Abstract

PURPOSE:To obtain an electric dust precipitator which is capable of generating a sufficient discharge current even by low pulse voltage, by constituting so that discharge electric wires placed in parallel on a dust precipitating plate are formed by 1 group 2 of pieces, and the potential of one discharge electric wire in each group is different from the potential of the other discharge electric wire. CONSTITUTION:Between dust precipitating plates 1, 1 placed opposingly in parallel, discharge electric wires 2 of each group consisting of 2 discharge electric wires 2A, 2B placed in parallel are set at prescribed intervals. Said each discharge electric wire 2 is both fixed to a conductive supporting frame 3 by both its ends, and also the discharge electric wire 2B of each group is wound round a bobbin 3A fitted to the frame 3 by its one end, and is fixed to the frame 3. Also, to the frame body 3, an electric power supplying source of a DC power supply 4 whose one terminal is grounded is connected, and also it is connected through a capacitor 6 to an electric power supplying terminal of a pulse electric power supply 5 whose one terminal is grounded. Subsequently, between the grounded plate 1 and the discharge electric wires 2, voltage which is superposed a pulse to DC is applied, and in the wires 2A, 2B of each group, a large voltage difference is generated by a reactor formed in one said wires, so that a discharge current is made to flow more than the case when pulse voltage is applied to each discharge electric wire provided under the same condition.
