Designed technology allows not only to clean the air from aerosols, but
also convert gaseous organic and inorganic admixture in aerosols.
The process of removal of various inorganic and organic gaseous
admixtures and odors from flue gases is realized in the same units as
described above. The treating of gaseous admixtures is effected while
passing of the flue gas cooled to a temperature below 100 oC through the
zone of pulsed corona discharge excited due to action of the pulsed
voltage producing highly active intermediate particles (such as ions and
radicals) going into radiation-chemical reactions with the molecules of
contaminants. These reactions result in the conversion of inorganic
gaseous admixtures into harmless gaseous substances or into aerosols or
solid products. As for gaseous organic admixtures, as a rule, they convert
to form primary substances such as CO2 or H2O and in some cases aerosols of lower organic acids or harmless solid products. The removal
of resulting non-gaseous products description above.
