Ship fuel oil sulfur content ratio remote sensing monitoring system and method

Abstract

The invention provides a ship fuel oil sulfur content ratio remote sensing monitoring system and method. According to theship fuel oil sulfur content ratio remote sensing monitoring system, a remote sensing detection device obtains content parameters of sulfur dioxide in an open environment through an absorption spectrum technology, and obtains a content parameter of carbon dioxide in an open environment by applying an absorption spectrum technology; detection light paths of sulfur dioxide and carbon dioxide are coaxial, and the detection light paths cross a navigation channel of the ship; and a calculation module is used for obtaining the sulfur content ratio of the ship fuel oil. The system has the advantages of good accuracy and the like.

Description

technical field [0001] The invention relates to fuel oil monitoring, in particular to a remote sensing monitoring system and method for the sulfur content ratio of ship fuel oil. Background technique [0002] In November 2018, the Ministry of Transport issued the "Notice of the Ministry of Transport on Printing and Distributing the Implementation Plan for Ship Air Pollutant Emission Control Areas". Basically, the emission control area will be extended to inland rivers, including the navigable waters of inland rivers in cities above the prefecture level along the river and the navigable waters of the main line of the Yangtze River. It is required that ships entering the coastal control area from January 1, 2019 should use marine fuel oil with a sulfur content not greater than 0.5% m / m. From January 1, 2020, sea-going ships entering the inland river control area shall use marine fuel oil with a sulfur content not greater than 0.1% m / m [0003] Due to the large price differen...

Problems solved by technology

The UAV sniffer method adopts the onboard electrochemical sensor module of the UAV, and the UAV is manually operated to follow the trajectory of the ship to measure the SO emissions of the ship's exhaust. 2 , CO 2 , NO 2 and other gases, so as to convert the fuel sulfur ratio, this method requires skilled drone operators and a good measurement environment in actual operation, the cost is high, the use conditions are limited, and the operability is poor; the shore-based sniffing method is passed Install a traditional air quality automatic monitoring system on the shore where the ship passes to measure the SO in the air when the ship passes by. 2 , CO 2 , NO 2 Etc. the change of exhaust gas, so as to convert the fuel sulfur ratio. This method is simple to install, but the measurement is affected by factors such as wind speed, wind direction, and other mobile source emissions in the environment. Especially in the monitoring of inland river control areas, there are often missed measurements, even unresponsive
