Embodiment

[0038] This embodiment provides a rapid separation and recovery system for oil spilled on the sea surface, which is composed of an oil spill recovery module installed on a buoy and a recovery object separation module installed on an engineering ship, and the oil spill recovery module and the recovery object separation module are connected through pipelines ;

[0039] The oil spill recovery module includes a submersible pump 3, a vortex separator-2, a signal control device 4, and a traction system 5; the submersible pump 3 is connected to the vortex separator-2 through a pipeline and placed side by side on the side of the buoy . The flow rate of submersible pump 3 is 300m 3 / h, which can meet the needs of large processing capacity; the vortex separator-2 is provided with three and arranged in parallel, which can adjust the processing capacity of the incoming liquid, increase the centrifugal force, and better separate the oil-water mixture. The three vortex separators Separato...

Abstract

The invention relates to a sea surface spilled oil rapid separation and recovery system. The rapid separation and recovery system comprises a spilled oil recovery module and a recovered material separation module. 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.

Description

technical field [0001] The invention belongs to the technical field of sea surface oil spill recovery, in particular to a sea surface oil spill rapid separation and recovery system. Background technique [0002] In the context of the recovery and continuous growth of the world economy, the development of the world's oil industry has ushered in new opportunities. my country has vast sea areas, and there are rich oil resources in Bohai Bay, South China Sea and other sea areas that have yet to be exploited. However, in the process of crude oil extraction and gathering and transportation, crude oil leakage may occur. In view of the density difference between crude oil and seawater and the incompatibility between the two, the leaked crude oil will float in the sea area near the leak site in a free state, causing extremely bad effects on the ecosystem around the sea area and threatening the safety of workers' lives and property. The crude oil leaked at the same time is also a gre...
