| With the development of the country in recent years,the level of human life is gradually increasing.At the same time,the consumption of oil energy is also increasing.But the oil spilling occurs in transportation,which bring terrible trouble to the human life.Currently,the situation of prevention and disposal of marine oil spill accidents,even protecting the ecological environment of the Earth and the oceans is still grim.Oil spill identification is a very important part in dealing with marine oil spills.It is great significant to reduce the risk of accidents,and to reduce processing costs and time.if you can fastly and accurately complete this work.Therefore,if there is a way to quickly identify the oil spill,it can improve the efficiency of the accident processing efficiency.Based on the simulation of shipborne oil spill,a fast identification method of crude oil and lubricating oil mathematical has been proposed.This paper first introduces the background and purpose of the research,and makes a brief investigation on the oil spill identification method and the marine oil spill monitoring system both at home and abroad.And the main work of this paper was summarized.On the other hand,the basic principles of laser induced fluorescence spectroscopy were introduced in detail,including the generation of fluorescence,the basic parameters,and the influence conditions.The work of this paper mainly includes the following aspects: First,On the basis of the relevant information,the existing methods of oil identification were compared and reviewed;Secondly,the laser induced fluorescence spectroscopy method was analyzed,and the feasibility of this experiment was analyzed;Thirdly,for the oil spill samples,an experiment was carried out to simulate the identification of shipborne marine oil spills.The experimental optical path was designed.According to the experimental requirements,the experimental apparatus was selected and the samples were prepared.The spectral information of oil source samples was detected in the direction of backscattering.The spectral characteristics of crude oil and lubricating oil were analyzed according to this spectral information.Simultaneously,the characteristic information of both were identified.Fourth,a method for the fast identification of crude oil and lubricating oil was proposed and its feasibility was verified.We propose to use the ratio of the main laser scattering intensity and the peak intensity as the characteristic value,this can intensify the difference between the two oils.The results that the identification probability of the two oils showed is as high as 95%. |
