摘要
利用窄脉冲电方法来消除垃圾焚烧炉烟气中的汞蒸气，并进行了１０ｍ＾３／ｈ烟气的工业性实验，汞蒸气的减少率η随气体温度的增加而减小，并与气体在电场中的停留时间ｔ、脉冲电压频率ｆ以及电晕功率Ｐ有关系式η１－ｅｘｐ（－ｋｆＰｔ）成立，对于初始浓度为２ｍｇ／ｍ＾３的汞蒸气，在一定条件下可达１００％的消除率。
This paper aims at remvoing mercury vapor from flue gas emitted by incinerator. A pilot flue gas tretment plant of flow rate of 10 m￣3/h was installed. An empirical formula η= 1-exp (- kfPt) was proposed, where η, f, t and P are removal efficiency , pulse repetition frequency, residence time and corona power, respectively. Under cerain conditions, a removal efficiency of 100% can be reached for an initial concentration of mercury vapor of 2 mg/m￣3.
