Abstract
The utility model discloses an oil resistant fiber filter material belonging to the technical field for treating polluted water. The utility model is composed of a bundle of fiber. The bundle of fiber is fixed from the middle part of the bundle of fiber, a fixed point is used as a center, and a sphere is formed. The surface of the fiber is attached with an oil resistant hydrophilic compound coating layer. The utility model overcomes the disadvantages that a fiber ball is easily stuck by oil pollution, the fiber ball can not be cleaned or regenerated, and a filtering effect is poor existing in the prior art. The utility model is mainly used for treating polluted water which contains oil for an oil field, an oil refinery and a petrochemical industry enterprise.
Description
Technical field
The utility model belongs to a kind of fiber filtering that is used for water treatment, especially for the grease proofing fiber filtering of oily waste water treatment.
Background technology
The filtering oily sewage of oil field, oil plant and petrochemical enterprise is handled and is generally adopted traditional rigid particles filtrate and the ball elastic filter material of fiber at present.Traditional rigid particles filtrate, as coal, quartz sand and walnut shell etc., its voidage has only 50%, and retaining power is limited, and the space distribution is up-small and down-big, and the upper strata is stopped up easily, and filter effect is relatively poor; The patent No. is 85200039 Chinese patent, a kind of fiber-ball filter media is disclosed, be fiber to be pricked knot and made fiber filtering with fine rule or filament, its voidage of this fiber-ball filter media reaches 92%～95%, the space is distributed as up big and down small, have the filtering velocity height, cut advantages such as the mud amount is big, but because fiber has nonpolar oil-wetted surface, greasy dirt very easily adsorbs on it.Therefore, such fiber-ball filter media is in use very easily by the bonding of the greasy dirt in the sewage, and the cleaning difficulty, causes it can not wash regeneration, and service life is short, thereby has limited fiber filtering applying in oily waste water treatment.
The utility model content
At the shortcoming of fiber-ball filter media in the prior art, the utility model provides a kind of filtering accuracy height, treatment effect is good and the grease proofing fiber filtering of regeneration capable of washing.
The utility model comprises following two kinds of technical solutions:
Scheme one:
A kind of grease proofing fiber filtering by a branch of fibrous, is tightened a described bundle fiber with fine rule or filament, and is formed centrally sphere to prick node in being; Its design feature is that the surface of described fiber is with refusing oily hydrophilic compounds coating.
According to technique scheme, described to refuse oily hydrophilic compounds be the nonionic fluorochemical.
According to technique scheme, described fiber is a dacron thread.
Scheme two:
A kind of grease proofing fiber filtering, by a branch of fibrous, its design feature is, is equipped with pad on the described bundle fiber, and is formed centrally sphere in pad being, the surface of described fiber is with refusing oily hydrophilic compounds coating
According to technique scheme, described to refuse oily hydrophilic compounds be the nonionic fluorochemical.
According to technique scheme, described fiber is a dacron thread.
Grease proofing comparison:
Make a grease proofing fibrous nodules by the technical solution of the utility model, be called the A ball, make an onesize fibrous nodules, be called the B ball by prior art.Immerse A ball and B ball in the crude oil simultaneously and it is fully contacted with crude oil, about 30 minutes latter two fibrous nodules oil-containings state that reaches capacity.Take out A ball and B ball and put into water respectively and wash, and examine discovery: A ball one is put into water, and the crude oil on surface turns to oil droplet immediately and spills in the water, less than 30 second the A ball recovers the white surface that cleans fully; And the B ball just has few crude oil to spill in the water in the surface, and whole fibrous nodules can't clean up.
The filtering oily sewage test:
Make fiber filtering by the technical solution of the utility model, and it is made filter course experimentize.The rate of filtration is 15m/h, and the cycle of operation was 3 cycles, and the phase is 7 days weekly, and its result is as follows:
When average oil content, suspension solids content, total number of particles and the suspended particle median diameter of sewage is respectively 11.0mg/l, 11.55mg/l, 264600/ml and 4.767 μ m, filter the average oil content of back water outlet, average suspension solids content, average grain sum and average suspended particle median diameter and be respectively 2.4mg/l, 2.0mg/l, 20040/ml and 1.902 μ m.
The backwash result of the test:
In above-mentioned filtering oily sewage test, after the phase end filter course is recoiled weekly.In 2 months run duration, under the water inlet situation of greasy dirt content less than 20mg/l, the instantaneous greasy dirt content that recoils out after finishing is all up to about 2000mg/l the phase weekly, and for the water inlet greasy dirt 100 times illustrate that repercussion effect is fine.
Can find out by above-mentioned test, the utlity model has the soil removal efficiency height, non-caked, be easy to clean and advantage such as use again.
Accompanying drawing and description of drawings
Fig. 1 is the shape figure after the utility model embodiment 1 pricks knot;
Fig. 2 is the shape figure after the utility model embodiment 2 welding;
Fig. 3 is the shape figure after the fiber filtering of Fig. 1 or Fig. 2 is put in order.
The specific embodiment
Get a branch of length and be the dacron thread 1 of 20mm and its arrangement is neat, from the center it is tightened by the waist, its arrangement is obtained presenting then the suede group of sphere with fine rule 2; This fibrous nodules is put into the oily hydrophilizing agent of refusing that is mixed with by the nonionic fluorine-containing emulsifier soaked about 6 minutes, then it is dried down at 130 ℃, promptly make grease proofing fiber-ball filter media 4 as shown in Figure 3.
Get a branch of length and be the dacron thread 1 of 40mm and its arrangement is neat, make pad 3 in the middle, make dacron thread together, then its arrangement is obtained presenting spherical suede group in this pad place strong bond with electrical heating method; This fibrous nodules is put into the oily hydrophilizing agent of refusing that is mixed with by the nonionic fluorine-containing emulsifier soaked about 5 minutes, then it is dried down at 100 ℃, promptly make grease proofing fiber-ball filter media 4 shown in Figure 3.The solder joint of present embodiment also can be realized by laser weld and infrared welding.
Its surface of the fiber filtering that the foregoing description is made is adsorbed with a large amount of surfactants, has significantly different with the fiber-ball filter media surface of prior art.This is because fiber filtering is when soaking in refusing oily hydrophilizing agent, under the osmosis of water, refuse surfactant in the oily hydrophilizing agent attached to the filament surface, solvent evaporation when baking, surfactant is separated from solution, on the one hand with surperficial amorphous area in free radical generation chemical graft; Be adsorbed on the surface of fiber on the other hand by physisorption, during absorption, because fiber surface has nonpolar, surfactant is generally with the close surface of solids of lipophilic group, hydrophilic group outwardly, like this along with absorption carrying out, apolar surfaces originally becomes hydrophilic polar surfaces gradually.
