Embodiment Construction

[0029] figure 1 It is a schematic perspective view showing the first embodiment of the moving electrode of the electric dust collector of the present invention. A pair of endless chains 24 , 24 is rotatably stretched between a pair of driving wheels 20 , 20 arranged on the upper side and a pair of driven rollers 22 , 22 arranged on the lower side. A plurality of rectangular dust-collecting pole plates 26, 26, . . . are connected to a pair of endless chains 24, 24 at their upper end positions so as to be rotatable around a horizontal axis by a connecting portion 28. Also, for the sake of illustration, figure 1 The middle part of the dust-collecting electrode plate 26 is omitted from the illustration.

[0030] Each driving wheel 20, 20 is supported by a cantilever shaft 30, 30 from outside the moving area of ​​the dust collecting plate 26, 26, and each is rotationally driven by a driving mechanism 32, 32, respectively. The rotation of the driving wheels 20, 20 is transmitte...

Abstract

The present invention is directed to increase the width of each dust collecting electrode plate, decrease the number of parts, and allow the structure for connecting the dust collecting electrode plate to the circular restis to be compact. A mobile electrode of an electric dust collector comprises a pair of driving wheels(20)positioned on the upper side, a pair of driven wheels(22)positioned on the lower side, a pair of annular chains(24)for connecting the driving wheels(20)and the driven wheels(22), and a plurality of dust collecting electrode plates(26)which is connected to the pair of annular chains(24)and rotatablely moves surrounding the discharge electrode, wherein each dust collecting electrode plate(26)is connected, in a free rotation fashion and with respect to the annular chains(24), on the upper position of each dust collecting electrode plate, at the same time, the driving wheels(20)is supported by the cantalever shaft(30)outer side of the moving area of the dust collecting electrode plate(26).

Description

technical field [0001] The present invention relates to a moving electrode of an electrical dust collecting device, in particular to an electrical dust collecting device in which a plurality of dust collecting pole plates connected to an annular cord-like body (endless cord bar) rotate and move around a discharge electrode Move the electrodes. Background technique [0002] In order to remove dust from boiler exhaust gas of a thermal power station or various furnace exhaust gases, a moving electrode type electric dust collector as disclosed in JP-A-2001-246284 is used. Figure 6 It is a perspective view showing the schematic structure of the moving electrode used in this kind of moving electrode type electric dust collector. A pair of endless chains 3, 3 is rotatably stretched between a pair of driving sprocket wheels 1 arranged at the upper part and a pair of driven rollers 2 arranged at the lower part. A plurality of dust collecting pole plates 4, 4, ... are connected betw...
