AI Technical Summary

Technical Problem

Existing oil spill recovery equipment is inefficient in recovering heavy oil and emulsified oil, and suffers from problems such as difficult relocation, cumbersome setup, and insufficient adaptability, especially in recovering thick and thin oil layers.

Method used

The marine oil spill recovery device combines a disc-type oil collection device and a vacuum oil collection device. It uses a rotating disc assembly to absorb heavy oil and scrape it into the oil guide pipe. It uses a vacuum pump and an oleophilic filter to accelerate oil-water separation. It combines an automatic sealing and packaging module to achieve continuous collection and sealing of oil spills. It uses a water jet propulsion device to reduce energy consumption.

Benefits of technology

It achieves efficient recovery of both thick and thin oil layers, improves oil recovery performance and separation efficiency, reduces the volume and transportation difficulty of the equipment, and does not cause secondary pollution during the recovery process.
