The filter paper 18 can be medical filter cotton paper.

[0028] The filter cylinder 14 is made of stainless steel, and the surface of the filter cylinder 14 is coated with a corrosion-resistant coating. The stainless steel has excellent mechanical strength and can withstand mechanical vibration, pressure fluctuation and external impact during the operation of the device, so that the filter cylinder 14 can maintain stable shape under complex working conditions, avoid the decrease of filtering precision or sealing failure caused by deformation, and the corrosion-resistant coating (such as polytetrafluoroethylene PTFE or epoxy resin) can fill the micro pores on the surface of the stainless steel to form a dense protective layer, so as to isolate the penetration of corrosion media such as water in oil and chloride ions, and further reduce the risk of local corrosion.

[0029] The device further comprises a circular groove 4 and a sealing ring 5, the circular groove 4 is arranged on the base 1 and the top seat 2 respectively, and the gas collecting cup 6 is arranged in the circular groove 4 of the base 1 and the top seat 2 through the sealing ring 5 respectively.

[0030] In the embodiment, the circular groove 4 is arranged on the base 1 and the top seat 2 respectively to accommodate the gas collecting cup 6; meanwhile, in order to further improve the sealing effect, the sealing ring 5 is arranged to seal the gap between the sealing ring 5 and the circular groove 4. The sealing ring 5 forms a surface contact with the gas collecting cup 6 through compression deformation, so that the sealing effect is more reliable, and the device is especially suitable for high pressure difference or high vacuum working conditions.

[0031] The outlet 7 and the gas collecting cup 6 have two communication modes, one is that the outer wall surface of the gas collecting cup 6 is in contact with the outer wall surface of the circular groove 4, and there is a certain gap between the inner wall surfaces of the two, and the outlet 7 penetrates through the gas collecting cup 6 and the circular groove 4; the other is that one end of the outlet 7 is communicated to the overlapping area of the base 1 and the gas collecting cup 7.

[0034] In the embodiment, a chromatographic analyzer, a gas generating device and a gas pushing device are further included; the chromatographic analyzer is used for analyzing the gas separated from the oil and gas; the gas generating device is communicated with the feed inlet 19, and the gas pushing device is communicated with the gas outlet 7 and the chromatographic analyzer respectively; the gas generating device and the gas pushing device both comprise a cylinder, specifically a pneumatic cylinder, which is driven by carrier gas to move the piston, so as to push the gas to the chromatographic analyzer, or the piston creates a vacuum environment in the cylinder.

[0035] The working process of the application is as follows: A certain amount (20ml) of oil sample is pushed into the gas generating device, the gas generating device creates a vacuum in the cylinder under the action of carrier gas, so that the inside of the cylinder is a vacuum environment. Due to the extremely low pressure in the vacuum environment, the oil sample will vaporize instantly after entering. In the vaporization process, the fault gas dissolved in the oil sample will escape from the liquid oil due to its low boiling point, thereby realizing effective separation of the gas and the liquid oil. The separated gas enters the feed inlet 19 through the pipeline under the action of pressure balance. The gas enters the filter cartridge 14 from the feed inlet 19. When the gas containing liquid oil molecules passes through the filter cartridge 14, 70% of the oil molecule impurities in the gas can be effectively intercepted by the filter paper, so that the gas is preliminarily purified. This purification process greatly reduces the content of liquid oil molecules entering the chromatographic column during subsequent chromatographic analysis, thereby reducing the pollution risk of the chromatographic column from the source. The filtered and purified gas enters the gas pushing device from the outlet 7, and the piston in the gas pushing device pushes the gas under the action of carrier gas, so that the gas enters the chromatographic analyzer for chromatographic analysis.

[0036] The fixing unit comprises a fixing part and a locking part, the fixing part is installed on the filter unit, the locking part is installed on the top seat 2, and the fixing part and the locking part are movably connected.
