Embodiment

[0031] The fixed sniffer is deployed on the shore and on the bridge under the prevailing wind in the main channel where ships come and go, away from other sources of interference emissions. The best distance from the exhaust port of the ship is about several hundred meters, the intake pipeline is integrated, and the total flow rate of sampling is about 12L / min.

[0032] Such as figure 1 The shown sniffer system is built in a waterproof box, in which the NOx analyzer adopts Thermo42i-TL, and the response time (t 90 ) is 1s, the precision is 1ppb; SO 2 Analyzer adopts Thermo 43i-TLE (no kicker), t 90 =2s, accuracy 5ppb; CO 2 The analyzer adopts LI-COR 7200,t 90 =0.1s, precision 0.3ppm.

[0033] NO x Analyzer, SO 2 Analyzer, CO 2 The data obtained by the continuous measurement of the analyzer is used to generate a time-concentration diagram by the measurement computer and calculate the FSC for each peak.

[0034] The direction of the smoke plume is judged by the wind spe...

Abstract

The invention discloses a sniper applied to the identification of polluting ships. The sniper comprises an acquisition module, a measurement and calculation module, a ship monitoring module, a ship identification module, and a 5G wireless transmission module; the acquisition module is used for acquiring the concentration information of pollutants discharged by passing ships; the measurement and calculation module is used for receiving the concentration information of the pollutants acquired by the acquisition module and calculating the sulfur content information of a fuel; the ship monitoringmodule is used for monitoring the positions, navigational speeds, courses and information of the plurality of ships; the ship identification module is used for receiving the sulfur content data of thefuel transmitted by the measurement and calculation module and ship states transmitted by the ship monitoring module; the 5G wireless transmission module is used for receiving the information of ships which discharge pollutants exceeding standards and the sulfur content numerical value of the fuel, wherein the information of the ships and the sulfur content numerical value are transmitted by theship identification module; and the 5G wireless transmission module transmits the received data information to a monitoring center in real time.

Description

technical field [0001] The invention relates to the technical field of identifying polluted ships, in particular to a sniffer used to identify polluted ships. Background technique [0002] The pollution problem caused by ship transportation is becoming more and more serious. A large part of the annual global sulfur dioxide and nitrogen oxide emissions comes from ships. Ship pollution has become the main source of air quality pollution in many port cities and inland river areas. In December 2015, the Ministry of Transport issued the "Implementation Plan for Ship Emission Control Areas in the Pearl River Delta, Yangtze River Delta, and Bohai Rim (Beijing-Tianjin-Hebei) Waters" to control pollutant emissions by establishing ship air pollutant emission control areas. It is stipulated that from January 1, 2019, all ships sailing in the emission control area must use fuel with a sulfur content of less than 0.5%. The policy promises significant air quality and health benefits, but...
