Description

この発明は、環境測定等における排ガスなどの気体試料中から塩化水素を除去し、有機系ハロゲン化合物を取り出す装置およびその方法に関する。 The present invention, hydrogen chloride is removed from the flue gas of which the gas material specimen in environmental measurement etc., an apparatus and method takes out the organic halogen compound.

従来より、塩化水素や塩化ナトリウムなどの無機系ハロゲン化合物と、クロロベンゼンやダイオキシン類などの有機系ハロゲン化合物の両方を含有する排ガスや排水などの試料中から、無機系ハロゲン化合物を除去して、有機系ハロゲン化合物の濃度を測定する方法が提案されている（例えば、特許文献１参照）。   Conventionally, inorganic halogen compounds are removed from samples such as exhaust gas and waste water containing both inorganic halogen compounds such as hydrogen chloride and sodium chloride, and organic halogen compounds such as chlorobenzene and dioxins, and organic A method for measuring the concentration of a halogenated halogen compound has been proposed (see, for example, Patent Document 1).

図２に、この除去方法の概略模式図を示す。図２（ａ）は、活性炭４に無機系ハロゲン化合物と有機系ハロゲン化合物の両方を吸着させる工程を示した模式図であり、（ｂ）は、活性炭４から無機系ハロゲン化合物を除去する工程を示した模式図である。   FIG. 2 shows a schematic diagram of this removal method. FIG. 2A is a schematic diagram showing a process of adsorbing both an inorganic halogen compound and an organic halogen compound to the activated carbon 4, and FIG. 2B shows a process of removing the inorganic halogen compound from the activated carbon 4. It is the shown schematic diagram.

まず、図２（ａ）に示した最初の工程では、無機系ハロゲン化合物と有機系ハロゲン化合物の両方を含有する排ガスや排水などの試料を、活性炭４に通過させて、無機系ハロゲン化合物と有機系ハロゲン化合物の両方をこの活性炭４に吸着させる。   First, in the first step shown in FIG. 2 (a), a sample such as exhaust gas or waste water containing both an inorganic halogen compound and an organic halogen compound is passed through activated carbon 4, and the inorganic halogen compound and organic Both of the halogenated compounds are adsorbed on the activated carbon 4.

次いで、図２（ｂ）に示した工程では、この活性炭４にハロゲンイオンを含まない、例えば硝酸カリウム水溶液を通過させて、無機系ハロゲン化合物のみを溶出させて除去する。   Next, in the step shown in FIG. 2 (b), the activated carbon 4 is passed through, for example, an aqueous potassium nitrate solution containing no halogen ions, and only the inorganic halogen compound is eluted and removed.

処理後の活性炭４には、有機系ハロゲン化合物のみが吸着されていることから、この活性炭４を燃焼炉で酸素と共に燃焼し、有機系ハロゲン化合物を分解して測定・分析することで、試料中の有機系ハロゲン化合物の濃度が求められる。
特開昭５８−１５３１６３号公報 Since only the organic halogen compound is adsorbed on the activated carbon 4 after the treatment, the activated carbon 4 is burned with oxygen in a combustion furnace, and the organic halogen compound is decomposed and measured and analyzed. The concentration of the organic halogen compound is required.
JP 58-153163 A

しかしながら、特許文献１に係る方法は、手作業を伴うものであり、また、試料中のハロゲン化合物を一旦活性炭に吸着させてから処理するものであるため、常時連続的に機械で自動化して有機系ハロゲン化合物の濃度をモニタリングするのは困難であるという問題があった。特に、試料がダイオキシン類のような人体に有害な有機系ハロゲン化合物を含有する場合には、手作業を伴うことなく機械で全自動化したいという要望が強かった。   However, the method according to Patent Document 1 involves manual work, and since the halogen compound in the sample is once adsorbed on activated carbon and then processed, it is always continuously automated by a machine and organic. There is a problem that it is difficult to monitor the concentration of the halogenated halogen compound. In particular, when a sample contains an organic halogen compound that is harmful to the human body, such as dioxins, there is a strong demand for full automation by a machine without manual work.

また、硝酸カリウム水溶液で活性炭から無機系ハロゲン化合物を溶出させて除去するため、操作が煩雑であり、また発生した廃液の処理を伴うという問題もあった。   In addition, since the inorganic halogen compound is eluted and removed from the activated carbon with an aqueous potassium nitrate solution, the operation is complicated, and there is also a problem that it involves treatment of the generated waste liquid.

本発明は、手作業を伴うことなく、除去効率が高く、簡単に自動化することができ、廃液を発生することなく、排ガスなどの気体試料中の塩化水素を除去し、気体試料中から有機系ハロゲン化合物を取り出すことができる装置及びその方法を得ることにある。 The present invention, without manual removal efficiency is high, it can easily be automated, without generating waste liquid, to remove the hydrogen chloride flue gas of which the gas sample, the gas sample An object of the present invention is to provide an apparatus and method for extracting an organic halogen compound.

以下、本発明の有機系ハロゲン化合物取出装置の一例を図面に示して詳細に説明する。 Hereinafter, an example of the organic halogen compound take-out device of the present invention will be described in detail with reference to the drawings.

図１は、本発明の実施の形態に係る無機系ハロゲン化合物除去装置２を備えた有機系ハロゲン化合物取出装置１の概略構成図である。この有機系ハロゲン化合物取出装置１は、本実施形態に係る無機系ハロゲン化合物除去装置２と、その下流に接続された有機系ハロゲン化合物吸着装置３とから概略構成されている。   FIG. 1 is a schematic configuration diagram of an organic halogen compound extraction apparatus 1 including an inorganic halogen compound removal apparatus 2 according to an embodiment of the present invention. This organic halogen compound take-out device 1 is generally configured by an inorganic halogen compound removing device 2 according to this embodiment and an organic halogen compound adsorbing device 3 connected downstream thereof.

この有機系ハロゲン化合物取出装置１は、無機系ハロゲン化合物と有機系ハロゲン化合物の両方を含有する排ガスや排水などの試料を、無機系ハロゲン化合物除去装置２に通過させて無機系ハロゲン化合物を除去した後、有機系ハロゲン化合物吸着装置３に通過させて有機系ハロゲン化合物を吸着して取出すと共に、残りの不要な成分を排出できるようになっている。   In this organic halogen compound take-out device 1, a sample such as exhaust gas or waste water containing both an inorganic halogen compound and an organic halogen compound is passed through an inorganic halogen compound removing device 2 to remove the inorganic halogen compound. Thereafter, the organic halogen compound is passed through the organic halogen compound adsorbing device 3 to be adsorbed and taken out, and the remaining unnecessary components can be discharged.

無機系ハロゲン除去装置２は、試料から無機系ハロゲン化合物のみを除去するもので、金属銀を有するものである。例えば、金属銀粒子や金属銀を担持したプラスチック、セラミック、およびセルロースからなる群から選択される一種以上の粒子であるのが好ましい。粒子状の場合、粒径０．１〜２．０ｍｍが好ましく、粒径０．４〜０．９ｍｍがより好ましい。   The inorganic halogen removing apparatus 2 removes only the inorganic halogen compound from the sample and has metallic silver. For example, it is preferably one or more kinds of particles selected from the group consisting of metal silver particles, plastics carrying metal silver, ceramics, and cellulose. In the case of particles, a particle size of 0.1 to 2.0 mm is preferable, and a particle size of 0.4 to 0.9 mm is more preferable.

無機系ハロゲン化合物除去装置２に粒径０．４〜０．９ｍｍの金属銀粒子を用いることにより、試料中のハロゲンやハロゲン化物などの無機系ハロゲン化合物のみをハロゲン化銀として吸着し、高い除去効率で除去することができる。 By using metallic silver particles with a particle size of 0.4 to 0.9 mm in the inorganic halogen compound removal device 2, only inorganic halogen compounds such as halogens and halides in the sample are adsorbed as silver halide for high removal. Can be removed with efficiency.

また、従来技術の活性炭を用いる場合と異なり、無機系ハロゲン化合物のみを吸着するため、硝酸カリウム水溶液で無機系ハロゲン化合物を洗浄して有機系ハロゲン化合物を残すような煩雑な手作業を行うことなく処理することができ、廃液を発生することなく、簡単に自動化することができる。   Also, unlike the case of using the activated carbon of the prior art, only the inorganic halogen compound is adsorbed, so that the treatment is performed without performing complicated manual work such as washing the inorganic halogen compound with an aqueous potassium nitrate solution to leave the organic halogen compound. It can be easily automated without generating waste liquid.

また、有機系ハロゲン化合物吸着装置３は、試料からハロゲン化ベンゼン、ハロゲン化フェノール、ダイオキシン類等の有機系ハロゲン化合物を吸着する吸着剤を充填してなるものである。このような吸着剤としては、例えば、活性炭やシリカゲル等が挙げられる。また、有機系ハロゲン化合物を吸着すると共に、加熱によりこれらを脱離可能な吸着剤であってもよい。このような吸着剤としては、例えば、分子量の大きい芳香族系の有機系ハロゲン化合物を選択的に吸着し、ジクロロメタンのような分子量の小さい有機系ハロゲン化合物を吸着しない性質を有するＸＡＤ−２（スチレン−ジビニルベンゼン共重合体）樹脂、ＴｅｎａＸ（２，６−ジフェニル−ｐ−フェニレンオキサイド）樹脂などを用いることができる。   The organic halogen compound adsorbing apparatus 3 is formed by filling an adsorbent that adsorbs organic halogen compounds such as halogenated benzene, halogenated phenol, and dioxins from a sample. Examples of such an adsorbent include activated carbon and silica gel. Further, it may be an adsorbent that adsorbs organic halogen compounds and can desorb them by heating. As such an adsorbent, for example, XAD-2 (styrene) having a property of selectively adsorbing an aromatic organic halogen compound having a large molecular weight and not adsorbing an organic halogen compound having a low molecular weight such as dichloromethane. -Divinylbenzene copolymer) resin, TenaX (2,6-diphenyl-p-phenylene oxide) resin, and the like can be used.

上記有機系ハロゲン化合物吸着装置３は、その吸着剤が有機系ハロゲン化合物のみならず無機系ハロゲン化合物も共に吸着する性質を有するため、無機系ハロゲン除去装置２の下流に配置することにより、有機系ハロゲン化合物のみを選択的に吸着させることができる。   The organic halogen compound adsorbing device 3 has a property that the adsorbent adsorbs not only organic halogen compounds but also inorganic halogen compounds, so that it is disposed downstream of the inorganic halogen removing device 2 to provide an organic system. Only halogen compounds can be selectively adsorbed.

そして、この有機系ハロゲン化合物取出装置１では、無機系ハロゲン化合物除去装置２と有機系ハロゲン化合物吸着装置３とを組合わせて用いることにより、有機系ハロゲン化合物のみを選択的に有機系ハロゲン化合物吸着装置３に吸着させて取り出すことができる。   And in this organic halogen compound take-out device 1, by using the inorganic halogen compound removing device 2 and the organic halogen compound adsorbing device 3 in combination, only the organic halogen compound is selectively adsorbed. It can be taken out by adsorbing to the device 3.

以下、この有機系ハロゲン化合物取出装置１を用いた無機系ハロゲン化合物の除去方法と有機系ハロゲン化合物の取出方法について説明する。   Hereinafter, a method for removing an inorganic halogen compound and a method for removing an organic halogen compound using the organic halogen compound take-out device 1 will be described.

試料となるのは、ごみ焼却場や産業廃棄物焼却場などの焼却炉等、製鋼用電気炉、鉄鋼業焼結施設、亜鉛回収施設、アルミニウム合金製造設備などから排出される排ガス・排水などの気体または液体、あるいはその作業環境大気、一般大気、一般生活排水、河川・湖沼水などであって、ハロゲンやハロゲン化物等の無機系ハロゲン化合物及び／又はハロゲン化ベンゼン、ハロゲン化フェノール、ダイオキシン類等、特にＣｌ、Ｂｒで置換された分子量の大きい芳香族系の有機系ハロゲン化合物を含むものである。   Samples include waste incinerators such as garbage incinerators and industrial waste incinerators, etc., electric furnaces for steel making, steel industry sintering facilities, zinc recovery facilities, aluminum alloy manufacturing facilities, etc. Gas or liquid, or the working environment air, general air, general wastewater, river / lake water, etc., and inorganic halogen compounds such as halogen and halides and / or halogenated benzene, halogenated phenol, dioxins, etc. In particular, it contains an aromatic organic halogen compound having a large molecular weight and substituted with Cl or Br.

まず、あらかじめフィルターを通過してダスト等を除去した試料を、無機系ハロゲン除去装置２に通過させる。また、上記フィルターとしては、ハロゲン化合物を吸着せずに、ダスト・ミスト等を除去できるものであれば、特に限定されるものでなく、例えば、ガラス繊維製フィルター、合成繊維製フィルター、セラミック製フィルター等が挙げられる。   First, the sample from which dust and the like have been removed by passing through a filter in advance is passed through the inorganic halogen removing apparatus 2. The filter is not particularly limited as long as it can remove dust, mist, etc. without adsorbing a halogen compound. For example, a glass fiber filter, a synthetic fiber filter, a ceramic filter Etc.

無機系ハロゲン除去装置２により、無機系ハロゲン化合物を除去した試料は、有機系ハロゲン化合物吸着装置３に送られ、試料中の有機系ハロゲン化合物が吸着される。有機系ハロゲン化合物吸着装置３を通過した試料は、系外に排出される。   The sample from which the inorganic halogen compound has been removed by the inorganic halogen removing device 2 is sent to the organic halogen compound adsorption device 3, where the organic halogen compound in the sample is adsorbed. The sample that has passed through the organic halogen compound adsorption device 3 is discharged out of the system.

吸着した有機系ハロゲン化合物は、吸着剤と共に別途分解装置、分析装置に送られ、吸着剤から有機系ハロゲン化合物を脱離あるいは分解させて、試料中の有機系ハロゲン化合物の濃度を測定するのに用いられる。   The adsorbed organic halogen compound is sent together with the adsorbent to a separate decomposing / analyzing device to desorb or decompose the organic halogen compound from the adsorbent and measure the concentration of the organic halogen compound in the sample. Used.

この無機系ハロゲン化合物の除去方法によれば、従来のように活性炭に無機系ハロゲン化合物と有機系ハロゲン化合物の両方を吸着させてから、硝酸カリウム水溶液で無機系ハロゲン化合物のみを溶出させて除去するという２工程を要することなく、無機系ハロゲン除去装置２に無機系ハロゲン化合物を吸着させる１工程で、簡単に試料中の無機系ハロゲン化合物を除去することができる。   According to this method for removing an inorganic halogen compound, both the inorganic halogen compound and the organic halogen compound are adsorbed on activated carbon as in the past, and then only the inorganic halogen compound is eluted and removed with an aqueous potassium nitrate solution. Without requiring two steps, the inorganic halogen compound in the sample can be easily removed in one step of adsorbing the inorganic halogen compound to the inorganic halogen removing device 2.

以下、実施例により、本発明をさらに詳しく説明する。本発明は、下記実施例に何ら制限されるものではない。   Hereinafter, the present invention will be described in more detail by way of examples. The present invention is not limited to the following examples.

［実施例１］
一般廃棄物焼却炉の排ガスを用いて、塩化水素の除去について実験を行った。まず、金属銀顆粒（粒径０．４〜０．９ｍｍ）をそれぞれ２０ｇ充填したカラムを、２本直列に連結し、無機系ハロゲン化合物除去装置を作製した。この無機系ハロゲン化合物除去装置に、塩化水素を２００ｐｐｍ含有する排ガスを通過させた。次いで、通過除去後の排ガス中の塩化水素濃度を、ＪＩＳ Ｋ０１０７（イオンクロマトグラフ法）で分析した。この結果を表１に示す。 [Example 1]
An experiment was conducted on the removal of hydrogen chloride using the exhaust gas from a general waste incinerator. First, two columns each filled with 20 g of metallic silver granules (particle size 0.4 to 0.9 mm) were connected in series to prepare an inorganic halogen compound removing apparatus. Exhaust gas containing 200 ppm of hydrogen chloride was passed through this inorganic halogen compound removal apparatus. Next, the hydrogen chloride concentration in the exhaust gas after passing through was analyzed by JIS K0107 (ion chromatography method). The results are shown in Table 1.

Figure 0004767575
Figure 0004767575

［比較例１］
１０質量％の硝酸カリウム水溶液を無機系ハロゲン化合物吸収液として用い、これに実施例１の排ガスを通過させた後、通過除去後の排ガス中の塩化水素濃度を、実施例１と同様に測定した。この結果を表１に示す。 [Comparative Example 1]
A 10 mass% potassium nitrate aqueous solution was used as the inorganic halogen compound absorbing solution, and after passing the exhaust gas of Example 1, the hydrogen chloride concentration in the exhaust gas after passing through was measured in the same manner as in Example 1. The results are shown in Table 1.

表１の結果から、除去後の排ガス中の塩化水素濃度は、実施例１の場合も比較例１の場合も０．０３ｐｐｍと大変低く、除去率は９９．９８％で、同程度の除去性能であることがわかった。   From the results in Table 1, the concentration of hydrogen chloride in the exhaust gas after removal is as low as 0.03 ppm in both cases of Example 1 and Comparative Example 1, and the removal rate is 99.98%, which is comparable removal performance. I found out that

また、実施例１では、最初白銀色であった金属銀顆粒が、排ガス中の塩化水素と反応することにより黒褐色に変化した。２本のカラムのうち、前段のカラムは約６ヶ月でほぼ全体が黒褐色となった。したがって、後段のカラムが黒褐色となり始めた時点を目安として、前段のカラムを取り外し、後段のカラムを前段に取り付けるとともに、新しいカラムを後段に設置してカラム交換を行うのが好ましいことがわかった。   Moreover, in Example 1, the metallic silver granule which was white silver initially changed to blackish brown by reacting with hydrogen chloride in the exhaust gas. Of the two columns, the former column turned almost brownish in about 6 months. Therefore, it was found that it is preferable to replace the column by removing the former column, attaching the latter column to the former stage, and installing a new column in the latter stage, with the time when the latter column starts to become blackish brown.

以上の結果から、吸着剤として粒径０．４〜０．９ｍｍの金属銀粒子を用いることにより、高い除去効率で塩化水素を除去できることがわかった。 From the above results, it was found that hydrogen chloride can be removed with high removal efficiency by using metallic silver particles having a particle size of 0.4 to 0.9 mm as the adsorbent.
