Problems solved by technology

But there are the following problems: the former's drag bar is almost completely floating on the water surface, and when there are slight waves on the water surface, it will slide over the oil spill surface and lose its confinement effect. Practical problems; the latter has low single-chip delivery and recovery efficiency, and also has practical problems such as small adsorption contact surface, slow speed, and unclean suction.
The melt-blown polypropylene oil-absorbing drag rail and oil-absorbing felt after actual use contain about 10-20% saline seawater. The saline oil product has no use value in subsequent treatment, and there is also a major safety hazard in burning treatment, so it can only be used as landfill , easy to cause secondary pollution

Abstract

Disclosed is an oil absorption device for ocean oil contamination treatment. The oil absorption device comprises a plurality of oil absorption single bodies which are connected with one another through retaining rings. Each oil absorption single body comprises a single body outer framework and an oil absorption core bag placed in the single body outer framework. Expanded graphite particles are contained in each oil absorption core bag. Two balance weight devices are arranged at the symmetrical positions of the lowermost portion of each single body outer framework, and the specific value of the total weight of the two balance weight devices to the displacement of the corresponding oil absorption single body is 1:5 to 1:10. The oil absorption device works at the interface of water and oil all the time by adding the variable balance weight devices through buoyancy calculation; dynamic adsorption is formed by dragging a dragging rope, and the absorption speed is increased; through experimental determination, the oil absorption efficiency is improved by more than four times. The oil absorption device has the actual effects of being high in treatment speed and high in absorption cleanliness on ultrathin water surface spillage oil commonly happening to oil spillage treatment; meanwhile, the device has the advantages that stretching resistance and impact resistance are achieved and the device can be suspended.

Description

technical field [0001] The invention relates to the technical field of marine oil pollution control, in particular to an oil absorbing device for marine oil pollution control. Background technique [0002] The main pollutant of marine pollution is petroleum hydrocarbon oil pollution, which can cause hypoxia and poisoning of water bodies, cause loss of coastal wetland area, and cause harm to industrial and agricultural production such as fishery, salt industry, and seawater desalination. There are generally two ways to clean up traditional marine oil pollution adsorption products: first, use soft melt-blown polypropylene material as the core body, and outsource PVC and other plastic mesh bag materials to make long cylindrical oil-absorbing drag rails; Spray polypropylene material to make a square oil-absorbing felt with a thickness of about 1-2mm and a square of 30-50cm, and its oil absorption is 10 to 20 times its own weight. But there are the following problems: the former...
