Description
Technical field
The utility model relates to a kind of oily-water seperating equipment, especially relates to a kind of oily-water seperating equipment that separates crude oil in the oil field reinjection water.
Background technology
Oil field two is adopted three and is adopted and all need use a large amount of re-injection water, and re-injection water still contains substantial oil after getting oil, and in the past all with its direct re-injection, both the polluted underground water source caused oil reservoir to harden again, increases to continue cost of winning.The method of traditional water-oil separating has following several:
A. gravitational method.Gravitational method is fit to remove the oil slick in anhydrating, and its principle is to utilize the profit difference of specific gravity to make the oil come-up, reaches the purpose of water-oil separating.Oily-water seperating equipment based on the Gravity Separation principle is of a great variety, mainly contain flat, perforation ramp type (dull and stereotyped, corrugated plating) and coarse formula (the opposed type of branch ripple, tubulation and peak pipe) etc.
Flat oil interceptor has very long history, and the pond type is the simplest, and is easy to operate, and oil removal efficiency is stable, but floor space is big, influenced by flow nonuniformity, and treatment effect is bad.Perforation ramp type oily-water seperating equipment proposes " shallow pool principle " according to the inferior people of grade of the Chinese in 1904 flat oil interceptor is improved, the placement parallel-plate group that tilts therein, and angle can improve oil removal efficiency greatly between 30 °-40 °.Typical gravity oily-water seperating equipment has the AP I oil water separator of formulating by american petroleum institute standard, multilayer parallel-plate (PPI) type, inclination parallel corrugation plate (CPI) type and multilayer inclination double wave card peak valley opposed (MUS) type oily-water seperating equipment, sewage are respectively therein that monobasic flows, binary flows and ternary flows.In addition, also having Japanese NCP is the run-in index small echo double wave ripple oily-water seperating equipment of Mitsubishi's oily water purifier and China, little tubulation of flatwise and big tubulation oily-water seperating equipment etc.
The coarse formula is that material is filled in the coarse device, when waste water by the time can remove wherein dispersed oil.This key problem in technology is the coarse material, and the shape of material mainly contains fibrous and graininess.Hydrophilic material commonly used is to introduce acidic group (sulfonic group, phosphate etc.) and salt in fibers such as polyamide, polyvinyl alcohol, vinylon, and the lipophile material mainly contains wax shape ball, polyene system or polystyrene spheroid or foaming body, polyurethane foaming body etc.
B. flocculence.Flocculence is a kind of common method of handling oily waste water, occupies crucial status in wastewater treatment.Thereby this method forms the macromolecule floccule by adding suitable flocculant in sewage, effects such as process absorption, bridge formation, neutralization and embedding remove the polluter in anhydrating.Inorganic flocculating agent commonly used is aluminium salt and molysite, as aluminium chloride, aluminum sulfate, ferric trichloride and ferrous sulfate etc.
Novel flocculant is mainly inorganic polymer flocculating agent and composite flocculation agent in recent years.Inorganic polymer flocculant mainly is the polymerization system of aluminium salt and molysite.As polyaluminium chloride (PAC), polyiron sulfate (PFS), poly-silicon aluminium chloride (PASC), polymeric aluminum sulfate silicate (PASS) and ferric-polysilicate (PFSS) etc.Compound coagulant is bound to close by different salt and forms.
Organic flocculant commonly used is a polyacrylamide, ZB type cation organic flocculant etc.The research and development of organic polymer flocculating agent is very fast, but the application aspect the oily waste water processing, still mainly as the assistant of other method.
C. air supporting method.Air-float technology is that air is passed in the oily waste water, forms water-gas-grain three-phase mixed system, and in the process that bubble is separated out from water, micro-bubble becomes carrier, has adhered to water pollutant, and its density emerges much smaller than water.Because the stability of oil emulsion must take to take off steady, breakdown of emulsion measure earlier before the air supporting.The method of dosing coagulant commonly used, the electric charge on neutralization or change colloidal particle surface, the stability of destruction oil emulsion forms floccule body, and absorption oil droplet and suspension float jointly, strengthen the stability of foam.The hydroxyethyl fiber that adds hydroxyl group in the air supporting method is also arranged, methyl fiber and polyethylene nitrogen penta cyclic ketones and the polyethylene oxide that contains ethyl group, oil-water separating agents such as polyvinyl methyl ethermaleic anhydride take off steady method.
The air supporting method of using comprises pressure floatation air method, transformation air supporting method, turbine air flotation method and diffuser plate air supporting method etc. at present.
D. electrochemical process.Commonly used is electric flocculence, is characterized in using soluble anode such as metallic aluminium or iron to make sacrificial electrode, by chemical reaction, has both produced the needed bubble of dissolved air flotation, also produces the flocculant that makes the suspension flocculation.The electricity flocculence has that treatment effect is good, floor space is little, simple to operate, advantage such as the scum silica frost amount is less relatively, but exist the anode metal consumption big, need a large amount of salts make assistant medicament, power consumption height and the more high shortcoming of operating cost.Improved electric flocculence is mainly battery filter bed method, but technology that is that all right is ripe, still be in the exploratory stage.
E. bioanalysis.With the degraded of microorganism to waste water PetroChina Company Limited. hydro carbons, mainly be under the catalytic action of oxygenase, molecular oxygen is attached in the matrix, formation before this contains the oxygen intermediate, and then changes into other materials.Bioanalysis commonly used has activated sludge process, biological filter process, biomembrance process, contact oxidation method, aeration tower, deep well aeration, pure oxygen aeration and batch (-type) biological treatment etc. in proper order.But because the organism kinds in the oily waste water is various, state complex, treatment effect and bad, water outlet oil content height, thereby trend towards carrying out the research of separation screening dominant bacteria at present at oily waste water.Studying more bacterial classification has Zoogloea (Zooglea sp.), Azomonas (Azomonoas sp.) and pseudomonas (Pseudomonas sp.) etc., and wherein zoogleal treatment effect is best.
At present less permeable layer require the oil content of re-injection water to be lower than behind the 5ppm could re-injection, and require separating rate fast.And above-mentioned several method all can't reach requirement.
