| 中文摘要 |
| 采用干法错流移动床活性焦烟气净化工艺,在烟气处理量1 000m3·h-1的中试装置上进行了脱硫与除尘的连续试验.结果表明:装置操作简单,运行稳定;在烟气进口温度120℃、SO2浓度3 232～6 006mg·m-3、粉尘浓度89.3～1 599.7 mg·m-3、试验空速条件下,该装置可高效脱除烟气中的SO2和烟尘,净化后烟气含尘浓度低于50mg·m-3,满足国家标准《火电厂大气污染物排放标准》(GB13223-2003)中有关烟尘最高允许排放浓度的最严格的规定.在本装置中,吸附饱和的活性焦采用加热再生,再生过程产生的解吸气中SO2体积分数高达40.1%,可有效回收硫资源.具有良好的经济效益. |
| 英文摘要 |
| A developed flue gas desulfurization and dust removal process with a cross-flow moving bed filled with activated coke(AC) was tested on a pilot scale with the gas treatment capacity of(1 000) mg·h-1.The results show that a easy-operating and stable-running pilot-scale testing equipment can be reached,and under the conditions of testing space velocity,the feed gas temperature of 120℃,SO2 concentrations of(3 232)～(6 006)mg·m-3 and dust concentration of 89.3～(1 599.7) mg·m-3,the high efficiency of flue gas desulfurization and dust removal is reached with the purity of dust less than 50 mg·m-3.In the technology,the spent AC was regenerated by heating,and the SO2 concentration in the desorption gas is about 40.1%,which can be efficiently recovered as a sulfur resource.Favorable economy benefit can be reached by using the process. |
