Technical Field

The invention relates to the field of simulation devices, in particular to a marine oil spill repair simulation device based on a magnetic nano composite oil absorption material.

Background

In recent years, foreign oil-absorbing materials have been developed in the direction of using synthetic polymer compounds, and although oil stains can be adsorbed, collection of such materials after adsorption has become a troublesome problem. In addition, some toxic oil-phase waste liquids with special uses are not accessible at all for their toxicity reasons, let alone for efficient collection or recovery treatment, and so an adsorbent material that can be moved directionally and easily recovered is particularly important in the adsorptive treatment of oily waste waters and water surface spills. Therefore, a novel environment-friendly oil absorption material is developed, the material can keep the advantages of oil spill treatment by an adsorption method, can avoid bringing new environmental problems, can realize directional recovery of the oil spill, is an urgent need for solving marine oil pollution, and has a wide application prospect.

However, in the practical application process, there are both lack of experience in use, and there are also lack of research and experiments on what kind of magnetic nano composite oil absorption material is adopted to deal with different sea conditions in sea areas and different oil types, so a simulation device which can simulate sea condition environment well and can be applied to the magnetic nano composite oil absorption material to simulate marine oil absorption needs to be specially formulated. The existing sea condition simulation device which is not targeted can only simply adopt a pump or a stirring centrifugal mode to simply simulate, but the simulation effect is extremely poor.
