[0031] In the oil-gas separation device 100 provided by the utility model, the oil-gas mixture is transported from the air inlet channel 1b to the inner cavity 1a of the water tank 1. Since the air inlet channel 1b is located in the solution (water) contained in the inner cavity 1a, the oil-gas mixture output from the air inlet channel 1b can first be deprived of the oily components in the oil-gas mixture through the water, and the gas floats from the water to the outside of the water surface; and is transported to the side of the partition 2 away from the air inlet channel 1b through the connecting pipe 3, and then the gas after the oily components are removed is discharged through the air outlet 1c for subsequent process processing. In this scheme, since the partition 2 can isolate the initially removed oily components on the side close to the air inlet channel 1b, it is prevented that the gas output from the air outlet end 32 of the connecting pipe 3 is mixed with the oily components again when passing through the solution, the purity of the separated gas is improved, and then the oil-gas separation efficiency is improved, and the structure is simple and the cost is relatively low. At the same time, after a period of use, only water needs to be replaced to ensure a certain separation efficiency, and there is no need to frequently clean the parts, and the operation is relatively simple.

[0034] For further information, see Figure 2 The oil-gas separation device 100 further includes a fixing plate 4 and a limiting portion. The fixing plate 4 is movably mounted on the side wall of the inner cavity 1a in the vertical direction. The limiting portion is disposed between the fixing plate 4 and the side wall of the inner cavity 1a to limit the movement of the fixing plate 4 when the height of the fixing plate 4 is adjusted to a preset position. The connecting pipe 3 is mounted on the fixing plate 4. In this embodiment, the height of the air inlet end 31 of the connecting pipe 3 can be adjusted by moving the fixing plate 4 in the vertical direction, thereby flexibly adjusting the height of the water surface, thereby improving practicality.

[0035] Specifically, the side wall of the inner cavity 1a is provided with an adsorption member 15, and the adsorption member 15 is extended in the vertical direction corresponding to the fixed plate 4.

The adsorbing member 15 is located on the inner wall of the limiting groove 1a1, and the end of the magnetic adsorbing member 41 of the fixing plate 4 extends into the limiting groove 1a1.
