摘要
以N2和CO2混合气模拟燃烧烟气,研究了鼓泡反应器的高径比以及反应条件对氨法烟气脱碳性能的影响。实验结果表明:在相同高径比的条件下,CO2吸收率随氨水质量分数的增加、反应温度的升高而逐渐增大,随进气CO2体积分数和模拟烟气流量的增加而逐渐减小;CO2吸收率随高径比的增加而增大,在高径比为3.98、氨水质量分数为28%、进气CO2体积分数为10%、模拟烟气流量为1.0 L/min、反应温度为40℃的条件下,CO2吸收率最高可达100%。
Using the mixture of N2 and CO2 as simulated combustion flue gas,the effects of the ratio of height to diameter of bubbling reactor and the reaction conditions on the decarbonization of flue gas by ammonia process were studied.The experimental results show that：With the same ratio of height to diameter,the CO2 absorption efficiency is increased with the increasing of the aqueous ammonia mass fraction and the reaction temperature,and decreased with the increasing of the inlet CO2 volume fraction and the gas flow;The CO2 absorption efficiency is increased with the increasing of the ratio of height to diameter,and under the conditions of the ratio of height to diameter 3.98,aqueous ammonia mass fraction 28%,inlet CO2volume fraction 10%,gas flow 1.0 L/min and reaction temperature 40 ℃,the highest CO2 absorption efficiency is 100%.
