The increase of fossil fuel such as coal and oil consumption not only causes atmosphere pollution (NO
x, SO
x) and the generation of acid rain, and produced a large amount of greenhouse gases (CO
2).CO
2Can absorb the solar infrared beta radiation, the earth atmosphere circle is heated, cause the improper differentiation of global environment, and the life threatening system exists and development.Greenhouse gases are by CO
2, CH
4, CFC
x, NO
2Deng gas composition, its main component is CO
2For exploring the influence of greenhouse gases to the global climate environmental change, people have carried out the evaluation activity of multidisciplinary property, and its result of study shows that the trend of global warming is mainly caused by greenhouse effects.Because influence factor is more, greenhouse gases burst size and the difficult foundation of its comprehensive definite model to the relation of global environment influence.Though, CO
2Nontoxic and human body do not had remarkable damaging effect, but it is at the shared ratio height of greenhouse effects, big to the Global climate change influence, caused people's common concern.After coming into force to Kyodo Protocol, be the country of main energy sources structure with the fossil fuel, international environment pressure increases day by day, and these have promoted the development to greenhouse gases control technology and equipment.Along with the increase of fossil fuel use amount, make CO in the atmosphere
2Concentration still keeps the trend that increases year by year, and the only burning of coal and oil just has billions of tons of CO every year
2Gas enters atmosphere, and mostly concentrates on the following atmosphere of 20km, causes the iceberg, polar region to melt, and sea level rise, and the abominable meteorologic phenomena in the whole world frequently takes place.Show the CO in the atmosphere in 1880 according to a large amount of monitoring and statistics results
2Content had only 284mg/L, reached 350mg/L to 1980, estimated that the year two thousand fifty can increase to 415-480mg/Nm
3, the CO of computation of Period per year
2Concentration has rising year after year, has destroyed the balance between sun projectile energy and the loss energy, causes that the energy balance of earth surface changes and global warming.Not only dust, SO in the flue gas of the burning and exhausting of fossil fuel
2, NO
2Need control Deng pollutant, in the face of the new demand of global environment, must be to CO
2Administered, to bear the responsibility of global environmental change.People are NO in the control flue gas
x, SO
