Description

本発明は、空気中の大気塵を除去する空気清浄用フィルタに関するものである。   The present invention relates to an air cleaning filter that removes atmospheric dust in the air.

（従来技術１）
大気塵を除去して空気を清浄にする空気清浄装置として、図１３に示すような２段式電気集塵機が従来から一般的に知られている。以下、その２段式電気集塵機について説明する。 (Prior art 1)
A two-stage electrostatic precipitator as shown in FIG. 13 has been generally known as an air cleaning device that removes atmospheric dust and cleans the air. Hereinafter, the two-stage electrostatic precipitator will be described.

従来の２段式電気集塵機は図１３に示すように上流側から順に帯電部１０１、集塵部１０４で構成されている。   As shown in FIG. 13, the conventional two-stage electrostatic precipitator includes a charging unit 101 and a dust collecting unit 104 in order from the upstream side.

帯電部１０１は線状の放電電極１０２とそれを挟むように設けられた帯電部アース電極板１０３とで構成される。放電電極１０２には高圧電源１０７によって高電圧が印加され、帯電部アース電極板１０３にはアースが接続されて０Ｖとなっており、両者の間でコロナ放電が発生する。   The charging unit 101 includes a linear discharge electrode 102 and a charging unit ground electrode plate 103 provided so as to sandwich it. A high voltage is applied to the discharge electrode 102 by the high-voltage power source 107, and the charging portion ground electrode plate 103 is connected to the ground and becomes 0 V. Corona discharge occurs between the two.

集塵部１０４は高圧電極板１０５および集塵部アース電極板１０６とで構成される。高圧電極板１０５と集塵部アース電極板１０６は一定の間隔を開けて空間を設けながら交互に積層されている。高圧電極板１０５には高圧電源１０７によって高電圧が印加され、集塵部アース電極板にはアースが接続されて０Ｖとなっており、両者の間に作られた空間には電場が設けられている。   The dust collection unit 104 includes a high voltage electrode plate 105 and a dust collection unit ground electrode plate 106. The high-voltage electrode plate 105 and the dust collecting portion ground electrode plate 106 are alternately stacked while providing a space at a predetermined interval. A high voltage is applied to the high-voltage electrode plate 105 by a high-voltage power source 107, the ground is connected to the dust collecting portion ground electrode plate, and is 0 V, and an electric field is provided in the space created between the two. Yes.

通風方向１０８に沿って空気は２段式電気集塵機に取り込まれ、その空気中に含まれる大気塵は帯電部１０１においてコロナ放電で発生した空気イオンと衝突して帯電する。帯電した大気塵は下流側にある集塵部１０４に送り込まれ、高圧電極板１０５と集塵部アース電極板１０６の間に作られた空間を通過する。そして空間に設けられた電場によってクーロン力を受け、移動する。図１３のように放電電極１０２および高圧電極板１０５にそれぞれ正極の高電圧が印加されている場合、大気塵は正に帯電し、正に帯電した大気塵は高圧電極板１０５から集塵部アース電極板１０６へと移動して集塵部アース電極板１０６に付着し、空気中から除去される。   Air is taken into the two-stage electrostatic precipitator along the ventilation direction 108, and atmospheric dust contained in the air collides with air ions generated by corona discharge in the charging unit 101 and is charged. The charged atmospheric dust is sent to the dust collecting unit 104 on the downstream side, and passes through a space formed between the high voltage electrode plate 105 and the dust collecting unit ground electrode plate 106. And it moves by receiving Coulomb force by the electric field provided in the space. As shown in FIG. 13, when a positive high voltage is applied to the discharge electrode 102 and the high-voltage electrode plate 105, the atmospheric dust is positively charged, and the positively charged atmospheric dust is grounded from the high-voltage electrode plate 105 to the dust collector ground. It moves to the electrode plate 106, adheres to the dust collecting portion ground electrode plate 106, and is removed from the air.

また、別の集塵装置として、特許文献１（第１図）に記載の空気清浄装置がある。以下、図１４を用いてこの空気清浄装置を説明する。図１４に記載の空気清浄装置は上流側から順に帯電部１０１、誘電濾材１０９で構成される。帯電部１０１は先の（従来技術１）に記載のものと同じで、通過した大気塵をコロナ放電によって帯電させる。誘電濾材１０９は誘電繊維１０９ａと導電繊維１０９ｂとを混紡してシート化されたものであり、また、アースに接続されている。そして高電圧が印加された放電電極１０２と導電繊維１０９ｂとの間に電場が設けられ、その電場の中に存在する誘電繊維１０９ａは誘電分極して電荷が誘起される。 (Prior art 2)
Moreover, there exists an air purifying apparatus as described in patent document 1 (FIG. 1) as another dust collector. Hereinafter, this air cleaning apparatus will be described with reference to FIG. The air purifying apparatus shown in FIG. 14 includes a charging unit 101 and a dielectric filter medium 109 in order from the upstream side. The charging unit 101 is the same as that described in (Prior Art 1), and charges the atmospheric dust that has passed through corona discharge. The dielectric filter medium 109 is a sheet formed by mixing dielectric fibers 109a and conductive fibers 109b, and is connected to the ground. An electric field is provided between the discharge electrode 102 to which a high voltage is applied and the conductive fiber 109b, and the dielectric fiber 109a existing in the electric field is dielectrically polarized to induce charges.

通風方向１０８に沿って帯電部１０１を通過した空気中の大気塵は帯電し、帯電した大気塵は電場によって電荷が誘起された誘電繊維１０９ａによって吸着捕集される。   The atmospheric dust in the air that has passed through the charging unit 101 along the ventilation direction 108 is charged, and the charged atmospheric dust is adsorbed and collected by the dielectric fiber 109a in which the charge is induced by the electric field.

（従来技術３）
また、別の集塵装置として、特許文献２（第１図）に記載のフィルタがある。以下、図１５を用いてこのフィルタを説明する。支持板１１１に無数の帯電繊維１１０が固定された帯電繊維集合体１１２が形成される。隣接する帯電繊維１１０どうしの間には帯電繊維が有する電荷によって電場が設けられている。そして通気性を有する段ボール状の中空スペーサー１１３と帯電繊維集合体１１２とを交互に４つずつ積層したものを仕切り板１１４で仕切りながらフィルタケース１１５に納めた構造となっている。 (Prior art 3)
Moreover, there exists a filter as described in patent document 2 (FIG. 1) as another dust collector. Hereinafter, this filter will be described with reference to FIG. A charged fiber assembly 112 in which countless charged fibers 110 are fixed to the support plate 111 is formed. An electric field is provided between the adjacent charged fibers 110 by the charge of the charged fibers. Then, a structure in which corrugated hollow spacers 113 having air permeability and four charged fiber aggregates 112 are alternately stacked and stored in a filter case 115 while being partitioned by a partition plate 114 is provided.

そして通風方向１０８に沿って空気はフィルタに取り込まれ、空気中の大気塵は帯電繊維１１０どうしの作る電場によって吸着捕集される。   Air is taken into the filter along the ventilation direction 108, and atmospheric dust in the air is adsorbed and collected by an electric field created by the charged fibers 110.

従来技術１に記載の２段式電気集塵機は、集塵部を作るために多数の高圧電極板と集塵部アース電極板を一定の間隔を開けながら交互に積層しなくてはいけないため、構造が複雑で作るのが大変難しい。また、高圧電極板には高電圧が印加されるため、安全のために人が触れないようにしたり、また、集塵部アース電極板や集塵部を納める金属製フレームとの間で短絡が起きないようにしなくてはならず、簡単に作ることができない。   The two-stage electrostatic precipitator described in Prior Art 1 has a structure in which a large number of high-voltage electrode plates and dust collector ground electrode plates must be alternately stacked with a certain interval in order to form a dust collector. Is complicated and very difficult to make. In addition, high voltage is applied to the high-voltage electrode plate, so that it cannot be touched by humans for safety, and there is a short circuit between the dust collector ground electrode plate and the metal frame that houses the dust collector. You have to make sure you don't get up and you can't make it easily.

また、従来技術２に記載の空気清浄装置は誘電濾材に高電圧を印加する必要がなく比較的簡単に作れるが、シート状のため通風方向が濾材に対して垂直になり、捕集した大気塵は濾材の上に堆積して通風に必要な隙間を埋めてしまう。そのため目詰まりが早く起こってしまい、通風量が短期間で減ってしまう。   In addition, the air cleaning device described in the prior art 2 can be made relatively easily without applying a high voltage to the dielectric filter medium. However, because of the sheet shape, the ventilation direction is perpendicular to the filter medium, and the collected atmospheric dust Accumulates on the filter media and fills the gaps necessary for ventilation. Therefore, clogging occurs early, and the air flow rate decreases in a short period.

また、通風方向に対して垂直な平面状の電場が１面のみ作られた構造であるため、通風方向に奥行きのある電場がなく、高い集塵性能が得られない。   In addition, since it has a structure in which only one planar electric field perpendicular to the ventilation direction is created, there is no electric field having a depth in the ventilation direction, and high dust collection performance cannot be obtained.

また、混紡するには短い誘電繊維と短い導電繊維を溶液中に混ぜて紙を漉くように作るのが現実的だが、短い導電繊維を用いて混紡すると導電繊維どうしを接触させて導通させることが難しく、誘電濾材をアースに接続して０Ｖにすることが容易にできない。   In order to blend, it is realistic to mix a short dielectric fiber and a short conductive fiber in a solution so as to spread the paper. However, if a short conductive fiber is used for blending, the conductive fibers can be brought into contact with each other to conduct electricity. Difficult, it is not easy to connect the dielectric filter media to ground and make it 0V.

また、従来技術３記載のフィルタは帯電繊維どうしの電位差が明確でなく、帯電繊維どうしが作る電場が強くない。そのため高い集塵性能が得られない。また、大気塵を捕集していくうちに帯電繊維の帯電が落ちてしまい、集塵性能が徐々に下がってしまう。   Further, in the filter described in Prior Art 3, the potential difference between the charged fibers is not clear, and the electric field created by the charged fibers is not strong. Therefore, high dust collection performance cannot be obtained. In addition, as the atmospheric dust is collected, the charged fibers are uncharged, and the dust collection performance is gradually lowered.

そこで本発明は、上記従来の課題を解決するものであり、簡単に作成でき、長期間において目詰まりせず、高い集塵性能を保つことが可能な電気集塵フィルタユニットの提供を目的とする。   SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide an electric dust collection filter unit that can be easily produced, is not clogged for a long period of time, and can maintain high dust collection performance. .

上記課題を解決するために、本発明の電気集塵フィルタユニットは、上流側に空気をイオン化するイオン化手段と、下流側にフィルタ部とを備え、フィルタ部は混在した無数の帯電繊維と導電繊維からなり、両繊維は通風方向に対して水平になるよう配置され、かつ導電繊維をアースに接続することにより初期の目的を達成するものである。   In order to solve the above-described problems, the electrostatic dust collection filter unit of the present invention includes an infinite number of charged fibers and conductive fibers including ionization means for ionizing air on the upstream side and a filter unit on the downstream side, and the filter unit is mixed. Both fibers are arranged so as to be horizontal with respect to the ventilation direction, and the initial purpose is achieved by connecting the conductive fibers to the ground.

本発明の電気集塵フィルタユニットは、イオン化手段によって発生する空気イオンを付着させることで空気中の大気塵および帯電繊維を帯電させる。したがってアースに接続された導電繊維と帯電した帯電繊維との間に電場が常に作られる。そして帯電繊維と導電繊維を通風方向に対して水平となるよう配置するため、通風方向に奥行きのある、長くて強い電場が作られる。この長くて強い電場によって、帯電した大気塵にクーロン力を与えて繊維に付着させ、大気塵を捕集する。そのため高い集塵性能を得ることができ、かつ高い集塵性能を常に維持することができる。   The electric dust collection filter unit of the present invention charges atmospheric dust and charged fibers in the air by attaching air ions generated by the ionization means. Therefore, an electric field is always created between the conductive fiber connected to the ground and the charged charged fiber. And since it arrange | positions so that a charging fiber and a conductive fiber may become horizontal with respect to a ventilation direction, a long and strong electric field with a depth in a ventilation direction is made. This long and strong electric field applies a coulomb force to the charged atmospheric dust and attaches it to the fibers to collect the atmospheric dust. Therefore, high dust collection performance can be obtained, and high dust collection performance can always be maintained.

また、イオンの付着によって帯電繊維を帯電させる原理のため、帯電繊維に直接高電圧を印加する必要がなく、安全かつ簡単な構造とすることができる。   Further, because of the principle of charging the charged fiber by the adhesion of ions, it is not necessary to apply a high voltage directly to the charged fiber, and a safe and simple structure can be achieved.

また、帯電繊維と導電繊維を通風方向に対して水平となるよう配置するため、大気塵は繊維に付着したり、繊維と繊維の間に挟まれて捕集される。そのためフィルタ部は通風方向に無数の捕集面を有するような構造となり、無数の捕集面に大気塵が分散して捕集されるため長期間目詰まりしない。   Further, since the charged fiber and the conductive fiber are arranged so as to be horizontal with respect to the ventilation direction, the atmospheric dust adheres to the fiber or is trapped between the fibers. Therefore, the filter section has a structure having innumerable collecting surfaces in the ventilation direction, and atmospheric dust is dispersed and collected on the innumerable collecting surfaces, so that it is not clogged for a long time.

本発明の請求項１記載の電気集塵フィルタユニットは、上流側に空気をイオン化するイオン化手段と、下流側にフィルタ部とを備え、フィルタ部は混在した無数の帯電繊維と導電繊維からなり、両繊維は通風方向に対して水平になるよう配置され、かつ導電繊維をアースに接続するものである。   The electrostatic precipitating filter unit according to claim 1 of the present invention comprises an ionization means for ionizing air on the upstream side and a filter part on the downstream side, and the filter part is composed of innumerable charged fibers and conductive fibers mixed together, Both fibers are disposed so as to be horizontal with respect to the ventilation direction, and the conductive fibers are connected to the ground.

これにより、イオン化手段によって発生するイオンを付着させることで空気中の大気塵および帯電繊維を帯電させる。したがってアースに接続された導電繊維と帯電した帯電繊維との間に電場が常に作られる。そして帯電繊維と導電繊維を通風方向に対して水平となるよう配置するため、通風方向に奥行きのある、長いて強い電場が作られる。この長くて強い電場によって、帯電した大気塵にクーロン力を与えて繊維に付着させ、大気塵を捕集する。そのため高い集塵性能を得ることができ、かつ高い集塵性能を常に維持することができる。   Thereby, atmospheric dust and charged fibers in the air are charged by attaching ions generated by the ionization means. Therefore, an electric field is always created between the conductive fiber connected to the ground and the charged charged fiber. And since it arrange | positions so that a charging fiber and a conductive fiber may become horizontal with respect to the ventilation direction, a long and strong electric field with a depth in the ventilation direction is made. This long and strong electric field applies a coulomb force to the charged atmospheric dust and attaches it to the fibers to collect the atmospheric dust. Therefore, high dust collection performance can be obtained, and high dust collection performance can always be maintained.

また、イオンの付着によって帯電繊維を帯電させる原理のため、帯電繊維に直接高電圧を印加する必要がなく、安全かつ簡単な構造とすることができる。   Further, because of the principle of charging the charged fiber by the adhesion of ions, it is not necessary to apply a high voltage directly to the charged fiber, and a safe and simple structure can be achieved.

また、帯電繊維と導電繊維を通風方向に対して水平となるよう配置するため、大気塵は繊維に付着したり、繊維と繊維の間に挟まれて捕集される。そのためフィルタ部は通風方向に無数の捕集面を有するような構造となり、無数の捕集面に大気塵が分散して捕集されるため長期間目詰まりしない。   Further, since the charged fiber and the conductive fiber are arranged so as to be horizontal with respect to the ventilation direction, the atmospheric dust adheres to the fiber or is trapped between the fibers. Therefore, the filter section has a structure having innumerable collecting surfaces in the ventilation direction, and atmospheric dust is dispersed and collected on the innumerable collecting surfaces, so that it is not clogged for a long time.

また、請求項２記載の電気集塵フィルタユニットは、請求項１記載の電気集塵フィルタユニットに対して、フィルタ部は支持部に固定されて一様に混在した無数の帯電繊維と導電繊維からなり、両繊維は通風方向に対して水平になるよう配置され、導電繊維と支持部は導通するように固定され、支持部を通じて導電繊維をアースに接続するものである。   Further, the electrostatic dust collecting filter unit according to claim 2 is in contrast to the electrostatic dust collecting filter unit according to claim 1, wherein the filter part is fixed to the support part and is made of countless charged fibers and conductive fibers uniformly mixed. The two fibers are arranged so as to be horizontal with respect to the ventilation direction, the conductive fibers and the support portion are fixed to be conductive, and the conductive fibers are connected to the ground through the support portion.

これにより、帯電繊維と導電繊維とを一様に混在させ、かつ支持部を通じて導電繊維を確実にアースに接続することが可能となり、帯電繊維と導電繊維との間に確実に電場を形成することができる。   This makes it possible to uniformly mix charged fibers and conductive fibers, and to reliably connect the conductive fibers to the ground through the support portion, and to reliably form an electric field between the charged fibers and the conductive fibers. Can do.

また、請求項３記載の電気集塵フィルタユニットは、請求項２記載の電気集塵フィルタユニットに対して、コの字状の支持枠の上に支持枠と直交するように帯電繊維および導電繊維を置き、その上から押さえ棒をはめ込んでかしめ、帯電繊維と導電繊維を二つ折りにした状態で固定するものである。   Further, the electrostatic dust collecting filter unit according to claim 3 is the same as the electrostatic dust collecting filter unit according to claim 2, the charged fiber and the conductive fiber on the U-shaped support frame so as to be orthogonal to the support frame. , And a presser bar is inserted and caulked from above, and the charged fiber and the conductive fiber are fixed in a folded state.

これにより、導電繊維と支持部とを確実に接触導通させた電気集塵フィルタユニットを簡単に作ることができる。   As a result, it is possible to easily make an electrostatic dust collection filter unit in which the conductive fiber and the support portion are reliably brought into contact with each other.

また、請求項４記載の電気集塵フィルタユニットは、請求項１記載の電気集塵フィルタユニットに対して、フィルタ部フレームの上流側もしくは下流側の少なくともどちらか一方に、アースに接続された、通気性を有する綿状の導電体を設け、綿状の導電体に対して垂直に接触するように、一様に混在した無数の帯電繊維と導電繊維とをフィルタ部フレームの中に入れたものをフィルタ部とするものである。   Further, the electrostatic dust collection filter unit according to claim 4 is connected to ground on at least one of the upstream side and the downstream side of the filter unit frame with respect to the electrical dust collection filter unit according to claim 1. An infinite number of uniformly charged fibers and conductive fibers are placed in the filter frame so as to provide a cotton-like conductor with air permeability and to make contact with the cotton-like conductor vertically. Is the filter section.

これにより、導電繊維と綿状の導電体が接触し、また導電繊維どうしが接触することで導電繊維全体と綿状の導電体との接触導通がはかられ、帯電繊維と導電繊維との間に容易かつ確実に電場を形成することができる。   As a result, the conductive fibers and the cotton-like conductor are in contact with each other, and the conductive fibers are in contact with each other, so that the entire conductive fiber and the cotton-like conductor are in contact with each other. An electric field can be formed easily and reliably.

また、請求項５記載の電気集塵フィルタユニットは、請求項１乃至４いずれかに記載の電気集塵フィルタユニットに対して、帯電繊維および導電繊維の少なくともどちらか一方が波のようにうねった波付き形状を有するものである。   Further, in the electrostatic dust collection filter unit according to claim 5, at least one of the charged fiber and the conductive fiber undulates like a wave with respect to the electrostatic dust collection filter unit according to any one of claims 1 to 4. It has a corrugated shape.

これにより、帯電繊維と導電繊維との間に適度の空間が設けられ、フィルタ部を通過する空気の速度が下がる。その結果として高い集塵効率と低い圧力損失を得ることができる。   Thereby, an appropriate space is provided between the charged fiber and the conductive fiber, and the speed of the air passing through the filter unit is reduced. As a result, high dust collection efficiency and low pressure loss can be obtained.

以下、本実施の形態について図面を参照しながら説明する。   Hereinafter, the present embodiment will be described with reference to the drawings.

（実施の形態１）

FIG. 1 shows an installation example in which the electric dust collection filter unit 1 of the present invention is provided in the natural air inlet 3 of the room 2. A ventilation fan 4 that exhausts room air to the outside of the room 2 and a natural air inlet 3 that takes in outside air by the amount of the exhaust air are installed on the wall of the room 2. The electric dust collection filter unit 1 is provided in the natural air supply port 3 and has a function of removing atmospheric dust in the air entering the room. Therefore, clean air enters the room 2 from the natural air inlet 3 along the ventilation direction 5 and the room 2 is filled with clean air.

次に、電気集塵フィルタユニット１の下流側に送風機６を設けた設置例を図２に示す。電気集塵フィルタユニット１の下流側には送風機６が設けられており、送風機６によって部屋の空気は電気集塵フィルタユニット１に取り込まれる。通風方向５に沿って取り込まれた空気中の大気塵は電気集塵フィルタユニット１によって空気から除去され、大気塵が除去されて清浄になった空気は部屋２の中に戻される。部屋２の空気を取り込み、大気塵を除去して部屋２に戻すことを繰り返すことで部屋２の空気は清浄化される。   Next, FIG. 2 shows an installation example in which the blower 6 is provided on the downstream side of the electric dust collection filter unit 1. A blower 6 is provided on the downstream side of the electric dust collection filter unit 1, and air in the room is taken into the electric dust collection filter unit 1 by the blower 6. Atmospheric dust in the air taken in along the ventilation direction 5 is removed from the air by the electric dust collection filter unit 1, and air purified by removing atmospheric dust is returned to the room 2. The air in the room 2 is purified by repeatedly taking in the air in the room 2, removing atmospheric dust, and returning it to the room 2.

電気集塵フィルタユニット１の構造を図３に、電気集塵フィルタユニット１を構成するイオン化手段７を図４に、別の形態のイオン化手段７を図５に、フィルタ部８を図６に示す。図３に示すように電気集塵フィルタユニット１は上流側から順にイオン化手段７、フィルタ部８で構成される。空気は通風方向に沿ってイオン化手段７、フィルタ部８の順に送り込まれる。   The structure of the electrostatic dust collection filter unit 1 is shown in FIG. 3, the ionization means 7 constituting the electrostatic dust collection filter unit 1 is shown in FIG. 4, another form of ionization means 7 is shown in FIG. 5, and the filter unit 8 is shown in FIG. . As shown in FIG. 3, the electrostatic dust collection filter unit 1 includes an ionization unit 7 and a filter unit 8 in order from the upstream side. Air is sent in the order of the ionization means 7 and the filter part 8 along the ventilation direction.

イオン化手段７はＸ線や紫外線を照射して空気分子を電離することでイオンを作るものもあるが、ここでは最も簡単な方法であるコロナ放電を用いたイオン化手段７について説明する。図４に示すイオン化手段７は線状の放電電極９とそれを挟むように設けられたアース電極板１０とで構成される。放電電極９には高圧電源１１によって高電圧が印加され、アース電極板１０にはアースが接続されて０Ｖとなっており、両者の間でコロナ放電が発生する。イオン化手段７を通過した大気塵１２はコロナ放電で発生した空気イオン１３と衝突して付着し、帯電する。ここで、イオン化手段７の寸法や印加する高電圧の極性などはコロナ放電が発生する条件であれば一切の限定はないが、一例として、２５ｍｍの間隔で設けられた２枚のアース電極板１０の中間位置に０．１ｍｍ径のタングステンワイヤーからなる放電電極９を設け、アース電極板１０をアースに接続し、放電電極９に＋６ｋＶの電圧を印加することで正のコロナ放電を発生させることができる。   Some ionization means 7 generate ions by ionizing air molecules by irradiating with X-rays or ultraviolet rays. Here, the ionization means 7 using corona discharge, which is the simplest method, will be described. The ionization means 7 shown in FIG. 4 includes a linear discharge electrode 9 and a ground electrode plate 10 provided so as to sandwich it. A high voltage is applied to the discharge electrode 9 by the high-voltage power supply 11, and the ground electrode plate 10 is connected to the ground and becomes 0V, and corona discharge occurs between them. The atmospheric dust 12 that has passed through the ionization means 7 collides with and adheres to the air ions 13 generated by corona discharge, and is charged. Here, the dimensions of the ionization means 7 and the polarity of the applied high voltage are not limited as long as corona discharge is generated, but as an example, the two ground electrode plates 10 provided at an interval of 25 mm. A discharge electrode 9 made of a tungsten wire having a diameter of 0.1 mm is provided at an intermediate position of the electrode, a ground electrode plate 10 is connected to the ground, and a voltage of +6 kV is applied to the discharge electrode 9 to generate a positive corona discharge. it can.

また、図５に示す別の形態のイオン化手段について以下説明する。図５に示すイオン化手段７は針状の放電電極９の横に一定の間隔を開けてアース電極板１０を設けた構造となっている。そして放電電極９に高電圧を印加し、アース電極板１０をアースに接続して０Ｖとすることによってコロナ放電を発生させる。発生したコロナ放電によって空気イオン１３が作られ、空気イオン１３が大気塵１２と結合して大気塵１２は帯電する。一例として胴半径１ｍｍ、先端半径２０〜１００μｍの先端が鋭利な針状電極を放電電極９として用い、その１０ｍｍ横にアース電極板１０を設け、アース電極板１０をアースに接続し、放電電極９に−６ｋＶの電圧を印加することで負のコロナ放電を発生させることができる。   Further, another form of ionization means shown in FIG. 5 will be described below. The ionization means 7 shown in FIG. 5 has a structure in which a ground electrode plate 10 is provided at a certain interval next to the needle-like discharge electrode 9. Then, a high voltage is applied to the discharge electrode 9, and the ground electrode plate 10 is connected to the ground to make 0V, thereby generating a corona discharge. Air ions 13 are generated by the generated corona discharge, and the air ions 13 are combined with the atmospheric dust 12 to charge the atmospheric dust 12. As an example, a needle-like electrode having a barrel radius of 1 mm and a tip radius of 20 to 100 μm is used as the discharge electrode 9, a ground electrode plate 10 is provided beside 10 mm, the ground electrode plate 10 is connected to the ground, and the discharge electrode 9 A negative corona discharge can be generated by applying a voltage of -6 kV to the voltage.

上記説明のように、イオン化手段７によって空気中に空気イオンが発生し、かつ空気中の大気塵は帯電する。そして空気イオンおよび帯電した大気塵を含む空気が下流側にあるフィルタ部８に送り込まれる。ここで、フィルタ部８の構成を図６に、フィルタ部８を構成する繊維集合体１４の構成を図７に、図７記載の面αによる繊維集合体１４の断面図を図８に示す。   As described above, air ions are generated in the air by the ionization means 7, and atmospheric dust in the air is charged. Air containing air ions and charged atmospheric dust is sent to the filter unit 8 on the downstream side. Here, the configuration of the filter unit 8 is shown in FIG. 6, the configuration of the fiber assembly 14 constituting the filter unit 8 is shown in FIG. 7, and the cross-sectional view of the fiber assembly 14 along the plane α shown in FIG.

支持部１６に一様に固定化された無数の帯電繊維１７と導電繊維１８によって図７に示す繊維集合体１４が形成される。フィルタ部８は図６に示すように繊維集合体１４を並列に複数並べてフィルタ部フレーム１５に納めた構造となっている。支持部１６は導電性を有すると同時に導電繊維１８と導通しており、支持部１６をアースに接続することによって導電繊維１８はアースにつながる。したがって導電繊維の電位は０Ｖになっている。   A fiber assembly 14 shown in FIG. 7 is formed by countless charged fibers 17 and conductive fibers 18 that are uniformly fixed to the support portion 16. As shown in FIG. 6, the filter unit 8 has a structure in which a plurality of fiber assemblies 14 are arranged in parallel and stored in the filter unit frame 15. The support portion 16 has conductivity and is electrically connected to the conductive fiber 18, and the conductive fiber 18 is connected to the ground by connecting the support portion 16 to the ground. Therefore, the electric potential of the conductive fiber is 0V.

繊維集合体１４は図８の断面図に示すようにコの字状の支持枠１９と押さえ棒２０によって無数の帯電繊維１７と導電繊維１８とを二つ折りにして固定している。作り方としては支持枠１９の上に帯電繊維１７と導電繊維１８を直交するように並べ、その上に押さえ棒２０を置いて両繊維が二つ折りになるように支持枠１９の中にはめ込み、その後支持枠１９を両側からかしめて押さえ棒２０が抜けないようにする。こうして支持枠１９および押さえ棒２０で形成される支持部１６に帯電繊維１７および導電繊維１８がしっかりと固定される。   As shown in the cross-sectional view of FIG. 8, the fiber assembly 14 has an infinite number of charged fibers 17 and conductive fibers 18 folded in two by a U-shaped support frame 19 and a pressing bar 20. As a manufacturing method, the charged fibers 17 and the conductive fibers 18 are arranged on the support frame 19 so as to be orthogonal to each other, and a pressing rod 20 is placed on the support fiber 19 so that both fibers are folded in two, and then inserted into the support frame 19. The support frame 19 is caulked from both sides so that the presser bar 20 does not come off. In this way, the charged fiber 17 and the conductive fiber 18 are firmly fixed to the support portion 16 formed by the support frame 19 and the presser bar 20.

ここで支持枠１９、押さえ棒２０ともに金属製で導電性を有するため、支持枠１９および押さえ棒２０によって接触固定された導電繊維１８は支持部１６との導通が得られている。したがって支持部１６をアースに接続することで導電繊維１８はアースに接続されている。更にしっかりした導通が得たい場合は支持枠１９のコの字の中に導電塗料を流し込んでおく、または、かしめた後に支持枠１９と押さえ棒２０の隙間に導電塗料を流し込んで乾燥させるといった方法をとるとよい。   Here, since both the support frame 19 and the presser bar 20 are made of metal and have conductivity, the conductive fibers 18 that are contact-fixed by the support frame 19 and the presser bar 20 are electrically connected to the support part 16. Therefore, the conductive fiber 18 is connected to the ground by connecting the support portion 16 to the ground. In order to obtain a more firm electrical conduction, a conductive paint is poured into the U-shape of the support frame 19, or after caulking, the conductive paint is poured into the gap between the support frame 19 and the holding bar 20 and dried. It is good to take.

このフィルタ部８に空気イオン１３および帯電した大気塵１２を含む空気が送り込まれる。帯電繊維１７は電荷を有する物体が付着することで帯電する性質を有する。そのため図７に示すように次から次へとやってくる空気イオン１３が付着して空気イオン１３の有する電荷が与えられる。帯電繊維１７は絶縁性であるため、導電性を有する導電繊維１８や支持部１６と接触していても電荷はなくならない。また、たとえ電荷がなくなっても上流側から常時やってくる空気イオン１３によって常に帯電した状態を保つ。   Air including air ions 13 and charged atmospheric dust 12 is fed into the filter unit 8. The charged fiber 17 has a property of being charged when an object having a charge adheres thereto. Therefore, as shown in FIG. 7, the air ions 13 coming from one to the next adhere to each other, and the charge of the air ions 13 is given. Since the charged fiber 17 is insulative, the electric charge does not disappear even if it is in contact with the conductive fiber 18 or the support portion 16 having conductivity. Moreover, even if the electric charge is lost, the charged state is always maintained by the air ions 13 constantly coming from the upstream side.

ここで、フィルタ部８を構成する帯電繊維１７と導電繊維１８が作る電場を図９に示す。帯電繊維１７は常に帯電してその表面に電荷を有した状態である。そして図９に示すようにアースに接続されている導電繊維１８には帯電繊維１７と逆極性の電荷がアースから誘電されて現れるため、両者の間に矢印で示すような電場が作られる。帯電繊維１７と導電繊維１８の間には一部が接触しながら微小な隙間が設けられている。ちなみに帯電繊維１７は絶縁性であるため導電繊維１８と接触していても全ての電荷はなくならない。そして隙間が微小であるため両者が作る電場は強く、かつ、その強い電場が、帯電繊維１７および導電繊維１８に沿って通風方向に長く奥行きのある領域全てで作られている。帯電した大気塵は電場の与えるクーロン力によって繊維に付着捕集されるが、このように強くて長い電場を作ることによって集塵性能を大きく高めている。   Here, an electric field generated by the charged fiber 17 and the conductive fiber 18 constituting the filter unit 8 is shown in FIG. The charged fiber 17 is always charged and has a charge on its surface. Then, as shown in FIG. 9, since the electric charge 18 having a polarity opposite to that of the charged fiber 17 appears from the ground in the conductive fiber 18 connected to the ground, an electric field as shown by an arrow is created between them. A minute gap is provided between the charged fiber 17 and the conductive fiber 18 while partly contacting. Incidentally, since the charged fiber 17 is insulative, even if it is in contact with the conductive fiber 18, all charges are not lost. Since the gap is very small, the electric field created by the two is strong, and the strong electric field is created along the charged fibers 17 and the conductive fibers 18 in all areas that are long and deep in the ventilation direction. The charged atmospheric dust adheres to and collects on the fiber by the Coulomb force given by the electric field, but the dust collection performance is greatly enhanced by creating such a strong and long electric field.

ここで、帯電繊維１７は一例として１０〜２００μｍの繊維径を有するポリプロピレンやポリエステル、ナイロンの繊維などが使用可能で、導電繊維１８は一例として１０〜２００μｍの繊維径を有し、繊維径中に導電性を有するカーボンが練りこまれたナイロン繊維や、表面に硫化銅が染色固定されたポリエステル繊維などが使用可能である。表面に硫化銅を染色固定した導電繊維を用いる場合、銅による抗菌作用によって捕集した菌を死滅させることができるという別の作用も得られる。   Here, for example, polypropylene, polyester, or nylon fiber having a fiber diameter of 10 to 200 μm can be used as the charged fiber 17, and the conductive fiber 18 has a fiber diameter of 10 to 200 μm as an example. Nylon fibers kneaded with conductive carbon, polyester fibers with copper sulfide dyed and fixed on the surface, and the like can be used. In the case of using a conductive fiber having copper sulfide dyed and fixed on the surface, another effect that bacteria collected by the antibacterial action of copper can be killed is also obtained.

（実施の形態２）
四角い筒状のフィルタ部フレーム１５の下流側に通風性を有する綿状の導電体２１を設け、一様に混在した帯電繊維１７と導電繊維１８とを綿状の導電体２１と垂直に接触するようにフィルタ部フレーム１５の中に入れたフィルタ部８を図１０に示す。また、構造は図１０に示すものと同じ構造で、帯電繊維１７の代わりに波のようにうねった波付きの帯電繊維２２をフィルタ部ケースの中に入れたフィルタ部８を図１１に示す。綿状の導電体２１はアースに接続されており、綿状の導電体２１と接触した導電繊維１８はアースに接続されている。 (Embodiment 2)
A cotton-like conductor 21 having air permeability is provided on the downstream side of the square cylindrical filter portion frame 15, and the uniformly mixed charged fiber 17 and conductive fiber 18 are brought into contact with the cotton-like conductor 21 perpendicularly. FIG. 10 shows the filter unit 8 placed in the filter unit frame 15 as described above. Further, FIG. 11 shows a filter unit 8 having the same structure as that shown in FIG. 10, in which a charged fiber 22 having a wave like a wave instead of the charged fiber 17 is placed in a filter case. The cotton-like conductor 21 is connected to the ground, and the conductive fiber 18 in contact with the cotton-like conductor 21 is connected to the ground.

以下の説明は、上述の図１０に示すフィルタ部８を特定して示す場合にはフィルタ部Ａ２３とし、図１１に示すフィルタ部８を特定して示す場合にはフィルタ部Ｂ２４とし、両者を総称して示す場合にはフィルタ部８として説明する。   In the following description, the filter unit A23 is specified when the filter unit 8 shown in FIG. 10 is specified, and the filter unit B24 is specified when the filter unit 8 shown in FIG. 11 is specified. In this case, the filter unit 8 will be described.

フィルタ部フレーム１５の中は繊維が密集しているため、導電繊維１８は他の導電繊維１８とも接触している。そのため全ての導電繊維を確実に綿状の導電体２１と接触させなくても、他の導電繊維との接触によって全ての導電繊維１８はアースに接続されている。結果としてフィルタ部フレーム１５に入れるだけで導電繊維１８をアースに接続することができ、帯電繊維１７と導電繊維１８との間に容易に電場を形成することができる構造となっている。   Since the fibers are densely packed in the filter unit frame 15, the conductive fibers 18 are also in contact with other conductive fibers 18. Therefore, all the conductive fibers 18 are connected to the ground by contact with other conductive fibers even if all the conductive fibers are not surely brought into contact with the cotton-like conductor 21. As a result, the conductive fiber 18 can be connected to the ground simply by being put in the filter unit frame 15, and an electric field can be easily formed between the charged fiber 17 and the conductive fiber 18.

また、フィルタ部フレーム１５の中に繊維を詰め込みすぎると空気が通る空間が極端に小さくなってしまい、フィルタ部８内部を空気は通りにくくなり、かつフィルタ部８内部を通過する空気の速度が過度に上昇してしまう。そうなると集塵効率の低下および圧力損失の上昇という性能の低下が起こってしまう。そこで波付きの帯電繊維２２を用いることで繊維どうしの間に適度な空間が設けられ、フィルタ部８の内部を通過する空気の速度が下がる。その結果高い集塵効率と低い圧力損失を得ることができる。   In addition, if the fibers in the filter unit frame 15 are packed too much, the space through which air passes becomes extremely small, making it difficult for air to pass through the inside of the filter unit 8 and the speed of the air passing through the inside of the filter unit 8 being excessive. Will rise. In such a case, a decrease in performance such as a decrease in dust collection efficiency and an increase in pressure loss occurs. Therefore, by using the corrugated charged fiber 22, an appropriate space is provided between the fibers, and the speed of the air passing through the inside of the filter unit 8 is reduced. As a result, high dust collection efficiency and low pressure loss can be obtained.

ここで上記二つのフィルタ部８を実際に作り、上流側にイオン化手段７を設けた時の集塵効率および圧力損失を測定したので結果を以下に示す。フィルタ部Ａ２３は胴回りの内寸が８０ｍｍ□、奥行きすなわち通風方向の寸法が１００ｍｍの正方形の筒状をしたフィルタ部フレーム１５の下流側開口部にスチールウールで作成した通風性を有する綿状の導電体２１を設け、もう一方、すなわち上流側の開口部から一様に混在した帯電繊維１７と導電繊維１８とを充填した構造となっている。帯電繊維１７は直径０．１３ｍｍ、長さ９０ｍｍのナイロン６１０製の直線状のフィラメントであり、また、導電繊維１８はカーボンを含有した直径０．１５ｍｍ、長さ９０ｍｍのナイロン６６製の直線状のフィラメントである。綿状の導電体２１はアースに接続されており、その結果導電繊維１８はアースに接続されている。帯電繊維１７と導電繊維１８の充填比率は１：１であり、両繊維を合わせた総充填量は２１８ｇである。   Here, the above two filter sections 8 were actually made, and the dust collection efficiency and pressure loss were measured when the ionization means 7 was provided on the upstream side. The results are shown below. The filter part A23 is a cotton-like conductive material having air permeability made of steel wool at the downstream side opening part of the filter part frame 15 in the shape of a square cylinder whose inner size around the trunk is 80 mm □ and whose depth, that is, the dimension in the ventilation direction is 100 mm. The body 21 is provided, and the charging fiber 17 and the conductive fiber 18 which are uniformly mixed from the other, that is, the opening on the upstream side, are filled. The charged fiber 17 is a linear filament made of nylon 610 having a diameter of 0.13 mm and a length of 90 mm, and the conductive fiber 18 is a linear filament made of nylon 66 having a diameter of 0.15 mm and a length of 90 mm containing carbon. It is a filament. The cotton-like conductor 21 is connected to the ground, and as a result, the conductive fiber 18 is connected to the ground. The filling ratio of the charged fiber 17 and the conductive fiber 18 is 1: 1, and the total filling amount of both fibers is 218 g.

もう一方のフィルタ部Ｂ２４は直線状の帯電繊維１７の代わりに波付きの帯電繊維２２を用いており、それ以外はフィルタ部Ａ２３と同じ構造を有する。波付きの帯電繊維２２は直径０．２１ｍｍ、長さ９０ｍｍ、波と波の頂点どうしの距離、すなわち振幅が１ｍｍのナイロン６１０製の波形状を有するフィラメントである。波付きの帯電繊維２２と導電繊維１８の充填比率はフィルタ部８Ａと同様に１：１であり、両繊維を合わせた総充填量は１３０ｇである。   The other filter part B24 uses a corrugated charging fiber 22 instead of the linear charging fiber 17, and the other filter part B24 has the same structure as the filter part A23. The corrugated charged fiber 22 is a filament having a wave shape made of nylon 610 having a diameter of 0.21 mm, a length of 90 mm, a distance between the waves and the top of the wave, that is, an amplitude of 1 mm. The filling ratio of the corrugated charged fiber 22 and the conductive fiber 18 is 1: 1 like the filter portion 8A, and the total filling amount of both fibers is 130 g.

試験の際にフィルタ部Ａ２３およびフィルタ部Ｂ２４それぞれの上流側に設けたイオン化手段７は図４に示すような線状の放電電極９でコロナ放電を起こしてイオンを発生させるタイプのものを用いた。図４に示すアルファベット小文字が示す寸法はそれぞれａ＝２０ｍｍ、ｂ＝１００ｍｍ、ｃ＝１２ｍｍ、図４とは異なるが段数＝６（すなわち放電電極９の本数６本、アース電極板１０の枚数７枚）である。線状の放電電極９はタングステン製で直径は０．１５ｍｍであり、アース電極板１０は亜鉛鋼板製で厚みは１ｍｍである。そして放電電極に５．６ｋＶの電圧を印加することでアースに接続されたアース電極板１０との間に放電電流５０μＡのコロナ放電を起こして正の空気イオンを発生している。   The ionization means 7 provided on the upstream side of each of the filter part A23 and the filter part B24 at the time of the test was of a type that generates corona discharge with a linear discharge electrode 9 as shown in FIG. 4 to generate ions. . 4 are respectively a = 20 mm, b = 100 mm, and c = 12 mm. Although different from FIG. 4, the number of steps is 6 (that is, the number of discharge electrodes 9 is 6 and the number of ground electrode plates 10 is 7). ). The linear discharge electrode 9 is made of tungsten and has a diameter of 0.15 mm, and the ground electrode plate 10 is made of galvanized steel and has a thickness of 1 mm. Then, by applying a voltage of 5.6 kV to the discharge electrode, a corona discharge with a discharge current of 50 μA is caused between the discharge electrode and the earth electrode plate 10 connected to the earth to generate positive air ions.

フィルタ部８の下流側に設けた送風機を用いてフィルタ部８の開口に対して風速１ｍ／ｓとなるように通風させた時の集塵効率と圧力損失を測定した。集塵効率はイオン化手段７の上流側とフィルタ部８の下流側それぞれにおける粒子径０．３〜０．５μｍの微小粒子の個数濃度をレーザーパーティクルカウンターで測定し、集塵効率＝１−下流側個数濃度／上流側個数濃度の式を用いて算出した。圧力損失はイオン化手段７の上流側とフィルタ部８の下流側の間の差圧を差圧計で測定した。結果を図１２に示す。   The dust collection efficiency and the pressure loss were measured when air was blown to the opening of the filter unit 8 at a wind speed of 1 m / s using a blower provided on the downstream side of the filter unit 8. The dust collection efficiency is determined by measuring the number concentration of fine particles having a particle diameter of 0.3 to 0.5 μm on the upstream side of the ionization means 7 and the downstream side of the filter unit 8 with a laser particle counter. It was calculated using the formula of number concentration / upstream number concentration. For the pressure loss, the differential pressure between the upstream side of the ionization means 7 and the downstream side of the filter unit 8 was measured with a differential pressure gauge. The results are shown in FIG.

フィルタ部Ａ２３、フィルタ部Ｂ２４ともにイオン化手段に電圧を印加して空気イオンを発生させることで大幅に集塵効率を向上させることができ、本発明の示す原理が高い効果をもたらすことを示した。特に波付きの帯電繊維２２を用いたフィルタ部Ｂ２４で非常に高い集塵効率が得られた。また、フィルタ部Ｂ２４はフィルタ部Ａ２３に比べて集塵効率が高いと同時に圧力損失が低くなっている。この結果は、繊維どうしの空間を適度に設けて空気の通り道を確保することが高い集塵効率と低い圧力損失を得るための有効な手段であることを示している。   It has been shown that the dust collection efficiency can be greatly improved by applying a voltage to the ionization means to generate air ions in both the filter part A23 and the filter part B24, and the principle of the present invention brings about a high effect. In particular, very high dust collection efficiency was obtained in the filter portion B24 using the corrugated charged fiber 22. Further, the filter part B24 has a higher dust collection efficiency and a lower pressure loss than the filter part A23. This result shows that it is an effective means for obtaining high dust collection efficiency and low pressure loss to appropriately provide a space between fibers and secure a passage for air.

本発明にかかる電気集塵フィルタユニットは、簡単に作成でき、長期間において高い清浄度を有する清浄空気が目詰まりなく得られるため、空気清浄をしながら室外空気を室内に取り入れる換気装置や室内空気を循環的に取り込んできれいにする空気清浄装置の集塵デバイスとして有用である。   The electric dust collecting filter unit according to the present invention can be easily produced and clean air having high cleanness can be obtained without clogging over a long period of time. It is useful as a dust collection device for an air purifier that takes in and cleans the water.
