Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority under 35 U.S.C. .sctn. 119
to Korean Patent Application No. 10-2018-0019563 filed on Feb. 19,
2018 in the Korean Intellectual Property Office, the disclosure of
which is incorporated herein by reference in its entirety.
TECHNICAL FIELD
[0002] The present disclosure relates to a fence having a
hydrophilic material, and more particularly, a fence having a
hydrophilic material in which a hydrophilic oil separating material
is used for a float and a skirt that constitute the fence so that
the entire fence has a function to allow water to penetrate while
disallowing oil to penetrate, thereby stably trapping oil or
hazardous & noxious substances in water quickly and reliably
even at areas with strong tidal currents of high velocity flow or
high waves.
BACKGROUND
[0003] When oil or hazardous & noxious substance (HNS) spill
accidents occur in seas and rivers, oil or HNS spreads out rapidly
on the surface of the seas and rivers, causing serious
environmental pollution.
[0004] Accordingly, when oil or HNS spill accidents occur, it is
important to remove quickly.
[0005] In general, when oil is spilled on seas or rivers, after
flows of marine currents are calculated and a primary spill barrier
is installed by installing an oil fence, an emulsifying agent is
sprayed to cause oil contained and collected by the oil fence to
sink in deep water, or oil is collected using oil collection
equipment such as an oil skimmer and absorbent fabrics.
[0006] However, in the case of conventional oil fence, at areas
with strong tidal currents or high waves, the fence often gets
unbalanced due to the water pressure and its effect sharply
reduces, and thus the conventional oil fence is difficult to
use.

[0030] As shown in these drawings, the fence 10 having a
hydrophilic material according to an embodiment of the present
disclosure includes a float 11 that floats in the water, and a
skirt 12 coupled to at least one of top and bottom of the float 11,
wherein at least one of the float 11 and the skirt 12 is made of a
hydrophilic material that allows for selective penetration of a
hydrophilic fluid, or has a surface to which a hydrophilic
separation membrane made of a hydrophilic material is coupled.
[0031] In conventional oil fence, as shown in FIG. 1, when strong
tidal currents occur, or the oil fence (a float 701 and a skirt
702) is towed at high speeds to collect oil, the oil fence (the
float 701 and the skirt 702) gets damaged or unbalanced due to a
strong water pressure applied to the oil fence (the float 701 and
the skirt 702), resulting in oil spills, but according to
embodiments of the present disclosure, these problems can be
solved.
[0032] Hereinafter, each element will be described in detail.
[0033] The float 11 is formed to float on the surface of water, and
may be manufactured in the shape of a cylinder and a polygonal
pillar, and the length of the float 11 may vary as well.
[0034] Of course, to improve the buoyancy of the float 11, for
example, air pocket of rubber or vinyl may be installed inside or
outside of the float 11.
[0035] The float 11 is made of a hydrophilic material that allows
for selective penetration of a hydrophilic fluid, or has a surface
to which a hydrophilic separation membrane made of a hydrophilic
material is coupled.
[0036] Here, the hydrophilic material includes natural fibers
(cotton, pulp, cellulose, rayon), polymers (acrylic, polypropylene
(PP), polystyrene (PS), polyurethane (PU)), or metals.
[0037] Meanwhile, the hydrophilic separation membrane made of the
hydrophilic material may have, for example, a porous material
surface-treated to have hydrophilicity.
[0038] Furthermore, the hydrophilic separation membrane may have
pores of 2 .mu.m to 500 .mu.m.
[0039] Additionally, the hydrophilic separation membrane may have,
on the surface, nano protrusion structures having the diameter of 1
to 100 nanometers made of metal or polymer such as polyurethane,
polypropylene, polystyrene and acrylic fiber.
[0040] Meanwhile, the hydrophilic separation membrane may be formed
with the thickness of 10 .mu.m to 1 cm.
[0041] The hydrophilic separation membrane may be formed in
multiple layers.
[0042] Subsequently, the skirt 12 is coupled to at least one of top
and bottom of the float 11, and the drawings show an example in
which the skirt 12 is coupled to the bottom of the float 11.
[0043] Of course, the skirt 12 is also made of a hydrophilic
material that allows for selective penetration of a hydrophilic
fluid, or has a surface to which a hydrophilic separation membrane
made of a hydrophilic material is coupled.
[0044] Meanwhile, a weight member may be coupled and fixed to the
bottom of the skirt 12, and the weight member may be fixed into a
coupling hole formed on the bottom of the skirt 12, or may be
connected and fixed to the bottom of the skirt 12 with a fixing
member such as a rope or a hanger loop.
[0045] Additionally, a reinforcing material may be coupled to at
least one of the float 11 and the skirt 12, and the reinforcing
material performs a function to reinforce the strength of at least
one of the float 11 and the skirt 12.
[0046] For example, the reinforcing material may be formed covering
the entirety with a material such as a glass fiber mesh, or may be
formed in the shape of a band of PP, PC and PE.
[0047] Meanwhile, the fence having a hydrophilic material according
to an embodiment of the present disclosure includes a support 401
composed of a plurality of frames coupled to support the surface of
at least one of the float 11 and the skirt 12 in order to reinforce
the strength.
[0048] Of course, as shown in the drawings, the support 401 may be
provided to support both the float 11 and the skirt 12, and may be
provided to support only one of the float 11 and the skirt 12.
[0049] The support 401 may be made of, for example, vinyl, fabric,
and metal.
[0050] Meanwhile, in case that the fence having a hydrophilic
material according to an embodiment of the present disclosure has a
surface to which a hydrophilic separation membrane made of a
hydrophilic material is coupled, the float 11 includes an inner
floating body 403 continuously extending in spiral shape.
[0051] The inner floating body 403 continuously extends in spiral
shape, and in other words, the inner floating body 403 is
manufactured in the shape of a coil.
[0052] The inner floating body 403 is designed to assist in the
maintenance of the circular shape of the float 11 while preventing
a reduction in water penetration capability of the float 11 as much
as possible.
[0053] Additionally, in case that the fence having a hydrophilic
material according to another embodiment of the present disclosure
has a surface to which a hydrophilic separation membrane made of a
hydrophilic material is coupled, the float 11 includes a plurality
of tube bodies 501 spaced apart from each other, and at least one
disk member 503 through which the plurality of tube bodies 501 is
each coupled to hold the plurality of tube bodies 501 together.
[0054] The plurality of tube bodies 501 is spaced apart from each
other, and for example, air is injected into the inner part of the
tube bodies 501 to provide buoyancy to the float 11.
[0055] Meanwhile, one end of the plurality of tube bodies 501 may
be connected to each other as shown in the drawing.
[0056] The disk member 503 holds the plurality of tube bodies 501
together, and the disk member 503 has through-holes through which
the tube bodies 501 are coupled.
[0057] The disk member 503 may be made of, for example, plastic,
metal and rubber.
[0058] Additionally, in case that the fence having a hydrophilic
material according to still another embodiment of the present
disclosure has a surface to which a hydrophilic separation membrane
made of a hydrophilic material is coupled, the float 11 includes an
inner floating body 603 formed of a tube including a plurality of
through-holes 601.
[0059] For example, the inner floating body 603 may be formed in
the shape of a circular inner float with inner holes in honeycomb
structure, and this structure allows water to smoothly penetrate
the inner floating body 603.
[0060] Of course, after the inner floating body 603 is coupled to
the float 11, air may be injected into the inner floating body 603
to maintain the shape and the strength of the inner floating body
603.
[0061] Additionally, in case that the fence having a hydrophilic
material according to further another embodiment of the present
disclosure has a surface to which a hydrophilic separation membrane
made of a hydrophilic material is coupled, the float 11 includes a
plurality of tube bodies 701 arranged in parallel, and a coil
member 703 into which the plurality of tube bodies 701 is inserted
so that the plurality of tube bodies 701 is supported.
[0062] The plurality of tube bodies 701 is provided in parallel,
and for example, air is injected into the inner part of the tube
bodies 701 to provide buoyancy to the float 11.
[0063] The coil member 703 is provided to support the plurality of
tube bodies 701 inserted therein, and for example, the coil member
703 is formed in the shape of a spring made of metal, plastic and
carbon.
[0064] The provision of the coil member 703 prevents the shape of
the float 11 from being damaged by an external force.
[0065] A general oil fence with no separation membrane made of a
hydrophilic material is subjected to the pressure of about 800 kPa
by the flow rate of 1 knot, but as shown in FIG. 8, in the fence 10
having a hydrophilic material according to the embodiments of the
present disclosure, the pressure is about 160 kPa when the distance
of fabric in the hydrophilic separation membrane is 10 micrometers,
and the pressure is about 3 kPa and about 1 kPa when the distance
of fabric is 20 to 100 micrometers as commonly used, and thus it
can be seen that the pressure reduces sharply.
[0066] It can be seen from the following [Table 1] that under the
condition of 1 knot, Comparative Examples 1 and 2 are subjected to
the pressure above the critical point, 110 kPa, whereas Examples 1
to 5 are subjected to the pressure of 24% or less of the critical
point, 110 kPa.

[0067] As described hereinabove, according to an embodiment of the
present disclosure, as the fence is made of a material that allows
water to penetrate while disallowing oil to penetrate, there is an
effect in collecting oil or hazardous & noxious substance (HNS)
quickly and efficiently while minimizing the pressure caused by
water.
[0068] Additionally, even when a strong water pressure acts on the
fence, for example, strong tidal currents occur and the fence is
towed at high speeds to collect oil, the water pressure applied to
the fence reduces due to water penetration, so there is an effect
in preventing oil spill phenomena caused by damage or unbalance of
the fence.
[0069] Although the foregoing statements describe that all the
elements constituting the embodiment of the present disclosure are
combined into one or work in combination, the present disclosure is
not necessarily limited to the disclosed embodiment. That is, the
elements may be selectively combined into at least one within the
intended scope of the present disclosure.
[0070] It should be understood, unless otherwise stated to the
contrary, the terms "including", "comprising" or "having" as used
herein specify the presence of mentioned element, but do not
exclude the presence or addition of one or more other elements.
Unless otherwise defined herein, all terms used herein including
technical or scientific terms have the same meaning as commonly
understood by those having ordinary skill in the technical field
pertaining to the present disclosure. The commonly used terms such
as those defined in dictionaries should be interpreted as being

unless explicitly defined herein, they are not interpreted in ideal
or excessively formal sense.
[0071] The foregoing description is provided to describe the
technical spirit of the present disclosure by way of example only,
and it is obvious to those having ordinary skill in the technical
field pertaining to the present disclosure that various changes and
