Or the filler of segregation tetrafluoroethene), control the water yield and absorb the sulphuric acid that sulfur trioxide is into 65% or so, from the bottom of towe taphole
Flow out, wherein dissolving and chlorine, fluorine gas.Sulfur dioxide, oxygen, carbon dioxide are discharged from the overhead gas outlet of the tower（Cause
Higher for sulfuric acid concentration, these three gases can not dissolve, and substantially completely discharge is separated.Sulfur dioxide can be reclaimed with otherwise processed.
On the heat exchange graphite bush adopted in one-level heat-exchange apparatus, PVDF layers are scribbled, with non-sticky, resistant to elevated temperatures spy
Point, is difficult to corrode for sulfur-containing smoke gas, increases the service life.
Finally, triple effect evaporation is carried out to 65% or so sulphuric acid using the waste heat of one-level steam and second steam（Containing an effect
Vaporizer, 2nd effect evaporator, triple effect evaporator）Concentration is to 75-78%（Can not be too dense, the easy quilt of the graphite equipment for otherwise touching
Corrosion）.Second steam temperature is relatively low, for 1st effective evaporator, the moisture in the sulphuric acid of pre-evaporation 65% or so；One-level steam
Temperature is higher, for triple effect evaporator, further evaporates the sulphuric acid of the moisture concentration to 75-78% in sulphuric acid.
The mixed vapour of one-level steam and second steam can be adopted in 2nd effect evaporator, moderate temperature, heat is suitable.
This means, by sulfur-containing smoke gas entrance connect based on graphite material made by one-level heat-exchange apparatus, one-level heat exchange sets
