発明の開示  Disclosure of the invention
[0003] し力しながら、特許文献 1記載のハ-カム状活性炭は、平板形状であり、低圧力損 失であるため、臭気ガスの流れに偏り（ムラ）が発生して高い脱臭効率を望むことが難 しい。また、平板形状のハ-カム状活性炭では、臭気ガスの通過速度が速いと、臭気 ガスはハ-カム状活性炭の微粒子内に充分進入できず、脱臭性能 (効率および寿命 )の向上が望めない。また、臭気とともに粉塵が発生する臭気ガスを処理するために [0003] However, since the Hercam-type activated carbon described in Patent Document 1 has a flat plate shape and low pressure loss, the flow of odor gas is uneven (uneven), resulting in high deodorization efficiency. It is difficult to hope. In addition, with flat plate-shaped hard cam activated carbon, if the odor gas passing speed is high, the odor gas cannot sufficiently enter the fine particles of the hard cam activated carbon, and improvement in deodorization performance (efficiency and life) cannot be expected. . In addition, to treat odor gas that generates dust with odor
、前記脱臭ユニット内で濾過用フィルターを積層して使用する場合、蒸気状物質がフ ィルターに蒸着してフィルターが早期に目詰まりを起こすおそれがある。 When the filtration filters are stacked in the deodorizing unit, vaporous substances may be deposited on the filter and the filter may be clogged early.
[0004] さらに、前記濾過用フィルターとハ-カム状活性炭は独立しているため、別々に交 換、すなわち 2ケ所の交換が必要となる。また、ハ-カム状活性炭の閉塞防止のため に、水性媒体へ接触させる必要があるので、脱臭ユニットが複雑な構造となるとともに 、大型化になるという問題がある。  [0004] Furthermore, since the filter for filtration and the Herkam-like activated carbon are independent, it is necessary to replace them separately, that is, to replace two places. Further, since it is necessary to contact the aqueous medium in order to prevent clogging of the hard cam activated carbon, there is a problem that the deodorizing unit has a complicated structure and becomes large.
[0005] そこで、本発明は、叙上の事情に鑑み、脱臭効率の向上および取り扱いが容易で 、コンパクトィ匕を図ることができる脱臭ユニットを提供することを目的とする。 In view of the above circumstances, the present invention is easy to improve and handle deodorizing efficiency. An object of the present invention is to provide a deodorizing unit capable of achieving compactness.
[0006] 本発明の脱臭ユニットは、臭気ガスに含まれる成分を吸着する複数の吸着剤粒子 を通気性部材で囲んで環状に形成された吸着剤層と、該吸着剤層に同心状に内装 される、複数の貫通孔を有する環状の吸着体と、前記吸着剤層と吸着体とを保持す る支持構造体とを具備してなることを特徴として 、る。 [0006] The deodorizing unit of the present invention includes an adsorbent layer formed in an annular shape by surrounding a plurality of adsorbent particles adsorbing components contained in an odor gas with a gas-permeable member, and concentrically provided in the adsorbent layer. And a support structure for holding the adsorbent layer and the adsorbent. The adsorbent layer and the adsorbent are each provided with an annular adsorbent having a plurality of through holes.
[0007] なお、本明細書において、臭気ガスに含まれる成分とは、臭気ガスの臭気成分以 外に水分や、常温 (30°C以上で固体となる)低融点ガス化物質、たとえば動物性油 脂分、フエノール、榭脂、オイルミストなどを含むものである。また、本明細書において 、吸着剤粒子とは、破砕状または粒子状などの小さな形状をした吸着剤である。 [0007] In the present specification, the components contained in the odor gas include moisture and low-melting-point gasification substances other than the odor components of the odor gas, such as room temperature (which becomes solid at 30 ° C or higher), such as animal substances. It contains oils and fats, phenol, rosin and oil mist. Further, in the present specification, the adsorbent particles are adsorbents having a small shape such as a crushed shape or a particulate shape.
[0008] 本発明によれば、臭気ガスが通過抵抗の高!、、すなわち通過させる臭気ガスの風 量を低下させる吸着剤層を通過中に粉塵を捕捉するので、吸着体の閉塞を防止して 、脱臭効率を向上させることができる。また、通過抵抗の高い吸着剤層が環状である ため、臭気ガスが均一に流入して、吸着体の全体に拡散することにより、脱臭効率を 向上させることができる。さらに、脱臭ユニットが一体構造となるため、取り扱いが容易 で、コンパクトィ匕を図ることができるとともに、交換作業を容易にすることができる。 発明を実施するための最良の形態 [0008] According to the present invention, the odor gas has high passage resistance, that is, dust is captured while passing through the adsorbent layer that reduces the air volume of the odor gas to be passed. Thus, the deodorization efficiency can be improved. Further, since the adsorbent layer having a high passage resistance is annular, the odor gas can flow uniformly and diffuse throughout the adsorbent, thereby improving the deodorization efficiency. Furthermore, since the deodorizing unit has an integral structure, handling is easy, compactness can be achieved, and replacement work can be facilitated. BEST MODE FOR CARRYING OUT THE INVENTION

The activated carbon 3 is not particularly limited. For example, among activated carbon activated carbon and coconut shell activated carbon, it is preferable to use coconut shell activated carbon with high deodorizing efficiency. In addition, the average particle size of the activated carbon 3 is 1 to: LOmm, preferably 1 to 6 mm, such as a crushed shape or a particle shape. Since irregular crushed coal has a higher deodorizing efficiency, it is preferable to use irregular crushed coal.

In the present embodiment, as the adsorbent piece 22, a hard cam-like adsorbent of length 75 mm × width 75 mm × thickness 15 mm is arranged in 8 rows × 3 stages.
[0014] 本実施の形態では、前記吸着体 21における吸着体片 22がハニカム状吸着剤にさ れているが、本発明においては、力かるハ-カム状の吸着剤に限定されるものではな ぐコルゲート状吸着剤、ガラスやセラミックなどのファイバー構造体の吸着剤から適 宜選定することができる。この吸着剤についても、とくに限定されるものではないが、 化学吸着作用または物理吸着作用を有する吸着剤をノヽニカム状などに成形したもの 、またはハニカム状やコルゲート状などに成形された金属や、紙などの担体に、化学 吸着作用または物理吸着作用を有する吸着剤を担持させたものとすることができる。 また、前記化学吸着作用を有する吸着剤としては、マンガン、コバルト、亜鉛、銅など のいずれかを含む酸ィ匕物、水酸化物、複合酸化物、またはその混合物を用いること ができる。また、前記物理吸着作用を有する吸着剤としては、活性炭、ゼォライト、ァ ルミナ、シリカまたはジルコニァなどを用いることができる。  [0014] In the present embodiment, the adsorbent piece 22 in the adsorbent 21 is formed as a honeycomb-shaped adsorbent. However, in the present invention, the adsorbent piece 22 is not limited to a powerful hard cam-shaped adsorbent. Among them, corrugated adsorbents and adsorbents of fiber structures such as glass and ceramics can be appropriately selected. The adsorbent is not particularly limited, but is formed by forming an adsorbent having a chemical adsorption action or a physical adsorption action into a nonicum shape, a metal shaped into a honeycomb shape or a corrugated shape, A carrier such as paper may be loaded with an adsorbent having a chemical adsorption action or a physical adsorption action.

As the adsorbent having the physical adsorption action, activated carbon, zeolite, alumina, silica, zirconia, or the like can be used.
[0015] また、本発明においては、前記吸着体 21として、触媒体を使用することもできる。か かる触媒体としては、ハ-カム状などの板状の担体に白金や、ノラジウムなどの金属 触媒、酸化バナジウムや、酸化モリブデンなどの酸化触媒を担持させるか、またはこ れらの酸化触媒を混合して焼結させ、ハ-カム状などの板状に成形してもよい。かか る場合には、ヒータなどの加熱手段を取り付けるようにしてもよい。また、前記触媒体 力 ハ-カム状などの板状の担体に酸ィ匕チタンなどの光触媒を担持させたものであ る場合には、可視光線および紫外線を放射する蛍光ランプを取り付けるようにしても よい。この吸着体 21を触媒体により作製することによって、オゾン臭や、複合臭など の特定臭気を高効率にて分解することができる。 [0016] 前記支持構造体 31は、前記吸着体 21の複数の吸着剤片 22を保持するための対 称なコ字形状で、一端が後述の蓋 34に固着される保持金具 32、吸着剤層 1と吸着 体 21の端面に設けられる開口付蓋 33と他の端面を閉塞する蓋 34および両蓋 33、 3 4の長手方向に補強用として配設された線材 (棒材)の支柱 35を含んでいる。前記蓋 33、 34は金属または非金属をプレスによる打ち抜き加工により成形されたものまたは 榭脂成形されたものとすることができる。また、前記吸着剤片 22は保持金具 32間に 差し込んで配置されて 、る。 [0015] In the present invention, a catalyst body may be used as the adsorbent 21. As such a catalyst body, a metal carrier such as platinum, noradium, an oxidation catalyst such as vanadium oxide, molybdenum oxide or the like is supported on a plate-like support such as a hermetic shape, or these oxidation catalysts are supported. They may be mixed and sintered, and formed into a plate shape such as a Hercam shape. In such a case, heating means such as a heater may be attached. In addition, in the case where a photocatalyst such as titanium oxide is supported on a plate-like carrier such as a catalyst body having a hard cam shape, a fluorescent lamp that emits visible light and ultraviolet light is attached. Also good. By producing the adsorbent 21 with a catalyst body, it is possible to decompose specific odors such as ozone odor and composite odor with high efficiency. [0016] The support structure 31 is a symmetrical U-shape for holding the plurality of adsorbent pieces 22 of the adsorbent 21, and one end of which is fixed to a lid 34, which will be described later, an adsorbent Opening lid 33 provided on the end face of layer 1 and adsorbent 21, lid 34 closing the other end face, and supports 34 and both lids 33, 3 4 wire rod (bar) support pillars 35 disposed for reinforcement in the longitudinal direction Is included. The lids 33 and 34 may be formed by stamping a metal or non-metal with a press or by a resin molding. The adsorbent piece 22 is inserted between the holding fittings 32 and arranged.
[0017] 本実施の形態では、前記吸着剤層 1が環状（円筒状)の構造であるため、平面形状 のものに比べて臭気ガスとの接触面積が大きくなり、該吸着剤層 1を貫流する臭気ガ スの流速を低速、たとえば 3〜12mZminとしても所要の処理量を確保することがで きる。そして、このように臭気ガスの流速を低速とすることができるため、吸着剤層 1に おける活性炭 3との接触時間も増え、その微粒子内に臭気ガスが充分進入できるた め、脱臭効率を高めるとともに活性炭の寿命も延ばすことができる。  In the present embodiment, since the adsorbent layer 1 has an annular (cylindrical) structure, the contact area with the odor gas is larger than that of the planar shape, and the adsorbent layer 1 flows through the adsorbent layer 1. Even if the flow rate of the odor gas is low, for example, 3 to 12 mZmin, the required throughput can be secured. Since the flow rate of the odor gas can be reduced in this manner, the contact time with the activated carbon 3 in the adsorbent layer 1 is also increased, and the odor gas can sufficiently enter the fine particles, thereby improving the deodorization efficiency. At the same time, the life of activated carbon can be extended.
[0018] また、図 3に示されるように、前記脱臭ユニット Uの周辺に気流 Pの流れが存在する と、該ユニット Uに流入する気流に変流を生じる力 本実施の形態における吸着剤層 1が抵抗体となって、力かる気流の変流を解消し、吸着体 21に流入する気流を均一 にすることができる。したがって、吸着体 21による脱臭作用を有効に発揮させることが できる。また、気流の流れに乗った粉塵のうち、付着性のある粉塵もしくは粒径の大き V、粉塵または臭気ガスに含まれる水分は、吸着剤層 1によって捕集または除去される ため、吸着体 21の閉塞を防止することができる。この吸着剤層 1による閉塞防止効果 によって、吸着体 21を水性媒体に接触させる装置の必要がなくなり、脱臭ユニットを 小型化することができる。  In addition, as shown in FIG. 3, when there is a flow of the air flow P around the deodorizing unit U, the force that causes a change in the air flow flowing into the unit U. The adsorbent layer in the present embodiment 1 becomes a resistor, so that the transformation of the powerful air current can be eliminated, and the air current flowing into the adsorbent 21 can be made uniform. Therefore, the deodorizing action by the adsorbent 21 can be effectively exhibited. Also, among the dust on the airflow, the adhering dust or the large particle size V, the moisture contained in the dust or odorous gas is collected or removed by the adsorbent layer 1, and therefore the adsorbent 21 Can be prevented. Due to the blocking effect by the adsorbent layer 1, there is no need for a device for bringing the adsorbent 21 into contact with an aqueous medium, and the deodorizing unit can be downsized.
[0019] また、前記脱臭ユニット Uは一体構造であるため、メンテナンスのときに交換を比較 的容易に行うことができる。  [0019] Further, since the deodorizing unit U has an integral structure, replacement can be performed relatively easily during maintenance.

It is possible to deodorize the odor gas and to make it cleaner by installing the filter 41 to be installed. The filtration filter 41 is held at both ends by a holding fitting 42 having a pair of annular recesses, and one supporting fitting 42 is fixed to the lid 34. In addition, the other holding metal 42 is provided with a pin 43 for aligning the lid 33 with opening and the support 35.
