The overflowed mineral oil can be separated from water again through the discharge pipe 17.

[0024] Furthermore, a flow control valve 18 is installed on the surface of the connecting pipe 4, and the flow control valve 18 is used to control the flow rate of the mineral oil discharged from the connecting pipe 4 into the separation box 5 to avoid overflow of the mineral oil due to excessive flow rate, and the flow rate of the mineral oil inside the connecting pipe 4 is equal to the extraction flow of the extraction pump 15 plus the filtration speed of the hydrophilic and oleophobic filter layer 7.
