石灰石/石膏法脱硫效率分析

为满足环保法规对SO2排放浓度的要求,发电企业在保证脱硫系统稳定运行的同时,还必须维持较高的脱硫效率。石灰石湿法脱硫是一个SO2扩散吸收、化学反应的复杂过程,任何影响这一过程的因素都会对最终的脱硫效率产生影响。通过对吸收塔浆液pH值、石灰石品质、烟气量、液气比、烟气停留时间及流速等主要影响因素的分析,指出提高脱硫效率的措施。

Analysis of Desulfurization Efficiency of Limestone/Gypsum FGD

The power plants not only need to ensure stable operation of the desulfurization system,but also maintain high desulfurization efficiency,for meeting the requirement of the SO2 emission concentration.The wet desulfurization is a complex process,which includes SO2 absorption and chemical reaction;any factors that influence on the process will eventually have an impact on the desulfurization efficiency.Some measures are pointed out to improve the desulfurization efficiency by analyzing the main influence fact...
