Description
本発明は、解体建築材の処理方法に関し、詳しくは、有害物質が付着した解体建築材の処理方法に関する。 The present invention relates to a method for treating demolished building materials, and more specifically, to a method for treating demolished building materials to which harmful substances have been attached.
従来、この種の解体建築材の処理方法としては、ＰＣＢ汚染物の表面に２層以上の積層構造を有する塗膜を形成するものが提案されている（例えば、特許文献１参照）。この処理方法では、ＰＣＢ汚染物に接する第１層を、塗布部材を汚染物表面に接触させる塗布方法で形成している。 A conventional method for treating this type of demolished building material has been proposed in which a coating film having a laminated structure of two or more layers is formed on the surface of the PCB-contaminated material (see, for example, Patent Document 1). In this treatment method, the first layer that comes into contact with the PCB-contaminated material is formed by a coating method in which a coating member is brought into contact with the surface of the contaminated material.
しかしながら、上述の処理方法では、解体建築材の表面に高濃度に有害物質が付着していると、塗膜に破損が生じたときには有害物質による環境などへの汚染が生じる場合がある。このことは３層以上の積層構造としても同様である。 However, with the above-mentioned treatment method, if there is a high concentration of harmful substances on the surface of the demolished building materials, damage to the coating may result in the harmful substances contaminating the environment. This also applies to laminated structures of three or more layers.
本発明の解体建築材の処理方法は、塗膜に破損が生じても有害物質による環境などへの汚染を抑制することを主目的とする。 The main purpose of the method for treating demolished building materials of the present invention is to prevent environmental pollution caused by harmful substances even if the coating is damaged.
本発明の解体建築材の処理方法は、上述の主目的を達成するために以下の手段を採った。 The method for processing demolished building materials of the present invention employs the following measures to achieve the above-mentioned main objective.
本発明の解体建築材の処理方法は、
有害物質が付着した解体建築材の処理方法であって、
負圧に調整した第１所定空間内で前記解体建築材に対してブラスト処理を施すブラスト処理工程と、
負圧に調整した第２所定空間内で前記ブラスト処理を施した前記解体建築材の表面に樹脂系塗料を塗布する塗料塗布工程と、
とを有することを特徴とする。
The method for processing dismantled building materials of the present invention comprises the steps of:
A method for treating demolished building materials to which harmful substances have been attached, comprising the steps of:
a blasting process for performing a blasting process on the dismantled building materials in a first predetermined space adjusted to a negative pressure;
A paint application process for applying a resin-based paint to the surface of the dismantled building material that has been subjected to the blast treatment in a second predetermined space adjusted to a negative pressure;
The present invention is characterized by having the following features.
本発明の解体建築材の処理方法では、負圧に調整した第１所定空間内で解体建築材に対してブラスト処理を施し、その後、負圧に調整した第２所定空間内でブラスト処理を施した解体建築材の表面に樹脂系塗料を塗布する。解体建築材に対してブラスト処理を施すことにより、処理後の解体建築材の表面における有害物質の濃度を極めて低くすることができる。この結果、解体建築材に塗布した樹脂系塗料の塗膜に破損が生じても、有害物質による環境などへの汚染を抑制することができる。なお、ブラスト処理を負圧に調整した第１所定空間内で行なうのは、ブラスト処理による有害物質が付着した粉塵等が第１所定空間外に飛散するのを抑止するためである。樹脂系塗料の塗布を負圧に調整した第２所定空間内で行なうのは、樹脂系塗料を塗布する際に解体建築材の表面に僅かに付着している粉塵などが第２所定空間外に飛散するのを抑止するためである。 In the method for processing dismantled building materials of the present invention, the dismantled building materials are blasted in a first predetermined space adjusted to a negative pressure, and then a resin-based paint is applied to the surface of the dismantled building materials that have been blasted in a second predetermined space adjusted to a negative pressure. By blasting the dismantled building materials, the concentration of harmful substances on the surface of the dismantled building materials after processing can be extremely low. As a result, even if the coating of the resin-based paint applied to the dismantled building materials is damaged, pollution of the environment by harmful substances can be suppressed. The blasting is performed in the first predetermined space adjusted to a negative pressure in order to prevent dust and the like to which harmful substances are attached due to the blasting from scattering outside the first predetermined space. The application of the resin-based paint is performed in the second predetermined space adjusted to a negative pressure in order to prevent dust and the like that is slightly attached to the surface of the dismantled building materials from scattering outside the second predetermined space when the resin-based paint is applied.
本発明の解体建築材の処理方法において、前記ブラスト工程と前記塗料塗布工程との間に前記第２所定空間内で前記ブラスト処理を施した前記解体建築材の表面を洗浄する洗浄工程を有するものとしてもよい。こうすれば、解体建築材の表面にブラスト処理の際に付着する粉塵（有害物質を含む）を洗い落とすことができる。 The method for treating dismantled building materials of the present invention may include a cleaning process between the blasting process and the paint application process, in which the surface of the dismantled building materials that have been subjected to the blasting process in the second predetermined space is cleaned. In this way, dust (including harmful substances) that adheres to the surface of the dismantled building materials during the blasting process can be washed off.
本発明の解体建築材の処理方法において、前記有害物質はポリ塩化ビフェニルであり、前記樹脂系塗料は水系ビニル樹脂塗料であるものとしてもよい。 In the method for treating demolished building materials of the present invention, the harmful substance may be polychlorinated biphenyl, and the resin-based paint may be a water-based vinyl resin paint.
本発明の解体建築材の処理方法および上述した態様（有害物質がポリ塩化ビフェニルである態様）の解体建築材の処理方法において、前記解体建築材は鋼材であり、前記樹脂系塗料を塗布した前記解体建築材を溶融する溶融工程を有するものとしてもよい。解体建築材の溶融の際に樹脂系塗料に閉じ込められた僅かな有害物質等も分解するから、溶融した鋼材をリユースすることができる。 In the method for treating dismantled building materials of the present invention and the above-mentioned embodiment (embodiment in which the harmful substance is polychlorinated biphenyl), the dismantled building materials may be steel materials, and the method may include a melting step of melting the dismantled building materials coated with the resin-based paint. When the dismantled building materials are melted, even traces of harmful substances trapped in the resin-based paint are decomposed, and the melted steel materials can be reused.
本発明の解体建築材の処理方法および上述の全ての態様（有害物質がポリ塩化ビフェニルである態様と解体建築材が鋼材である態様）において、前記ブラスト処理は、研削材としてスチールグリットを用いた循環式ブラスト工法を用いる処理であるものとしてもよい。 In the method for treating demolished building materials of the present invention and in all of the above-mentioned aspects (the aspect in which the hazardous substance is polychlorinated biphenyls and the aspect in which the demolished building materials are steel), the blasting process may be a process using a circulating blasting method using steel grit as an abrasive.
次に、本発明の実施形態について説明する。図１は、本発明の実施形態としての解体建築材の処理方法の一例の工程をブロックを用いて模式的に示すブロック図であり、図２は、実施形態の解体建築材の処理方法の一例の工程を示す工程図である。 Next, an embodiment of the present invention will be described. FIG. 1 is a block diagram that shows the steps of an example of a method for processing dismantled building materials as an embodiment of the present invention, and FIG. 2 is a process diagram that shows the steps of an example of a method for processing dismantled building materials as an embodiment.
実施形態の解体建築材は、ＰＣＢ処理施設や廃棄物焼却施設などの大規模施設の解体工事によって生じる有害物質等が付着した建築材であり、リユースが可能な鋼材や、廃棄されるコンクリート廃材などが相当する。以下では、解体建築材として主にリユースが可能な鋼材を例として説明する。 The demolished building materials in this embodiment are building materials contaminated with hazardous substances and the like that are generated during the demolition of large-scale facilities such as PCB processing facilities and waste incineration facilities, and correspond to reusable steel materials and discarded concrete waste materials. In the following, we will mainly use reusable steel materials as an example of demolished building materials.
実施形態の解体建築材の処理方法は、まず、解体建築材を負圧に調整した第１処理室に搬入する（工程Ｓ１００）。第１処理室としては、粉塵や有害物質の飛散や雨水による地下水汚染を防止するために解体対象の建屋を完全に覆うように構築される外周構造物がある場合には、この外周構造物自体を用いるものとしたり、この外周構造物の内側に設置するものとしてもよい。外周構造物自体を第１処理室として用いる場合には、解体建築材の第１処理室への搬入は不要な工程となる。第１処理室は、図１に示すように、集塵機により集塵されることにより負圧に調整されている。。 In the embodiment of the method for processing demolished building materials, the demolished building materials are first carried into a first processing chamber adjusted to a negative pressure (step S100). When there is an outer peripheral structure constructed to completely cover the building to be demolished in order to prevent the scattering of dust and harmful substances and groundwater contamination by rainwater, the outer peripheral structure itself may be used as the first processing chamber, or a processing chamber may be installed inside the outer peripheral structure. When the outer peripheral structure itself is used as the first processing chamber, carrying the demolished building materials into the first processing chamber is an unnecessary step. As shown in FIG. 1, the first processing chamber is adjusted to a negative pressure by collecting dust with a dust collector. .
続いて、第１処理室内でブラスト処理により解体建築材の表面を研削する（工程Ｓ１１０）。ブラスト処理は、小さな粒や粉状の物を噴射して対象物に衝突させることにより、対象物の表面を研削する処理である。本実施形態では、ブラスト処理として、例えば研削材としてスチールグリットを用いた循環式ブラスト工法を用いた。ブラスト処理を負圧に調整した第１処理室内で行なうのは、ブラスト処理による有害物質が付着した粉塵等が第１所定空間外に飛散するのを抑止するためである。 Then, the surface of the demolished building material is ground by blasting in the first treatment chamber (step S110). Blasting is a process in which small particles or powder are sprayed onto the object and collided with it to grind the surface of the object. In this embodiment, a circulating blasting method using steel grit as the abrasive material is used as the blasting. The blasting is performed in the first treatment chamber adjusted to negative pressure in order to prevent dust and other particles containing harmful substances from the blasting from scattering outside the first specified space.
次に、ブラスト処理を施した解体建築材を負圧に調整した第２処理室に搬送する（工程Ｓ１２０）。第２処理室は、第１処理室とは個別に設置してもよいが第１処理室の一画に設置するものとしてもよい。第２処理室は、第１処理室と同様に集塵機により集塵されることにより負圧に調整されている。 Next, the demolished building materials that have been subjected to the blasting process are transported to a second treatment chamber that is adjusted to a negative pressure (step S120). The second treatment chamber may be installed separately from the first treatment chamber, or may be installed in a section of the first treatment chamber. The second treatment chamber is adjusted to a negative pressure by collecting dust with a dust collector, just like the first treatment chamber.
第２処理室では、まず、ブラスト処理を施した解体建築材の表面を洗浄する（工程Ｓ１３０）。洗浄は、水や周知の洗浄液などを用いることができる。こうした洗浄により、ブラスト処理によって解体建築材の表面に付着した粉塵（有害物質を含む）を洗い落とすことができる。 In the second treatment chamber, first, the surface of the demolished building material that has been subjected to the blasting process is cleaned (step S130). For cleaning, water or a well-known cleaning solution can be used. This cleaning can wash away dust (including harmful substances) that has adhered to the surface of the demolished building material by the blasting process.
第２処理室では、次に、表面を洗浄した解体建築材の表面に樹脂系塗料を塗布する（工程Ｓ１４０）。樹脂系塗料としては、フェノール樹脂やアルキド樹脂，メラミン樹脂，エポキシ樹脂，ウレタン樹脂，シリコン樹脂，塩化ビニル樹脂，酢酸ビニル樹脂，フッ素樹脂，セルロースなどを用いることができ、水系ビニル樹脂塗料が好適である。例えば、米国・カーボライン社が原子炉内の除染用に開発した水系ビニル樹脂塗料（ALARA 1146 CAVITY DECON）を用いることができる。この水系ビニル樹脂塗料は、放射性物質で汚染された表面に塗装すると、塗料が被塗面の微小な空間に染み込み、汚染物質と吸着・結合して塗膜中に汚染物質を閉じ込める。本実施形態では、樹脂系塗料として水系ビニル樹脂塗料（ALARA 1146 CAVITY DECON：以下「Ｃ剤」と称する。）を塗装ローラーを用いて塗布した。なお、解体建築材の洗浄や樹脂系塗料の塗布を負圧に調整した第２処理室で行なうのは、洗浄の際や樹脂系塗料を塗布する際に解体建築材の表面に僅かに付着している粉塵（有害物質を含む）などが第２処理室外に飛散するのを抑止するためである。 In the second treatment chamber, a resin-based paint is then applied to the surface of the washed demolished building material (step S140). As the resin-based paint, phenolic resin, alkyd resin, melamine resin, epoxy resin, urethane resin, silicone resin, polyvinyl chloride resin, polyvinyl acetate resin, fluororesin, cellulose, etc. can be used, and water-based vinyl resin paint is preferable. For example, a water-based vinyl resin paint (ALARA 1146 CAVITY DECON) developed by Carboline, Inc., USA, for decontamination inside nuclear reactors can be used. When this water-based vinyl resin paint is applied to a surface contaminated with radioactive materials, the paint penetrates into the minute spaces of the surface to be painted, adsorbs and binds to the contaminants, and traps the contaminants in the paint film. In this embodiment, a water-based vinyl resin paint (ALARA 1146 CAVITY DECON: hereinafter referred to as "agent C") is applied as the resin-based paint using a paint roller. The cleaning of the demolished building materials and the application of the resin-based paint are carried out in the second treatment chamber, which is adjusted to a negative pressure, in order to prevent dust (including harmful substances) that adheres to the surface of the demolished building materials in small amounts from scattering outside the second treatment chamber during cleaning or application of the resin-based paint.
樹脂系塗料が塗布された解体建築材は、第２処理室から搬出され（工程Ｓ１５０）、解体建築材が鋼材であるときには溶融処理により溶融されて鋼材としてリユースされ、廃棄しかできない材（コンクリート材など）は、産業廃棄物として埋め立て処理などにより廃棄される。解体建築材が溶融処理される場合は、樹脂系塗料やこの樹脂系塗料に閉じ込められた極僅かな有害物質は鋼材と共に溶融され、加熱分解等により無害化される。解体建築材が廃棄される場合、極僅かな有害物質は樹脂系塗料に閉じ込められているから、搬送の際や廃棄後でも環境を汚染するのを抑止することができる。 The demolished building materials coated with the resin-based paint are removed from the second treatment chamber (step S150). If the demolished building materials are steel, they are melted by melting treatment and reused as steel, whereas materials that can only be discarded (such as concrete) are disposed of as industrial waste by landfilling or other methods. When the demolished building materials are melted, the resin-based paint and the very small amounts of harmful substances trapped in this resin-based paint are melted together with the steel and rendered harmless by thermal decomposition or other methods. When the demolished building materials are discarded, the very small amounts of harmful substances are trapped in the resin-based paint, so environmental pollution can be prevented during transportation and after disposal.
以上説明した実施形態の解体建築材の処理方法では、ＰＣＢ処理施設や廃棄物焼却施設などの大規模施設の解体工事によって生じる有害物質等が付着した建築材（解体建築材）をブラスト処理を施すと共に、その後、ブラスト処理後の解体建築材の表面に樹脂系塗料を塗布する。ブラスト処理を施すことにより、処理後の解体建築材の表面における有害物質の濃度を極めて低くすることができる。また、ブラスト処理後の解体建築材の表面に樹脂系塗料を塗布することにより、ブラスト処理後の解体建築材の表面に極僅かに付着する有害物質を閉じ込めることができる。これらの結果、解体建築材に塗布した樹脂系塗料の塗膜に破損が生じても、有害物質による環境などへの汚染を抑制することができる。 In the embodiment of the method for processing demolished building materials described above, building materials (demolished building materials) to which harmful substances, etc., generated during the demolition of large-scale facilities such as PCB processing facilities and waste incineration facilities are attached are subjected to a blasting process, and then a resin-based paint is applied to the surface of the demolished building materials after the blasting process. By performing a blasting process, the concentration of harmful substances on the surface of the demolished building materials after the process can be extremely reduced. In addition, by applying a resin-based paint to the surface of the demolished building materials after the blasting process, it is possible to confine the extremely small amount of harmful substances that are attached to the surface of the demolished building materials after the blasting process. As a result, even if the coating of the resin-based paint applied to the demolished building materials is damaged, it is possible to suppress pollution of the environment by harmful substances.
実施形態の解体建築材の処理方法では、ブラスト処理された解体建築材の表面に樹脂系塗料を塗布する前にブラスト処理後の解体建築材を洗浄する。これにより、解体建築材の表面にブラスト処理の際に付着する粉塵（有害物質を含む）を洗い落とすことができる。 In the embodiment of the method for treating demolished building materials, the blasted demolished building materials are washed before a resin-based paint is applied to the surface of the blasted demolished building materials. This makes it possible to wash off dust (including harmful substances) that adheres to the surface of the demolished building materials during the blasting process.
実施形態の解体建築材の処理方法では、ブラスト処理された解体建築材の表面に樹脂系塗料を塗布する前にブラスト処理後の解体建築材を洗浄するものとした。しかし、こうした洗浄を行なうことなくブラスト処理された解体建築材の表面に樹脂系塗料を塗布するものとしても構わない。 In the embodiment of the method for treating dismantled building materials, the blasted dismantled building materials are washed before the resin-based paint is applied to the surface of the blasted dismantled building materials. However, the resin-based paint may be applied to the surface of the blasted dismantled building materials without washing.
