The invention discloses a quick-
insertion type emergency oil-water separation device based on double metamaterials, and relates to the technical field of
environmental protection. According to the scheme, oil liquid can be filtered and stored in an
oil storage tank through a filter membrane, and along with the increase of the oil liquid in the
oil storage tank, an oil floater drives a vertical sliding
barrel to move upwards along with large
buoyancy provided by the oil liquid; when the vertical sliding
barrel moves upwards, based on the fact that the
buoyancy adjusting tank is in an immersed state, the oil floater provides large
buoyancy with oil as a carrier, the buoyancy counteracts the
water pressure of the buoyancy adjusting
piston and slides upwards on the inner wall of the buoyancy adjusting tank, and water in the buoyancy adjusting tank is discharged through a water passing hole. External air penetrates through the vertical sliding
barrel through
suction force to enter the buoyancy adjusting tank, so that buoyancy of the buoyancy adjusting tank is increased, the weight of oil stored in the buoyancy adjusting tank is counteracted, and by means of the mode, the self-weight is continuously increased along with increase of the oil; the buoyancy is automatically controlled according to the amount of the oil liquid, so that the immersion depth of the filter membrane in the continuous oil liquid
separation process is always in the optimal state.
