Sea surface spilled oil rapid separation and recovery device

Abstract

The invention relates to a sea surface spilled oil rapid separation and recovery device which comprises a support frame, a vortex-making recovery tank, vortex-making blades, a motor, a submersible pump and a primary vortex separator. Float bowls are connected to the head and tail ends of the lower part of the support frame. The vortex-making recovery tank is fixed on the support frame, and the vortex-making blades are positioned in the vortex-making recovery tank. The motor is vertically fixed to the middle position over the vortex-making recovery tank through the support frame. The motor is connected with the vortex-making blades located under the motor. A hole is formed in the center of the bottom of the vortex-making recovery tank, and the submersible pump vertically penetrates throughthe hole and is fixed to the hole. A liquid inlet of the submersible pump is located at the height of an oil layer formed after liquid in the vortex-making recovery tank forms Rankine combined vortexes, and a liquid outlet of the submersible pump is connected with the primary vortex separator through a primary mixed liquid pipeline. The device is small in size, low in weight and convenient to transport and install, and can be quickly hauled to an oil leakage site. Compared with a traditional direct extraction method, mixed liquid with higher oil phase content can be conveyed into the separation device, and the separation efficiency is further improved.

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 device. 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...
