<p>PURPOSE:To make the titled apparatus small-sized and to increase the dust collection efficiency in an electric precipitator by using dust collecting electrodes to increase the particle concn., sucking the waste gas of the part which has become large in the particle concn. to an outer part and collecting it with other dust collector. CONSTITUTION:Dust is introduced into electrodes 9 under test as dispersed fine particles via a dust feeder 7 and a dust disperser 8, electrified with the corona discharge which is generated between the grounded dust collecting electrode 15 of the inside of the electrodes under test and the discharge electrodes 16 impressed with high voltage and collected to the dust collecting electrodes by means of Coulomb force. At this time, the gas contg. the dust uncollected in the inside of the electrodes under test is sucked with a duct 10 for the blow down provided to the rear stage of the dust collecting electrodes and collected with other dust collector 9''. The flow rate of air and the quantity of the sucked gas are respectively regulated with valves 13, 17 and the waste gas is discharged with an exhaust fan 14.</p> |
