摘要
针对海水脱硫后的烟气具有SO2浓度低、湿度大、温度低的特点,提出了在烟道内无需除湿预处理的直接采样测定SO2的方法,解决了国标法进行除湿采样或使用较先进仪器直接脱水测定带来的测定结果偏低问题。实际应用表明,该法比在烟道外使用的除湿法更加准确、经济。
The flue gas which was treated by seawater adsorption process has the character of low SO2 concentration, high humidity and low temperature, The standard method for sampling SO2 can not be used and the SO2 concentration can not be rnonitored with electric equipment directly because the condensation of steam in flue gas can influence on SO2 concentration and make the measurement result be lower, To avoid the condensation of steam, a new sampling method without any pretreatment is developed. The result indicates that the SO2 measurement result can be more accurate with this new sampling method than the others. Moreover, this method＇s feasibility and merit is discussed deeply in theory.
