Description
Technical field
The invention belongs to Air Pollution Control field, is related to a kind of waste gas and discharges online Monitoring and control system, specifically relates to
A kind of and ship tail gas on-line monitoring and control system.
Background technology
Calculated according to Surveillance center of State Ministry of Environmental Protection, the discharge capacity of the ship sulfur dioxide of Chinese Port in 2013 accounts for entirely
The 8.4% of state's total emission volumn, nitrogen oxides account for the 11.3% of national total emission volumn, and yard craft tail gas pollution turns into after machine
The third-largest source of atmospheric pollution after motor-car tail gas pollution, industrial enterprise's gaseous contamination, the improvement to Pollution From Ships are very urgent.
According to statistics, for more than 90% ship using diesel engine as power source, ship discharge exhaust emission is mainly sulphur
Oxide, nitrogen oxides (NOx), oxycarbide (COx), hydrocarbon (HC) etc., if ship discharges waste gas without improvement
Directly very important harm will be caused by draining into air.After nitrogen oxides (NOx) suction human body, with steam combination shape in lung
Into dust technology, severe damaging body health；Under solar radiation, nitrogen oxides (NOx) can also generate with hydrocarbon (HC)
Chemical fumes, make one headache, tetany.Hydrocarbon (HC) has to the respiratory system of people, nervous system, hemopoietic system
Serious damage effect.In addition, hydrocarbon (HC) influences agriculture, woods, fishing, animal husbandry as formed acid rain meeting polluted lake soil
Deng production.
The problem of being directed to marine exhaust discharge,《MARPOL in 1973》Supplemental provisions 6- prevents ship
Oceangoing ship causes clear stipulaties in air pollution rule to discharge the oxysulfide (SO in waste gas to shipX) and nitrogen oxides (NOx) enter
Row content limits and forbids damaging the intentional discharge of ozone material.《Engine of boat and ship tailpipe emission limit value and measurement side
Method (Chinese first and second stage)》(GB15097-2016) nitrogen oxides (NOx), oxycarbide (COx), hydrocarbonization be it is also proposed
The discharge limitation of the pollutants such as compound (HC) and its measuring method.Therefore, the processing to marine exhaust and detection turn into waste gas and arranged
Most important step before putting, because on-line monitoring analysis system has the advantages of monitoring in real time, gradually it is applied to ship
