Method and apparatus for effectively removing sulfur oxides and dust in gas by ammonia based method

摘要

This invention belongs to the technical field of environmental protection, and particularly to a method and apparatus for effectively removing sulfur oxides and dust in gas by ammonia process. The invention further relates to a method and apparatus for effectively removing sulfur oxides and dust in gas by ammonia process, characterized in that the apparatus uses segmented control and multipoint ammonia-feeding process to fundamentally control ammonia slip and aerosol formation to achieve an effective effect of desulfurization and de-dusting.
