Embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.
As shown in drawings, a kind of light hydrocarbon oil extraction element of the utility model, it has gas compressor fraction 51 fraction, the outlet of gas compressor is connected with the import of water cooler fraction 52 fraction, the outlet of water cooler is connected with the import of interchanger fraction 53 fraction, the outlet of interchanger is connected with the import of gas-liquid separator fraction 55 fraction, the import and export of unit cooler fraction 54 fraction goes out with the cooling fluid of interchanger respectively, import is connected, and the gas-liquid separator bottom has liquid to go out to manage fraction 56 fraction.
During use, Sweet natural gas enters gas compressor, Sweet natural gas is compressed, produce high temperature, utilize water cooler, interchanger that Sweet natural gas is cooled off then, its temperature is reduced to-3--6 degree centigrade, enter gas-liquid separator again and carry out gas-liquid separation, isolated fraction goes out pipe from liquid discharges, and Sweet natural gas can further be utilized after gas-liquid separator is discharged.
The outlet of described gas-liquid separator fraction 55 fraction is connected with the import of another gas-liquid separator fraction 57 fraction, and the bottom of another gas-liquid separator has another liquid to go out to manage fraction 58 fraction.Utilize two gas separators to can further improve extraction effect.
As Fig. 2, shown in Figure 3, the use principle of the gas-liquid separator in the utility model is, to send into from inlet pipe through overcooled Sweet natural gas, the natural gas via induction pipe is walked downwards, thread groove rotation along the induction pipe internal surface in the walking process is downward, the part fraction that contains in the Sweet natural gas is got rid of on the induction pipe internal surface, and then flows downward, and falls housing bottom.The Sweet natural gas that comes out from induction pipe further flow to air inlet port 5, and in this course, the part fraction that contains in the Sweet natural gas is hung by the net sheet and clung, and accumulation drops onto housing bottom more for a long time.The natural gas via air inlet port flow to below another baffle plate, and the part fraction that wherein contains is hung by another net sheet and clung, and accumulation is fallen on the baffle plate 6 more for a long time, and flow to air inlet port and fall along baffle plate.Sweet natural gas continues upwards to flow, and discharges from escape pipe through the 3rd net sheet, and the small part fraction that wherein contains is hung by the 3rd net sheet and clung, and accumulation falls more for a long time.Like this, natural gas via is crossed separating for several times, and the most fraction that wherein contain are that liquid alkane compositions such as propane, butane, pentane are separated.
There is third gear plate 9 outside of the induction pipe 1 between described baffle plate 6, another baffle plate 15, the 4th net sheet 8 is arranged below the third gear plate, and there is another air outlet 2 at the position away from air inlet port 5 of third gear plate, the 4th net sheet.During use, Sweet natural gas obtains the further separation of the 4th net sheet, has improved separating effect.
In described induction pipe 1 newel 21 is arranged, the outside surface of newel has another thread groove 22.Like this, the rotation of the Sweet natural gas in the induction pipe is stronger, and separating effect is better.
In communicating pipe 11 below described the 3rd net sheet 12 a plurality of small front aprons 10 are arranged, walk pore 19 on each small front apron respectively.Like this, be subjected to stopping of each small front apron in the Sweet natural gas walking process, slow down lift velocity, be convenient to the separation of the 3rd net sheet.Obviously, the pore of walking on each small front apron is crisscross arranged.
Described housing 3 is fixedly formed by loam cake 31, drain pan 33 and 32 butt joints of intermediate cylinder between the two.At this moment, can adopt ring flange, bolt connecting mode.Like this, can easily housing be taken apart, improve the more accessibility of remedial operation such as draping sheet, avoid existing separator to need electrosgas welding and the danger brought.
Described baffle plate 6, another baffle plate 15 tilt to be installed in the housing.The angle of inclination of two baffle plates is opposite.Can play the guiding function to natural gas flow like this, the existence on inclined-plane has also improved the separating area and the separating effect of net sheet.
