Problems solved by technology

However, dispersants are often highly toxic, and when the oil spill area is large, the oil removal efficiency is not high, and it is only suitable for the treatment of oil spills on the sea surface
The second is the coagulation method, that is, the oil coagulant is used to rapidly increase the viscosity of the oil, so that the slick oil is formed into lumps, which is convenient for recovery. The coagulation method is not as common as the dispersion method, because the production process is complicated, the cost is high, and the recovery is difficult.
In the actual treatment of large-scale oil slicks, the use of such a high ratio of dispersant to oil spill results in a relatively high treatment price
Dispersants are usually sprayed by special devices such as ships and aircrafts. Aircraft spraying is used to deal with large irregular oil films. The thickness of the oil film covering the sea surface is different. A large amount of waste of agent increases the processing cost

Abstract

The invention discloses composite oil absorbing cotton for cleaning oil on a water surface. The composite oil absorbing cotton comprises an oil absorbing cotton body, wherein the oil absorbing cotton body comprises an oil absorbing layer and a hydrophilic film layer fixed on the oil absorbing layer, the hydrophilic film layer is made of non-woven fabric formed by compounding polyester and wood pulp cellulose, the oil absorbing layer is made of polypropylene, and a plurality of oil seepage holes are formed in the hydrophilic film layer. The hydrophilic film layer is arranged on the oil absorbing layer and can quickly and completely absorb oil floating on the water surface; the composite oil absorbing cotton replaces current oil spill chemical dispersants, causes no pollution to water while absorbing oil on the water surface and is efficient and environment-friendly. The oil seepage holes are formed in the hydrophilic film layer and can effectively absorb oil on the water surface by guiding the oil into the oil absorbing layer, and the oil absorbing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of oil pollution treatment, in particular to a composite oil-absorbing cotton used for cleaning oily spots on water. Background technique [0002] When an oil spill occurs on the sea surface, or when an oil spill occurs in a factory and pollutes the nearby river, there are generally three methods to remove the oil pollution. One is the dispersion method, that is, the oil dispersant is used to break the oil film, making it into particles and dispersing into the water phase. In the middle, the oil dispersant accelerates the micronization process of the oil, makes the oil diffuse in the vertical direction, and does not form an oil film on the surface of the water body, so that it does not adhere to ships, reefs and coastlines. The use of dispersants increases the surface area of ​​the oil and accelerates the biodegradation of the oil. However, dispersants are often highly toxic, and when the oil spill area is large, the...
