Description
Technical field
This utility model patent relates to the device suppressing processed oil pipeline conveying surge pressure, belongs in petroleum industry
Oil and gas pipes transportation art.
Background technology
During the stopped flow injection analysis of product transportation valve, often cause the oil product surge pressure to valve,
Excessive surge pressure can cause the superpressure of pipeline, noise, evacuates and vibrate, and causes oil pipeline performance to reduce
And structural deterioration, and superpressure/air pocket at valve and in pipeline, can be formed, cause the distortion of pipeline wall to become
The conveying equipment such as shape and spool lost efficacy, thus caused leakage of oil, pipeline to suppress the accident such as leakage；Domestic product transportation pipe
Road is a complicated pipe communication system, completely used closed conveying technique, its transporting oil be divided into diesel oil,
The multiple fluid oil products such as gasoline, much more complicated than crude oil pipeline of operational management, only take course of conveying
Centralized dispatching Automated condtrol, the safe efficient operation of guarantee pipeline；Due to the pipeline shutdown that takes place frequently again
Start, cause in the course of conveying of product oil, at valve, produce surge pressure, conventional oscillation suppression pressure
Method uses and slowly closes valve, although can avoid surge pressure, but delay closing valve time so that transfer efficiency drops
Low.
Utility model content
For above-mentioned technical problem, this utility model patent proposes one suppression processed oil pipeline conveying surge pressure
Devices and methods therefor, realized the suppression of surge pressure by tank body duplex device.
The device of suppression processed oil pipeline conveying surge pressure, including surge pressure suppression tank and knockout drum；
Air filter connects inflator pump, and inflator pump is connected with surge pressure suppression tank by check-valves, surge pressure suppression tank
The interior side set fall that is provided with straggly hinders batten, and surge pressure suppression tank has suppression pressure tank table；In knockout drum
There is gas liquid separating filtering aperture plate；Gas-liquid separation pot bottom has flushbottom tank valve, top to have knockout drum Pressure gauge,
Top connects atmospheric valve also by ball valve；Main pipeline is respectively by the first flat gate valve with surge pressure suppression tank even
Connecing, surge pressure suppression tank is connected with knockout drum, and the outlet of knockout drum connects the 3rd Flat Sluice
Valve；Main pipeline is connected with the outlet of knockout drum also by the second flat gate valve；Surge pressure suppression tank and
Knockout drum is fixed by disjunctor fixed support；Two tank bottoms support respectively.
The suppressing method of the device of suppression processed oil pipeline conveying surge pressure:
(1) close the second flat gate valve, open the first flat gate valve；Product oil enters fluctuation by main pipeline
Pressure restraining tank；
(2) inflator pump injects gas, the gas in surge pressure suppression tank and mistake to surge pressure suppression tank
Tooth fall resistance batten is used for slowing down surge pressure amplitude；
(3), during product oil enters back into knockout drum, gas liquid separating filtering aperture plate, by gas from product oil
In separate, product oil is flowing out from the outlet of knockout drum.
Due to the flow instabilities process of product oil, kinetic energy is converted to pressure potential, product oil during conversion
Pipeline at valve is carried out filling, compression, and the time of filling is that pressure velocity of wave is determined, therefore by filling
Enter gas, reduce pressure velocity of wave, so that loading time extends, reduce the surge pressure suffered by product oil and make
With；Surge pressure is mainly under pressure the impact of velocity of wave and frictional resistance, and this utility model utilizes and is mixed into gas phase
Affect pressure velocity of wave, affect frictional resistance by side set fall resistance batten, can effectively surge pressure potential energy be disappeared
Consumption is in the compression and frictional resistance of gas.
The device of the suppression processed oil pipeline conveying surge pressure that this utility model patent provides, simple to operate, peace
Dress is convenient, low cost, can be applied not only in the surge pressure suppression of product oil it can also be used to aqueduct
In the suppression of water attack.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model patent is described further, but this utility model patent is not limited to
In following example:
