本発明は電気集塵機用フイルタの改良に係り、
その目的とするところは多目的のフイルタをより

もより高めんとすることにある。[Detailed Description of the Invention] The present invention relates to an improvement of a filter for an electrostatic precipitator,
The purpose is to create a multi-purpose filter more easily and to improve the efficiency of the dielectric filter.

も大きくなつて、電気集塵機のコンパクト化に対
して大きな障害となつていた。 Conventionally, there are two types of filters for electrostatic precipitators: those that use dielectric filters and those that use overlapping metal electrode plates. The dust is charged by passing through a charged part that causes corona discharge, etc., and a dielectric filter is placed behind it to separate the charged dust particles from the dielectric. Dust is collected on the dielectric filter by electrostatic force between the body fibers. Although there are various shapes of this dielectric filter, it generally occupies the space next to the charging section, and then a filter consisting of a breathable case containing viscous activated carbon, gas removal substance, etc. is located. A dielectric filter specifically for dust and a filter for removing odor and waste gas are installed separately, and maintenance must be performed separately.Also, since they are separate, they occupy a large space, making it difficult to install an electric precipitator. This has been a major obstacle to the miniaturization of the
又、誘電体フイルタの接地も性能維持のために

対し障害となつていた。 Furthermore, grounding of the dielectric filter is necessary to maintain performance, but conventionally, a grounding device such as a wire mesh is used for this purpose, which also poses an obstacle to miniaturization.
本発明は上記従来の欠点を解決せんとするもの
で、以下図面にもとづいてその一実施例を説明す
る。 The present invention aims to solve the above-mentioned conventional drawbacks, and one embodiment thereof will be described below based on the drawings.
第１図において、１は電気集塵機のボデー、２

その後方には荷電部４、更に後方に集塵部５があ

いる。 In Figure 1, 1 is the body of the electrostatic precipitator, 2
is an electric blower, and there is an intake hole 3 in front of it.
There is a charging section 4 behind it, a dust collection section 5 further behind it, and an exhaust hole 6 is opened at the rear of the electric blower 2.

は排気孔より吐出される。 In the above configuration, when the electric blower 2 starts to move, dust-containing air is sucked through the intake hole 3 and the charging section 4
The dust particles are charged with electricity, and the charged particles are adsorbed on a dielectric filter in the dust collecting section 5, and odor etc. are adsorbed on a gas adsorption layer such as activated carbon, and the purified air is discharged from the exhaust hole. It is discharged.

ある。 Fig. 2 shows the structure of the dust collection section, where 7 is a dielectric filter, and 8 is a granular material located in close contact with the surface of the dielectric filter 7 on the electric blower 2 side, which removes granular activated carbon or gas. Consists of substances or mixtures thereof. Reference numeral 9 denotes a breathable sheet, and the granular material 8 is clamped between the breathable sheet 9 and the dielectric filter 7. Reference numeral 10 denotes a frame body in which the dielectric filter 7, the granular material 8, and the breathable sheet 9 are adhered to each other and are integrally fixed with the periphery compressed.
１１は上記粒状体８を接地させるために設けた
接地端子で、一端が上記粒状体８に接するととも

端で外部に露出している。 Reference numeral 11 denotes a ground terminal provided to ground the granular material 8, one end of which is in contact with the granular material 8, and the other end of which passes through the frame 10 and is exposed to the outside at the lower end of the frame 10. There is.
上記構成のフイルタにおいて、粒状物８は上記
の様にそのサポートに誘電体フイルタ７を兼用す
ることにより、集塵部およびガス吸着部を一体化
することが可能で、このため、メインテナンス性
が顕著に向上する。 In the filter having the above configuration, by using the dielectric filter 7 as a support for the particulate matter 8 as described above, it is possible to integrate the dust collection part and the gas adsorption part, and therefore the maintainability is remarkable. improve.
又、通気性シート９を起毛性が大なるもので構
成すると、粒状体８の空間係止効果が期待でき、
同粒状体８のフイルタ内での偏在が防止できる。
ところで、粒状体８の固有抵抗を105Ω−cm程度
以下に押え、接地端子１１を設けると、集塵作用

ち通常の電気集塵機では、放電電流は数百μＡ程
度であり、電圧も数Kvであるので、105Ω−cm程
度の抵抗を有していても十分に電荷を除去でき
る。 Furthermore, if the breathable sheet 9 is made of a material with a high napping property, a spatial locking effect of the granular material 8 can be expected,
Uneven distribution of the same granules 8 within the filter can be prevented.
By the way, if the specific resistance of the granular material 8 is kept below about 10 5 Ω-cm and the ground terminal 11 is provided, the electric charges that are charged up on the dielectric filter 7 during the dust collection operation are gradually dissipated through the ground terminal 11. , a reduction in efficiency due to generation of a reverse electric field due to charge up of the dielectric filter 7 can be minimized. That is, in a normal electrostatic precipitator, the discharge current is on the order of several hundred μA and the voltage is on the order of several KV, so even if it has a resistance of about 10 5 Ω-cm, it can sufficiently remove charges.
このことにより、通常空気中に電荷を逃してい

誘電体フイルタに用いる誘電性繊維は、103Hzで

いて得た効率曲線Ａと誘電率2.0度のフイルタの
効率曲線Ｂ，Ｃを荷電部の能力（放電電流で代表
する）によつて描いている。 This increases the efficiency by about 10 to 20% compared to when the charge is normally released into the air, contributing to improved performance of the electrostatic precipitator. In addition, the dielectric fiber used in the dielectric filter described above has a dielectric constant of 3.0 or more at 10 3 Hz, a water absorption rate (24 hours) of 1.0% or less, is ozone resistant, and is a fiber that does not use a binder. If there is, the efficiency of the dust collection section can be further improved, and Figure 5 shows the efficiency curve A obtained using the filter of this specification and the efficiency curves B and C of the filter with a dielectric constant of 2.0 degrees for the charging section. It is depicted by capacity (represented by discharge current).
吸水率の多少は、実質的に誘電率に影響を及ぼ
し、本仕様における1.0％以下（24時間侵水後）

効率の低下は30％以内におさえることができる。
ところで、バインダーを用いると、バインダの吸

般にバインダーは溶剤等を用いる為に、吸水率が

なりやすく、実質的に吸水し易くなるため、ここ
では使用しない方が効果的である。 The degree of water absorption substantially affects the dielectric constant, which is less than 1.0% in this specification (after 24 hours of water immersion)
With this method, the reduction in dust collection efficiency can be kept within 30% even in rooms with relative humidity of 98%.
By the way, when a binder is used, the water absorption rate of the binder must of course be sufficiently low, but binders generally use a solvent, so even if the material has a low water absorption rate, it becomes porous when the solvent scatters. It is more effective not to use it here because it is easy to absorb water.
又、耐オゾン性も放電電流が増加すると、第４

う非常に大なる効果がある。 In addition, as the discharge current increases, the ozone resistance also increases.
As shown in the figure, this directly leads to an increase in ozone concentration, and materials that are severely degraded by ozone cannot be used. As mentioned above, if such a fiber structure is used, it is possible to obtain extremely high efficiency as shown in Figure 3, and even in an atmosphere with a humidity of 98%, it is possible to obtain approximately 30% humidity.
There is only a slight decrease in efficiency and there is little ozone deterioration, which is a very big effect.

ができる。 As described above, according to the present invention, it is possible to capture charged dust and remove odor or waste gas with a single filter, and there is no need for separate or large-scale equipment, which greatly improves ease of handling. can be improved.

り一層促進できるものである。 Furthermore, in the case of the present invention, even particles that are extremely difficult to hold can be reliably bonded to the dielectric filter. In addition, since the electric charge of the dielectric filter can be released through the grounding terminal that is in contact with the granular material, it is possible to maintain good dust collection performance at all times. The size of the device does not increase, and its compactness can be further promoted.
