The main purpose of this paper was to analyze the removal characteristics of gas/particulate phase pollutants for the present system. Experimentally, we performed to estimate the pressure drop and air pollution removal efficiency with physical variables such as stage number, tube velocity, tube diameter, water spray (NH4OH), and so on. It was concluded that the pressure drop was shown below 111 mmH2O lower than that of the existing scrubber (centrifugal spray chamber, over 200 mmAq) at inlet velocity 3.46 m/s and 5 stage. The particular removal efficiency of this system was to be significantly higher at 99.8% in comparison with that of the existing scrubber for 5 stage, inlet velocity 3.46 m/s and NH4OH (aq) 300 mL/min. It was estimated that the removal efficiencies of SO2 and NO2 were 80% and 70% at system inlet velocity 2.07 m/s and NH4OH (aq) 300 mL/min respectively. Additionally, the present collection system was to be considered as an effective compact system for simultaneous removal of air pollutants (gas/particulate) due to much higher removal efficiency and appropriate pressure drop without a demister.
