Description

本発明は、空気中の浮遊粒子状物質を捕集し空気清浄を行うための電気集じん機に関する。   The present invention relates to an electric dust collector for collecting airborne particulate matter and cleaning the air.

従来、この種の電気集じん機は、コロナ放電を発生させ空気中の浮遊粒子状物質を帯電させる帯電部と、空気中の浮遊粒子状物質を捕集する集じん部から構成されており、例えば、特許文献１のようなものが知られている。   Conventionally, this type of electrostatic precipitator is composed of a charging unit that generates corona discharge and charges suspended particulate matter in the air, and a dust collecting portion that collects suspended particulate matter in the air. For example, the thing like patent document 1 is known.

以下、その電気集じん機について図７を参照しながら説明する。帯電部１０１は様々な形状（例えば線やトゲや針など）をした放電電極１０２と金属製の薄板からなる接地電極板１０３とが交互に積層されている。集じん部１０５は金属製の薄板からなる荷電極板１０６と金属製の薄板からなる接地極板１０７とが交互に積層されている。放電電極１０２には電源１０４から高電圧が印加され接地電極板１０３との間でコロナ放電が発生し、荷電極板１０６には電源１０４から高電圧が印加され接地極板１０７との間に電界が形成される。空気中の浮遊粒子状物質は、帯電部１０１でコロナ放電によって帯電され、集じん部１０５で電界によって接地極板１０７に付着、捕集され、空気清浄を行うものである。   Hereinafter, the electric dust collector will be described with reference to FIG. In the charging unit 101, discharge electrodes 102 having various shapes (for example, lines, thorns, needles, etc.) and a ground electrode plate 103 made of a thin metal plate are alternately stacked. In the dust collection portion 105, load electrode plates 106 made of metal thin plates and ground electrode plates 107 made of metal thin plates are alternately laminated. A high voltage is applied to the discharge electrode 102 from the power source 104 to generate a corona discharge between the ground electrode plate 103 and a high voltage is applied to the load electrode plate 106 from the power source 104 to form an electric field between the ground electrode plate 107. Is formed. The suspended particulate matter in the air is charged by corona discharge in the charging unit 101 and is attached to and collected on the ground electrode plate 107 by an electric field in the dust collection unit 105 to perform air cleaning.

大風量を処理する電気集じん機では（例えば１ユニット当たり３００ｍ3／ｍｉｎ）その処理風量から１ユニット当たりの大きさが大きくなるため、使用する接地電極板１０３、荷電極板１０６、および接地極板１０７の１枚当りの大きさが大きくなるとともに、使用枚数も多く、そのため重量が重くなっていた。 In an electrostatic precipitator that processes a large amount of air (for example, 300 m 3 / min per unit), the size per unit increases from the amount of air that is treated, so that the ground electrode plate 103, the load electrode plate 106, and the ground electrode used As the size of each plate 107 is increased, the number of used plates is large, and thus the weight is increased.

このため、出来る限り軽量化をするために、接地電極板１０３、荷電極板１０６、および接地極板１０７の厚みを薄くしたり、特許文献１のように集じん部１０５の接地極板１０７にパンチング穴１０８を設けるなどしていた。
特開平１１−０５７５３１号公報 For this reason, in order to reduce the weight as much as possible, the thickness of the ground electrode plate 103, the load electrode plate 106, and the ground electrode plate 107 is reduced, or the ground electrode plate 107 of the dust collecting portion 105 as in Patent Document 1 is used. A punching hole 108 was provided.
Japanese Patent Laid-Open No. 11-057531

このような従来の電気集じん機では、軽量化のために極板の厚みを薄くしすぎると剛性がなくなり極板同士の距離を保つことが困難となり、また、極板に穴を設けすぎると導電部分が減少し電界強度が弱まるため、いずれにしても集じん機能が低下するという課題があった。   In such a conventional electrostatic precipitator, if the thickness of the electrode plates is made too thin for weight reduction, the rigidity is lost and it becomes difficult to maintain the distance between the electrode plates, and if too many holes are provided in the electrode plates Since the conductive portion is reduced and the electric field strength is weakened, there is a problem that the dust collection function is deteriorated in any case.

また、帯電部や集じん部において火花放電が発生し、浮遊粒子状物質が可燃性の場合は温度が異常上昇し、極板などが熱により変形し耐久寿命が短くなるという課題があり、これを避けるために、印加電圧を下げたり、極板間隔を広げたりすると集じん機能が低下するという課題があった。   In addition, when spark discharge occurs in the charged part and dust collection part, and the suspended particulate matter is flammable, the temperature rises abnormally, and the electrode plate is deformed by heat and the durability life is shortened. In order to avoid this problem, if the applied voltage is lowered or the distance between the electrode plates is increased, the dust collection function is deteriorated.

本発明は、このような従来の課題を解決するものであり、集じん機能を維持しつつ、軽量化を行い、さらに火花放電の発生を抑え、温度の異常上昇を未然に防止する電気集じん機を提供することを目的としている。   The present invention solves such a conventional problem and reduces the weight while maintaining the dust collection function, further suppresses the occurrence of spark discharge, and prevents the temperature from rising abnormally.

A blower 2 (as an example, an axial fan) for drawing air containing suspended particulate matter into the duct 1 is provided downstream. A high voltage power source 3 supplies a high voltage to the charging unit 11 and the dust collecting unit 21.

図２は、帯電部１１と集じん部２１の斜視図であり、帯電部１１は、高圧電源３の正極側に電気的に導通させた放電電極１２と同アース側に電気的に導通させた接地電極板１３とが交互に配置されており、集じん部２１は、高圧電源３の正極側に電気的に導通させた荷電極板２２と同アース側に電気的に導通させた接地極板２３とが交互に配置されている。放電電極１２の形状は、線状、トゲ状、針状など、放電しやすい形状ならいずれでもよく、また材質は、ステンレス、タングステンなどの金属をはじめ、導電性塗料や導電性フィルムなど、導電性物質ならいずれでもよい。また、放電電極１２および荷電極板２２は、高圧電源３の正極側に接続されているが、アース極に対して負極側に接続してもよい。   FIG. 2 is a perspective view of the charging unit 11 and the dust collecting unit 21. The charging unit 11 is electrically connected to the ground side and the discharge electrode 12 electrically connected to the positive electrode side of the high-voltage power supply 3. The ground electrode plates 13 are alternately arranged, and the dust collector 21 is a ground electrode plate electrically connected to the ground side and the load electrode plate 22 electrically connected to the positive electrode side of the high-voltage power source 3. 23 are alternately arranged. The shape of the discharge electrode 12 may be any shape that is easy to discharge, such as a line shape, a thorn shape, or a needle shape, and the material is conductive such as a metal such as stainless steel or tungsten, a conductive paint, a conductive film, or the like. Any substance is acceptable. Moreover, although the discharge electrode 12 and the load electrode plate 22 are connected to the positive electrode side of the high-voltage power supply 3, they may be connected to the negative electrode side with respect to the ground electrode.

図２において、帯電部１１の放電電極１２と接地電極板１３との隙間、および集じん部２１の荷電電極２２と接地電極２３との隙間を矢印の如く空気が流れ、帯電部１１において放電電極１２と接地電極板１３との間に発生したコロナ放電によって空気中の浮遊粒子状物質が帯電され、集じん部２１において荷電極板２２と接地極板２３との間に発生した電界によって、帯電した浮遊粒子状物質がクーロン力により接地極板２３に付着、捕集される。これによって、空気中の浮遊粒子状物質を捕集し空気清浄を行うことができる。   In FIG. 2, air flows through the gap between the discharge electrode 12 and the ground electrode plate 13 of the charging unit 11 and the gap between the charge electrode 22 and the ground electrode 23 of the dust collection unit 21 as indicated by arrows. The suspended particulate matter in the air is charged by the corona discharge generated between the electrode 12 and the ground electrode plate 13, and is charged by the electric field generated between the load electrode plate 22 and the ground electrode plate 23 in the dust collection portion 21. The suspended particulate matter adheres to the ground electrode plate 23 and is collected by the Coulomb force. As a result, airborne particulate matter in the air can be collected and air purified.

図３は、図１および図２における、帯電部１１の接地電極板１３、集じん部２１の荷電極板２２、集じん部２１の接地極板２３のうち、いずれかまたは複数種に用いられる３層フィルム３１を含む極板の、実施の形態１を示す詳細図および断面図である。なお、３層フィルム３１を用いない極板は、ステンレスやアルミニウムなどの金属板であってもよい。   3 is used for any one or more of the ground electrode plate 13 of the charging unit 11, the load electrode plate 22 of the dust collection unit 21, and the ground electrode plate 23 of the dust collection unit 21 in FIGS. It is the detailed view and sectional drawing which show Embodiment 1 of the electrode plate containing the three-layer film 31. The electrode plate not using the three-layer film 31 may be a metal plate such as stainless steel or aluminum.

図３において、３層フィルム３１は、２枚の第１フィルム３２の間に、第２フィルム３３を挟んで構成されている。ここで、第１フィルム３２および第２フィルム３３の材質としては、いずれもポリフッ化ビニリデン系樹脂（以降、ＰＶＤＦと呼ぶ）を用いている。ＰＶＤＦは、耐熱性、耐オゾン性、耐薬品性、耐油性などに優れ、耐久性を十分確保することが出来るとともに、フィルム基材にイオン性導電剤を混ぜ込むことによって、体積抵抗率が違う複数種のフィルムを製作することができる。一般に体積抵抗率を調整する手段としては、カーボンなどの導電性フィラーを混ぜ込む方式があるが、この方式は樹脂材料に高電圧をかけた時にカーボン粒子の部分で絶縁破壊を起こしやすく、絶縁破壊電圧が低いといった欠点があるため、これを解決する手段として本実施の形態１では、カーボンなどの導電性フィラーに代わって、イオン性導電剤を混ぜ込む方式を用いている。その結果、体積抵抗率の異なる第１フィルム３２と第２フィルム３３が同種の樹脂材料で製作でき、これに熱をかけて接触面を溶解して密着させる熱溶着を行うことによって、３層フィルム３１の密着性が良くなり、３層フィルム３１の「はがれ」に対する信頼性を大幅に向上させることができる。   In FIG. 3, the three-layer film 31 is configured by sandwiching a second film 33 between two first films 32. Here, as the material of the first film 32 and the second film 33, both are polyvinylidene fluoride resins (hereinafter referred to as PVDF). PVDF is excellent in heat resistance, ozone resistance, chemical resistance, oil resistance, etc., and can ensure sufficient durability, and the volume resistivity is different by mixing ionic conductive agent into the film base material Multiple types of films can be produced. In general, as a means of adjusting the volume resistivity, there is a method of mixing a conductive filler such as carbon, but this method easily causes dielectric breakdown at the carbon particle portion when a high voltage is applied to the resin material, and the dielectric breakdown. Since there is a disadvantage that the voltage is low, in the first embodiment, a method of mixing an ionic conductive agent in place of the conductive filler such as carbon is used as a means for solving this. As a result, the first film 32 and the second film 33 having different volume resistivity can be manufactured with the same kind of resin material, and heat is applied to the first film 32 and the second film 33 to melt the contact surface and thereby heat-contact the three-layer film. The adhesion of 31 is improved, and the reliability of the three-layer film 31 with respect to “peeling” can be greatly improved.

この３層フィルム３１を帯電部１１の接地電極板１３に用いる場合は、第１フィルム３２の体積抵抗率が１０9〜１０12Ω・ｃｍであり、第２フィルム３３の体積抵抗率が１０4Ω・ｃｍ以下であり、いずれのフィルムも厚みを１００〜５００μｍとしている。 When the three-layer film 31 is used for the ground electrode plate 13 of the charging unit 11, the volume resistivity of the first film 32 is 10 9 to 10 12 Ω · cm, and the volume resistivity of the second film 33 is 10 4. Ω · cm or less, and any film has a thickness of 100 to 500 μm.

帯電部１１における第２フィルム３３は、帯電部１１でコロナ放電を行う際の電流を集め導通させる役目があるが、体積抵抗率が１０4Ω・ｃｍより高いと電流が流れる際に第２フィルム３３自体がジュール熱によって発熱量が大きくなってしまうため、１０4Ω・ｃｍ以下としている。厚みに関しては１００〜５００μｍが良く、１００μｍより薄いと、同様に電流が流れる際に第２フィルム３３自体がジュール熱によって発熱してしまい、５００μｍより厚いと第２フィルム３３の重量が重くなり軽量化に寄与できなくなる。 The second film 33 in the charging unit 11 has a function of collecting and conducting current when corona discharge is performed in the charging unit 11. However, when the volume resistivity is higher than 10 4 Ω · cm, the second film 33 is used when the current flows. Since 33 itself has a large amount of heat generation due to Joule heat, it is set to 10 4 Ω · cm or less. The thickness is preferably 100 to 500 μm. If the thickness is less than 100 μm, the second film 33 itself generates heat due to Joule heat when the current flows. If the thickness is more than 500 μm, the weight of the second film 33 becomes heavy and the weight is reduced. Can no longer contribute.

帯電部１１における第１フィルム３２は、帯電部１１でコロナ放電を行う際に火花放電の発生を抑える役目がある。通常、接地電極板１３表面が導電性であると、コロナ放電中に空気の絶縁破壊が起きた時に、その箇所の空気の電気抵抗が限りなくゼロに近づき、集中して電流が流れ火花放電が発生する。一方、接地電極板１３の表面を、電気抵抗を持ったの第１フィルム３２で覆った場合は、もし、コロナ放電中に空気の絶縁破壊が起き、その箇所の空気の電気抵抗が限りなくゼロに近づいた時でも、第１フィルム３２の抵抗が直列にあるため、他の箇所の抵抗（空気抵抗＋フィルム抵抗）と比べて抵抗値の差が少なく、電流を分散させ一箇所に集中して電流が流れずに火花放電の発生を防止することができる。この時の第１フィルム３２の体積抵抗率は１０9〜１０12Ω・ｃｍ、また、厚みは１００〜５００μｍとすることが適正である。 The first film 32 in the charging unit 11 serves to suppress the occurrence of spark discharge when corona discharge is performed in the charging unit 11. Normally, if the surface of the ground electrode plate 13 is conductive, when air breakdown occurs during corona discharge, the electrical resistance of the air at that location approaches zero as much as possible, current flows intensively and spark discharge occurs. appear. On the other hand, if the surface of the ground electrode plate 13 is covered with the first film 32 having electric resistance, if the dielectric breakdown of the air occurs during corona discharge, the electric resistance of the air at that location is infinitely zero. Even when approaching, the resistance of the first film 32 is in series, so there is little difference in resistance compared to the resistance of other places (air resistance + film resistance), and the current is dispersed and concentrated in one place The occurrence of spark discharge can be prevented without current flowing. It is appropriate that the volume resistivity of the first film 32 at this time is 10 9 to 10 12 Ω · cm, and the thickness is 100 to 500 μm.

以下、その理由について述べる。体積抵抗率が同じでも厚みが変わるとフィルムの厚み方向に流れる電流に対する抵抗は変わってくる。そのため、フィルムの厚み方向に流れる電流に対する単位面積あたりの抵抗（つまり、体積抵抗率と厚みの積、以降、面積抵抗率Ω・ｃｍ2と呼ぶ）を考えると、本発明者らはこの面積抵抗率が１０8〜１０10Ω・ｃｍ2とすることが最適であることを見出した。例えば厚さ１００μｍのフィルムでは、体積抵抗率１×１０10〜１×１０12Ω・ｃｍが、また厚さ５００μｍのフィルムでは、体積抵抗率２×１０9〜２×１０11Ω・ｃｍが最適となる。この面積抵抗率が１０8Ω・ｃｍ2より小さいと電流が流れやすくなりコロナ放電は発生するが火花放電も発生し、逆に１０10Ω・ｃｍ2より大きいと火花放電は発生しないが、コロナ放電も発生しなくなる。最適設計の一例として、第１フィルム３２の面積抵抗率を１×１０9Ω・ｃｍ2（この時、体積抵抗率は２．５×１０10Ω・ｃｍ、厚みは４００μｍ）とするとよい。 The reason will be described below. Even if the volume resistivity is the same, if the thickness changes, the resistance to the current flowing in the thickness direction of the film changes. Therefore, considering the resistance per unit area with respect to the current flowing in the thickness direction of the film (that is, the product of volume resistivity and thickness, hereinafter referred to as area resistivity Ω · cm 2 ), the present inventors have determined this area resistance. It has been found that it is optimal that the rate is 10 8 to 10 10 Ω · cm 2 . For example, a volume resistivity of 1 × 10 10 to 1 × 10 12 Ω · cm is optimal for a film having a thickness of 100 μm, and a volume resistivity of 2 × 10 9 to 2 × 10 11 Ω · cm is optimal for a film having a thickness of 500 μm. It becomes. If this area resistivity is less than 10 8 Ω · cm 2 , current flows easily and corona discharge occurs, but spark discharge also occurs. Conversely, if it is greater than 10 10 Ω · cm 2 , spark discharge does not occur. There is no discharge. As an example of the optimum design, the area resistivity of the first film 32 may be 1 × 10 9 Ω · cm 2 (the volume resistivity is 2.5 × 10 10 Ω · cm and the thickness is 400 μm).

一方、この３層フィルム３１を集じん部２１の荷電極板２２または接地極板２３に用いる場合は、第１フィルム３２の体積抵抗率が１０9Ω・ｃｍ以上であり、第２フィルム３３の体積抵抗率が１０4Ω・ｃｍ以下であり、いずれのフィルムも厚みを１００〜５００μｍとしている。 On the other hand, when the three-layer film 31 is used for the load electrode plate 22 or the ground electrode plate 23 of the dust collecting portion 21, the volume resistivity of the first film 32 is 10 9 Ω · cm or more. The volume resistivity is 10 4 Ω · cm or less, and any film has a thickness of 100 to 500 μm.

集じん部２１における第２フィルム３３は、集じん部２１で電界をかけた際に電位を保つ役目があるが、体積抵抗率が１０4Ω・ｃｍより高いと電圧降下によって極板の電位を保つことができなくなってしまうため、１０4Ω・ｃｍ以下としている。厚みに関しては１００〜５００μｍが良く、１００μｍより薄いと電圧降下によって極板の電位を保つことができなくなり、５００μｍより厚いと第２フィルム３３の重量が重くなり軽量化に寄与できない。 The second film 33 in the dust collection portion 21 has a role of maintaining a potential when an electric field is applied in the dust collection portion 21. However, if the volume resistivity is higher than 10 4 Ω · cm, the potential of the electrode plate is reduced by a voltage drop. Since it cannot be maintained, it is set to 10 4 Ω · cm or less. The thickness is preferably 100 to 500 μm. If the thickness is less than 100 μm, the potential of the electrode plate cannot be maintained due to a voltage drop. If the thickness is greater than 500 μm, the weight of the second film 33 is increased and cannot contribute to weight reduction.

集じん部２１における第１フィルム３２も、帯電部１１同様に火花放電の発生を抑える役目がある。ただし、帯電部１１と違いコロナ放電を行う必要がなく、第２フィルム３３において電界を保てばよいため、第１フィルム３２は絶縁性を高くすることが望ましい。よって、帯電部１１と同様の理由で、体積抵抗率は１０9Ω・ｃｍ以上とし、また、厚みは１００〜５００μｍ（上限は絶縁性には関係ないが、厚すぎると軽量化に寄与できないため）とすることが適正である。 The first film 32 in the dust collection portion 21 also has a role of suppressing the occurrence of spark discharge, like the charging portion 11. However, unlike the charging unit 11, it is not necessary to perform corona discharge, and it is only necessary to maintain an electric field in the second film 33. Therefore, it is desirable that the first film 32 has high insulation. Therefore, for the same reason as the charging unit 11, the volume resistivity is set to 10 9 Ω · cm or more, and the thickness is 100 to 500 μm (the upper limit is not related to insulation, but if it is too thick, it cannot contribute to weight reduction). ) Is appropriate.

以上のことから、帯電部１１または集じん部２１において火花放電の発生を抑えることにより温度の異常上昇を未然に防止するとともに、印加電圧を下げたり極板間隔を広げたりすることなく集じん機能を維持しつつ、極板を３層フィルム３１にすることにより、金属製極板に比べて大幅な軽量化を図ることができるものである。   From the above, by preventing the occurrence of spark discharge in the charging unit 11 or the dust collection unit 21, it is possible to prevent an abnormal increase in temperature and to collect dust without lowering the applied voltage or increasing the electrode plate interval. By maintaining the electrode plate as the three-layer film 31, the weight can be significantly reduced as compared with the metal electrode plate.

３層フィルム３１は単独では剛性がないため、図３に示すように、周囲を剛体としてのフレーム３４（フレームＡ３４ａ、フレームＢ３４ｂ）に挟み、４箇所の穴３５にボルトとナット（図示せず）を通すことにより締結し、剛性を保っている。この方式は、極板を簡単に組立てることが可能となる。なお、フレーム３４は、剛性があれば金属であっても樹脂であってもよい。   Since the three-layer film 31 does not have rigidity alone, as shown in FIG. 3, the periphery is sandwiched between frames 34 (frame A 34a, frame B 34b) as rigid bodies, and bolts and nuts (not shown) are inserted into four holes 35. It is fastened by passing it through to maintain rigidity. This method makes it possible to easily assemble the electrode plate. The frame 34 may be a metal or a resin as long as it has rigidity.

一方、いずれの極板の使い方であっても、第２フィルム３３は、高圧電源３に電気的に導通させる必要があり、本実施の形態１では、３層フィルム３１が、少なくとも１辺の端面に平行に所定の幅（例えば１０ｍｍ）で１枚の第１フィルム３２と１枚の第２フィルム３３の２層のみで構成された表面露出部３６を設けている。そして、第２フィルム３３の表面露出部３６に導電性の通電板３７を接触させ、さらに、フレームＡ３４ａ、フレームＢ３４ｂによって両側から挟み込んでいる。通電板３７の少なくとも一端は、通電端子３８としてフレーム３４の外側に突出させ、この通電端子３８をリード線（図示せず）などを介して高圧電源３に接続することにより、第２フィルム３３を確実に高圧電源３に導通させることができるものである。これにより、信頼性を高めることができる。   On the other hand, regardless of how the electrode plate is used, the second film 33 needs to be electrically connected to the high-voltage power source 3, and in the first embodiment, the three-layer film 31 has at least one end face. The exposed surface portion 36 is formed in parallel with the first exposed film 36 and has a predetermined width (for example, 10 mm) and is formed of only two layers of one first film 32 and one second film 33. The conductive energizing plate 37 is brought into contact with the surface exposed portion 36 of the second film 33, and is further sandwiched from both sides by the frame A34a and the frame B34b. At least one end of the energizing plate 37 protrudes to the outside of the frame 34 as an energizing terminal 38, and the energizing terminal 38 is connected to the high-voltage power source 3 via a lead wire (not shown) or the like, whereby the second film 33 is It is possible to ensure conduction to the high-voltage power supply 3. Thereby, reliability can be improved.

また、本実施の形態１では、３層フィルム３１の全幅寸法がＢ＝２００ｍｍ、表面露出部の幅寸法が１０ｍｍとすると、全幅２００ｍｍのうち、幅１９０ｍｍが３層構成、幅１０ｍｍが２層構成のフィルムを長尺で製作し、長手方向に所定長さ（例えば４００ｍｍ）に裁断することによって、３層フィルム３１を安価で簡単に形成することができるものである。   In the first embodiment, when the total width dimension of the three-layer film 31 is B = 200 mm and the width dimension of the surface exposed portion is 10 mm, among the total width 200 mm, the width 190 mm has a three-layer configuration, and the width 10 mm has a two-layer configuration. The three-layer film 31 can be easily formed at a low cost by producing a long film and cutting the film into a predetermined length (for example, 400 mm) in the longitudinal direction.

図４は、図１および図２における、帯電部１１の接地電極板１３、集じん部２１の荷電極板２２、集じん部２１の接地極板２３のうち、いずれかまたは複数種に用いられる３層フィルム３１を含む極板の、実施の形態２を示す詳細図および断面図である。図３と同じ構成要素については同じ符号を用い、説明を省略する。なお、３層フィルム３１を用いない極板は、ステンレスやアルミニウムなどの金属板であってもよい。 (Embodiment 2)
4 is used for any one or more of the ground electrode plate 13 of the charging unit 11, the load electrode plate 22 of the dust collection unit 21, and the ground electrode plate 23 of the dust collection unit 21 in FIGS. It is the detailed view and sectional drawing which show Embodiment 2 of the electrode plate containing the three-layer film 31. The same components as those in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted. The electrode plate not using the three-layer film 31 may be a metal plate such as stainless steel or aluminum.

図４において、３層フィルム３１は、２枚の第１フィルム３２の間に、第２フィルム３３を挟んで構成されている。ここで、第１フィルム３２および第２フィルム３３の材質としては、いずれも厚さ１００〜５００μｍのポリフッ化ビニリデン系樹脂を用いている。３層フィルム３１の周囲は、金属や樹脂などの剛体としてのフレーム３４（フレームＡ３４ａ、フレームＢ３４ｂ）によって挟まれ、４箇所の穴３５にボルトとナット（図示せず）を通すことにより締結し、剛性を保っている。   In FIG. 4, the three-layer film 31 is configured by sandwiching a second film 33 between two first films 32. Here, as a material of the first film 32 and the second film 33, a polyvinylidene fluoride resin having a thickness of 100 to 500 μm is used. The periphery of the three-layer film 31 is sandwiched between rigid frames 34 (frame A34a, frame B34b) such as metal or resin, and fastened by passing bolts and nuts (not shown) through four holes 35, Maintains rigidity.

第２フィルム３３は、高圧電源３に電気的に導通させる必要があり、本実施の形態２では、３層フィルム３１の少なくとも１辺の端面において、３層フィルム３１の表面方向に対しα＝５〜３０°（本実施の形態２では、α＝２５°）の角度で斜めに切除することによって、表面露出部３６を形成している。そして、第２フィルム３３の表面露出部３６に導電性の通電板３７を接触させ、さらに、フレームＡ３４ａ、フレームＢ３４ｂによって両側から挟み込んでいる。角度をα＝５〜３０°とした理由は、角度が３０°より大きいと、通電板３７と第２フィルム３３との接触長さが小さくなり電気の導通を阻害するおそれがあり、角度が５°より小さいと、３層フィルム３１が３層として機能する有効面積が小さくなるためである。なお、フレームＡ３４ａの通電板３７に対応する部分は、３層フィルム３１の切除角を考慮して、３層フィルム３１の表面方向に対し、部分的に斜めに形成されている。さらに、通電板３７の少なくとも一端は、通電端子３８としてフレーム３４の外側に突出させ、この通電端子３８をリード線（図示せず）などを介して高圧電源３に接続することにより、第２フィルム３３を確実に高圧電源３に導通させることができるものである。これにより、信頼性を高めることができる。   The second film 33 needs to be electrically connected to the high-voltage power supply 3. In the second embodiment, α = 5 with respect to the surface direction of the three-layer film 31 at the end surface of at least one side of the three-layer film 31. The surface exposed portion 36 is formed by cutting obliquely at an angle of ˜30 ° (α = 25 ° in the second embodiment). The conductive energizing plate 37 is brought into contact with the surface exposed portion 36 of the second film 33, and is further sandwiched from both sides by the frame A34a and the frame B34b. The reason why the angle is set to α = 5 to 30 ° is that when the angle is larger than 30 °, the contact length between the energizing plate 37 and the second film 33 may be reduced, which may hinder electrical conduction. This is because the effective area where the three-layer film 31 functions as a three-layer becomes smaller if it is smaller than 0 °. In addition, the part corresponding to the electricity supply plate 37 of the frame A 34 a is formed obliquely with respect to the surface direction of the three-layer film 31 in consideration of the cutting angle of the three-layer film 31. Further, at least one end of the energizing plate 37 protrudes to the outside of the frame 34 as an energizing terminal 38, and the energizing terminal 38 is connected to the high-voltage power source 3 via a lead wire (not shown) or the like, whereby the second film 33 can be reliably connected to the high-voltage power source 3. Thereby, reliability can be improved.

この方式は、３層フィルム３１の表面露出部３６を、フィルムの３層構造成形後の、あと加工で形成することができるため、３層フィルム３１を広い面積で大量に成形することができ、３層フィルムの製造コストを低減することができるものである。   In this method, the surface exposed portion 36 of the three-layer film 31 can be formed by post-processing after forming the three-layer structure of the film, so the three-layer film 31 can be molded in a large area in a large area, The manufacturing cost of the three-layer film can be reduced.

図５は、図１および図２における、帯電部１１の接地電極板１３、集じん部２１の荷電極板２２、集じん部２１の接地極板２３のうち、いずれかまたは複数種に用いられる３層フィルム３１を含む極板の、実施の形態３を示す詳細図および断面図である。図３と同じ構成要素については同じ符号を用い、説明を省略する。なお、３層フィルム３１を用いない極板は、ステンレスやアルミニウムなどの金属板であってもよい。 (Embodiment 3)
FIG. 5 is used for any one or more of the ground electrode plate 13 of the charging unit 11, the load electrode plate 22 of the dust collection unit 21, and the ground electrode plate 23 of the dust collection unit 21 in FIGS. 1 and 2. It is the detailed view and sectional drawing which show Embodiment 3 of the electrode plate containing the three-layer film 31. The same components as those in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted. The electrode plate not using the three-layer film 31 may be a metal plate such as stainless steel or aluminum.

図５において、３層フィルム３１は、２枚の第１フィルム３２の間に、第２フィルム３３を挟んで構成されている。ここで、第１フィルム３２および第２フィルム３３の材質としては、いずれも厚さ１００〜５００μｍのポリフッ化ビニリデン系樹脂を用いている。３層フィルム３１の周囲は、金属や樹脂などの剛体としてのフレーム３４（フレームＡ３４ａ、フレームＢ３４ｂ）によって挟まれ、４箇所の穴３５にボルトとナット（図示せず）を通すことにより締結し、剛性を保っている。   In FIG. 5, the three-layer film 31 is configured by sandwiching a second film 33 between two first films 32. Here, as a material of the first film 32 and the second film 33, a polyvinylidene fluoride resin having a thickness of 100 to 500 μm is used. The periphery of the three-layer film 31 is sandwiched between rigid frames 34 (frame A34a, frame B34b) such as metal or resin, and fastened by passing bolts and nuts (not shown) through four holes 35, Maintains rigidity.

フレームＡ３４ａには、内面に３層フィルム３１の表面方向に垂直方向にメネジ４１ａを設けたボス４１が４箇所備えられている。このボス４１に、先端４２ａが尖った円錐形で中央部にオネジ４２ｂを設けた導電性の通電棒４２をねじ込むことにより、３層フィルム３１に対しくさび状に差し込むようにしてある。ここで、通電棒４２の先端４２ａを円錐形にした理由は、通電棒４２が第２フィルム３３に接触する部分において、常に第２フィルム３３の穴を拡大する力が働き、第２フィルム３３の僅かな厚み（１００〜５００μｍ）であっても、通電棒４２と第２フィルム３３とを確実に接触させるためである。この通電棒４２をリード線（図示せず）などを介して高圧電源３に接続することにより、第２フィルム３３を確実に高圧電源３に導通させることができるものである。これにより、信頼性を高めることができる。   The frame A 34 a is provided with four bosses 41 provided with female screws 41 a in the direction perpendicular to the surface direction of the three-layer film 31 on the inner surface. The boss 41 is inserted into the three-layer film 31 in a wedge shape by screwing a conductive current bar 42 having a conical shape with a sharp tip 42a and a male screw 42b at the center. Here, the reason why the tip 42a of the current-carrying rod 42 is conical is that the force that always enlarges the hole of the second film 33 works in the portion where the current-carrying rod 42 contacts the second film 33. This is because the current-carrying rod 42 and the second film 33 are reliably brought into contact with each other even if the thickness is small (100 to 500 μm). By connecting the current-carrying rod 42 to the high-voltage power supply 3 via a lead wire (not shown) or the like, the second film 33 can be reliably connected to the high-voltage power supply 3. Thereby, reliability can be improved.

この方式は、既に成形された３層フィルム３１に加工を施すことなく、第２フィルム３３を確実に高圧電源３に導通させることができるもので、３層フィルム３１を用いた極板の製作を安価で簡単に行なうことができるものである。   In this method, the second film 33 can be reliably conducted to the high-voltage power source 3 without processing the already formed three-layer film 31, and an electrode plate using the three-layer film 31 can be manufactured. It is cheap and can be performed easily.

The conductive boss 42 having a conical shape with a sharp tip 42a and a male screw 42b at the center is screwed into the boss 41 so that the boss 41 is inserted into the second film 33 of the three-layer film 31 in a wedge shape. is there. Here, the reason why the tip 42a of the current-carrying rod 42 is conical is that a force that always enlarges the hole of the second film 33 acts on the part where the current-carrying rod 42 contacts the second film 33, This is because the two films 33 are brought into contact with each other with certainty. By connecting the current-carrying rod 42 to the high-voltage power supply 3 via a lead wire (not shown) or the like, the second film 33 can be reliably connected to the high-voltage power supply 3. Thereby, reliability can be improved.

この方式は、既に成形された３層フィルム３１に加工を施すことなく、第２フィルム３３をより確実に高圧電源３に導通させることができるもので、３層フィルム３１を用いた極板の製作を安価で簡単に行なうことができるものである。   In this method, the second film 33 can be more reliably conducted to the high-voltage power source 3 without processing the already formed three-layer film 31. Production of an electrode plate using the three-layer film 31 is possible. Is cheap and can be performed easily.
