摘要:
在流化床试验装置上进行垃圾焚烧,焚烧尾气采用管道喷射吸附工艺净化.在活性炭加料量为1.6 g/m3时,脱硫率为83%,脱硝率为88%,脱氯率为27%.试验可得:活性碳、高岭土和活性矾土3种吸附剂对垃圾焚烧烟气中酸性气体的净化效果活性炭效果最好,高岭土效果最差; 随着吸附剂加料量的增加,重金属的脱除率增加,且增幅逐渐趋缓.3种吸附剂对重金属的吸附能力比较表明:对Cd,Pb,Cu的吸附效果活性炭最好,高岭土次之,活性矾土最差; 而对于Hg活性矾土的吸附效果最好; 活性矾土对Cd也有较好的脱除效果.垃圾焚烧飞灰中多环芳烃主要以3环、4环和5环的形式存在,其他各环多环芳烃的数量较少; 烟气中主要是3环和4环多环芳烃,未检测到6环多环芳烃,2环和5环多环芳烃的质量浓度相对较低; 在喷入量相同的条件下,高岭土去除多环芳烃的效率最高,活性炭次之,活性矾土最低.总体而言,活性炭具有较好的综合吸附性能.
Abstract:
Municipal solid wastes(MSW)incineration was carried out in a fluidized bed test rig. The flue gas purifying was carried out in an in-pipe injection adsorption test rig. The experimental results are as follows. When the feedstock of active carbon is 1.6 g/m3, the desulfurization efficiency is 83%, the denitration efficiency is 88%, and the dechlorination efficiency is 27%. The order of purifying effect of three kinds of absorbents for acid gases from MSW incineration is active carbon> active bauxite> kaoline. Comparison of heavy metal absorption capacity of three kinds of adsorbents show that active carbon is the best additive to remove Cd, Pb and Cu, kaoline is inferior, and active bauxite is the poorest one. But active bauxite is the best additive to remove Hg and is also effective for removing Cd. PAHs in fly ash are dominated by three-, four-, and five-ringed PAHs, and PAHs in flue gas mainly includes three- and four-ringed PAHs. When the injecting quantum of additive is the same, the order of cleaning effect for PAHs is kaoline> active carbon> active bauxite. Three kinds of adsorbents have different purifying effects on acid gas, heavy metals and PAHs in flue gas from MSW incineration. In general, active carbon has better adsorption capability.
