Abstract

According to the mobile monitoring device and method for the sulfur content of the marine fuel oil, the device and method are easy to operate, the sulfur content of the marine fuel oil can be estimated only by using the SO2 gas concentration monitored by the multi-source sensor mobile carrying platform and the established ship atmospheric pollutant emission diffusion model, the influence of CO2 monitoring concentration information on the precision of the estimation value of the sulfur content of the marine fuel oil is greatly reduced, and the credibility of the estimation result of the sulfur content of the marine fuel oil is improved; meanwhile, the investment cost of monitoring equipment is saved to a great extent, the operating skill requirements of technicians are reduced, the operability is high, the method for estimating the sulfur content of the marine fuel oil is high in automation degree and easy to implement, and an intelligent and efficient device and method are provided for maritime affair supervision departments to recognize illegal high-sulfur oil ships.

Description

technical field [0001] The invention belongs to the field of ships, and in particular relates to a mobile monitoring device and method for the sulfur content of marine fuel oil. Background technique [0002] The ship emission control policy stipulates that fuel oil with a sulfur content not exceeding 0.5% m / m should be used when entering the domestic emission control area. Therefore, it is necessary to monitor the sulfur content of marine fuel oil to ensure the implementation of ship emission control policies. At present, the existing results are based on SO 2 and CO 2 Calculate the sulfur content of marine fuel oil based on the ratio of the monitored concentration. [0003] The patent with the publication number CN109901615A discloses a ship emission detection method and system based on a flying platform. The gas monitoring sensor carried by the drone is used to collect the exhaust gas concentration of the ship, and the emission factor of the plume center is calculated t...
