以下、本発明の粉末消火薬剤廃棄物液体肥料生成方法の第１の実施形態について図面を参照にしながら説明する。図１は、本発明の第１の実施形態における粉末消火薬剤廃棄物液体肥料生成方法のフローチャートである。 Hereinafter, a first embodiment of the method for producing a powder fire extinguishing agent waste liquid fertilizer of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart of a method for producing a powder fire extinguishing agent waste liquid fertilizer according to the first embodiment of the present invention.
まず、Ｓ１において、粉末消化薬剤廃棄物分別工程が実施される。この粉末消化薬剤廃棄物分別工程では、消火器の内部の粉末消火薬剤廃棄物を消火器から分別させる。具体的には、消火薬液吸引機を用いて、消火器内の粉末消火薬剤廃棄物を吸引し、フレコンバック内に粉末消火薬剤廃棄物を収納させる。なお、粉末消化薬剤廃棄物分別工程は任意の工程であり、消火器から分別された粉末消火薬剤廃棄物を用いる場合は粉末消化薬剤廃棄物分別工程を実施する必要がない。ここで、粉末消火薬剤廃棄物の成分は、一般的に、第一リン酸アンモニウム（重量比：３６．５％〜４５％）、硫酸アンモニウム（重量比：４０％〜６０％）、非晶質二酸化珪素（重量比：約３％）で構成され、窒素およびリンの理論濃度は窒素１２．８％〜１８．１％、リン９．７％〜１２．０％であるので、粉末消火薬剤廃棄物は肥料の三大要素である窒素、リン、カリウムの内、窒素、リンを多く含有し、肥料として用いることができる。そして、Ｓ２に進む。 First, in S1, a powder digestive medicine waste sorting step is performed. In this powder digestive chemical waste separation step, the powder fire extinguishing chemical waste inside the fire extinguisher is separated from the fire extinguisher. Specifically, the powder extinguishing agent waste in the fire extinguisher is sucked using a fire extinguisher liquid suction device, and the powder extinguishing agent waste is stored in a flexible container bag. Note that the powder digestive medicine waste separation step is an optional step, and when the powder fire extinguishing chemical waste separated from the fire extinguisher is used, it is not necessary to perform the powder digestive medicine waste separation step. Here, the components of the powder fire extinguishing agent waste generally include ammonium monophosphate (weight ratio: 36.5% to 45%), ammonium sulfate (weight ratio: 40% to 60%), and amorphous dioxide. Since it is composed of silicon (weight ratio: about 3%) and the theoretical concentration of nitrogen and phosphorus is 12.8% to 18.1% of nitrogen and 9.7% to 12.0% of phosphorus, powder fire extinguishing agent waste Contains a large amount of nitrogen and phosphorus among nitrogen, phosphorus and potassium, which are the three major elements of fertilizer, and can be used as fertilizer. Then, the process proceeds to S2.
Ｓ２において、アルコール噴霧工程が実施される。このアルコール噴霧工程では、粉末消火薬剤廃棄物にアルコール水溶液が噴霧される。具体的には、粉末消火薬剤廃棄物にアルコール水溶液としてのメタノール水溶液（アルコール濃度略５０％（メチルアルコールと水をそれぞれ略５０％の比率で混合））が噴霧される。より具体的には、まず攪拌器内に粉末消火薬剤廃棄物が投入され、噴霧手段（たとえば、噴霧器など）を用いて、その攪拌器内の粉末消火薬剤廃棄物にメタノール水溶液（粉末消火薬剤廃棄物の８％重量分）が噴霧される。なお、本実施形態では、アルコール水溶液として安価なメタノール水溶液を用いたが、これに限らず、変性アルコール（エチルアルコールに変性剤（メタノールなど）を加えたもの）など他のアルコール水溶液を用いてもよい。また、本実施形態では、アルコール濃度略５０％のメタノール水溶液を用いたが、これに限らず、メチルアルコールと水を他の混合比率で混合させたメタノール水溶液を用いてもよい。さらに、本実施形態では、噴霧されるメタノール水溶液の量を粉末消火薬剤廃棄物の８％重量分としたが、これに限定されず、粉末消火薬剤廃棄物の６％〜１０％（好ましくは、８％〜１０％）などの６％以上（好ましくは７％以上（より好ましくは８パーセント以上））重量分としてもよい。そして、Ｓ３に進む。 In S2, an alcohol spraying step is performed. In this alcohol spraying step, an aqueous alcohol solution is sprayed on the powdered fire extinguishing agent waste. Specifically, a methanol aqueous solution (alcohol concentration approximately 50% (methyl alcohol and water are mixed at a ratio of approximately 50% each)) as an aqueous alcohol solution is sprayed on the powder fire extinguishing chemical waste. More specifically, the powdered fire extinguishing agent waste is first introduced into the stirrer, and the aqueous methanol solution (powder fire extinguishing agent waste) is added to the powdered fire extinguishing agent waste in the stirrer using a spraying means (for example, a sprayer). 8% by weight). In the present embodiment, an inexpensive methanol aqueous solution is used as the alcohol aqueous solution. However, the present invention is not limited to this, and other alcohol aqueous solutions such as denatured alcohol (ethyl alcohol to which a denaturant (methanol or the like) is added) may be used. Good. In this embodiment, an aqueous methanol solution having an alcohol concentration of about 50% is used. However, the present invention is not limited to this, and an aqueous methanol solution in which methyl alcohol and water are mixed at another mixing ratio may be used. Further, in the present embodiment, the amount of the methanol aqueous solution to be sprayed is set to 8% by weight of the powder fire extinguishing agent waste, but is not limited thereto, and 6% to 10% of the powder fire extinguishing agent waste (preferably, 6% or more (preferably 7% or more (more preferably 8% or more)) such as 8% to 10% by weight. Then, the process proceeds to S3.
Ｓ３において、攪拌工程が実施される。この攪拌工程では、アルコール噴霧工程（Ｓ２）により噴霧されたアルコール水溶液と粉末消火薬剤廃棄物とを攪拌し、粉末消火薬剤廃棄物表面のシリコンコートが除去される。具体的には、攪拌器を回転させてアルコール噴霧工程により噴霧されたメタノール水溶液と粉末消火薬剤廃棄物を攪拌させる。なお、上述したアルコール噴霧工程（Ｓ２）として、攪拌器を回転させながらメタノール水溶液を粉末消火薬剤廃棄物に噴霧させてもよい。 In S3, a stirring step is performed. In this stirring step, the alcohol aqueous solution sprayed in the alcohol spraying step (S2) and the powdered fire extinguishing agent waste are stirred to remove the silicon coat on the surface of the powdered extinguishing agent waste. Specifically, the agitator is rotated to agitate the methanol aqueous solution and the powdered fire extinguishing agent waste sprayed in the alcohol spraying step. In the alcohol spraying step (S2) described above, an aqueous methanol solution may be sprayed on the powdered fire extinguishing agent waste while rotating the stirrer.
このように、噴霧されたメタノール水溶液と粉末消火薬剤廃棄物とが攪拌され、粉末消火薬剤廃棄物表面のシリコンコートがメタノール水溶液で分解され、シリコンコートを除去することができる。また、メタノール水溶液（アルコール水溶液）を用いているので、人体へ悪影響を与えることなく取り扱うことができる。さらに、粉末消火薬剤廃棄物にメタノール水溶液を噴霧し、メタノール水溶液と粉末消火薬剤廃棄物とを攪拌することにより、万遍なくメタノール水溶液が粉末消火薬剤廃棄物に混ざり、ダマ（丸い塊）の発生を極めて少なくすることができる。そして、Ｓ４に進む。 Thus, the sprayed methanol aqueous solution and the powdered fire extinguishing agent waste are stirred, and the silicon coat on the surface of the powdered fire extinguishing agent waste is decomposed by the methanol aqueous solution, and the silicon coat can be removed. Further, since an aqueous methanol solution (aqueous alcohol solution) is used, it can be handled without adversely affecting the human body. Further, by spraying the aqueous methanol solution on the powder fire extinguishing agent waste and stirring the aqueous methanol solution and the powder extinguishing agent waste, the aqueous methanol solution is uniformly mixed with the powder fire extinguishing agent waste, generating lumps (rounds). Can be extremely reduced. Then, the process proceeds to S4.
Ｓ４において、送風工程が実施される。この送風工程では、攪拌されている粉末消火薬剤廃棄物が飛散されなくなった後に、送風手段（扇風機など）を用いてメタノール水溶液と粉末消火薬剤廃棄物の混合物に送風して、混合物中のメタノールを蒸発させる。なお、本実施形態では、送風工程を別個の工程としたが、これに限らず、送風工程を攪拌工程の一部としてもよい。そして、Ｓ５に進む。 In S4, a blowing process is performed. In this blowing step, after the stirred powder fire extinguishing agent waste is no longer scattered, air is blown to a mixture of the aqueous methanol solution and the powder fire extinguishing agent waste using a blowing means (such as an electric fan) to remove the methanol in the mixture. Allow to evaporate. In the present embodiment, the blowing step is a separate step. However, the present invention is not limited to this, and the blowing step may be a part of the stirring step. Then, the process proceeds to S5.
このように、攪拌されている粉末消火薬剤廃棄物が飛散されなくなった後に、送風手段によりメタノール水溶液と粉末消火薬剤廃棄物の混合物に送風して、混合物中のメタノールを蒸発させるので、メタノールの嫌な臭いを極めて少なくすることができる。なお、送風工程は粉末消火薬剤廃棄物液体肥料生成方法の任意の工程であり、メタノールの嫌な臭いを極めて少なくする必要がない場合は粉末消火薬剤廃棄物液体肥料生成方法に含めなくてもよい。 In this way, after the stirred powder fire extinguishing agent waste is no longer scattered, the mixture is blown to the mixture of the aqueous methanol solution and the powdered fire extinguishing agent waste by the blowing means to evaporate the methanol in the mixture. Odor can be extremely reduced. Note that the air blowing step is an optional step of the method for producing a powder fire extinguishing chemical waste liquid fertilizer, and may not be included in the method for producing a powder fire extinguishing chemical waste liquid fertilizer when it is not necessary to extremely reduce the unpleasant odor of methanol. .
Ｓ５において、濾過工程が実施される。この濾過工程では、攪拌工程（Ｓ３）によりシリコンコートが除去された粉末消火薬剤廃棄物とアルコール水溶液の混合物を濾過し、不純物が取り除かれる。具体的には、濾斗の上部に濾紙を載せて、シリコンコートが除去された粉末消火薬剤廃棄物とアルコール水溶液の混合物を逆三角すい状の濾紙の上部から濾紙内に挿入させる。これにより、細かい孔がたくさんあいた濾紙を介して、濾紙の孔より小さい粒子のコンコートが除去された粉末消火薬剤廃棄物とアルコール水溶液の混合物の成分（液体）が濾紙を通過し、容器内に挿入される。これにより、シリコンコートが除去された粉末消火薬剤廃棄物とアルコール水溶液の混合物が濾過されるので、不純物が取り除かれた透明な液体肥料を生成することができる。この濾紙を介して容器内に挿入された液体は、粉末消火薬剤廃棄物から抽出された窒素やリンが多く含有することから、液体肥料として利用ことができる。なお、本実施形態では、濾斗の上部に濾紙を載せて濾過したが、必ずしも濾斗の上部に濾紙を載せて濾過する必要はなく、コンコートが除去された粉末消火薬剤廃棄物とアルコール水溶液の混合物を濾過するものであれば、他の方法であってもよい。 In S5, a filtration step is performed. In this filtration step, the mixture of the powdered fire extinguishing agent waste and the aqueous alcohol solution from which the silicon coat has been removed in the stirring step (S3) is filtered to remove impurities. Specifically, the filter paper is placed on the upper part of the funnel, and the mixture of the powdered fire extinguishing agent waste and the alcohol aqueous solution from which the silicon coat has been removed is inserted into the filter paper from the upper part of the inverted triangular cone-shaped filter paper. As a result, the component (liquid) of the mixture of the powdered fire extinguishing agent waste and the aqueous alcohol solution from which the concoat of particles smaller than the pores of the filter paper has been removed passes through the filter paper through the filter paper with many fine pores, and enters the container. Inserted. As a result, the mixture of the powdered fire extinguishing agent waste and the alcohol aqueous solution from which the silicon coat has been removed is filtered, so that a transparent liquid fertilizer from which impurities have been removed can be produced. The liquid inserted into the container through the filter paper can be used as a liquid fertilizer because it contains a large amount of nitrogen and phosphorus extracted from the powdered fire extinguishing agent waste. In this embodiment, the filter paper is placed on the upper part of the funnel and the filtration is performed.However, it is not always necessary to place the filter paper on the upper part of the funnel and the filtration is carried out. Other methods may be used as long as the mixture is filtered.
以上のように、濾過工程により抽出された液体肥料は透明であるため、その液体肥料が農業従事者等に使用される場合でも何ら問題なく使用される。また、液体肥料は液体であるため、農業従事者等により実際に使用される場面でも、肥料が風に飛散されることなく、容易かつ適切に肥料を散布することができる。さらに、液体肥料は液体であるため、肥料加工物を生成させる場合にも、肥料が飛散せず、容易に肥料加工物を生成することができる。 As described above, since the liquid fertilizer extracted in the filtration step is transparent, it can be used without any problem even when the liquid fertilizer is used by farmers and the like. Further, since the liquid fertilizer is a liquid, the fertilizer can be easily and appropriately applied without being scattered by the wind even in a situation where the fertilizer is actually used by a farmer or the like. Further, since the liquid fertilizer is a liquid, even when a fertilizer processed product is generated, the fertilizer does not scatter and the fertilized processed product can be easily generated.
次に、本発明の粉末消火薬剤廃棄物液体肥料生成方法の第２の実施形態について図面を参照にしながら説明する。図２は、本発明の第２の実施形態における粉末消火薬剤廃棄物液体肥料生成方法のフローチャートである。ここで、第２の実施形態の肥料作成工程と第１の実施形態の肥料作成工程とは、第１の実施形態では噴霧器を用いてメタノール水溶液を粉末消火薬剤廃棄物に噴霧させたが、第２の実施形態ではメタノール水溶液を粉末消火薬剤廃棄物に投入させる点について異なる。その他については、第１の実施形態と同様であるので説明は省略する。 Next, a second embodiment of the powder fire extinguishing agent waste liquid fertilizer production method of the present invention will be described with reference to the drawings. FIG. 2 is a flowchart of a method for producing a powder fire extinguishing chemical waste liquid fertilizer according to the second embodiment of the present invention. Here, the fertilizer preparation step of the second embodiment and the fertilizer preparation step of the first embodiment are different from the first embodiment in that the methanol aqueous solution is sprayed on the powder fire extinguishing agent waste using a sprayer in the first embodiment. The second embodiment is different from the first embodiment in that an aqueous methanol solution is introduced into the powder fire extinguishing agent waste. Others are the same as in the first embodiment, and a description thereof will be omitted.
Ｓ１１の粉末消化薬剤廃棄物分別工程は、第１の実施形態（Ｓ１の粉末消化薬剤廃棄物分別工程）と同様であるので、説明は省略する。 The powder digestive medicine waste sorting step of S11 is the same as that of the first embodiment (the powder digestive medicine waste sorting step of S1), and thus the description is omitted.
Ｓ１２において、アルコール投入工程が実施される。このアルコール投入工程では、粉末消火薬剤廃棄物にアルコール水溶液としてのメタノール水溶液（アルコール濃度略５０％（メチルアルコールと水をそれぞれ略５０％の比率で混合））が投入される。具体的には、まず攪拌器内に粉末消火薬剤廃棄物が投入され、その攪拌器内の粉末消火薬剤廃棄物にメタノール水溶液が投入される。なお、本実施形態では、攪拌器内の粉末消火薬剤廃棄物にメタノール水溶液を投入させたが、これに限らず、アルコール投入工程として、攪拌器内に粉末消火薬剤廃棄物を投入して、その攪拌器を回転させながらメタノール水溶液を粉末消火薬剤廃棄物に投入させてもよい。その他については、第１の実施形態と同様であるので、説明は省略する。そして、Ｓ１３に進む。 In S12, an alcohol charging step is performed. In this alcohol charging step, a methanol aqueous solution (alcohol concentration approximately 50% (methyl alcohol and water are mixed at a ratio of approximately 50% each)) as an alcohol aqueous solution is injected into the powder fire extinguishing agent waste. Specifically, first, a powder fire extinguishing agent waste is charged into a stirrer, and a methanol aqueous solution is charged into the powder fire extinguishing agent waste in the stirrer. In the present embodiment, the aqueous methanol solution was injected into the powder fire extinguishing agent waste in the stirrer.However, the present invention is not limited to this. The aqueous methanol solution may be charged into the powdered fire extinguishing agent waste while rotating the stirrer. The rest is the same as in the first embodiment, and a description thereof will be omitted. Then, the process proceeds to S13.
Ｓ１３において、攪拌工程が実施される。この攪拌工程では、アルコール投入工程（Ｓ１２）により投入されたメタノール水溶液（アルコール水溶液）と粉末消火薬剤廃棄物が攪拌される。具体的には、攪拌器を回転させてアルコール投入工程により投入されたメタノール水溶液と粉末消火薬剤廃棄物を攪拌させる。 In S13, a stirring step is performed. In this stirring step, the aqueous methanol solution (aqueous alcohol solution) and the powdered fire extinguishing agent waste that have been input in the alcohol input step (S12) are stirred. Specifically, the agitator is rotated to agitate the aqueous methanol solution and the powdered fire extinguishing agent waste charged in the alcohol charging step.
このように、投入されたメタノール水溶液と粉末消火薬剤廃棄物とが攪拌され、粉末消火薬剤廃棄物表面のシリコンコートがメタノール水溶液で分解され、シリコンコートを除去することができる。また、粉末消火薬剤廃棄物にメタノール水溶液を噴霧するアルコール噴霧工程を用いると、粉末消火薬剤廃棄物にメタノール水溶液を噴霧するための工程時間が必要となるが、アルコール投入工程により粉末消火薬剤廃棄物にメタノール水溶液が投入されるので、粉末消火薬剤廃棄物にメタノール水溶液を噴霧する時間を省略でき、粉末消火薬剤廃棄物の親水化処理時間をさらに短縮することができる。そして、Ｓ１４に進む。 In this way, the supplied methanol aqueous solution and the powdered fire extinguishing agent waste are stirred, and the silicon coat on the surface of the powdered fire extinguishing agent waste is decomposed with the methanol aqueous solution, and the silicon coat can be removed. In addition, if an alcohol spraying step of spraying an aqueous methanol solution on the powder fire extinguishing agent waste is used, a process time for spraying the aqueous methanol solution on the powder fire extinguishing agent waste is required. Since the aqueous methanol solution is introduced into the wastewater, the time for spraying the aqueous methanol solution onto the powdered fire extinguishing agent waste can be omitted, and the time required for hydrophilizing the powdered fire extinguishing agent waste can be further reduced. Then, the process proceeds to S14.
Ｓ１４の送風工程は、第１の実施形態（Ｓ４の送風工程）と同様であるので、説明は省略する。 Since the air blowing step of S14 is the same as that of the first embodiment (the air blowing step of S4), the description is omitted.
Ｓ１５の濾過工程は、第１の実施形態（Ｓ５の濾過工程）と同様であるので、説明は省略する。 Since the filtration step of S15 is the same as that of the first embodiment (the filtration step of S5), the description is omitted.
以上のように、第２実施形態においても、第１実施形態と同様、濾過工程により抽出された液体肥料は透明であるため、その液体肥料が農業従事者等に使用される場合でも何ら問題なく使用される。また、液体肥料は液体であるため、農業従事者等により実際に使用される場面でも、肥料が風に飛散されることなく、容易かつ適切に肥料を散布することができる。さらに、液体肥料は液体であるため、肥料加工物を生成させる場合にも、肥料が飛散せず、容易に肥料加工物を生成することができる。 As described above, in the second embodiment, as in the first embodiment, the liquid fertilizer extracted in the filtration step is transparent, so that there is no problem even when the liquid fertilizer is used by farmers and the like. used. Further, since the liquid fertilizer is a liquid, the fertilizer can be easily and appropriately applied without being scattered by the wind even in a situation where the fertilizer is actually used by a farmer or the like. Further, since the liquid fertilizer is a liquid, even when a fertilizer processed product is generated, the fertilizer does not scatter and the fertilized processed product can be easily generated.
