Description
Technical field
Particle monitoring sampling system of the present invention, belongs to particle monitoring technical field.
Background technology
Common sampling probe only has flue gas sampling function, is measured for the particulate matter of minimum discharge, low temperature wet flue gas, cigarette
Warm many vapor in 50 degrees centigrades, flue gas are hypersaturated state, contain a large amount of drops.Its drop composition contains substantial amounts of
Calcium ions and magnesium ions and sulfate ion and calcium oxide solid content.
The concentration of particulate matter is low, typically in 20mg/m3Hereinafter, many units are in 10mg/m3Below.The composition of particulate matter and
Property is complicated, is liquid aerosol and solid aerosol and deposits state, according to the particulate matter measurement standard of the newest revision of China,
It just can must be discharged particle in the solid particulate matter of more than 105 degree operating mode formation of flue gas to ask particulate matter measurement, entered
And measure.
The content of the invention
