Base on the ultra-low emission reconstruction project of the 2×600MW unit desulfurization system in the Northwest China. The desulfurization system synergistic dedusting technology route achieves ultra-low emission of soot under the premise of maximizing the use of existing equipment. Through the comparison of the three-stage roof demister, Tube type dedusting and demisting device and condensing type dedusting and demisting device technology, the three-stage roof demister is stable, mature and reliable, and widely used. Under the same transformation conditions, the cost of the three-level roof demister is lower than the other two dust removal and demisting devices.
