摘要:
为利用铁矿石烧结工艺无害化处理废离子交换树脂,开展了废离子交换树脂与铁矿石混匀料共烧结的实验研究.在容量为80 kg的烧结杯实验系统中,进行了铁矿石混匀料中掺入废离子交换树脂质量分数分别为0,2%,4%,6%和8%的5组烧结实验,研究了废离子交换树脂的掺入对烧结过程参数、烧结成品质量参数及污染物排放特性的影响.研究结果表明:随着废离子交换树脂含量的增加,垂直烧结速度先增大后减小,当掺入2%时为最大;料层透气性指数及烧结成品含硫量增加,二元碱度和转鼓强度减小,筛分指数增大;SO2和CO2平均排放浓度增大,而NOxx平均排放浓度减小.
Abstract:
Experiments of sinter of iron ore mixture and spent ion exchange resin were carried out on the sinter pot with a capacity of 80 kg. The influences of different mass fractions(0, 2%, 4%, 6%, and 8%)of spent ion exchange resin doping into iron ore mixture on sintering process parameters, sinter quality and pollutants emissions were studied. The results show that with the increase of the mass fraction of spent ion exchange resin, the vertical sintering speed climbs up first and then declines. When mass fraction is 2%, the vertical sintering speed reaches the highest. The permeability index and the content of sulfur in sinter are increased; the basicity and the drum strength of sinter are decreased, and the screening index of sinter is increased. The average emission concentration of SO2 and CO2 are increased, while that of NOxx is decreased.
