Abstract

PROBLEM TO BE SOLVED: To provide an oil fence which has a float bag hardly punctured, by which oil absorption quantity can be increased, oil leakage can be reduced, it can be less apt to be bulky before use, and further the incineration amount can be decreased by installing a floating bag in a cylindrical bag formed by a lipophilic deformed fibrous cloth, the deformation degree of which is specified. SOLUTION: A floating bag 12 made of polyethylene, which is swollen by injecting gas is installed in a cylindrical bag 11 formed by a lipophilic deformed fibrous cloth, which has the deformation degree expressed by the equation: K=L(4πS)<1/2> ranging from 1.1 to 10. Where, S indicates the sectional area of the fiber forming the cloth, and L indicates the average value of total circumferences of fibers forming the cloth. Further a skirt 13 formed by the same non-woven fabric as that of the cylindrical bag 11 is fitted to the outer peripheral surface of the cylindrical bag 11. Compressed air or the like is injected into the floating bag 12 from a filling port 12a, and when the bag is thrown down on the surface of the sea where oil flows out, an oil absorption type oil fence 10 is floated on the water surface by the floating bag 12 to interrupt outflow of oil and simultaneously absorb oil floating by the cylindrical bag 11 made of lipophilic raw material.

Description of the Related Art An oil fence literally aims at a simple wall function for preventing external diffusion of oil spilled on a water surface, for example, the sea surface, and is a block-shaped styrofoam body, a polyethylene foam body, or a foamed foam. A long articulated fence is formed by connecting buoyancy materials such as urethane bodies in a line with a string or the like.

を潜って外部へ流出する恐れがある。When an oil spill accident occurs at sea, the site of the oil spill is surrounded by an oil fence to prevent the oil from spreading further. In order to recover the oil, the oil is sucked up by another means, for example, a suction recovery device, or the mat-like material is thrown to the sea surface to be absorbed. However, there is a risk that oil may flow out of the gap of the oil fence during recovery, get over the oil fence under the influence of waves, or may flow out under the fence.

One described in Japanese Patent Publication No. 188 is known. Both prior arts are oil adsorption type oil fences having both a fence and an adsorbent. These are basically made into a fence with a block-shaped buoyant material, for example, a styrofoam body, a foamed polyethylene body, a urethane foam body or the like as a core, and the periphery thereof is covered with a nonwoven fabric-shaped oil adsorbent. .

点を増長させる結果になっている。[0005] In such an oil-absorbing type oil fence of the prior art, a cylindrical bag made of a lipophilic material is usually provided by processing a synthetic resin fiber material having a circular cross section. There is a problem that the amount of oil adsorbed as a material is relatively small. In addition, since the conventional oil absorption type oil fence has a structure in which the block-shaped buoyancy material is covered with the nonwoven fabric as described above, the disadvantage of the oil fence is increased.

大している。That is, an oil fence having a block-shaped buoyancy material is easily bulky, requires a large storage space, is inconvenient to transport, and has a reduced function due to oil stains or damage on the surface. However, repair and reuse are difficult and must be incinerated, which may cause environmental problems. On the other hand, an oil-absorption type oil fence in which a block-shaped buoyancy material is covered with a nonwoven fabric is bulkier than this simple oil fence because of the presence of the oil-absorption material in addition to the block-shaped buoyancy material. In addition, since it has a rough structure, it is easily deformed, and storage and transportation are more inconvenient and costly. Moreover, when the oil adsorbent on which the oil is adsorbed is collected, friction is large because the buoyancy material at the center has a foamed structure. As a result, it becomes difficult to remove the buoyant from the adsorbent, and ultimately this oil adsorbent must also be incinerated together with the buoyant. It is increasing by a certain amount.

る。SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and can increase the amount of oil adsorbed as an oil adsorbent, has less oil leakage, and is bulky until use. This makes it possible to transport a larger amount of oil-absorbing oil fences on a single ship, and has a relatively small storage space and low cost. It is an object of the present invention to provide an oil-absorbing type oil fence in which a floating bag body is unlikely to be punctured by collision of an object or the like. In particular, it is an object of the invention of claim 2 to provide an oil-absorbing oil fence that has high lipophilicity and high bonding strength of constituent fibers of a fabric and is hardly deformed or damaged even when oil is absorbed. .

An oil-absorption type oil fence characterized in that a floating bag body that expands by injecting a gas is mounted therein. K = L / √ (4πS) where S is the cross-sectional area of the fiber constituting the fabric, and L is the average value of the total circumference of the fiber constituting the fabric.

The boom can be transported to the oil spill site. In addition, the storage space can be made relatively small. Furthermore, since a relatively expensive foamed resin is not used for the float material of the oil absorption type oil fence as in the related art, the cost can be reduced. And after collection, the gas can be released from the floating bag to make it compact, so even when disposed of,
This is advantageous for transportation and handling. In addition, since the floating bag body is structured so as to be included in the tubular bag made of fabric, there is little risk of puncturing and sinking due to collision of an object or the like.

Since it is constituted by a cloth mainly composed of a lipophilic modified fibrous material which is 10, the contact area with oil is large with respect to a cloth such as a nonwoven cloth made of ordinary lipophilic circular cross-section fibers, Excellent oil absorption. In addition, it is possible to keep holding the oil even if it is shaken by the waves for a long time, and it is difficult for the oil to flow out of the oil fence. Here, the degree of irregularity K
Is represented by the above equation and is equal to a value obtained by dividing the total perimeter of the fiber cross section by the perimeter of a circle having the same area as the fiber.

When the cross section of the fiber is complicated, for example, it is determined by the following method. That is, 50 fibers constituting a nonwoven fabric or the like are randomly taken out, the fiber bundle is cut in a direction perpendicular to the fiber axis, and a cross-sectional photograph is taken with a microscope. S is obtained by tracing the obtained fiber cross section on paper, cutting the paper into a traced shape, and dividing the total mass of the cross section by the mass per unit area of paper and the total number of fiber cross sections (number). . As a method of obtaining L, as shown in FIG. 7, the obtained fiber cross section is traced on a graph paper, and an arbitrary region including all the fiber cross sections traced on the graph paper is set. Here, using geometric establishment theory (integral geometry),
It is determined by using the following equation. L = πnM / 2N
T Here, n is the total number of intersections between the grid lines of the graph paper and the perimeter of the traced fiber cross section, M is the area of the set area, N is the total number (number of fibers) of the fiber cross section, and T is the set area. This is the sum of the lengths of the grid lines of the graph paper (not including the set area lines).

ない。The degree of irregularity is from 1.1 to 10, and if it is less than 1.1, it will not be possible to obtain an effective oil adsorbing property, and if it is shaken for a long period of time, it will not be able to keep the oil. If it exceeds 10, sufficient strength is not obtained in the fiber itself, and when the oil is adsorbed, the fiber is detached from the fabric constituting the fiber and is easily broken. FIG. 6 shows an example of a cross-sectional shape of an irregular fibrous material having an irregularity of 1.1 to 10. These irregular cross-sections can be formed by changing the shape of the spinneret, foaming, or the like, and as shown in FIG. 6, are arcuate, have irregularities in the surface shape, are porous, have various shapes. Is possible. The average cross-sectional area of the lipophilic fibrous material is 0.001 to
Preferably 1 mm 2, is less than 0.001 mm 2, greater fiber density, i.e., the oil gap which adsorbs is too small a suction fiber becomes poor, while when it exceeds 1 mm 2,
The contact area with oil is small, and effective oil adsorbability cannot be obtained.
