リアルシールとして機能する。Dust in the exhaust gas enters the dust collector from the inlet, is applied with a high electric field inside, and adheres to the dust collecting electrode of the dust collecting electrode 4 . The gas is discharged to the outside from the outlet as clean gas. The dust adhering to the dust collecting electrode of the electrode 4 is timely brushed off by a hammer ring or the like and stored in a hopper 5 arranged below the dust collector. The dust stored in the hopper 5 is transported to another yard by a vacuum type or pressure type ash transport mechanism (not shown). A seal plate 6 is attached to the hopper 5 to prevent the exhaust gas from making a short pass, and functions as a material seal by leaving dust in the hopper.
従来の電気集じん装置は、ダストを貯えるホッバ５を必
要とするので、可成り大きな設置スペースが必要であり

する。その結果、必然的に電気束じん装置全体が大型で
複雑な構造を有するものとなり、製作に要する材料費、
建設費、付帯工事費等が嵩む。Since the conventional electrostatic precipitator requires a hobber 5 for storing dust, a considerably large installation space is required, and in particular, a long and robust pedestal 2 with sufficient height is required. As a result, the entire electric bundle device inevitably becomes large and has a complicated structure, resulting in lower material costs and lower production costs.
Construction costs, incidental work costs, etc. will increase.
そこで本発明は、性能的には従来のものに比して何等遜
色のない性能を有し、かつ島さが著しく低く、装置全体

たダストを、集じん器外へ排出する排出機構を設ける。The present invention has taken the following measures in order to solve the above problems and achieve the objectives. That is, a dust scraping body is provided between the electrode of the electric dust collector and the bottom plate from which dust is brushed off, and the dust scraping body is driven so that the dust stains a specific part of the bottom of the dust collector. A drive mechanism is provided. A discharge mechanism is provided to discharge the dust collected by the dust collector to the outside of the dust collector.

およびエアシリンダー１６の方向切換を行う。First, the configuration will be explained. As shown in FIG. 3, a chino 19 is stretched between the sprockets 12 on both sides of the electric dust collector bottom plate 21, and a scraping plate 14 is attached to this. The installation of the scraping plate 14 to the chino 19 is shown in Fig. 4(a) (
As shown in b), the upper end of the scraping plate 14 is connected to the chain 19, and the lower end is free. This scraping plate 14 is placed in the gap between the electrode section 10 and the bottom plate 21. As shown in FIG. 3, a screw conveyor 20 as a discharge mechanism is attached to the center of the bottom plate 21. Further, two guide rails 17 are passed through the bottom plate 21 in a direction perpendicular to the scraping plate 14. As shown in FIG. 7, this rail 17 has pieces with different angles by 90' from the center, and has a crank connected to the connecting rod 18 at one end. This connecting rod 1
8 by the air cylinder 16, the guide rail 17 is rotated by 90 degrees. A limit switch is provided at the position where the scraping plate 14 reaches the right or left end, and this limit switch signal causes the motor 11 to rotate forward or reverse, and the direction of the air cylinder 16 to be switched.
次に上記の如く構成された本装置の動作を第５図および
第６図を適時参照して説明する。電極部１０で捕集され

縁部上を無理なく斜行できる。When the power is turned on, the motor 11 starts rotating forward. At this time, the air cylinder 16 is operating in one direction, and as shown in Fig. 5, the air cylinder 16 is operating in one direction, and the empty side of the guide rail 17 is horizontal, and the left ventricular side is vertical. ing. Therefore, the scraping plate 14 moves from the sky on the right side to the left side, but while moving to the center part, it moves the dust on the right side towards the center part. The scraping board 14 continues to move to the left, but since one part of the guide rail 17 in the chamber to the left of the dust conveyor 20 is vertical, the bottom surface of the scraping board 14 passes over the dust. . When the scraping plate 14 reaches the left end of the left chamber, the limit switch is activated, the guide rail 17 rotates 90 degrees, and the motor 11 also rotates in reverse. Therefore, as shown in FIG. 6, the scraping plate 14 scrapes up the left empty dust to the center. When the scraping board 14 reaches the right end of the right chamber, the guide rail 17 rotates 90'' again, and the motor 11 also rotates in reverse again. Therefore, it is possible to move diagonally on the vertical edge of the guide rail 17 without any difficulty.
一方、スクリューコンベア２０は連続して運転される。On the other hand, the screw conveyor 20 is continuously operated.
したがって、底板２１の中央部に集められたダストは回
収され、かつ外部へ排出される。Therefore, the dust collected at the center of the bottom plate 21 is collected and discharged to the outside.
なお必要ならば、一旦タンクで受けたのち搬送するよう

ようにしてもよい。Note that the present invention is not limited to the above embodiments. For example, in the embodiment described above, the dust is collected in the center of the bottom plate 21, but by changing the structure of one part of the guide rail 17, the dust may be collected in a portion to the right or left side.

を提供できる。According to the present invention, a dust scraping body is provided between an electrode of an electrostatic precipitator and a bottom plate from which dust is brushed off, and the dust scraping body is moved to a specific part of the bottom of the dust collector. Since a drive mechanism is provided to drive the dust to collect, and a discharge mechanism is provided to discharge the dust collected by the dust collector to the outside of the dust collector, the hopper at the bottom of the electric chamber lid is eliminated, and the mount can be extremely low,
Not only the pedestal but also the members of the superstructure need to be lightweight and minimal, making it possible to reduce material costs, construction costs, ancillary work costs, etc. In this way, it is possible to provide an electrostatic precipitator that has performance comparable to conventional ones, is extremely low in height, has a compact overall device, and can significantly reduce manufacturing costs.
