Description
Technical field
The utility model relates to a kind of sorbing material for adsorbed water body greasy dirt, particularly a kind of for adsorbing the high efficiency composition asphalt felt of waters oil slick.
Background technology
Oil is modern society and the important energy thereof.Yet, in the processing of oil, in transportation, there are a considerable amount of Oil spills, discard in rivers and maritime waters, environment is caused to great threat.It is very difficult that removing oil pollution of waters dyes.The improvement of oil pollution has chemistry and physical method in the world at present.
Chemical method: by polluting feelings, condition adopts emulsion dispersion, oil-collecting or solidifying oily method are administered.The oil film that is less than 1 millimeter for thickness, it is effective adopting chemical detergent cleaning water body oil pollution.Yet the medicament that chemical debridement methods consumption is a large amount of, is also easy to cause secondary pollution, be a kind of processing mode of very uneconomical, environmental protection, use is fewer and feweri at present.
Physical method is the improvement method of commonly using the most.Physical method comprises the oil fence, contamination removing ship and attached retracting device and oil absorption material.Conventionally adopt the oil fence to control after greasy dirt scope, with oil absorbent material or oil receiving equipment, absorb greasy dirt.But no matter be that oil receiving equipment or oil suction Cottonopolis exist a common difficult problem, when processing high concentration gathering oil slick, oil receiving equipment and oil absorbent material can also represent higher efficiency, but when water body oil slick is processed to seven color oil bloom state of loose shape, thin, low concentration, the function of oil receiving equipment and oil absorbent material is basic inefficacy just.Because oil receiving equipment miscellaneous is all to utilize profit density variation, by centrifugal or gravity, bypass profit.Oil absorbent material is all to take the fine fibre that 100% polyphenyl alkene makes as raw material mostly, by the characteristic of its hydrophobic oleophylic, carrys out physical absorption.Once oil slick concentration is to a certain extent low, its adsorption capacity lost efficacy substantially, cannot be for advanced treating.
Asphalt felt is a kind of of oil absorption material application, and it is manufactured and form through melt-blown process by inertia chemistry polypropylene, and it is adsorptive liquid it is kept here effectively.Adsorption production is all in the polypropylene fibre or nonwoven processed through surface activation process agent being wrapped in sewer, outer cloth and tough and tensile durable, there is the extremely strong adsorptivity that powerful capillary absorbability brings, thereby absorb leakage liquid and flow to oil absorbent material, effectively stoped the diffusion of leaking, product is reusable after strand, extruding, can reclaim the leakage fluid (manufacturing process and the quality that depend on oil absorbent material) of 72%-90%.The manufacturing process of polypropylene oil suction felt is first to obtain fusion-jetting polypropylene nonwoven, then makes various forms of oil absorbent material sheets, absorption conservator, oil suction bar, oil suction rope, oil-absorption fence.
The technical process of polypropylene melt-blown asphalt felt is: polypropylene particles feeding---melt extrudes that------fiber is cooling, and---in spinning plate, becoming net---reinforces into cloth in fiber formation.
Asphalt felt specialty is applicable to absorb oil hydrogen class, hydrocarbon etc. and does not absorb water; Asphalt felt is used for the product on specialty absorption top layer, and the oil-based liquid on earth's surface during also can be used for raining.Inside stuffing repels the polypropylene of water for absorbing oil, this series products on the water surface time because not absorbing water, so still swim in after cell leakage liquid on the water surface can not sink under water (oils); Product category has absorption sliver, and adsorption cotton sheet and absorption pillow are selective.
Existing asphalt felt has stronger absorption, removing ability for waters middle and high concentration oil slick, but poor to the absorption of the low concentration greasy dirt on surface, waters and removing effect, use after existing asphalt felt, still there are oil bloom in surface, waters, oil absorbency is low, the efficiency of removing oil slick is low, can not deep purifying water body.
The technological core of high efficiency composition asphalt felt is Sorpure
tMefficient degreasing filtrate.It is the composite that a kind of microcosmic surface organic modification is processed.Its microcosmic crystal is " template " platelet packed structures, has exchangeable cations to exist between template." intercalation modifying " technology of utilization, by inorganic " template " organic modification of surface, makes its surface change lipophilic-hydrophobic property into from hydrophily.Efficient adsorption material is to realize the removal to oils or arene pollutant by distribution principle and ion exchange principle.Therefore, it is a kind of multifunctional ceiling enclosure material.On its layer structure surface, long-chain molecule can stretch in water, when contacting the water of oil-containing or organic pollution, be stretched in that long-chain molecule in water can combination be captured and is locked in its molecule framework by intermolecular strong interaction with oil or organic contamination composition granule.Based on its absorption principle, high efficiency composition absorption felt can be removed the greasy dirt of low concentration in water, and water purification water quality oil concentration reaches below 1ppm, really accomplishes deep purifying.
Summary of the invention
The purpose of this utility model is for problems of the prior art and the deficiency of removing oil pollution of waters, a kind of compound asphalt felt that can adsorb and remove waters low concentration greasy dirt is provided, the oil absorbency of asphalt felt of the present utility model is high, the efficiency of removing water body greasy dirt improves, especially good to the effect of removing water surface low concentration greasy dirt.
For realizing the purpose of this utility model, it is a kind of for adsorbing the compound asphalt felt of oil pollution of waters that the utility model provides, and several be arranged side by side oil suction unit and floating support units, consists of, and makes described compound asphalt felt swim in the surface of containing greasy dirt waters.
