Description

Technical Field

[0001] The utility model relates to the technical field of oxygen production, in particular to a gas-liquid separation device for oxygen production. Background Art

[0002] When oxygen is produced, the air needs to be filtered and pressurized under low temperature conditions to convert it into liquid air. The liquid air is then separated using a gas-liquid separation cylinder. Since the boiling point of liquid nitrogen is lower than that of liquid oxygen, the nitrogen evaporates from the liquid air first, and the rest is liquid oxygen, which is discharged.

[0003] However, the current gas-liquid separation cylinder usually uses a cylinder, a cyclone gas-liquid separation cylinder and a high-efficiency foam breaking net for separation in the process of separating liquid air. The effect of separating liquid air is poor, and it is difficult to quickly separate and discharge nitrogen and oxygen in the liquid air, which reduces the separation effect during oxygen production. To this end, we propose a gas-liquid separation device for oxygen production to solve the above problems. Utility Model Content
