摘要:
在自制活性焦烟气脱硫脱硝静态实验系统上,考察了温度、空速、二氧化硫浓度、氧气浓度、水蒸气浓度、NO浓度、氨氮体积比等工艺参数对活性焦脱硫脱硝性能的影响,探索了使活性焦脱硫脱硝效率达到较优的工艺参数.结果表明:温度在120～180 ℃范围内时,温度越低越有利于活性焦的脱硫性能,而温度为130 ℃时,脱硝效果较好; 空速在小于1 000/h时,随着空速的增大,活性焦的吸附性能显著增加,继续增大空速,活性焦相对质量的增加明显降低; 烟气中SO2浓度小于2 L/m3时,活性焦对SO2的吸附量有明显增大的趋势,但SO2浓度继续增大时,超过了活性焦的饱和吸附量,吸附性能下降; 氧气、水蒸气体积分数含量均为6%时,大大促进了活性焦对SO2的吸附性能,含量过高或过低都不能达到最佳效果,而氧气浓度、NO浓度对脱硝性能影响不大.通过实验得到的较优脱硫工艺参数值为反应温度120 ℃、空速1 000/h、SO2体积比2 L/m3、O2体积分数6%、H2O体积分数6%时,脱硫效率高达98%; 脱硝工艺参数值为温度130 ℃、空速1 000/h、O2体积分数6%、NO体积分数500 mL/m3、φNH3/φNO=1时,脱硝效率为70%.
Abstract:
Using a static experiment installation of desulphurization and denitrification by active coke, the influence of the parameters such as temperature, space velocity, the concentration of SO2, O2 and H2O, the volume ratio of NH3 and NO on the absorption ability of active coke was studied. The best technology parameters of the desulphurization and denitrification were gained. The results show that the lower temperature is in favor of the adsorption of active coke in the range of 120 to 180 ℃; when the space gas is less than 1 000/h, with the increase in the space gas, the adsorption ability increases obviously; but its relative weight may decrease remarkably if the space velocity increases continuously. When the concentration of SO2 is less than 2 L/m3, the adsorptive capacity has a tendency of increasing; but if the concentration of SO2 increases and exceeds the saturated adsorptive capacity, the adsorption efficiency would decrease dramatically. The concentration of O2 and NO have almost no influence on the denitrification. The results also show that 6% and 10% is the best value of the volume fraction of O2 and H2O; 120 ℃ and 130 ℃ are the better temperatures; when space velocity is 1 000/h, the concentrations of SO2 and NO are 2 000 and 500 mL/m3, respectively, and the volume ratio of NH3 to NO is 1, the efficiency of desulphurization and denitrification can be up to 98% and 70%, respectively.
