The container body 1 has an inner cylinder structure 4, and the filter cylinder 2 is disposed inside the inner cylinder structure 4. The outer side of the container body 1 has a liquid inlet 11 and a liquid outlet 12, which are connected to each other through the inner cylinder structure 4 and the filter cylinder 2. This allows the extracted crude oil to enter the container body 1 through the liquid inlet 11, and its flow direction will be changed under the action of the inner cylinder structure 4 and the filter cylinder 2. After gas-liquid separation and filtration, the crude oil liquid will be output through the liquid outlet 12. The top of the container body 1 has an exhaust port 13, and the container body 1 has a support structure 5 above the filter cylinder 2. The lower end of the float assembly 3 is movably connected to the support structure 5. During operation, the float assembly 3 can move up and down relative to the support structure 5. The upper end of the float assembly 3 has a plug 31 for sealing the exhaust port 13.

[0037] In some embodiments of the utility model, the lower portion of exhaust port 13 is formed with a tapered guide port 14, and the plug 31 is a tapered structure matching the tapered guide port 14, so that the plug 31 can cooperate with the tapered guide port 14 to block the exhaust port 13. The diameter of the exhaust port 13 is 10-25 mm. When the improved degasser 100 works, as the separated gas accumulates at the top of the container body 1, when the pressure in the container body 1 reaches a certain value, the crude oil liquid level in the container body 1 will drop under the action of the gas pressure, and the drop of the crude oil liquid level will make the float ball subassembly 3 drive the plug 31 to drop and open the exhaust port 13, so that the gas at the top of the container body 1 can be quickly discharged through the exhaust port 13. As the gas in the container body 1 is discharged, the crude oil liquid level in the container body 1 will rise again, and the rise of the crude oil liquid level will make the float ball subassembly 3 drive the plug 31 to rise and block the exhaust port 13. This cycle realizes gas-liquid separation.
