Description

本発明は、塩基性、酸性、硫黄系及びアルデヒド系ガスから成る複合臭気の脱臭が可能な脱臭剤に関する。   The present invention relates to a deodorizer capable of deodorizing a complex odor composed of basic, acidic, sulfur-based and aldehyde-based gases.

下水、し尿、焼却場等のプラント設備からは、さまざまな種類の悪臭が日々発生している。これらの悪臭には硫化水素などの酸性ガス、アンモニアなどの塩基性ガス、更には硫化メチルなどの硫黄系ガスなどが含まれており、それぞれのガスの除去方法が問題とされている。現在、この様な複合臭気の脱臭は、各臭気に対応した吸着剤の積層において行われているが、問題となる複合臭気には上述のような原因物質が多数含まれているため、これらの臭気物質全般に対して等しく除去能を有する脱臭剤が必要とされている。   Various types of bad odors are generated every day from plant facilities such as sewage, human waste and incineration plants. These malodors include acidic gases such as hydrogen sulfide, basic gases such as ammonia, and sulfur-based gases such as methyl sulfide, and the methods for removing these gases are problematic. At present, such deodorization of complex odors is carried out in a stack of adsorbents corresponding to each odor, but since the problematic complex odor contains many causative substances as described above, these There is a need for deodorizers that are equally capable of removing odorous substances.

悪臭を除去する方法として、一般的には芳香剤を利用するマスキング方法、活性炭やシリカゲル等の物理的吸着に依存する方法、等が挙げられる。しかし、マスキング方法は悪臭成分の根本的除去を目的としたものではなく、芳香剤そのものの臭いが問題となることもある。また、物理吸着による方法は、吸着可能な悪臭成分が使用する吸着剤の型に依存し、例えば、活性炭ではアンモニア、トリメチルアミンなどの塩基性の臭気に対して全く効果を上げることができない。同様に、一般的な下水処理施設やゴミ処理施設等における悪臭ガスの主要成分である硫黄系ガスに対しても、物理的吸着だけでは十分に除去することができない。   As a method for removing malodor, generally, a masking method using a fragrance, a method depending on physical adsorption such as activated carbon or silica gel, and the like can be mentioned. However, the masking method is not intended to fundamentally remove malodorous components, and the odor of the fragrance itself may be a problem. Further, the method by physical adsorption depends on the type of adsorbent used by the adsorbable malodor component, and for example, activated carbon cannot at all be effective against basic odors such as ammonia and trimethylamine. Similarly, sulfur-based gas, which is a main component of malodorous gas in general sewage treatment facilities and garbage treatment facilities, cannot be sufficiently removed by physical adsorption alone.

通常、これらの問題点を解決する方法としては化学的方法が考えられる。例えば、酸性臭気または塩基性臭気に対しては中和反応を利用した悪臭除去方法が用いられており、この方法によれば、硫化水素等の酸性臭気を塩基性吸着剤により除去し、あるいはアンモニア、トリメチルアミン等の塩基性臭気を酸性吸着剤により除去することが可能である。しかしながら、塩基性吸着剤と酸性吸着剤は、その性質上同一担体に同時に坦持させた状態や、同一液体中に同時に分散させた状態では互いに反応を起こし、その結果失活してしまう。更に、その他の異なる化学的性質を有する悪臭を同様の方法で脱臭するためには、その際に使用する薬剤についての反応性も考慮する必要がある。その結果、これらのことが複合臭気の脱臭を目的とした吸着剤を開発する上での障害となっていた。   Usually, a chemical method can be considered as a method for solving these problems. For example, a bad odor removal method using a neutralization reaction is used for an acidic odor or a basic odor. According to this method, an acidic odor such as hydrogen sulfide is removed by a basic adsorbent or ammonia. Basic odors such as trimethylamine can be removed with an acidic adsorbent. However, a basic adsorbent and an acidic adsorbent react with each other in a state where they are simultaneously supported on the same carrier or in a state where they are simultaneously dispersed in the same liquid, and are deactivated as a result. Furthermore, in order to deodorize other malodors having different chemical properties in the same manner, it is necessary to consider the reactivity of the drug used at that time. As a result, these have been obstacles in developing an adsorbent for the purpose of deodorizing complex odors.

近年、上記欠点の克服を目指した、単一吸着剤で塩基性ガス及び酸性ガス、更には硫黄系ガスの脱臭が可能なものも発明されている(特許文献1参照)。しかし、アルデヒド系ガスの脱臭は、吸着剤に対する物理的吸着に依存するところが大きく、当該ガスに対する除去能は十分とはいえなかった。   In recent years, a single adsorbent capable of deodorizing basic gas and acid gas, and further sulfur-based gas has been invented with the aim of overcoming the above drawbacks (see Patent Document 1). However, the deodorization of the aldehyde-based gas largely depends on the physical adsorption to the adsorbent, and the removal ability for the gas cannot be said to be sufficient.

また、上記吸着剤とは反対に、アルデヒド系ガスを含む複合臭気を脱臭する吸着剤も発明されていたが(特許文献2参照)、酸性及び塩基性臭気、並びにアルデヒド系のガスに対しては良好な吸着能を示すものの、硫黄系ガスに対する除去性能が低いという問題があった。   In contrast to the above adsorbents, adsorbents that deodorize complex odors containing aldehyde gases have also been invented (see Patent Document 2), but for acidic and basic odors and aldehyde gases. Although it showed good adsorption ability, there was a problem that the removal performance for sulfur-based gas was low.

以上のことより、塩基性及び酸性ガスに対する吸着能を維持しつつ、硫黄系ガスとアルデヒド系ガスの両者に対して優れた吸着能を同時に担体に持たせるには、それらの目的に適合した互いに反応しない薬剤を選択する必要がある。しかしながら、実際にはこのような条件を満たす薬剤を選択することは困難であった。   From the above, in order to maintain the adsorption ability for both the sulfur-based gas and the aldehyde-based gas at the same time while maintaining the adsorption ability for basic and acidic gases, the carriers that are suitable for these purposes can be used. It is necessary to select drugs that do not respond. However, in practice, it has been difficult to select a drug that satisfies such conditions.

本発明の課題は、塩基性、酸性及び硫黄系ガスの脱臭性能を維持しつつ、従来の方法では脱臭が困難であったアルデヒド系のガスに対しても優れた脱臭性能を有する複合臭気脱臭剤を提供することにある。   The object of the present invention is to maintain a deodorizing performance of basic, acidic, and sulfur-based gases, and a composite odor deodorizing agent having an excellent deodorizing performance for aldehyde-based gases that have been difficult to deodorize by conventional methods. Is to provide.

上記課題を解決するために本発明者らが検討を重ねた結果、p-アミノ安息香酸の酸性塩と、無機酸と、臭素および/または臭化物とを多孔質体に坦持させたものが、酸性、塩基性、アルデヒド系、硫黄系のガスのいずれをも良好に吸着することが明らかとなった。   As a result of repeated investigations by the present inventors in order to solve the above-mentioned problems, a material in which an acidic salt of p-aminobenzoic acid, an inorganic acid, bromine and / or bromide is supported on a porous material, It was revealed that any of acidic, basic, aldehyde-based, and sulfur-based gases adsorbed well.

具体的には、本発明は(1)多孔質体にp-アミノ安息香酸の酸性塩と、無機酸と、臭素および/または臭化物とが坦持されていることを特徴とする複合臭気脱臭剤、(2)坦持量として、多孔質体100重量部に対し、p-アミノ安息香酸もしくは酸性塩が0.5〜10重量部、無機酸が1〜20重量部、臭素および/または臭化物が1〜20重量部であることを特徴とする前記(1)記載の複合臭気脱臭剤、である。   Specifically, the present invention provides (1) a composite odor deodorant characterized in that an acidic salt of p-aminobenzoic acid, an inorganic acid, and bromine and / or bromide are supported on the porous body. (2) The supported amount is 0.5 to 10 parts by weight of p-aminobenzoic acid or acidic salt, 1 to 20 parts by weight of inorganic acid, bromine and / or bromide with respect to 100 parts by weight of the porous body. It is 1-20 weight part, The composite odor deodorizer of the said (1) description characterized by the above-mentioned.

本発明は、無機酸、臭素および/または臭化物にp-アミノ安息香酸の酸性塩を加えた複合吸着剤を多孔質体に坦持することにより、酸性、塩基性、硫黄系、アルデヒド系の臭気全てをバランス良く除去することができる。   The present invention provides a porous adsorbent containing a composite adsorbent obtained by adding an acidic salt of p-aminobenzoic acid to an inorganic acid, bromine and / or bromide, thereby causing an acidic, basic, sulfur-based or aldehyde-based odor. All can be removed in a well-balanced manner.

本発明の脱臭剤は、多孔質体にp-アミノ安息香酸の酸性塩と、無機酸と、臭素および/または臭化物とが坦持されていることを特徴とする。   The deodorizer of the present invention is characterized in that an acidic salt of p-aminobenzoic acid, an inorganic acid, and bromine and / or bromide are supported on a porous body.

本発明のp-アミノ安息香酸の酸性塩は、p-アミノ安息香酸のアミノ基がアンモニウムイオン化したものである。本発明では、p-アミノ安息香酸の酸性塩を添加してもよいし、p-アミノ安息香酸と酸を添加して酸性塩化させてもよい。このための酸は後記の無機酸でもよい。   The acidic salt of p-aminobenzoic acid of the present invention is one in which the amino group of p-aminobenzoic acid is ammonium ionized. In the present invention, an acidic salt of p-aminobenzoic acid may be added, or p-aminobenzoic acid and an acid may be added for acid chloride. The acid for this purpose may be an inorganic acid described later.

多孔質体に坦持されたp-アミノ安息香酸の酸性塩は、酸性物質であるにもかかわらず、酸性臭気である低級アルデヒド系のガスの除去に有効である。当該酸性塩の性質は、アミノ酸中の酸性塩化したアミノ基とカルボキシル基が同時的且つ協奏的に作用し、低級アルデヒド類を化学的に吸着除去あるいは化学的に不活性化することによって生ずると推定される。また、酸性塩化していることにより、アミノ基とカルボキシル基がカップリングして双性イオン化することがなく、吸着剤としての活性が低下しないという利点がある。   The acidic salt of p-aminobenzoic acid supported on the porous material is effective in removing a lower aldehyde-based gas that is an acidic odor, despite being an acidic substance. The nature of the acid salt is presumed to be caused by the simultaneous and concerted action of the acid-chlorinated amino group and carboxyl group in the amino acid, which chemically removes or inactivates the lower aldehydes. Is done. In addition, the acidic chlorination has the advantage that the amino group and the carboxyl group are not coupled to form zwitterion and the activity as an adsorbent is not lowered.

本発明の無機酸は、多孔質体上において塩基性ガスを中和反応により除去する役割を果たすものである。また、この無機酸は、上述のように出発物質であるp-アミノ安息香酸を酸性塩化するための酸として作用させてもよく、その場合は無機酸を過剰量で使用すればよい。上記目的以外にも、本発明の無機酸は、後述のように本発明の臭素または臭化物の吸着除去活性を維持する役割も果たす。   The inorganic acid of the present invention plays a role of removing basic gas by neutralization reaction on the porous body. Further, this inorganic acid may act as an acid for acidifying the starting material p-aminobenzoic acid as described above, in which case the inorganic acid may be used in excess. In addition to the above purpose, the inorganic acid of the present invention also plays a role of maintaining the bromine or bromide adsorption removal activity of the present invention as described later.

本発明に用いられる無機酸としては、硫酸、リン酸、塩酸、硝酸などが挙げられるが、硫酸を用いることが好ましい。   Examples of the inorganic acid used in the present invention include sulfuric acid, phosphoric acid, hydrochloric acid, and nitric acid, but it is preferable to use sulfuric acid.

本発明の臭素は、硫化水素などの硫黄系ガスを酸化除去するのに有効である。臭化物も同様の理由で使用され、その反応機構は以下のように説明される。1)本発明の臭化物と、共存する酸との反応により臭化水素が生じる。2)臭化水素が酸化することにより臭化水素酸が生成する。3)生じた臭化水素酸が硫化物を酸化除去する。   The bromine of the present invention is effective for oxidizing and removing sulfur-based gases such as hydrogen sulfide. Bromide is also used for the same reason and its reaction mechanism is explained as follows. 1) Hydrogen bromide is generated by the reaction of the bromide of the present invention with a coexisting acid. 2) Hydrobromic acid is produced by the oxidation of hydrogen bromide. 3) The resulting hydrobromic acid oxidizes and removes sulfides.

上記反応3)の後、硫化物の酸化に使用された臭化水素酸は再び臭化水素となり、その結果反応2)へと続く循環系が構成される。ここで、上述のように本発明の無機酸はこのサイクルを維持する役割も果たす。   After the above reaction 3), the hydrobromic acid used for the oxidation of the sulfide again becomes hydrogen bromide, resulting in the construction of a circulation system that continues to reaction 2). Here, as described above, the inorganic acid of the present invention also serves to maintain this cycle.

本発明で使用される臭化物としては、臭化カリウム、臭化ナトリウム、臭化アンモニウム等が挙げられるが、臭化カリウムを用いることが好ましい。   Examples of the bromide used in the present invention include potassium bromide, sodium bromide, ammonium bromide and the like, but it is preferable to use potassium bromide.

上記成分は多孔質体に高分散に坦持されることが好ましい。ここで、本発明に用いられる多孔質体としては、活性炭、セピオライト、パリゴルスカイト、ゼオライト、活性炭素繊維、活性アルミナ、セピオライト混合紙、シリカゲル、活性白土、パーミキュライト、珪藻土などの無機質多孔質体のほか、パルプ、繊維、布、高分子多孔質体などの有機質多孔質体が挙げられる。多孔質体は、脱臭が意図される悪臭の種類に依存して選択することができる。好ましくは、比表面積が大きい多孔質体が使用される。比表面積の増大に伴い吸着能が向上するためである。   It is preferable that the above components are supported on the porous body with high dispersion. Here, as a porous body used in the present invention, in addition to an inorganic porous body such as activated carbon, sepiolite, palygorskite, zeolite, activated carbon fiber, activated alumina, sepiolite mixed paper, silica gel, activated clay, permiculite, diatomaceous earth, Organic porous bodies, such as a pulp, a fiber, cloth, and a polymeric porous body, are mentioned. The porous body can be selected depending on the type of malodor intended to be deodorized. Preferably, a porous body having a large specific surface area is used. This is because the adsorption capacity is improved with an increase in the specific surface area.

上記成分を多孔質体に高分散に坦持せしめる方法として、上記成分を水またはその他の可溶性溶媒に溶解し、その溶液を多孔質体に含浸させる方法がある。このように溶液状のものを含浸させることにより、各成分を多孔質体に同時に且つ均一に高分散状態で坦持させることができる。多孔質体は、上記組合せの各成分をその構造中の細孔内に均一に保持し、悪臭ガスに対する接触面積を広げ、これらの成分による悪臭ガスの吸着性能を向上させる。当該脱臭剤においては、p-アミノ安息香酸の酸性塩と、無機酸と、臭素および/または臭化物とが大きな比表面積を有した多孔質体に高分散状態で坦持されているので、各成分がその能力を最大限に発揮することができる。   As a method of allowing the above-mentioned component to be highly dispersed in the porous body, there is a method in which the above-described component is dissolved in water or other soluble solvent and the solution is impregnated into the porous body. By impregnating the solution in this way, each component can be supported on the porous body simultaneously and uniformly in a highly dispersed state. The porous body holds each component of the above combination uniformly in the pores in the structure, widens the contact area with the malodorous gas, and improves the adsorption performance of the malodorous gas by these components. In the deodorizing agent, the acid salt of p-aminobenzoic acid, the inorganic acid, and bromine and / or bromide are supported in a highly dispersed state on a porous body having a large specific surface area. Can fully demonstrate its abilities.

上記成分の坦持量は、多孔質体100重量部に対し、p-アミノ安息香酸もしくは酸性塩が0.5〜10重量部、無機酸が1〜20重量部、臭素および/または臭化物が1〜20重量部であることが好ましい。更に好ましくは、上記成分の坦持量は、多孔質体100重量部に対し、p-アミノ安息香酸もしくは酸性塩が3〜6重量部、無機酸が6〜12重量部、臭素および/または臭化物が6〜12重量部である。   The supported amount of the above components is 0.5 to 10 parts by weight of p-aminobenzoic acid or acidic salt, 1 to 20 parts by weight of inorganic acid, 1 part of bromine and / or bromide with respect to 100 parts by weight of the porous body. It is preferable that it is -20 weight part. More preferably, the supported amount of the above components is 3 to 6 parts by weight of p-aminobenzoic acid or acid salt, 6 to 12 parts by weight of inorganic acid, bromine and / or bromide with respect to 100 parts by weight of the porous body. Is 6 to 12 parts by weight.

上記坦持量の割合は、酸性、塩基性、硫黄系、アルデヒド系のガスをバランス良く吸着するために必要とされるものであるが、各成分の坦持量は、目的の悪臭の成分に依存して適宜選択することができる。   The ratio of the supported amount is necessary for adsorbing acidic, basic, sulfur-based, and aldehyde-based gases in a balanced manner, but the supported amount of each component depends on the target malodorous component. It can be selected appropriately depending on the situation.

本発明の脱臭剤は、その製造方法に関して限定されるものではない。1つの製法例としては、上述のように吸着剤の各成分を水に溶解し、続いてこれらを無機酸で処理したヤシ殻活性炭に吸水坦持せしめ、乾燥させる方法がある。   The deodorizer of this invention is not limited regarding the manufacturing method. As one example of the production method, there is a method in which each component of the adsorbent is dissolved in water as described above, and then these are absorbed on coconut shell activated carbon treated with an inorganic acid and dried.

最後に、本発明の構成要素の1つである臭素および臭化物は、従来その臭いから家庭用の吸着剤に使用することが敬遠されてきたが、以下の実施例に示すように硫黄系ガスに対して優れた吸着能を有している。この様な観点から、本発明は硫黄系ガスの悪臭が問題となっている下水処理施設、ゴミ処理施設等において好適に使用することができる。   Finally, bromine and bromide, which are one of the components of the present invention, have conventionally been avoided from being used for adsorbents for household use due to their odor, but as shown in the following examples, It has an excellent adsorption capacity. From this point of view, the present invention can be suitably used in sewage treatment facilities, waste treatment facilities, and the like, where the bad odor of sulfur-based gas is a problem.

以下に実施例、比較例を挙げて本発明を更に具体的に説明するが、本発明はこれらに限定されるものではない。   Hereinafter, the present invention will be described more specifically with reference to examples and comparative examples, but the present invention is not limited thereto.
