The mechanical filter system, which is one of the systems for capturing particles by using mechanical force, has a level of 0.3 micron at the level of a ULPA filter used in a clean room of a semiconductor factory, for example. It exhibits a very high dust collection efficiency of over 99% even for extremely fine particles, but it has poor breathability in principle and exhibits a very high pressure loss characteristic. In addition, this very high pressure loss is generally used. In order to reduce to a possible pressure loss value, it must be pleated to have a thickness in the downstream direction of the gas flow or to have a large cross-sectional area through which the gas flow permeates.
As a result, it becomes a large dust collecting part, and the mesh of the mechanical filter is dense in order to obtain a high dust collecting efficiency.For example, an attempt was made to remove dust trapped by a method such as ultrasonic cleaning to regenerate it. Even if the mechanical filter is used, the fine mesh that is the life of the mechanical filter will spread and the dust collection efficiency will be significantly reduced, so it is almost impossible to reuse the mechanical filter, and therefore it will be discarded when the mechanical filter reaches the end of its useful life. However, it has disadvantages such as high running cost as a result.

On the other hand, the electrostatic precipitator using electrostatic force is
Although the pressure loss to the gas flow is low in principle, the dust collection efficiency is not necessarily high compared with a ULPA filter and the like. At present, various measures have been made to improve the dust collection efficiency. First, a general example of a conventional electrostatic precipitator is shown in FIG. In FIG. 2, the discharge electrode 1 is arranged parallel to the dust collecting electrode 2 and the gas flow 6. Also,
A needle-shaped needle end portion 3 is provided at the tip of the discharge electrode 1. When the negative side of the power source 4 is connected to the discharge electrode 1, the positive side is connected to the dust collecting electrode 2 and the ground 5,
The electric field is concentrated on the needle end portion 3 of the discharge electrode 1, the air insulation near the needle end portion 3 is destroyed, and a negative corona discharge is generated. The particles that have entered this space from the upstream side of the gas flow 6 pass through the negative ion space generated by the corona discharge, and thus are negatively charged by a mechanism such as electron attachment or electron impact. And the particles are the charge that they have and the discharge electrode 1
Due to the action of the electric field created by the dust collecting electrode 2, the Coulomb force is received, and it is guided to the dust collecting electrode 2 and trapped.

In this general dust collecting method, as the Deutsche formula shows, the larger the electric field strength formed between the discharge electrode 1 and the dust collecting electrode 2, and the larger the area of the dust collecting electrode 2. The more the dust collecting effect is improved. However, even when the electric field strength is increased, the upper limit is the spark discharge inception voltage, and since a safety factor is usually taken as a considerable amount, the improvement of the dust collection efficiency by increasing the electric field strength cannot be obtained as expected. . Further, in the case of FIG. 2, in the method of increasing the area of the dust collecting electrode 2,
It is necessary to extend the dust collecting electrode 2 to the downstream side of the air flow, and there is a drawback that the dust collecting portion becomes large.

Japanese Unexamined Patent Publication No. 1-310751 is an invention in which a conductive foam having bubble-like holes or a conductor entwined with metal fibers is arranged on the downstream side of a charging portion, and also Japanese Unexamined Patent Publication No. 2-10751. Japanese Patent No. 211262 is an invention in which a conductive organic polymer porous material is arranged. Conductive foam on the downstream side of the charging section,
In the case where the conductive organic polymer porous material is arranged, each has a three-dimensional structure, and in principle, the ventilation resistance is considerably increased. Therefore, for example, when the particle size to be collected is about 0.3 micron, The pressure loss cannot be reduced unless the pore size is set to be considerably larger than the particle size. Therefore, in order to ensure sufficient dust collection efficiency, it is necessary to extend these porous bodies in the gas flow direction. Specifically, JP-A-2-2112
As shown in FIG. 2 of Japanese Patent Laid-Open No. 62-62, in the case where the hole diameter is 2 mm, the dust collecting effect is remarkably exhibited.
This is the case when the thickness is 0 mm or more. Further, in the case where a conductor entwined with metal fibers is arranged downstream of the charging section, the pore diameters become uneven as described in JP-A-57-150457, and when the pore diameter is reduced, Since the pressure loss increases in principle, it is necessary to increase the hole diameter to extend the metal fiber conductor in the gas flow direction.

FIG. 3 (a) is a schematic view of the dust collecting system of the present invention, and FIG. 3 (b) is an enlarged view of only the dust collecting portion of FIG. 3 (a). The gas flow 6 is a flow of gas to be processed by the air cleaning device generated by, for example, a fan, and the gas flow 6 on the upstream side of the dust collecting unit contains dust to be processed.
The dust carried on this gas flow 6 is first discharged to the discharge electrode 1.
And passes through a charging portion constituted by the counter electrode 7 and is charged. Here, in FIG. 3A, the discharge electrode 1 is a wire electrode, and the counter electrode 7 is a flat plate electrode.
A negative high voltage is applied by the charging unit power supply 4b to the counter electrode 7, and the opposite electrode 7 is applied with a positive polarity which is the opposite polarity by the charging unit power supply 4b and is connected to the ground 5. In this charging part, a negative corona discharge is generated from the discharge electrode 1,
The dust particles contained in the gas flow 6 passing therethrough are negatively charged (hereinafter, the charged dust particles are referred to as charged particles 9).
On the downstream side of the gas flow 6 of the charging section, there is the dust collecting section of the present invention,
The structure is such that the collecting electrode 8 that is permeable to the gas flow 6 has a flat plate of mesh-shaped metal that is orthogonal to the gas flow 6 to form the collecting electrode gas flow transmitting portion 8a, and is parallel to the gas flow 6. A flat plate of metal is arranged on the above to form the collecting electrode gas flow non-permeable portion 8b,
Inside the collection electrode 8, a repulsion electrode 12 having an elliptical cross section is provided.
Is arranged. When the charged particles 9 reach the dust collecting portion according to the vector given by the gas flow 6, the collecting electrode gas flow transmitting portion 8a
Since the gas stream 6 is permeable, the charged particles 9 a contained in the gas stream 6 ride on the gas stream 6 and enter the inside of the collection electrode 8. Here, since the collecting electrode 8 is given a positive polarity opposite to the negative polarity of the charged particles 9a by the dust collecting part power source 4a, the charged particles 9a are also generated outside the collecting electrode 8 by the Coulomb force. However, the force acting between the charged particles 9a and the collecting electrode 8 is weak in this region, and the charged particles 9a are trapped only very slightly.

Will exist. This repulsion electrode upstream region 10a
Then, the gas flow 6 is influenced by the repulsion electrode 12 and is deflected toward the collecting electrode gas flow non-permeable portion 8b. Since the vector of the charged particles 9b given from the gas stream 6 also follows the flow of the gas stream 6, the charged particles 9b form the vector 11b given from the gas stream 6, the collection electrode 8 and the repulsion electrode 12 as shown in FIG. 3b.

Here, the characteristics of the action of trapping the charged particles 9b in the repulsion electrode upstream region 10a will be described. The repulsion electrode 12 deflects the advancing direction of the gas flow 6 so that the collection electrode 8 and the repulsion electrode 12 are separated from each other. That is, the charged particles 9b are directed to the inside of the collecting electrode 8 together with the electric field to be formed so that the collecting electrode 8 can easily trap the charged particles 9b.

The charged particles 9b that have not been trapped in the repulsive electrode upstream region 10a are carried further downstream by the gas flow 6 and are near the center line of the repulsive electrode 12 and the normal to the gas flow 6. A region (hereinafter, this region is referred to as a region 10b near the repulsion electrode) is reached. In the region 10b near the repulsion electrode, the charged particle 9c is represented by a vector 11c obtained by combining a vector 11b given by the gas flow 6 and a vector 11a given by the electric field formed by the collection electrode 8 and the repulsion electrode 12.

The charged particles 9c that are not trapped in the region 10b near the repulsion electrode are carried further downstream by the gas flow 6 from the line that is the center line of the repulsion electrode 12 and is the normal line of the gas flow 6. The area reaches the downstream side area (hereinafter, this area is referred to as the repulsion electrode downstream side area 10c). In the region 10c on the downstream side of the repulsion electrode, the charged particle 9d is a force represented by a vector 11c obtained by combining a vector 11b given by the gas flow 6 and a vector 11a given by an electric field formed by the collection electrode 8 and the repulsion electrode 12. Upon receipt, it goes to the inside of the collection electrode 8 and is trapped inside the collection electrode 8. However, in the region 10c on the downstream side of the repulsion electrode, the vector 11b given from the gas flow 6 is generated.
Then, the directions of the vector 11a given by the electric field formed by the collection electrode 8 and the repulsion electrode 12 become substantially equal, the two combined vectors 11c received by the charged particles 9d become large, and the mobility of the charged particles 9d becomes large. . Therefore, the collection efficiency of the charged particles 9 is not necessarily higher in the repulsion electrode downstream region 10c than in the repulsion electrode upstream region 10a and the region 10b near the repulsion electrode described above. However, the downstream area 10c of the repulsion electrode also has the function of improving the collection efficiency of the entire dust collecting portion. Due to the mechanism in each region as described above, the dust collecting portion according to the present invention can obtain extremely high dust collecting efficiency.

In an air purifying apparatus having a charging section on the upstream side of the gas flow and a dust collecting section on the downstream side, the dust collecting section has a columnar shape having the same polarity as the charging polarity of the charging section or one of the inside thereof. A repulsion electrode having a hollow part or all is provided, and the repulsion electrode is gas-permeable around the repulsion electrode through a gap and has a polarity opposite to the charge polarity of the charging part. A dust collecting portion having a collecting electrode disposed around the repulsive electrode, and a dust collecting portion in which the outer shape of the collecting electrode and the repelling electrode are similar to each other and the center of the repelling electrode and the center of the collecting electrode coincide with each other. , The repulsion electrode is a cylinder or a cylinder in which a part or all of the inside is hollow, and the collecting electrode is a concentric cylinder, and the repulsion electrode is a cylinder or a part or all of the inside. Is a hollow cylinder,
When the gas flow is allowed to pass through the repulsion electrode of the dust collecting part in which the collection electrode is a square pole, the gas flow 6 flows without being deflected by the repulsion electrode 12, but the charged particles 9 are charged. 8 and the repulsion electrode 12 make it extremely difficult to pass through the inside of the repulsion electrode 12 due to the action of the electric field formed by the repulsion electrode 12, and receive a force toward the collection electrode 8. Here, considering the flow velocity of the gas flow 6 inside the collection electrode 8, the repulsion electrode 1
When 2 does not permeate the gas flow 6, the cross section through which the gas flow 6 can pass becomes small in the region 10b near the repulsion electrode, and as a result, the flow velocity of the gas flow 6 in this region increases. As described above, the force exerted by the charged particles 9 is due to the gas flow 6 and the electric field acting between the collection electrode 8 and the repulsion electrode 12, and the force exerted by the gas flow 6 in the region 10b near the repulsion electrode is not always charged. It does not work in the direction of trapping the particles 9, but rather works in the direction of blocking the trap. Therefore, in the region 10b near the repulsion electrode, it is rather desirable that the flow velocity of the gas flow 6 be low, and the gas flow 6
Permeate the inside of the repulsion electrode 12 to reduce the velocity of the gas flow 6 in the region 10b near the repulsion electrode, so that the collection efficiency of the charged particles 9 increases in the region 10b near the repulsion electrode, and therefore high dust collection is achieved. An efficient dust collecting part can be realized. Also,
According to this method, it is possible to reduce the pressure loss of the dust collecting portion.

Further, in the dust collecting part according to the present invention described above, a part or all of the collecting electrode is provided in a region downstream of the center line of the repulsion electrode and the normal line of the gas flow to the gas flow. If removed, it is possible to reduce pressure loss while maintaining high dust collection efficiency, and at the same time reduce the number of parts that make up the dust collection unit, thus reducing the weight and cost of the dust collection unit. it can. This is because the direction of the gas flow 6 and the repulsion electrode 1 in the region 10c on the downstream side of the repulsion electrode are as described above.
The direction due to the action of the electric field acting between 2 and the collection electrode 8 becomes almost equal, and the mobility of the charged particle 9 increases due to these two forces, so that the repulsion electrode upstream region 10
a, since the dust collection efficiency of the charged particles 9 is not necessarily higher than that of the region 10b near the repulsion electrode, a relatively high dust collection efficiency can be obtained without collecting the charged particles 9 in this region. Is.
