ものである。The collector of the first conventional example is the most general type of aluminum parallel plate type, and as shown schematically in FIG. 15, a high-voltage side electrode 102 connected to the positive electrode (high-voltage) side of a high-voltage power source 101. The high voltage side electrode 102 and the dust collecting electrode 103 are both aluminum flat plates in a structure in which the dust collecting electrodes 103 connected to the negative electrode (earth) side are alternately arranged in parallel.

When the positively charged particles are guided by, the charged particles are collected by the negative potential dust collecting electrode 103.

ルムでラミネートしたものである。In the conventional collector of the second example, as schematically shown in FIG. 16, two high voltage side electrodes 202 and 203 connected to the positive electrode (high voltage) side of a high voltage power source 201 are arranged in parallel,
A high voltage power supply 20 is provided between the two high voltage side electrodes 202 and 203.
1 has a structure in which a corrugated dust collecting electrode 204 connected to the negative electrode (earth) side is provided, and the two high-voltage side electrodes 202 and 203 have surfaces laminated with a resin film made of an insulating resin. Is.

になる。In principle, the second conventional collector as described above is also the same as the first collector described above. That is, in the conventional collector of the second example, the high-voltage side electrode 20
When the positively charged particles are guided by the ionizer into the electric field generated in the space between the electrodes due to the voltage applied between the electrodes 2, 203 and the dust collecting electrode 204, the charged particles Will be collected by the dust collecting electrode 204.

ために高圧側と集塵側との電極間の印加電圧を下げれば

の低下を期たすことになるという問題が生じる。However, in the case of the conventional collector of the first example, when conductive dust is mixed in the charged particles guided to the collector, a spark occurs between the electrodes on the high pressure side and the dust collecting side. As a result, there is a problem that unpleasant sound and light are generated, and in some cases, the unpleasant sound and light are continuously generated. In addition, if the applied voltage between the electrodes on the high-voltage side and the dust collecting side is reduced in order to suppress the occurrence of sparks, the electric field strength between the electrodes will decrease, and the collection efficiency at the dust collecting electrode will be reduced. The problem arises.

ある。On the other hand, in the conventional collector of the second example, since the insulating resin film is formed on the dust collecting electrode, the occurrence of sparks between the electrodes on the high pressure side and the dust collecting side is prevented. can do. However, since the dust collecting electrode is arranged between the high voltage side electrodes, many contact points exist between the high voltage side electrode and the dust collecting electrode. In this case, since the high voltage side electrode is grounded at the contact point, a strong electric field is generated inside the insulating resin film at the grounding part of the dust collecting electrode with the high voltage side electrode, and the withstand voltage of the insulating resin film is increased. Dielectric breakdown occurs when is low, for example due to pinholes or fouling. Then, when this dielectric breakdown occurs, there is a problem that the high voltage side and the dust collecting side are short-circuited and the collector stops functioning.

D is also deposited on the surface of the
3 gets dirty. If moisture is added to this dirt, the electrical resistance will decrease, leading to the progress of a dirty state, and the surface of the insulating resin film will eventually become equal to the ground potential. In this case, the dust collection space is surrounded by the ground, the electric field disappears, and the dust collection function is stopped.

Then, the charged dust particles are collected by the dust collector provided in the subsequent stage.

FIG. 21 is an explanatory diagram showing a procedure for forming a screw hole in the insulator 302. When the insulator 302 is molded by the mold 501, the insert screw 503 is inserted inside the insulator 302. As a result, a female screw is formed inside the insulator 302. However, in such an inserting method, as shown in FIG. 22, the position of the screw hole 504 after the assembling is separated from the insulator end face, and for example, the distances L1 and L2 exist, which makes it difficult to fix the screw. I will end up. In addition, the additional machining of the screws is difficult, and the problem of forgetting to insert the insert screw 503 occurs.

Even if dust or dirt is accumulated on the high voltage electrode 7 and a leak current is generated from the high voltage electrode 7 to the ground electrode 1 through the insulator 5, since the insulator 5 and the high voltage electrode body 3 are not in contact with each other, a voltage drop occurs in each high voltage electrode 7. Does not occur, the surface potentials of all the high-voltage electrodes 7 become equal, and stable dust collection performance can be obtained. It should be noted that the insulator 5 and the high-voltage electrode body 3 may come into contact with each other as long as the performance is not so affected.

In other words, when the device becomes large, it is difficult to integrate a large number of high voltage electrodes 7 to form the high voltage electrode body 7 as in the first embodiment. Further, when the high-voltage electrode 7 and the ground electrode 1 are opposed to each other, it is desirable that the interval between them is substantially constant. The dust efficiency may decrease. Therefore, by combining a single high-voltage electrode 7 as in the second embodiment, the structure can be simplified and the distance between the high-voltage electrode 7 and the ground electrode 1 can be made substantially constant.

になる。FIG. 6 is a block diagram of a dust collector according to the third embodiment of the present invention. This embodiment is different from the first embodiment in that the power feeding body 4 supporting the high voltage electrode body 3 is U-shaped in contrast to the U-shaped in the first embodiment.
That is, the entire periphery of the high voltage electrode body 3 is surrounded by the power feeding body 4. With such a configuration, the surface potential of the high voltage electrode body 3 can be made more uniform. As a result, for example, as shown in FIG. 7, dust 32 is accumulated between the high-voltage electrode 7 and the ground electrode 1 or a bridge 31 is formed due to use over time, and even when a leak current flows, the surroundings of the high-voltage electrode body 3 can be reduced. By supplying power from the whole, it becomes possible to suppress a change in surface potential.
