摘要
根据湿式石灰石—石膏法脱硫的工艺特点,研究得出浆液中Mg2+浓度与除雾器出口烟气所携带的液滴中Mg2+浓度相等,据此结论,在除雾器出口进行等速取样,抽取烟气5m3,根据测定取样系统中微纤维过滤器洗液、采样管洗液及空白微纤维过滤器洗液中的Mg2+浓度、吸收塔浆液密度、吸收浆液滤液中Mg2+的浓度,来计算除雾器出口的烟气携带液滴量。
Based on the technological features of the desulfurization by wet limestone-gypsum method the authors have revealed through a study that Mg2+ concentration in slurry is equal to the concentration of Mg2+ in the droplet entrained by the flue gas at a demister outlet. On the basis of this conclusion a constant speed sampling was performed at the demister outlet with 5m3 of flue gas being extracted. On the basis of a determination of the Mg 2+ concentration in a micro-fiber filter wash liquid in the sampling system, in a sampling-tube wash solution and in a blank micro-fiber filter wash liquid, as well as the slurry density in an absorption tower and the concentration of Mg 2+ in an absorption-slurry filtering liquid, calculated was the liquid droplet quantity entrained by the flue gas at the demister outlet.
