Description
Technical field
This utility model belongs to petroleum gas field, is specifically the gas of gas hydrates experimental loop device
The liquid removing device of body closed circuit.
Background technology
Patent CN104634931A " gas hydrates experimental loop device ", in this experimental loop device,
In order to make full use of the natural gas having neither part nor lot in reaction, the pressure in Simultaneous Stabilization loop, devise a kind of gas and follow
Loop back path.Gas hydrates experimental loop device is as it is shown in figure 1, natural gas enters reactor and water from bottom
Carry out lanthanum chloride hydrate reaction under certain condition.The unreacted natural gas of part passes through pipeline from reactor top
Enter gas circulation loop.
Gas circulation loop includes compressor, reactor, effusion meter, pipeline, valve and corresponding temperature, pressure
Power indicator.When the gas pressure in gas circulation loop is too high, for the pressure in stable loop, need to open
The vacuum pump of experimental loop, by the manostat in unnecessary gas suction to system.When pressure reaches requirement of experiment
Time, stop bleeding.In like manner, when the gas pressure in gas circulation loop is too low, need to open in experimental loop
Plunger displacement pump, by the water suction manostat in water tank, utilize the compressibility of gas so that the pressure in loop
Constantly increase.When reaching experimental pressure requirement, stop compressed gas.
Natural gas in gas circulation loop is unreacted natural gas in reactor, and it can be taken in uphill process
Liquid in band portion reactor enters pipeline, and the water carried can be to follow-up equipment and the stable fortune of whole system
Row causes and has a strong impact on, and shortens the service life of equipment, can be substantially reduced in experiment measuring gas flow rate simultaneously
Accuracy.
Utility model content
For the problems referred to above, this utility model provides one to be applicable to patent CN104634931A " gas water
Compound experimental loop device " in the liquid removing device of gas circulation loop, by gas hydrates compound experiment device
Gas circulation loop in the moisture that carries remove.
The liquid removing device of gas circulation loop: include that liquid collecting water tank, liquid collecting water tank are connected to sky by input duct
So gas hydrate compound experiment device gas circulation loop system lowest part, input duct is provided with liquid flowing valve；
Liquid collecting water tank bottom passes through Drainage pipe connected drainage valve；Differential pressure transmitter is by connecting pipe with liquid collecting water tank even
Connect.
The liquid removing method of the liquid removing device of gas circulation loop: isolated liquid warp in gas circulation loop system
Cross input duct enter liquid collecting water tank, when liquid collect a certain amount of after, Drainage pipe discharge.
This utility model is realized in except liquid function:
The liquid removing device of gas circulation loop is arranged on the lowest part of gas circulation loop system, in order to liquid enters
Enter input duct.Density due to liquid is much larger than the density of natural gas, during liquid gas coming through closed circuit,
Under gravity, liquid enters liquid collecting water tank through input duct and liquid flowing valve.Liquid in liquid collecting water tank
Reach a certain amount of after, open draining valve, liquid is discharged via Drainage pipe and draining valve.Differential pressure transmitter
It is connected with liquid collecting water tank by connecting pipe, for measuring the top and the bottom pressure differential of liquid in liquid collecting water tank.
The liquid removing device of the gas circulation loop that this utility model provides, can effectively remove in natural gas closed circuit
The moisture carried, thus increase the safety and stability of experimental system, also improves in service life of extension device
The accuracy of this gas circulation loop system measurement data.
Accompanying drawing explanation
Fig. 1 is the structural representation of gas hydrates experimental loop device；
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
This utility model is further illustrated below by embodiment.
As in figure 2 it is shown, the liquid removing device of gas circulation loop, including liquid collecting water tank 1, liquid collecting water tank 1 passes through
Input duct 5 is connected to gas hydrates compound experiment device gas circulation loop system lowest part, feed tube
Liquid flowing valve 2 it is provided with on road 5；By Drainage pipe 6 connected drainage valve 3 bottom liquid collecting water tank 1；Difference
Pressure transmitter 4 is connected with liquid collecting water tank 1 by connecting pipe 7.
For ensureing that liquid can enter liquid collecting water tank 1 smoothly, input duct 5, Drainage pipe 6 use Φ's 19 × 3
Seamless steel pipe.Connecting pipe 7 uses the connecting pipe of Φ 10 × 1.5, and pipe material is 0Cr18Ni9.
The effect of liquid collecting water tank 1 is to collect a certain amount of liquid and discharge it, for cost-effective, and liquid collecting water tank
It is designed to slim-lined construction, uses seamless steel pipe and Plate Welding all-in-one-piece mode.Seamless steel pipe uses Φ 54 × 3
Stainless steel tube, a length of 600mm, steel plate thickness 3mm, steel pipe and steel plate all use 0Cr18Ni9 material
Matter.
4 pressure measurement differences of differential pressure transmitter are at about 6KPa (△ p=ρ g △ h, △ h=600mm), therefore, and choosing
With range ability 0～100KPa differential pressure transmitter.Select Honeywell ST3000 series
STD924-A1A-00000-MB, SM, 1C type differential pressure transmitter
The main design parameters of this liquid removing device is:
Design temperature :-20～60 DEG C；
Design pressure: 12MPa；
Pipe material: 0Cr18Ni9
Water tank material: 0Cr18Ni9
Working media: water, natural gas
This liquid removing device is arranged on the lowest part of gas circulation loop, in order to water enters feed liquor under gravity
Pipeline.It is as follows except liquid stream journey:
(1) differential pressure transmitter 4 first returns to zero；After having returned to zero, differential pressure transmitter 4 is started working, and enters
Row data acquisition；
(2) when collecting liquid, first open liquid flowing valve 2, close draining valve 3.Natural gas in closed circuit
The moisture carried is entered into liquid collecting water tank 1 by input duct 5 under gravity.
(3) differential pressure transmitter 4 can measure the pressure differential of liquid collecting water tank 1 upper limit in real time, when differential pressure transmitter 4
Differential pressure measurement reach set higher limit time, stop collect liquid, by automaton, close into
Fluid valve 2, opens draining valve 3, and liquid is just discharged from liquid collecting water tank 1.
(4) after the water in liquid collecting water tank 1 is all discharged, close draining valve 3, open liquid flowing valve 2,
Again liquid is collected.
Repeat the above steps constantly carries out liquid and collects and discharge opeing process, will constantly remove in gas circulation loop
The liquid carried, thus improve in gas hydrates experimental provision the safety of gas circulation loop system and
Stability, extends the service life of equipment, and improves the accurate of this gas circulation loop system measurement data
Property.
