Restricted by existing oil transportation technology,marine oil spills occur frequently.This phenomenon seriously reduces the quality of the marine environment and affects the development of the marine economy.Therefore,there is a great need for an efficient marine oil recovery technology.However,the traditional methods of recovering oil from the ocean have many disadvantages: low recovery efficiency,high recovery cost,and causing second pollution.In recent years,the usage of special wettability surface for achieving oil-water separation has became a hot spot.The point is that applying this method can effectively avoid many problems arising from oil-water separation based on traditional methods.In this paper,I will develop a prototype of a marine oil slick recovery device with super-amphiphobic mesh,which possesses simple and reliable structure and enable to detect the working status,and verify its working reliability through experiments at last.Firstly,the background of ocean slick oil recovery is briefly overviewed and the characteristics,preparation methods of the super-amphiphobic mesh are then respectively discussed in the text.This paper also introduces the working principle of the mesh that how to achieve oli-water separation.A significant process-finding the parameters affecting the separation efficiency of this super-amphiphobic mesh-are also analyzed.Based on the working above,it could not be difficult to ascertain the technical indicators and the overall design of this recovery device.Next,super-amphiphobic mesh's separation flow would be efficiently calculated according to the Bernoulli equation.Then,given the designed technical indicators and the above theory,the overall size of the device and the design principle could be further confirmed,other key structures of the device would also be designed accordingly.Secondly,a hardware system is going to be designed,under data measurement requirements and control requirements proposed in the overall design plan,using the single chip microcomputer as the main control chip,and cooperating with other peripheral circuits to build the control system,which has a goal of data collection and display,weir edge angle adjustment,oil slick recovery device start and stop control,etc.Besides,the appropriate materials,pipelines,oil pumps,sensors,motors,power supplies,etc.are also employed to complete the construction of the structure part and hardware part of the device.The last butsignificant,the design of the software system has the aim to support the hardware system to realize the corresponding functions.And the program is written in the structure of the underlying hardware layer,the intermediate driver layer and the application layer.After constructing marine oil slick recovery device,the next action is to conduct experiments in order to verify the mechanical structure,hardware system functions,and determine the feasibility of the overall design plan.Use the device that is more operational and easier to obtain experimental data to conduct the oil-water separation experiment of the super-amphiphobic mesh.The experiment includes the effect of the number of super-amphiphobic base mesh,the oil content in the mixture and its temperature on separation efficiency.With the results,a suitable mesh was selected and installed in the marine oil slick recovery device.The next step is to explore the impact of the working hours of the oil slick recovery device and the long-term use in different marine environments on the recycle effect of the recovery device.Based on the experimental results,we can analyze whether the recovery efficiency,corrosion resistance,durability and separation flow rate of the marine oil slick recovery device designed in this paper meet the design requirements.The conclusion is that the device meets the design requirements,and the marine slick oil recovery device designed in this paper can provide reference suggestions for the development of the actual device.
