Description
Technical field
Water-oil separating filtrate media technology field of the present invention, more particularly to a kind of hydrophilic oleophobic compositions.
Background technology
China's oil field distribution is wide, throughout northeast, North China, Central-South, southwestern, Central China and southeastern coast various places.Due to China
Most of oil field has been enter into the middle and later periods developed, and the water content in extraction oil is very high, and substantial amounts of oily waste water is produced after crude oil collection
Water --- recovered water, up to 70%～80%, some oil fields are even as high as 90% to moisture content, and substantial amounts of containing is produced after water-oil separating
Oily water.Oil-polluted water needs Jing process to discharge again, can otherwise cause the pollution at soil, water source.Quartz sand, walnut shell are current parents
The two kinds of filtrates commonly used in water oleophobic filter, but the nonideal distribution of pores of filtrate so as to which treatment effect is limited, and
Filtrate is easily lost in, needs the timely shortcoming supplemented to also limit the further genralrlization of both filtrates.Fiber-ball filter media due to
Preferable distribution of pores can be formed under deadweight and hydraulic action, so go the effect of oil removal preferably, at present in Jiang-Han Area, standard
You have applied in oil field.But, because fiber-ball filter media has nonpolar oil-wetted surface, the greasy dirt in recovered water easily adsorbs
Thereon so that fibrous nodules easily bond it is agglomerating, be difficult rinse regeneration, so as to limit fiber-ball filter media in oil field produced water process
In popularization and application.And general ceramic particle is simply used as filtrate, and there is pore plugging, increase lacking for working resistance
Point, some porositys are low, poor filtration effect, and what is had is even easily aging.Therefore a kind of compound hydrophilic oleophobic combination is researched and developed
Thing will become hot research direction.
The content of the invention
The technical problem to be solved is to provide a kind of hydrophilic oleophobic compositions, its have strong oil repellent and
Ultrahydrophilic, significantly, filter cycle is long for filter effect, and reproducibility is strong, and heat-resisting and heat endurance is good.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of hydrophilic oleophobic compositions, are made up of the raw material of following weight portion：
80～90 parts of ceramic particle
10～20 parts of polytetrafluoroethylene (PTFE).
Ceramic particle of the present invention, is made up of the raw material of following weight portion：
The preparation method of ceramic particle of the present invention, comprises the following steps：
1) silica, aluminum oxide, spodumene, calcium carbonate, iron oxide, calcium oxide and magnesia, ball are weighed by formula ratio
Mill 18～24 hours；
2) add formula ratio water, place 2～6 hours；
3) balling-up is granulated, it is 2～6% to be dried to moisture content；
4) in the case where heating rate is 2～3 DEG C/min, carry out burning till 1～3 hour, be down to room temperature.
Preferably, hydrophilic oleophobic compositions of the present invention, are made up of the raw material of following weight portion：
85 parts of ceramic particle
15 parts of polytetrafluoroethylene (PTFE).
Preferably, the preparation method of ceramic particle of the present invention, 3) in bulb diameter be 1.6～2.6mm, take the diameter big
Hour, hydrophilic oleophobic effects are the most notable, and backwash effect is preferably also.
Preferably, the preparation method of ceramic particle of the present invention, 4) in burnt at a temperature of 1040 DEG C～1140 DEG C
Into.Under the firing temperature so that the porosity and crushing strength of ceramic particle reaches optimal balance point, ceramics are greatly improved
The performance of grain.
Polytetrafluoroethylene (PTFE) of the present invention be polytetrafluoroethylene (PTFE) silk ligation solid spherical body, its a diameter of 2～
4mm.The polytetrafluoroethylene (PTFE) of the diameter is combined with a diameter of 1.6～2.6mm ceramic particles, significantly improves hydrophilic oleophobic combination
The combination property of thing.
The beneficial effects of the present invention is：
The present invention is combined ceramic particle with polytetrafluoroethylene (PTFE) synthetic fibers, both remained it is respective a little, while also gram
Respective deficiency is taken, both combine the hydrophilic oleophobic compositions for preparing and have strong oil repellent and ultrahydrophilic,
Chemical stability is good, considers speed height, and intensity is high, and heat-resisting and heat endurance is good, nonpoisonous and tasteless, and environmental protection, filter cycle is long, power of regeneration
By force, after backwash, can substantially recover original filter capacity, with longer service life, while anti-microbial property is good, be difficult by bacterium
Degraded.The present invention hydrophilic oleophobic compositions suitable for hydrophilic oleophobic separator, as filtrate medium.After testing, Jing Guoben
Invent ammonia, nitrogen, nitrite nitrogen content in the water after hydrophilic oleophobic compositions are filtered lower than general filtrate by 40～60%, iron, manganese
Low by 45～75%, the index such as oxygen demand and microorganism also has reduction.
