Abstract：Water mist charging and solution active treatment,as two kinds of efficient dust removal methods,showed good dust re-moval effect when they used independently.In order to explore the settling effect of the combined use of the two on fine dust,sodi-um dodecyl sulfate(SDS)surfactant was used to prepare the active solution,and copper burr ring electrode was used for corona char-ging.Under the background of micron droplet field charging,the charging effect of micron active droplet and its wettability to an-thracite were investigated.The results show that the active solution is more sensitive to electric field than pure water.Water mist charging and solution activity treatment showed synergistic effects on enhancing droplet fragmentation,reducing droplet size and en-hancing solution wettability.Compared with ordinary water mist,micron-charged active water mist has higher capture efficiency for anthracite dust,and sedimentation efficiency for total dust and respirable dust is up to 91.77%and 90.45%.
