초록
The main object of this study was to investigate the collection characteristics of wet-type cyclone with wall cavity. The experiment was executed to analyze the characteristics of pressure drop and collection efficiency for the present system with the experimental parameters such as water spray, water spray type, inlet velocity etc. In results, for the present system of wet-type, the pressure drop represented 35 mmH2O, while in dry-type 33 mmH2O showing lower 6% at =21 m/s. In case of =21 m/s and water spray 200 mL/min, the collection efficiency of the present system became significantly higher as 96.8% comparing to that of the conventional wet-type scrubber. Additionally, for 200 mL/min, SO2 removal efficiencies decreased with the increment of inlet velocity representing 75.0, 62.5, 50.0%, at =6, 9, 12 m/s, respectively.
