Description
Technical field
The invention belongs to Oil-gas Separation and flow assurance technical field, specifically, is related to a kind of outer-flowing type air separator.
Background technology
Bubble, impurity etc. not only result in flowmeter metering into mass flowmenter is forbidden, more can be to flowmeter internal junction
It is configured to abrasion damage.The flow assurance such as air separator, filter equipment must be added before mass flowmenter with quality assurance flow
The steady accurate measurement of meter.
Air separator and separation equipment in general sense are essentially different, and gravity separator or cyclone separator are directed to
Object be mainly the higher oil gas of gas liquid ratio, gas-liquid is all continuous phase, the liquid phase in the presence of gravity, buoyancy or from power
Mutually separate；And the main function of air separator prevents small to eliminate minute bubbles or the small air mass in liquid phase as dispersed phase
Bubble or air mass enter inside mass flowmenter.
The difference of separation object causes air separator and is generally separated the difference of device separating mechanism emphasis, centrifugal force with again
The effect of power, buoyancy in air separator can not occupy most important status, on the contrary separating mechanism of the overflow separation in air separator
In be indispensable.Overflow separating mechanism is made full use of to optimize great significance for design to air separator internal structure.
CN102225252A discloses a kind of spiral-flow type air eliminator, fluid edge and air separator inner walls phase in the air separator
After the direction cut enters container, flowed in funnelform cylinder internal rotation, gas is assembled to hopper centre and moved upwards, gathers
Collect the top vent of air separator housing, liquid is descending to be discharged by drain pipe, realizes gas-liquid separation.CN202674694U is disclosed
A kind of crude oil pipeline air separator, mainly for separating of and give off the gas mixed in crude oil, its structure mainly includes master
Body structure and air bleeding valve.Above two air separator can discharge the gas in liquid to a certain extent, but degasifying effect is limited.
The content of the invention
It is bad in order to solve degasifying effect existing for prior art, it is difficult to ensure the technical problem of the accuracy of metering, this
Invention provides a kind of outer-flowing type air separator.
Outer-flowing type air separator provided by the invention in vertical outer cylinder body of the both ends with end socket, outer cylinder body mainly by setting

Liquid turns are stable axial movement to eliminate the tangential velocity of fluid in flow field by the main function of rotation fan plate.Spin-ended fan
The fan plate quantity of plate is no less than 3 fans, and very few fan plate quantity is difficult to play a part of eliminating tangential velocity.
Ball-cock assembly is mature equipment, is installed on gaseous phase outlet, and ball float is located on gas-liquid interface.Gas-liquid interface is located at outer layer ring
It is gas phase zone above gas-liquid interface, lower section is liquid phase region in shape space.Gas phase is assembled to a certain extent inside container, gas-liquid
Interface declines, and ball-cock assembly is opened under the drive of float, and gas phase is discharged into blowdown system through gaseous phase outlet.
The general principle of the present invention is that the liquid phase of carrying minute bubbles or small air mass first is set through outer cylinder body bottom bulkhead center
The medium entrance put enters inner barrel；Gas-liquid incoming is moved through spin-ended fan plate steady flow condition from bottom to top in inner barrel；Carry
The liquid phase of minute bubbles along overflow on inner barrel through entering inner barrel and the internal layer annular space of middle cylinder formation, in this process
Middle minute bubbles or air mass buoyance lift enters gas phase zone, is separated for first time overflow；The liquid phase of internal layer annular space is through on middle cylinder
Enter outer annular space along overflow, wherein remaining minute bubbles escape into gas phase zone, separated for second of overflow；Gas phase is gathered
Liquid level declines collection in outer annular space to a certain extent, and air separator ball-cock assembly is opened, and gas phase is discharged into emptying system through gaseous phase outlet
System；Liquid phase after cooling down enters metering system through liquid-phase outlet.
Advantages of the present invention with：Using spin-ended fan plate and the design of three cartridge types, inner cylinder is gradually to outer barrel overflow, in liquid phase
The minute bubbles or air mass of carrying are separated, and improve separating effect, and make it that air separator structure is simpler, and operation is more square
It can lean on.
