The spilled oil recovery module comprises a submersible pump, a vortex separator I, a signal control device and a traction system. The recovered material separation module comprises a centrifugal pump, a vortex separator II, an eccentric T-shaped sleeve, a column type cyclone, a buffering bifurcated pipe, a control cabinet, an operation table and a flow and parameter acquisition display table. The submersible pump is connected with the vortex separator I. An oil outlet of the vortex separator I is sequentially connected with the centrifugal pump and the vortex separator II. A water outlet of the vortex separator II is connected with the eccentric T-shaped sleeve. A water outlet of the eccentric T-shaped sleeve is connected with the column type cyclone. A water outlet of the column type cyclone is connected with the buffering bifurcated pipe. An oil outlet of the vortex separator II, an oil outlet of the eccentric T-shaped sleeve, an oil outlet of the column type cyclone and an oil outlet of the buffering bifurcated pipe are all connected with an oil storage bin. The floating oil recovery and separation efficiency can be greatly improved, and the crude oil separation pressure of system equipment is reduced.
