Experimental Study On Dust Removal Efficiency Of Electrostatic Precipitation For Biomass Flue Gas

In view of the problem of electrostatic dust removal of biomass flue gas, the performance of line type high voltage electrostatic precipitator is systematically studied. The effects of the form of the electrode line, the size of the operating voltage (V), the voltage polarity and the inlet flue gas concentration (rho(1)) on the dust removal efficiency (eta) were obtained. The results show that the dust removal efficiency of the T-shaped line is higher than that of the circular line. The efficiency of dust removal increases first and then tends to be constant with the increase of the voltage. Under the same conditions, the negative voltage efficiency is higher than the positive voltage's. The efficiency of dust removal decreases with the increase of the inlet concentration.
