16 inner wall accelerates the gas-liquid separation of gas-liquid mixture, improves the dewatering speed and dehydrating effect of gas-liquid mixture.It is got rid of
Continue to move along dehydrating tube 16 to the liquid of 16 inner wall of dehydrating tube, after reaching 16 tail portion of dehydrating tube, be entered by second entrance
Then diversion chamber 17 enters setting between cycle eddy flow dehydration device 4 and second liquid phase capturing device 6 by inlet 10
Liquid collecting room 9 in, be finally discharged by second liquid phase capturing device 6, and pass through dewatered gas then pass through recycle eddy flow dehydration
The exhaust outlet of device 4 enters downstream chamber 8, is finally discharged by first outlet 7, passes through second entrance by dewatered gas
When, diversion chamber 17 is entered under the action of 17 negative pressure of diversion chamber, carries out secondary gas-liquid separation.
The guide vane 19 is equipped with multiple.It, can be according to the difference of acquired eddy flow centrifugal intensity in dehydrating tube 16
Multiple guide vanes 19 are set on water conservancy diversion axis 18, and the number of the guide vane 19 is 4,6,8 or 12.Foundation is led
The space size between axis 18 and 16 inner wall of dehydrating tube is flowed, 4~12 guide vanes 19 can be set, to increase gas-liquid mixture
With the contact area between cycle eddy flow dehydration device 4, accelerate dewatering speed, improves dehydrating effect.
Embodiment 4：
As shown in figure 14, the slug catcher 2 be equipped with baffle plate 26, specifically, first entrapment plate 24 with
It is equipped with baffle plate 26 between second entrapment plate 25, baffle plate 26 is set on slug catcher 2, it can be right in slug catcher 2
Into after the slug flow trapping of drain sump, slug flowing is destroyed, the dehydration efficiency to gas-liquid mixture is improved.As shown in figure 15,
The baffle plate 26 is equipped with multilayer from inside to outside, and setting multilayer baffle plate 26 can improve the destruction dynamics to slug flow, make section
Plug flow destroys more complete.
Embodiment 5：
As shown in Fig. 3 and 16, slug arrester 14 is equipped in the slug dust trapping chamber 11, slug arrester 14 is arranged in section
Dust trapping chamber 11 is filled in close to one end of slug catcher 2, and slug arrester 14 is welded by multiple tablets according to certain angle, more
The setting of a tablet undulate, the top of slug arrester 14 are h3 away from the distance of partition board 3, and the lower end of slug arrester 14 is away from de-
The distance of water pot inner wall is h4, and distance h3 of the top away from partition board 3 of slug arrester 14 is set according to the treating capacity of gas-liquid mixture
Fixed, when the treating capacity of gas-liquid mixture is high, the distance of h3 is small, and when the treating capacity of gas-liquid mixture is low, the distance of h3 is big, together
When slug arrester 14 lower end set according to gas-liquid mixture liquid content away from the distance h4 of dehydration top tank structure, work as liquid content
The distance of Gao Shi, h4 are big, and when liquid content is low, the distance of h4 is small.Slug arrester 14 is set, slug flow can be made gradually to disappear
It loses, forms stratified flow, keep the gas-liquid separation effect of gas-liquid mixture more notable.
A kind of operational process of the anti-slug eddy flow dehydration device of high-liquid-ratio gas well well head is as follows：
As shown in figure 4, gas-liquid mixture enters from first entrance 1 in drain sump, compartment 13 is arrived first at, in compartment
In 13 after the trapping of slug catcher 2, liquid under the effect of gravity, while falling under the action of slug catcher 2, into every
The slug dust trapping chamber 11 of 3 lower section of plate, and gas then enters the dewatering station 12 of 3 top of partition board, thus realizes gas-liquid mixture
Gas-liquid separation for the first time, the liquid after separation are discharged through the first liquid phase capturing device 5, and the gas after separation enters dewatering station 12, this
When, moisture can be contained in gas, gas enters cycle eddy flow dehydration device 4 under the action of air-flow and carries out second dehydration, specifically
, gas enters dehydrating tube 16, is flowed along dehydrating tube 16 under the action of air-flow, when by water conservancy diversion axis 18, in water conservancy diversion leaf
So that air-flow is generated rotation in dehydrating tube 16 under the action of piece 19, rotating flow is become from axial circulation, i.e., by along 16 axis of dehydrating tube
The axial flow of line direction movement is changed into the swirling eddy rotated around 16 axis of dehydrating tube, at this point, air-flow generates tangential velocity,
It is rotated around the axis of dehydrating tube 16 in dehydrating tube 16, air-flow is made to generate centrifugal force, under the influence of centrifugal force, the liquid in gas
Body (including heavy phase liquid water and part heavy constituent) is thrown toward the inner wall of dehydrating tube 16, makes the gas (gas-liquid for the first time containing moisture
Gas after separation) realize that secondary gas-liquid separation, the gas after secondary separation enter downstream chamber 8 through dehydrating tube 16, finally by
First outlet 7 is discharged, and the liquid that 16 inner wall of dehydrating tube is thrown toward after secondary separation continues to flow along the inner wall of dehydrating tube 16, through de-
The second outlet 15 of 16 tail portion of water pipe enters in diversion chamber 17, and the inlet 10 then through 17 bottom of diversion chamber enters liquid collecting room
9, most afterwards through the discharge of second liquid phase capturing device 6, and enter at this time in diversion chamber 17, also portion gas, into diversion chamber
Gas in 17 then passes sequentially through circulation pipe 20 and water conservancy diversion axis 18, is again introduced into dehydrating tube 16 and is dehydrated.
As shown in figure 5, the power resources of cycle eddy flow dehydration device 4：When gas enters dehydrating tube under the action of air-flow
After 16, when by water conservancy diversion axis 18, negative pressure, the cycle being connected at this time with water conservancy diversion axis 18 are generated in water conservancy diversion axis 18 under the action of air-flow
It is negative pressure in pipe 20 and diversion chamber 17, negative pressure is also generated at the second outlet 15 of 16 tail portion of dehydrating tube, under the action of negative pressure
Gas in dehydrating tube 16 enters diversion chamber 17, completes the cycle in cycle eddy flow dehydration device 4.
