AI Technical Summary
Existing marine oil spill control and seawater desalination equipment suffers from significant drawbacks, such as high energy dependence, high mechanical resistance leading to jamming, and easy scaling during long-term operation, making it difficult to operate effectively in remote sea areas without conventional energy coverage.
The device employs a self-driven double-cone rotary drum integrated photothermal oil-water purification and desalination system. It utilizes the mass difference generated by the asymmetric photothermal phase change to drive the drum rotation. Combined with the radial gradient aperture structure and photothermal effect, it achieves non-contact oil collection and salt dissolution, avoiding mechanical friction and salt crystallization and scaling.
It has achieved autonomous operation in scenarios without conventional energy coverage, solved the problems of mechanical resistance and salt crystallization, ensured stable operation of the equipment and efficient oil collection and desalination, and improved the starting torque and photothermal conversion efficiency.
