초록
The main object of this study is to investigate the collection characteristics of wet-type rotating porous disk system experimentally. The experiment is carried out to analyze the pressure drop and collection efficiency for the present system with the experimental parameters such as system inlet velocity, stage number, tube diameter, inlet concentration, etc. In results, for the present system, at 5 stage and =1.8 m/s, the pressure drop becomes significantly lower as 64 mmH2O in comparison with that of the conventional wet type scrubber (Venturi scrubber, over 250 mmH2O). The collection efficiencies increase with higher inlet velocity showing 92, 95.7, 98.4%, while SO2 removal efficiencies decrease with increment of inlet velocity as 80, 65, 50% at =1.08, 1.44, 1.8 m/s and tube diameter =10 mm, respectively. The present system is to be considered as an effective compact system for a simultaneous removal of particle/gas phase pollutants from marine diesel engines.
