Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas recovery and separation, in particular to an oil and gas recovery and separation membrane core component. Background Art

[0002] During the recovery and reuse of oil and gas, air will be mixed in the oil and gas, which will affect the reuse of the oil and gas. A separation membrane gas separation device is needed to separate the oil and gas from the air. The separation membrane core assembly is an important component of the separation membrane gas separation device and directly affects the gas separation effect.

[0003] When the existing membrane core assembly is in use, it is only convenient to separate oil and gas from the air. When the filtered air is discharged, a small amount of oil and gas will be discharged at the same time. It is not convenient to discharge the small amount of oil and gas mixed inside through the separation membrane during the air discharge process. The oil and gas separation effect is poor, resulting in the waste of this part of the oil and gas discharge. Utility Model Content
