Description

本発明は河川、貯水池、ダム、海などに流れ出た油を回収するための吸着シート及び吸着装置に関するものである。   The present invention relates to an adsorption sheet and an adsorption device for recovering oil that has flowed into a river, a reservoir, a dam, the sea, or the like.

タンカーなどの海難事故によって大量の油が流出した場合、この油は回収しなくてはならい。最も一般的な方法としては、オイルフェンスを張り巡らせて油の拡散を防止し、油の海岸漂着を回避することが最も重要とされている。
すなわち、浮遊原油の周囲にオイルフェンスを張り、このオイルフェンス内の浮遊原油を回収船上の作業者が長い柄付ひしゃくで汲み上げたり、又はオイルフェンスの中に親油性素材よりなるシート状の油吸着材を投入し、該油吸着材に油を吸着することにより流出油を回収することが出来る。さらに、油処理剤を散布することで化学的に処理する場合もある。 If a large amount of oil is spilled due to a marine accident such as a tanker, this oil must be recovered. As the most general method, it is most important to stretch the oil fence to prevent the oil from spreading and to avoid the oil shore drift.
In other words, an oil fence is installed around floating crude oil, and the worker on the recovery ship pumps up the floating crude oil in the oil fence with a long ladle or adsorbs a sheet of oil made of a lipophilic material in the oil fence. The spilled oil can be recovered by charging the oil and adsorbing the oil to the oil adsorbent. Furthermore, chemical treatment may be performed by spraying an oil treatment agent.

しかし、浮遊原油を作業者が長い柄付ひしゃくで汲み上げる方法では、汲み上げたものが油だけでなくほとんど水であるため作業効率は非常に悪い。また、大量の原油の流出事故に対して迅速に対応できず、流出した浮遊原油が次第に広範囲に拡散して海岸の近くの漁場や海苔、貝類の養殖場へ大量の原油が押し寄せ、水産資源を全滅し兼ねないという問題がある。   However, in the method where an operator pumps floating crude oil with a long ladle, work efficiency is very poor because what is pumped is almost water as well as oil. In addition, a large amount of crude oil spills cannot be responded to promptly, and the spilled floating crude oil gradually spreads over a wide area. There is a problem that it can be annihilated.

また、シート状の油吸着材を投入して油の吸着を行う方法では、投下したシートが風の影響を受けやすいため、互いに重なったり、各シート間に隙間ができたりして流出油を完全に回収することが出来ない。一方、油を吸着したシートを引き上げて回収するのにも１枚１枚回収するため、多大な労力および時間を要する。
海上に流出した油の場合には、多少の波はあっても大きな流れはないために、シート状の油吸着材を投入して吸着することは出来るが、流れのある河川に流出した油を回収することは不可能である。 In addition, in the method where oil is adsorbed by using a sheet-like oil adsorbent, the dropped sheets are easily affected by the wind, so they overlap each other and a gap is formed between the sheets, so that the spilled oil is completely removed. Cannot be recovered. On the other hand, it takes a lot of labor and time to collect one sheet of paper even when the oil-adsorbed sheet is pulled up and collected.
In the case of oil spilled on the sea, there is no big flow even if there are some waves, so it is possible to absorb it by inserting a sheet-like oil adsorbent, but the oil spilled into the flowing river It is impossible to recover.

さらに、油処理剤を使用する方法は、油を分散して自然浄化の促進を図るもので、初期・少量の流出油のみ効果が期待できるに止まり、処理剤が残留して生態系（海産物など）に影響する虞も高い。
河川の油流出事故における流出油による汚染は、河川の流れで広範囲の下流水域に広がり、飲料水を犯す危険もあり、川底の石や砂利に付着した油を完全に取り除くことは極めて困難である。 Furthermore, the method of using an oil treatment agent disperses the oil and promotes natural purification. Only the initial and small amount of spilled oil can be expected to be effective, and the treatment agent remains and the ecosystem (such as marine products). ) Is also likely to be affected.
Contamination due to oil spills in a river oil spill accident spreads to a wide range of downstream waters in the river flow, and there is a risk of committing drinking water, and it is extremely difficult to completely remove oil adhering to riverbed stones and gravel .

Polypropylene is used as a raw material, and a long nonwoven fabric made of long fibers obtained by a spunbond method is folded in a zigzag and stored in a storage box. At the time of oil recovery, it is dropped on the sea surface or water surface in a zigzag folded state, and the ropes connected to both sides of the oil adsorption sheet are stretched by pulling from both sides with a small ship, surrounding the spilled oil and recovered To do.

このように流出した油を回収する方法は色々知られているが、課題も残されている。本発明が解決しようとする課題は、流れがある河川、海、又はダムであっても、流出した油を効率よく回収をすることが出来る油の吸着シート及び吸着装置を提供する。   Various methods for recovering the oil thus spilled are known, but problems remain. The problem to be solved by the present invention is to provide an oil adsorbing sheet and an adsorbing device capable of efficiently collecting the oil that has flowed out even in a river, sea, or dam with a flow.

本発明に係る油吸着シートは四角形を成し、その材質は油の吸着性に優れたものが用いられ、具体的な材質に関しては限定しないが、主として植物系天然繊維（例えば、カポック）を主体とした布（不織布を含む）である。そして、この四角形の吸着シートのコーナーには穴を貫通してリング状の補強具を嵌めた形態としている。
実際の油吸着作業に当たっては、複数枚の吸着シートを繋いで両側にはロープを延ばして構成した吸着装置が用いられ、その形態は万国旗状としている。 The oil adsorbing sheet according to the present invention has a quadrangular shape, and its material is excellent in oil adsorbing properties. Although the specific material is not limited, it is mainly composed of plant-based natural fibers (for example, Kapok). Cloth (including non-woven fabric). And it is set as the form which penetrated the hole and fitted the ring-shaped reinforcement tool in the corner of this square adsorption sheet.
In actual oil adsorbing work, an adsorbing device constructed by connecting a plurality of adsorbing sheets and extending ropes on both sides is used, and its form is a national flag.

複数枚の吸着シートはその上縁が繋がっているが、下縁側コーナーに穴を設けることで、この穴を利用して連結具にて隣り合う吸着シートの下縁側を繋ぐことが出来る。また、コーナーに設けている穴に連結具を係止して２枚の吸着シートを重ねた状態で使うことも出来る。
そこで、両側へ延びたロープを用いて小型船舶で両側より引張って延張し、流出油を取り囲んで回収することが出来、また河川に流れる油を回収する場合には、両側のロープは流れを跨いで両岸に固定される。 The upper edges of the plurality of suction sheets are connected to each other, but by providing a hole in the lower edge side corner, the lower edge side of the adjacent suction sheets can be connected by a connector using this hole. Moreover, it can also be used in a state where two adsorbing sheets are overlapped by locking a connecting tool in a hole provided in a corner.
Therefore, it is possible to pull and extend from both sides with a small ship using ropes extending to both sides, and surround and collect the spilled oil, and when collecting the oil flowing into the river, the ropes on both sides flow. It is fixed on both banks.

本発明の吸着シートの具体的な材質は限定しないが、例えば天然繊維であるカポックを使用したものであれば優れた吸着力を有し、吸着シートの重量に対してその３０倍以上の油を吸着することが出来る。そして、１枚当たりの吸着性が高いために使用する吸着シートの枚数は少なくて済み、結果的には経済性に優れている。
また、カポックは繊維の約８０％が中空で撥水性があり、その為に水を寄せ付けず、油を吸着した後であっても水面に浮くことが出来、使用後の回収が便利である。 Although the specific material of the adsorption sheet of the present invention is not limited, for example, if it uses a natural fiber kapok, it has an excellent adsorption force, and oil more than 30 times the weight of the adsorption sheet. Can be adsorbed. And since the adsorptivity per sheet is high, the number of adsorbing sheets to be used is small, and as a result, the economy is excellent.
Moreover, about 80% of the fibers of the Kapok are hollow and water-repellent. Therefore, Kapok does not attract water and can float on the water surface even after the oil is adsorbed.

そして、天然繊維カポックを主体とした吸着シートは環境に優しく、繊維が中空になっている為に吸着した油がした垂れ落ちることも殆どない。
一方、コーナーには穴を貫通しているために、該穴に連結具を係止して下縁側に別の吸着シートを繋ぐことが出来、また、流出した油の量が多い場合には、２枚乃至３枚重ねで使うことも可能となる。 The adsorbing sheet mainly composed of natural fiber kapok is environmentally friendly, and since the fibers are hollow, the adsorbed oil hardly drips.
On the other hand, because the corner penetrates the hole, it is possible to lock the connector in the hole and connect another suction sheet to the lower edge side, and when the amount of oil spilled is large, It is also possible to use two or three sheets.

図１は本発明に係る油の吸着シート１を示している実施例である。該吸着シート１は天然繊維カポックを主体とした不織布であり、該カポックはその繊維が中空状態で撥水性があり、約８０％が中空と成っている。その為に、該吸着シートは非常に軽くて水に浮くことが出来、しかも自重に対して約３０倍以上の油を吸着することが可能である。すなわち、１枚当たりの油吸着量が大きく、しかも油を吸着した状態であっても水に浮くことが出来る。その為に、油を吸着した吸着シートの回収は非常に楽である。   FIG. 1 shows an embodiment showing an oil adsorption sheet 1 according to the present invention. The adsorbing sheet 1 is a non-woven fabric mainly composed of natural fiber kapok, and the kapok is water-repellent when its fibers are hollow, and about 80% is hollow. Therefore, the adsorbing sheet is very light and can float on water, and can adsorb about 30 times more oil than its own weight. That is, the amount of oil adsorbed per sheet is large, and even when oil is adsorbed, it can float on water. Therefore, it is very easy to collect the adsorption sheet that has adsorbed oil.

図１に示す吸着シート１は四角形を成して、その各コーナーには穴２，２・・・が貫通し、穴２，２・・・の内周りには補強用のリング３，３・・・が嵌っている。この油吸着シート１は１枚で使用されることは殆どなく、一般的には複数枚の吸着シート１，１・・・が左右方向に繋がれて万国旗状を成した吸着装置を構成し、これにて海や湖に流れた油を取り囲んで回収することが出来ようにしている。   The suction sheet 1 shown in FIG. 1 has a rectangular shape, and holes 2, 2,... Penetrate through each corner, and reinforcing rings 3, 3,.・ ・ Is fitted. The oil adsorbing sheet 1 is rarely used as a single sheet. Generally, a plurality of adsorbing sheets 1, 1... This makes it possible to surround and recover the oil that has flowed into the sea or lake.

図２は複数枚の吸着シート１，１・・・を左右方向に繋いだ油吸着装置４を示している実施例である。油吸着装置４は同図に示すように上縁５，５・・・は折り返されてロープ６を抱き込み、各吸着シート１，１・・・の両側縁が互いに重なり合うように上縁５，５・・・にて繋がっている。そして、上記ロープ６は両側の吸着シート１，１から外方向へ大きく延びている。   FIG. 2 is an embodiment showing an oil adsorbing device 4 in which a plurality of adsorbing sheets 1, 1... Are connected in the left-right direction. In the oil adsorbing device 4, as shown in the figure, the upper edges 5, 5... Are folded back to embed the rope 6, and the upper edges 5, 5. It is connected at 5 ... The rope 6 extends greatly outward from the suction sheets 1 and 1 on both sides.

このように構成した油吸着装置４を使って流れ出た油を回収する具体的な方法に関しては特に限定しないが、両側へ延びるロープ６，６を船に繋ぎ、船を走らせることで流出した油の周囲を取り囲むように包囲することが出来る。
取り囲んだ領域を次第に縮小するならば、個々の吸着シート１，１・・・が海面に浮いている油に接することで該油は吸着される。 The specific method of collecting the oil flowing out using the oil adsorbing device 4 configured as described above is not particularly limited, but the oil that has flowed out by connecting the ropes 6 and 6 extending to both sides to the ship and running the ship. It can be surrounded so as to surround it.
If the surrounding area is gradually reduced, the oil is adsorbed by the individual adsorbing sheets 1, 1... Coming into contact with the oil floating on the sea surface.

ところで、本発明の吸着シート１は図１に示すように各コーナーにはリング３，３・・・が嵌って、補強した穴２，２・・・を形成している。そこで、この穴２，２・・・を利用することで連結具を介して他の吸着シート１を繋ぐことが出来る。
図３は図２に示した油吸着装置４の吸着シート１の下縁側に設けている穴２，２・・・を連結具７，７・・・にて繋いだ場合を示している。 By the way, as shown in FIG. 1, the adsorbing sheet 1 of the present invention has rings 3, 3,... Fitted into each corner to form reinforced holes 2, 2,. Therefore, by using these holes 2, 2..., Other suction sheets 1 can be connected via a connector.
3 shows a case where the holes 2, 2... Provided on the lower edge side of the suction sheet 1 of the oil adsorption device 4 shown in FIG.

図２に示す油吸着装置４を河川の両岸の間に掛け渡して配置する場合、川の流れによって上縁５に縫付けているロール６は滑らかな凹状に湾曲し、その為に各吸着シート１，１・・・の下縁側は広がって、側縁８，８の間には空間９が形成される。
そこで、上記空間９が大きくならないように吸着シート１，１・・・の下縁側に設けている穴２，２に係止する連結具７によって連結することが出来る。 When the oil adsorbing device 4 shown in FIG. 2 is arranged across both banks of the river, the roll 6 sewn on the upper edge 5 by the flow of the river is curved into a smooth concave shape. The lower edge side of the sheets 1, 1... Expands, and a space 9 is formed between the side edges 8, 8.
Therefore, the space 9 can be connected by a connecting tool 7 that is engaged with holes 2 and 2 provided on the lower edge side of the suction sheets 1, 1.

このように、下縁側の穴２，２・・・を連結具７，７・・・によって連結することで、空間９の拡大を防止することが出来ると共に、流れによって油吸着装置全体が大きく湾曲することを抑制出来る。ここで、穴に係止する連結具の具体的な構造は特に限定しないことにする。
図４はこの連結具の１具体例を示した場合であり、（ａ）は正面図、（ｂ）は側面図をそれぞれ表していて、同図の１０は係止部、１１は繋ぎ部を示し、両係止部１０，１０が繋ぎ部１１によって繋がれている。 In this way, by connecting the holes 2, 2... On the lower edge side with the connectors 7, 7..., The space 9 can be prevented from expanding, and the entire oil adsorbing device is greatly curved by the flow. Can be suppressed. Here, the specific structure of the connector locked in the hole is not particularly limited.
FIG. 4 shows a specific example of this connector, wherein (a) is a front view, (b) is a side view, 10 is a locking portion, and 11 is a connecting portion. As shown, both locking portions 10 and 10 are connected by a connecting portion 11.

上記繋ぎ部１１は湾曲自在な材質から成り、係止部１０はスリット溝１２，１２・・・が形成されて複数の係止片１３，１３・・・を有している。この係止部１０は先端外径ｄを基部外径Ｄより小さくした円錐台形としていて、この先端を穴２に嵌めて押圧するならば、各スリット溝１２，１２・・・は縮小して係止部１０の外径は縮まり、基部が穴２を貫通したところで各係止片１３，１３・・・は外方向へ拡張して係止部１０が穴２から外れることはなくなる。すなわち、係止部１０は穴２に係止する。
したがって、この係止部１０はワンタッチで穴２に嵌って係止することが出来、両側の吸着シート１，１を簡単に繋ぐことが可能である。 The connecting portion 11 is made of a bendable material, and the locking portion 10 is formed with slit grooves 12, 12... And has a plurality of locking pieces 13, 13. The locking portion 10 has a frustoconical shape in which the distal end outer diameter d is smaller than the base outer diameter D. If the distal end is fitted into the hole 2 and pressed, the slit grooves 12, 12. The outer diameter of the stop portion 10 is reduced, and when the base portion passes through the hole 2, the locking pieces 13, 13... Are expanded outward so that the locking portion 10 is not detached from the hole 2. That is, the locking portion 10 is locked in the hole 2.
Therefore, the locking portion 10 can be fitted and locked in the hole 2 with one touch, and the suction sheets 1 and 1 on both sides can be easily connected.

図５は油吸着装置１４を示す他の実施例である。この油吸着装置１４は前記図２に示す油吸着装置の各吸着シート１ａ，１ａ・・・の下縁側に別の吸着シート１ｂ，１ｂ・・・を連結して構成している。すなわち、油吸着装置の吸着シート１ａ，１ａ・・・の下縁側穴２ａ，２ａ・・・に別の吸着シート１ｂ，１ｂ・・・の上縁側穴２ｂ，２ｂ・・・を連結具７，７・・・を介して繋いでいる。
図２に示す油吸着装置４では流出した油の吸着が十分でない場合、図５に示すように別の吸着シート１ｂ，１ｂ・・・を繋ぐことでより多くの油の吸着が可能となる。 FIG. 5 shows another embodiment of the oil adsorption device 14. The oil adsorbing device 14 is configured by connecting other adsorbing sheets 1b, 1b,... To the lower edge side of the adsorbing sheets 1a, 1a,. That is, the upper edge side holes 2b, 2b,... Of the other suction sheets 1b, 1b,. It is connected via 7 ...
When the oil adsorbing device 4 shown in FIG. 2 does not sufficiently adsorb the oil that has flowed out, more oil can be adsorbed by connecting different adsorbing sheets 1b, 1b... As shown in FIG.

この油吸着装置１４の場合においても、別に繋いだ吸着シート１ｂ，１ｂ・・・の下縁側の穴２ｂ，２ｂ・・・を連結具７，７・・・を介して繋ぐことで、隣り合う吸着シート１ｂ，１ｂ・・・に形成される空間の拡大を抑制することが出来る。   Also in the case of this oil adsorption device 14, adjoining adsorbing sheets 1b, 1b,... Are connected by connecting holes 2b, 2b,. The expansion of the space formed in the suction sheets 1b, 1b... Can be suppressed.

一方、上記吸着シート１，１・・・の各コーナーに設けている穴２，２・・・を利用して、複数枚を重ねた油吸着装置として構成することも可能である。これも、全ての吸着シート１，１・・・を２枚重ね形態とする必要はなく、例えば１枚おきに２枚重ね構造とすることが出来、その形態は自由である。   On the other hand, it is also possible to configure an oil adsorbing device in which a plurality of sheets are stacked by using the holes 2, 2... Provided in the respective corners of the adsorbing sheets 1, 1. Also, it is not necessary to make all the adsorbing sheets 1, 1... Into a two-ply form, for example, every two sheets can be made into a two-ply structure, and the form is free.

一口に油と言ってもその種類は色々あり、例えばＡ重油、Ｂ重油、Ｃ重油、灯油、又は機械油などであるが、本発明の天然繊維カポックを主体とした吸着シートは、上記油の種類が如何様であってもその吸着力は従来の吸着シートに比較して数倍以上の効果を発揮することが出来る。   There are various types of oil even if it is a bite, such as A heavy oil, B heavy oil, C heavy oil, kerosene, or machine oil, but the adsorbing sheet mainly composed of the natural fiber kapok of the present invention Whatever the type, the adsorbing power can exhibit an effect several times that of the conventional adsorbing sheet.
