  • The main purpose of this study is to analyze the collection characteristics of multi-layer multi-stage porous plate system with ionizer and dielectric-substance experimentally. The experiment is carried out to analyze the characteristics of pressure drop and collection efficiency for the present system with experimental parameters such as applied voltage, inlet velocity, stage number and inlet particle concentration, etc. In results, for multi-layer multi-stage porous plate system of inflow type, at 5 stage and $v_{in}$=2.58 m/s, the pressure drop becomes lower 15 $mmH_2O$ as 95 $mmH_2O$ than that of non-inflow type system. It is estimated that for the present system with ionizer and dielectric-substance, the collection efficiency represents 98.5% showing higher 5.2% comparing to that of multi-layer multi-stage porous plate system without ionizer and dielectric-substance at 5 stage, $v_{in}$=2.58 m/s and inlet concentration $3g/m^3$(fly ash).

  • The main object of this study is to investigate the collection characteristics of multi-layer multi-stage porous plate system experimentally. The experiment is carried out to analyze the characteristics of pressure drop and collection efficiency for the present system with the experimental parameters such as inlet velocity, tube diameter, inlet concentration, and stage number, etc. In results, the pressure drop becomes 22 to $115mmH_2O$ with increment of stage number (1 to 5) of porous plate system at tube velocity 15 m/s and tube diameter ${\Phi}8$. In case of fly ash and 5 stage, the collection efficiency becomes 90.5 to 95.7% increasing the tube velocity 12 to 15 m/s at inlet concentration $3g/m^3$ and tube diameter ${\Phi}8$. Additionally, it is estimated that the collection efficiencies of 5 stage are 94.3, 95.6 and 99.1% for fly ash, steel dust and based power, respectively (${\Phi}8$ tube, $V_t$ = 12m/s, inlet concentration $3g/m^3$).

  • The main object of this study is to investigate the Dust Collection Characteristics of multi-layer multi-stage porous plate system with polarization charging mechanism, experimentally. The experiment is carried to analyze the characteristics of pressure drop and collection efficiency for the present system with the experimental parameters such as applied voltage, inlet velocity, inlet concentration and stage number, etc. In results, the pressure drop becomes 18 to $134mmH_2O$, with increment of stage number (1 to 5) at inlet velocity $v_{in}$ = 3.11 m/s ($v_t$ = 18 m/s) and inlet concentration 3 g/m3 for inflow current. In case of both applied voltage 0 kV and non-inflow current, the collection efficiency of 5 stage is 92.5% at $v_{in}$ = 2.58 m/s ($v_t$ = 15 m/s), while it is estimated that the collection efficiency becomes about 6% higher than that of 0 kV and non-inflow as 98.5% at $v_{in}$ = 2.58 m/s for both alternating polarization charge (applied voltage 2.5 kV) and inflow current system.
