Description

本発明は、ポリ塩化ビフェニル(以下「PCB」という。)に汚染されたPCB汚染廃電気機器を洗浄する洗浄装置に関する。 The present invention relates to a cleaning apparatus for cleaning PCB-contaminated waste electrical equipment contaminated with polychlorinated biphenyl (hereinafter referred to as “PCB”).

従来から、トランス、コンデンサ、計器用変成器、リアクトル、放電コイル、OFケーブルなどのPCB汚染廃電気機器から、PCBを除去する方法が、種々提案されている。
特に、近年、酸化チタンとアパタイトと鉄を複合化した可視光で働く光触媒粒子などを水に加えた光触媒洗浄液を用いたPCBの分離回収方法が注目されている。
光触媒洗浄液は、光を照射させることで活性酸素を発生することから、光触媒洗浄液中に浸漬させた前記電気機器から、付着するPCBの結合を切断して剥離させることができ、PCB汚染油(もしくはPCB含有油)が光触媒洗浄液の液面に浮上することで、容易にPCBだけを分離し回収することができる。
Conventionally, various methods for removing PCB from PCB-contaminated waste electrical equipment such as transformers, capacitors, instrument transformers, reactors, discharge coils, and OF cables have been proposed.
In particular, in recent years, a method for separating and recovering PCBs using a photocatalyst cleaning solution in which photocatalyst particles working with visible light, which is a composite of titanium oxide, apatite, and iron are added to water has attracted attention.
Since the photocatalyst cleaning liquid generates active oxygen by irradiating light, it is possible to cut off the bond of the adhering PCB from the electric device immersed in the photocatalyst cleaning liquid and peel it off. PCB-containing oil) floats on the surface of the photocatalyst cleaning liquid, so that only PCB can be easily separated and recovered.

そして、この光触媒洗浄液を用いてPCBを除去する発明として、「廃電気機器からPCB油を抜く抜油工程と、抜油した廃電気機器を一次洗浄槽に収容し、光触媒洗浄液により洗浄する一次洗浄工程と、一次洗浄を終了した廃電気機器を解体する解体工程と、解体した廃電気機器を洗浄する二次洗浄工程と、二次洗浄工程を終えた前記解体廃電気機器を乾燥する乾燥工程とを組み合わせたことを特徴とするPCB汚染廃電気機器の処理システム」に係る発明が開示されている(特許文献1)。 And as invention which removes PCB using this photocatalyst washing | cleaning liquid, "the oil removal process which drains PCB oil from waste electrical equipment, the primary washing process which accommodates the drained waste electrical equipment in the primary washing tank, and wash | cleans with a photocatalyst washing liquid, A combination of a disassembly process for dismantling the waste electrical equipment that has finished the primary cleaning, a secondary cleaning process for cleaning the dismantled waste electrical equipment, and a drying process for drying the dismantled waste electrical equipment that has finished the secondary cleaning process An invention relating to a “processing system for PCB-contaminated waste electrical equipment characterized by the above” is disclosed (Patent Document 1).

当該発明によれば、前記のとおり、廃電気機器からPCBを抜く抜油工程だけで96%程度のPCB油を除去することができ(特許文献1の明細書段落番号「0005」)、さらに、抜油した廃電気機器を一次洗浄槽に収容し、光触媒洗浄液により洗浄(一次洗浄)を行うため、この時点でほとんどのPCB油を除去することができる。
また、当該発明は、一次洗浄した廃電気機器を解体し、解体した廃電気機器をさらに二次洗浄することで、「PCB油の残留がなくなり、洗浄したPCB汚染廃電気機器を通常の廃棄物と同様に取り扱うことができる効果がある(特許文献1の明細書段落番号「0006」)」。
According to the present invention, as described above, about 96% of PCB oil can be removed only by the oil removal step of removing PCB from waste electrical equipment (the paragraph number “0005” in the specification of Patent Document 1). Since the waste electrical equipment is housed in the primary cleaning tank and cleaned with the photocatalyst cleaning liquid (primary cleaning), most of the PCB oil can be removed at this point.
Further, the present invention dismantles the waste electrical equipment that has been primarily cleaned, and further performs secondary cleaning of the waste electrical equipment that has been disassembled, so that “residual PCB oil is eliminated and the washed PCB-contaminated waste electrical equipment is treated as normal waste. It can be handled in the same manner as the above (Patent Document 1 specification, paragraph number “0006”) ”.

しかし、前記発明は、廃電気機器からPCBを抜く抜油工程だけで、「PCB汚染廃電気機器の上蓋を取り外し、交換ノズル式抜油法により前記廃電気機器内へ水を送り込み、これを汲出する操作を繰り返して前記廃電気機器内の残留PCB油及び内壁等に付着しているPCB油を順次洗浄する(特許文献1の明細書段落番号「0009」)」工程を経る必要があり、手間がかかるだけでなく、多大な作業時間を要する。 However, the invention described above is an operation of removing the PCB from the waste electrical equipment and removing the upper cover of the PCB-contaminated waste electrical equipment, feeding water into the waste electrical equipment by the replacement nozzle type oil removal method, and pumping it out. It is necessary to go through the process of sequentially cleaning the residual PCB oil in the waste electrical equipment and the PCB oil adhering to the inner wall etc. (paragraph number “0009” in the specification of Patent Document 1). Not only that, it takes a lot of work time.

そして、「廃電気機器を一次洗浄槽内へそのまま投入し、光触媒洗浄液により、2時間ほど一次洗浄を行う」(特許文献1の明細書段落番号「0011」)が、一次洗浄の時点で、少なくとも2時間以上の作業時間を費しており、多数の廃電気機器を一度に洗浄する場合には、とても利用できるものではない。 And, “the waste electrical equipment is put into the primary cleaning tank as it is, and the primary cleaning is performed for about 2 hours with the photocatalyst cleaning liquid” (paragraph number “0011” in the specification of Patent Document 1) at least at the time of the primary cleaning. It takes more than 2 hours of work time and is not very useful when cleaning many waste electrical devices at once.

光触媒洗浄液を使ったPCBの除去方法は、PCB汚染廃電気機器を浸漬させた光触媒洗浄液に光を照射することで、PCB汚染廃電気機器に付着したPCBを当該機器から剥離させて、PCBだけを分離して回収するものであるから、PCB汚染廃電気機器に付着したPCBを、当該機器から如何に早く剥離させられるかが、作業時間を短縮するポイントになる。 The PCB removal method using the photocatalyst cleaning liquid is to irradiate the photocatalyst cleaning liquid in which the PCB-contaminated waste electrical equipment is immersed, so that the PCB attached to the PCB-contaminated waste electrical equipment is peeled off from the equipment, and only the PCB is removed. Since they are separated and collected, how quickly the PCB attached to the PCB-contaminated waste electrical equipment can be peeled off from the equipment is a point for shortening the working time.

しかしながら、洗浄対象物であるPCB汚染廃電気機器は、トランス、コンデンサ、計器用変成器、リアクトル、放電コイル、OFケーブルなど、様々な形状、構造、素材のものがあり、大きさも一様ではないため、作業効率の向上、作業時間の短縮のためには、機器に合わせた洗浄装置を使用することが、作業効率の向上と作業時間の短縮を図るうえで重要である。 However, PCB-contaminated waste electrical equipment that is the object to be cleaned has various shapes, structures, and materials such as transformers, capacitors, instrument transformers, reactors, discharge coils, and OF cables, and the sizes are not uniform. Therefore, in order to improve the work efficiency and shorten the work time, it is important to use a cleaning device suitable for the equipment in order to improve the work efficiency and shorten the work time.

そこで、本発明は、光触媒洗浄液を用い、PCB汚染廃電気機器の形状や種類に合わせて最適な洗浄を行うことができる噴射装置によって、極めて短時間に効率的にPCBを除去できる洗浄装置を提供することを課題とする。 Therefore, the present invention provides a cleaning device that can remove PCB efficiently in an extremely short time by using an injection device that can perform optimal cleaning according to the shape and type of PCB-contaminated waste electrical equipment using a photocatalyst cleaning liquid. The task is to do.

被洗浄物であるPCB汚染廃電気機器は、トランス、コンデンサ、計器用変成器、リアクトル、放電コイル、OFケーブルなどのPCBに汚染された廃電気機器であって、特に、表面を洗浄する必要がある、鉄心などのケーシングの中身を意味する。
本実施例の洗浄装置では、このPCB汚染廃電気機器を、洗浄槽2内の筒形噴射容器11に収容することで、PCB汚染廃電気機器の表面を洗浄する。
PCB-contaminated waste electrical equipment to be cleaned is waste electrical equipment contaminated with PCB, such as transformers, capacitors, instrument transformers, reactors, discharge coils, OF cables, etc. It means the contents of a casing such as an iron core.
In the cleaning apparatus of the present embodiment, this PCB-contaminated waste electrical device is accommodated in the cylindrical injection container 11 in the cleaning tank 2 to clean the surface of the PCB-contaminated waste electrical device.

光触媒洗浄液4は、酸化チタンとアパタイトと鉄を複合化した可視光で働く光触媒粒子などを加えたもので、光の照射により油などの有機物を水や二酸化炭素に分解することができるものである。 The photocatalyst cleaning liquid 4 is a liquid to which titanium oxide, apatite, and iron are combined and photocatalyst particles that work with visible light are added. The photocatalyst cleaning liquid 4 can decompose organic substances such as oil into water and carbon dioxide by light irradiation. .

PCB汚染廃電気機器を筒形噴射容器11に収容するには、筒形噴射容器11内に投入するだけで良い。
筒形噴射容器11は、箱型(四角形、多角形)や筒型(丸形)などの筒形に形成されており、その容積内であれば、どのようなPCB汚染廃電気機器でも投入して洗浄できる。
In order to accommodate the PCB-contaminated waste electrical device in the cylindrical injection container 11, it is only necessary to put it into the cylindrical injection container 11.
The cylindrical injection container 11 is formed in a cylindrical shape such as a box shape (square, polygonal shape) or a cylindrical shape (round shape). Can be washed.

筒形噴射容器11には、アーム10が連結されており、このアーム10を通じて、筒形噴射容器11内に光触媒洗浄液4が供給(送水)される。
筒形噴射容器11は、アーム10との連結部分において、取り付け、取り外しが可能になっており、例えば、被洗浄物であるPCB汚染廃電気機器の大きさに合わせ、異なるサイズのものに替えることができる。
An arm 10 is connected to the cylindrical injection container 11, and the photocatalyst cleaning liquid 4 is supplied (water supplied) into the cylindrical injection container 11 through the arm 10.
The cylindrical injection container 11 can be attached and detached at the connecting portion with the arm 10. For example, the cylindrical injection container 11 should be replaced with a different size according to the size of the PCB-contaminated waste electrical equipment that is the object to be cleaned. Can do.

筒形噴射容器11は、PCB汚染廃電気機器を載置する載置板1が取り付けられている。
載置板1は、筒形噴射容器11内に収容するPCB汚染廃電気機器を直接載置するための板状の部材である。
1つの筒形噴射容器11内に、複数のPCB汚染廃電気機器を合計数百kg分収容するため、PCB汚染廃電気機器を直接筒形噴射容器11の底面に載置するのではなく、載置板1に載置するようにしたものである。
The cylindrical injection container 11 is provided with a mounting plate 1 on which PCB-contaminated waste electrical equipment is mounted.
The mounting plate 1 is a plate-like member for directly mounting the PCB-contaminated waste electrical device accommodated in the cylindrical injection container 11.
Since a plurality of PCB-contaminated waste electrical devices are accommodated in a single cylindrical injection container 11 for a total of several hundred kg, the PCB-contamination waste electrical equipment is not placed directly on the bottom surface of the cylindrical injection container 11 but mounted. This is placed on the mounting plate 1.

載置板1には、光触媒洗浄液4を噴射させる複数の噴射孔1aが形成されている。
噴射孔1aは、載置板1を貫通する孔であり、この孔を通じて、アーム10から供給された光触媒洗浄液4が筒形噴射容器11の上方に噴射される。
噴射孔1aは、水流を変化させるために、孔の大きさ(径)を変えたり、孔自体の形状を変化させることもできる。
A plurality of injection holes 1 a for injecting the photocatalyst cleaning liquid 4 are formed in the mounting plate 1.
The injection hole 1 a is a hole that penetrates the mounting plate 1, and the photocatalyst cleaning liquid 4 supplied from the arm 10 is injected above the cylindrical injection container 11 through this hole.
The injection hole 1a can change the size (diameter) of the hole or change the shape of the hole itself in order to change the water flow.

載置板1には、光触媒洗浄液4を斜め上方に噴射させる噴射ノズル1bが形成されている。
噴射ノズル1bは、載置板1から斜め上方に向かって突出した形状をなしており、載置板1から噴射ノズル1bの噴射口まで貫通する孔が形成されており、この孔を通じて、光触媒洗浄液4が噴射される。
噴射ノズル1bは、筒形噴射容器11内に上昇旋回する水流を発生させることができれば、斜め上方以外にも、噴射方向を変えることができる。
The mounting plate 1 is formed with an injection nozzle 1b for injecting the photocatalyst cleaning liquid 4 obliquely upward.
The injection nozzle 1b has a shape projecting obliquely upward from the mounting plate 1, and a hole penetrating from the mounting plate 1 to the injection port of the injection nozzle 1b is formed, through which the photocatalytic cleaning liquid is formed. 4 is injected.
The injection nozzle 1b can change the injection direction in addition to the diagonally upward direction as long as it can generate a water flow that rises and turns in the cylindrical injection container 11.

筒形噴射容器11には、図2、4のとおり、アーム10から分岐する噴射パイプ3が取り付けられている。
図1の筒形噴射容器11は、この噴射パイプ3を備えていないが、載置板1部分の構成は、図2の載置板1と同様である(図3は、図1と2に共通の構成である)。
噴射パイプ3は、アーム10から分岐して筒形噴射容器11の周囲に配され、筒形噴射容器11の壁面に接続されており、接続された噴射口から筒形噴射容器11内に光触媒洗浄液4を噴射するように形成されている。
噴射パイプ3から筒形噴射容器11に接続する噴射口の数は、増減させることができる。
複数の噴射口を形成するようにすれば、筒形噴射容器11の壁面から噴射される光触媒洗浄液4の勢いが強くなり、より大きな水流を発生させることができる。
また、噴射口付近の噴射パイプ3の接続角度(向き)を変えて、光触媒洗浄液4が筒形噴射容器11内に噴射される方向を変えることもできる。
このような噴射パイプ3を備えることで、噴射パイプ3から噴射された光触媒洗浄液4によって、筒形噴射容器11内を上昇旋回するように水流が発生し、光触媒洗浄液4が全体的に洗浄槽2内を流動する結果、PCB汚染廃電気機器表面に光が照射されて起こる光触媒の反応効率を高めてくれる。
これにより、洗浄力も高まり、洗浄時間をさらに短縮できる。
As shown in FIGS. 2 and 4, the injection pipe 3 branched from the arm 10 is attached to the cylindrical injection container 11.
Although the cylindrical injection container 11 of FIG. 1 does not include this injection pipe 3, the configuration of the mounting plate 1 is the same as that of the mounting plate 1 of FIG. 2 (FIG. 3 is similar to FIGS. 1 and 2). It is a common configuration).
The injection pipe 3 branches from the arm 10 and is arranged around the cylindrical injection container 11 and is connected to the wall surface of the cylindrical injection container 11, and the photocatalyst cleaning liquid enters the cylindrical injection container 11 from the connected injection port. 4 is injected.
The number of injection ports connected to the cylindrical injection container 11 from the injection pipe 3 can be increased or decreased.
If a plurality of injection ports are formed, the momentum of the photocatalyst cleaning liquid 4 injected from the wall surface of the cylindrical injection container 11 becomes strong, and a larger water flow can be generated.
Further, the direction in which the photocatalyst cleaning liquid 4 is injected into the cylindrical injection container 11 can be changed by changing the connection angle (direction) of the injection pipe 3 near the injection port.
By providing such an injection pipe 3, a water flow is generated by the photocatalyst cleaning liquid 4 injected from the injection pipe 3 so as to ascend and swirl inside the cylindrical injection container 11, so that the photocatalytic cleaning liquid 4 is entirely contained in the cleaning tank 2. As a result of flowing inside, the efficiency of the photocatalyst that occurs when the surface of PCB-contaminated waste electrical equipment is irradiated with light is increased.
Thereby, the cleaning power is also increased, and the cleaning time can be further shortened.

アーム10を通じて供給され、筒形噴射容器11の噴射孔1a、噴射ノズル1b、噴射パイプ3から噴射される光触媒洗浄液4は、圧縮空気を混入させることができる。
圧縮空気を混入させた光触媒洗浄液を、筒形噴射容器11に収容されているPCB汚染廃電気機器の表面に噴射することで、気泡の浮力によってPCBや埃、塵を液面に素早く浮かせることができる。
このような気液混合の光触媒洗浄液4を噴射することで(バブリング洗浄)、単に光触媒洗浄液4を貯留した洗浄槽2内にPCB汚染廃電気機器を浸漬させるだけの洗浄方法に比べて、極めて高い洗浄効果を得られる。
The photocatalyst cleaning liquid 4 supplied through the arm 10 and injected from the injection hole 1a, the injection nozzle 1b, and the injection pipe 3 of the cylindrical injection container 11 can be mixed with compressed air.
By injecting the photocatalyst cleaning liquid mixed with compressed air onto the surface of the PCB-contaminated waste electrical equipment housed in the cylindrical injection container 11, the buoyancy of the bubbles can quickly float PCB, dust, and dust on the liquid surface. it can.
By jetting the photocatalyst cleaning liquid 4 in such a gas-liquid mixture (bubbling cleaning), it is extremely higher than a cleaning method in which the PCB-contaminated waste electrical device is simply immersed in the cleaning tank 2 in which the photocatalytic cleaning liquid 4 is stored. A cleaning effect can be obtained.

筒形噴射容器11の内壁には、光源9が設けられている。
光源9は、紫外線などの光触媒洗浄液4中の光触媒粒子を反応させることができるものであれば、どのような光源9でも利用できる。
光源9が筒形噴射容器11の内壁に設けられていることで、筒形噴射容器11の側面からPCB汚染廃電気機器の表面に光が照射され、効率良く、且つ、短時間で、PCB汚染廃電気機器の表面のPCBを剥離させることができる。
特に、PCB汚染廃電気機器の表面は、光触媒洗浄液4が勢い良く噴射され、筒形噴射容器11とPCB汚染廃電気機器の隙間を光触媒洗浄液4が流動するため、光触媒の反応が促進され、PCB汚染廃電気機器の表面のPCBを効果的に、且つ、短時間で剥離することができる。
A light source 9 is provided on the inner wall of the cylindrical injection container 11.
As the light source 9, any light source 9 can be used as long as it can react the photocatalyst particles in the photocatalyst cleaning liquid 4 such as ultraviolet rays.
Since the light source 9 is provided on the inner wall of the cylindrical injection container 11, light is irradiated from the side surface of the cylindrical injection container 11 to the surface of the PCB-contaminated waste electrical device, and the PCB contamination is efficiently performed in a short time. PCB on the surface of waste electrical equipment can be peeled off.
In particular, the photocatalyst cleaning liquid 4 is jetted vigorously on the surface of the PCB-contaminated waste electrical equipment, and the photocatalytic cleaning liquid 4 flows through the gap between the cylindrical injection container 11 and the PCB-contaminated waste electrical equipment. The PCB on the surface of the contaminated waste electrical device can be peeled off effectively and in a short time.

PCB汚染油(もしくはPCB含有油)は、PCB汚染廃電気機器から剥離すると液面に浮上することから、洗浄槽2内の光触媒洗浄液4をオーバーフローさせて、洗浄槽2外に光触媒洗浄液4が溢れ出るようにすることで、容易にPCBだけを分離し回収することができる。
PCBの回収には、洗浄槽2に隣接するように別の槽を設けて、洗浄槽2からオーバーフローした光触媒洗浄液4だけが洗浄槽2に送水されるようにして、最終的にPCBを分離槽で分離して回収することもできる。
また、上記した別の槽は、さらに複数の槽に仕切ることで分離精度を上げることができ、最終的には、PCBは遠心分離機などで分離して回収することができる。
The PCB contaminated oil (or PCB-containing oil) floats on the liquid surface when it is separated from the PCB contaminated waste electrical equipment, so that the photocatalyst cleaning liquid 4 in the cleaning tank 2 overflows and the photocatalytic cleaning liquid 4 overflows outside the cleaning tank 2. By making it come out, only the PCB can be easily separated and recovered.
For the PCB recovery, another tank is provided adjacent to the cleaning tank 2 so that only the photocatalyst cleaning liquid 4 overflowed from the cleaning tank 2 is sent to the cleaning tank 2, and finally the PCB is separated. It can also be separated and recovered with
Moreover, the above-mentioned another tank can be further divided into a plurality of tanks to increase the separation accuracy, and finally, the PCB can be separated and collected by a centrifuge or the like.

洗浄槽2から別の槽にPCBがオーバーフローする際、勢い良くオーバーフローしてしまうと、せっかく別の槽の液面で浮遊しているPCBが撹拌されてしまい、光触媒洗浄液4とPCBの分離がなされなくなってしまう。
そこで、洗浄槽2と別の槽の間に貫通孔を設け、この貫通孔を仕切り(オーバーフロー調整ゲート)によって塞いだり、開いたりすることで、洗浄槽2と別の槽に貯留する光触媒洗浄液4の量を調整し、洗浄槽2から勢い良くオーバーフローしないように、オーバーフローの流量を調整できるようにすることもできる。
When the PCB overflows from the cleaning tank 2 to another tank, if it overflows vigorously, the PCB floating on the liquid surface of the other tank will be stirred, and the photocatalyst cleaning liquid 4 and the PCB are separated. It will disappear.
Therefore, a photocatalyst cleaning liquid 4 stored in a tank separate from the cleaning tank 2 is provided by providing a through hole between the cleaning tank 2 and another tank, and closing or opening the through hole with a partition (overflow adjusting gate). It is also possible to adjust the flow rate of the overflow so that the overflow does not overflow from the cleaning tank 2 vigorously.

洗浄槽2の液面にはPCBが浮遊するが、このPCBを早く洗浄槽2から隣の槽にオーバーフローさせることで、早く確実にPCBを分離回収し、作業時間を短縮できる。
そこで、洗浄槽2の壁側の液面付近に、光触媒洗浄液4を噴射する噴射口(PCB追い出しシャワー)を設け、PCBを洗浄槽2から隣の槽に早くオーバーフローさせるようにすることもできる。
洗浄槽2の底面には、洗浄によって溜まった沈殿物を排出するための管を設けることもできる。
PCBを分離して回収した光触媒洗浄液4は、ポンプで洗浄槽2へと送水することで、再度洗浄に使用できる。
PCB floats on the liquid surface of the cleaning tank 2. By quickly overflowing this PCB from the cleaning tank 2 to the adjacent tank, the PCB can be separated and recovered quickly and the working time can be shortened.
Therefore, an injection port (PCB discharge shower) for injecting the photocatalyst cleaning liquid 4 can be provided near the liquid surface on the wall side of the cleaning tank 2 so that the PCB can quickly overflow from the cleaning tank 2 to the adjacent tank.
On the bottom surface of the cleaning tank 2, a pipe for discharging the sediment accumulated by the cleaning can be provided.
The photocatalyst cleaning liquid 4 separated and recovered from the PCB can be used for cleaning again by supplying water to the cleaning tank 2 with a pump.

光触媒洗浄液4を供給(送水)する際、コンプレッサーで圧縮空気をアーム10内に注入し、気液混合の光触媒洗浄液4を噴射するようにすることもできる。
これにより、PCB汚染廃電気機器をバブリング洗浄することができ、気泡の浮力によってPCBや埃、塵を液面に素早く浮かせ、より早くPCBを分離回収できる。
When supplying (water feeding) the photocatalyst cleaning liquid 4, it is also possible to inject compressed air into the arm 10 with a compressor and to inject the photocatalyst cleaning liquid 4 mixed with gas and liquid.
Accordingly, the PCB-contaminated waste electrical device can be bubble-washed, and the PCB, dust, and dust can be quickly floated on the liquid surface by the buoyancy of the bubbles, and the PCB can be separated and recovered more quickly.

筒形噴射容器11内の載置板1に形成されている噴射ノズル1bは、先端の噴射口を、幅狭に形成することもできる。
これにより、噴射ノズル1bから噴射される光触媒洗浄液4の勢いを増加させることができ、洗浄力を高め、洗浄時間をより短縮できる。
The injection nozzle 1b formed on the mounting plate 1 in the cylindrical injection container 11 can also have a narrow injection port at the tip.
Thereby, the momentum of the photocatalyst cleaning liquid 4 sprayed from the spray nozzle 1b can be increased, the cleaning power can be increased, and the cleaning time can be further shortened.

Any configuration without the injection pipe 3 can be selected.

分離槽13には、貯留する光触媒洗浄液4を回収する循環パイプ18が配管されている。
分離槽13から回収した光触媒洗浄液4は、ポンプによって、循環パイプ18から回転基体12に送水され、回転基体12から延びるアーム10を通じて筒形噴射容器11内に噴射され、洗浄槽2での洗浄に再利用される。
このようにして、光触媒洗浄液4を循環させる。
The separation tank 13 is provided with a circulation pipe 18 for collecting the stored photocatalyst cleaning liquid 4.
The photocatalyst cleaning liquid 4 recovered from the separation tank 13 is pumped by a pump from the circulation pipe 18 to the rotary base 12 and sprayed into the cylindrical injection container 11 through the arm 10 extending from the rotary base 12 for cleaning in the cleaning tank 2. Reused.
In this way, the photocatalyst cleaning liquid 4 is circulated.

循環パイプ18は、回転継手19によって、回転基体12と連結されている。
回転基体12は、回転基体12から延びるアーム10の先端で筒形噴射容器11と連結しており、その状態で周方向に回転する。
筒形噴射容器11は、回転基体12が周方向に回転することで、洗浄槽2内を周回しながらPCB汚染廃電気機器を洗浄することができる。
この回転によって、PCB汚染廃電気機器を洗浄している間は、PCB汚染廃電気機器を洗浄槽2内に浸漬させておき、筒形噴射容器11内に収容したり、PCB汚染廃電気機器を筒形噴射容器11から取り出したりする作業を、任意の位置で全て行うことができるため、作業者を複数配置させたり、作業者が装置の周りを移動することがなくなり、作業効率が向上する。
The circulation pipe 18 is connected to the rotary base 12 by a rotary joint 19.
The rotating base 12 is connected to the cylindrical injection container 11 at the tip of the arm 10 extending from the rotating base 12, and rotates in the circumferential direction in this state.
The cylindrical injection container 11 can clean the PCB-contaminated waste electrical equipment while rotating around the cleaning tank 2 by rotating the rotating base 12 in the circumferential direction.
While the PCB-contaminated waste electrical device is being cleaned by this rotation, the PCB-contaminated waste electrical device is immersed in the cleaning tank 2 and accommodated in the cylindrical injection container 11 or the PCB-contaminated waste electrical device is Since all the operations of taking out from the cylindrical injection container 11 can be performed at an arbitrary position, a plurality of workers are not arranged or the workers do not move around the apparatus, and the work efficiency is improved.

回転基体12は、電気の配線と光触媒洗浄液4とが接触しないように、仕切り用のフランジ20が取り付けられている。
また、回転基体12の軸上には、空気の吹出孔を備えたエアー吹出装置21が設けられており、2本の循環パイプ18から回転基体12内に光触媒洗浄液4が流れ込んで合流するところに、エアー吹出装置21から圧縮空気が吹き出されるようになっている。
このエアー吹出装置21から圧縮空気を注入することによって、光触媒洗浄液4に微細な気泡が発生し、筒形噴射容器11内に噴射される光触媒洗浄液4をバブル化できる。
この微細気泡を含んだ光触媒洗浄液4によって、PCB汚染廃電気機器をバブリング洗浄することで、気泡の浮力によってPCBや埃、塵を液面に素早く浮かせ、より早くPCB汚染廃電気機器を洗浄でき、単に光触媒洗浄液4を貯留した洗浄槽2内にPCB汚染廃電気機器を浸漬させるだけの洗浄方法に比べて、極めて高い洗浄効果を得られる。

Compared with a cleaning method in which the PCB-contaminated waste electrical device is simply immersed in the cleaning tank 2 in which the photocatalyst cleaning liquid 4 is stored, an extremely high cleaning effect can be obtained.

洗浄槽2の液面に浮遊するPCBは、オーバーフローして分離槽13に流れ込む。
分離槽13の液面に浮遊するPCBは、オーバーフローして回収槽14に流れ込む。
回収槽14に流れ込んだPCBは、分離タンク22に流れ込み、さらに分離タンク22内の複数に分かれた槽でPCBを分離し、最終的には遠心分離機によってPCBを回収する。

The PCB that has flowed into the collection tank 14 flows into the separation tank 22, further separates the PCB in a plurality of tanks within the separation tank 22, and finally collects the PCB by a centrifuge.

洗浄槽2から分離槽13にPCBがオーバーフローする際、勢い良くオーバーフローしてしまうと、せっかく分離槽13の液面で浮遊しているPCBが撹拌されてしまい、いつまで経っても、光触媒洗浄液4とPCBとを分離できなくなってしまう。
そこで、洗浄槽2と分離槽13の間に貫通孔を設け、この貫通孔を仕切り(オーバーフロー調整ゲート23)によって塞いだり、開いたりすることで、洗浄槽2から勢い良くオーバーフローしないように洗浄槽2と分離槽13に貯留する光触媒洗浄液4の量を調整し、オーバーフローの流量を調整できるようにしている。

On the bottom surface of the cleaning tank 2, a discharge pipe 25 is provided for discharging the sediment accumulated by the cleaning.

筒形噴射容器11内の載置板1に形成されている噴射ノズル1bは、先端の噴射口を、幅狭に形成することもできる。
これにより、噴射ノズル1bから噴射される光触媒洗浄液4の勢いを増加させることができ、洗浄力を高め、洗浄時間をより短縮できる。

このような構成の洗浄装置によって、PCB汚染廃電気機器の表面を洗浄しながら、筒形噴射容器11内を上昇旋回するように水流が発生し、光触媒洗浄液4が全体的に洗浄槽2内を流動する結果、PCB汚染廃電気機器表面に光が照射されて起こる光触媒の反応効率を高めてくれる。
これにより、洗浄力も高まり、洗浄時間をさらに短縮できる。
While the surface of the PCB-contaminated waste electrical device is cleaned by the cleaning device having such a configuration, a water flow is generated so as to move up and swivel in the cylindrical injection container 11, and the photocatalyst cleaning liquid 4 is entirely contained in the cleaning tank 2. As a result of the flow, the reaction efficiency of the photocatalyst caused by irradiating the surface of the PCB-contaminated waste electrical device with light is increased.
