沥青烟对焙烧烟气净化湿法脱硫系统影响的试验研究

Experimental study on effect of pitch fume on wet desulfurization system of fume treatment center

采取试验的方法研究沥青烟气对钙基湿法脱硫系统的影响,结果表明:沥青烟气中的焦油液滴能延缓石灰石脱硫浆液对SO_2的吸收,也能降低石膏的结晶效率,同时也造成石膏的纯度降低。

The influence of pitch fume on wet desulfurization system is studied via tests. The results indicate that tar droplets could delay the absorption of SO2 by limestone slurry and also reduce the crystalline rate and purity of gypsum.
