A SPRAY DRYER ABSORBER DISPERSER ARRANGEMENT

摘要

A spray dryer absorber (308) is operative for removing gaseous pollutants from
a hot process gas and comprises at
least two dispersers (314, 316, 318, 320, 321 ). Each such disperser is
operative for dispersing a portion of the hot process gas
around a respective atomizer (24), and for providing the respective portion of
the hot process gas with a rotary movement around
the atomizer (24). At least one specific disperser (314) is operative for
providing the hot process gas passing through that specific
disperser (314) with a rotary movement in a direction (FC), which is opposite
to the direction (FCC) of the rotary movement of
the respective portion of the hot process gas dispersed by at least one other
disperser (316) being located closest to that specific
disperser (314).
