摘要

采用管式炉模拟垃圾焚烧研究垃圾中不同硫化合物、焚烧温度、Cd初始浓度以及垃圾焚烧停留时间对Cd迁移分布特性的影响。结果表明

硫化合物种类、焚烧温度以及Cd初始浓度对Cd的迁移分布有着重要影响。氧化性气氛下S和Na2S更易使Cd在底渣中分布

Na2SO3和Na2SO4更易使Cd在飞灰中分布;硫化合物对Cd的挥发性影响能力大小依次为Na2S

Abstract

By using tubular furnace

the municipal solid wastes(MSW) incineration has been simulated.The infuence of different sulphur compounds

incineration temperature

initial concentration of Cd

and remaining time of MSW incineration upon transfer and distribution behavier of the heavy metal Cd being studied.Results show that the kinds of sulphur compounds

incineration temperature

and initial concentration of Cd have important influence upon the transfer and distribution of Cd.Under oxidizing atomosphere

S and Na2S tend to increase Cd distribution in the bottom slag

Na2SO3 and Na2SO4 tend to increase Cd distribution in the fly ash.The effects of sulphur compounds upon volatility of Cd are successively in the order of Na2S
