Description

Fluid spill oil recovery device {OIL RECOVERY APPARATUS}

The present invention relates to a fluid effluent oil recovery device, and more particularly, to an effluent oil recovery device capable of instantly and automatically recovering oil when oil spills into the sea or river, as well as performing oil refining at once.

Oil consumption is increasing due to recent industrial development, and as a result, oil spill accidents in which oil is leaked into the sea or river due to an overturning accident of an oil tanker or tanker in the process of transporting oil are increasing.

Such an oil spill accident can cause serious environmental pollution problems in the surrounding environment because a large amount of oil is discharged from the sea or river at once and spreads rapidly to a wide area.

In addition, although it is said that the oil spilled into the sea or river takes several months to several years to be purified, it is actually very difficult to completely remove the oil in the sea, and there is a problem that it is not easily purified even after several decades. As such, oil spills in the sea or rivers cause serious damage over a long period of time, so they must be removed as soon as possible at the same time as oil spills.

In general, the method of removing oil spilled from the sea or river is performed by first preventing the spilled oil from spreading to an oil fence, and then performing a control operation.

The control method is a physical treatment method that absorbs the oil that forms a film on the water surface with an oil absorbent or removes the oil floating on the surface with an oil absorber. There are chemical methods that prevent the mixed mass from sinking to the seabed, and biological methods that allow marine microorganisms to break down oil components.

However, all of these methods are suitable for the use of follow-up treatment in a situation where an oil spill has occurred and spread to the surroundings. There is a limit to using it as an immediate response measure to prevent it.

The present invention has been devised to solve the above problems, and it is to provide a spilled oil recovery device capable of preventing marine pollution through an active initial response immediately after an oil spill occurs in the ocean or river.

In addition, the present invention can minimize the diffusion of oil to the lower part of the oil fence or over the oil fence that occurs frequently according to the flow of seawater around the skirt attached to the existing oil fence by improving the configuration that serves as the existing oil fence.

1 and 3, the spilled oil recovery apparatus 1000 according to an embodiment of the present invention is a device that can be installed in all offshore facilities and ships, and is a device that can be operated independently of the ship. The spilled oil recovery device 1000 is a batch processing device that collects and refines oil spilled into the sea or river. The spilled oil recovery device 1000 may include an oil recovery unit 100 , a main body 200 , and a ballast tank 300 .

The oil recovery unit 100 serves as an inlet of the automatic oil recovery device 1000 , and serves to collect and recover oil leaked into the sea or river. The oil recovery unit 100 is to be less affected by the oil diffusion prevention unit 110 that prevents the oil spilled into the sea or river from being diffused, the water pipe 120 through which seawater flows and flows, and waves. It may include a wave suppressor 130 .

The oil diffusion prevention unit 110 serves as a kind of fence to prevent the oil spilled from the sea or river from spreading. The oil diffusion prevention unit 110 is configured as a pair facing each other in a 'Y' shape and may be fastened at positions on both sides of the body unit 200 .

The oil diffusion prevention part 110 is located between the key part (rudder part, 111) for adjusting the direction, the fastening part 113 fastened to the main body part 200, and the key part 111 and the fastening part 113, so that the key part ( The extension part 112 connecting the 111 and the fastening part 113 may be formed. Here, the key part 111 may further include a towing ring that allows the spilled oil recovery device 1000 to be towed to a ship.

The oil diffusion prevention unit 110 may be submerged in about half of the water surface. Accordingly, the oil diffusion prevention unit 110 may be made of a material capable of having buoyancy or may have a structure capable of maintaining buoyancy. The cross-section of the oil diffusion prevention unit 110 may have a circular shape with reference to an enlarged view of part A of FIG. 1 . In addition, the oil diffusion prevention unit 110 may have a structure in which the upper part 110a and the lower part 110b are separated. In more detail, air may be injected into the upper portion 110a of the oil diffusion prevention unit 110 , and a liquid such as air or water may be filled in the lower portion of the oil diffusion prevention unit 110 .

The water pipe 120 is a pipe through which seawater flows and may be mounted under the oil diffusion prevention unit 110 . In this case, the diameter of the water pipe 120 may be smaller than the diameter of the oil diffusion prevention unit 110 . Such a water pipe 120 may form a double bottom construction with the oil diffusion prevention unit 110 . Accordingly, the spilled oil recovery device 1000 according to an embodiment of the present invention is provided with a water pipe 120 through which seawater flows, so that even when there is a severe wave due to bad weather conditions, the oil is stably supplied without departing from the sea level. can be recovered

The wave suppression unit 130 may be disposed vertically or horizontally between the oil diffusion prevention units 110 configured in pairs to face each other in a ‘Y’ shape. In more detail, the wave suppression unit 130 is disposed on one side of one of the paired oil diffusion prevention units 110 and one side of the other oil diffusion prevention unit of the paired oil diffusion prevention unit 110 . Each can be connected. The wave suppression unit 130 may serve to prevent the oil diffusion preventing unit 110 from widening or narrowing due to waves, that is, waves. This wave suppression unit 130 may be configured in the form of a net (net).

As described above, in the oil recovery unit 100 of the spilled oil recovery apparatus 1000 according to an embodiment of the present invention, a skirt mounted on an existing oil fence is not disposed in order to prevent oil diffusion.

Referring to FIG. 2 , in general, when a skirt mounted on an oil fence is towed as shown in (a), there is a risk that oil blocked by the skirt may leak to the lower part of the skirt along the seawater. In addition, when the existing oil fence is towed as shown in (b), seawater and oil are wrapped by the skirt of the oil fence, and the overall configuration of the oil fence is submerged, so that the oil may flow outside the oil fence. In other words, both the water and oil around the skirt generate resistance and move up and down, which may further spread the oil. If the oil fence itself moves up and down irregularly by the skirt of the oil fence in this way, it may be difficult to separate and recover seawater and oil due to the difference in density. Accordingly, the oil recovery unit 100 of the spilled oil recovery device 1000 according to an embodiment of the present invention removes the skirt to reduce the resistance of water and oil generated around the skirt, which is a component of the existing oil fence, and removes the oil. By installing the water pipe 120 under the diffusion prevention unit 110, the oil diffusion prevention unit 110 and the water pipe 120 form a double low structure, so that the oil recovery unit 100 itself moves up and down irregularly due to waves. In order not to lose, it is further provided with a wave suppression unit 130 to more stably recover the oil spilled into the sea or river.

The body part 200 is connected to the oil recovery part 100 and introduces a case 210 that forms the exterior of the body part 200, and oil leaked into the sea or river to separate seawater and oil. 220 and the second oil separation unit 230 are provided, and a control unit (not shown) capable of operating and controlling each part of the spilled oil recovery device 1000 is provided inside the case 210 , and a power supply for supplying power A third oil separation unit that separates the seawater and oil separated twice by the supply unit (not shown), the first oil separation unit 220 and the second oil separation unit 230 into seawater and oil once again, seawater A storage unit for storing refined oil composed of only oil by discharging and a seawater discharge unit for discharging seawater separated by the third oil separation unit may be provided. The detailed configuration of the main body 200 will be described in more detail with reference to FIGS. 4 and 6 to 8 .

As shown in FIGS. 1 and 3 , the ballast water tank 300 is disposed on both sides of the main body 200 so that the body 200 is positioned at sea level due to an increase in weight due to oil inflow into the body 200 . to prevent immersion. Also, the ballast water tank 300 maintains a constant draft line position of the effluent oil recovery apparatus 1000 according to an embodiment of the present invention and can control the ballast water.

Accordingly, the spilled oil recovery apparatus 1000 according to an embodiment of the present invention stably collects and recovers the spilled oil when the oil leaks into the sea or river, and separates at least two seawater and oil from the main body 200 . It is possible to quickly respond to an oil spill accident by separating the oil over more than one turn so that only the oil is purified, so that an active initial response is possible.

It is a view for explaining a process in which the oil and the oil are separated, FIG. 6 is a view schematically showing the internal configuration of the body part of FIG. 4 , and FIGS. 7A to 8 are details of the second oil separation part among the internal configurations of the body part of FIG. 6 . It is a diagram for explaining the configuration and operation.

First, referring to FIG. 4 , the main body 200 of the spilled oil recovery apparatus 1000 according to an embodiment of the present invention may be supported by the oil recovery part 100 . The body part 200 may include a case 210 forming the shape of the body part 200 .

On the front portion of the case 210, the oil recovered by the oil recovery unit 100 is primarily separated from seawater and oil by a first oil separation unit 220 and a first oil separation unit 220. Primary and secondary by the second oil separator 230 and the first oil separator 220 and the second oil separator 230 that secondarily separates the oil separated from seawater into seawater and oil. An oil inlet 241 through which the oil separated from the seawater flows into the case 210 may be disposed.

The first oil separation unit 220 is a part that primarily separates the oil recovered by the oil recovery unit 100 from seawater, and may be formed of a first oil-water separation membrane. The first oil-water separation membrane is a membrane that passes seawater and separates only oil, and may be formed of a nano-filter or may have a form in which a plurality of pores are formed. As shown in FIG. 5 , the first oil separator 220 blocks oil leaking into the sea or river, and the clogged oil rotates in the seawater and swells over the surface of the first oil separator 220 upper part. The oil is introduced into the body 200 through the oil inlet 241 through the second oil separation unit 230 located in the .

The second oil separator 230 is a part that secondarily separates the oil primarily separated by the first oil separator 220 from oil and seawater, and may include a second oil-water separator. In this case, the shape and configuration of the second oil separator 230 may be different from those of the first oil separator 220 .

(232), the oil-water separation panel 233, the reverse rotation prevention stopper 234 and the rotating plate center rod 235 may be included.

The seawater inflow prevention unit 231 serves to control the inflow of a large amount of seawater entering the oil inlet 241 . The seawater inflow prevention unit 231 may be operated by the vertical movement of the waves in front of the oil inlet 241 . It is possible to prevent an excessive amount of seawater and oil from being introduced into the body portion 200 by the seawater inflow prevention unit 231 intermittently due to high waves. In this case, the seawater and oil flowing into the body 200 may be seawater and oil separated from seawater twice by the first oil separator 220 and the second oil separator 230 .

As shown in (a) of FIG. 8, the seawater inflow prevention unit 231 is a swim bladder (231a), a swim bladder (231a) and a gourd ( 231d) is connected to the swim bladder 231a by the connecting portion 231b and the connecting portion 231b, and is attached to the gourd (231d) and the gourd (231d) to prevent the inflow of a large amount of seawater, and the rotating portion 232 according to the rotational movement ) connected to the gear panel in the shape of a cogwheel and may include a rotation stopper 231c for rotating the rotating part 232 in a clockwise direction. At this time, the vertical movement of the swim bladder (231a) and the vertical movement according to the rotational movement of the gourd (231d) resulting therefrom may be inversely proportional. For example, as shown in Figure 7a, when the swim bladder (231a) is located at the bottom by the up-and-down movement of the waves, the gourd (231d) is directed upwards, and as shown in Fig. 7b, the swim bladder (231a) is a wave When it is located on the upper side by the vertical movement of the gourd (231d) is directed downward. More specifically, the oil inlet 241 of the main body 200 is disposed higher than sea level, and when the waves are low, the swim bladder 231a is located at the lower side and the gourd 231d is located at the upper side and the oil inlet port By opening the 241, a small amount of seawater can be introduced along with the oil spilled through the oil inlet 241, but when the waves are high, the swim bladder (231a) is located at the top and the gourd (231d) is located at the bottom and the oil By closing the inlet 241 , it is possible to prevent a large amount of seawater from flowing through the oil inlet 241 .

The rotating part 232 is connected to the seawater inflow prevention part 231 by the rotation stopper 231c, and can rotate clockwise around the rotating plate center rod 235. The rotating part 232, as shown in FIG. 8(b), rotates clockwise by the rotating plate center rod 235, and a plurality of spaces in which the oil-water separation panel 233 can be installed, that is, the porous , 232h) may include a cogwheel-shaped gear panel 232b disposed at both ends of the perforated rotating plate 232a and the perforated rotating plate 232a. At this time, the rotation stopper 231c of the seawater inflow prevention part 231 is located on the clockwise curved back surface of the saw blade of the circular gear panel 232b. It rotates in the direction and slides on the curved back of the saw blade, and during the downward movement of the swim bladder (231a), it rotates clockwise along with the gourd (231d) and is caught on the vertical surface of the saw blade to rotate the rotating part 232 clockwise. Due to the rotation of the rotating part 232 , the oil separated from the seawater flows into the body part 200 .

The oil-water separation panel 233 may be bound and attached to the perforations 232h formed in the rotary plate 232a. The oil-water separation panel 233 may be formed of a second oil-water separation membrane. The second oil-water separation membrane is a membrane that passes seawater and separates only oil, and may be formed of a nano-filter.

The reverse rotation prevention latch 234 is fixedly installed on the outer wall of the main body 200 , and serves to limit the rotation plate 232 from rotating in the counterclockwise direction, that is, in the reverse direction.

The rotating plate center rod 235 is connected to the rotating unit 232 and receives power from the power supply unit installed inside the main body when necessary according to the recovery work environment so that the rotating unit 232 can rotate in a clockwise direction. The rotating plate center rod 235 may include an inner body, for example, a rotating plate central rod shaft 235a connected to a motor. The second oil separator 230 may be fixed to the case 210 by the rotating plate center rod 235 .
