[0025] Please refer to Figures 1 to 3 , the present utility model provides an oil-gas separation tank, which includes a tank body 1. An oil-gas inlet 11 and an exhaust port 12 are arranged on the tank body 1. A cyclone guide member 2 and an oil separation core assembly are arranged inside the tank body 1, and the oil separation core assembly and the cyclone guide member 2 are arranged up and down; a guide hole is opened in the middle of the cyclone guide member 2, a guide channel is arranged on the outside of the cyclone guide member 2, the side part of the guide channel is communicated with the oil-gas inlet 11, and the bottom of the guide channel and the guide hole are used for conveying oil-gas to the oil separation core assembly. The exhaust port 12 is arranged on one side of the oil separation core assembly, and the exhaust port 12 is used for outputting the gas separated by the oil separation core assembly.

[0026] This application discloses an oil-gas separation tank. A cyclone guide member 2 is arranged inside the tank body 1, so that the oil-gas mixture entering the oil-gas separation tank forms a swirling flow, thereby enhancing the centrifugal force between oil droplets and gas, helping the oil droplets to separate from the air flow, achieving the effect of primary separation, and improving the overall oil-gas separation effect and separation efficiency of the oil-gas separation tank; and the oil droplets are partially separated before reaching the oil separation core assembly, reducing the oil content in the oil-gas mixture that the oil separation core assembly needs to process, reducing the load of the oil separation core assembly, extending the service life of the oil separation core assembly, and indirectly reducing the maintenance cost of the oil-gas separation tank.

[0027] During the actual working process, the oil-gas to be separated enters the guide channel through the oil-gas inlet 11 for primary separation, then enters the inside of the tank body 1 through the bottom of the guide channel, and then enters the input end of the oil separation core assembly through the guide hole. The oil separation core assembly further separates the oil-gas, and the separated gas is discharged from the oil-gas separation tank through the exhaust port 12.

Since the upper plate 21 and the lower plate 23 are respectively inclined upward and downward, the flow of gas and solid particles can be effectively guided. When the oil-gas mixture enters the cyclone guide member 2, this inclined design enables the oil droplets to settle more easily to the bottom of the cyclone separator due to gravity, while the gas continues to flow upward through the guide holes, thereby achieving effective solid-gas separation. Moreover, the upward inclination design of the upper plate 21 helps prevent particles from accumulating and blocking on the guide plate, reducing the maintenance frequency of the upper plate 21.
