Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、空気中の悪臭を除去するための空気 清浄機に使用する脱臭及除じん用エレメントに関 するもので、特に、圧損失が低く、処理容量が大 きい場合に好適な空気清浄用エレメントである。TECHNICAL FIELD The present invention relates to a deodorizing and dust-removing element used in an air cleaner for removing a malodor in the air. It is an air cleaning element that is suitable for low and large processing capacity.

〔従来の技術〕 空気中の悪臭成分を吸収除去するために使用す る空気清浄機の吸着エレメントとしては、粒状活 性炭を充填した吸着層、繊維状活性炭を抄紙して コルゲーション加工・積層したフィルター、ガラ ス繊維もしくは合成繊維等の不織布に、バインダ ーを使用して活性炭微粉末を付着せしめ、コルゲ ーション加工・積層したフィルター等が使用され てきた。 [Prior art] As an adsorption element of an air cleaner used to absorb and remove malodorous components in the air, an adsorption layer filled with granular activated carbon and fibrous activated carbon were made into paper and corrugated and laminated. Filters, corrugation-processed and laminated filters have been used in which fine powder of activated carbon is attached to a non-woven fabric such as a filter or glass fiber or synthetic fiber using a binder.

しかし、最近空気清浄機用の吸着エレメントは 風量が多い状態で使用されるため、特に圧損失が 低く、しかも、比較的吸着効率も高いものが要求 されるようになってきている。従って、従来のフ ィルターでは圧損失の点で不適当である。 However, recently, adsorption elements for air purifiers are used with a large amount of air flow, so that there is a demand for particularly low pressure loss and relatively high adsorption efficiency. Therefore, the conventional filter is not suitable in terms of pressure loss.

また、空気中の浮遊粉じんを除去するため、従 来静電空気清浄機或いは電気集じん機が使用され ていた。これらはコロナ放電によつて粉じんの粒 子を荷電させ、これらの粒子を反対の電荷を有す る電極またはフィルターによつて補集除去するも のである。しかし、コロナ放電により、粉じん粒 子を荷電するためには数KV或いは数10KVの高電 圧が必要となり、取扱上危険があるのみならず、 火災が発生するおそれもあった。このため高電圧 を必要としない集じん装置への要望が高く、静電 効果によらないフィルターも種々提案されたが、 たばこの煙を含有する場合が多い一般の室内また は車内の空気では、径1μm以下の粉じんも補集 する必要があるため、圧損失が非常に高いフィル ターが必要となることは避けられなかった。従っ て、この方式では低圧損失でしかも効率よく粉じ ん微粒子を除去することは極めて困難であつた。 In addition, electrostatic air cleaners or electrostatic precipitators have been used in the past to remove airborne dust. They charge dust particles by a corona discharge and collect and remove these particles by electrodes or filters with opposite charges. However, due to corona discharge, a high voltage of several KV or several tens of KV is required to charge the dust particles, which is not only dangerous in handling but also may cause a fire. Therefore, there is a strong demand for dust collectors that do not require high voltage, and various filters that do not rely on the electrostatic effect have been proposed. Since it is necessary to collect dust with a diameter of 1 μm or less, it is unavoidable that a filter with a very high pressure loss is required. Therefore, with this method, it was extremely difficult to remove dust particles efficiently with low pressure loss.

〔発明が解決しようとする課題〕 従来最も多く使用されている粒状活性炭吸着層 は、通気抵抗が大きいため、風量を大きくして使 用するためには不適当である。そこで、圧損失を 低下させるため、シート状吸着剤をコルゲーショ ン加工して巻き込んだものがしばしば使用されて いる。 [Problems to be Solved by the Invention] The granular activated carbon adsorption layer which has been used most frequently in the past is not suitable for use with a large air volume because it has a large ventilation resistance. Therefore, in order to reduce the pressure loss, a sheet-shaped adsorbent that is corrugated and rolled up is often used.

しかし、コルゲーションした後、波形シートと 平面シートを貼り合わせるために使用した接着剤 が活性炭層に浸み込んで活性炭表面を覆うため、 吸着能力が阻害されていた。従って、風量が多い 状態で使用しても、圧損失が小さく且つ活性炭の 吸着能力が低下しないような、吸着エレメントが 要望されていた。 However, after corrugation, the adhesive used to bond the corrugated sheet and the flat sheet permeated the activated carbon layer and covered the surface of the activated carbon, which hindered the adsorption ability. Therefore, there has been a demand for an adsorption element that has a small pressure loss and does not deteriorate the adsorption capacity of activated carbon even when used in a state where the air volume is large.

また、室内或いは車内の空気を浄化するために は、悪臭の他たばこの煙のような微細粉じんを除 去する必要がある。 In addition, in order to purify the air inside or inside the vehicle, it is necessary to remove fine dust such as cigarette smoke and odor.

〔問題点を解決するための手段〕 本発明者等は、活性炭の吸着能力を保持して、 しかも圧損失を極めて低くすることが出来る吸着 エレメントの基材として、編物の一部が厚くなっ て、その表面に多数の畝状の形状を有するものが 適していることを見出した。 [Means for Solving Problems] The inventors of the present invention have confirmed that a part of a knitted fabric is thick as a base material of an adsorption element capable of retaining the adsorption ability of activated carbon and extremely reducing pressure loss. , And found that those having a large number of ridges on the surface are suitable.

更に、たばこの煙のような微細粉じんを、安全 ・低コストで除去するためには、エレクトレット ・フィルターが好適であることが知られていたが、 この両者を組み合わせると、極めて効果的である ことを見出して本発明に到達した。 Furthermore, it has been known that an electret filter is suitable for removing fine dust such as cigarette smoke safely and at low cost, but it is extremely effective to combine both of them. And found the present invention.

すなわち、表面が、畝状に凸部となつている部 分を有する編物に、吸着材を添着し、これを積層 または、巻いて円柱状とせしめてなる空気清浄用 エレメント及び、上記のエレメントと、エレクト レット・フィルターを複合せしめた空気清浄用エ レメントである。 That is, an adsorbent is attached to a knitted fabric whose surface has a ridge-like convex portion, and the adsorbent is laminated or wound to form a columnar air-cleaning element and the above element. This is an air cleaning element that combines an electret filter.

以下、本発明について詳しく説明する。 Hereinafter, the present invention will be described in detail.

本発明において吸着剤を添着せしめる基材は、 表面が、畝状に凸部となっている部分を有する編 物を使用する必要がある。畝状に凸部となってい る部分とは、例えば、第1図に示すように畑の表 面の畝のように線状に盛り上がった形状を指して いるが、畝の形は直線でも曲線でもまた不規則な 形でもよい。また、畝の断面の形も矩形でも、か まぼこ形でも、不規則な形でもよい。例えば、ダ ブルラッセル編のような構造の編地を使用すれば、 容易にこのような形状とすることが出来る。編地 ば特定の構造に限定しないが、空気との接触面積 を大きく且つ吸着剤の添着量を大きく出来るもの が好ましい。 In the present invention, as the base material to which the adsorbent is attached, it is necessary to use a knitted fabric having a ridge-shaped convex portion on the surface. The ridge-shaped convex portion refers to a linearly raised shape such as a ridge on the surface of the field as shown in Fig. 1, but the ridge shape may be straight or curved. But it can also be irregular. The shape of the ridge cross section may be rectangular, semicylindrical, or irregular. For example, if a knitted fabric having a structure such as a double russell knit is used, such a shape can be easily obtained. The knitted fabric is not limited to a specific structure, but it is preferable that the knitted fabric has a large contact area with air and a large adsorbent loading.

また、このような構造のシートを積層したり、 巻き込んだりしたとき畝のように盛り上がった部 分が倒れるのを防ぐため、畝の頂上に畝を相互に 繋ぐための少量の糸が畝と直角の方向にあっても 良い。 In addition, in order to prevent the raised parts such as ridges from falling when laminating or winding sheets with such a structure, a small amount of thread for connecting the ridges to each other at the top of the ridges is perpendicular to the ridges. It may be in the direction of.

吸着剤は活性炭、ゼオライト、植物精油等空気 中の悪臭除去に効果があるものならば、何でもよ い。特に、活性炭は無極性吸着剤として極めて優 れた吸着性を有する特異な材質で、殆どすべての ガス状物質に対して高い吸着性を示すため好適で ある。しかし、活性炭もたばこの煙に含まれてい るアセトアルデヒド、アンモニア、低級アミン、 炭化水素、硫化水素等に対する吸着能力は充分で ない。従って、活性炭の吸着性を改善するため、 燐酸、りんご酸、アスコルビン酸等その他の物質 を添着した活性炭を使用してもよい。 Any adsorbent can be used as long as it is effective for removing malodor in the air such as activated carbon, zeolite, and plant essential oil. In particular, activated carbon is a unique material having extremely excellent adsorptivity as a non-polar adsorbent, and is suitable because it exhibits high adsorptivity for almost all gaseous substances. However, activated carbon also has insufficient adsorption capacity for acetaldehyde, ammonia, lower amines, hydrocarbons, hydrogen sulfide, etc. contained in tobacco smoke. Therefore, in order to improve the adsorptivity of activated carbon, activated carbon impregnated with other substances such as phosphoric acid, malic acid, ascorbic acid may be used.

これらの吸着剤を編地に添着させる方法は特に 限定しないが、バインダーを使用する方法が最も 簡便である。しかし、バインダーを使用する場合 はある程度の吸着能力の低下は避けられないが、 比較的吸着能力の低下の少ないラテックス系のも のが好ましい。使用する活性炭・その他のガス吸 収剤の粒度はラテックスと混合したときの分散安 定性の点から、100メッシュパス以下、好ましく は、300メッシュパス以下にすると、添着性が良 好な吸収剤懸濁液を調製できる。 The method of attaching these adsorbents to the knitted fabric is not particularly limited, but the method of using a binder is the simplest. However, when a binder is used, it is inevitable that the adsorption capacity will decrease to some extent, but it is preferable to use a latex type in which the adsorption capacity is relatively small. The particle size of the activated carbon and other gas absorbers used is 100 mesh pass or less, preferably 300 mesh pass or less, from the viewpoint of dispersion stability when mixed with latex, and the adsorbent suspension with good adherability is used. A suspension can be prepared.

本発明は吸着剤を添着した、表面が畝状の凸部 を有する編物を、積層または、巻いて円柱状とし て使用する必要がある。例えば、第2図または第 3図に示すような形状である。これらの形状は必 要に応じて変形して使用することができる。例え ば、第2図の場合側面が台形になったり、抉られ た部分を有する形、また第3図では楕円形、型に 押し込んで直方体に成形したもの等である。 In the present invention, it is necessary to laminate or wind a knitted fabric having a ridge-shaped convex portion with an adsorbent attached thereto for use as a column. For example, the shape is as shown in FIG. 2 or FIG. These shapes can be modified and used as needed. For example, in the case of FIG. 2, the side surface has a trapezoidal shape or a shape having a gouged portion, and in FIG. 3, the shape is an elliptical shape, which is pressed into a mold to form a rectangular parallelepiped.

また、積層する場合にはその構造から、コルゲ ーションして積層する場合と較べて、層間の接着 面積が大分小さくなるので、吸着能力の低下が少 なくなる。 In addition, when laminated, the adhesive area between layers is much smaller due to its structure, as compared with the case of corrugated laminated layers, and therefore the decrease in adsorption capacity is small.

前述のような形状にすると、大きな風量を流し た場合でも、圧損失が非常に低く且つ編物の組織 内部にも風が通り、空気が吸着剤と接触するため に脱臭効果が優れている。 With the above-mentioned shape, even when a large amount of air is blown, the pressure loss is very low, the air passes through the inside of the knitted fabric, and the air comes into contact with the adsorbent, so that the deodorizing effect is excellent.

本発明の空気清浄用エレメントにはエレクトレ ット・フィルターが組み込まれている。このフィ ルターの材質は電気的に分極されていて、換言す れば常に一定の静電荷をもった状態となっている。 The air purifying element of the present invention incorporates an electret filter. The material of this filter is electrically polarized, in other words, it always has a constant electrostatic charge.

従って、たばこの煙のような径1μm以下の極微 粒子は通常正電荷をもっているため、エレクトレ ット・フィルターの負電荷を有する部分に吸引さ れる。従って、低圧損失で、効率よく除去しうる。Therefore, since ultrafine particles with a diameter of 1 μm or less, such as cigarette smoke, usually have a positive charge, they are attracted to the negatively charged portion of the electret filter. Therefore, it can be efficiently removed with a low pressure loss.

このような極微粒子は通常の濾過によつて除去す ることは相当困難で、また高い圧損失を必要とす る。エレクトレット・フィルターは通常エレクト レット処理により分極化して誘電体となる材質、 例えばポリエチレン、ポリプロピレン、ポリエス テル、ポリ弗化ビニル等のポリマーよりつくられ る。永久的に分極化する方法として種々の方法が 知られているが、通常誘電体を電極板にはさみ軟 化点付近迄昇温し、直流高電圧を加えた状態で室 温迄徐冷することにより作られる。またこの分極 状態は数年間は持続されるため長期間にわたって 極微粒子除去機能を有する。しかも、使用する場 合高電圧をかける必要がないので、取扱が容易で 火災を発生する危険がなく安全性が高い。Such ultrafine particles are considerably difficult to remove by ordinary filtration and require high pressure loss. The electret filter is usually made of a material which is polarized by electret treatment to become a dielectric, for example, a polymer such as polyethylene, polypropylene, polyester or polyvinyl fluoride. Various methods are known as permanent polarization methods. Usually, a dielectric is sandwiched between electrode plates to raise the temperature to near the softening point and then gradually cool to room temperature with a high DC voltage applied. Made by. Moreover, since this polarization state lasts for several years, it has the function of removing ultrafine particles for a long period of time. Moreover, since it is not necessary to apply high voltage when using it, it is easy to handle, there is no danger of fire, and safety is high.

〔作用・効果〕 本発明の空気清浄エレメントは前述のように、 空気に流通路に沿って、多数のチューブ状の通路 を有するため、大きな風量の空気を流した場合で も圧損失が非常に低く、且つ編物の組織内部にも 風が通り、空気が吸着剤と接触する面積が大きい ため、室内或いは車内の空気を高速で循環させた 場合の脱臭効果が優れている。また、普通の活性 炭の他、たばこの煙に含まれているアセトアルデ ヒド、アンモニア、低級アミン等に対する吸着能 力を向上させるため燐酸、りんご酸、アスコルビ ン酸等を添着した活性炭を使用すると、たばこの 悪臭除去に極めて好適である。 [Operation / Effect] As described above, the air purification element of the present invention has a large number of tubular passages along the flow passage in the air, so that even if a large amount of air is flowed, the pressure loss is extremely high. Since it is low, and the air passes through the inside of the knitted fabric, and the area where air contacts the adsorbent is large, the deodorizing effect is excellent when the air in the room or vehicle is circulated at high speed. In addition to ordinary activated carbon, if activated carbon impregnated with phosphoric acid, malic acid, ascorbic acid, etc. is used in order to improve the adsorption capacity for acetaldehyde, ammonia, lower amine, etc. contained in cigarette smoke, It is extremely suitable for removing the bad odor of cigarettes.

更に、本発明は、エレクトレット・フィルター を複合させてあるため、低圧損失で径1μm以下 の空気中の浮遊粉じんを効率よく除去することが 出来る。従って、たばこの煙の除去効果も高く、 従来法のように高電圧を必要としないため取扱が 容易で且つ安全性が高い。 Further, in the present invention, since the electret filter is combined, it is possible to efficiently remove the suspended dust in the air having a diameter of 1 μm or less with a low pressure loss. Therefore, it is highly effective in removing cigarette smoke and does not require high voltage as in the conventional method, so it is easy to handle and highly safe.
