Abstract

The invention discloses an online analysis system of a ship exhaust emission. The online analysis system of the ship exhaust emission comprises a flue gas sampling unit, a flue gas pretreatment device, a flue gas analysis system, a flue gas parameter measuring system, an automatic blowback control system, a data acquisition system (DAS), a smoke monitoring system, a flue, a gas testing room and an analysis instrument cabinet, wherein the flue gas sampling unit comprises a sampling probe, a smokometer, a flowmeter, a moisture tester, a pressure sensor and a temperature sensor; the flue gas pretreatment device comprises a sample gas pretreatment unit, calibration equipment and a purging unit; the flue gas sampling unit is arranged in the flue, and connected with the analysis instrument cabinet through a cable; the flue gas pretreatment device and the flue gas analysis system are both mounted in the analysis instrument cabinet. With the adoption of the online analysis system of the ship exhaust emission disclosed by the invention, real-time, on-line and continuous detection of a variety of pollutants in flue gases can be carried out, a gas chamber can be prevented from corrosion damage and pollution, and a gas pipeline can be prevented from blockage; furthermore, the performances are stable and reliable, and the maintenance workload is small.

Description

【Technical field】 [0001] The invention relates to the technical field of smog gas detection and analysis, in particular to the technical field of an online analysis system for ship exhaust gas discharge. 【Background technique】 [0002] At present, ocean-going ships in Chinese ports mainly use heavy oil as fuel, with a sulfur content of 2.8% to 3.5%, and some as high as 4.5%. In addition, the lack of strict engine emission standards has led to increasingly prominent impacts on ship pollution emissions. According to the National Environmental Protection Ministry's Emission Monitoring Center, in 2013, ships berthing at Chinese ports emitted a total of 588,000 tons of SO2, accounting for about 8.4% of the country's total emissions; port ships discharged 278,000 tons of nitrogen oxides, accounting for about 100,000 tons of emissions in China. 11.3% of the total. The diesel particulate matter, nitrogen oxides, and sulfur oxides contained in the smoke emitted by the 180,000 ships ...
