas of refuse. The result shows that the higher discharge voltage of plasma is in favor of the decomposition of dioxins isomer, and the excessive water content is not conducive to the decomposition of dioxins isomer. The decomposition process of dioxins in plasma mainly includes dechlorination and oxidation, the products are low-chlorine isomers, alkane and alcohols' substances, and the final products are CO 2 and H 2 O. The degradation rate of dioxins toxicity equivalent in TEQ is 89.6% with 2.6Wh/Nm 3 of energy consumption and water content 19%. This research bears a certain guiding significance for the industrial application of pulse plasma removal of dioxin from the flue gas of the domestic refuse incineration.
