Description
Technical field
The utility model is related to technical field of environmental detection, more particularly to a kind of sulfuric acid mist extracts sampling apparatus.
Background technology
The smog that sulfuric acid particles are formed that sulfuric acid mist also makes acid mist be often referred to largely float has fossil-fuel-fired or ore deposit
The sulfur-containing oxide waste gas discharged during thing smelting, sulfuric acid generation etc. is caused, and is a kind of atmosphere pollution phenomenon.Three in smoke evacuation
Sulfur oxide is combined generation sulfuric acid mist with water vapor in air, and sulfuric acid mist is easily adsorbed on particulate matter, particulate matter in China's environment
Content is higher, and the sulfuric acid mist in waste gas is main to be existed with sulfuric acid, sulfur dioxide, sulfur trioxide and soluble sulphate.Its danger
Evil effect is bigger than sulfur dioxide 10 times.Acid Rain Pollution scope constantly expands as caused by sulfur dioxide (SO2) emissions, by the beginning of the eighties
Southwestern some areas, extend to southwest, Central China, the most area in south China and East China, at present average annual precipitation pH value be less than 5.6
Area accounted for 40% of national area or so.Acid rain and sulfur dioxide pollution harm residents ' health, corrode construction material, destruction
