增湿活化脱硫试验研究

在热态脱硫试验台上进行了喷水活化和蒸汽活化脱硫试验，并研究了在不同钙硫比，饱和温距、SO2浓度和烟气速度下的脱硫性能，研究表明，与单纯的吸收剂喷射技术相比，蒸汽增湿活化和喷水增湿活化，都可以提高脱硫效率，但喷水活化效果比蒸汽活化效果好得多，而且脱硫效率随钙硫比增加，饱和温距、SO2浓度及烟气速度的降低而升高；在喷水增湿活脱硫中，脱硫剂浆滴的脱硫作用远远大于脱硫剂吸温脱硫作用。

Experimental Investigation of Humidification Activated Desulfurization

Spray water activated and steam activated desulfurization tests were conducted on a hot state desulfurization test stand. Also investigated were the desulfurization performance under different values of Ca/S ratio, saturation approach temperature, SO 2 concentration and gas speed. The results of the investigation indicate that as compared with a pure absorbent spray technique both the steam humidification activation and spray water humidification activation can contribute to an enhancement of desulfurization efficiency. However, the spray water activation is much more effective than steam activation. Moreover, there will be an enhancement in desulfurization efficiency in case of an increase in Ca/S ratio and a decrease in saturation approach temperature, SO 2 concentration and flue gas speed. As regards desulfurization by spray water humidification activation the desulfurizer droplets play a by far greater role in desulfurization than the desulfurizer moisture sorbent.
