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

The oil-absorbing device used for marine oil pollution control includes a plurality of oil-absorbing units connected to each other through buckles. Expanded graphite particles, two counterweight devices are arranged at the bottom symmetrical position of the outer frame of the monomer, and the ratio of the total weight of the two counterweight devices to the displacement of the oil-absorbing monomer is 1:5~1:10. The present invention calculates the buoyancy and adds a variable counterweight device so that the oil absorbing device always works at the interface between water and oil, and adopts a dragging rope to drag to form dynamic adsorption and improve the adsorption speed. According to the experimental measurement, the oil absorption efficiency is increased by more than 4 times ;This device has the practical effect of fast treatment speed and high adsorption cleanliness for the ultra-thin water surface oil spill commonly seen in oil spill treatment, and has the characteristics of tensile resistance, impact resistance and suspension.

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...
