文章在喷淋实验塔中，研究了氨法烟气脱硫的特性。将空气和气态二氧化硫按一定比例混合后的气体作为模拟烟气，用氨水作为脱除二氧化硫的吸收剂，对模拟烟气的进气温度、进气浓度、气速、液气比以及吸收液的pH五个因素对脱硫率的影响进行了逐一考察，获得了各因素与脱硫率之间的关系，并得到较适宜的操作参数。实验结果表明：随着液气比和吸收液pH的增大，脱硫率增大。随着模拟烟气进气温度、进气浓度和气速的增大，脱硫率降低。其中温度因素对脱硫率的影响不明显。实验得到适宜的操作参数为：常温下，模拟烟气气速为2．0m／s，液气比为10，pH为6．4时，对浓度为2000mg／m^3的烟气操作，收率可维持在85％以上，并在理论上对各因素和脱硫率之间的内在联系作了理论分析。

The characteristics of the process in ammonia-based FGD system were studied in an experimental-size spray tower. Simulated flue gas was obtained by mixing air and SO2（I） in certain ratio. The absorbent for removing SO2 was ammonia solution. Influencing factors such as temperature, inlet concentration of SO2 in simulated flue gas, gas velosity, liquid-gas ratio and pH value of absorbent were disscussed separately, out of which we＇ve drawn an accurate conclusion of relationship between absorption rate and each factor. According to the data we gained, the modified experemental operating conditions were obtained, which shows that absorption rate increases with liquid-gas ratio or pH value increasing ,but decreases with temperature, inlet SO2 concentration or gas velosity. The impact of temperature is not significant. The absorption rate of simulated flue gas at the concentration of 2000 mg/m3 is able to reach over 85 % when operating condition maintains steadily at normal atmosphere temperature with inlet velosity at 2.0 m/s, liquid-gas ratio at 10, pH value at 6.4, and a theoretical analysis about their internal interaction has been achieved.
