Overwater overflow-oil recovery device in rotatable roller boom form

Abstract

The invention relates to an overwater overflow-oil recovery device in a rotatable roller boom form. The device is made of lightweight materials and comprises a roller and oil absorption elements, wherein the roller comprises a stand column (1) fixedly or detachably arranged on the middle of a roller bottom (7), a plurality of wall bodies (2) fixedly or detachably arranged on the circumference of the roller bottom (7), and covers (6) detachably covering the stand column (1) and the wall bodies (2); a shaft hole (12) is formed in the stand column (1); a flexible shaft or a cable penetrates through the shaft hole; the roller bottom (7) and the covers (6) are provided with through holes corresponding to the shaft hole (12); the adjacent wall bodies (2) are connected through a grid-shaped arc pore plate (3); each wall body (2) and the stand column (1) are connected through a grid-shaped plane partition plate (4); the roller is internally divided into a plurality of divided spaces; the oil absorption elements are disposed in each divided space; and the oil absorption elements can freely rotate in the corresponding divided space.

Description

technical field [0001] The invention relates to the technical fields of oil spill recovery and treatment at sea, water surface and water body pollution control, etc., and in particular relates to an oil spill recovery device in the form of a rotatable drum drag rail suitable for various water surface operations. Background technique [0002] Oil spills at sea have seriously polluted the surrounding environment. Oil spill accidents have occurred in almost all countries and regions with developed economic activities in the world. Quick and effective solution, oil spill recovery is a worldwide problem. Difficulties in marine oil spill treatment are: large area, thin oil layer, mechanical oil skimmers are ineffective; time requirements are high, and the spread of oil spills can be doubled for every additional day of treatment time; sea surface operations must rely on ships, the number, type, and sea conditions of ships These are the constraints of oil spill recovery operations....

AI Technical Summary

Problems solved by technology

Oil dispersants can disperse oil spills under certain conditions, but the oil spills have not been eliminated, nor have harmless chemical changes occurred, so their use is strictly restricted

[0004] The common oil-absorbing felt is a square sheet with a side length of about 400mm and a thickness of about 2 to 3mm. The main problem is that the efficiency of delivery and recovery is low. It is placed on the water surface for a long time to absorb water and sink, which is far from meeting the needs of oil spill recovery and treatment at sea.

The diameter of the cylindrical oil-absorbing drag bar is 300mm, 400mm, and the length of a section can reach 5 meters or longer. It can be connected as a long string of hundreds of meters to drag on the water surface. The oil-absorbing drag bar can only absorb about 0.1mm thick oil spill. 1 to 2mm to the inside of the oil-absorbing material, the oil-absorbing material has reached the adsorption limit for a few minutes after contacting the oil spilled on the sea surface, and the actual adsorption multiple does not even reach 1% of the product industry standard oil absorption multiple index
