Description
Technical field
The invention belongs to petrochemical industry, ore dressing, two-phase laminated flow, environmental protection technical field, particularly to centrifugal point of a kind of eddy flow
From method and apparatus.
Background technology
A lot of industrial process or be in technique and need or the equipment that is in runs and needs or be in environmental protection and need to relate to two-phase or multiphase and separate.
Typical two-phase laminated flow process has gas to separate with catalyst fines, gas-liquid separation, water and separating of oil, water or oily thin with catalyst
Powder separation etc..
It is designed with catalyst fines recvery facility with reactor, the regenerator of catalyst fines fluidization operation, generally uses whirlwind
Separator.The reactor of device, the regenerator such as catalytic cracking (FCC), methanol-to-olefins (MTO) generally use PV type whirlwind at present
Separator or other modified model cyclone separator, be made up of inlet tube, cylinder, cone cylinder, ash bucket and dipleg, it is characterized in that containing thin
Powder gas tangentially enters cylinder from 1 entrance, is rotated into row centrifugation in cylinder, cone cylinder, reclaims fine powder and falls into
Ash bucket is discharged through dipleg, purifies gas and discharges from central upper portion exhaustor through device interior center stream.Conventional cyclones is only
1 gas access, when device diameters is bigger there is obvious current gradient (reducing successively) in 4 quadrants, and this will make equipment imitate
Rate reduces and causes gas-solid disngaging efficiency to reduce.The device such as catalytic cracking, methanol-to-olefins is additionally provided with three-stage cyclone separator, closely
Within several years, develop " willy-willy " formula three to revolve, make three-stage cyclone separator structure significantly simplify, be easy to manufacture and safeguard.Many institutes
Known three-stage cyclone separator carries out ultra acelerator fine particle gas solid separation, and " willy-willy " separator relative diameter is relatively big and only has
1 gas access, its gas-solid disngaging efficiency the highest (general only about 80%).
Gas-liquid two-phase separates the most universal, and process gas medium is cooled to 40 DEG C of entrance gs-oil separators, at oil gas
Separator carries out air-liquid natural subsidence separation, it is commonly known that natural subsidence separation efficiency is the highest, it is desirable to strict technical process
If gas band liquid seriously will affect normal operating, need to arrange high efficiency separation equipment as supplementing and to ensure process optimization.
A lot of technical processs also have fresh water (FW) or sewage to discharge, and the gas medium containing steam cycle is condensed is cooled to 40 DEG C of entrance oil gas
Separator, carries out oil gas, liquid phase oil product and water natural subsidence at gs-oil separator and separates, and water is discharged through point water bag.Due to a point water
Inclusion amasss little, natural subsidence separation therefore inefficient, discharges water often band Chuck Steak, on the one hand causes product to lose, the opposing party
In the face of lower procedure adversely affects, as the sewage more containing light oil enters sewage stripping device, in addition to affecting normal operating,
Also can cause safety problem.It is thus desirable to the separating of oil equipment of High-efficient Water.The example of another 1 oil-water separation is catalysis, coking plant divides
Evaporate top pumparound oil often band water, cause fractionating column top salt crust, affect fractionating column normal operating.Some devices are provided with
Drain sump, employing natural subsidence separation equipment volume is big, separation efficiency is the highest.Need online high efficiency oil-water separation equipment by tower top
It is properly functioning that the moisture content that circulating reflux oil carries effectively removes guarantee device.
Catalytic cracking unit circulation slurry oil contains catalyst fines, when level of catalyst fines height except increasing recycle oil stock pump, changing
Outside hot equipment attrition also can increase circulation slurry oil scaling, coking tendency, affect heat transmission equipment heat-transfer effect, equipment life and
Fractionating system safe operation.Downstream user can be affected during externally extracting oil level of catalyst fines height use, owing to slurry oil viscosity is big,
Temperature height conventional equipment separating catalyst fine powder is abnormal difficult.It is thus desirable in special online high efficiency separation equipment removing circulation slurry oil
Catalyst fines or reduce circulation slurry oil in level of catalyst fines.Methanol-to-olefins device technique process produces a large amount of moisture content,
Reaction gas, water vapour carry a small amount of catalyst fines and flow out together, carry out chilled water (chw) and wash after heat exchange is lowered the temperature, most of water vapor
Condensing and wash the catalyst fines carried, fresh water (FW), a small amount of oil and catalyst fines are discharged together, need to separate through high-efficiency three-phase
Equipment processes.
