Specific implementation mode
Further to disclose technical scheme of the present invention, with reference to the accompanying drawings of the specification, it is elaborated by embodiment：
Referring to Fig.1,2,3,4, the present invention relates to a kind of for trapping the plug flow trapper for oil/gas mixed transport section device of slug flow,
Mainly by shell 8, TP board groups part 9, swirl cylinder 6, vortex broken device 14, downspout 12, gas vent 11, liquid outlet 3, sewage draining exit
15, safety valve 7, liquid level gauge/fluid level transmitter 2, pressure gauge 10, manhole 13 form.
A kind of whirl slug flow catcher, including shell, in the housing portion's tangential direction be equipped with gas feed, the gas
Swirl cylinder 6 is installed in the shell 8 at import 5, the TP board groups part 9 with radial passage is installed in the 8 internal upper part gas compartment of shell.
Slug flows through each cyclone pipe 18 that gas feed 5 tangentially enters swirl cylinder 6, carries out cyclonic separation.Drop therein
Along 18 inner wall of cyclone pipe to congregate, gas has diameter along 18 central upward flow of cyclone pipe, into described in upper part of the housing
To the TP board groups part 9 in channel.
The trap uses vertical structure, can effectively increase slug flow in the flowing space of short transverse, extend slug flow
The flowing time of middle gas phase and liquid phase can effectively improve liquid phase separative efficiency, eliminate slug flow.At the gas feed 5
Swirl cylinder 6 is installed in shell 8, liquid phase separative efficiency can be effectively improved.Trap is equipped with lifting lug, and both ends are welded with end socket, intermediate
Equipped with manhole, it is internally provided with cat ladder, is supported using skirt.
As shown in figure 3, the swirl cylinder 6 is made of several cyclone pipes 18；Be provided in the air inlet pipe at gas feed 5 with
Cyclone pipe（The notch that 8 phases are passed through is welded with backing plate 19 around the notch, and support plate 20 and connecting plate 21 are equipped on backing plate 19,
Bolt hole is provided on connecting plate 21, cyclone pipe 18 is installed in the notch of gas inlet tube 5 by bolt 22 and the connecting plate 21
Position.When slug flow flows through the gap position, it can tangentially enter cyclone pipe 18 and carry out cyclonic separation.The structure is installed
It is convenient, detachable.
The TP board groups part 9 with radial passage, center are gas passage, and top is equipped with baffle 17, and bottom is equipped with
Downspout 12.After gas enters upper gaseous phase space, direction can only be changed and pass radially through TP plates along shell around, from TP plates with
The gap of inner walls flows up.This structure increases the arrangements of TP plates, increase gas filtration space, and be varied multiple times
Gas flow direction can effectively trap the drop carried secretly in exit gas.
Lower part is fluid space in the shell 8, and vortex broken device 14 is installed in the fluid space.
8 top of the shell is equipped with gas vent 11, and pressure transmitter is installed on 8 top of shell at gas vent 11

Its operation principle of whirl slug flow catcher and the course of work are：Gas enters by gas feed 5 inside container,
Inlet sets swirl cylinder 6, when gas flows through cyclone pipe 18, enters cyclone pipe along tangential direction, and form eddy flow, generates proportion
The centrifugal force that high times of power, since gas, liquid density is different, the difference of suffered centrifugal force is very big, gravity, centrifugal force and
Gas and liquid are separated under the comprehensive function of buoyancy, liquid is radially pushed to outside, and is discharged from leakage fluid dram downwards, and gas
The center of trap is then moved to, and arrives the gas compartment upwards.After gas is full of admission space, since plate washer 17, gas are arranged at top
Body can only change direction and pass radially through TP plates along shell around, be flowed up from the gap of TP plates and inner walls.Passing through
When TP board group parts 9, air-flow constantly changes direction, and small drop constantly collides with each other, and is constantly coalesced on 9 surface of TP board groups part,
Larger drop is formed, the bottom of container is collected in by collector tube 12, is discharged by liquid outlet 3, is become by liquid level gauge/liquid level
It send device 2 that can show that liquid level signal is sent to Central Control Room centralized control by liquid level, fluid level transmitter, can automatically set Liquid level
Range.The impurity such as solid particle can be discharged by sewage draining exit 15, and sewage draining exit 15 is equipped with vortex broken device 14 to prevent generating vortex.Gas is logical
It crosses after TP board groups part 9 takes off liquid, is full of air outlet space, is flowed out through gas vent 11.It is equipped with safety valve 7 on admission space top, it can
Overpressure protection is carried out, can control outlet pressure, skirt 1 equipped with pressure transmitter 10 on air outlet space top is the pedestal of shell,
Interior cat ladder 4 is arranged in order to facilitate installation and the maintenance of slug catcher, which may be implemented the automatic of gas and connect
Continuous gas-liquid separation and effective trapping of slug flow are eliminated.
