Abstract

PURPOSE:To recover crude oil, etc., by a surface boat by introducing oily water from the gate at an intake provided on the front of 2 hull utilizing the head due to the hull weight without any energy, separating oil from water by gravity and discharging the water. CONSTITUTION:A gate is closed when a boat 8 is unloaded. The gate 9 is slid down when a oil-water mixture is introduced to open the intake, and the oily water flows in torrentially since the boat is empty and the head 10 to the bottom is high. The gate 9 has to be slid up inversely proportional to the sinking of the hull, the sliding up rate is almost equal to an increase in the draft, the draft increases gradually, the gate 9 ascends, and finally the intake is closed while leaving buoyancy. Oil and water are separated spontaneously after a while, and oil is accumulated at the upper part and the water at the lower part. A water pump 6 is driven to discharge the bottom water, and hence the oil bottom surface is lowered in the boat and reaches immediately above the pump. When a 10,000-ton-class boat is actually used, the charge and discharge are simultaneously and successively carried out, and a large amt. of oil is rapidly recovered.

[Detailed Description of the Invention] Industrial application field This method is mainly for recovering oils leaked to the sea such as damage to tankers and crude oil leaked to the Persian Gulf in the Middle East war. Accidentally spilled oil,
It is a method that can be easily recovered even with water oil. Exceptionally, red tides on the sea are also possible, which is an application problem. Conventional technology Many crude oil spilled into the Persian Gulf in the Middle East War last year.
If the members of the Japanese oil industry are struggling to collect this, it was also published in the Asahi Shimbun on May 25 this year, but this method is truly poor and childish, so I can not see it. That is the method that makes you even suspicious of the oil recovery technology of Japan, which is said to be a developed country. Since I'm a member of the Japanese oil industry, I think it's probably a top-class technology, but I don't know much about it, so here are some of them for reference.
Please see the cutout of this newspaper attached for reference. "The hardest part was changing the quality of crude oil.
The oil from which the volatile oil has flown becomes clay-like and is 30
It had a layer of ~ 40 cm. The viscosity changes even if the temperature changes throughout the day. The prepared recovery pump has no teeth.
Along with the Philippine workers, I went to the black sea together, scooped up a lump of oil by hand, and plunged it into a pump. Since I didn't have a dipper, I switched to a screw pump for civil engineering work, and finally 1 per
I was able to absorb 10 tons of oil per hour. I'll continue, but I will attach a newspaper. From the above articles, there seems to be no other good law, and I do not know. The following method is a conventional technique that I considered when a tanker accident occurred off the coast of Canada. We hope that the present invention will be used in the Persian Gulf if possible. Problems to be Solved by the Invention (1) Utilizing the natural separability of oily water. There is a special power that can be said to be a separating power rather than a separating property, and this should be fully utilized for research. Considering the natural separating power of oil a. There is a difference in specific gravity between water and oil. B. Both water and oil have cohesive force and surface tension. Crude oil has particularly high adhesive strength and cohesive strength. C. Other than that, various things can be considered by studying the electric force and the function of molecules, but these are also used for research and synthesis. (2) It is not a childish or inferior method as described above, but a larger, easier and mechanical method. (3) In particular, make full use of the difference in specific gravity and separation force. (4) Since it is sticky, a water wall (or curtain) should be placed between the equipment and the hull so that it will not come into direct contact as much as possible. (5) For the intake of oil and water, consider the weight of the hull and use the natural inflow (intake) method of utilizing the head, and also by utilizing the forward force of the ship,
Do not waste energy by not pumping. (6) Since a large amount of waste water is needed during oil recovery, stop the propeller of the ship and use this drainage for propulsion. Means for Solving the Problems (1) A tanker is partially modified and used. It can be a used item. (2) Initially, experiments will be conducted with 100 tons class, but the experiments will be repeated and the size will be increased one after another, aiming at 10,000 tons class recovery vessels. (3) There are many problems such as the special opening / closing device as described in the embodiments at the front part of the ship and the oil / water inlet, and there are many problems such as the oil level cutting problem. For the most part, these belong to the design and production area. Operation (1) First, the principle is briefly explained. Figure 1. As shown in, the container 2 is submerged in the sea where the crude oil floats. Since the intake port 3 is located at the upper part and is slightly lower than the others, there is a drop if it is submerged below the oil water surface, so that the oil water naturally flows into the container vigorously. 1 is oil-water mixture. At this time, it is assumed that the container is fixed at a certain depth. That is, it may be considered that the ocean floor has been reached. If left as it is for a while, the oil water becomes full, that is, it becomes equivalent to the oil level at sea. If left as it is or left for a while, the oil 4 is naturally separated by the oil-water separation force, and the oil 4 accumulates in the upper part and the water 5 accumulates in the lower part. When the lower drainage pump 6 is driven to discharge water from this, the front liquid level in the container drops, causing a difference from the liquid level above the sea, and the oil water on the sea surface flows into the container again. This oily water is also separated in the same way, and the water collects downward, so the drainage pump
After all, it can be operated continuously, and when continuously operated, the oil bottom gradually descends and finally reaches the upper part of the drainage pump. At this time, it will be full. In this continuous operation, it is easily assumed that oil and water separation will be performed to the extent that it matches the inflow and the discharge at the same time, considering a large tanker container without considering a small container. .. It is considered that the liquid 7 from the upper part of the pump to the bottom part has a high degree of oil-water mixing, but since it is also sufficiently separated if left for a day, the water intake may be lowered and discharged the next day (2) Water pump Considering the above, since the inflowing oil and the oil level on the container are almost the same, the pressure difference between the inside and outside of the pump is almost zero, and little energy is required to discharge the water. Good. In other words, it is a great feature of the fact that it requires very little energy. The above is the principle, but in the case of a ship, when oil water flows in, the water line decreases (the water flow becomes large), so the method and way of thinking are slightly different. This will be described in the next section. Example (1) Generally speaking, a tanker is a vessel with an oil / water inlet at the front of the vessel and a drainage pump at the bottom of the rear. (2) FIG. In the explanation, it is assumed that 8 is a ship, the gate 9 is closed when the ship is empty, and the oil surface ship is in the middle level of the gate 9. When oil-water mixture is to be introduced, the gate 9 is slid down and the intake is opened. (Perform hydraulic operation, etc.) At this time, since the inside of the ship is empty and the drop 10 with the bottom is large,
Oil water flows in vigorously. (Lower layer is water layer) When oily water flows in, the hull loses its buoyancy and gradually sinks. If it is left as it is, the upper part of the intake will enter the oil layer, and finally the water will flow into the water layer, and it will sink more and more and eventually sink. Therefore, it is necessary to gradually raise the intake gate 9 in inverse proportion to the hull sinking. The uplift value is almost equal to the increase in draft value. The thickness of the oil-water layer at the inflow port is preferably as constant as possible, but the thickness of this layer is set to a certain thickness H. H is said to have overlapped oil and water at the oil / water inlet (intake), and the water layer is a layer for preventing the oil from directly contacting the hull or wall of the inlet, which may be minimal, At sea, etc., a considerably large wave is possible,
Since the hull is swaying forward, it is necessary to consider this and the vertical movement of the waves to make it considerably large. That is, the oil layer through the water curtain. (Even if a little water is taken in, it does not become a big problem. Since it is discharged with a small pressure from the bottom) (3) Figure 3. Is an explanatory view of this intake relationship. As described above, if oil water intake is continued, the draft value gradually increases, and the gate 9
Finally, the intake is closed, leaving buoyancy. At this time, the ship was full and the upper space was
It is a buoyancy space 7. Thus, after a while,
Oil water naturally separates and oil collects at the top and water at the bottom.
At this time, if the drainage pump 6 is driven to drain the bottom water,
The oil level in the hull descends, but the ship becomes lighter by the amount of water it drains, so it floats that much. When the gate 9 is opened again, the marine oil water flows in and the water mainly collects at the bottom, so that the oil level inside the ship is pushed up and the drainage pump can be driven again.
Drain again. This relationship is as described in the principle. Repeatedly, the oil bottom gradually descends inside the ship, and finally reaches the position just above the drainage pump. This drainage pump can minimize this residual water by providing a recess in the bottom of the ship. Also, this pump is equipped with backflow prevention. This explanation was given separately to make the theory easier to understand, but in reality, considering a 10,000-ton class ship, even if inflow (intake) and discharge are performed simultaneously and continuously, , Same as repeat, in reality, uptake,
The water is drained at the same time, and the bottom of the oil in the ship is gradually lowered until it becomes full. (4) The drainage pumps 6 are attached to the bottom of the ship, on the left and right of the rear part, and can discharge a large amount of water for convenience of design efficiency.
Figure 4. This can be used for hull propulsion as shown in. At this time, the ship's own propulsion unit does not have to be used, which saves energy and also steers, for example.
If you squeeze the right side of the discharge water (make it smaller) and increase the left side,
The ship turns to the right, and to the left if turned the other way around. This is done in collaboration with the rudder. At this time, one propeller on the hull may be attached at the center, or two propellers may be attached above the pump. (5) When the hull is large, the draft is relatively small, but in the case of a small boat, the capacity is small, so it is considered that the draft is large. As shown in, the gate may be divided into several stages such as A and B, and this is adopted. In this case, first, A is slid down to open, oil water flows in, and A is gradually raised contrary to the sinking of the ship (this is the same as the previous explanation). If the upper end overlaps B, then B is lowered and gradually. Raise it to the upper string 11
If it overlaps, fill it up. Such a method is also an example. (6) The thickness of crude oil was generally thought to be about a few centimeters, but according to the newspaper mentioned above, it is 30 to 40 centimeters, so the intake width is not constant, and it narrows depending on the thickness. The mechanism is such that it can be expanded or widened. When the oil layer is thin and less viscous, the intake is also expanded to near the side of the ship, and the forward power of the ship is also used to the maximum, and oil and water are scooped with both arms for intake. (7) According to the newspaper, it is surprising that the crude oil thickness may be unexpectedly thick, but in such a case, the intake naturally must be narrowed and the crude oil seems to have a strong viscosity. At the oil layer incision part, it is considered that crude oil adhesion will gradually increase, and it will increase in size one after another, and it will be a considerable pressure burden. Therefore, incision is made as follows. Figure 6. As shown in Figure 12, if you take a vessel 12 and eject a high pressure water zone from the spout 13, the oil layer can be easily cut open, and some reflected water will form a water curtain between it and the oil. Prevent direct contact. or,
Weakly pressurized water is discharged from the 14th hole and made to flow, and like the above, a water curtain is created between the equipment and the hull to prevent sticking. This is strong and weak, you may send water from two systems, but if you do as shown in the figure,
Even if water is fed from a single line under high pressure, the purpose will be fully achieved. That is, although 13 is an injection port, it is lengthened vertically and its length can be adjusted according to the oil layer thickness. If the tip b is narrow and the water inlet a is wide, the jetted water can give strong kinetic energy and jet strongly (it is a general principle). However, if this is reversed (ie, the outlet is large and the inlet is small), as in the case of 14 holes, a weak jet is obtained. By appropriately using this relationship, the desired strong and weak fountains can be obtained freely. In order to adjust the vertical length (width) of the oil layer in accordance with the thickness of the oil layer, 15. As shown in, a vertically moving piston is used. In addition, this device is shown in FIG. In the case of a single gate like the above, it can be directly attached to both ends of the upper part, but Fig. 5. In the case of a multi-stage gate, as shown in, the bottom is floated so that the relationship with the oil surface is appropriate, and it is treated as a separate device. (8) The mechanism for moving the gate up and down (generally hydraulic pressure is considered), the problem of watertightness, the problem of hull reinforcement,
There are many problems because it is a new invention, such as the case of cutting the oil layer,
These are problems of design and manufacture, and the detailed description is omitted, and the mechanism is in accordance with the purpose of the invention. Effects of the invention (1) It is much simpler than the conventional method. (2) It is possible to collect a large amount of oil immediately. (3) No human or mechanical energy is required because the natural separation property of oil water is used. (4) In the case of oil and water intake, a drop due to the weight of the ship is used, and the forward force of the ship forward is added to this to use the natural inflow method of oil water, so no special energy is required for intake. (5) Since the discharge pump contains almost no oil and is close to seawater, it requires less energy than directly recovering highly viscous substances such as crude oil with a pump. (6) Even if the drainage pump discharges from the bottom, there is little difference between the oil level on the sea and the oil level on the ship, so there is little difference in the internal and external pressures, and a pump with a large capacity can operate with the same energy. That is, compared to ordinary ship bottom drainage, a large amount of water can be discharged with a small amount of energy. Large volume wastewater is associated with large volume oil recovery. (7) The pump discharges a large amount of water, which can be used for propulsion and steering of the hull and can be utilized. (8) Although the present invention has been described mainly for the purpose of recovering marine crude oil, oil and crude oil can be recovered on lake water or rivers, and exceptionally even red tides generated at sea can be recovered. It is a matter of application.
