Special offshore deoiling oil absorbent felt and method for preparing oil absorbent felt

Abstract

The invention discloses a special offshore deoiling oil absorbent felt. The special offshore deoiling oil absorbent felt comprises an oil absorbent felt body which is prepared from an oil absorbent fiber, is provided with an oil absorbent clearance part, and comprises two oil absorbent fiber layers; the oil absorbent clearance part formed between the two oil absorbent fiber layers is filled with a water-repellency oleophylic material, and the two oil absorbent fiber layers and the water-repellency oleophylic material are solidified integrally. The preparation method comprises the following steps: (1) pretreatment, namely preparing the water-repellency oleophylic material for filling for later use, and selecting an oil absorbent fiber for later use; (2) producing an oil absorbent fiber layer; (3) laying a water-repellency oleophylic material; (4) solidifying; and (5) coiling. An oil containment boom prepared from enteromorpha has good oil blocking and oil absorption performances, the use effect of the oil containment boom can be enhanced, the oil containment boom can float on the water surface for a long time after oil absorption, can not sink or deform, and has good oil absorbing and blocking effects.

Description

technical field [0001] The invention belongs to the technical field of oil spill treatment on water, and in particular relates to an oil-absorbing felt cloth specially used for oil removal at sea and a method for preparing the oil-absorbing felt cloth. Background technique [0002] Enteromorpha algae, widely distributed in the oceans of the world, some distributed in brackish water or rivers, often grow on rocks or bogs in the intertidal zone, or on the gravel of mud beaches, sometimes attached On the algae of large algae. Enteromorpha is a new type of marine ecological disaster in my country's coastal waters. Since 2008, it has periodically erupted and disappeared in the Yellow Sea every year from May to August. The blue ocean has become a green grassland, which is called "green tide". Cause different environmental impacts and economic losses. Although Enteromorpha is non-toxic, like red tides, the mass-proliferated Enteromorpha can also shade the sun and affect the growth...

Problems solved by technology

[0005] Although the above-mentioned patents can achieve the effect of oil confinement and oil collection, they cannot achieve the effect of oil absorption. The most widely used oil containment boom structure in the prior art is: put the foam core on the cable, and then wrap the foam core around the oil absorption. The non-woven fabric made of non-woven fabrics is finally made by manually covering the fixed net outside the non-woven fabric and winding it. The advantage of this oil containment boom is that it can not only surround the oil slick, prevent the spread of the oil slick, but also prevent the spread of the oil slick. Slick oil is absorbed on the non-woven fabric outside the foam core

However, the current oil-absorbing materials made of non-woven fabrics generally use fibers such as polypropylene, high-strength polyethylene, and polyester. After all, the oil-absorbing properties of these fibers are limited, and the limited oil-absorbing materials wound on the foam core cannot exert their maximum oil-absorbing effect.
