Background
Flue gas refers to high-temperature gaseous substances which are generated in industrial production and are harmful to the environment, such as sulfur oxides (mainly sulfur dioxide), carbon monoxide and nitrogen oxides generated when fossil fuels such as coal and petroleum are combusted and discharged through a flue or a chimney. The emission of large amounts of sulfur oxides and nitrogen oxides can lead to environmental problems such as acid rain, vegetation damage, crop death and building corrosion. Meanwhile, a large amount of carbon dioxide (accounting for about 37.5 percent of flue gas) is generated by combustion of fossil fuel, global warming is aggravated by emission of the carbon dioxide, and sustainable development of people and nature is greatly restricted. Therefore, monitoring of the component gases in the flue of the factory is beneficial to verifying whether the emission concentration of various pollutants in the flue gas meets the national specified standard, and is also beneficial to the subsequent treatment and disposal of the prominent pollutants.

This approach is widely used in practice, but has certain drawbacks. When the flue gas is tested, the hose connected with the test tube can enter air, meanwhile, the hose stretches into the test tube in the flue due to negative pressure in the flue, the air can be sucked, the air exhaust power of the flue gas analyzer is too small, and the stable reading can be obtained after the air is exhausted for several minutes. When a plurality of flue gas test ports need to be sampled and analyzed, frequent plugging and unplugging of the test tubes can lead to the fact that a flue gas analyzer needs to spend a large amount of time in the whole sampling and analyzing process for exhausting air, and the working efficiency of sample testing and analyzing is seriously reduced.
