Description
本発明は、空気浄化用土壌およびこの空気浄化用土壌を用いた屋内用緑化兼空気浄化装置に係る。詳しくは活性炭と特定の植物と（必要に応じてゼオライト）を併用することによって相乗効果を発現させ、それぞれを単独で使用した場合以上の空気浄化効果（特に、タバコ臭に対する脱臭・消臭効果）を奏することができる空気浄化用土壌およびこの空気浄化用土壌を用いた屋内用緑化兼空気浄化装置に関するものである。 The present invention relates to an air purification soil and an indoor greening and air purification apparatus using the air purification soil. In detail, synergistic effects are expressed by using activated carbon and specific plants in combination (zeolite if necessary), and the air purification effect (especially deodorizing / deodorizing effect against tobacco odor) is higher than when each is used alone. The present invention relates to a soil for air purification that can achieve the above and an indoor greening and air purification device that uses the soil for air purification.
従来から、室内の空気浄化やタバコ臭、ペット臭、トイレ臭、生ごみ臭などの悪臭（いわゆる生活臭）の浄化を行う装置は各種の装置が開発されており、本願出願人も各種の装置を開発している（特許文献１〜３参照）。 Conventionally, various devices have been developed for purifying indoor air and purifying bad odors (so-called living odors) such as cigarette odor, pet odor, toilet odor, garbage odor, etc. (See Patent Documents 1 to 3).
しかし、係る装置はいずれもダクト、ファン、外周壁（フレーム）などの機械的構造を工夫することによって、装置本体が壁面に対して大きく突出しないようにしたり（特許文献１の段落［０００５］）、単位面積当たりの浄化効率の向上を図ったり（特許文献２の段落［０００５］）、外部に送風機の設置スペースを確保する必要をなくしたり（特許文献３の段落［０００５］）することを目的とするものであり、使用する土壌そのものを対象としたものではない。 However, all of these devices are designed so that the device main body does not protrude greatly from the wall surface by devising a mechanical structure such as a duct, a fan, and an outer peripheral wall (frame) (paragraph [0005] of Patent Document 1). The purpose is to improve the purification efficiency per unit area (paragraph [0005] of Patent Document 2), or to eliminate the need to secure an installation space for the blower outside (paragraph [0005] of Patent Document 3). It is not intended for the soil itself.
一方、臭気の浄化を目的とした土壌としては、例えば特許文献４、５に記載の脱臭用土壌などがある。また、特許文献６には特定の植物精油と水系樹脂を用いることによって粉塵の発生を防止するとともに臭気の抑制を図ることを目的とする土砂処理剤が開示されている。 On the other hand, as the soil for the purpose of odor purification, there are deodorizing soils described in Patent Documents 4 and 5, for example. Patent Document 6 discloses a soil treatment agent for the purpose of preventing generation of dust and suppressing odor by using a specific plant essential oil and an aqueous resin.
しかしながら、特許文献４、５に記載の土壌は、食品残さや畜産廃棄物などから出るアンモニアや各種の硫化物の臭気を対象とするものであり、タバコ臭（特に、ニコチンや窒素酸化物などの窒素化合物、アセトアルデヒド、アンモニア、酢酸などの臭気）やペット臭などの生活臭を対象とするものではない。 However, the soils described in Patent Documents 4 and 5 are intended for the odors of ammonia and various sulfides from food residues and livestock wastes, and tobacco odors (particularly nicotine and nitrogen oxides). It is not intended for living odors such as nitrogen compounds, acetaldehyde, ammonia, acetic acid, etc.) and pet odors.
また、特許文献６に記載の土砂処理剤は、微生物分解によって発生する臭気を対象とするものではあるが、粉塵の発生を防止するために水系樹脂を必須の構成要件とするものとなっている。従って、係る土砂処理剤を室内の空気浄化に用いた場合には、水系樹脂が障害となって土壌中の微生物の活性が低下してしまうという課題がある。 Moreover, although the earth and sand treatment agent of patent document 6 is intended for the odor generated by microbial decomposition, the water-based resin is an essential constituent requirement in order to prevent the generation of dust. . Therefore, when such a soil treatment agent is used for indoor air purification, there is a problem that the activity of microorganisms in the soil decreases due to the water-based resin becoming an obstacle.
今回、本願発明者らは鋭意検討した結果、活性炭と特定の植物と（必要に応じてゼオライト）を併用することによって、単なる加算効果ではなく相乗効果が発現し、高い空気浄化効果（特に、タバコ臭に対する脱臭・消臭効果）を発現させることができるという知見を得た。 As a result of intensive studies, the inventors of the present application have found that a combination of activated carbon and a specific plant (if necessary, zeolite) produces a synergistic effect rather than a simple additive effect, and a high air purification effect (especially tobacco) The present inventors have found that a deodorizing / deodorizing effect on odor can be expressed.

まず、実施例２および比較例１の空気浄化用土壌３ｇを３Ｌのテドラーバックに入れた。次に、係るテドラーバックに排気ガスの成分である二酸化窒素を５ｐｐｍ封入した。そして、検知管を用いて時間経過に伴う二酸化窒素の濃度を測定することによって浄化性能（土壌との接触による浄化性能）の評価を行った。
また、封入ガスをタバコ臭の成分であるアセトアルデヒド（封入濃度６５ｐｐｍ）に変更し、同様の評価を行った。結果を図６、７に示す。
(Evaluation Test 1)
First, 3 g of air purification soil of Example 2 and Comparative Example 1 was placed in a 3 L Tedlar bag. Next, 5 ppm of nitrogen dioxide, which is a component of exhaust gas, was sealed in the Tedlar bag. And the purification performance (purification performance by contact with soil) was evaluated by measuring the concentration of nitrogen dioxide over time using a detector tube.
Moreover, the enclosed gas was changed to the acetaldehyde (encapsulation concentration 65 ppm) which is a component of tobacco odor, and the same evaluation was performed. The results are shown in FIGS.
（評価試験２）
まず、タバコの煙を封入した３Ｌのテドラーバック、実施例および比較例の空気浄化用土壌を充填したカラム（長さ１５０ｍｍ、直径１６ｍｍ）、空のテドラーバックを用意した。次に、タバコの煙を封入したテドラーバックとカラムの一方をコック付きのシリコンチューブで連結するとともに、カラムの他方と空のテドラーバックをシリコンチューブで連結した。次に、コックを開いた後、タバコの煙を封入したテドラーバックを押しつぶすことによってタバコの煙をカラム（空気浄化用土壌）に通過させ、通過後の空気を空のテドラーバックに回収した。
そして、回収した空気について、官能評価による臭気評価を行うことによって浄化性能（土壌を通過させることによる浄化性能）の評価を行った。具体的には、臭気指数規制ガイドライン（環境省発行）に準拠した０〜５までの６段階で評価した。結果を表１に示す。
また、実施例２および比較例１の空気浄化用土壌を通過した後の空気については、検知管を用いて臭気成分（アンモニア、アセトアルデヒド、酢酸）の濃度測定を行った。結果を図８に示す。
(Evaluation test 2)
First, a 3 L Tedlar bag filled with tobacco smoke, a column (length: 150 mm, diameter: 16 mm) filled with air purification soil of Examples and Comparative Examples, and an empty Tedlar bag were prepared. Next, one of the column and the Tedlar bag enclosing tobacco smoke was connected by a silicone tube with a cock, and the other column and the empty Tedlar bag were connected by a silicon tube. Next, after opening the cock, the tobacco smoke was passed through a column (air purification soil) by crushing the tedlar bag containing tobacco smoke, and the air after passing was collected in an empty tedlar bag.
And about the collect | recovered air, purification performance (purification performance by allowing soil to pass through) was evaluated by performing odor evaluation by sensory evaluation. Specifically, it was evaluated in 6 stages from 0 to 5 in accordance with the Odor Index Index Guidelines (issued by the Ministry of the Environment). The results are shown in Table 1.
Moreover, about the air after passing through the air purification soil of Example 2 and Comparative Example 1, the concentration of odor components (ammonia, acetaldehyde, acetic acid) was measured using a detector tube. The results are shown in FIG.
その結果、図６、７に示すとおり、本発明に係る空気浄化用土壌（実施例２）については比較例１の土壌に比べて二酸化窒素およびアセトアルデヒドの浄化性能が高くなり、単純に接触する場合においても高い浄化効果を発現することが確認された。 As a result, as shown in FIGS. 6 and 7, the air purification soil (Example 2) according to the present invention has higher purification performance of nitrogen dioxide and acetaldehyde than the soil of Comparative Example 1 and is simply in contact with the soil. It was also confirmed that a high purification effect was exhibited.
次に、表１に示すとおり、本発明に係る空気浄化用土壌は臭気などの浄化対象成分を含む空気を通過させることによって浄化対象成分（特にタバコ臭）をほぼ完全に浄化できることが確認された。 Next, as shown in Table 1, it was confirmed that the soil for air purification according to the present invention can purify the purification target component (especially tobacco odor) almost completely by passing air containing the purification target component such as odor. .
また、図８に示すとおり、タバコに含まれる臭気成分の濃度評価においても浄化が出来ていることが確認された。ここで、タバコ臭については臭気成分の濃度を低減するよりも臭い自体を除去することが難しい臭気であることが知られている。従って、臭い自体を除去することができる本発明に係る空気浄化用土壌は、タバコ臭に代表される生活臭を浄化する有用な土壌と成り得ることが確認できた。 Moreover, as shown in FIG. 8, it was confirmed that purification was also possible in the concentration evaluation of the odor component contained in the tobacco. Here, it is known that the tobacco odor is an odor that is more difficult to remove than the odor component concentration is reduced. Therefore, it has confirmed that the soil for air purification | cleaning which concerns on this invention which can remove odor itself can turn into a useful soil which purifies the life odor represented by the tobacco odor.
本発明の空気浄化用土壌は、タバコ臭、ペット臭、トイレ臭、生ごみ臭などのいわゆる生活臭の浄化に用いることができる。 The soil for air purification of the present invention can be used for purification of so-called daily odors such as tobacco odor, pet odor, toilet odor, and garbage odor.
