Detailed description of the invention
For the openest technical scheme, below in conjunction with Figure of description, it is elaborated by embodiment:
With reference to Fig. 1,2,3,4, the present invention relates to a kind of plug flow trapper for oil/gas mixed transport section device for trapping slug flow, mainly
By housing 8, TP board component 9, whirl cylinder 6, vortex broken device 14, downspout 12, gas outlet 11, liquid outlet 3, sewage draining exit 15, peace
Full valve 7, liquidometer/fluid level transmitter 2, Pressure gauge 10, manhole 13 form.
A kind of whirl slug flow catcher, is provided with gas feed, described gas including housing, in the housing portion's tangential direction
In whirl cylinder 6, the housing 8 internal upper part gas compartment are installed in the housing 8 at import 5, the TP board component 9 with radial passage is installed.
Slug flows through gas feed 5 and tangentially enters each cyclone pipe 18 of whirl cylinder 6, carries out cyclonic separation.Drop therein
Along cyclone pipe 18 inwall to congregate, gas along cyclone pipe 18 central upward flow, enters and has footpath described in housing upper
To the TP board component 9 of passage.
This catcher uses vertical structure, can effectively increase the slug flow flowing space in short transverse, extension plug flow
Middle gas phase and the flowing time of liquid phase, can be effectively improved liquid phase separation efficiency, eliminates slug flow.At described gas feed 5
Whirl cylinder 6 is installed in housing 8, liquid phase separation efficiency can be effectively improved.Catcher is provided with hanger, and two ends are welded with end socket, middle
Being provided with manhole, inside is provided with cat ladder, uses skirt to support.
As it is shown on figure 3, described whirl cylinder 6 is made up of some cyclone pipes 18；Have in air inlet pipe at gas feed 5 with
Cyclone pipe (breach that 8 phases are passed through, this breach backing plate welded around 19 are provided with gripper shoe 20 and connecting plate 21 on backing plate 19,
Having bolt hole on connecting plate 21, cyclone pipe 18 is installed in the breach of gas inlet tube 5 by bolt 22 and described connecting plate 21
Position.When slug flow flows through described gap position, can tangentially enter cyclone pipe 18 and carry out cyclonic separation.This structure is installed
Convenient, detachable.
The described TP board component 9 with radial passage, its center is gas passage, and top is provided with baffle plate 17, and bottom is provided with
Downspout 12.Gas enters behind upper gaseous phase space, can only change direction and pass radially through TP plate to surrounding along housing, from TP plate with
The gap of inner walls flows up.This structure increases the layout of TP plate, increase gas filtration space, and be varied multiple times
Gas flow direction, can effectively trap the drop carried secretly in exit gas.
In described housing 8, bottom is fluid space, installs vortex broken device 14 in this fluid space.
Described housing 8 top is provided with gas outlet 11, and pressure transmitter is installed on housing 8 top at gas outlet 11
10, bottom housing 8, lowest part is provided with sewage draining exit 15；Relief valve 7 is installed on the housing 8 at described TP board component 9；Described liquid
Liquidometer/fluid level transmitter 2 is installed on the housing 8 at space；Housing 8 bottom sides installs liquid outlet 3.
Its operation principle of whirl slug flow catcher and work process be: gas enters inside container through gas feed 5,
Porch sets whirl cylinder 6, when gas flows through cyclone pipe 18, enters cyclone pipe along tangential direction, and forms eddy flow, produces proportion
The centrifugal force that power is high times, owing to gas, liquid density is different, the difference of suffered centrifugal force is very big, gravity, centrifugal force and
Gas and liquid being separated under the comprehensive function of buoyancy, liquid is radially pushed to outside, and discharges from leakage fluid dram downwards, and gas
Then move to the center of catcher, and upwards arrive the gas compartment.After gas is full of admission space, owing to plate washer 17, gas are arranged at top
Body can only change direction and pass radially through TP plate to surrounding along housing, flows up from the gap of TP plate with inner walls.Passing through
During TP board component 9, air-flow constantly changes direction, and small drop constantly collides with each other, and constantly coalesces on TP board component 9 surface,
Form bigger drop, collected in the bottom of container by collector tube 12, discharged by liquid outlet 3, become by liquidometer/liquid level
Sending device 2 can show liquid level, liquid level signal is delivered to Central Control Room centralized Control by fluid level transmitter, can automatically set by Liquid level
Scope.The impurity such as solid particle can be discharged by sewage draining exit 15, and sewage draining exit 15 is provided with vortex broken device 14 in case producing vortex.Gas leads to
Cross after TP board component 9 takes off liquid, be full of air outlet space, flow out through gas outlet 11.It is provided with relief valve 7 on admission space top, can
Carrying out overpressure protection, be provided with the controlled mouth pressure of making of pressure transmitter 10 on air outlet space top, skirt 1 is the base of housing,
Interior cat ladder 4 is the installation of slug catcher for convenience and maintenance and arranges, and this device can realize automatically connecting of gas
Continuous gas-liquid separation and slug flow effectively trap elimination.
