Description

Marine floating oil collecting device

Technical Field

The utility model relates to the technical field of environmental protection equipment, in particular to a marine floating oil collecting device.

Background

With the rapid development of ocean transportation and offshore resource development, marine pollution events such as marine vessel and oil and gas field accident oil spill have become important factors affecting the marine environment. The oil spills into the sea, rapidly diffuses on the water surface, and isolates the sea from oxygen exchange with the air. Under the action of wind waves, part of oil can also form oil-water with water.

The adverse effects of marine oil spill are reflected in various aspects, firstly, the fuel oil in petroleum product oil can cause the human body to produce anesthesia, choking, chemical pneumonia, dermatitis and the like, and the health is affected; secondly, the oil film floating on the sea surface can reduce the oxygen production of the sea, directly cause the suffocation of marine organisms to death, and simultaneously, the petroleum pollution can inhibit photosynthesis and reduce O in the sea water ₂ The content of (2) destroys the normal physiological function of organisms, so that fishery resources gradually decline; finally, the oil film formed by the oil on the sea surface can obstruct gas exchange between the atmosphere and the sea water, and influences the absorption, transmission and reflection of electromagnetic radiation by the sea surface. Thus, the oil dirt floating on the sea surface must be removed as soon as possible.

At present, the main methods for collecting the floating oil at sea include three methods, namely a chemical method, a biological method and a physical method. The chemical method mainly adopts chemical agents to disperse or solidify spilled oil, namely, the pollution is reduced by changing the form of the spilled oil in the water area environment, and the chemical agents for treating the spilled oil comprise spilled oil dispersing agents, oil gathering agents, oil condensing agents, oil absorbing agents and the like, and are suitable for the situation that the spilled oil film is very thin. The biological method is to remove the spilled oil by biological decomposition, and the spilled oil removal time is longer. The physical method mainly adopts the characteristics that oil and water are not compatible and the density of oil is smaller than that of sea water to float on the sea surface, and during separation, the floating oil with small density is concentrated for post-treatment, and a mechanical device or an adsorption material is generally adopted to recover spilled oil. The existing floating oil collecting device has low treatment efficiency for treating a large amount of floating oil to be diffused in a large-area sea area; the multi-point small-area greasy dirt pollution scattered on the sea surface in a wide area is difficult to treat.
