Embodiment 1

[0029] see Figure 1-4 As shown, the device used to recover oil leaked from the seabed after a marine accident has

[0030] The upper and lower sealing barrel-shaped separation tank 6, the separation tank 6 is divided into at least three chambers from top to bottom by the hydrophilic fiber block 10, the separation tank 6 is provided with a coaxial liquid inlet pipe 11, and the liquid inlet pipes in each chamber of the separation tank 6 11 is provided with a throw-out mechanism 9, and a water outlet 8 is provided at the connection with the throw-off mechanism 9, and each chamber is provided with an oil suction pipe 5, and the bottom of the separation tank 6 is connected to a water outlet pipe 12 at the bottom of the chamber;

[0031] The ejection mechanism 9 includes two coaxial inner tubes 905 and outer tubes 901, and the inner and outer tubes are evenly distributed with arc-shaped rotary blades 903 in section, and the inner tube 905 between the two rotary blades 903 is provid...

Embodiment 2

[0044] This embodiment provides another kind of device technical solution for recovering seabed oil leakage after a marine accident. This technical solution further adds the following technical solution on the basis of embodiment 1: as Figure 5 As shown, a curved filter plate 10a is provided inside the hydrophilic fiber block 10 of the present invention. The cross section of the curved filter plate 10a is in a concave state, and the mesh of the curved filter plate 10a is 100-200 mesh. The present invention utilizes the arc-shaped filter plate 10a to guide the treated water flowing through the hydrophilic fiber block 10 so that it flows along the arc-shaped filter plate 10a in the hydrophilic fiber block 10 to the center of the hydrophilic fiber block 10 and flows downward. Correspondingly, increasing the central pressure of the hydrophilic fiber block 10 increases the passing rate of the water body passing through the hydrophilic fiber to reduce the clogging probability of the...

Embodiment 3

[0046] When the device of the present invention for recovering seabed oil leakage after a marine accident is actually used: when oil leakage occurs in the sea area, surround the plastic pipe around the leakage range and seal it with a clip at the joint, such as Figure 6 As shown, the water pump 3, the suction pipe 2 and the liquid inlet pipe 11 are used to send the treated water containing more leaked oil in the upper layer of the sea into the separation tank 6, and the treated water leaked from the sea surface is pumped into the top chamber of the separation tank 6 for use. It flows from top to bottom under the action of gravity, and the oil and water are separated through the hydrophilic fiber block 10. The oil suction pipe 5 absorbs and concentrates the separated oil into the oil storage tank 4 for subsequent treatment, and the treated water flows down to the separation tank under the action of gravity 6. After the water body at the bottom most has very little oil content, ...

Abstract

The invention discloses a device for recovering seabed oil leakage after a marine accident, belonging to the field of offshore oil recovery engineering. The device has a barrel-shaped separation tank with upper and lower seals, and the separation tank is divided into at least three chambers from top to bottom by hydrophilic fiber blocks. , there is a coaxial liquid inlet pipe in the separation tank, a throwing mechanism is provided on the liquid inlet pipe in each chamber of the separation tank, and a water outlet is opened at the connection with the throwing mechanism, and an oil suction pipe is provided in each chamber, and the bottom of the separation tank is The bottom of the end chamber is connected to the water outlet pipe; the throwing mechanism includes two coaxial inner and outer pipes, and the inner and outer pipes are uniformly distributed with arc-shaped rotating leaves, and the inner pipe between the two rotating leaves is provided with strips. The notch corresponds to the position of the water outlet, and the inner pipe is rotatably connected to the liquid inlet pipe through the bearing ring. The invention utilizes the gravity sedimentation method to recover leaked oil, effectively reduces the water content of the recovered oil, rapidly separates water, oil, and gas, and has high oil recovery rate and fast processing efficiency.

Description

technical field [0001] The invention belongs to the field of offshore oil recovery engineering, and in particular relates to a device for recovering oil leaked from the seabed after a marine accident. Background technique [0002] Oil pollution refers to the pollution caused by leakage and discharge of oil during oil extraction, transportation, loading and unloading, processing and use, mainly in the ocean. Oil floats on the sea surface and rapidly spreads to form an oil film, which can be migrated and transformed through diffusion, evaporation, dissolution, emulsification, photodegradation, biodegradation and absorption. Offshore oil drilling and extraction have become a part of industrialized life in today's world. No matter in the process of energy exploitation or in the process of offshore oil transportation, some accidents such as accidental leakage will inevitably occur. Faced with such a situation, not only will the sea water be polluted by oil, which will endanger ...
