The desulfurization absorber has certain removal effect on fine dust in flue gas

but its removal efficiency needs to be further improved. In this paper

theoretical analysis and engineering practice are combined to study the efficiency improvement of desulfurization absorption tower. The research shows that

the dust removal efficiency of the absorber can be increased by several means

such as setting guide ring and hexagonal flow equalizer with holes in the absorber

optimizing the layout of the nozzles

and installing the liquid droplets agglomeration system. Moreover

this method was verified in a power plant in Shaanxi Province. It turns out that the dust removal efficiency reached 61%

which met the requirements of ultra-low emission.
