Description
Technical field:
The invention belongs to the water treating equipment technical field, relate to the improvement of a kind of sewage solid-liquid separation and oily water separating equipment.
Background technology:
Different according to the oily(waste)water source with the existence form of oils in water, can be divided into oil slick, dispersed oil, oil in water emulsion and dissolving oil four classes: 1, oil slick, float on the water surface with external phase, form oil film or oil reservoir, its oil droplet size is bigger, generally greater than 100 μ m; 2, dispersed oil suspends in water with tiny oil droplets, often becomes oil slick after leaving standstill certain hour, and its oil droplet size is 10-100 μ m; 3, oil in water emulsion contains tensio-active agent and makes oil become stable emulsion in the water, oil droplet size is generally less than 10 μ m, and major part is 0.1-2 μ m; 4, dissolving oil is that a kind of the elaioleucite diameter is also thinner than oil in water emulsion with chemical mode dissolved microparticulate oil, sometimes can be little of several nanometers.
At present; the processing of oil extraction waste water can be divided into physics method (gravity settling, mechanical separation, centrifugal, coarse, filtration, membrane sepn etc.) by principle; chemical method (cohesion, acidifying, saltout, electrolysis etc.); physico-chemical processes (flotation, absorption, ion-exchange etc.), biological process (active sludge, biological filter, oxidation pond etc.).Because each oilfield sewage water quality differs greatly, handle after water water quality requirement and also be not quite similar, so the sewage treatment process in own oil field is determined in each oil field according to self practical situation and waterflooding requirement.Removal to oils mainly contains following four kinds of methods.
The nature oil removing can be removed oil slick and most of oil that looses in the waste water.Because natural oil removing dosing coagulant not, only by the relative density difference come-up of small oil droplet, suspended particle and sewage or sinking Jiang Shui, mud, separating of oil, so it is low to remove efficient, and volume is big, floor space is big.
The swash plate oil removing, it is one of high performance deoiling method commonly used at present, also is the deoiling method that utilizes the gravity separation technology.The ultimate principle of swash plate oil removing is " a shallow-layer theory ", briefly, is exactly that settling tank is shallow more, just can shorten sedimentation time more, improves oil removal efficiency.
Oil and water separation bygranulation, when it is meant oil extraction-generated waste water by the equipment that coarse material (weighting material) is housed, the process that oil bead diameter changes from small to big.Coarse equipment can be removed the oil droplet greater than 20 μ m, mainly is the dispersed oil of removing in the waste water.
The coagulation oil removing, it is by add coagulating agent in waste water, by compression double electric layer and charge neutrality effect, destroys colloidal stability, coacervation of colloid, particle are constantly increased, last gravitational settling gets off, and separates and removes.The coagulation oil removing can be removed oil in water emulsion and the colloidal solid in the waste water.
Though the treatment process of oily(waste)water is more, the whole bag of tricks all has its limitation.If use single method, be difficult to the effect that reaches satisfied.
Summary of the invention:
In order to address the above problem, the invention provides integrated coagulation synergy swash plate waste-oil scavenger, it combines swash plate oil removing and coagulation oil removing, realizes efficient degreasing and goes turbid effect.It mainly is made of: water inlet pipe (1), mixing equipment (2), grid flocculation equipment (3), water distribution orifice plate (4), Small angle swash plate (5), wide-angle swash plate (6), V-type dividing plate (7), rising pipe (8), V-type groove (9), oil exit pipe (10), bucket (11), shore pipe (12); Its principal character is: equipment is by coagulation and go turbid oil removing two portions to form, wherein the coagulation district is made up of mixing equipment (2) and grid flocculation equipment (3), realize coagulation synergy processing, sewage enters turbid oil-removing area by water distribution orifice plate (4) subsequently, utilize the swash plate realization deposit seeds of two kinds of different angles and the purpose of oil removing, two kinds of swash plate upper surfaces all can be realized precipitating action, and lower surface all can be realized the coalescent deoiling effect, the function difference that the variation by setting angle mainly realizes.Throw out is discharged through mud discharging device (11), (12), the oil slick class is discharged by the V-type groove (9) that goes to turbid oil-removing area upper end, exhalant region adopts V-type dividing plate (7) to avoid oils to enter rising pipe (8), sewage can reach coagulating sedimentation and deoiling effect efficiently through behind this integrated coagulation synergy swash plate waste-oil scavenger.
Coagulation partly adopts two kinds of equipment to realize mixed effect efficiently in the integrated coagulation synergy swash plate waste-oil scavenger, mixing equipment (2) is installed in the pond external body, after sewage passes through mixing equipment (2) by water inlet pipe (1), and access arrangement, by grid flocculation equipment (3), realize coagulation synergy purpose again.The turbid oil-removing area of going of integration apparatus is equipped with the swash plate of two kinds of angles, and the lower section is Small angle swash plate (5), is mainly used in coalescent deoiling, its setting angle is 30 °-55 °, top is wide-angle swash plate (6), is mainly used in the particulate precipitation, and its setting angle is 45 °-65 °.The oil extraction district adopts V-type groove (9), and for the oil slick district on upper strata, V-type groove (9) has the effect of automatic oil skimming, reduces its power consumption.Be provided with V-type dividing plate (7) at exhalant region, cause the partition of exhalant region profit, oils is arranged to avoid mixing in the water outlet.
Beneficial effect of the present invention:
(1) coagulation, remove turbid oil removal treatment efficient height
Owing to mix rapidly, can shorten the residence time of sewage in treatment facility greatly.Simultaneously because the common use of coagulation oil removing and swash plate oil removing, two kinds of different angles swash plates shared, the design of oil extraction district, exhalant region V-type groove can reach three phase separating efficiency preferably, has reduced the load of subsequent processing device.
(2) floor space is little
Because incorporate design of equipment and device processes efficient height, so floor space is little.
(3) strong shock resistance, it is extensive to be suitable for water quality
When former water temp, flooding velocity, add dose when some taking place changing, do not influence effluent quality.
(4) effluent quality is good, and processing cost is low
Because of equipment does not need mechanical part, there is not power consumption, low being convenient to of cost safeguarded, guarantees that stable effluent quality is up to standard.
