Description

本発明は、触媒作用で空気を浄化させる空気洗浄装置に係り、特に、酸化または還元触媒を用いた空気浄化装置に関する。   The present invention relates to an air cleaning device that purifies air by catalytic action, and more particularly to an air purification device that uses an oxidation or reduction catalyst.

一般に、この種の空気浄化装置は、建物の室内や冷蔵庫の庫内や乗物内の空気に含まれている臭気成分や有害成分を分解して脱臭したり、浄化するようになっている。   In general, this type of air purifying apparatus decomposes and deodorizes and purifies odor components and harmful components contained in the air in a building, in a refrigerator, or in a vehicle.

このうち、冷蔵庫に備えられる空気浄化装置は、特許文献１に記載されたように構成され、角筒状のダクト内に形成される流路に脱臭装置として設けられる。この脱臭装置は、流路内にプレフィルタ、放電手段、光触媒モジュールおよびオゾン分解手段を順次配置し、流路に案内される空気に、放電手段による高電圧放電により紫外線やオゾンを発生させ、発生した紫外線を光触媒モジュールにより光触媒作用させ、またオゾンをオゾン分解手段によりオゾン分解作用させて庫内の冷気に含まれている臭気成分や有害成分を酸化分解し、脱臭したり、空気浄化している。   Among these, the air purification device provided in the refrigerator is configured as described in Patent Document 1, and is provided as a deodorizing device in a flow path formed in a rectangular tube-shaped duct. This deodorization device generates pre-filter, discharge means, photocatalyst module and ozone decomposition means in the flow path, and generates ultraviolet rays and ozone in the air guided by the flow path by high voltage discharge by the discharge means. The photocatalyst module is used for photocatalysis by the photocatalyst module, and ozone is decomposed by the ozone decomposing means to oxidize and decompose odorous components and harmful components contained in the cool air in the cabinet to deodorize or purify the air. .

しかし、空気浄化装置は、ダクト内の流路にプレフィルタ、放電手段、光触媒モジュールおよびオゾン分解手段等の多数の装置構成機器をそれぞれ配置した構成のため、ダクト内流路の通風抵抗が大きく通風流量を充分に確保することができない。このため、空気浄化装置は、殺菌や脱臭作用に寄与する流体流量が少なく、充分な空気浄化効果を挙げることが困難であった。   However, the air purification device has a configuration in which a large number of device components such as a prefilter, a discharge means, a photocatalyst module, and an ozone decomposition means are arranged in the flow path in the duct. A sufficient flow rate cannot be secured. For this reason, the air purification device has a small fluid flow rate that contributes to sterilization and deodorization, and it is difficult to obtain a sufficient air purification effect.

また、従来の空気浄化装置は、図２４および図２５に示すように、角筒状ダクト１内に形成される流路２を横断するように、直交方向または斜めに触媒担持体３または４が設置される。触媒担持体３または４は、多孔質構造やハニカム構造に構成され、酸化触媒や還元触媒を担持している。   In addition, as shown in FIGS. 24 and 25, the conventional air purification apparatus has the catalyst carrier 3 or 4 that is orthogonal or oblique so as to cross the flow path 2 formed in the rectangular duct 1. Installed. The catalyst carrier 3 or 4 has a porous structure or a honeycomb structure, and carries an oxidation catalyst or a reduction catalyst.

触媒担持体３または４をダクト１内の流路（通風断面積：Ｓ０）２に直交するように横断設置したり、斜設しているが、横断設置した場合、耐風圧の関係から点線で示す担持体厚みがＴ０と大きくしなければならず、通風抵抗が増大する。触媒担持体３を斜設した場合にも、実線で示す担持体幅がＴ１だけ必要となる。 The catalyst carrier 3 or 4 is installed transversely or obliquely so as to be orthogonal to the flow path (ventilation cross-sectional area: S 0 ) 2 in the duct 1. carrier thickness indicated by the must be increased and T 0, ventilation resistance is increased. Even when the obliquely the catalyst carrier 3, carrier width indicated by the solid line is required only T 1.

触媒担持体３または４に酸化または還元触媒を担持させてダクト１内の流路２の横断面を覆うように断面全域に配置すると、触媒担持体３は体積Ｖ（＝Ｓ０・Ｔ０）となり、通風抵抗はＲ０・Ｒ１の曲線で表わされるように大きい。 When an oxidation or reduction catalyst is supported on the catalyst support 3 or 4 and arranged over the entire cross section so as to cover the transverse cross section of the flow path 2 in the duct 1, the catalyst support 3 has a volume V (= S 0 · T 0 ). Thus, the ventilation resistance is large as represented by the curve of R 0 · R 1 .

触媒担持体３をダクト１内流路２に横断配置した場合には、図２６に示すように、空気浄化装置の通風抵抗は曲線Ｒ０で表わされ、図示しない送風機の送風特性（曲線Ｃ０）との組合せでは、大きな圧力損失Ｐ０が発生し、通風風量はＱ０と少ない。 When the catalyst carrier 3 is disposed transversely to the flow path 2 in the duct 1, the ventilation resistance of the air purifier is represented by a curve R0 as shown in FIG. in combination with 0), a large pressure loss P 0 is generated, ventilation air volume is small, the Q 0.

触媒担持体４をダクト１内の流路２に長手方向に斜めに配置した場合には、通風抵抗は通風抵抗曲線Ｒ１で表わされ、通風流量Ｑ１とやや増加するものの大きく、空気浄化装置により、殺菌や脱臭などの浄化反応に寄与する流体流量（通風量）が少なく、空気浄化効果が小さい。 In the case of arranging the catalyst carrier 4 obliquely in the longitudinal direction in the flow path 2 in the duct 1, the ventilation resistance is represented by the ventilation resistance curve R 1, large although slightly increased ventilation flow rate Q 1, air purification Due to the device, the fluid flow rate (air flow rate) contributing to purification reactions such as sterilization and deodorization is small, and the air purification effect is small.

また、触媒担持体３または４の担持体材料はセラミック、紙などが用いられるために、機械的・物理的強度が弱く、剛性上問題があった。   Further, since the support material of the catalyst support 3 or 4 is made of ceramic, paper, etc., the mechanical / physical strength is weak and there is a problem in rigidity.

さらに、空気浄化装置に用いられるダクト１は、多くの場合、直線的ではなく、途中で曲がったり、流路断面積が変化している。しかも、空気浄化装置１に案内される空気は、一般に塵埃などを含んでおり、触媒担持体３または４に目詰まりが発生し易く、目詰まりが発生すると通風抵抗がより大きくなり、メンテナンスのインターバルが短くなって、メンテナンスコストが割高になる課題があった。
特開２００１−３５５９５８号公報 Furthermore, in many cases, the duct 1 used in the air purification apparatus is not linear, but is bent in the middle or the cross-sectional area of the flow path is changed. In addition, the air guided to the air purification device 1 generally contains dust and the like, and the catalyst carrier 3 or 4 is likely to be clogged. When clogging occurs, the ventilation resistance becomes larger, and the maintenance interval is increased. However, there is a problem that the maintenance cost becomes high.
JP 2001-355958 A

［第１実施形態］
図１および図２は本発明に係る空気浄化装置の第１実施形態をそれぞれ示す図である。この空気浄化装置１０は、建物内や冷蔵庫の庫内に設けられ、酸化触媒または還元触媒の触媒作用を利用して殺菌・脱臭等の空気浄化を行なうものである。 [First Embodiment]
1 and 2 are views respectively showing a first embodiment of an air purification device according to the present invention. The air purification device 10 is provided in a building or a refrigerator, and performs air purification such as sterilization and deodorization using the catalytic action of an oxidation catalyst or a reduction catalyst.

空気浄化装置１０は、建物や車内、冷蔵庫の庫内に配置される角筒状（円筒状でもよい。）のダクト１１を有し、このダクト１１内に空気が案内される流路１２が形成される。ダクト１１内の流路１２には酸化触媒または還元触媒を担持した触媒担持体１３が流路長手方向に沿って設置され、格納される。触媒担持体１３は金属材料、樹脂材料、あるいはセラミック材料、好ましくは弾性材料で形成され、多孔質構造、格子構造、ハニカム構造あるいはメッシュ構造に構成される。   The air purification apparatus 10 includes a duct 11 having a rectangular tube shape (may be cylindrical) disposed in a building, a car, or a refrigerator, and a flow path 12 through which air is guided is formed in the duct 11. Is done. A catalyst carrier 13 carrying an oxidation catalyst or a reduction catalyst is installed and stored in the flow path 12 in the duct 11 along the longitudinal direction of the flow path. The catalyst carrier 13 is formed of a metal material, a resin material, or a ceramic material, preferably an elastic material, and has a porous structure, a lattice structure, a honeycomb structure, or a mesh structure.

触媒担持体１３は、矩形のプレート状に形成され、ダクト１１内の流路１２を担持体上流側領域１５と担持体下流側領域１６とに区画している。触媒担持体１３は、ダクト１３内の横断面を略等分に区分している。   The catalyst carrier 13 is formed in a rectangular plate shape, and divides the flow path 12 in the duct 11 into a carrier upstream region 15 and a carrier downstream region 16. The catalyst carrier 13 divides the transverse section in the duct 13 into substantially equal parts.

触媒担持体１３の両端部に流路１２を部分的に閉塞する上流側および下流側じゃま板１７，１８がそれぞれ堰きとして設けられ、触媒担持体１３の一端側は上流側じゃま板１７を介して流路１２の内周壁に設けられ、その他端側は下流側じゃま板１８を介して流路１２の反対側内周壁に設けられる。触媒担持体１３は、上流側じゃま板１７および下流側じゃま板１８によりダクト１１内流路１２の長手方向に沿って平行に固定され、ダクト１１内に格納される。   Upstream and downstream baffles 17 and 18 that partially block the flow path 12 are provided as dams at both ends of the catalyst carrier 13, respectively, and one end of the catalyst carrier 13 is interposed via the upstream baffle 17. The other end side is provided on the inner peripheral wall of the flow path 12 and the other end side is provided on the inner peripheral wall on the opposite side of the flow path 12 via the downstream baffle plate 18. The catalyst carrier 13 is fixed in parallel along the longitudinal direction of the flow path 12 in the duct 11 by the upstream baffle plate 17 and the downstream baffle plate 18, and is stored in the duct 11.

触媒担持体１３により上流側および下流側じゃま板１７，１８間に形成される担持体上流側領域１５は上流側じゃま板１７の開口を介してダクト１１の上流側流路１２ａに連通され、担持体下流側領域１６は下流側じゃま板１８の開口を介してダクト１１の下流側流路１２ｂに連通される。また、担持体上流側領域１５は担持体下流側領域１６に触媒担持体１３の反応孔（連通孔）を介して連通している。この反応孔に酸化触媒や還元触媒が担持されている。   The carrier upstream region 15 formed between the upstream and downstream baffles 17 and 18 by the catalyst carrier 13 is communicated with the upstream flow path 12a of the duct 11 through the opening of the upstream baffle 17 and carried. The body downstream region 16 communicates with the downstream flow path 12 b of the duct 11 through the opening of the downstream baffle plate 18. Further, the support upstream region 15 communicates with the support downstream region 16 through a reaction hole (communication hole) of the catalyst support 13. An oxidation catalyst or a reduction catalyst is supported in the reaction hole.

空気浄化装置１０のダクト１１は、触媒担持体１３がダクト１１の横断面を略等分に二分するようにダクト断面の略中央に、ダクト長手方向に沿って配置される。触媒担持体１３の厚さをＴ（＜＜Ｔ０）、面積をＳ（＝Ｖ／Ｔ＞＞Ｓ０）とすると、長手方向長さを適宜調整することにより、面積Ｓが非常に大きくなり、この空気浄化装置１０の通風抵抗Ｒは、
［数１］
Ｒ≒Ｒ０・（Ｔ／Ｔ０）・（Ｓ０／Ｓ）２＝Ｒ０・（Ｔ／Ｔ０）３
となり、Ｒ０より充分に小さくなる。 The duct 11 of the air purification device 10 is arranged along the longitudinal direction of the duct at the approximate center of the duct cross section so that the catalyst carrier 13 bisects the transverse cross section of the duct 11 into approximately equal parts. When the thickness of the catalyst carrier 13 is T (<< T 0 ) and the area is S (= V / T >> S 0 ), the area S becomes very large by appropriately adjusting the length in the longitudinal direction. The ventilation resistance R of the air purification device 10 is
[Equation 1]
R≈R 0 · (T / T 0 ) · (S 0 / S) 2 = R 0 · (T / T 0 ) 3
And becomes sufficiently smaller than R0 .

すなわち、空気浄化装置１０の通風抵抗曲線Ｒは、触媒担持体１３の表面積Ｓが非常に大きくなり、図３に示すように構成され、従来の空気浄化装置の通風抵抗曲線Ｒ０・Ｒ１より小さくなり、通風特性がＣ０で表わされる従来と同じ送風機のものでは通風流量Ｑが増加する。 That is, the airflow resistance curve R of the air purification device 10 has a very large surface area S of the catalyst carrier 13 and is configured as shown in FIG. 3, and is based on the airflow resistance curve R 0 · R 1 of the conventional air purification device. decreases, intended ventilation characteristics of the conventional same blower represented by C 0 ventilation flow rate Q is increased.

通風流量Ｑの増加により、空気中に含まれ、触媒に接触・付着または接近した物質は触媒の酸化または還元反応によって分解される。例えば、アンモニア（ＮＨ３）、アセトアルデヒド（ＣＨ３ＣＨＯ）などの分子量の小さな臭気性ガスなどは、流速が数ｍ／ｓｅｃ程度以下の範囲で通風流量が増加すると、分解されるガス量が増加し、空気浄化効果は大きくなる。 By increasing the ventilation flow rate Q, substances contained in the air and contacting, adhering to or approaching the catalyst are decomposed by the oxidation or reduction reaction of the catalyst. For example, a small molecular weight odorous gas such as ammonia (NH 3 ) or acetaldehyde (CH 3 CHO) increases the amount of gas decomposed when the flow rate increases within a flow rate of about several m / sec or less. The air purification effect is increased.

なお、この空気浄化装置１０において、触媒担持体１３を矩形プレート状に形成してダクト長手方向に平行に配設した例を示したが、上流側じゃま板１７および下流側じゃま板１８の堰の高さを小さくして、矩形プレート状の触媒担持体１３を斜めに設けてもよい。この場合にも、触媒担持体１３の表面積が大きくなる分、通風抵抗を小さくすることができる。さらに、触媒担持体１３に捩りを入れ、捩られた触媒担持体１３の両端部を上流側じゃま板１７と下流側じゃま板１８で支持させてもよい。   In this air purification device 10, an example in which the catalyst carrier 13 is formed in a rectangular plate shape and arranged in parallel with the longitudinal direction of the duct is shown. However, the upstream side baffle 17 and the downstream side baffle 18 weir The height may be reduced and the rectangular catalyst support 13 may be provided obliquely. Also in this case, the ventilation resistance can be reduced by the increase in the surface area of the catalyst carrier 13. Further, the catalyst carrier 13 may be twisted, and both ends of the twisted catalyst carrier 13 may be supported by the upstream baffle plate 17 and the downstream baffle plate 18.

［第２実施形態］
図４および図５は、本発明に係る空気浄化装置の第２実施形態を示すものである。 [Second Embodiment]
4 and 5 show a second embodiment of the air purifying apparatus according to the present invention.

この実施形態に示された空気浄化装置１０Ａは、角筒状あるいは円筒状のダクト１１内の流路１２に、酸化触媒あるいは還元触媒を担持した筒状の触媒担持体２０が、ダクト１１の長手方向に沿ってほぼ平行に格納される。触媒担持体２０の両端部に内周フランジを形成する上流側じゃま板２１と閉塞板を形成する下流側じゃま板２２とが設けられ、触媒担持体２０は上流側じゃま板２１を介してダクト１１の内周壁に設けられる。触媒担持体２０は、角筒状あるいは円筒状等の筒状担持体２３を有し、この筒状担持体２３は、金属材料、セラミック材料、あるいは樹脂材料、好ましくは弾性材料で形成され、多孔質構造、格子構造、ハニカム構造あるいはメッシュ構造に構成される。   In the air purifying device 10A shown in this embodiment, a cylindrical catalyst carrier 20 carrying an oxidation catalyst or a reduction catalyst in a flow path 12 in a rectangular or cylindrical duct 11 has a longitudinal direction of the duct 11. Stored approximately parallel along the direction. An upstream baffle plate 21 that forms an inner peripheral flange and a downstream baffle plate 22 that forms a closing plate are provided at both ends of the catalyst carrier 20, and the catalyst carrier 20 is connected to the duct 11 via the upstream baffle plate 21. It is provided on the inner peripheral wall. The catalyst carrier 20 has a cylindrical carrier 23 such as a rectangular tube or a cylinder. The cylindrical carrier 23 is formed of a metal material, a ceramic material, or a resin material, preferably an elastic material, and is porous. It is composed of a quality structure, lattice structure, honeycomb structure or mesh structure.

触媒担持体２０は上流側じゃま板２１に片持梁状に固定され、触媒担持体２０の自由端側に下流側じゃま板２２が端板あるいは閉塞板として設けられる。触媒担持体２０は内部に担持体上流側領域２４を形成し、触媒担持体２０の外周側とダクト内周壁との間で担持体下流側領域２５を形成している。上流側じゃま板２１と下流側じゃま板２２との間は、筒状触媒担持体２０により担持体上流側領域２４と担持体下流側領域２５とに区画される。   The catalyst carrier 20 is fixed to the upstream baffle plate 21 in a cantilever shape, and a downstream baffle plate 22 is provided on the free end side of the catalyst carrier 20 as an end plate or a closing plate. The catalyst carrier 20 forms a carrier upstream region 24 therein, and forms a carrier downstream region 25 between the outer periphery of the catalyst carrier 20 and the inner wall of the duct. A space between the upstream baffle plate 21 and the downstream baffle plate 22 is partitioned by the cylindrical catalyst carrier 20 into a carrier upstream region 24 and a carrier downstream region 25.

担持体上流側領域２４は、担持体下流側領域２５に触媒担持体２０の多数の反応孔（貫通孔、網目孔）を介して連通される一方、担持体上流側領域２４は上流側じゃま板２１の開口（フランジ口）を介してダクト上流側流路１２ａに連通され、担持体下流側領域２５は、下流側じゃま板２２周りの環状開口を介してダクト下流側流路１２ｂに連通される。   The support upstream region 24 communicates with the support downstream region 25 via a number of reaction holes (through holes, mesh holes) of the catalyst support 20, while the support upstream region 24 is an upstream baffle plate. 21 is communicated with the duct upstream flow path 12 a through the opening (flange port) 21, and the carrier downstream region 25 is communicated with the duct downstream flow path 12 b through the annular opening around the downstream baffle plate 22. .

触媒担持体２０は酸化触媒や還元触媒を担持して筒状、好ましくは角筒状（円筒状や楕円筒状であってもよい。）をなし、端板としての下流側じゃま板２２で閉塞される。下流側じゃま板２２は、プレート状の触媒担持体構造に構成してもよい。この場合、端板としての触媒担持体の肉厚は、筒状触媒担持体２０の厚みより大きく形成され、端板としての触媒担持体を通る空気流量が筒状担持体２３を通る空気流量との間で調整される。   The catalyst carrier 20 carries an oxidation catalyst or a reduction catalyst and has a cylindrical shape, preferably a rectangular tube shape (may be cylindrical or elliptical), and is closed by a downstream baffle plate 22 as an end plate. Is done. The downstream baffle plate 22 may be configured in a plate-shaped catalyst support structure. In this case, the thickness of the catalyst carrier as the end plate is formed larger than the thickness of the cylindrical catalyst carrier 20, and the air flow rate through the catalyst carrier as the end plate is the same as the air flow rate through the cylindrical carrier 23. Adjusted between.

触媒担持体２０は、第１実施形態に示された触媒担持体１３と同じ材料で、同じ構造に構成される。   The catalyst carrier 20 is made of the same material and the same structure as the catalyst carrier 13 shown in the first embodiment.

第２実施形態に示された空気浄化装置１０Ａにおいては、触媒担持体２０のダクト長手方向に垂直な面の投影形状を環状とし、触媒担持体２０とダクト内周壁との間に隙間（スリーブ状空間）を設け、筒状触媒担持体２０内に担持体上流側領域２４を、触媒担持体２０の外周側に担持体下流側領域２５をそれぞれ形成する。   In the air purification apparatus 10A shown in the second embodiment, the projected shape of the surface perpendicular to the longitudinal direction of the duct of the catalyst carrier 20 is annular, and a gap (sleeve shape) is formed between the catalyst carrier 20 and the inner peripheral wall of the duct. A support body upstream region 24 is formed in the cylindrical catalyst support 20, and a support downstream region 25 is formed on the outer peripheral side of the catalyst support 20.

そして、筒状触媒担持体２０を上流側じゃま板２１を介してダクト内周壁に固定し、触媒担持体２０を筒状に構成したので、空気流通用表面積、ひいては空気の通過面積を充分に大きくとることができ、通風抵抗Ｒを小さくして空気流量Ｑを増加させることができる。   Since the cylindrical catalyst support 20 is fixed to the inner wall of the duct via the upstream baffle plate 21 and the catalyst support 20 is configured in a cylindrical shape, the air circulation surface area and thus the air passage area is sufficiently large. The airflow resistance R can be reduced and the air flow rate Q can be increased.

この空気浄化装置１０Ａにおいても、空気中に含まれる臭気成分や有害成分を、触媒担持体２０に担持された酸化触媒や還元触媒と積極的に接触させたり、付着または接近させることができ、酸化または還元反応によって分解させ、空気浄化作用を効率よく効果的に行なうことができる。下流側じゃま板２２を触媒担持体で構成した場合には、触媒担持体の接触面積とにより増加させることができるので、空気浄化作用はより一層向上する。   Also in this air purification device 10A, odorous components and harmful components contained in the air can be positively brought into contact with, attached to, or approached to the oxidation catalyst and the reduction catalyst supported on the catalyst carrier 20, and the oxidation Or it can be decomposed | disassembled by a reductive reaction and an air purification effect | action can be performed efficiently and effectively. When the downstream side baffle plate 22 is formed of a catalyst carrier, the air purification effect can be further improved because the downstream baffle plate 22 can be increased depending on the contact area of the catalyst carrier.

なお、図４に示された空気浄化装置１０Ａは、筒状の触媒担持体２３を上流側じゃま板２１を介してダクト内周壁に固定した例を示したが、上流側じゃま板を端板で構成し、下流側じゃま板を内周フランジ状あるいはリング状に形成し、筒状の触媒担持体２３を下流側じゃま板２２によりダクト内周壁に片持梁状に固定し、この触媒担持体２３の自由端側を端板としての上流側じゃま板で閉塞してもよい。   In the air purification apparatus 10A shown in FIG. 4, the cylindrical catalyst carrier 23 is fixed to the inner wall of the duct via the upstream baffle plate 21, but the upstream baffle plate is an end plate. The downstream baffle plate is formed in an inner peripheral flange shape or a ring shape, and the tubular catalyst carrier 23 is fixed to the inner circumferential wall of the duct by the downstream baffle plate 22 in a cantilever shape.

［第３実施形態］
図６および図７は、本発明に係る空気浄化装置の第３実施形態を示すものである。 [Third Embodiment]
6 and 7 show a third embodiment of the air purifying apparatus according to the present invention.

この実施形態に示された空気浄化装置１０Ｂは、酸化触媒または還元触媒を担持した触媒担持体３０の構造に特徴を有し、他の構成および作用は第２実施形態に示された空気浄化装置１０Ａと異ならないので、同じ構成には同一符号を付して説明を省略する。   The air purification apparatus 10B shown in this embodiment has a feature in the structure of the catalyst carrier 30 carrying an oxidation catalyst or a reduction catalyst, and other configurations and operations are the air purification apparatus shown in the second embodiment. Since it is not different from 10A, the same components are denoted by the same reference numerals and description thereof is omitted.

空気浄化装置１０Ｂの触媒担持体３０は、角筒状あるいは円筒状等の筒状担持体２３を有し、この筒状担持体２３内にブリッジ状の仕切担持体プレート３１を筒状担持体２３の長手方向に介装させて一体化し、横断面「日」形状に構成したもので、触媒担持体３０の物理的・機械的強度を向上させたものである。仕切担持体プレート３１は筒状担持体３１内の内部空間を２分するように設けられる。仕切られた内部空間（小空間）は筒状担持体２３の長手方向にかつ平行に延設される。この仕切担持体プレート３１は筒状担持体２３内に斜めに設置してもよい。 The catalyst carrier 30 of the air purification apparatus 10B has a cylindrical carrier 23 such as a rectangular tube or a cylinder, and a bridge-like partition carrier plate 31 is placed in the cylindrical carrier 23. The catalyst support 30 is improved in physical and mechanical strength by being integrated in the longitudinal direction and configured in a “day” cross section. The partition carrier plate 31 is provided so as to divide the internal space in the cylindrical carrier 31 into two. The partitioned internal space (small space) extends in parallel with the longitudinal direction of the cylindrical carrier 23 . The partition carrier plate 31 may be installed obliquely in the cylindrical carrier 23 .

空気浄化装置１０Ｂの触媒担持体３０は、上流側じゃま板１７と下流側じゃま板１８との間で、触媒担持体３０内に内部空間を長手方向に沿って２分された担持体上流側領域２４と触媒担持体３０の外周側かつダクト１１内周壁との間に形成された担持体下流側領域２５とに区画される。   The catalyst carrier 30 of the air purification device 10B is a carrier upstream region in which the internal space is divided into two along the longitudinal direction in the catalyst carrier 30 between the upstream baffle plate 17 and the downstream baffle plate 18. 24 and a support downstream side region 25 formed between the outer periphery of the catalyst support 30 and the inner peripheral wall of the duct 11.

担持体上流側領域２４は筒状の触媒担持体３０の網目状あるいは貫通穴形状の反応孔を介して担持体下流側領域２５に連通される。触媒担持体３０の反応孔には酸化触媒や還元触媒が担持されている。また、担持体上流側領域２４は、内周フランジ状の上流側じゃま板２１の開口（連通口）を介してダクト１１内の上流側流路１２ａに連通され、担持体下流側領域２５は端板としての下流側じゃま板２２の外周側開口を介してダクト１１の下流側流路１２ｂに連通される。   The support upstream region 24 communicates with the support downstream region 25 through a mesh-shaped or through-hole shaped reaction hole of the cylindrical catalyst support 30. An oxidation catalyst or a reduction catalyst is supported in the reaction hole of the catalyst support 30. The carrier upstream region 24 communicates with the upstream flow path 12a in the duct 11 through the opening (communication port) of the upstream baffle plate 21 having an inner peripheral flange shape, and the carrier downstream region 25 is an end. The downstream side baffle plate 22 as a plate communicates with the downstream side flow path 12b of the duct 11 through an outer peripheral side opening.

下流側じゃま板２２は、第２実施形態の空気浄化装置１０Ａで示されたものと同様、プレート状の触媒担持体で構成してもよい。この場合、下流側じゃま板２２を構成する触媒担持体の厚みを筒状触媒担持体３０の筒状担持体２０や仕切担持体プレート３１の厚みより厚くすることが望ましい。   The downstream side baffle plate 22 may be composed of a plate-shaped catalyst carrier, similar to that shown in the air purification device 10A of the second embodiment. In this case, it is preferable that the thickness of the catalyst carrier constituting the downstream side baffle plate 22 is larger than the thickness of the cylindrical carrier 20 or the partition carrier plate 31 of the cylindrical catalyst carrier 30.

図６および図７に示された空気浄化装置１０Ｂは、第２実施形態に示された触媒担持体２０と同様、触媒担持体３０の筒状担持体２３の厚みを薄くすることができ、長手方向長さを大きくとれば、空気の通過面積は充分に大きくとることができ、通過風量が増加する。 The air purification device 10B shown in FIGS. 6 and 7 can reduce the thickness of the cylindrical carrier 23 of the catalyst carrier 30 in the same manner as the catalyst carrier 20 shown in the second embodiment. If the length in the direction is large, the air passage area can be made sufficiently large, and the amount of passing air increases.

その際、触媒担持体３０は担持体上流側領域２４内に仕切プレート３１を一体に備えて梁の効果が生じ、物理的・機械的強度が補強された補強構造に構成される一方、触媒担持体３０の接触面積をより増大させることができ、酸化あるいは還元反応の促進を図ることができる。下流側じゃま板２２を触媒担持体で構成した場合により、酸化あるいは還元反応をより一層促進させることができる。   At that time, the catalyst carrier 30 is integrally provided with a partition plate 31 in the upstream region 24 of the carrier so that a beam effect is generated and a physical / mechanical strength is reinforced. The contact area of the body 30 can be further increased, and the oxidation or reduction reaction can be promoted. When the downstream side baffle plate 22 is formed of a catalyst carrier, the oxidation or reduction reaction can be further promoted.

また、空気浄化装置１０Ｂは、筒状の触媒担持体３０内の空間を担持体上流側領域２４として、触媒担持体３０とダクト内周壁との間を担持体下流側領域２５とした例を示したが、第２実施形態と同様に、筒状の触媒担持体３０内を担持体下流側領域に、触媒担持体３０とダクト内周壁との間を担持体上流側領域にそれぞれ構成してもよい。この場合、上流側じゃま板を端板に、下流側じゃま板が内周フランジ状あるいはリング状に形成され、図６に示された上流側じゃま板２１と下流側じゃま板２２と入れ替えられる。   Further, the air purifying device 10B shows an example in which the space in the cylindrical catalyst carrier 30 is a carrier upstream region 24 and the space between the catalyst carrier 30 and the duct inner peripheral wall is a carrier downstream region 25. However, similarly to the second embodiment, the inside of the cylindrical catalyst carrier 30 may be configured as a downstream region of the carrier, and the space between the catalyst carrier 30 and the duct inner peripheral wall may be configured as the upstream region of the carrier. Good. In this case, the upstream baffle plate is formed as an end plate and the downstream baffle plate is formed in an inner peripheral flange shape or a ring shape, and is replaced with the upstream baffle plate 21 and the downstream baffle plate 22 shown in FIG.

［第４実施形態］
図８および図９は、本発明に係る空気浄化装置の第４実施形態を示すものである。 [Fourth Embodiment]
8 and 9 show a fourth embodiment of the air purification device according to the present invention.

この実施形態に示された空気浄化装置１０Ｃは、酸化触媒または還元触媒を担持した触媒担持体３５の構造に特徴を有し、他の構成および作用は、第２実施形態に示された空気浄化装置１０Ａと異ならないので、同じ構成には同一符号を付して説明を省略する。   The air purification apparatus 10C shown in this embodiment has a feature in the structure of the catalyst carrier 35 carrying an oxidation catalyst or a reduction catalyst, and other configurations and operations are the same as those of the air purification device shown in the second embodiment. Since it is not different from the apparatus 10A, the same components are denoted by the same reference numerals and description thereof is omitted.

空気浄化装置１０Ｃの触媒担持体３５は、角筒状あるいは円筒状等の筒状担持体２３内に横断面十字状の仕切担持体プレート３６を筒状担持体２３の長手方向に介装させて一体化したものである。筒状担持体２３と補強プレートを兼ねた仕切担持体プレート３６とは一体構造に形成され、内部に担持体上流側領域２４が形成される。この担持体上流側領域２４は筒状担持体２３内に仕切担持体プレート３６を介装することにより複数、例えば４つの小領域（小空間）に区画される。筒状担持体２３および仕切担持体プレート３６は、触媒担持体３５で構成される一方、触媒担持体３５の端部を覆う端板としての下流側じゃま板２２もディスク状あるいはプレート状の触媒担持体で構成してもよい。   The catalyst carrier 35 of the air purification device 10C includes a square carrier or a cylindrical carrier 23 having a cross-shaped partition carrier plate 36 interposed in the longitudinal direction of the cylindrical carrier 23. It is an integrated one. The cylindrical carrier 23 and the partition carrier plate 36 also serving as a reinforcing plate are formed in an integral structure, and the carrier upstream region 24 is formed therein. The carrier upstream region 24 is partitioned into a plurality of, for example, four small regions (small spaces) by interposing a partition carrier plate 36 in the cylindrical carrier 23. The cylindrical carrier 23 and the partition carrier plate 36 are composed of a catalyst carrier 35, while the downstream baffle plate 22 serving as an end plate covering the end of the catalyst carrier 35 is also a disc-like or plate-like catalyst carrier. It may be composed of a body.

また、触媒担持体３５の外周側に、ダクト１１の内周壁との間に担持体下流側領域２５が形成され、この担持体下流側領域２５は担持体上流側領域２４に触媒担持体３５の多数の網目状あるいは貫通孔状の反応孔（小孔）を介して連通される。担持体上流側領域２４は、内周フランジとしての上流側じゃま板２１の開口を介してダクト１１の上流側流路１２ａに連通され、担持体下流側領域２５は、下流側じゃま板２２とダクト内周壁との間のトーラス状あるいはリング状開口を介してダクト下流側流路１２ｂに連通される。   Further, a carrier downstream side region 25 is formed on the outer peripheral side of the catalyst carrier 35 between the inner peripheral wall of the duct 11, and this carrier downstream region 25 is formed in the carrier upstream region 24 of the catalyst carrier 35. It communicates through a number of mesh-like or through-hole-like reaction holes (small holes). The carrier upstream region 24 communicates with the upstream flow path 12a of the duct 11 through the opening of the upstream baffle plate 21 serving as an inner peripheral flange, and the carrier downstream region 25 has the downstream baffle plate 22 and the duct. It communicates with the duct downstream flow path 12b through a torus-shaped or ring-shaped opening between the inner peripheral wall.

この触媒担持体３５は筒状担持体２３を介して担持体上流側領域２４と担持体下流側領域２５を連通させたから、触媒を担持した流路面積を大きくとることができ、さらに、筒状担持体２３内に横断面十字状の仕切担持体プレート３６を設けたので、触媒接触面積を増大させることができる。下流側じゃま板２２を触媒担持体で構成した場合には、流路面積をより一層増加させることができる。   Since the catalyst carrier 35 communicates the carrier upstream region 24 and the carrier downstream region 25 via the cylindrical carrier 23, the area of the flow channel carrying the catalyst can be increased, and the cylindrical carrier 35 Since the partition carrier plate 36 having a cross-shaped cross section is provided in the carrier 23, the catalyst contact area can be increased. When the downstream side baffle plate 22 is formed of a catalyst carrier, the flow path area can be further increased.

第４実施形態に示された空気浄化装置１０Ｃは、触媒担持体３５を筒状担持体２３とその内部に設けられる横断面十字状の仕切担持体プレート３６にて一体に構成したので、触媒担持体３５の物理的・機械的強度をより一層向上させることができる一方、強度を向上させ、剛性を高めても異方性を減少させることができる。   In the air purification apparatus 10C shown in the fourth embodiment, the catalyst carrier 35 is integrally formed by the cylindrical carrier 23 and the partition carrier plate 36 having a cross-shaped cross section provided therein, so that the catalyst carrier 35 is integrated. While the physical and mechanical strength of the body 35 can be further improved, anisotropy can be reduced even if the strength is improved and the rigidity is increased.

また、触媒担持体３５は、横断面十字状の仕切担持体プレート３６を内部に備えて筒状担持体２３で構成したので、空気の通過面積を充分大きくとることができ、かつ、空気と接触する触媒担持体の接触表面積も増大させることができるので、空気流量を増加させることができ、酸化または還元反応によって分解される物質（臭気成分や有害成分）を増加させることができる。   In addition, since the catalyst carrier 35 includes the partition carrier plate 36 having a cross-shaped cross section inside and is configured by the cylindrical carrier 23, the air passage area can be sufficiently large and can be in contact with the air. Since the contact surface area of the catalyst carrier to be increased can be increased, the air flow rate can be increased, and substances (odor components and harmful components) decomposed by the oxidation or reduction reaction can be increased.

第４実施形態に示される空気浄化装置１０Ｃにおいても、触媒担持体３５内に担持体上流側領域２４を、触媒担持体３５とダクト内周壁との間にスリーブ状の担持体下流側領域２５をそれぞれ形成した例を示したが、触媒担持体３５内を担持体下流側領域に、触媒担持体３５とダクト内周壁との間をスリーブ状の担持体上流側領域にそれぞれ形成してもよい。この場合にも、上流側じゃま板２１と下流側じゃま板２２は互いに入れ替わり、上流側じゃま板を端板形状に、下流側じゃま板は内周フランジ形状にそれぞれ形成してもよい。   Also in the air purifying device 10C shown in the fourth embodiment, the carrier upstream region 24 is provided in the catalyst carrier 35, and the sleeve-like carrier downstream region 25 is provided between the catalyst carrier 35 and the duct inner peripheral wall. Although the example in which each is formed is shown, the inside of the catalyst carrier 35 may be formed in the downstream region of the carrier, and the space between the catalyst carrier 35 and the inner peripheral wall of the duct may be formed in the upstream region of the sleeve-like carrier. Also in this case, the upstream baffle plate 21 and the downstream baffle plate 22 may be interchanged, and the upstream baffle plate may be formed in an end plate shape, and the downstream baffle plate may be formed in an inner peripheral flange shape.

［第５実施形態］
図１０および図１１は、本発明に係る空気浄化装置の第５実施形態を示すものである。 [Fifth Embodiment]
10 and 11 show a fifth embodiment of the air purification device according to the present invention.

この実施形態に示された空気浄化装置１０Ｄの基本的構造は、図８および図９に示された空気浄化装置１０Ｃと補強構造を除いて異ならないので、同じ構成および作用には同一符号を付して説明を省略する。   The basic structure of the air purifying device 10D shown in this embodiment is the same as that of the air purifying device 10C shown in FIGS. 8 and 9 except for the reinforcing structure. Therefore, the description is omitted.

第５実施形態に示された空気浄化装置１０Ｄは、内周フランジとしての上流側じゃま板２１の中央開口部に補強部材として横断面十字状のクロスバー３８を介装させる一方、このクロスバーの中央部と下流側じゃま板２２の中央部とを補強を兼ねた連結バー（補強マンドレル）３９で連結し、触媒担持体４０を片持梁状にサポートしている。連結バー３９は、クロスバー３８を介して上流側じゃま板２１と下流側じゃま板２２とを連結し、筒状の触媒担持体４０の機械的・物理的強度を向上させ、剛性アップを図っている。   In the air purifying device 10D shown in the fifth embodiment, a crossbar 38 having a cross-shaped cross section is interposed as a reinforcing member in the central opening of the upstream baffle plate 21 serving as an inner peripheral flange. The central portion and the central portion of the downstream baffle plate 22 are connected by a connecting bar (reinforcing mandrel) 39 that also serves as a reinforcement, and the catalyst carrier 40 is supported in a cantilever shape. The connecting bar 39 connects the upstream side baffle plate 21 and the downstream side baffle plate 22 via the cross bar 38, thereby improving the mechanical and physical strength of the cylindrical catalyst carrier 40 and increasing the rigidity. Yes.

触媒担持体４０は、角筒状（あるいは円筒状）の筒状担持体２３内に横断面十字状の仕切担持体プレート３６が介装されて一体化される一方、仕切担持体プレート３６の中心部に高強度の部材として連結バー３９が補強マンドレルとして長手方向に沿って介装され、触媒担持体４０が補強される。   The catalyst carrier 40 is integrated with a square carrier (or cylindrical) cylindrical carrier 23 by interposing a partition carrier plate 36 having a cross-sectional cross shape, while the center of the partition carrier plate 36 is integrated. The connection bar 39 is interposed as a reinforcing mandrel along the longitudinal direction as a high-strength member in the part, and the catalyst carrier 40 is reinforced.

この触媒担持体４０は、筒状担持体２３内に担持体上流側領域２４が形成され、この担持体上流側領域２４は、仕切担持体プレート３６により４つの小領域（小空間）に区画される。担持体上流側領域２４は、上流側じゃま板２１のクロスバー３８により形成される基盤目状（格子状）の開口を介してダクト１１内の上流側流路１２ａに連通される。   This catalyst carrier 40 has a carrier upstream region 24 formed in a cylindrical carrier 23, and this carrier upstream region 24 is divided into four small regions (small spaces) by a partition carrier plate 36. The The carrier upstream region 24 communicates with the upstream flow path 12 a in the duct 11 through a base-like (lattice-like) opening formed by the cross bar 38 of the upstream baffle plate 21.

担持体上流側領域２４は触媒担持体３５の筒状担持体２３を介してスリーブ状の担持体下流側領域２５に連通され、この下流側領域２５は、下流側じゃま板２２の外周側とダクト内周壁とで形成されたトーラス状あるいはリング状開口を介してダクト下流側領域１２ｂに連通している。   The carrier upstream region 24 communicates with the sleeve-like carrier downstream region 25 via the cylindrical carrier 23 of the catalyst carrier 35, and this downstream region 25 is connected to the outer peripheral side of the downstream baffle plate 22 and the duct. It communicates with the duct downstream region 12b through a torus-shaped or ring-shaped opening formed with the inner peripheral wall.

触媒担持体３５は、角筒状（あるいは円筒状）のダクト１１内に固定された内フランジ状の上流側じゃま板２１に片持梁状に取り付けられる。この場合、下流側じゃま板２２が高強度の連結バー３９を介して上流側じゃま板２１のクロスバー３８に連結され、上流側じゃま板２１はダクト１１の内周壁に固定されるので、触媒担持体３５は、支持強度が向上し、大きな剛性力をもって片持梁状に保持される。   The catalyst carrier 35 is attached in a cantilever manner to the upstream baffle plate 21 having an inner flange shape that is fixed in the duct 11 having a rectangular tube shape (or a cylindrical shape). In this case, the downstream baffle plate 22 is connected to the cross bar 38 of the upstream baffle plate 21 via a high-strength connecting bar 39, and the upstream baffle plate 21 is fixed to the inner peripheral wall of the duct 11, so that the catalyst is supported. The body 35 has improved support strength and is held in a cantilever shape with a large rigidity.

また、空気浄化装置１０Ｄを構成する触媒担持体４０は、角筒状の筒状担持体２３と横断面十字状の仕切担持体プレート３６より一体に構成される一方、仕切担持体プレート３６の中心部に軸方向（長手方向）に延設された連結バー３９で強度的に補強される。連結バー３９の両端部は上流側じゃま板２１のクロスバー３８と下流側じゃま板２２に固定され、上流側じゃま板２１を介して筒状ダクト１１の内周壁に固定される。   The catalyst carrier 40 constituting the air purifying device 10D is integrally formed of a rectangular cylindrical cylindrical carrier 23 and a cross-shaped partition carrier plate 36, while the center of the partition carrier plate 36 is formed. This portion is reinforced in strength by a connecting bar 39 extending in the axial direction (longitudinal direction). Both ends of the connecting bar 39 are fixed to the cross bar 38 of the upstream side baffle plate 21 and the downstream side baffle plate 22, and are fixed to the inner peripheral wall of the cylindrical duct 11 via the upstream side baffle plate 21.

この空気浄化装置１０Ｄは、片持梁状の触媒担持体４０を上流側じゃま板２１を介してダクト内周壁に固定され、触媒担持体４０は高強度の連結バー３９により補強されて取り付けられる。しかも、この触媒担持体４０内の担持体上流側領域２４はダクト上流側流路１２ａに上流側じゃま板２１の中央開口部を介して連通され、この担持体上流側領域２４に触媒担持体４０を介して連通される担持体下流側領域２５は、下流側じゃま板２２で形成される環状の開口を介してダクト下流側流路１２ｂに連通される。   In the air purifying device 10D, a cantilever-shaped catalyst carrier 40 is fixed to an inner wall of a duct via an upstream baffle plate 21 and the catalyst carrier 40 is reinforced and attached by a high-strength connecting bar 39. In addition, the carrier upstream region 24 in the catalyst carrier 40 is communicated with the duct upstream channel 12a through the central opening of the upstream baffle plate 21, and the catalyst carrier 40 is connected to the carrier upstream region 24. The carrier downstream side region 25 communicated via is communicated with the duct downstream side flow passage 12b via an annular opening formed by the downstream side baffle plate 22.

担持体上流側領域２４は、触媒担持体４０の筒状担持体２３内に複数、例えば４つの小領域（小空間）に分けて形成され、担持体下流側領域２５は、触媒担持体４０の外周側とダクト内周壁との間に形成されるスリーブ状の領域である。   The support upstream region 24 is formed in the cylindrical support 23 of the catalyst support 40 in a plurality of, for example, four small regions (small spaces), and the support downstream region 25 is formed on the catalyst support 40. This is a sleeve-like region formed between the outer peripheral side and the duct inner peripheral wall.

この空気浄化装置１０Ｄにおいても、触媒担持体４０は筒状担持体２３と横断面十字状の仕切担持体プレート３６にて一体構成し、仕切担持体プレート３６の中心部に連結バー３９を設けたので、触媒担持体４０の物理的・機械的強度をより一層向上させることができ、剛性力の大きな保持構造となる。   Also in this air purifying device 10D, the catalyst carrier 40 is integrally constituted by the cylindrical carrier 23 and the partition carrier plate 36 having a cross-shaped cross section, and a connecting bar 39 is provided at the center of the partition carrier plate 36. Therefore, the physical and mechanical strength of the catalyst carrier 40 can be further improved, and a holding structure having a large rigidity is obtained.

また、触媒担持体４０は、担持体上流側領域２４を筒状担持体２３を介して担持体下流側領域２５に連通させたので、空気の通過面積を充分に大きくとることができ、かつ、筒状担持体２３内に横断面十字状の仕切担持体プレート３６を介装させて一体構成としたので、触媒と空気の接触表面積を増大させることができ、空気流量を増加させて、酸化または還元反応によって分解される物質を増加させることができる。   In addition, since the catalyst carrier 40 communicates the carrier upstream region 24 with the carrier downstream region 25 via the cylindrical carrier 23, the air passage area can be sufficiently large, and Since the partition carrier plate 36 having a cross-shaped cross section is interposed in the cylindrical carrier 23, the contact surface area between the catalyst and the air can be increased, the air flow rate can be increased, and oxidation or Substances decomposed by the reduction reaction can be increased.

この空気浄化装置１０Ｄにおいても、上流側じゃま板を端板形状とし、下流側じゃま板を内周フランジ形状としてクロスバーを連結することにより、触媒担持体４０の内部を担持体下流側領域に、触媒担持体４０とダクト内周壁との間を担持体上流側領域に形成してもよい。   Also in this air purifying device 10D, the upstream baffle plate has an end plate shape, the downstream baffle plate has an inner peripheral flange shape, and the cross bar is connected, so that the inside of the catalyst carrier 40 is in the carrier downstream region, A space between the catalyst carrier 40 and the inner peripheral wall of the duct may be formed in the upstream region of the carrier.

この実施形態に示された空気浄化装置１０Ｅは、筒状のダクト１１Ａが長手方向に沿って少なくとも一面が湾曲成形され、この湾曲部に触媒担持体２０Ａを格納させた例を示す。第２実施形態に示された空気浄化装置１０Ａと同じ構成および作用には同一符号を付して説明を省略する。   The air purification device 10E shown in this embodiment shows an example in which a cylindrical duct 11A is curved at least on one side along the longitudinal direction, and the catalyst carrier 20A is stored in the curved portion. The same configurations and functions as those of the air purification device 10A shown in the second embodiment are denoted by the same reference numerals, and description thereof is omitted.

触媒担持体２０Ａは、可撓性を有する筒状の弾性材４３で構成され、この弾性材４３に酸化触媒あるいは還元触媒が担持される。筒状弾性材４３は酸化触媒あるいは還元触媒を担持して多数の反応孔（貫通小孔あるいは網目状孔）を有する一方、触媒担持体２０Ａの両端部に上流側じゃま板２１および下流側じゃま板２２が設けられる。上流側じゃま板２１は内周フランジ状に形成されて、ダクト１１Ａの内周壁に固定される。   The catalyst carrier 20 </ b> A is composed of a flexible cylindrical elastic material 43, and an oxidation catalyst or a reduction catalyst is supported on the elastic material 43. The cylindrical elastic member 43 carries an oxidation catalyst or a reduction catalyst and has a large number of reaction holes (through small holes or mesh holes), while the upstream baffle plate 21 and the downstream baffle plate are formed at both ends of the catalyst carrier 20A. 22 is provided. The upstream side baffle plate 21 is formed in an inner peripheral flange shape, and is fixed to the inner peripheral wall of the duct 11A.

触媒担持体２０Ａは片持梁状に形成され、自由端側が端板としての下流側じゃま板２２で閉塞される。この下流側じゃま板２２は触媒担持体で構成してもよい。   The catalyst carrier 20A is formed in a cantilever shape, and the free end side is closed by a downstream baffle plate 22 as an end plate. The downstream baffle plate 22 may be formed of a catalyst carrier.

触媒担持体２０Ａは筒状弾性材４３で構成され、湾曲した筒状ダクト１１Ａの湾曲部に沿って湾曲形成されるようにスペーサ４４で保持される。スペーサ４４はバー状をなし、筒状弾性材４３の外周側に複数本、例えば放射状に配設される。図１３には、ダクト１１Ａの内周壁と触媒担持体２０Ａと外周との間に例えば８本のスペーサ４４を介装した例を示す。複数のスペーサ４４を介装させることで、触媒担持体２０Ａを筒状ダクト１１Ａ内の流路に沿わせて長手方向に配設することができる。   The catalyst carrier 20A is composed of a cylindrical elastic material 43, and is held by a spacer 44 so as to be curved along the curved portion of the curved cylindrical duct 11A. The spacer 44 has a bar shape, and a plurality of spacers 44, for example, are arranged radially on the outer peripheral side of the cylindrical elastic member 43. FIG. 13 shows an example in which, for example, eight spacers 44 are interposed between the inner peripheral wall of the duct 11A, the catalyst carrier 20A, and the outer periphery. By interposing a plurality of spacers 44, the catalyst carrier 20A can be disposed in the longitudinal direction along the flow path in the cylindrical duct 11A.

また、触媒担持体２０Ａ内に担持体上流側領域２４が形成され、この担持体上流側領域２４は上流側じゃま板２１の中央開口部を介してダクト１１Ａの上流側流路１２ａに形成される一方、担持体上流側領域２４は触媒担持体２０Ａを介して担持体下流側領域２５に連通される。担持体下流側領域２５はダクト内周壁と触媒担持体２０Ａとの間に形成されるスリーブ状領域であり、担持体下流側領域２５は、下流側じゃま板２２外周側のトーラス状あるいはリング（環）状開口部を介してダクト下流側流路１２ｂに連通される。   A support upstream region 24 is formed in the catalyst support 20A, and this support upstream region 24 is formed in the upstream flow path 12a of the duct 11A through the central opening of the upstream baffle plate 21. On the other hand, the carrier upstream region 24 communicates with the carrier downstream region 25 via the catalyst carrier 20A. The carrier downstream region 25 is a sleeve-like region formed between the inner wall of the duct and the catalyst carrier 20A, and the carrier downstream region 25 is a torus or ring (ring) on the outer peripheral side of the downstream baffle plate 22. ) It communicates with the duct downstream side flow path 12b through the opening.

しかして、筒状のダクト１１Ａ内を案内される空気は、ダクト上流側領域１２ａから上流側じゃま板２１の中央開口部（中央入口部）を経て担持体上流側領域２４に案内される。この担持体上流側領域２４に案内された空気は、触媒担持体２０Ａの反応孔を通って担持体下流側領域２５に導かれ、環状開口部（環状出口）を通ってダクト下流側流路１２ｂに案内される。   Thus, the air guided in the cylindrical duct 11A is guided from the duct upstream region 12a to the carrier upstream region 24 through the central opening (central inlet portion) of the upstream baffle plate 21. The air guided to the carrier upstream region 24 is guided to the carrier downstream region 25 through the reaction hole of the catalyst carrier 20A, and passes through the annular opening (annular outlet) to the duct downstream channel 12b. Be guided to.

空気が触媒担持体２０Ａ内を流通するとき、酸化触媒あるいは還元触媒と接触して触媒反応が生じ、脱臭・殺菌作用を受けて空気浄化される。その際、触媒担持体２０Ａは、筒状構造に形成され、筒状体の少なくとも全周側面が空気浄化領域として構成されるので、触媒担持体２０Ａの長手方向長さを充分にとれば、空気の通過面積を大きくとることができ、空気流路を増加させることができる。これにより、触媒担持体２０Ａの酸化または還元反応によって分解される物質を増加させ、臭気成分や有害成分を有効的に効率よく除去できる。   When air flows through the catalyst carrier 20A, it contacts with an oxidation catalyst or a reduction catalyst to cause a catalytic reaction and undergoes a deodorizing / sterilizing action to purify the air. At that time, the catalyst carrier 20A is formed in a cylindrical structure, and at least the entire circumferential side surface of the cylindrical body is configured as an air purification region. Therefore, if the length of the catalyst carrier 20A in the longitudinal direction is sufficiently long, The passage area can be increased and the number of air flow paths can be increased. Thereby, the substance decomposed | disassembled by oxidation or reduction reaction of the catalyst carrier 20A can be increased, and an odor component and a harmful component can be removed effectively and efficiently.

この空気浄化装置１０Ｅにおいても、触媒担持体２０Ａの内部空間を担持体下流側領域に、触媒担持体２０とダクト内周壁との間を担持体上流側領域に形成してもよい。   Also in the air purification device 10E, the internal space of the catalyst carrier 20A may be formed in the carrier downstream region, and the space between the catalyst carrier 20 and the duct inner peripheral wall may be formed in the carrier upstream region.

［第７実施形態］
図１４および図１５は、本発明に係る空気浄化装置の第７実施形態を示す図である。 [Seventh Embodiment]
14 and 15 are views showing a seventh embodiment of the air purifying device according to the present invention.

この実施形態に示された空気浄化装置１０Ｆは、酸化触媒または還元触媒を担持した筒状の触媒担持体２０の内部にヘリカル状のプレート４６を介装したものである。他の構成および作用は、第２実施形態に示された空気浄化装置１０Ａと異ならないので、同じ構成には同一符号を付して説明を省略する。   The air purifying device 10F shown in this embodiment has a helical plate 46 interposed inside a cylindrical catalyst carrier 20 carrying an oxidation catalyst or a reduction catalyst. Since other configurations and operations are not different from the air purification device 10A shown in the second embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.

ヘリカル状のプレート４６は、触媒担持体２０の角筒状（あるいは円筒状）の筒状体２３の内周壁に設けられ、固定される。ヘリカル状のプレート４６は、外周側が筒状体２３の内周壁に取り付けられる一方、プレート内周側はその外周側より空気流れ方向にシフトし、内部に螺旋スロープ状のヘリカル流路を構成し、このヘリカル流路を担持体上流側領域２４Ａに形成している。この担持体上流側領域２４Ａは、触媒担持体２０に形成された多数の反応孔を介して担持体下流側領域２５に連通される。   The helical plate 46 is provided on and fixed to the inner peripheral wall of the rectangular cylindrical (or cylindrical) cylindrical body 23 of the catalyst carrier 20. The helical plate 46 is attached to the inner peripheral wall of the cylindrical body 23 on the outer peripheral side, while the inner peripheral side of the plate is shifted in the air flow direction from the outer peripheral side to form a helical slope-shaped helical flow path inside. This helical flow path is formed in the carrier upstream region 24A. The carrier upstream region 24A communicates with the carrier downstream region 25 through a number of reaction holes formed in the catalyst carrier 20.

担持体上流側領域２４Ａは、上流側じゃま板２１の中央開口部（中央入口部）を介してダクト上流側流路１２ａに連通され、担持体下流側領域２５は下流側じゃま板２２外周側の環状開口部を介してダクト下流側流路１２ｂに連通される。担持体下流側領域２５は筒状担持体２０とダクト内周壁との間に形成される。   The carrier upstream region 24A communicates with the duct upstream flow path 12a via the central opening (central inlet portion) of the upstream baffle plate 21, and the carrier downstream region 25 is on the outer peripheral side of the downstream baffle plate 22. It communicates with the duct downstream flow path 12b through the annular opening. The carrier downstream region 25 is formed between the cylindrical carrier 20 and the duct inner peripheral wall.

この空気浄化装置１０Ｆは、筒状ダクト１１内で上流側じゃま板２１に片持梁状に設けられた筒状の触媒担持体２０を格納し、この触媒担持体２０は筒状担持体２３内にヘリカル流路を構成し、このヘリカル流路を担持体上流側領域２４に構成する。ヘリカル流路は触媒担持体２０内に案内された空気を螺旋状に、かつヘリカルプレート４６は内周側が下流側内側を向くように傾斜しているのでスロープ状に、撹拌されつつ案内され、筒状の触媒担持体２０の多数の反応孔（網目孔）を通って担持体下流側領域２５に導かれ、続いてダクト下流側流路１２ｂに案内される。   The air purifying device 10F stores a cylindrical catalyst carrier 20 provided in a cantilever shape on the upstream baffle plate 21 in the cylindrical duct 11, and the catalyst carrier 20 is stored in the cylindrical carrier 23. A helical flow path is formed in the carrier upstream side region 24. The helical flow path is guided while being agitated in the form of a slope because the helical flow is inclined such that the air guided into the catalyst carrier 20 is spiral, and the helical plate 46 is inclined so that the inner peripheral side faces the downstream inner side. The catalyst support 20 is guided to the support downstream region 25 through a number of reaction holes (mesh holes) of the catalyst support 20 and then guided to the duct downstream channel 12b.

この空気浄化装置１０Ｆにおいては、ダクト１１内を案内される空気は、触媒担持体２０内に格納されたヘリカルプレート４６により撹拌され、筒状触媒担持体２０内に導かれるので、触媒担持体２０の軸方向長さ（長手方向長さ）を適宜選択することにより、空気の通過面積を充分に大きくとることができ、空気流量を増加させて、触媒担持体２０の酸化または還元反応によって空気浄化を促進させることができる。   In this air purification apparatus 10F, the air guided in the duct 11 is stirred by the helical plate 46 stored in the catalyst carrier 20 and guided into the cylindrical catalyst carrier 20, so that the catalyst carrier 20 By appropriately selecting the axial length (longitudinal length), the air passage area can be made sufficiently large, the air flow rate can be increased, and the air purification can be performed by the oxidation or reduction reaction of the catalyst carrier 20. Can be promoted.

その際、筒状の触媒担持体２０内の担持体上流側領域２４で、ヘリカルプレート４６により空気が撹拌されるので、ヘリカルプレート４６のプレート表面に酸化あるいは還元触媒を担持させることにより、ヘリカルプレート４６を触媒担持体として構成してもよい。ヘリカルプレート４６を担持体とすることにより、担持体上流側領域２４のヘリカル流路に案内される空気（撹拌流体）をプレート表面に接触させ、触媒反応をより積極的に促進させることができる。   At this time, air is agitated by the helical plate 46 in the carrier upstream side region 24 in the cylindrical catalyst carrier 20, so that an oxidation or reduction catalyst is supported on the plate surface of the helical plate 46, whereby the helical plate 46 46 may be configured as a catalyst carrier. By using the helical plate 46 as a carrier, the air (stir fluid) guided to the helical flow path in the upstream region 24 of the carrier can be brought into contact with the plate surface, and the catalytic reaction can be more actively promoted.

また、筒状の触媒担持体２０に格納されたヘリカルプレート４６により、触媒担持体２０が補強される一方、触媒担持体２０に案内された空気は、担持体上流側領域２４をヘリカル流路（螺旋スロープ）に沿って旋回しながら進み、旋回速度成分を持った流れとなるので、触媒担持体２０の厚み方向にではなく、斜めに通過する。これにより、空気は、触媒担持体２０の実際の厚さ（放射方向の肉厚）より厚い接触長さを有し、触媒反応を効率的に行なうことができる。したがって、触媒担持体２０を通過する空気は、担持された酸化あるいは還元触媒と接触したり、付着し、接近し、酸化または還元反応によって分解される物質が増加し、空気浄化効果が効率よく能率的に発揮される。   Further, the catalyst carrier 20 is reinforced by the helical plate 46 stored in the cylindrical catalyst carrier 20, while the air guided to the catalyst carrier 20 passes through the carrier upstream region 24 in the helical flow path ( Since the flow proceeds along the spiral slope) and has a swirl velocity component, it passes through the catalyst carrier 20 not in the thickness direction but obliquely. Thereby, the air has a contact length larger than the actual thickness (the radial thickness) of the catalyst carrier 20, and the catalytic reaction can be performed efficiently. Therefore, the air passing through the catalyst carrier 20 comes into contact with, adheres to, and approaches the supported oxidation or reduction catalyst, and substances that are decomposed by the oxidation or reduction reaction increase, so that the air purification effect is efficiently performed. Is demonstrated.

この空気浄化装置においても、筒状の触媒担持体の内部空間を担持体下流側領域に、触媒担持体をダクト内周壁との間のスリーブ状空間を担持体上流側領域に形成してもよい。   Also in this air purification device, the internal space of the cylindrical catalyst carrier may be formed in the downstream region of the carrier, and the sleeve-like space between the catalyst carrier and the inner peripheral wall of the duct may be formed in the upstream region of the carrier. .

［第８実施形態］
図１６および図１７は、本発明に係る空気浄化装置の第８実施形態を示す図である。 [Eighth Embodiment]
16 and 17 are views showing an eighth embodiment of the air purification device according to the present invention.

この実施形態に示された空気浄化装置１０Ｇは、上流側じゃま板２１の中央開口部（中央入口部）を上流側から覆うように集塵フィルタ４８を着脱可能に設けたものであり、他の構成および作用は第２実施形態に示された空気浄化装置１０Ａと異ならないので同じ構成には同一符号を付して説明を省略する。   The air purifying device 10G shown in this embodiment is provided with a dust collection filter 48 in a detachable manner so as to cover the central opening (central inlet portion) of the upstream baffle plate 21 from the upstream side. Since the configuration and operation are not different from the air purifying apparatus 10A shown in the second embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.

図１６に示された空気浄化装置１０Ｇは、上流側じゃま板２１の中央開口部を覆うプレート状の集塵フィルタ４８を設け、この集塵フィルタ４８で空気中に浮遊する塵埃などを除去し、筒状の触媒担持体２０の目詰まりを防止している。   The air purification device 10G shown in FIG. 16 is provided with a plate-like dust collection filter 48 that covers the central opening of the upstream baffle plate 21, and the dust collection filter 48 removes dust floating in the air. Clogging of the cylindrical catalyst carrier 20 is prevented.

筒状の触媒担持体２０の流入側を集塵フィルタ４８で覆うことで、このフィルタ作用で空気中の塵埃を除去し、清浄化された空気を担持体上流側領域２４に案内している。したがって、触媒担持体２０の目詰りを有効的にかつ効率よく防止でき、触媒担持体２０による触媒反応を長期に亘り、効率よく発揮することができる。したがって、触媒担持体２０は、長期に亘り空気浄化効果を保つことができる。   By covering the inflow side of the cylindrical catalyst carrier 20 with a dust collecting filter 48, dust in the air is removed by this filter action, and the purified air is guided to the upstream region 24 of the carrier. Therefore, clogging of the catalyst carrier 20 can be effectively and efficiently prevented, and the catalytic reaction by the catalyst carrier 20 can be efficiently exhibited over a long period of time. Therefore, the catalyst carrier 20 can maintain the air purification effect for a long time.

第８実施形態に示された空気浄化装置１０Ｇも、筒状の触媒担持体内を担持体下流側領域に、触媒担持体とダクト内周壁との間のスリーブ状空間を担持体上流側領域にそれぞれ形成してもよい。この場合、担持体上流側領域は上流側環状開口が集塵フィルタで覆設される。   The air purifying apparatus 10G shown in the eighth embodiment also has a cylindrical catalyst carrier in the downstream region of the carrier, and a sleeve-like space between the catalyst carrier and the inner peripheral wall of the duct in the upstream region of the carrier. It may be formed. In this case, the upstream side annular opening of the carrier upstream side region is covered with the dust collecting filter.

［変形例］
図１８および図１９は、本発明に係る空気浄化装置の第８実施形態における変形例を示すものである。 [Modification]
18 and 19 show a modification of the eighth embodiment of the air purifying device according to the present invention.

この変形例に示された空気浄化装置１０Ｈは、上流側じゃま板２１の中央開口部を覆う集塵フィルタ４８Ａのフィルタ構造を改良し、フィルタ面積を増加させたものである。他の構成および作用は、第８実施形態に示された空気浄化装置１０Ｇと異ならないので、同じ構成には同一符号を付して説明を省略する。   The air purification device 10H shown in this modification is obtained by improving the filter structure of the dust collection filter 48A that covers the central opening of the upstream baffle plate 21 and increasing the filter area. Since other configurations and operations are not different from the air purifying device 10G shown in the eighth embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.

図１８に示された空気浄化装置１０Ｈは、筒状ダクト１１内の上流側じゃま板２１にキャップ状の集塵フィルタ４８Ａを設けたものである。集塵フィルタ４８Ａは上流側じゃま板２１の中央開口部（中央入口部）を上流側から覆設したものである。集塵フィルタ４８Ａをキャップ状とすることで、フィルタ面積を増大させることができ、集塵フィルタ４８Ａ自体の目詰まりを有効的に防止できる一方、この集塵フィルタ４８Ａで塵芥等の異物が除去され、清浄な空気が担持体上流側領域２４に案内される。したがって、担持体上流側領域２４から触媒担持体２０を通って担持体下流側領域２５に導かれる空気による触媒担持体２０の目詰まりが効率よく有効的に防止され、集塵フィルタ４８Ａの交換インターバルを長期化することができる。   The air purification device 10H shown in FIG. 18 is provided with a cap-shaped dust collecting filter 48A on the upstream baffle plate 21 in the cylindrical duct 11. The dust collection filter 48 </ b> A is obtained by covering the central opening (central inlet portion) of the upstream baffle plate 21 from the upstream side. By making the dust collection filter 48A into a cap shape, the filter area can be increased and clogging of the dust collection filter 48A itself can be effectively prevented, while foreign matters such as dust are removed by the dust collection filter 48A. Clean air is guided to the carrier upstream region 24. Therefore, clogging of the catalyst carrier 20 by the air guided from the carrier upstream region 24 through the catalyst carrier 20 to the carrier downstream region 25 is effectively and effectively prevented, and the exchange interval of the dust collection filter 48A is prevented. Can be prolonged.

変形例に示された空気浄化装置１０Ｈは、上流側じゃま板２１に集塵フィルタ４８Ａを装着し、この集塵フィルタ４８Ａを上流側に向って凸形をなすキャップ状に形成したので、集塵フィルタ４８Ａのフィルタ面積が大きくなり、集塵フィルタ４８Ａを通る空気通過流速が小さくなり、通風抵抗を小さくするとともに、集塵フィルタ４８Ａの目詰まりがしにくくなる。   In the air purification apparatus 10H shown in the modified example, the dust collection filter 48A is attached to the upstream baffle plate 21, and the dust collection filter 48A is formed in a cap shape that is convex toward the upstream side. The filter area of the filter 48A is increased, the air passage flow velocity through the dust collection filter 48A is reduced, the ventilation resistance is reduced, and the dust collection filter 48A is not easily clogged.

なお、集塵フィルタ４８Ａはキャップ状とした例を示したが、上流側に向って凸形状であれば、種々のフィルタ形状が考えられる。   In addition, although the dust collection filter 48A showed the example made into the cap shape, if it is convex shape toward the upstream, various filter shapes can be considered.

［第９実施形態］
図２０および図２１は、本発明に係る空気浄化装置の第９実施形態を示すものである。 [Ninth Embodiment]
20 and 21 show a ninth embodiment of the air purification device according to the present invention.

この実施形態に示された空気浄化装置１０Ｉは、筒状ダクト１１内に格納される触媒担持体２０Ｂを多重筒構造の筒状担持体で構成し、この触媒担持体２０Ｂを下流側じゃま板５０で片持梁状に支持したものである。第２実施形態に示された空気浄化装置１０Ａと同じ構成には同一符号を付して説明を省略する。   In the air purifying device 10I shown in this embodiment, the catalyst carrier 20B housed in the cylindrical duct 11 is constituted by a cylindrical carrier having a multi-cylinder structure, and the catalyst carrier 20B is arranged on the downstream side baffle plate 50. It is supported like a cantilever. The same components as those of the air purification device 10A shown in the second embodiment are denoted by the same reference numerals, and description thereof is omitted.

下流側じゃま板５０は内周フランジ状をなし、筒状ダクト１１内の内周壁に取り付けられて固定される一方、この下流側じゃま板５０の上流側に多重の筒状構造の触媒担持体５１が上流側に延設されて片持梁状に取り付けられる。   The downstream side baffle plate 50 has an inner peripheral flange shape, and is attached to and fixed to the inner peripheral wall of the cylindrical duct 11. On the upstream side of the downstream side baffle plate 50, a catalyst carrier 51 having a multiple cylindrical structure is provided. Is extended upstream and attached in a cantilevered manner.

触媒担持体５１は、担持体外筒５２とこの外筒５２内に格納される担持体内筒５３とを有する多重筒構造で形成され、この担持体内筒５３および担持体外筒５２の上流側は、端板としてのリング状あるいは環状の上流側じゃま板５４で閉塞される。担持体内筒５３の下流側は閉塞板５５で閉塞される。この閉塞板５５は、ディスク状端板として形成され、下流側じゃま板５０に複数のブリッジを介して一体に構成し、下流側じゃま板５０の一部を構成してもよい。また、閉塞板５０は円周フランジ状の下流側じゃま板５０から独立した構成としてもよい。この場合、担持体内筒５２は環状の上流側じゃま板５４に片持梁状に支持されて担持体外筒５２内に格納される。   The catalyst carrier 51 is formed in a multi-cylinder structure having a carrier outer cylinder 52 and a carrier inner cylinder 53 housed in the outer cylinder 52, and the upstream side of the carrier inner cylinder 53 and the carrier outer cylinder 52 is endless. It is closed by a ring-shaped or annular upstream baffle plate 54 as a plate. The downstream side of the carrying body cylinder 53 is closed by a closing plate 55. The closing plate 55 may be formed as a disk-shaped end plate, and may be configured integrally with the downstream baffle plate 50 via a plurality of bridges, and may constitute a part of the downstream baffle plate 50. Further, the closing plate 50 may be configured independently of the circumferential baffle downstream side baffle plate 50. In this case, the carrier inner cylinder 52 is supported by the annular upstream baffle plate 54 in a cantilever shape and stored in the carrier outer cylinder 52.

しかして、筒状ダクト１１の内周壁と担持体外筒５２との間および担持体内筒５３内に、上流側じゃま板５４と下流側じゃま板５０との間で、担持体上流側領域５６が形成され、担持体外筒５２と担持体内筒５３との間に担持体下流側領域５７が形成される。担持体下流側領域５７はスリーブ状の流路を構成している。   Thus, a carrier upstream region 56 is formed between the inner peripheral wall of the cylindrical duct 11 and the carrier outer cylinder 52 and in the carrier inner cylinder 53 between the upstream baffle plate 54 and the downstream baffle plate 50. Thus, a carrier downstream side region 57 is formed between the carrier outer cylinder 52 and the carrier inner cylinder 53. The carrier downstream region 57 constitutes a sleeve-like flow path.

また、担持体上流側領域５６は、筒状ダクト１１と担持体外筒５２との間に形成されたスリーブ状の筒状流路５８と担持体内筒５３内に形成される中央流路５９とから中心軸を共有する構造に形成される。担持体上流側領域５６は上流側じゃま板５４により形成される開口部（入口部）を介してダクト内上流側流路１２ａに連通される。上流側じゃま板５４に形成される開口部は、ダクト内周壁とリング状の上流側じゃま板５４に形成される環状開口部と上流側じゃま板５４内に形成される中央開口部とにより形成される。   The carrier upstream region 56 includes a sleeve-like cylindrical channel 58 formed between the cylindrical duct 11 and the carrier outer cylinder 52 and a central channel 59 formed in the carrier cylinder 53. It is formed in a structure sharing a central axis. The carrier upstream region 56 communicates with the upstream duct 12a in the duct via an opening (inlet portion) formed by the upstream baffle plate 54. The opening formed in the upstream side baffle 54 is formed by a duct inner peripheral wall, an annular opening formed in the ring-shaped upstream side baffle 54 and a central opening formed in the upstream side baffle 54. The

また、担持体上流側領域５６（５８，５９）は、触媒担持体５１の担持体外筒５２および担持体内筒５３を介して環状あるいはスリーブ状の担持体下流側領域５７に連通され、この担持体下流側領域５６は、下流側じゃま板５０内の開口部を介してダクト内下流側流路１２ｂに連通される。   Further, the carrier upstream region 56 (58, 59) communicates with the annular or sleeve-like carrier downstream region 57 via the carrier outer cylinder 52 and the carrier cylinder 53 of the catalyst carrier 51, and this carrier. The downstream region 56 is communicated with the in-duct downstream flow path 12b through the opening in the downstream baffle plate 50.

この空気浄化装置１０Ｉは、触媒担持体５１が環状あるいはスリーブ状の担持体外筒５２および担持体内筒５３により多重筒構造に構成されているので、触媒担持体５１を通過する空気の通過面積を大幅に増大させることができ、空気は触媒担持体５１の厚い層を通過したものと等価となる。したがって、触媒担持体５１に担持された酸化あるいは還元触媒と接触し、付着し、または接近する空気量が増大し、酸化または還元反応によって分解される物質が増大し、大きな空気浄化効果が得られる。   In this air purifying device 10I, since the catalyst carrier 51 is formed in a multiple cylinder structure by the annular or sleeve-like carrier outer cylinder 52 and the carrier inner cylinder 53, the passage area of the air passing through the catalyst carrier 51 is greatly increased. The air is equivalent to that passed through the thick layer of the catalyst carrier 51. Therefore, the amount of air that comes into contact with, adheres to, or approaches the oxidation or reduction catalyst carried on the catalyst carrier 51 increases, the amount of substances decomposed by the oxidation or reduction reaction increases, and a large air purification effect is obtained. .

第９実施形態に示された空気浄化装置１０Ｉは、筒状ダクト１１のダクト上流側流路１２ａを案内される空気流は、上流側じゃま板５４により分流されて触媒担持体５１の担持体上流側領域５６に導かれる。その際、担持体上流側領域５６にダクト上流側流路１２ａを通る空気流がスムーズに案内されるように、上流側に突出するガイドメンバを設けてもよい。   In the air purifying apparatus 10I shown in the ninth embodiment, the air flow guided through the duct upstream flow path 12a of the cylindrical duct 11 is divided by the upstream baffle plate 54 and upstream of the support of the catalyst support 51. Guided to the side region 56. At this time, a guide member protruding upstream may be provided so that the air flow passing through the duct upstream flow path 12a is smoothly guided to the carrier upstream region 56.

担持体上流側領域５６では、空気流は、環状の筒状流路５８と中央流路５９とに分流され、筒状流路５８に案内された空気流は担持体外筒５２を通って担持体下流側領域５７に、また、中央流路５９に案内された空気流は担持体内筒５３を通って担持体下流側領域５７にそれぞれ導かれる。このため、触媒担持体５１の空気通過面積を大幅に増大させることができ、通風抵抗を減少させることができる他、空気流が触媒に接触し、付着し、または接近して酸化または還元処理される。この触媒反応によって分解される物質が増加し、大きな空気浄化効果が得られる。   In the carrier upstream region 56, the air flow is divided into an annular cylindrical channel 58 and a central channel 59, and the air flow guided to the cylindrical channel 58 passes through the carrier outer cylinder 52 and the carrier. The air flow guided to the downstream region 57 and the central flow path 59 is guided to the carrier downstream region 57 through the carrier cylinder 53. For this reason, the air passage area of the catalyst carrier 51 can be greatly increased, the ventilation resistance can be reduced, and the air flow contacts with, adheres to, or approaches the catalyst to be oxidized or reduced. The Substances decomposed by this catalytic reaction increase, and a large air purification effect can be obtained.

なお、第９実施形態に示された空気浄化装置１０Ｉにおいて、触媒担持体の空気通過面積をより一層増大させるために、下流側じゃま板５０や閉塞板５５を触媒担持体５１と同様な触媒担持体で構成してもよい。この場合、下流側じゃま板５０や閉塞板５５の触媒担持体は筒状触媒担持体５１の肉厚より厚肉に形成される。   In the air purification device 10I shown in the ninth embodiment, the downstream baffle plate 50 and the closing plate 55 are made to have the same catalyst support as the catalyst support 51 in order to further increase the air passage area of the catalyst support. It may be composed of a body. In this case, the catalyst carriers of the downstream baffle plate 50 and the blocking plate 55 are formed thicker than the cylindrical catalyst carrier 51.

この空気浄化装置１０Ｉでは、触媒担持体５１とダクト内周壁との間のスリーブ状空間および担持体内筒５３内の空間を担持体上流側領域５６に、担持体内筒５３とその外筒５２とのスリーブ状空間を担持体下流側領域５７にそれぞれ形成した例を示したが、担持体上流側領域５５と担持体下流側領域５７は逆であってもよい。   In this air purifying device 10I, the sleeve-like space between the catalyst carrier 51 and the inner peripheral wall of the duct and the space in the carrier cylinder 53 are formed in the carrier upstream region 56, and the carrier cylinder 53 and the outer cylinder 52 are separated from each other. Although the example in which the sleeve-like space is formed in the carrier downstream region 57 is shown, the carrier upstream region 55 and the carrier downstream region 57 may be reversed.

すなわち、担持体内筒５３と外筒５２との間のスリーブ状空間を担持体上流側領域に形成し、残りを担持体下流側領域に形成してもよい。   That is, the sleeve-like space between the carrier inner cylinder 53 and the outer cylinder 52 may be formed in the carrier upstream region, and the rest may be formed in the carrier downstream region.

［第１０実施形態］
図２２および図２３は、本発明に係る空気浄化装置の第１０実施形態を示すものである。 [Tenth embodiment]
22 and 23 show a tenth embodiment of an air purification device according to the present invention.

この実施形態に示された空気浄化装置１０Ｊは、筒状ダクト１１内に設けられたディスク状の上流側じゃま板６０に柱状の触媒担持体６１が片持梁状に、ダクト１１の長手方向に延設されるように格納される。触媒担持体６１は角柱状あるいは円柱状の柱体６２を有し、この柱体６２に軸方向（長手方向）に貫通する多数の貫通孔が形成される。貫通孔の一部、例えば大径の貫通孔は上流側じゃま板６０で閉塞され、残りの貫通孔はディスク状端板としての下流側じゃま板６５で閉塞される。   In the air purifying device 10J shown in this embodiment, a columnar catalyst support 61 is formed in a cantilever shape on a disc-shaped upstream baffle plate 60 provided in a cylindrical duct 11 in the longitudinal direction of the duct 11. Stored to extend. The catalyst carrier 61 has a prismatic or cylindrical columnar body 62, and a number of through holes penetrating in the axial direction (longitudinal direction) are formed in the columnar body 62. A part of the through-hole, for example, a large-diameter through-hole, is closed with an upstream baffle plate 60, and the remaining through-holes are closed with a downstream baffle plate 65 as a disk-like end plate.

下流側じゃま板６５で閉塞される多数の貫通孔により、上流側じゃま板６０と下流側じゃま板６５の間に、担持体上流側領域６６が形成される。この担持体上流側領域６６は触媒担持体６１を介して担持体下流側領域６７に連通される。担持体下流側領域６７は、筒状ダクト内周壁と触媒担持体６１との間に形成されるスリーブ状あるいは環状のスリーブ領域６８と、触媒担持体６１の貫通孔により形成される孔状領域６９とから構成される。   A carrier upstream region 66 is formed between the upstream baffle plate 60 and the downstream baffle plate 65 by a large number of through holes blocked by the downstream baffle plate 65. The carrier upstream region 66 communicates with the carrier downstream region 67 through the catalyst carrier 61. The support downstream side region 67 is a hole-like region 69 formed by a sleeve-like or annular sleeve region 68 formed between the inner peripheral wall of the cylindrical duct and the catalyst support 61 and a through hole of the catalyst support 61. It consists of.

担持体上流側領域６６は、上流側じゃま板６０の開口である多数の連通孔を介してダクト上流側流路１２ａに連通され、担持体下流側領域６７は、下流側じゃま板６５のか環状開口および連通孔を介してダクト下流側流路１２ｂに連通される。   The carrier upstream region 66 communicates with the duct upstream flow path 12a through a number of communication holes, which are openings of the upstream baffle plate 60, and the carrier downstream region 67 has an annular opening of the downstream baffle plate 65. And it communicates with the duct downstream flow path 12b through the communication hole.

第１０実施形態の空気浄化装置１０Ｊにおいても、担持体上流側領域６６から触媒担持体６１を通して担持体下流側領域６７に至る通風面積を増大させることができ、担持体上流側領域６６に導かれた空気は大きな通風面積をもって担持体下流側領域６７に案内される。このため、触媒担持体６１の空気通過面積を大幅に増大させることができ、空気流が触媒に接触し、付着し、または接近して酸化または還元処理される。したがって、この触媒反応によって分解される物質が増加し、大きな空気浄化効果が得られる。   Also in the air purification device 10J of the tenth embodiment, the ventilation area from the support upstream region 66 to the support downstream region 67 through the catalyst support 61 can be increased, and is led to the support upstream region 66. The air is guided to the carrier downstream area 67 with a large ventilation area. For this reason, the air passage area of the catalyst carrier 61 can be greatly increased, and the air flow comes into contact with, adheres to, or approaches the catalyst, and is oxidized or reduced. Therefore, the substance decomposed by this catalytic reaction increases, and a large air purification effect is obtained.

この空気浄化装置１０Ｊは、濾過式集塵機に似た構成となるが、濾過式集塵機とは異なり、触媒担持体６１の目を粗く、触媒担持体６１の担持体上流側領域６６と担持体下流側領域６７の厚みを薄くし、長手方向長さを適宜大きくとると、第２実施形態に示された空気浄化装置１０Ａの触媒担持体２０より通風抵抗を小さくとることができる。触媒担持体６１の通風抵抗を小さく、通風量を増大させると、酸化または還元反応によって分解される物質が増加し、大きな空気浄化効果が得られる。   This air purifying device 10J has a configuration similar to a filtration type dust collector, but unlike the filtration type dust collector, the catalyst carrier 61 has rough eyes, the carrier upstream side region 66 of the catalyst carrier 61 and the carrier downstream side. When the thickness of the region 67 is reduced and the length in the longitudinal direction is appropriately increased, the ventilation resistance can be made smaller than that of the catalyst carrier 20 of the air purification device 10A shown in the second embodiment. When the ventilation resistance of the catalyst support 61 is reduced and the ventilation rate is increased, the substance decomposed by the oxidation or reduction reaction increases, and a large air purification effect is obtained.
