Abstract
Description
本発明は、汚染除去作業を実施した範囲を可視化する方法に関する。 The present invention relates to a method for visualizing an area in which a decontamination operation has been performed.
放射性物質や残留性有機汚染物質（ＰＯＰｓ）に汚染された機器、建屋などの除染作業は、水や洗浄剤（中性洗剤や有機溶剤等）などの洗浄用液体を布等の拭き取り用資材に浸透させて汚染物質を拭き取るか、噴射装置を用いて洗浄用液体を汚染箇所に噴射して汚染物質を洗浄除去するのが一般的である。 For decontamination work of equipment and buildings contaminated with radioactive substances and persistent organic pollutants (POPs), materials for cleaning such as water and cleaning liquids such as detergents (neutral detergents and organic solvents) are wiped off with cloth. In general, contaminants are wiped off by infiltration into the surface, or a cleaning liquid is sprayed onto a contaminated site using a spraying device to wash and remove the contaminants.
放射性物質や残留性有機汚染物質は、目視によりその存在を確認することが困難である。また、汚染物質を洗浄除去する洗浄用液体も汚染除去作業後に蒸発する。そのため、汚染除去作業未実施箇所が発生したり、汚染除去作業が重複したりするおそれがある。例えば、ＰＣＢ汚染物の場合、汚染除去作業を適切に実施しないと、ＰＣＢの蒸散によって周辺環境が汚染され健康被害を招くことになるが、汚染除去作業が適切になされたかどうか確認することは困難である。 It is difficult to visually confirm the presence of radioactive substances and persistent organic pollutants. Further, the cleaning liquid for cleaning and removing the contaminants also evaporates after the decontamination operation. Therefore, there is a possibility that a part where the decontamination operation has not been performed may occur or the decontamination operation may be duplicated. For example, in the case of PCB contaminants, if the decontamination work is not performed properly, the evaporation of the PCB will contaminate the surrounding environment and cause health damage, but it is difficult to confirm whether the decontamination work has been performed properly. It is.
他方、特許文献１には、被測定物表面の探傷領域に蛍光体を付加し、該領域に紫外線等の放射線を照射して欠陥部位に侵入した蛍光体を発光させることにより、被測定物表面の欠陥を検出する方法が開示されている。しかし、金属等の部分的欠陥の検出を目的としており、上記課題を解決するものではない。
また、特許文献２には、タバコヤニ汚れに紫外線を照射し、タバコヤニ自体の発光特性によりタバコヤニ汚れを可視化し、効率的に除去する方法が開示されている。しかし、汚染物質が紫外線の照射で発光しない場合には汚染除去には適用できないという問題がある。
On the other hand,
Further,
本発明はかかる事情に鑑みてなされたもので、汚染除去実施範囲を簡易な手段を用いて可視化することにより、汚染除去作業未実施箇所の発生や汚染除去作業の重複を防止することを目的とする。 The present invention has been made in view of such circumstances, and has an object to prevent the occurrence of a non-contamination operation-unexecuted portion and the repetition of the contamination removal operation by visualizing the decontamination execution range using simple means. I do.
上記目的を達成するため、本発明は、洗浄用液体を用いて汚染除去箇所（除染箇所）から汚染物質を洗浄除去する汚染除去作業において、汚染除去作業を実施した範囲に蛍光体を付加し、汚染除去作業終了後に汚染除去箇所に紫外線を照射して前記蛍光体を発光させることにより、汚染除去作業を実施した範囲を可視化することを特徴としている。 In order to achieve the above object, the present invention provides a decontamination operation for cleaning and removing contaminants from a decontamination point (decontamination point) using a cleaning liquid, wherein a phosphor is added to a range in which the decontamination operation is performed. After the decontamination operation is completed, the area where the decontamination operation is performed is visualized by irradiating ultraviolet rays to the decontamination site to emit light from the phosphor.
本発明が対象とする汚染物質は、放射性物質又は残留性有機汚染物質（ＰＯＰｓ）である。残留性有機汚染物質は、環境中で分解されにくく、生物の体内に蓄積しやすいため、生態系に悪影響を及ぼす化学物質であり、ダイオキシン類やＰＣＢ（ポリ塩化ビフェニル）、ＤＤＴなどが挙げられる。 The pollutants targeted by the present invention are radioactive substances or persistent organic pollutants (POPs). Persistent organic pollutants are difficult to decompose in the environment and easily accumulate in living organisms. Therefore, they are chemical substances that adversely affect the ecosystem, and examples thereof include dioxins, PCB (polychlorinated biphenyl), and DDT.
本発明に係る汚染除去実施範囲の可視化方法では、前記蛍光体を前記洗浄用液体に事前に添加するか、もしくは前記洗浄用液体を含浸させた布類の拭き取り面に前記蛍光体を塗布し、汚染除去作業の際に、汚染除去作業を実施した範囲に前記蛍光体を付加してもよいし、あるいは、前記洗浄用液体を用いて汚染除去箇所の汚染除去作業を実施した後、汚染除去作業を実施した範囲に残留する前記洗浄用液体が蒸発する前に、前記蛍光体を塗布した布類で汚染除去作業を実施した範囲を拭くか、もしくは前記蛍光体を含む液状物を汚染除去作業を実施した範囲に噴霧してもよい。 In the method of visualizing the contamination removal operation range according to the present invention, the phosphor is added to the cleaning liquid in advance, or the phosphor is applied to a wiping surface of cloth impregnated with the cleaning liquid, During the decontamination operation, the phosphor may be added to the area where the decontamination operation has been performed, or the decontamination operation may be performed at the decontamination point using the cleaning liquid. Before evaporating the cleaning liquid remaining in the area where the cleaning was performed, wipe the area where the decontamination work was performed with the cloth coated with the phosphor, or perform the decontamination work on the liquid material containing the phosphor. It may be sprayed in the implemented range.
本発明では、汚染除去作業を実施した範囲に蛍光体を付加し、汚染除去箇所に紫外線を照射して蛍光体を発光させることにより、汚染除去作業を実施した範囲を可視化するので、汚染除去作業未実施箇所の発生や汚染除去作業の重複を防止することができる。 In the present invention, since the phosphor is added to the area where the decontamination work was performed, and the area where the decontamination work was performed is visualized by irradiating ultraviolet rays to the decontamination area and causing the phosphor to emit light. It is possible to prevent the occurrence of unexecuted portions and the duplication of the decontamination work.
続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態について説明し、本発明の理解に供する。 Next, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention.
［第１の実施の形態に係る汚染除去実施範囲の可視化方法］
本実施の形態に係る汚染除去実施範囲の可視化方法は、汚染物質に汚染された機器、建屋などの汚染除去作業に当たって、汚染除去作業を実施した範囲を可視化して認識できるようにする方法である。
[Visualization Method of Pollution Removal Execution Range According to First Embodiment]
The method for visualizing the decontamination execution range according to the present embodiment is a method for visualizing and recognizing the range in which the decontamination operation has been performed in the decontamination operation of equipment, buildings, and the like contaminated with contaminants. .
対象とする汚染物質は、放射性物質又は残留性有機汚染物質（ＰＯＰｓ）である。
図１に、本実施の形態に係る汚染除去実施範囲の可視化方法の作業手順を示す。
The pollutants of interest are radioactive or persistent organic pollutants (POPs).
FIG. 1 shows an operation procedure of a method for visualizing a contamination removal execution range according to the present embodiment.
［第１ステップ］
汚染物質を洗浄除去する洗浄用液体に蛍光体を付加する（ＳＴ１１）。具体的には、蛍光体を洗浄用液体に事前に添加するか、もしくは洗浄用液体を含浸させた布類の拭き取り面に蛍光体を塗布する。
洗浄用液体には、炭化水素系洗浄剤（例えばＮＳクリーン（登録商標））や中性洗剤などを使用することができる。
また、蛍光体には、有機蛍光顔料などを使用することができる。洗浄用液体に対する蛍光体の割合は０．５〜２０．０質量％、好ましくは２．０〜７．０質量％とする。
蛍光体の濃度が０．５質量％未満であると、発光が不十分となる一方、蛍光体の濃度が２０．０質量％を超えると、洗浄用液体の洗浄効果が減殺される。
[First step]
A phosphor is added to the cleaning liquid for cleaning and removing contaminants (ST11). Specifically, the phosphor is added to the cleaning liquid in advance, or the phosphor is applied to a wiped surface of cloth impregnated with the cleaning liquid.
As the cleaning liquid, a hydrocarbon-based cleaning agent (for example, NS Clean (registered trademark)), a neutral detergent, or the like can be used.
Further, an organic fluorescent pigment or the like can be used for the phosphor. The ratio of the phosphor to the cleaning liquid is 0.5 to 20.0% by mass, preferably 2.0 to 7.0% by mass.
When the concentration of the phosphor is less than 0.5% by mass, light emission becomes insufficient. On the other hand, when the concentration of the phosphor exceeds 20.0% by mass, the cleaning effect of the cleaning liquid is reduced.
［第２ステップ］
洗浄用液体で汚染除去箇所を洗浄して、汚染除去箇所から汚染物質を除去する（ＳＴ１２）。この汚染除去作業の際に、汚染除去作業を実施した範囲に蛍光体が付加される。
[Second step]
The decontamination site is washed with the cleaning liquid to remove contaminants from the decontamination site (ST12). At the time of this decontamination work, a phosphor is added to the area where the decontamination work was performed.
［第３ステップ］
汚染除去箇所に紫外線を照射して蛍光体を発光させる（ＳＴ１３）。図２に、汚染除去箇所１０に紫外線１２を照射しているイメージ図を示す。本実施の形態では、紫外線源としてブラックライト１１を使用している。
汚染除去箇所１０に紫外線１２を照射することにより、汚染除去作業を実施した範囲に残存している発光体１３が発光し、汚染除去作業を実施した範囲が確認できる。
[Third step]
The phosphor is emitted by irradiating ultraviolet rays to the contamination removal portion (ST13). FIG. 2 shows an image diagram of irradiating the
By irradiating the
なお、汚染除去実施範囲を可視化する方法として、洗浄用液体に一般の塗料を付加し、汚染除去作業実施後に塗料を残留させる方法も考えられるが、一般の塗料が残存すると、作業後に著しく美感を損ねることになる。また、汚染除去箇所がプラント機器の場合、機器には機器名称の記載、配管には流体名称の記載や流体識別色が塗布されている場合が多いので、その識別を妨げることになる。一方、洗浄用液体に蛍光体を付加した場合、作業後に著しく美感を損ねることもなく、たとえ拭き取る事態が発生したとしても、拭き取りは極めて容易である。 In addition, as a method of visualizing the decontamination execution range, a method in which a general paint is added to the cleaning liquid and the paint is left after the decontamination work is performed, but if the general paint remains, the appearance is significantly improved after the work. It will hurt. When the decontamination site is a plant device, the device name is often described on the device and the fluid name is described or the fluid identification color is applied on the piping in many cases. On the other hand, when the phosphor is added to the cleaning liquid, the wiping is extremely easy even if the wiping occurs, without significantly impairing the beauty after the operation.
［第２の実施の形態に係る汚染除去実施範囲の可視化方法］
本実施の形態に係る汚染除去実施範囲の可視化方法の作業手順を図３に示す。
本実施の形態では、先ず最初に、蛍光体を含まない洗浄用液体を用いて汚染除去箇所の洗浄除去作業を行う（ＳＴ２１）。
次いで、汚染除去実施範囲に蛍光体を付加する（ＳＴ２２）。具体的には、汚染除去実施範囲（汚染除去作業を実施した範囲）に残留する洗浄用液体が蒸発する前に、蛍光体を塗布した布類で汚染除去実施範囲を拭くか、もしくは蛍光体を含む液状物を汚染除去実施範囲に噴霧する。
その後、汚染除去箇所に紫外線を照射して蛍光体を発光させる（ＳＴ２３）。
[Visualization Method of Pollution Removal Execution Range According to Second Embodiment]
FIG. 3 shows an operation procedure of the visualization method of the contamination removal execution range according to the present embodiment.
In the present embodiment, first, a cleaning and removing operation of a contamination removing portion is performed using a cleaning liquid containing no phosphor (ST21).
Next, a phosphor is added to the contamination removal execution range (ST22). Specifically, before the cleaning liquid remaining in the decontamination execution range (the range in which the decontamination operation was performed) evaporates, wipe the decontamination execution range with a cloth coated with a phosphor, or remove the phosphor. The contained liquid material is sprayed on the decontamination area.
After that, the phosphor is irradiated by irradiating ultraviolet rays to the contamination removal portion (ST23).
以上、本発明の実施の形態について説明してきたが、本発明は何ら上記した実施の形態に記載の構成に限定されるものではなく、特許請求の範囲に記載されている事項の範囲内で考えられるその他の実施の形態や変形例も含むものである。 As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the configurations described in the above-described embodiments, and is considered within the scope of the matters described in the claims. It also includes other embodiments and modified examples.
