System is mainly used in power plant, metallurgy, the industrial circles desulfurization fume disposal field such as chemical industry.
Background technique
Rotary spraying and drying method semi-dry desulphurization technology is because of its desulfuration efficiency height, without advantages such as waste water in national flue gas desulfurization
Field is widely used.The sulfur removal technology sweetening process is that quick lime adds water to be configured to the lime (Ca that solid content is 20%-25%
(OH)2) slurries, it is sprayed into absorption tower by the droplet that atomizer is atomized into 30-80 microns, lime white droplet (absorbent) in tower
Wink speed absorbs the SO in flue gas2, reach removing SO2And the purpose of other acid mediums.Meanwhile the waste-gas heat wink dry penetrating of rapid-curing cutback
Drop in tower forms dry solid powder-material, is trapped by sack cleaner.
Rotary spraying and drying method semi-dry desulfurizing process principle are as follows: quick lime adds water to react to form Ca (OH)2And it is configured to
Solid content is atomized by atomizer and is sprayed into tower, hundreds of millions small droplets are in Ta Nei and smoke contacts in 20-25% qualified slurries
Chemical reaction afterwards is very fast, the main chemical reactions of completion are as follows:
SO2It is absorbed by droplet:
SO2+Ca(OH)2→CaSO3﹢ H2O
Part SO2 completes following reaction:
SO2+1/2O2+Ca(OH)2→CaSO4+H2O
With other acidic materials (such as SO3, HF, HCl) reaction:
2HCl+Ca(OH)2→CaCl2+H2O
2HF+Ca(OH)2→CaF2+H2O
Although when lower there are desulfurization fume temperature, system can not normally make currently, the sulfur removal technology is widely used
