【摘要】 在内径200mm,高度1100mm的喷淋塔内,采用Na2CO3作为吸收剂进行SO2吸收实验,重点研究了液气比(L/G)、空塔气速、进口SO2质量浓度、吸收液pH及初始浓度对脱硫效率的影响。通过实验得到该系统适宜操作条件:吸收液pH值在6.5～7.5之间,液气比在1～1.5之间,吸收液初始浓度5%,空塔气速1.6m/s,在此条件下,进口SO2质量浓度在3000mg/m3以内,脱硫效率可以达到80%以上。更多还原

【Abstract】 In diameter 200 mm and height 1100 mm spray tower,Na2CO3 used as the absorbent to do SO2absorption experiments.Main parameters affecting SO2 removal efficiency were studied for this process,including liquid-gas ratio(L / G),empty tower gas velocity,inlet SO2 concentration,pH value of the absorption solution and initial concentration.The experimental results show that SO2 removal efficiency may be over 80% under the following conditions: pH=6.5~7.5,L/G = 1~1.5,Na2CO3 initial concentration of 5%,Empty tower gas velocity of 1.6m/s,and the SO2 inlet concentration within 3000mg/m3.更多还原
