Description

本発明は、空気中に含まれている臭気成分や有害物質などを分解して脱臭をおこなう脱臭装置に関する。   The present invention relates to a deodorizing apparatus for deodorizing by decomposing odor components and harmful substances contained in the air.

近年、住宅の高気密化の進展、屋外空気汚染の定常化により、居住空間内における空気質改善の要望が高まっている。空気質の中でも、タバコ煙の臭気や介護環境などにおける代謝臭気の低減、または建材から発生するVOC(揮発性有機物)に代表される有害ガス成分の除去に対するニーズは特に大きくなっている。   In recent years, the demand for air quality improvement in living spaces is increasing due to the progress of airtightness of houses and steady outdoor air pollution. Among the air qualities, there is a growing need for reducing the odor of tobacco smoke, metabolic odor in nursing care environments, etc., or removing harmful gas components typified by VOC (volatile organic substances) generated from building materials.

これらの要望に対して、従来より活性炭に代表される吸着剤による脱臭、あるいは臭気成分を他の薬剤成分と反応させ、臭気の質を変えて臭気を低減する方法が多く採用されてきた。   In response to these demands, many methods have been employed in the past to deodorize with an adsorbent typified by activated carbon, or to react odor components with other drug components to change odor quality and reduce odor.

従来技術のうち、吸着剤による脱臭や有害ガス成分の除去については、吸着量に限界があるため、長期間に亙る使用に際しては脱臭フィルタの交換は不可欠であった。また、脱臭フィルタの寿命期間中であっても、寿命末期には吸着した臭い成分が再び放出されることによる臭気発生の問題があった。   Among the prior arts, the deodorization by the adsorbent and the removal of harmful gas components are limited in the amount of adsorption, so replacement of the deodorization filter is indispensable for long-term use. In addition, even during the lifetime of the deodorizing filter, there is a problem of odor generation due to the adsorbed odor component being released again at the end of the lifetime.

一方、臭気成分を他の薬剤成分と反応させて臭気の質を変え、臭気を低減する方法については、薬剤成分の消耗による吸収薬剤の交換の煩雑さや薬剤成分を臭気環境に放出させる場合の放出量の制御に難点があった。   On the other hand, regarding the method of reducing the odor by reacting the odor component with other drug components and reducing the odor quality, it is difficult to replace the absorbed drug due to the consumption of the drug component or the release when releasing the drug component to the odor environment There was a difficulty in controlling the amount.

また、ホルムアルデヒトのような有害ガス成分の分解除去をおこなうには、酸化還元電位の高い触媒反応が必要となるが、オゾンによる酸化分解では完全分解にまで至らず中間分解生成物の段階で止まってしまうため、完全に無害化することは困難であった。   In addition, in order to decompose and remove harmful gas components such as formaldehyde, a catalytic reaction with a high oxidation-reduction potential is required, but oxidative decomposition with ozone does not lead to complete decomposition, but stops at the intermediate decomposition product stage. Therefore, it has been difficult to completely detoxify.

そしてまた、酸化チタンに代表される光触媒に紫外線を照射することにより、上記有害ガス成分を完全に分解することは可能であるが、従来は紫外線光源として、蛍光管ランプを用いており、ランプ寿命がが短いことから交換の必要があるほか、管内に水銀が含まれるため、製品廃棄時の環境負荷の観点からは好ましくなかった。   Moreover, it is possible to completely decompose the harmful gas component by irradiating a photocatalyst typified by titanium oxide with ultraviolet rays. Conventionally, however, a fluorescent tube lamp is used as an ultraviolet light source, and the lamp life is shortened. In addition to being short, it needs to be replaced, and since the mercury is contained in the tube, it was not preferable from the viewpoint of the environmental impact when the product was discarded.

これらの問題を解決するため、高電圧放電によってオゾンや紫外線を発生させ、この紫外線により活性化された光触媒モジュールで空気中に含まれている臭気成分や有害物質などの分解をおこない、高電圧放電手段により発生させたオゾンをオゾン分解手段で分解するようにした脱臭装置が提案されている(例えば、特許文献1参照)。
特開2003−339839号公報
In order to solve these problems, ozone and ultraviolet rays are generated by high-voltage discharge, and the photocatalyst module activated by the ultraviolet rays decomposes odorous components and harmful substances contained in the air, resulting in high-voltage discharge. There has been proposed a deodorizing apparatus in which ozone generated by the means is decomposed by an ozone decomposing means (see, for example, Patent Document 1).
JP 2003-339839 A

しかしながら、前記特許文献1に記載されている放電によって光触媒を励起させる方法は、脱臭能力が高いとともに、寿命が長く、性能が劣化しにくいという優れた物性を多く保有しているが、高電圧でコロナ放電をおこなうため、放電場に微細な粉塵が入り込むとスパークが発生してそのエネルギーで電極が損傷してしまい、激しいスパークでは、電極が部分的に融けて無くなってしまうという不具合があった。   However, the method of exciting the photocatalyst by electric discharge described in Patent Document 1 has many excellent physical properties such as high deodorizing ability, long life, and hardly deteriorated performance. Since corona discharge is performed, when fine dust enters the discharge field, sparks are generated and the electrodes are damaged by the energy. In severe sparks, the electrodes are partially melted and lost.

この現象を解決するためには、電極の厚さを増やすことで対策可能であるが、電極の厚さを増やすと通常のコロナ放電で起こる電極摩耗による電極材料の酸化物が空気中に放出されず、電極先端の放電部に残ってしまうという問題があった。   To solve this phenomenon, it is possible to take measures by increasing the thickness of the electrode. However, if the electrode thickness is increased, the oxide of the electrode material due to electrode wear caused by normal corona discharge is released into the air. In other words, there is a problem that it remains in the discharge part at the tip of the electrode.

本発明は上記の事情を考慮してなされたものであり、電極の放電部を支える構造部の幅寸法と厚さとの比率によって、放電摩耗による摩耗粉が放電部に付着することと、スパークによって電極が損傷することの双方を抑制でき、安定した放電を得ることができる脱臭装置を提供することを目的とする。   The present invention has been made in consideration of the above circumstances, and depending on the ratio of the width dimension and thickness of the structure part that supports the discharge part of the electrode, the wear powder due to discharge wear adheres to the discharge part, and by sparks. An object of the present invention is to provide a deodorizing apparatus that can suppress both damages of the electrode and can obtain a stable discharge.

上記課題を解決するために本発明の脱臭装置は、送風用のファンと、このファンによって送風がおこなわれる送風経路内に配置された高電圧放電によってオゾンおよび紫外線を発生させる手段と、この高電圧放電手段で発生させた紫外線による光触媒作用で空気中に含まれている臭気成分や有害物質などの分解をおこなう光触媒モジュールとを備えてなり、前記高電圧放電手段で高電圧を放電させる電極の放電部を支える構造部の幅寸法と厚さとの関係を幅寸法/厚さ>1としたことを特徴とするものである。   In order to solve the above-described problems, a deodorizing apparatus of the present invention includes a fan for blowing air, a means for generating ozone and ultraviolet rays by a high-voltage discharge disposed in a blowing path where air is blown by the fan, and the high voltage And a photocatalyst module that decomposes odorous components and harmful substances contained in the air by photocatalytic action by ultraviolet rays generated by the discharge means, and discharge of the electrode that discharges a high voltage by the high voltage discharge means. The relation between the width dimension and the thickness of the structure part supporting the part is set to width dimension / thickness> 1.

本発明の構成によれば、放電摩耗による摩耗粉が放電部に付着する現象を防ぐとともに、異物侵入などによるスパークによって電極が損傷することを抑制できる。   According to the configuration of the present invention, it is possible to prevent the abrasion powder due to discharge wear from adhering to the discharge part, and to suppress the electrode from being damaged by sparks due to foreign matter intrusion or the like.

以下、図面に基づき本発明の1実施形態について説明する。図1は、家庭内の厨房におけるレンジフードなどに取り付けた脱臭装置(1)の概略図であり、脱臭をおこなう対象エリアに設けた風路(2)内に配設している。この脱臭装置(1)は、光触媒モジュール(3)とオゾン分解触媒(4)とを備え、前記風路(2)内を流通する空気に含まれる臭い分子や有機物質を吸着し脱臭するものである。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of a deodorizing device (1) attached to a range hood or the like in a kitchen in a home, and is arranged in an air passage (2) provided in a target area where deodorization is performed. This deodorization apparatus (1) includes a photocatalyst module (3) and an ozone decomposition catalyst (4), and adsorbs and deodorizes odor molecules and organic substances contained in the air flowing through the air passage (2). is there.

光触媒モジュール(3)は、ガラスやセラミックスなどの無機材料からなる基体の表面に、酸化チタンに代表される光触媒粒子を固定した光触媒フィルタ(5)を2枚隣接し、この2枚の光触媒フィルタ(5a)(5b)間には、放電電極(6)を立設するとともに、前記光触媒フィルタ(5a)(5b)の風上と風下側には、メッシュ電極からなる対極(7a)(7b)をそれぞれ配置することで構成されている。   In the photocatalyst module (3), two photocatalyst filters (5) in which photocatalyst particles represented by titanium oxide are fixed are adjacent to the surface of a substrate made of an inorganic material such as glass or ceramics. Between 5a and 5b, a discharge electrode (6) is erected, and counter electrodes (7a) and (7b) comprising mesh electrodes are provided on the windward and leeward sides of the photocatalytic filters (5a) and (5b). It is configured by arranging each.

なお、前記光触媒モジュール(3)における光触媒フィルタ(5)は、必ずしも2枚隣設せずとも、臭気成分や有害物質が比較的少ない場合には、1枚の光触媒フィルタの前後に対極(7)と放電電極(6)を設ける構成でもよい。   The photocatalyst filters (5) in the photocatalyst module (3) are not necessarily provided adjacent to each other, but when there are relatively few odor components and harmful substances, the counter electrode (7) is provided before and after one photocatalyst filter. And a discharge electrode (6) may be provided.

(8)は電源装置であり、トランスなどの高電圧発生部(9)により前記放電電極(6)と各対極(7a)(7b)との間に直流高電圧を印加するものであって、この構成により、放電電極(6)と対極(7a)(7b)は紫外線発生用の放電手段として機能し、双方の電極間に放電が起きて波長が380nm以下である紫外線が発生する。また、(10)はファンであり、風路(2)内に前記ファン(10)を風下側として配列することで空気流通を促進し、脱臭作用を助長するものであり、前記ファン(10)の風上側に集塵フィルタを配置してもよい。   (8) is a power supply device for applying a DC high voltage between the discharge electrode (6) and each counter electrode (7a) (7b) by a high voltage generator (9) such as a transformer, With this configuration, the discharge electrode (6) and the counter electrodes (7a) and (7b) function as a discharge means for generating ultraviolet rays, and discharge occurs between both electrodes to generate ultraviolet rays having a wavelength of 380 nm or less. Further, (10) is a fan, and the fan (10) is arranged on the leeward side in the air passage (2) to promote air circulation and promote deodorization. The fan (10) A dust collection filter may be arranged on the windward side of the.

上記脱臭装置(1)は、電源装置(8)に通電して高電圧発生部(9)から放電電極(6)と各対極(7a)(7b)との間に高電圧を与えることで電極間に放電が起き、発生した紫外線が光触媒フィルタ(5a)(5b)に照射されることで光触媒を活性化させ、水酸化ラジカル(遊離基)の強い酸化作用で光触媒フィルタ(5a)(5b)の表面に吸着した臭気ガス成分や有機化合物の結合を分解し、無臭化若しくは低臭気化することで脱臭するものであり、また、菌細胞膜を脆化させ抗菌をおこなうとともに、酸化分解作用によって光触媒フィルタ(5a)(5b)表面上の微生物、特に好気性細菌の繁殖を抑制し汚れを分解する。   The deodorizing device (1) is configured to supply a high voltage between the discharge electrode (6) and each counter electrode (7a) (7b) from the high voltage generating unit (9) by energizing the power supply device (8). The photocatalyst filter (5a) (5b) is activated by irradiating the photocatalyst filter (5a) (5b) in the meantime, and the photocatalyst is activated by the strong oxidizing action of hydroxyl radicals (free radicals). Decomposes by decomposing bonds of odorous gas components and organic compounds adsorbed on the surface and deodorizing them by deodorizing or reducing odor. In addition, the cell membrane is embrittled and antibacterial, and it is photocatalyst by oxidative decomposition. The filter (5a) (5b) suppresses the growth of microorganisms, particularly aerobic bacteria on the surface, and decomposes dirt.

そしてまた、この放電電極(6)と対極(7)が放電すると、紫外線とともにオゾンが発生するため、前記光触媒モジュール(3)は、紫外線による活性酸素の発生で有機物質を分解させる機能とともに、オゾン発生手段としても機能するものであり、臭気成分を含んだ空気を発生したオゾンと混合し反応させることで臭気成分を酸化分解し脱臭することができる。   Further, when the discharge electrode (6) and the counter electrode (7) are discharged, ozone is generated together with ultraviolet rays. Therefore, the photocatalyst module (3) has a function of decomposing organic substances by generation of active oxygen due to ultraviolet rays, and ozone. It also functions as a generating means, and the odor component can be oxidatively decomposed and deodorized by mixing and reacting with the generated ozone with the air containing the odor component.

光触媒モジュール(3)の風下側には、所定距離を空けて2酸化マンガンを主体にしたハニカム形状の焼結体からなる前記オゾン分解触媒(4)を設置しており、臭気物質と反応しないでそのまま流下する余剰オゾンを分解するようにしている。なお、オゾン発生手段は、上記の光触媒モジュール(3)によるものだけでなく、沿面放電電極と高電圧トランスを組み合わせたものや電解方式によるものでもよい。   On the leeward side of the photocatalyst module (3), the ozone decomposition catalyst (4) made of a honeycomb-shaped sintered body mainly composed of manganese dioxide is provided at a predetermined distance, and does not react with odorous substances. The excess ozone flowing down is decomposed as it is. Note that the ozone generating means is not limited to the photocatalyst module (3), but may be a combination of a creeping discharge electrode and a high voltage transformer or an electrolytic system.

しかして、前述のように、スパークによる放電電極(6)の損傷は、導電性の異物の混入などにより空気による絶縁が破壊されることによって発生するものであり、スパーク放電のエネルギーが非常に大きいために、放電部、さらには構造部までもが高温になり、素材を酸化させる現象である。この現象は、ときには、電極素材自体を融かしてしまうことがあり、電極構造によっては、電極が部分的に無くなることもあって、これを防止するためには、スパーク放電を受ける断面積を増やし、部分的に損傷しても電極部が無くならないようにするのが有効である。   As described above, damage to the discharge electrode (6) due to spark is caused by destruction of insulation by air due to mixing of conductive foreign matters, etc., and the energy of spark discharge is very large. Therefore, the discharge part and even the structure part become a high temperature, and this is a phenomenon that oxidizes the material. This phenomenon sometimes melts the electrode material itself, and depending on the electrode structure, the electrode may be partially lost.To prevent this, the cross-sectional area that receives the spark discharge is reduced. It is effective to increase and prevent the electrode portion from being lost even if it is partially damaged.

放電電極(6)の断面積を増やすには、構造部の幅寸法を増やす方法と厚さを増やす方法とがあるが、幅寸法を増やすだけでは厚さ方向へ放電エネルギーが貫通してしまい、電極放電部の破壊を防ぐ効果がないとともに、幅が広くなると風路を狭めることになるため、脱臭装置(1)としての性能に影響を与えることから、厚さを増大することが有効である。   In order to increase the cross-sectional area of the discharge electrode (6), there are a method of increasing the width dimension of the structure part and a method of increasing the thickness, but the discharge energy penetrates in the thickness direction only by increasing the width dimension, Since there is no effect of preventing the electrode discharge part from being destroyed and the width is widened, the air passage is narrowed. Therefore, the performance as the deodorizing device (1) is affected, so increasing the thickness is effective. .

ただし、厚さを増やして熱移動を3次元的に増加させることによって、電極が放電により摩耗する現象に変化が現れる。摩耗した電極の素材は気体になり、空気中に放出されて酸化物になるが、熱の移動が増加することによって摩耗した電極の素材が空気中に放出されず、電極上で酸化物になってしまうと推測される現象が生じる。   However, by increasing the thickness and increasing the heat transfer three-dimensionally, a change appears in the phenomenon that the electrode is worn by discharge. The worn electrode material becomes a gas that is released into the air and becomes oxide, but due to increased heat transfer, the worn electrode material is not released into the air and becomes oxide on the electrode. A phenomenon that is presumed to occur occurs.

この現象によって、電極の放電部には、酸化物が堆積して電気抵抗を持つようになるため、図2に示すように、時間経過による放電時の消費電力量の変化に対して、前記経時変化に対応する脱臭装置(1)からのオゾン発生量の変化を表す図3に示すように、時間の経過とともに、電力を消費するものの実際の放電作用は阻害され、少なくなってしまう現象が発生するものであり、その結果、光触媒モジュール(3)の光触媒による脱臭分解性能も低下していくことになる。   As a result of this phenomenon, oxide is deposited on the discharge portion of the electrode and has an electric resistance. Therefore, as shown in FIG. As shown in FIG. 3, which shows a change in the amount of ozone generated from the deodorizing apparatus (1) corresponding to the change, over time, although the electric discharge is consumed, the actual discharge action is hindered and reduced. As a result, the deodorizing and decomposing performance of the photocatalyst module (3) by the photocatalyst also decreases.

前記放電電極(6)は、その平面図を図4に示すように、長方形状で0.3mm厚とした銅、ステンレス、タングステンなどの薄板金属(6a)の内面側をエッチングして断面が幅寸法(w)を1.0mm、厚さ(t)を0.3mmのワイヤ状にした格子(6b)により構造部を成形し、図5にその詳細図を示すように、形成される多数の角穴(6c)の各辺の中央部から水平面の鉛直方向に突出する尖端状の放電部(6d)を設けたものであり、前記尖端状の放電部(6d)により放電しやすい形状となっている。   As shown in FIG. 4, a plan view of the discharge electrode (6) is formed by etching the inner surface side of a thin plate metal (6a) such as copper, stainless steel, tungsten, etc., having a rectangular shape and a thickness of 0.3 mm. A structural part is formed by a grid (6b) having a wire shape with a dimension (w) of 1.0 mm and a thickness (t) of 0.3 mm. As shown in detail in FIG. A point-like discharge part (6d) protruding in the vertical direction of the horizontal plane from the central part of each side of the square hole (6c) is provided, and is shaped to be easily discharged by the point-like discharge part (6d). ing.

一方、対極(7a)(7b)は、特に図示しないが、風路(2)を流れる空気を通し、また電気を通すために、前記放電電極(6)と同様にステンレスなどの薄板をエッチングすることでメッシュ電極としたものであり、このメッシュ電極は製造が容易なためコスト的にも安価となる利点がある。   On the other hand, the counter electrodes (7a) and (7b), although not particularly shown, etch a thin plate such as stainless steel in the same manner as the discharge electrode (6) in order to pass air flowing through the air passage (2) and to pass electricity. Thus, the mesh electrode is easy to manufacture and has an advantage that the cost is low.

図6に放電電極(6)の構造部である前記格子(6b)の幅寸法(w)と厚み寸法(t)を、資料1〜5のように5種類に変化させたときの酸化物付着の有無とスパーク時の損傷状態について実験した結果を示す。この結果から理解されるように、放電による酸化物の有無は、電極の厚さ(t)に依存しており、資料1、3のように厚さ(t)が0.5mmでは酸化物が堆積するが、資料2、4および5のように厚さ0.3mmおよび厚さ0.1mmと薄い場合は酸化物の堆積が認められなかった。   FIG. 6 shows oxide adhesion when the width (w) and thickness (t) of the lattice (6b), which is the structure of the discharge electrode (6), are changed to five types as shown in materials 1-5. The results of experiments on the presence or absence of damage and the state of damage during sparking are shown. As can be understood from this result, the presence or absence of oxide due to discharge depends on the thickness (t) of the electrode. In the case of deposition, oxide deposition was not observed when the thickness was as thin as 0.3 mm and 0.1 mm as in Samples 2, 4 and 5.

一方、0.1mm厚や0.3mm厚で酸化物の堆積が認められなくても、資料3、4のように幅寸法(w)が0.3mmでは、スパーク時に電極溶断が発生する不具合があったが、資料2のように、電極厚さ(t)が0.3mmで格子(6b)の幅寸法(w)が0.5mmの構造部では酸化物の堆積がなく、スパーク時の損傷についても放電部は変形したが電極溶断は発生せず採用可能な判定を得た。また、資料5の、電極厚さ(t)が0.3mmで格子(6b)の幅寸法(w)が1.0mmの構造部では酸化物の堆積がないとともにスパーク時の損傷についても電極溶断は発生せず、良好な結果を得たものである。すなわち、電極厚さが0.3mm以下で構造部の幅寸法が0.5mm以上であれば格子(6b)は溶断せず放電電極(6)として良好な判定結果が得られた。   On the other hand, even if oxide deposition is not recognized at 0.1 mm thickness or 0.3 mm thickness, if the width dimension (w) is 0.3 mm as shown in Documents 3 and 4, there is a problem that electrode fusing occurs during sparking. However, as shown in Document 2, in the structure where the electrode thickness (t) is 0.3 mm and the width (w) of the grating (6b) is 0.5 mm, there is no oxide deposition and damage during sparking. In addition, the discharge part was deformed, but electrode fusing did not occur. In addition, in the structure of Sample 5 where the electrode thickness (t) is 0.3 mm and the width (w) of the lattice (6b) is 1.0 mm, there is no oxide deposition and the electrode is blown out for damage during sparking. Does not occur, and good results are obtained. That is, when the electrode thickness was 0.3 mm or less and the width of the structure portion was 0.5 mm or more, the grid (6b) was not melted and a good determination result was obtained as the discharge electrode (6).

これらのことから、高電圧放電手段で高電圧を放電させる電極(6)において、酸化物の堆積を抑制し、またスパーク時の電極溶断を防ぐことができる構造部(6b)の幅寸法と厚さとの関係は、構造部の幅寸法が厚み寸法より大きいか、また同寸法である組み合わせ、すなわち、幅寸法(w)/厚さ(t)>1の関係であり、特に、厚み寸法は、0.3mm以下であり、幅寸法は、0.5〜1.0mmであった。   For these reasons, in the electrode (6) for discharging a high voltage by the high-voltage discharge means, the width and thickness of the structure (6b) that can suppress oxide deposition and prevent electrode fusing during sparking. Is a combination in which the width dimension of the structure portion is larger than or equal to the thickness dimension, that is, a relation of width dimension (w) / thickness (t)> 1, and in particular, the thickness dimension is It was 0.3 mm or less, and the width dimension was 0.5-1.0 mm.

したがって、電極の放電部(6d)を支える構造部である格子(6b)の断面形状を上記幅寸法(w)と厚さ(t)との関係にすることによって、放電摩耗による摩耗粉が酸化物として放電部(6d)に付着する酸化物の堆積現象と、異物の侵入などによるスパークによって電極の構造部である格子(6b)の溶断など損傷することとの双方の不具合を抑制でき、安定した放電現象を得ることができるものである。   Therefore, by setting the cross-sectional shape of the lattice (6b), which is a structural part supporting the discharge part (6d) of the electrode, to the relationship between the width dimension (w) and the thickness (t), the wear powder due to the discharge wear is oxidized. It is possible to suppress both problems such as oxide deposition that adheres to the discharge part (6d) as an object and damage such as fusing of the lattice (6b) that is a structure part of the electrode due to sparks due to intrusion of foreign matter, etc. The discharge phenomenon can be obtained.
