Description
Technical field
The present invention relates to a kind of oily waste water treatment technology, is to be related to a kind of adjustable list of stabilizing feed well in particular
Tank twin-stage cyclone air-flotation device.
Background technology
With continually developing for oil gas field, oil field extracted water proportion in Produced Liquid is continuously increased, or even the oil having
Up to more than 90%, recovered water is continuously increased field Produced Liquid moisture content, and huge pressure is brought to downstream unit for treating water.
Most ground produced water treatment system is because settling time is more early, in can only meeting, the requirement of low Water-cut Period, contains for height
The water phase, the disposal ability of the water treatment facilities of early stage is substantially insufficient, and treatment effeciency is relatively low, must not sometimes to meet treatment effect
It is not combined with other processing methods, adds the cost of water process.Water treatment facilities are proposed by the particularity of offshore platform
Higher requirement, not only there is higher treatment effeciency, also to meet that compact-sized, economy and the feature of environmental protection etc. are many hard
Property require.In addition, as most of oil field in China Bohai Sea and South China Sea progresses into the middle and later periods of exploitation, what early stage built
Water processing establishment generally existing treatment effeciency is low, it is difficult to meets discharge standard, but the upgrading of water treatment facilities suffers from
Platform space is nervous and reduces the limitation of construction cost, and there is an urgent need to research and develop the water treatment facilities of compact efficient.
The processing of extracted waste water can be divided into according to the difference of principle：Physical (gravitational settling, filtering, coarse, machinery
Separation, UF membrane etc.), chemical method (flocculate, aoxidize, being electrolysed, saltouing), physical-chemical process (flotation, absorption, ion exchange
Deng), bioanalysis (activated sludge, biofilter, oxidation pond etc.).Every kind of processing method has the advantages of respective and the scope of application,
A kind of method is used alone and is extremely difficult to processing requirement, the method being typically combined using several handling process to handle sewage
To handle extraction sewage, so as to reach, cost is low and the purpose of high treating effect.
In order to solve the deficiency of traditional oil-containing sewage treatment technique, what reply every profession and trade proposed to oily waste water treatment newly chooses
War, scientific research personnel start air supporting choosing being combined with cyclone separation process, achieve gratifying achievement in research.Use centrifugal force
Has the history of more than 90 years so far to strengthen pneumatically supported idea, the cyclone air-flotation technology of early stage is mainly by using aerated water
Power cyclone, hydrocyclone is combined with froth flotation, and be applied in the mineral floating of subparticle.From 20 generation
Record since the eighties, researchers attempt to be applied to water-oil separating again.With the continuous research of domestic and international researcher, pass through
Eddy flow and air flotation technology are combined, have developed a kind of compact cyclone air-flotation device (CFU).
The research of cyclone air-flotation technology abroad is more early, and mainstream product has Epcon Offshore AS companies of Norway
Compact air-floating apparatus (CFU), the CFU of TS-Technology AS companies of Norway, the CrudeSep of U.S. CE TCO Technology A. S., U.S.
State Natco Group VersaFlo, the DeepSweep of Cyclotech companies of Britain, OpusMaxim companies of Britain it is compact
Type air-floating apparatus, the VorSep of German Siemens companies, French Veolia Water Solutions＆Technologies
(VWS) Cophase of Westgarth companies etc., it is later compared to foreign countries, the domestic research to cyclone air-flotation technology, it is main at present
The desk research stage is rested on, does not realize large-scale industrialization really, main research unit has：Beijing petrochemical industry
Institute, mechanics study institute of the Chinese Academy of Sciences, Shenzhen Ju Tao companies, Asia environmental protection company, Tianjin Rigid Technology Co., Ltd., Jiang Chenghuan
The units such as guarantor company have compared with in-depth study to cyclone air-flotation.
Conventional cyclone air-flotation device is a kind of fixation kit design, mainly including tank body, stabilizing feed well, tangential inlet, row
The part such as hydraulic fluid port, discharge outlet, flow deflector, (or flow directing nozzles) forms, and existing many scientific research personnel are according to initial eddy flow at present
Air-floating apparatus design improvement Cheng Xin cyclone air-flotation device has simultaneously applied for patent, but the operation principle of device is roughly the same.Its work
It is to import gas (oil field is often with natural gas or nitrogen) in equipment entrance pipeline to make principle, makes to produce substantial amounts of microbubble in water,
To form water, gas and the three-phase mixture for being removed material, in many kinds of force such as interfacial tension, microbubble buoyancy and hydrostatic pressure differences
Collective effect under, promote microbubble be attached on small oil droplet, formed density be less than water mixture, so as to force to float
To sewage surface.Oil-polluted water enters in tank from tangential inlet, and more soft rotation is formed under the guiding of entrance spiral guide sheet
Stream motion, centrifugal acceleration are generally 8-10 times of acceleration of gravity.At the same time, because rate of flow of fluid rise causes fluid pressure
Power declines, and the gas that is partly dissolved of the residual in oil-polluted water is discharged in the form of bubble.From the patent and phase applied at present
From the point of view of closing document report, conventional cyclone air-flotation device, which generally requires plural serial stage, can just reach preferable treatment effect, more
Level series connection adds the floor space of equipment, and this is restricted for being promoted in the limited offshore platform of occupation area of equipment,
This is also that test effect meets to require and fail a main cause of further genralrlization at the scene for most of research institution；With
Oil field is continually developed, and heavy oil field and the poly- oil field of note are continuously increased, and single tank single-stage cyclone air-flotation device is for heavy oil greasy dirt
Water, the treatment effect containing poly- oil-polluted water and unobvious；When designing cyclone air-flotation device, often for the life of subject oil field
Production situation is designed, and the oil field that cyclone air-flotation device changes greatly for non-targeted oil field and treating capacity and water quality is complicated adapts to
Property is poor.
The content of the invention
Patent of the present invention is to carry out optimization design on traditional cyclone air-flotation device basic, there is provided a kind of stabilizing feed well can
Single tank twin-stage cyclone air-flotation device of regulation, adjusted using adjustable stabilizing feed well upper inside single tank twin-stage cyclone air-flotation device
Departmental level Disengagement zone and the space proportion in bottom the second-order separation area, so that cyclone air-flotation device can adapt to more wide in range stream
Amount fluctuation, adapts to the requirement of Oil Field produced water treatment.Patent of the present invention has that compact-sized, separative efficiency is high, using model
The features such as wide, cost-effective, simple to operate is enclosed, can be applied to processing and land multi-purpose station, the petrochemical plant of offshore platform recovered water
Deng oil-polluted water processing.
