In an electrostatic precipitator comprising a vertical casing defined by inner and outer walls 4, 3 and divided into sector-shaped chambers 32 through which dust-laden gas is caused to flow upwardly over complementary electrodes 16, 21 and wherein each of the chambers 32 is substantially disconnected separately from the gas flow by means of a dust-discharge duct 6 rotated in resilient sealing engagement with the lower end of the casing and a sealing plate 7 rotated in partial sealing engagement with the upper end of the casing, the assembly 6, 7 being rotated step by step in synchronism with electric-supply cut-off means for the associated electrodes 16, 21, rapping devices 18, 23 are provided for the electrode assemblies 16, 21 respectively operable to dislodge dust therefrom into the duct 6 during the cleaning cycle of each chamber. As shown the duct 6 leads into a hopper 10 and during each cleaning cycle, clean air from the casing outlet 2 is drawn into the chamber being cleaned through the substantially sealed upper end of the chamber to flush any fine dust from the electrodes into the hopper 10. This flushing air flow is induced by a fan 14 which draws the air into a secondary dust collector 12 via a pipe 11 from the hopper 10, the air being eventually discharged back into the dust-laden gas at the casing inlet 1. The rotating assembly 6, 7 may be duplicated on diametrically opposed sides the casing. The electrodes 16 may be anodes of tubular or plate form supported on insulators 17a resting on the rapping devices 18, the cathodes 21 also being supported at their upper ends on insulators 20a and being connected together at their lower ends by a spring mounted and insulated spacer 22. Switching of the electrode supply current may be effected by means of saturable reactors.,下面是Electrostatic precipitator专利的具体信息内容。
