Device and method for classifying and detecting seawater spilled oil by using spectral analysis technology

Abstract

The invention discloses a device and a method for carrying out classified detection on seawater spilled oil by utilizing a spectral analysis technology, belonging to the technical field of multispectral measurement. A fluorescence spectrum is adopted to identify gasoline and diesel oil, and a Raman spectrum is adopted to identify crude oil, fuel oil and light oil; smooth denoising, baseline correction and peak value pickup are performed on the fluorescence spectrum and the Raman spectrum, so that accurate pickup of the position and intensity of the characteristic peak is realized, the problem that oil product identification is easy to generate errors due to inaccurate estimation of the position of the characteristic peak is solved, and the accuracy of seawater spilled oil classification is improved. Meanwhile, an automatic circulation platform, an optical detection system and an automatic control unit are designed in the seawater oil spill classification detection device, and the whole process from seawater sampling, mixing, oil spill excitation, optical signal acquisition, spectrum processing to oil spill classification identification can be automatically completed, so that the speed and accuracy of oil spill classification detection are improved, and the detection efficiency is improved. In addition, in-situ detection of seawater can be achieved, and the problem that oil spilling is difficult to trace is solved.

Description

technical field [0001] The invention belongs to the technical field of multi-spectral measurement, and in particular relates to a device and a method for classifying and detecting seawater oil spills by using spectral analysis technology. Background technique [0002] With the rise of offshore oil exploration and exploitation, offshore oil spills and oil spill accidents from tankers have occurred frequently, causing a large amount of oil and various types of oil products to flow into the ocean, causing serious pollution to the marine environment. Since the supervision of the exploitation of crude oil and refined oil often belongs to different law enforcement departments, when oil pollutants appear in seawater, it is first necessary to determine the type of oil spill, and then determine the relevant law enforcement department to supervise, manage and trace the source according to the type of oil spill. Therefore, it is necessary for some law enforcement agencies to classify a...

Problems solved by technology

[0003] At this stage, for the detection and classification of petroleum and its various oil products, the most common methods are liquid chromatography and gas chromatography. These methods need to sample the oil spilled in seawater and send it to the laboratory for testing The large-scale equipment in the laboratory completes the classification and detection of oil products, which not only takes a long time and is costly, but also has poor timeliness, which makes it difficult to trace later
