Description
Technical field
It the utility model is related to a kind of knockout applied to coal bed gas well head.
Background technology
Coal bed gas gas production wellhead is frequently accompanied by condensate while produced during mining outlet, winter environment temperature compared with
Frozen block easily occurs when low, influences defeated outside coal bed gas and well site gas electricity generator and normally supplies；If condensate is largely gathered in
In gas gathering line, condensate is deposited on the low-lying place of pipeline, can also influence overall coal bed gas conveying；Prior art is typically in gas production
Well head installs separation equipment, and such as liquid separation bag at the low-lying place of gathering line, it is necessary to install condenser cylinder class condensate water collecting and row
Device is put, liquid separation bag is all installed in each well site, and investment cost is big, with high costs；Condenser cylinder is installed in gas gathering line many places, daily
Safeguard potential safety hazard that is cumbersome, and adding gathering line.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of knockout that can separate liquid in coal bed gas.
Knockout of the present utility model, including the cylinder with L-shaped structure, it is characterised in that：The L-shaped structure cylinder
Horizontal segment trailer is the coal bed gas entrance for being mixed with aqueous, and horizontal segment enters vertical section by right-angle turning, and vertical section upper end is
Coal bed gas exports；Leading portion is provided with inclination sieve plate inside horizontal segment, and epimere is provided with umbrella shape sieve plate inside vertical section, and horizontal segment is set
It is equipped with the drainpipe stretched into inside horizontal segment；Drainpipe lower end is located at horizontal segment bottom, and upper end is stretched out outside horizontal piece housing simultaneously
It is provided with valve；
Arc transition is formed by fire bending elbow at the L-shaped structure cylinder right-angle turning；
The L-shaped structure cylinder, drainpipe material are seamless steel pipe.
Knockout of the present utility model, by the condensate of well head mining output and coal bed gas separate and condensate outside
Row, reduce gas gathering line condenser cylinder installation number, save production cost, reduce gas gathering line operation risk, disclosure satisfy that
Coal bed gas well head produces condensation water separation requirement, solves the problems such as coal bed gas well head technological process winter frozen block, ensure that well
Field gas electricity generator normally supplies operation.
Brief description of the drawings
Fig. 1 is the knockout planar structure schematic diagram of the utility model embodiment.
Embodiment
As illustrated, a kind of knockout, including the cylinder with L-shaped structure, the afterbody of horizontal segment 2 of L-shaped structure cylinder are
The coal bed gas entrance 1 of aqueous is mixed with, horizontal segment 2 enters vertical section 7 by right-angle turning, and the upper end of vertical section 7 is that coal bed gas goes out
Mouth 9；The inside leading portion of horizontal segment 2, which is provided with, tilts sieve plate 5, and the inside epimere of vertical section 7 is provided with umbrella shape sieve plate 8, and horizontal segment 2 is set
There is the drainpipe 3 stretched into inside horizontal segment 2；The lower end of drainpipe 3 is located at the bottom of horizontal segment 2, and upper end is stretched out outside the housing of horizontal segment 2
And it is provided with valve 4；Arc transition, L-shaped structure cylinder, draining are formed by fire bending elbow at L-shaped structure cylinder right-angle turning
Tube material is seamless steel pipe.
Knockout of the present utility model, choose sheet of 20# seamless steel pipe of the design pressure for 1.6MPa as this knockout
Body, whole knockout are made up of the cylinder of L-shaped structure horizontal segment, two straight lengths of vertical section and 90 degree of fire bending elbows, will
The long DN15 seamless steel pipes of 1.5m control draining as drainpipe insertion knockout horizontal segment bottom using DN15 ball valves；Knockout
Set up respectively inside horizontal segment, vertical section and tilt sieve plate, umbrella shape sieve plate；Knockout is frozen with gathering and transportation technology placed in series, embedment
Below soil layer, DN15 ball valves basset more than 60 centimeters；After well head output coal bed gas enters knockout with condensate, pass through altogether
Gas-liquid separation three times：
It is gravity settling separation first：When coal bed gas and condensate fluid-mixing run into the tilted sieve plate of knockout, due to
Gas is different from the density of liquid, and for liquid when flowing with the gases, liquid can be affected by gravity, produces one downwards
Speed, and gas still flows towards original direction, that is to say, that liquid separates with gas in gravitational field,
Downward liquid is attached on inclined screen wooden partition face to be collected to knockout bottom.
Then baffling separation is carried out：Coal bed gas after first separation continues to flow forward, by 90 degree of elbows, due to
Gas is different from the density of liquid, and when liquid flows together with gas mixing, if running into stop, gas is understood baffling and walked, and
Liquid continues have a speed forward due to inertia, liquid forward be attached to stop on wall due to gravity effect to
Under be pooled to knockout bottom.
Finally carry out separating umbrella separation：Because gas is different from the particle size of liquid, liquid passes through together with gas mixing
Flowed up after crossing 90 degree of elbows, by the umbrella shape sieve plate at the top of knockout, the same as sieving, gas passes through, and liquid
It is intercepted and stays on umbrella cover, and under gravity downstream to knockout bottom.
After the coal bed gas of well head extraction enters knockout with condensate fluid-mixing, amount to and pass through gas-liquid separation three times, point
The condensate separated out is gathered in knockout bottom, by periodically opening the DN15 ball valves on knockout, utilizes gas in knockout
Condensation water is discharged knockout by pressure.
Knockout of the present utility model, by the condensate of well head mining output and coal bed gas separate and condensate outside
Row, it disclosure satisfy that coal bed gas well head produces condensation water separation requirement, solve coal bed gas well head technological process winter frozen block etc. and ask
Topic, gas electricity generator tight gas supply the problems such as, and it is simple in construction, manufacture it is easy for installation, cost is cheap, has saved production cost,
Meet coal bed gas low cost exploitation to require, while reduce gas gathering line condenser cylinder installation number, reduce gas gathering line operation
Risk, have a extensive future.After knockout is succeeded in developing, have been used in the production of Yanchuan south coal bed gas well site, by field application,
It disclosure satisfy that coal bed gas well head produces condensation water separation requirement, solve the problems such as well head technological process winter frozen block, ensure that
Well site gas electricity generator normally supplies operation.
