Description
Technical field
The utility model relates to the centrifugal separation technology field, more particularly, relates to a kind of cyclone and air-floating apparatus that greasy dirt is handled that be used for.
Background technology
Can produce more oil-polluted water in the Petroleum and Petrochemical Industry production process.These oil-polluted waters are carried out a vital task of purification of water quality processing and remove oil droplet and suspension in the oil-polluted water exactly.The method and apparatus of removing oil droplet and suspension is varied, and method wherein commonly used has sedimentation separation, air supporting choosing, cyclonic separation, filtration method or the like.
Above-mentioned various processing method all has the pluses and minuses and the scope of application separately.Like sedimentation separation, main task is to accept the former water of oil-polluted water, simultaneously former water is carried out oil, water, suspension natural separation, and the recovered water that gets into the downstream flow process is carried out homogeneous, and all amount is handled.In this method, oil removing rate is 80%, and the suspended substance removal rate is 70%.Though treatment effect is better, because liquid residence time is long, so container volume is big, and the construction period is long, is applicable to disposing polluted water in oil station, land.
Treatment process maturation, small investment are selected in air supporting, and the time of staying is shorter, has been widely used in the oily waste water treatment engineering at present.But the deficiency of its existence is generally to adopt normal pressure to handle, and scum silica frost and oil slick are difficult to handle.And afloat gas more options nitrogen and air select the nitrogen expense high, select air big to the influence of water filling oxygen content, will increase deoxidation step during the flow process of downstream.
And be an oily water separation technique that comes out the 1980s based on the liquid-liquid rotational flow separation technology of hydrocyclone.It has advantages such as volume is little, in light weight, performance is good, safe and reliable to operation, but the profit density contrast less than 50kg/m3 and the situation of oil droplet size less than 30um under, remove efficient and can receive great influence, and the pressure of water and flow are had the requirement of strictness.
In order to overcome the shortcoming of traditional air supporting choosing and hydrocyclone, further improve oil-water separation, international in recent years many researchers and producer have all proposed the notion of compact air supporting screening device (CFU), propose some theoretical foundations and develop some equipment.The study limitation of domestic compact air supporting choosing is in the dissolved air flotation technology is combined with liquid-liquid hydraulic cyclone; Be in the development stage at present; Mostly the theory that proposes is aerating formula hydrocyclone; Such equipment still is subject to the treating capacity and the profit density contrast of single Taper Pipe, therefore can not use widely.
More external companies and research institution have released the composite set that air supporting and low-intensity cyclone technique combine; This apparatus processes adjustable range is big; And have certain treatment effect, therefore, the combination of air supporting and low-intensity eddy flow centrifugal force is the developing direction of compact air-floating apparatus.
At present, in the CFU device that the MI-SWACO of Norway produces, its cyclone device is that a cylindric inner core and a helical form inlet guide card are set in container, and oil-polluted water forms eddy flow from the tangential inlet entering jar on jar top, and bubble is separated out from water simultaneously.Minute bubbles and oil droplet rise to tank deck after being depressed into barrel under the effect of eddy flow centrifugal force field, discharge through the oil gas vent of tank deck.This device major defect is: centrifugal force intensity is low excessively; Air flotation effect is restricted, and is applied to the storage of platform or Floating Production when unloading oil tanker (FPSO), when platform or oil tanker rock; Be difficult to keep the stable of oil, gas, water termination, influence oil, gas, water scum silica frost efflux.Because this device does not have special sediment ejection opening, be applied to the more fashionable greasy filth that causes easily in field of silt content and pile up simultaneously, make that outer draining oil content is higher in the bottom, and unstable.
In the CFU device that the Siemens (Siemens) of Germany produces; Its cyclone is that cyath vin shape inner core is set in container; Contain of the tangential inlet entering of minute bubbles oil-polluted water from inner core; In inner core, form the low-intensity eddy flow, after oil droplet rose to the top inner cap with bubble, ozzle got into the discharge of oil-collecting space from inner cap top; Clear water gets into collecting space from inner tank theca, through being discharged by the ozzle of bottom after the coalescent pack.The CFU that the MI-SWACO of this cyclone and Norway produces compares, though be to adopt different inner parts structures to produce eddy flow to make water-oil separating; But it is very complicated all to have equipment inner structure, the shortcoming that processing cost is high.

Further, also be provided with a control valve 810 on the air inlet pipe 800.Through control valve 810, regulate air pressure and conform to, thereby keep the stable of oil gas water interface with tank body 200 interior pressure.
As an embodiment of the utility model, tank body 200 bottoms 240 are reverse taper, and the bottom of reverse taper is provided with greasy filth outlet 241.In the present embodiment; Tank base is designed to cone; Make heavier silt under action of centrifugal force, be thrown toward the cone wall and export 241 to greasy filth and discharge, make this air supporting screening device can be used in the occasion of high sediment concentration, enlarged its scope of application along wall flow.
Further, as the new embodiment of this enforcement, also offer a shunt valve 900 on the pipeline of connection injector 300 and cyclone 100, shunt valve 900 is communicated with reverse taper outer wall tangential.This tangential shunt valve 900 is set; Can make the mixed liquor that comes out from injector 300 get into cone and under the cyclone effect, form eddy flow better; The oil droplet, bubble and the water that separate through cyclone are pressed towards cone central authorities; Rise to weir plate 500 and surround flotation cell 520 and carry out flotation, heavier silt is thrown toward the cone wall in this process, and discharges to greasy filth outlet 241 along wall flow.
To sum up, the air supporting screening device in the present embodiment, the unique design of comprehensive cyclone 100 and weir plate 500 improves separating effect greatly.Facts have proved, be 6m3/h in treating capacity, and when the inlet oil content was the 500ppm left and right sides, the outlet oil content reached 6～7ppm after the above-mentioned air supporting screening device of two-stage is handled, and container diameter is merely 0.45m, and height is merely 2.6m, and the two-stage gross weight is merely 0.2t.This shows that the air supporting screening device in the present embodiment has oil removing performance efficiently.
More than be merely the preferred embodiment of the utility model,, any modification of being done within all spirit at the utility model and the principle, be equal to and replace and improvement etc., all should be included within the protection domain of the utility model not in order to restriction the utility model.
