Description

Technical Field

[0001] The utility model relates to the technical field of natural gas equipment, and more specifically, to a vertical gas-liquid separator for natural gas. Background Art

[0002] The natural gas vertical separator is to allow natural gas to enter the separator through the gas-liquid inlet for basic phase separation. The natural gas enters the gas channel for gravity sedimentation to separate the liquid droplets, and the liquid enters the liquid space to separate the bubbles and solid impurities. Before leaving the separator, the gas passes through the mist collector to remove small droplets and then flows out from the gas outlet, and the liquid flows out from the liquid outlet.

[0003] The existing natural gas vertical separators are of relatively traditional design, with simple internal structures and average gas-liquid separation effects.

[0004] After searching, a Chinese patent with publication number CN216864099U discloses a natural gas vertical separator. The utility model performs gas-liquid separation through a separation cylinder, then filters the natural gas through a corrugated plate filler, and finally removes foam in the natural gas with a foam catcher. The natural gas after gas-liquid separation is discharged from the gas outlet pipe of the upper head. The gas-liquid separation can be achieved by using the corrugated plate filler, the foam catcher, and the separation cylinder in combination.

[0005] However, when the above vertical separator is actually used, during the separation of natural gas in an enterprise, grease liquid will accumulate at the bottom of the separator. It takes a long time to discharge the grease liquid, which may cause excessive accumulation of grease and affect the efficiency of natural gas gas-liquid separation. Utility Model Content
