Description
Technical field
Present invention relates particularly to a kind of super oleophylic and super-hydrophobicity oil-water separation filter papers and preparation method thereof, and this patent belongs to
Functionalizing material surface is modified field and oleophilic oil material field.
Background technology
Oily water separation technique is in industries such as many fields such as oil, chemical industry, steel, coking, household electrical appliances, machine-building, environmental protection
Urgent demand is suffered from, especially there are a large amount of oily waste waters to need to handle in field of environment protection；According to OTM and Douglas-
The statistics of Westwood, the whole world can all generate 2.41 hundred million barrels of industrial waters related with oil gas daily, arrive the year two thousand twenty, and yield is pre-
Meter will rise to 2.92 hundred million barrels, and the ocean oil accident to take place frequently during offshore oil production and transportation, can all generate
A large amount of oily waste water needs to handle, if these waste water cannot efficiently separate processing and be directly discharged to the meeting of going in environment
Health and natural ecological environment to people bring serious harm.The mixed form of oil and water is more in practical applications
Sample, predominantly following four：(1) floating oil:The water surface is floated on continuous phase, forms oil film or oil reservoir, the oil droplet of this oil
It is relatively large in diameter, generally higher than 100 μm；(2) dispersed oil：It is unstable with tiny oil droplets suspended dispersed in water, static certain time
Larger oil droplet can be gathered into and oil slick can be become by floating to the water surface, oil droplet size is at 10~100 μm；(3) oil emulsion：Because containing in water
There is surfactant and oil and water is made to form stable emulsion, oil droplet size is generally less than 10 μm, and major part is at 0.1~2 μm；
(4) dissolved oil：It is a kind of system for the stable and uniform for being scattered in molecular state and being formed in water body, elaioleucite diameter is than oil emulsion
It also wants small, may diminish to several nanometers sometimes；And often exist with first three physical state in practical polluted-water.
Currently on the market main oily water separation technique mainly have Gravity Separation, ultrasonic separation, absorption, dissolved air flotation,
Centrifugation, coagulation sedimentation, electrochemical process and biological treatment etc..But these isolation technics are in actual water-oil separating
There is a problem that in journey it is certain, as that there are disengaging times is long, equipment volume is big, treated, and water quality is not up to standard for gravitational separation process
The shortcomings of needing to be further processed, that there are energy consumptions is excessively high for ultrasonic method, cost of equipment is high, technology requires the shortcomings of high；Absorption method
In the presence of cannot operate continuously, the disadvantages such as material recycling rate of waterused is low；There are high energy consumption, operational administrative complexity etc. to lack for dissolved air flotation method
Point；Centrifugal separation technology there are high energy consumption, it is poor to the separating effect of high viscosity oil product and oil emulsion the shortcomings of；Coagulation sedimentation
That there are medicaments is expensive, sludge output is more, be easy to cause the shortcomings of secondary pollution；Electrochemical process there are of high cost, technology require it is high,
Treated the problems such as water usually requires after-treatment；Biological treatment exists the disadvantage is that taking up a large area, easy ting produce dirt
The problems such as mud, higher technical controlling level requirement；Therefore it needs to develop new oily water separation technique to handle a large amount of oil-containing
Waste water.
Membrane technology is because have many advantages, such as that the high and low energy consumption of separative efficiency, the easy to operate and device space are small and divide in grease
From in field have huge application prospect.But there are fouling membranes seriously to cause to transport in actual separation oily waste water for membrane technology
For row at the problems such as high, water flux is low, the key for overcoming the problems, such as these is development of new membrane material, prepares with super oleophylic and surpasses
The membrane material of hydrophobic property is one of current research Main way.
Through retrieval, find as follows with the relevant patent document disclosure of the application：
Patent CN105964014A discloses a kind of preparation method of hydrophobic oleophilic oil type hollow fiber composite membrane, by hydrophobic
Kynoar, hydrophobicity pore former and graphene be blended into spinning solution, then doughnut is prepared by spining technology
Film, although the Hollow-fibre membranes material can efficiently separate oil-water mixture, antifouling property is stronger simultaneously, needs
It is run under the conditions of certain operating pressure, this can increase actual application cost.CN107050928A discloses a kind of grease point
From with porous nethike embrane of super-hydrophobic super-oleophylic and preparation method thereof, by priority on porous nethike embrane coated thermoplastic, hydrophobic
Nanometer silicon dioxide particle prepares the porous nethike embrane of super-hydrophobic super-oleophylic, and the porous nethike embrane of preparation can be real under gravity
Separation rapidly and efficiently now can be realized to a variety of oil water mixtures, can be recycled for multiple times, but the preparation method is complicated, needs
Repeatedly coating, preparation process is complicated, is unfavorable for industrialized production.CNIO6868948A discloses a kind of with oil-water separating function
Filter paper and its simple preparation method and application, mainly by being loaded with organic/inorganic composite hydrophobic layer in surface, preparation
Hydrophobic papery has very high water-oil separating efficiency, but the hydrophobic performance of the filter paper is not strong, and water contact angle is only up to 140 °,
The performance requirement of super-hydrophobic (water contact angle is more than 150 °) is not achieved, it will influence actual oil-water separation.
Therefore, longer etc. ask is taken for the preparation method generally existing complex process of existing water-oil separating material, preparation
Topic, while being partially separated material and needing that just there is very high separative efficiency under the conditions of external driving force, this will increase actual
Operating cost, and method water-oil separating material poor therefore simple and fast by preparation method, economic in terms of recycling
While more low energy consumption, higher separative efficiency and the recycling rate of waterused of the water-oil separating material that prepare will be of great significance
