Description of the Invention: [Technical Field] The present invention relates to an electrode structure of a mobile electrode type electric dust collecting device, and more particularly to a suspension on a connectorless cable body (endless cable body) The moving electrode of the moving electrode type electric dust collecting device that rotates around the discharge electrode of the plurality of dust collecting plates. [Prior Art] In order to remove the boiler exhaust gas from the thermal power station or the dust in the various furnace exhausts, a mobile electrode type electric dust collecting device disclosed in Japanese Laid-Open Patent Publication No. WO 01-0224. Fig. 4 is a perspective view showing a schematic configuration of a moving electrode used in such a moving electrode type electric dust collecting device. Between the pair of drive sprocket wheels 1 disposed at the upper portion and the pair of driven rollers 2 disposed at the lower portion, the pair of jointless chains 3 and 3 which are jointless cables are rotatably mounted . The rectangular dust collecting plate 4 is coupled by the intermediate portion 5 of the side edge thereof and is mounted between the pair of jointless chains 3, 3. The plurality of dust collecting plates 4, 4 are arranged in the chain rotating direction. .. The shaft 6 of the drive sprocket 1 is rotated by a drive mechanism (not shown), and the rotation of the shaft 6 is transmitted to a plurality of dust collecting loops integrally formed on the drive sprocket 1 to the jointless chain 3, 3'. The electrode plate 4' 4. is rotationally moved around a discharge electrode (not shown). Fig. 5 is a view showing the arrangement of the lower portion of the movable electrode 10, and the dust collecting plate 4 suspended on the jointless chain 3 and lowered is turned in a u-shape at the position of the driven roller 2, and is turned up. At a position where the dust collecting plate 4 after the rising is held, a rotating brush 7 is disposed for each lane of the moving electrode 10. Rotating brush
2189-863 5-PF 5 1361725 7的上方配設放電極8。在集塵極板4於放電極 沿上下方向移動期間，排氣中的灰塵由於來自放^上 電晕放電而帶電，被捕集到各集塵極板4的表面。^ 塵極板4通過配置有旋轉電刷7的位置:八 主工， 於集塵極 孜4表面上的灰塵被旋轉電刷7剥離、去除。 即，在這種移動電極式電性集塵裝置中， 重福；隹分·+々 下知作被 仃.在各集塵極板4於放電極8所存在的上 空間中移動期間’灰塵被捕集到各集塵極 - A N衣由，該 集塵極板4下降並在從動報2的位置U形轉向，轉為 時，由旋轉電刷7剝離、去除附著於集塵極板4表面上的 灰塵。根據這種構成’每當集塵極板4通過旋轉電刷 附著於集塵極板4表面上的灰塵都確實地被去除，集塵極 板4表面的清潔度得以恢復。因此，可將被捕集且堆積於 集塵極板4表面上的灰塵層厚度始終維持得很薄。 、 &電性集塵裝置的集塵性能受捕集到的灰塵之電阻率的 影響大。尤其是灰塵之電阻率高達1〇l2Qcm以上時，若 積於集塵極板表面上的灰塵層厚度達到規定值以上，則會 發生逆電離現象，集塵性能急劇下降。移動電極式電性^ 塵裝置由於可如上所述將被捕集且堆積於集塵極板4表面 上的灰塵層厚度始終維持得很薄，所以難以發生逆電離現 象。因此，這種移動電極式電性集塵裝置主要用於包含言 阻抗灰塵的排氣中。 在移動電極10中，如圖4所示，包含灰塵的被處理氣 體從箭頭A的方向流入，以平行於集塵極板4的流向，通2189-863 5-PF 5 1361725 7 is equipped with a discharge electrode 8 above. During the movement of the dust collecting plate 4 in the vertical direction of the discharge electrode, the dust in the exhaust gas is charged by the corona discharge, and is collected on the surface of each of the dust collecting plates 4. ^ The dust plate 4 passes through the position where the rotary brush 7 is disposed: eight main workers, and the dust on the surface of the dust collecting electrode 4 is peeled off and removed by the rotary brush 7. That is, in such a moving electrode type electric dust collecting device, the weight is reduced; the 隹 minute·+ 々 is known as the 仃. During the movement of the dust collecting plate 4 in the upper space in which the discharge electrode 8 exists, 'dust It is trapped in each dust collecting pole - AN clothes, the dust collecting plate 4 is lowered and turned in a U shape at the position of the follower 2, and when it is turned, it is peeled off by the rotating brush 7 and removed and attached to the dust collecting plate 4 dust on the surface. According to this configuration, the dust adhering to the surface of the dust collecting plate 4 by the dust collecting plate 4 by the rotating brush is surely removed, and the cleanliness of the surface of the dust collecting plate 4 is restored. Therefore, the thickness of the dust layer trapped and accumulated on the surface of the dust collecting plate 4 can be kept thin at all times. The dust collection performance of the &electric dust collector is greatly affected by the resistivity of the trapped dust. In particular, when the resistivity of the dust is as high as 1 〇 12 sec or more, if the thickness of the dust layer on the surface of the dust collecting plate reaches a predetermined value or more, the reverse ionization phenomenon occurs, and the dust collecting performance is drastically lowered. The moving electrode type electric dust device is difficult to cause reverse ionization since the thickness of the dust layer which is trapped and accumulated on the surface of the dust collecting plate 4 can be kept thin as described above. Therefore, such a mobile electrode type electric dust collecting device is mainly used in an exhaust gas containing impedance dust. In the moving electrode 10, as shown in Fig. 4, the gas to be treated containing dust flows in the direction of the arrow A to be parallel to the flow direction of the dust collecting plate 4,

Move the electrode 1 〇 υ Ύ and the dust is removed and cleaned: The gas is discharged in the direction of the arrow Β. The dust collection rate largely depends on the time elapsed when the helium gas passes through the area where the electrode 1G is moved. If the residence time of the gas to be treated is short, the deer rate is low, and if the residence time of the gas to be treated is ', the dust collection rate is high. In the case where the flow rate of the gas to be treated is constant, the larger the width of the moving electrode 10 shown by the dimension L in the drawing, the longer the residence time of the gas to be treated is. Therefore, in order to increase the dust collection rate, it is sufficient to increase the width of the movable electrode 1 ( (in other words, the length of the dust collecting plate 4) as much as possible. That is, if the width of the movable electrode 10 is excessively increased, a practical threshold is generated. Fig. 6A is a schematic side view showing the moving electrode 1 该 for explaining the problem. That is, in order to reduce the cost, it is necessary to reduce the weight of the dust collecting plate 4, and in order to make the brush cleaning effect of the rotating brush 7 effective, it is necessary to form the dust collecting plate into a thin plate shape as much as possible. Therefore, if the length of the thin (four) plate 4 is excessively increased, as shown in Fig. 6, when the dust collecting plate 4 is at the position of the upper drive wheel 1 or the lower driven roller 2, the U-turn is made. At this time, the dust collecting plates 4A, 4B in the horizontal state have a problem of excessive bending. If the bending becomes large, a large bending stress is generated on the electrode plate itself to cause plastic deformation. If the plastic deformation gradually becomes larger, the coupling portion 5 is also adversely affected, and the dust collecting plate 4 is detached from the jointless chain 3, or the jointless chain 3 and the driving sprocket i are not combined. When the light is combined, the operation is not smooth, and the distance from the discharge electrode is changed to induce a spark.
