Description

Technical Field

[0001] The invention relates to the technical field of floating oil recovery, and in particular to a marine oil pollution separation collector. Background Art

[0002] In recent years, with the continuous development of the offshore oil industry and offshore oil transportation, the scale of offshore oil field exploration and development, submarine pipeline laying and crude oil transportation by cargo ships has also continued to expand, and the resulting marine oil spills and oil leaks have occurred frequently. After the oil enters the ocean, it will undergo changes such as diffusion, drift, evaporation, dispersion, and emulsification in the unique environment of the ocean, causing the water quality of seawater to deteriorate and causing ecological damage. In order to protect the marine environment and recycle available resources, a variety of oil spill recovery devices have been developed and applied. In the past, when oil spills occurred, oil booms and oil absorbent felts were generally used, which required a large amount of oil absorbent felts. In addition, ships and personnel had to guard around them throughout the process. After the oil absorbent felt was saturated with adsorption, it needed to be manually squeezed and de-oiled before it could continue to be used. The oil absorbent felts had to be replaced constantly, and the workers had high labor intensity and low efficiency. Summary of the invention

[0003] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a marine oil separation collector, which can effectively and continuously absorb the oil remaining on the sea surface, avoid the disadvantage that the oleophilic and hydrophobic sponge cannot continue to absorb oil after being saturated with adsorption, reduce the labor intensity of workers, and improve work efficiency.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions: and a tube connecting the discharging opening of the pump with a plug in the forward end of the crank case, said tube having a check valve in it at the bottom of the pump end, and said former tube which connects the pump to the oil drain plug, said former tube which connects the pump to the oil drain plug, and said former tube which connects the pump to the oil drain plug, said former tube which connects the pump to the oil drain plug, and said former tube which connects the pump to the oil drain plug, said former tube which connects the pump to the oil drain plug, and said former tube which connects the pump to the oil drain plug,

[0005] As a preferred solution, the oil collecting pipe includes an upper oil storage tank and a lower oil storage tank. The diameter of the upper oil storage tank is slightly larger than the diameter of the lower oil storage tank. The diameter of the piston is matched with the diameter of the lower oil storage tank, and the piston slides back and forth between the upper oil storage tank and the lower oil storage tank under the drive of the screw sleeve.

[0006] As a preferred solution, the two ends of the screw sleeve are slidably connected to the inner wall of the upper oil storage bin, and both end portions of the screw sleeve are provided with concave limiting sliding grooves, and the inner wall of the upper oil storage bin is convexly provided with guide convex strips adapted to the limiting sliding grooves.

[0007] As a preferred solution, the distance between the two guide ridges is not less than the diameter of the lower oil storage tank.

[0008] As a preferred solution, an oil guide groove is provided at the lower end of the groove, and the oil guide groove is in a trumpet shape that is wide at the top and narrow at the bottom, and the oil receiving through hole is connected to the oil guide groove.

[0009] As a preferred solution, a support frame is provided at the bottom of the oil guide groove, a first rib is provided in the middle of the support frame, and the oleophilic and hydrophobic sponge is arranged on the support frame.

[0010] As a preferred solution, a replaceable counterweight is provided at the lower end of the oil collecting pipe.

[0011] As a preferred solution, a cover is provided at the upper end of the groove, and the cover has a second rib.

[0012] As a preferred solution, a check valve is provided on the oil outlet pipe.

[0013] The above-mentioned marine oil separation collector has obvious advantages and beneficial effects compared with the existing technology. Specifically, it can be seen from the above-mentioned technical scheme that it mainly immerses the entire collector completely in seawater, fixes the oleophilic sponge in the groove on the turbine seat, and exposes the upper surface to contact with seawater. The turbine seat is driven to rotate by ocean currents or waves, thereby driving the piston to move up and down in the oil collecting pipe through the bidirectional threaded rod and the screw sleeve seat, and continuously forms a changing negative pressure in the oil collecting pipe, squeezing the oleophilic and hydrophobic sponge so that the oil absorbed by the oleophilic and hydrophobic sponge flows into the oil collecting pipe, and finally is discharged to the onshore oil collecting tank through the oil outlet pipe at the bottom of the oil collecting pipe for dewatering. It has the following beneficial effects: 1. The oil adsorbed by the oleophilic and hydrophobic sponge is deoiled by the negative pressure continuously formed in the oil collecting pipe, which will not cause mechanical damage to the material of the oleophilic and hydrophobic sponge, reduce the frequency of replacing the oleophilic and hydrophobic sponge and reduce the cost; 2. It can effectively and continuously absorb the residual oil on the sea surface, avoiding the disadvantage that the oleophilic and hydrophobic sponge cannot continue to absorb the oil after being saturated, reducing the labor intensity of workers and improving the efficiency of collecting oil; 3. By using natural ocean power such as ocean currents or waves to drive the turbine seat to rotate, the entire collection device can be operated continuously without the need for additional complex and energy-consuming power devices. The collector can work for a long time and uninterruptedly to continuously separate and collect oil in seawater, greatly improving the efficiency and coverage of oil collection.

In order to make the whole device suspended in seawater, the turbine seat 100, the oil collecting pipe 200, and the oil outlet pipe 300 can be made of plastic material, and in order to improve the oil suction efficiency, an oil pump can also be connected to the hose.

[0019] The oleophilic and hydrophobic sponge 400 referred to in this application can be a silane-grafted reduced graphene oxide-coated melamine sponge developed by the team of Associate Professor Gao Zuwei of Hainan University. It has excellent super-hydrophobic / super-oleophilic surface properties (water contact angle reaches 157.7°), has a high absorption capacity for a variety of oils (58.7-147.8g / g), and can undergo multiple absorption cycles. The separation efficiency of oil-water mixtures is as high as 99.32%, and the separation efficiency can still reach 97.48% after 80 separations.

[0020] Furthermore, the oil collecting pipe 200 includes an upper oil storage tank 210 and a lower oil storage tank 220. The diameter of the upper oil storage tank 210 is slightly larger than the diameter of the lower oil storage tank 220.
