It main y studied the inf uence of surfactant concentrationthe spraying quantity of w ater, the tow er gas ve ocity and in et dust concentration on the remova efficiency . Experimenta resu ts show that after adding 0. 05% of SDBS, when the 3 tow er gas ve ocity is 1. 5- 1. 9 m/ s, the in et du st concentration is 5 g/ m , the spraying quantity of w ater is 5- 7 L/ min , dust remova eff iciency of the system exceeded 99. 0 % .
