Description

本発明は空気清浄装置に係り、特に、居室内の空気浄化に好適な空気清浄装置に関する。   The present invention relates to an air purification device, and more particularly to an air purification device suitable for air purification in a living room.

従来、建物内部、室内、車中などの大気の殺菌、脱臭等を行う空気清浄装置として、たとえば、特許文献1に記載のものが提案されている。   2. Description of the Related Art Conventionally, as an air cleaning device for sterilizing, deodorizing, or the like of the atmosphere inside a building, indoors, or inside a vehicle, for example, the one described in Patent Document 1 has been proposed.

この空気清浄装置は、紫外線を照射することによりオゾンを発生させるオゾン灯を、両端部を開口した筒状体で包囲し、この筒状体の少なくとも一端側に、筒状体の内部に強制的に大気の流れを生じさせる手段(ファン)を設けたものである。   This air cleaning device surrounds an ozone lamp that generates ozone by irradiating ultraviolet rays with a cylindrical body that is open at both ends, and is forced into at least one end side of the cylindrical body inside the cylindrical body. Is provided with means (fan) for generating an air flow.

この種の空気清浄装置によれば、筒状体で包囲したオゾン灯から紫外線が照射されると、オゾンが発生する。このオゾンは酸素分子と酸素原子に自己分解(自然分解)して、酸素原子の強酸化作用により殺菌や脱臭などがなされる。   According to this type of air cleaning device, ozone is generated when ultraviolet rays are irradiated from an ozone lamp surrounded by a cylindrical body. This ozone is self-decomposed (natural decomposition) into oxygen molecules and oxygen atoms, and is sterilized and deodorized by the strong oxidizing action of oxygen atoms.

特開2002−224204号公報JP 2002-224204 A

ところで、前記特許文献1に記載の空気清浄装置では、オゾンの酸素分子と酸素原子への分解を自然分解に委ねているものの、オゾンは不安定なため容易に酸素分子と酸素原子に分解するとされている。しかし、一概にそうは言い切れず、たとえば、筒状体内の気圧、温度、湿度、流量、流速などの条件が様々に変動すると、オゾンが居室内等に放出されるおそれを有する。そのため、居室内の換気を図ったり、居室内等のオゾン濃度を確認するなどの煩雑なオゾン管理が必要になる。   By the way, in the air cleaning device described in Patent Document 1, although ozone is naturally decomposed into oxygen molecules and oxygen atoms, since ozone is unstable, it is easily decomposed into oxygen molecules and oxygen atoms. ing. However, this is generally not the case. For example, when conditions such as atmospheric pressure, temperature, humidity, flow rate, and flow velocity in the cylindrical body fluctuate variously, ozone may be released into the living room. For this reason, complicated ozone management such as ventilation in the living room or confirmation of the ozone concentration in the living room is required.

本発明はこのような実情に鑑みてなされたものであって、その目的とするところは、オゾンの居室内等への排出(放出)を確実に防止して、居室内等の換気を図ったり、居室内等のオゾン濃度を確認するなどの煩雑なオゾン管理を不要にし得る空気清浄装置を提供することにある。   The present invention has been made in view of such circumstances, and the object of the present invention is to reliably prevent the discharge (release) of ozone into the living room and the like to ventilate the living room and the like. An object of the present invention is to provide an air cleaning device that can eliminate the need for complicated ozone management such as checking the ozone concentration in a living room.

前記目的を達成するために、本発明に係る空気清浄装置は、上流端に空気吸込口を開口し下流端に排気手段を装備し、体内に前記空気吸込口と排気手段を連通させる通気路を設けた筺体を備え、前記通気路の上流側にオゾン発生手段が配置され、その下流側には、通気路のオゾンを酸素分子と酸素原子に強制分解し、かつ、通気路の異物を酸化するオゾン強制分解触媒フィルター兼酸化分解フィルターが配置されてなることを特徴としている。   In order to achieve the above object, an air purifying apparatus according to the present invention is provided with an air passage that opens an air suction port at an upstream end and is equipped with exhaust means at a downstream end, and communicates the air suction port with the exhaust means in the body. An ozone generating means is provided on the upstream side of the air passage, and ozone in the air passage is forcibly decomposed into oxygen molecules and oxygen atoms on the downstream side, and foreign matter in the air passage is oxidized. It is characterized in that an ozone forced decomposition catalyst filter and oxidative decomposition filter are arranged.

前記構成の空気清浄装置によれば、空気吸込口より通気路に吸い込まれた空気中の酸素に、オゾン発生手段を作用させるとオゾンが発生する。発生したオゾンは、その直後に、オゾン強制分解触媒フィルター兼酸化分解フィルターの触媒に接触して、酸素分子と酸素原子に強制分解され、酸素分子が排気手段の排気作用により筺体から排出(放出)されると同時に、酸素原子は、その強酸化作用により臭気原因物質、アレルギー原因物質、ウィルス、菌、黴などの通気路内の異物を酸化し、酸化分子として排気手段の排気作用により筺体から排出(放出)される。つまり、排気手段の排気作用により、筺体からは浄化された空気が排出されるものの、オゾンが排出(吐出)されることはない。   According to the air cleaning device having the above configuration, ozone is generated when the ozone generating means is applied to oxygen in the air sucked into the air passage from the air suction port. Immediately after that, the generated ozone contacts the catalyst of the ozone forced decomposition catalyst filter and oxidative decomposition filter and is forcibly decomposed into oxygen molecules and oxygen atoms, and the oxygen molecules are discharged (released) by the exhaust means of the exhaust means. At the same time, oxygen atoms oxidize foreign substances in the ventilation path such as odor-causing substances, allergy-causing substances, viruses, fungi, and soot due to their strong oxidizing action, and are discharged from the enclosure as oxidizing molecules by the exhausting action of the exhaust means. (Released). That is, although the purified air is discharged from the housing by the exhaust action of the exhaust means, ozone is not discharged (discharged).

本発明に係る空気清浄装置のオゾン強制分解触媒フィルター兼酸化分解フィルターは、ハニカム基材またはラジエータフィン基材からなる担体に、触媒を担持したものが望ましい。これによると、ハニカム基材またはラジエータフィン基材からなる担体は、通気路を流下するオゾン含有空気との接触面積が拡大されるので、触媒は、接触面積を拡大した担体に担持されることとなる。そのため、オゾンと触媒との接触が促進されてオゾンの分解効率および酸素原子による通気路内異物の酸化効率を高めることができる。また、オゾン含有空気との接触面積を拡大できるハニカム基材またはラジエータフィン基材からなる担体は、オゾン含有空気の流れを整流して、縮流の発生を抑制できる。その結果、オゾンの分解効率および酸素原子による通気路内異物の酸化効率の向上に寄与することになる。   The ozone forced decomposition catalyst filter / oxidative decomposition filter of the air purifying apparatus according to the present invention is preferably one in which a catalyst is supported on a carrier made of a honeycomb substrate or a radiator fin substrate. According to this, since the support area of the carrier made of the honeycomb base material or the radiator fin base material is expanded in the contact area with the ozone-containing air flowing down the air passage, the catalyst is supported on the support with the expanded contact area. Become. Therefore, the contact between ozone and the catalyst is promoted, and the decomposition efficiency of ozone and the oxidation efficiency of foreign matter in the air passage by oxygen atoms can be increased. Moreover, the support | carrier which consists of a honeycomb base material or a radiator fin base material which can expand a contact area with ozone-containing air can rectify the flow of ozone-containing air, and can suppress generation | occurrence | production of a contracted flow. As a result, it contributes to the improvement of the decomposition efficiency of ozone and the oxidation efficiency of foreign matter in the air passage by oxygen atoms.

本発明に係る空気清浄装置の前記担体は、アルミまたはセラミックス製が望ましい。これによると、担体の生産性および組立性が向上するとともに、経済性を高めて実質的な低コスト化を図れる。   The carrier of the air cleaning device according to the present invention is preferably made of aluminum or ceramics. According to this, the productivity and assembly of the carrier can be improved, and the cost can be substantially reduced by improving the economy.

本発明に係る空気清浄装置の前記触媒は、酸化クロム、酸化ニッケル、酸化コバルト、酸化第二鉄、酸化銅、二酸化マンガン、二酸化ケイ素のうちの少なくとも1つからなればよい。これによると、オゾンの分解効率および酸素原子による通気路内異物の酸化効率を高めることが可能となる。   The catalyst of the air cleaning device according to the present invention may be composed of at least one of chromium oxide, nickel oxide, cobalt oxide, ferric oxide, copper oxide, manganese dioxide, and silicon dioxide. According to this, it becomes possible to improve the decomposition efficiency of ozone and the oxidation efficiency of foreign matter in the air passage by oxygen atoms.

本発明に係る空気清浄装置は、通気路内においてオゾン発生手段により発生したオゾンは、その直後に、オゾン強制分解触媒フィルター兼酸化分解フィルターによって酸素分子と酸素原子に強制分解されるので、排気手段の排気作用による筺体からのオゾン排出(放出)を確実に防止できる。そのため、本発明に係る空気清浄装置が設置される居室内等の換気を図ったり、居室内等のオゾン濃度を確認するなどの煩雑なオゾン管理が不要になる。   In the air purifying apparatus according to the present invention, ozone generated by the ozone generating means in the air passage is immediately decomposed into oxygen molecules and oxygen atoms by the ozone forced decomposition catalyst filter and oxidative decomposition filter. Ozone emission (release) from the housing due to the exhausting action of can be reliably prevented. This eliminates the need for complicated ozone management such as ventilation in a living room or the like in which the air purifying apparatus according to the present invention is installed, or checking the ozone concentration in the living room or the like.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing an embodiment of an air purifying apparatus according to the present invention, in which a part of a front plate is cut away to show the inside, and FIG. 2 is a left side view of FIG. FIG. 3 is a rear view of FIG. 1 showing the inside with a part of the back plate cut out, and FIG. 4 is a plan view of FIG. 3 showing the inside with a part of the top plate cut out.

図1〜図4において、空気清浄装置1は外装体として機能する金属製の筺体2を備える。この筺体2は、正面板2aの上端部を上流端として空気吸込口3を開口し、背面板2bの上端部を下流端として排気ファン4を装備するとともに、その内部は、正面板2aと背面板2bとの間の中間よりも少し背面板2b側に偏った位置において、下端部を開放して天板2cから鉛直にのびる隔壁5で区画された略U字形の通気路6が設けられており、この通気路6の上流側、つまり、通気路6における空気吸込口3の近傍には、紫外線照射ランプからなるオゾン発生手段7が配置されている。なお、オゾン発生手段7は放電管でもよい。   1-4, the air purification apparatus 1 is equipped with the metal housing 2 which functions as an exterior body. The housing 2 is equipped with an exhaust fan 4 with the upper end of the front plate 2a as an upstream end and an air suction port 3 with the upper end of the back plate 2b as a downstream end. At a position slightly deviated toward the back plate 2b side from the middle between the face plate 2b, a substantially U-shaped air passage 6 is provided that is partitioned by a partition wall 5 that opens the lower end portion and extends vertically from the top plate 2c. In addition, ozone generating means 7 including an ultraviolet irradiation lamp is disposed on the upstream side of the ventilation path 6, that is, in the vicinity of the air suction port 3 in the ventilation path 6. The ozone generating means 7 may be a discharge tube.

オゾン発生手段7の下流側には、オゾン強制分解触媒フィルター兼酸化分解フィルター8が、上流位置の第1ユニット8aと、中間位置の第2ユニット8bおよび下流位置の第3ユニット8cの三つに分割して配置される。なお、中間位置の第2ユニット8bおよび下流位置の第3ユニット8cの使用を省略して、上流位置の第1ユニット8aのみでオゾン強制分解触媒フィルター兼酸化分解フィルター8を構成してもよい。   On the downstream side of the ozone generating means 7, an ozone forced decomposition catalytic filter / oxidative decomposition filter 8 is divided into three units: a first unit 8 a at an upstream position, a second unit 8 b at an intermediate position, and a third unit 8 c at a downstream position. It is divided and arranged. Note that it is possible to omit the use of the second unit 8b at the intermediate position and the third unit 8c at the downstream position, and the ozone forced decomposition catalyst filter / oxidative decomposition filter 8 may be configured by only the first unit 8a at the upstream position.

オゾン強制分解触媒フィルター兼酸化分解フィルター8は、オゾン発生手段7で発生した通気路6のオゾン(O)を、酸素分子(O)と酸素原子(O)に強制分解するとともに、強制分解により生じた酸素原子(O)により、通気路6内の臭気原因物質、アレルギー原因物質、ウィルス、菌、黴などの異物と結合してこれらを酸化する。 The ozone forced decomposition catalyst filter / oxidative decomposition filter 8 forcibly decomposes ozone (O 3 ) in the air passage 6 generated by the ozone generating means 7 into oxygen molecules (O 2 ) and oxygen atoms (O) and forcibly decomposes. Oxygen atoms (O) generated by the oxidant combine with foreign substances such as odor-causing substances, allergy-causing substances, viruses, fungi, and sputum in the air passage 6 to oxidize them.

各ユニット8a〜8cに分割されているオゾン強制分解触媒フィルター兼酸化分解フィルター8は、図5(a)に示すように、アルミまたはセラミックス製のハニカム基材からなる担体80に、酸化クロム、酸化ニッケル、酸化コバルト、酸化第二鉄、酸化銅、二酸化マンガン、二酸化ケイ素のうちの少なくとも1つからなる触媒81を担持した構造、または、図5(b)に示すように、アルミまたはセラミックス製のラジエータフィン基材からなる担体82に、前記の触媒81を担持した構造からなる。   As shown in FIG. 5 (a), the ozone forced decomposition catalytic filter / oxidative decomposition filter 8 divided into the units 8a to 8c is provided with a carrier 80 made of an aluminum or ceramic honeycomb substrate, with chromium oxide, A structure in which a catalyst 81 made of at least one of nickel, cobalt oxide, ferric oxide, copper oxide, manganese dioxide, and silicon dioxide is supported, or, as shown in FIG. The catalyst 82 is supported on a carrier 82 made of a radiator fin base.

ハニカム基材からなる担体80およびラジエータフィン基材からなる担体82への触媒81の担持は、触媒81を二酸化ケイ素とナトリウムの化合物からなるバインダーで担体80または担体82に塗布して焼成することによって実現できる。なお、図2において、9はステンレス板材からなる遮光体を示す。   The catalyst 81 is supported on the carrier 80 made of the honeycomb substrate and the carrier 82 made of the radiator fin substrate by applying the catalyst 81 to the carrier 80 or the carrier 82 with a binder made of a compound of silicon dioxide and sodium and firing it. realizable. In FIG. 2, 9 indicates a light shielding body made of a stainless steel plate.

前記構成の空気清浄装置1は、主として居室内に設置して使用する。排気ファン4の駆動により筺体2の空気吸込口3から通気路6に吸い込まれた空気(図2の破線矢印F)に、紫外線照射ランプ7から紫外線を照射することによりオゾンが発生する。このオゾンは、発生直後に、オゾン強制分解触媒フィルター兼酸化分解フィルター8の触媒81に接触して、酸素分子(O)と酸素原子(O)に強制分解される。詳しくは、オゾンは、アルミまたはセラミックス製のハニカム基材からなる担体80またはアルミまたはセラミックス製のラジエータフィン基材からなる担体82に担持されている触媒81に接触して、酸素分子(O)と酸素原子(O)に強制分解される。 The air purifier 1 having the above-described configuration is mainly used in a living room. Ozone is generated by irradiating ultraviolet rays from the ultraviolet irradiation lamp 7 onto the air (broken arrow F in FIG. 2) sucked into the air passage 6 from the air suction port 3 of the housing 2 by driving the exhaust fan 4. Immediately after generation, the ozone comes into contact with the catalyst 81 of the ozone forcible decomposition catalyst filter / oxidative decomposition filter 8 and is forcibly decomposed into oxygen molecules (O 2 ) and oxygen atoms (O). Specifically, ozone comes into contact with the catalyst 81 carried on the carrier 80 made of an aluminum or ceramic honeycomb substrate or the carrier 82 made of an aluminum or ceramic radiator fin substrate, and oxygen molecules (O 2 ). And oxygen atoms (O).

前記強制分解された酸素分子は排気ファン4の排気作用により筺体2から排出され、また、前記強制分解された酸素原子は、その強酸化作用により臭気原因物質、アレルギー原因物質、ウィルス、菌、黴などの通気路6内の異物を酸化し、酸化分子として排気ファン4の排気作用により筺体2から排出される。つまり、排気ファン4の排気作用により、筺体2からは浄化された空気は排出されるものの、オゾンが排出(放出)されることはない。そのため、空気清浄装置1が設置される居室内の換気を図ったり、居室内等のオゾン濃度を確認するなどの煩雑なオゾン管理が不要になる。   The forcedly decomposed oxygen molecules are exhausted from the housing 2 by the exhausting action of the exhaust fan 4, and the forcedly decomposed oxygen atoms are odor-causing substances, allergenic substances, viruses, fungi, soot The foreign matter in the ventilation path 6 is oxidized and discharged from the housing 2 as oxidized molecules by the exhaust action of the exhaust fan 4. That is, although the purified air is discharged from the housing 2 by the exhaust action of the exhaust fan 4, ozone is not discharged (released). This eliminates the need for complicated ozone management such as ventilating the room where the air purifying apparatus 1 is installed and checking the ozone concentration in the room.

オゾン強制分解触媒フィルター兼酸化分解フィルター8を構成する図5(a)のハニカム基材からなる担体80または図5(b)のラジエータフィン基材からなる担体82は、通気路6を流下するオゾン含有空気(図2の破線矢印F)との接触面積が拡大されるので、触媒81は、接触面積を拡大した担体80または担体82に担持されることとなる。そのため、オゾンと触媒81との接触が促進されてオゾンの分解効率および酸素原子による通気路6内異物の酸化効率を高めることができる。また、オゾン含有空気との接触面積を拡大できるハニカム基材またはラジエータフィン基材からなる担体80,82は、オゾン含有空気の流れを整流して、縮流の発生を抑制できる。その結果、オゾンの分解効率および酸素原子による通気路6内異物の酸化効率の向上に寄与することになる。   The carrier 80 made of the honeycomb substrate shown in FIG. 5 (a) or the carrier 82 made of the radiator fin substrate shown in FIG. 5 (b) constituting the ozone forced decomposition catalyst filter / oxidative decomposition filter 8 is the ozone flowing down the air passage 6. Since the contact area with the contained air (broken arrow F in FIG. 2) is enlarged, the catalyst 81 is supported on the carrier 80 or the carrier 82 having an enlarged contact area. Therefore, the contact between ozone and the catalyst 81 is promoted, and the decomposition efficiency of ozone and the oxidation efficiency of foreign matter in the air passage 6 by oxygen atoms can be increased. Further, the carriers 80 and 82 made of a honeycomb substrate or a radiator fin substrate capable of expanding the contact area with the ozone-containing air can rectify the flow of the ozone-containing air and suppress the occurrence of contraction. As a result, it contributes to the improvement of the decomposition efficiency of ozone and the oxidation efficiency of foreign matter in the air passage 6 by oxygen atoms.

また、前記担体80,82がアルミまたはセラミックス製であることにより、担体80,82の生産性および組立性が向上し、経済性を高めて実質的な低コスト化を図れる。   In addition, since the carriers 80 and 82 are made of aluminum or ceramics, the productivity and assemblability of the carriers 80 and 82 are improved, and the cost can be substantially reduced and the cost can be substantially reduced.

さらに、酸化クロム、酸化ニッケル、酸化コバルト、酸化第二鉄、酸化銅、二酸化マンガン、二酸化ケイ素のうちの少なくとも1つからなる触媒81により、オゾンの分解効率および酸素原子による通気路内異物の酸化効率を高めることが可能となる。オゾン強制分解触媒フィルター兼酸化分解フィルター8の経時的な劣化は、担体80または担体82に担持されている触媒81を再度焼成することで再生させることができる。   Further, the catalyst 81 comprising at least one of chromium oxide, nickel oxide, cobalt oxide, ferric oxide, copper oxide, manganese dioxide, and silicon dioxide is used to decompose ozone and oxidize foreign matter in the air passage by oxygen atoms. Efficiency can be increased. The deterioration over time of the ozone forced decomposition catalyst filter / oxidative decomposition filter 8 can be regenerated by firing the catalyst 81 supported on the carrier 80 or the carrier 82 again.
